• Aspects related to water consumption of P. peruviana were evaluated under different managements. • P. peruviana vegetative growth is favored by high temperatures. • Mulching reduced Kc values of P. peruviana in all phenological stages. • The Kc of P. peruviana can be estimated by means of NDVI. • Recycled paper mulch reduced soil evaporation and water consumption by the P. peruviana crop by 30.6%. The application of soil mulching has been widely used to increase crop production; however, few research studies have comprehensively evaluated the use of recycled paper as soil mulch and its effects in relation to water savings and crop coefficients. The objective was to evaluate the effects of mulching with recycled paper on evaporation and evapotranspiration of Physalis peruviana and to determine the crop coefficients in its development stages. The study was carried out in two cultivation cycles at the Lysimetric Station of Viçosa, MG, Brazil. The experiments were set up in a randomized block design with four replicates, where four lysimeter treatments were applied: P. peruviana cultivation without recycled paper mulch (C); P. peruviana cultivation with recycled paper mulch (CP); lysimeter with only recycled paper mulch (P); and lysimeter cultivated with Bahiagrass (G). Irrigation and drainage volumes in each lysimeter were measured daily to calculate crop evapotranspiration (ETc), reference evapotranspiration (ETo) and, therefore, the crop coefficients (Kc). In addition, crop phenology, fruit characteristics, gas exchange, yield and normalized difference vegetation index (NDVI) were also evaluated. For the first cultivation cycle, over 218 days, the values of water consumption in the lysimeters C, CP, P and G were 405, 291, 88 and 444 mm, respectively. For the second cycle, over 206 days, the values of water consumption were 416, 279, 94 and 331 mm, respectively. Recycled paper significantly reduced water consumption, especially in the initial and late-season stages, also reducing Kc values. The Kc values for P. peruviana were 0.25, 0.55, 1.05 and 0.46 in cultivation with mulch and 0.45, 0.85, 1.35 and 0.48 in cultivation without mulch for the initial, development, mid-season and late-season stages, respectively. NDVI can be used to estimate the Kc values of P. peruviana. Recycled paper mulch reduced water consumption by 30.6% and increased gas exchange and yield of P. peruviana in cycles 1 and 2, respectively. [ABSTRACT FROM AUTHOR]

A method for determining thallium in water samples via solid sampling high-resolution continuum source graphite furnace atomic absorption spectrometry (SS HR-CS GF AAS) after preconcentration using chromatographic filter paper as a solid support was proposed. The effects of pH, stirring time, and sample volume in the analyte preconcentration step were studied. The presence of potential interferences in the sample and the type of masking agent were also examined. In the proposed procedure, the sample was placed in contact with the solid phase in a polypropylene tube, and after stirring for 3 min, thallium determination was performed via HR-CS GF AAS directly on chromatographic filter paper. A preconcentration factor of 55, a precision of 9.4% (n = 10; 10 μg L−1), a limit of detection of 0.018 μg L−1, and a limit of quantification of 0.059 μg L−1 were achieved. Analyte addition and recovery tests were performed, and the results ranged from 91% to 110%. The accuracy of the method was evaluated by analyzing a water reference material. The procedure was used to determine thallium in water samples collected in Barreiras, Bahia, Brazil. The results were compared with those obtained using inductively coupled plasma‒mass spectrometry (ICP‒MS). Thallium concentrations in the analyzed samples ranged from <0.059 to 0.80 μg L−1. [Display omitted] • A method for Tl determination in water samples using SS HR-CS GF AAS is presented. • Thallium preconcentration using chromatographic filter paper as a solid phase was performed. • Thallium determination was carried out via HR-CS GF AAS directly on chromatographic paper. • This method was used to analyze river water samples.

[Display omitted] • Five Brazilian coats of arms paintings are characterized in a microanalytical approach • Artist's palette comprises traditional pigments such as ultramarine blue, indigo, Prussian blue, lead chromate and vermillion • Aluminium and brass are found in silvering and gilding instead of silver and gold, contradicting heraldic guidelines • Differences in the colorant palette and signature raise questions about the authorship of a painting • Crystalline efflorescences in one painting may indicate paint extender migration or past microbiological activity Heraldry in Latin American art of the twentieth century can be considered rare. In this context, the material composition of coat of arms paintings on paper attributed to the Brazilian painter José Wasth Rodrigues is investigated for the first time using a microanalytical approach. Microsamples from 5 municipal coats of arms dated 1932 were analysed using Raman microscopy, Attenuated Total Reflection Fourier Transform Infrared spectroscopy (ATR-FTIR), and Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS). SEM-EDS results revealed the artist's choice of using metallic aluminium and brass in the representation of silver and gold colours, respectively. Raman microscopy analyses showed the use of traditional inorganic pigments, such as ultramarine blue, indigo, Prussian blue, yellow chromates and vermillion. In contrast, the results showed that the painting with an unusual signature attributed to the artist (W. instead of J.W.R, commonly found) contains synthetic organic dyes Orange 5, Red 53, and Yellow 1 (introduced in the 1900s). This discovery raised hypothesis of questioning authorship for this particular painting. ATR-FTIR analysis of a paint fragment from one painting confirmed the use of gum arabic as a binder. ATR-FTIR analyses of efflorescences collected from a blue paint layer of a particular coat of arms suggest protein and lipid content, raising suspicion of either the use of the tempera technique in this particular paint or remains of a past microorganism activity. Robust information was obtained on the chemical characterization of the coat of arms, enhancing comprehension of the painting techniques employed by the artist and providing insight into the production of heraldic art in Brazil at the beginning of the 20th-century.

For the first time, a cutin-like, highly chemically resistant macropolymer has been isolated from rachises of Karinopteris sp. (lyginopteridalean pteridosperm, Middle Pennsylvanian). Samples are obtained from a cuticular or "paper" coal-shale, i.e., an organic-rich and highly clastic rock associated with the Upper Block Coal Member of the Brazil Formation, Parke County, west-central Indiana, U.S.A. Karinopteris specimens are preserved as naturally oxidized compressions, termed "fossilized cuticles", and possibly represent vegetation of mineral substrate environments. Employing laboratory oxidation reactions, the fossilized cuticle of Karinopteris rachises is used to obtain the cuticle. After additional and long-term oxidation treatment, the cuticle yields the cutin-like macropolymer, here referred to as "cutin" for simplicity. The fossilized cuticle, cuticle, and cutin samples of Karinopteris sp. are chemically analyzed using semi-quantitative Fourier transform infrared (FTIR) spectroscopy. Cutin IR spectra of Karinopteris rachises are characterized by (a) a predominantly aliphatic composition as indicated by intense aliphatic (CH al) C H stretching peaks at 3000–2700 cm−1, which are assigned to methylene (CH 2) and methyl (CH 3) groups; (b) carbonyl (C=O) groups at 1730–1640 cm−1, and aromatic carbon (C=C) absorption bands at 1600–1500 cm−1. A comparison with the cuticle, the cutin stands out due to relatively higher values of CH 2 /CH 3 and C=O/C=C, while displaying notably low values of CH al /C=O and C C contribution. Specifically, the relatively low value of CH al /C=O ratio obtained for the cutin of Karinopteris rachises is consistent with those found in the cutin of extant and fossil leaves. This lower CH al /C=O ratio indicates the important role likely played by C O groups in creating a deformable and flexible structure in both the cutin and the cuticle. Such a reduced rigidity suggests a high level of rachis flexibility of the once-living Karinopteris plant, supporting the interpretation of a climbing or liana habit. Cutin isolation and its chemical characterization shed light on the probable biomechanical (flexibility) properties of Karinopteris rachises, thereby enhancing our understanding of the plant growth habit. [Display omitted] • First-time spectroscopic study of Indiana "paper" coal (Pennsylvanian, U.S.A.). • Cutin polymer is obtained from fossilized cuticles of Karinopteris rachises. • Fourier transform infrared spectroscopy supplies chemical data. • Cutin is mainly aliphatic with highly crossed-linked ester carbonyl (C=O) bonds. • High C O contents suggest a liana-like Karinopteris plant with flexible rachises.

• The study of plant–plant parasitism has experienced remarkable growth in the scientific literature. • Research on plant parasites has predominantly focused on ecological and physiological aspects in the last 20 yeras. • Aspects of evolution and host-parasite interactions needs further and deeper investigations. • We hope this special issue will serve as a catalyst for further advancements in the investigation of plant-plant parasitism. The study of plant–plant parasitism has experienced remarkable growth in the scientific literature, particularly over the past two decades. Hemi- and holoparasites, in particular, have been recognized as pivotal components within plant communities, capable of upscale effects to the ecosystem. Research on plant parasites has predominantly focused on ecological and physiological aspects of parasites and hosts, with a global distribution pattern. However, some fields remain relatively unexplored, and specific regions of Asia and the Global South (with exception of Australia and Brazil) have yet to receive comprehensive attention. Here, we introduce the theme on plant hemi- and holoparasites and explore publication trends on plant–plant parasitism over the past half-century, with a particular emphasis on papers published within the last two decades. We explore our findings to extend an invitation to researchers from diverse backgrounds and disciplines to contribute their expertise to a forthcoming Virtual Special Issue of Flora – Morphology, Distribution, Functional Ecology of Plants on "Plant Parasitism: Ecology, Evolution and Functional Aspects", with contributions expected from a wide range of topics related to ecology, physiology, morphology, systematics, and reproductive biology. We believe that this special issue will help in advancing our knowledge in plant-plant parasitism, fostering collaboration and facilitating the growth of this exciting area of research.

Production systems are being restructured to close production cycles via implementing circular economy (CE) practices. The planted tree industry in Brazil has shown potential for applying CE practices due to its efficient use of resources and inclination towards environmental innovation. However, some gaps and difficulties have been observed in several industrial segments so that the logic of the circular production system is put into practice more effectively and intensely. In this context, the aim was to investigate the use and impacts of CE practices in the Brazilian planted tree industry by sector of operation and scale of enterprises based on the ReSOLVE framework. Data were collected from 34 companies that answered a questionnaire, corresponding to 47.2% of Brazilian planted tree industry companies. Data analysis involved univariate and multivariate statistical techniques, considering the grouping of companies by sector of activity (forest producer, pulp and paper, and timber processing) and scale (small, medium, and large). The results revealed that "pulp and paper" and medium- and large-scale companies had the most significant application of CE practices and reported more significant impacts. [Display omitted] • Explores a segmented analysis of the circular economy by scale and sub-sector groups. • Scores of circular practices and their impacts are presented according to the groups. • The association between circular practices and impacts by group are analyzed. • Propositions to enable the adoption of circular practices are presented.

The attribution of status carries significant social and reproductive advantages as it reflects individual qualities. However, the traits conveyed and those perceived do not always align with reality. It is crucial to understand how the status associated with different professions can influence the perception of traits, as it assists in decision-making during social interactions. This study aimed to investigate whether the status derived from university education influences the assessment of social status, mate value and personality traits among Brazilians. A quasi-experimental design with nonrandom assignment was used, employing online questionnaires administered through Google Forms. A total of 252 participants, both male and female, over 18 years of age, and residing in Brazil, took part in the study. These participants evaluated the social status, mate value, and personality traits of stimulus subjects with high and low-status university education. The results revealed that stimulus subjects with high-status university education were regarded as possessing higher status in society and scored higher on Dark Triad traits. In contrast, stimulus subjects with low-status university education were perceived as having greater agreeableness, emotional stability, and openness to experiences. In conclusion, university education signals social and personality traits, serving as a parameter to shape social perceptions. • Subjects with high-status backgrounds are rated higher on Dark Triad traits. • Low status indicates greater agreeableness, emotional stability, and openness. • University education serve as an indicator of social and personality traits. • University education affects the perception of the individuals in social hierarchy.

Biodiversity markets offer considerable promise but are accompanied by controversies. Here, we map the utilization of native species (NS) from Brazil's biodiversity across eleven industrial sectors: foodstuffs, beverages, textiles, clothing, leather, wood, pulp and paper, biofuels, pharmochemicals, rubber and furniture. We show that there exists a diverse range of NS use in industrial products (48%) and activities (73%). These economic activities represent potential annual exports of approximately USD $50 billion. However, we found that only 1% of the potential business, USD $500 million of annual exports, is consolidated and can be traced to such products. We show that biodiversity markets and larger annual revenues locate in municipalities away from places in which biodiversity products originate. Therefore, the biodiversity business in Brazil remains largely untapped. This prompts a critical examination of the role of biodiversity within the Brazilian industry and its alignment with the Brazilian Biodiversity Law and the Nagoya Protocol. Our study is a pioneering effort that provides strategic recommendations. We suggest that the responsibility for sustainable NS utilization predominantly falls on sectors dominated by major corporations, most notably pharmochemicals and biofuels. These industry sectors possess the potential to lead the transition towards responsible and sustainable biodiversity practices within Brazil. [ABSTRACT FROM AUTHOR]

The high costs of environmentally responsible and socially just approaches are some of the factors that hinder the implementation of sustainable projects in the industrial sector. However, upstream collaborative integration in the corrugated cardboard industry in southeastern Brazil is a reality. In this context, this study aimed to highlight the structure of a collaborative sustainable project in the context of the corrugated cardboard industry, to analyze ESG risk management in the corrugated cardboard industry in the Southeast Region of Brazil, the relationship between ESG risk management and social responsibility in corrugated cardboard industries, the strengths and weaknesses of risk management models in use by the consulted participants, and to propose innovations regarding risk analysis, applicable in sustainable projects with a collaborative bias. The methodology adopted was the case study, with consultation with managers in professional activity in the industrial sector, corroborated by document analysis and systematic review of the literature. We identified preliminary risk analysis (PRA) and failure mode analysis (FMEA) as key practices used by managers in the corrugated paper industry in the region. These practices are insufficient in the convergence of objectives, engagement with the community, and extension of the lifecycle of products and processes. Our findings show that the sustainability of a project may be an extension of the risk analyses carried out in the initial phase, mainly about strategic decision-making and the operationalization of investments. Without bias to the need for risk analysis, the life cycle analysis is also an effective way of highlighting the critical factors, weaknesses, and strengths of a sustainable project. The study indicates the so-called GUT matrix approach (gravity – urgency – tendency) as the most suitable for innovation in risk analyses oriented towards sustainable projects in the analyzed sector.

This article estimates the potential of using depleted offshore gas fields in Brazil for hydrogen storage and the effects this may have in terms of energy security. Brazil is starting to invest in producing green hydrogen associated with offshore wind energy generation. This initiative has stimulated the search for suitable locations to store hydrogen, including in depleted offshore gas reservoirs. The methodology used in this paper allows for identifying which of the 85 assessed depleted offshore gas fields are the most suitable for hydrogen storage and evaluating the storage capacity of the selected fields. In addition, a wind speed analysis is made to investigate possible locations for prospective wind energy generation projects that can accommodate green hydrogen production. As our main result, we find that the selected depleted offshore gas fields have the potential to store around 5483 TWh worth of hydrogen. This amount is equivalent to about 10 times the total annual electricity consumption in Brazil. Hence, Brazil can comfortably leverage its offshore wind potential in connection with hydrogen production to enhance the energy security of its electricity supply. Considering that to date primarily natural gas has been used as the main source of energy security in Brazil and that its share in the electricity sector has significantly increased over the last decade, the combination of hydrogen storage and renewable energy such as offshore wind power has the potential to provide a resilient and decarbonised electricity system in the country. Furthermore, hydrogen stored in offshore reservoirs in Brazil can become an important resource in the international energy market and constitute a possible key to energy security for countries to which Brazil may export hydrogen. We end our paper by providing comments on the challenges, opportunities, and prospects of offshore hydrogen storage in Brazil. • Offshore natural gas fields in Brazil are suitable for hydrogen storage. • Depleted offshore gas fields can store around 5483 TWh worth of hydrogen. • Two main offshore storage clusters exist in the Southeast and Northeast of Brazil. • Fossil fuel dependence in Brazil can be reduced through hydrogen use and storage. • Large-scale hydrogen storage can contribute to Brazil's energy security.

Temperature cycling stability studies can be appropriately designed and utilized to ensure that drug product quality, efficacy, and safety are not compromised when materials are subjected to short term temperature excursions from intended storage that may occur during e.g., shipping, transport, or patient use. Some countries, such as Australia and Brazil, impose specific regulations that specify the need to conduct stability studies that are supportive of "real world" excursions as part of licensing approval requirements. These temperature cycling stability studies extend beyond what is described in ICH Guidelines Q1A(R2) and Q5C, and companies may be challenged in designing studies that not only satisfy country specific regulations, but also satisfy all global regulatory health authority expectations. This article focuses on responses to a cross-industry survey conducted within the International Consortium for Innovation and Quality (iqconsortium.org) member companies, regarding practices related to temperature cycling stability studies, in order to determine how these requirements are being interpreted and met. The results indicate that while there is no one-size-fits-all approach to performing temperature cycling stability studies, there are common and best practices that can be followed to satisfy global health authority regulatory guidelines and requirements. The purpose of this paper is to describe the outcome of an industry survey and common/best practices on temperature cycling stability studies performed on drug product (DP) to satisfy the requirements established for marketing authorizations in Australia and Brazil or any other countries that may have similar requirements. The framework is proposed within the context of late phase and commercial development of common biological and/or large molecule modalities, such as monoclonal antibodies (mAbs, including bispecific antibodies), fusion proteins, complex proteins, oligonucleotides, and antibody-drug conjugates (ADCs), but many of the general principles involved may be applied to other therapeutics, such as Virus Like Particles (VLP), gene or cell therapies (GTx or CTx), or vaccines. For the purposes of this paper, temperature cycling stability studies refer to studies that are designed, in part, to support short term temperature excursions that drug product may be subjected to during shipping and storage activities and is outside of the labeled storage condition of the product.

The main objective of this paper is to propose a novel SEIR stochastic epidemic model. A distinguishing feature of this new model is that it allows us to consider a setup under general latency and infectious period distributions. To some extent, queuing systems with infinitely many servers and a Markov chain with time-varying transition rate comprise the very technical underpinning of the paper. Although more general, the Markov chain is as tractable as previous models for exponentially distributed latency and infection periods. It is also significantly more straightforward and tractable than semi-Markov models with a similar level of generality. Based on stochastic stability, we derive a sufficient condition for a shrinking epidemic regarding the queuing system's occupation rate that drives the dynamics. Relying on this condition, we propose a class of ad-hoc stabilising mitigation strategies that seek to keep a balanced occupation rate after a prescribed mitigation-free period. We validate the approach in the light of the COVID-19 epidemic in England and in the state of Amazonas, Brazil, and assess the effect of different stabilising strategies in the latter setting. Results suggest that the proposed approach can curb the epidemic with various occupation rate levels if the mitigation is timely. • We propose queue-based stochastic epidemic model for viral epidemics. • The model is tractable yet general and applicable to large populations. • It describes epidemics with general latency and infectious periods. • We derive a control rule that ensure a shrinking epidemic. • Our experiments illustrate the effectiveness of the proposed control rule.

Despite ample evidence on the labor productivity impact of heat shocks, little is known about how heat shocks affect labor adjustment over time. This paper uses administrative employer–employee linked data from Brazil to examine margins of labor market adjustment to extreme heat. Tracking workers over time and across job spells, I find that quarterly heat shocks increase the probability of formal manufacturing layoffs. In the medium run, there is limited intersectoral and interregional reallocation, as well as a significant failure rate to reallocate back to formal sectors, indicating job transitional costs. Finally, the employment impact of heat shocks is larger for workers in more routine manual task intensive, less abstract occupations. [ABSTRACT FROM AUTHOR]

Animal venoms are a rich and complex source of components, including peptides (such as neurotoxins, anionic peptides and hypotensins), lipids, proteins (such as proteases, hyaluronidases and phospholipases) and inorganic compounds, which affect all biological systems of the envenoming victim. Their action may result in a wide range of clinical manifestations, including tachy/bradycardia, hyper/hypotension, disorders in blood coagulation, pain, edema, inflammation, fever, muscle paralysis, coma and even death. Scorpions are one of the most studied venomous animals in the world and interesting bioactive molecules have been isolated and identified from their venoms over the years. Tityus spp. are among the scorpions with high number of accidents reported in the Americas, especially in Brazil. Their venoms have demonstrated interesting results in the search for novel agents with antimicrobial, anti-viral, anti-parasitic, hypotensive, immunomodulation, anti-insect, antitumor and/or antinociceptive activities. Furthermore, other recent activities still under investigation include drug delivery action, design of anti-epileptic drugs, investigation of sodium channel function, treatment of erectile disfunction and priapism, improvement of scorpion antivenom and chelating molecules activity. In this scenario, this paper focuses on reviewing advances on Tityus venom components mainly through the modern omics technologies as well as addressing potential therapeutic agents from their venoms and highlighting this abundant source of pharmacologically active molecules with biotechnological application. [Display omitted] • Tityus venoms are still underexploited sources of pharmacological agents. • Only few Tityus venom sequences (of ∼3000 available at databases) have been studied in depth. • T. serrulatus venom is the most studied venom among the Tityus venoms. • Many Tityus toxins are versatile toxins presenting a broad spectrum potential. • Some Tityus venom components whose function is still unknown include the PAPE and anionic peptides.

Contemporary societal challenges put in evidence the need to improve the hard and soft skills of chemical engineering students. To promote a more student-centered approach, active-based learning, and improved assessment strategies, the Brazilian government approved the so-called New National Curriculum Guidelines (NCG) for engineering courses. To comply with those guidelines, the Department of Chemical Engineering of the Polytechnic School of the University of São Paulo (USP) is currently developing an educational modernization process sponsored by the Fulbright Commission in Brazil, called Special Program for Modernization of Undergraduate Education (PMG). The project is based on three pillars of modernization: content (what), form (how), and infrastructure (where). This paper describes initiatives in each of those pillars: content and format changes in Chemical Reaction Engineering and Process Safety courses and the creation of new spaces for a student-centered approach (an innovative classroom layout and a makerspace). By gathering two concrete classroom experiences guided by a broader institutional educational policies (the PMG project and the NCG), this paper highlights that slight changes can lead to great improvements in the learning process, leading to more engagement in the development of hard skills while favoring improvements in soft skills, such as communication, team-based work, and critical thinking. • Presents a modernization program under implementation at Universidade de São Paulo. • Discusses modernization from a triaxial perspective of content, form and infrastructure. • Reports the feedback of a PBL initiative for soft-skills development in a CRE course. • An active-based methodology in a Process Safety course is presented and discussed. • Presents two new infrastructural changes to facilitate the development of soft-skills.

This paper analyses the effects that the Itaipú Hydropower Plant has had in the development of capabilities and the evolution of energy security aspects in Paraguay and Brazil. To do this, it applies a theoretical framework that integrates elements from the energy security literature with the concept of capabilities. Applying the framework sheds light on the evolution of the financial, organisational, and technical capabilities that developed in connection with the building and operation of the dam and its impact on energy security in both countries. The research design of the study is an in-depth case study drawing on qualitative data including original interviews collected between 2020 and 2021 as well as on an extensive review of official documents and statistical data. The paper finds that the dam had a deep and lasting impact in the evolution of the electricity sector in both Paraguay and Brazil with positive as well as negative impacts in energy security across all the analysed dimensions. The paper presents relevant case specific conclusions as well as general implications of the findings that emerge and can potentially inform similar situations in other settings where large electricity endowments are shared by two or more countries, irrespective of the technology. • Integrates elements of energy security and technical, organisational, and financial capabilities • Presents original research on the impacts of the Itaipú hydropower plant • Contrasts impacts of transboundary hydropower in Paraguay and Brazil • Draws on original qualitative and quantitative data collected in three countries [ABSTRACT FROM AUTHOR]

Indirect evaporative cooling is a technology that can be used sustainably to replace traditional cooling systems using thermodynamic compression cycles, especially in tropical countries like Brazil, which have many regions with hot climates and low relative humidity. These meteorological aspects favor the simultaneous transfer of heat and mass, allowing the thermal cooling effect characteristic of evaporative cooling processes. Thus, this paper investigates the performance of a sustainable air cooling system by combining the psychrometric effects of warm, dry air with the flow features inside a cyclone covered by a layer of a fabric moistened with water. Fluid dynamic simulations previously indicated temperature decreases of up to 12.2 K between the feed and overflow streams of the cyclone. In addition, temperature contours showed that the fluid dynamics of the cyclone provide instantaneous thermal exchange between the walls and the internal fluid. These results directed the study to execute an experimental design using the response surface methodology to evaluate the influence of some variables in the process. The decrease in air stream temperature ranged from 3.9 to 13.1 K, with relative humidity and ambient temperature being the most significant variables. The results also indicated that water consumption to maintain the fabric wet is relatively low since 16·10-3 kg of liquid is required to cool 1 m³ of air flowing through the cyclone. [Display omitted] • High inlet temperature and low relative humidity provided maximum thermal gradients. • Within 0.75 s, in average, the system provided a thermal reduction of up to 13 K. • The thermal efficiency of the wet-bulb for the new system varied from 54.8 to 67.8 %. • Dimensionless numbers for psychrometric cooling system showed a linear behavior.

Low carbon agricultural techniques, which aim to reduce agricultural emissions without compromising productivity, are being widely adopted as one strategy to promote more sustainable food systems. Evaluating the impact of such practices requires an effective monitoring, reporting and verification (MRV) system. To our knowledge, no MRV system has been designed or implemented for monitoring and measuring the impacts of the adoption of low carbon agricultural practices. The goal of this paper is to explore the opportunities and challenges of developing a large scale MRV system for low carbon agriculture in Brazil - a major global food producer. The analysis presented in this paper is based on primary data, collected through interviews and conversations with experts, and secondary data from a literature review as well as from public and private databases. Hence, we discuss the three phases of monitoring, reporting and verification. In each case, we analyze the informational needs of an MRV system, evaluate the strengths and limitations of available tools to collect and process these data, and present a vision of how these constituent parts could form a comprehensive MRV system for Brazil. Our analysis reveals technical and governance challenges. On the technical side, challenges include the need to develop emissions factors to calculate mitigation across a range of biomes and low carbon agricultural techniques, and the high costs of gathering and verifying information on farm level. On the governance side, there is a need to generate economic incentives for farmers to share private, farm-level data with a public MRV system. The MRV system could help producers to demonstrate adoption and mitigation, giving them improved access to low-interest credit or certification programs. We conclude that the implementation of a large scale MRV system for low carbon agriculture demands an integrative approach based on a hybrid public-private governance system that prioritizes cost-effectiveness and facilitates smooth information transfer. • Low carbon agriculture needs Monitoring Reporting and Verification (MRV) systems for measuring and reporting GHG emissions. • We propose an MRV system for Brazil, a country that has huge mitigation potential due to its agricultural activity. • Primary farm-level data about adopted techniques could be combined with remotely-sensed and secondary data about land use. • A hybrid public-private governance strategy could reduce costs and create incentives. • Brazil's case is a relevant benchmark for MRV systems in other countries.

[Display omitted] • Assessment of the status and trends of PV DG in Brazil based on big data processing; • Application of machine learning algorithms to estimate the installed power of individual systems; • Application of forecasting models to predict the installed power of PV DG over time in Brazil and its regions; • Application of the DEA method to rank Brazilian states in terms of efficiency in PV DG deployment; • The paper is expected to be valuable for regulatory agencies, researchers, and PV aggregator companies. The deployment of photovoltaic (PV) distributed generation (DG) has been increasing substantially in Brazil. In this context, the present paper exploits a robust dataset provided by the Brazilian Electricity Regulatory Agency (ANEEL) to evaluate the status and trends concerning PV DG. As of Nov/2022, such a dataset consists of more than 1,4 million lines (one for each system) and thirty columns (various information concerning the systems). For an in-depth assessment, three items are addressed: (i) the application of machine learning algorithms to estimate the installed power of individual systems based on other information available in the dataset, (ii) the application of forecasting models to predict the installed power of PV DG over time in Brazil and its regions, and (iii) the application of the data envelopment analysis (DEA) method to rank Brazilian states in terms of efficiency in PV DG deployment. While items (i)-(iii) present distinct specific goals, they use the same dataset and provide essential insights concerning PV DG in Brazil. In item (i), elastic net (EN), decision tree (DT), random forest (RF), extra tree (ET), AdaBoost (AB), and gradient boosting (GB) are applied to select the most accurate algorithm. In item (ii), autoregressive integrated moving average (ARIMA), seasonal autoregressive integrated moving average (SARIMA), Holt-Winters exponential smoothing (HWES), Bass diffusion model (BDM), and multilayer perceptron artificial neural network (MLP-ANN) are applied. In item (iii), output-oriented DEA CCR and BCC are applied. Concerning item (i), results demonstrate that estimating the installed power of individual systems is not very simple. Nonetheless, the machine learning algorithms imply a significant accuracy increase compared to taking the dataset's average as the estimation, especially the DT and RF algorithms with a coefficient of determination of 29%. Regarding item (ii), results demonstrate that the installed capacity in Brazil and its regions is expected to increase approximately linearly in the horizon of months but with weekly seasonal characteristics. Moreover, the most accurate model depends on the region, i.e., the ANN is superior for the Northeast (MAPE of 3.25%) and South (MAPE of 1.28%) regions, the HWES method is superior for Brazil (MAPE of 0.51%) and the Southeast region (MAPE of 2.26%), and the BDM is superior for the Mid-west (MAPE of 1.95%) and North (MAPE of 3.37%) regions. Concerning item (iii), results demonstrate that DEA CCR is more representative of the Brazilian reality since DEA BCC assigns several states as efficient, even if they showcase a very low installed capacity, particularly small states. DEA CCR indicates that Minas Gerais, Rio Grande do Sul, and Mato Grosso are the most efficient states in PV DG deployment relative to their inputs, closely followed by São Paulo with an efficiency of 95%. Furthermore, states located in the North and Northeast region require more attention from ANEEL since their efficiencies are generally low. A literature review demonstrated that this paper is the first of its kind in exploiting so thoroughly and robustly the dataset provided by ANEEL. Therefore, the paper is expected to assist ANEEL in the task of properly regulating the sector and also assist researchers and PV aggregator companies through in-depth insights. Moreover, the conducted procedures can also be applied to other countries with available datasets, thus ensuring high applicability for the research. [ABSTRACT FROM AUTHOR]

This paper presents a new approach to calculating the levelized cost of hydrogen (LCOH) using a stochastic model under an uncertainty and risk perspective. The research problem is associated with how to integrate the concept of financial risk to assess investments in small-scale green hydrogen production for more robust results, resolving issues related to underlying economic and technical factors, often overlooked, that may impact the production of green hydrogen in Brazil and Germany. The approach is applied to an investment project at two localities: Itajubá, Brazil, and Cologne, Germany, to investigate the underlying economic and technical factors that may impact the production of green hydrogen. In this stochastic approach, the Value at Risk (VaR) is calculated with a confidence level of 95% for 5000 LCOH values for each city, generated by the Monte Carlo Simulation (MCS). MCS results show that a correlation between assumptions (uncertainties) significantly affects LCOH with more favorable conditions to produce green hydrogen in Cologne. The risk analysis results show a significant difference concerning the deterministic approach when implementing the risk measure with VaR-LCOH of US$8.39 for Itajubá and VaR-LCOH of US$8.21 for Cologne. • Green hydrogen Investments are evaluated techno-economically in Brazil and Germany. • A Monte Carlo approach under uncertainty and risk conditions is implemented. • A stochastic LCOH based on VaR-LCOH metric is proposed to evaluate the risk. • The different nuances that the assumptions assume in calculating LCOH are discussed. • The risk analysis shows a difference regarding the deterministic approach.

This paper aims to examine the effects of fiscal policy on economic growth in Brazil between 1999 and 2017. For this purpose, a novel methodology is applied, using a Vector Autoregressive with Mixed Frequency (MIDAS-VAR) model, proposed by Ghysels (2016), which allows for the estimation of the spending multiplier by measuring the impact of high-frequency data at low-frequency and vice versa. The impact of various types of spending on the gross domestic product (GDP) is analyzed, including primary expenditure, personnel, social benefits, subsidies, investment, and costing, while the central government's primary revenue is used as the revenue variable. The expenditure and tax revenue are the high-frequency variables (monthly observations), whereas GDP is a low-frequency series (quarterly). The estimated fiscal multipliers for primary spending are less than one, suggesting no significant Keynesian effect on output, with particular attention given to the investment multiplier, which is estimated to be close to zero. Our results suggest that the frequency of data matters, and government expenditure has no significant impact on real GDP growth in Brazil. Therefore, the ability of Brazilian fiscal policy to influence economic growth may be limited. [ABSTRACT FROM AUTHOR]

• This paper tests whether personal income inequality can be considered exogenous to subsequent economic growth in Brazil. • Using a massive spatial dataset for all the 5564 Brazilian cities observed in 1991, 2000, and 2010, data reject the assumption of exogenous income inequality regarding subsequent growth. • The employed instrumental variable estimators identify causal effects from inequality to growth on average and conditional quantiles. • A decrease by 1 Gini point is associated with an increase in a cumulative economic growth of 2.5 percentage points in the following ten years. • Neglecting the endogeneity of income inequality to economic growth can lead to wrong conclusions. This paper estimates the impacts of personal income inequality on subsequent growth in a massive spatial dataset for 5564 Brazilian cities observed in 1991, 2000, and 2010 using instrumental variables methods. Based on Brazilian cities' data, the Wu-Hausman test rejects inequality exogeneity regarding growth. Instead of assuming exogenous inequality, we relax this assumption and let the data speak for themselves. Our methods identify causal effects between inequality and subsequent growth in conditional quantiles beyond the average. On average, the magnitude of the estimate implies that lowering personal income inequality by 1 Gini point would translate to an increase in a cumulative economic growth of 2.5 percentage points in the following ten years. Our findings call attention to the risk of following Litschig and Lombardi [ J. Economic Growth , 2019, vol. 24, pp. 155–187] when studying the influence of inequality on growth, neglecting the endogeneity of the former to the latter. [ABSTRACT FROM AUTHOR]

Over recent years, and as a result of the recent global health pandemic, resilience has become increasingly central to contemporary policy discourses in urban planning and development in both the Global North and Global South. Drawing from ongoing empirical studies of community resilience and everyday practices that have been co-designed and co-produced alongside Brazilian marginalised communities which are highly vulnerable to a range of natural hazards, this paper highlights the growing importance of dialogical stakeholder engagement methodologies in designing alternative urban visions – so-called resilience imaginaries or counter-cities - across the Global South based on social diversity, equity and spatial justice. More specifically, the dialogical participatory mapping approach outlined in this paper utilises citizen science approaches to develop local resilience imaginaries, building on the pedagogical work of Brazilian educator Paulo Freire and the conceptualisation of dialogue as a comprehensive and progressively unfolding methodological approach. Practically, we adopted a range of community engagement approaches that allowed local citizens to become more aware of their own risk context and embed this tacit knowledge into the operation of civil protection programmes. Our empirical results highlight the potential of such dialogical participatory approaches to capture lay knowledge from local citizens and contribute to the development of enhanced resilience approaches. The paper concludes by reflecting on the role of formerly marginalised voices in the advancement of local urban policy and on the novelty and promise of critical pedagogical approaches to co-production within existing regimes of urban governance and the imagining of radically independent counter-cities. • Novel community engagement approaches based on dialogue allow local citizens to become more aware of their own risk context. • The process of geospatial data production can be a transformative moment capable of nurturing enhanced community resilience. • Dialogical participatory mapping is a method for re-imagining future city-visions. • Western resilience scholarship needs learn from emerging resilience building grounded practices in the Global South.

The May 2023 version of Brazil's Fake News Bill (FNB), a proposed new statutory framework for social media regulation, heavily referenced the EU's Digital Services Act (DSA). The literature on regulatory convergence points to the Brussels Effect , praising the EU for wielding unilateral soft power in shaping global regulations. Therefore, based on interviews with Brazilian experts who played a significant role in the regulatory discussion, this study applies Thematic Analysis to assess the DSA's impact on the FNB draft. The article finds limited Brussels Effect due to criticism of its incapacity to address local platform liability concerns and the absence of economic and legal drivers for convergence with EU regulation. Despite this, the study highlights the DSA's positive influence on the local debate in promoting democratic and human rights principles, leveraging the European legislative process to enrich local discussions. Finally, local political factors contributed to a narrative that differed from the DSA, framing the FNB not only as a tool against disinformation, but also as a means to protect democracy. This paper offers an unprecedented case study of the Brussels Effect reach on the global-south, presenting limitations of the EU benchmark when transposed to other regulatory and political contexts. • Two key political factors influenced the FNB's draft. • The DSA serves as a symbolic reference in Brazil's Fake News Bill debate. • The Brussels Effect is limited due to the DSA's incapacity to address local issues. • We identified the lack of economic drivers imposing convergence with the DSA. • The paper offers a case study of the Brussels Effect from a global-south perspective.

Many nations have pledged to reach carbon neutrality by 2050. Embarking on the decarbonization journey, they posited geological carbon storage (GCS) as a pivotal technology within the carbon capture, utilization, and storage (CCUS) framework. The CCUS chain operates to reduce "hard-to-abate" emissions at key sectors by capturing carbon dioxide (CO 2), reusing it, transporting it, or disposing of it via injection into underground geological formations for permanent storage. Despite the global success of GCS ventures, mainly driven by the oil and gas industry, GCS initiatives are still in their early stages in several developing countries. In Brazil, for instance, a full setup covering precise storage capacity databases, potential CCUS clusters, national regulatory structure, and auxiliary computer-aided engineering is underway. Intended to push the frontier in the latter subject, this paper introduces mathematical models for qualifying underground CO 2 storage sites. Our research explores a family of multivariate functionals endowed with underlying reservoir features and distinct weighting functions, thus envisioning two primary objectives. Firstly, it clarifies non-linear interactions between rock and fluid properties using quality indicators. Secondly, it evaluates geographical regions considering structural traps/caprocks settings. Backed by the Matlab Reservoir Simulation Toolbox (MRST) capabilities, the methodology is a subsidiary resource for identifying suitable injection and storage sites. A case study using the UNISIM-I-D model generated dozens of volumetric quality maps that point to unique potential storage sites. Numerical simulation experiments of injection comparing legacy and novel wells reveal storage surpluses improved by up to 50%. The paper seeks to establish foundational knowledge in GCS efficiency for general underground settings. One expects that these outcomes leverage well-repurposing perspectives and stimulate field appraisal actions to scale up GCS projects both in Brazil and worldwide. • Introduction of a family of mathematical functionals for site qualification. • Trap analysis and supercritical gas injection over a Brazilian offshore reservoir model. • Comparison of storage surplus in theoretically-proposed and legacy well locations.

This paper aims to introduce a new sustainable business excellence model, called Knowledge Management Excellence Model 21 (KMEM21), a theoretical framework that combines Knowledge Management and Business Excellence Models (BEMs), proposing an approach applicable to organizations to directly contribute towards achieving the United Nations Sustainable Development Goals (SDGs). The paper through a qualitative-exploratory methodology makes an analysis and benchmarking, emphasizes the integration of Knowledge Management and three specific Business Excellence Models (Management Excellence Model (MEG) from Brazil, Baldrige Excellence Framework, and EFQM). This integration uncovers relationships between organizational concepts associated with Knowledge Management and BEMs, which contributes to new insights in the literature regarding these concepts' interplay. BEMs are presented as tools that can catalyze the power of Knowledge Management towards achieving SDGs. However, it's noted that the existing BEMs might not be adequate, as the goal extends beyond organizational improvement and excellence to encompass sustainable development aligned with SDGs. The article suggests that specific organizational concepts, identified through a literature review and aligned with Knowledge Management and BEMs, can be selected as indicators associated with the constructed KMEM21 and the SDGs. These indicators are intended to form a bridge between the new model and the SDGs. However, given the comprehensive nature of the theory, model development, application, result acquisition, and analysis, the article's primary contribution will be in its focus on elaborating the instrument and technique, demonstrating the creation of a theoretical framework for the SDGs. Future works will showcase the application of the proposed KMEM21 method in five Brazilian organizations, members of Global Compact, to compare the achieved objectives and the results obtained with the organizations' performance and their sustainability reports. [Display omitted] • There is a visible relationship between knowledge management and business excellence models, aided by shared organizational concepts. • Achieving the SDGs in organizations can be done by using the traits incorporated into knowledge management and business excellence models. • The Knowledge Management Excellence Model 21 represents an original approach, acting as a new sustainable business excellence model. • A comprehensive model can be constructed using a methodology that incorporates an instrument, a technique, and a method. • KMEM21 presents a strategic path that aligns with business excellence principles and the sustainable development objectives, offering a framework for organizational success.

Despite promising reductions in mortality from infectious diseases, premature death is a still major public health problem in Brazil. However, little is known about which diseases and injury mechanisms are the main causes of premature death. This paper aimed to detail the trends in leading causes of death among children and adolescents in Brazil. Data were extracted from medical death certificates from the Brazilian Mortality Information System for children and adolescents aged 1–19 years for 2000–2020. The 10 leading causes of death for children and adolescents were defined using primary cause of death codes, grouped by death for diseases and mechanism for injury, according to the ICD-10. All analyses were completed in 2022. From 2000 through 2020, there was a total of 772,729 child and adolescent deaths in Brazil. Despite an overall 34% reduction in child and adolescent mortality from 2000 to 2020, improvements were less pronounced for injury-related deaths than for communicable diseases. Therefore, by 2020, over half of deaths were from injury-related causes. Firearm-related injury was by far the leading cause, accounting for 21% of all deaths. There was a 38% reduction in firearm deaths in the last 4 years against a previously increasing trend, and homicide accounted for over 90% of all firearm deaths because suicide by firearm was rare. Injury-related deaths among children and adolescents are a growing concern in Brazil, and firearms are the current leading cause of child and adolescent death. [ABSTRACT FROM AUTHOR]

In this paper, we described fossils from six mammal taxa (Coendou magnus Cuvier, 1823; Nothrotherium maquinense (Lund, 1839); Tamandua tetradactyla (Linnaeus, 1758); Leopardus wiedii (Schinz, 1821); Didelphis sp.; and Dicotyles tajacu (Linnaeus, 1758)) found in Toca da Barriguda cave (Campo Formoso, Bahia, Brazil). To better understand the isotopic paleoecology of these taxa, AMS radiocarbon dating and carbon and oxygen isotopic analyses were performed. The radiocarbon ages indicate the occurrence of Condou magnus at 33,171–33,765 Cal yr BP, Tamandua tetradactyla at 43,944–44,496 Cal yr BP, Leopardus wiedii at 45,475–46,157 Cal yr BP, and Didelphis sp. at ∼50,227 cal yr BP. Of these taxa, five were carnivorous/omnivorous, only Coendou magnus was herbivorous and lived in low-density forest and arboreal savanna habitats (δ 13C = −12.8‰ to −8.4‰; p i C 3 = 80–90%) during the late Pleistocene. An increase in a dry climate in the region between 50 cal kyr BP (δ 18O = 27.1‰) and 27 cal kyr BP (δ 18O = 34.0‰) was suggested based on the oxygen isotopic values found in the mammalian bone fossils, which presents similarity and good correlation with the oxygen isotopic values recorded in stalagmites from two caves in Brazil.

• The Brazilian case do not provide evidence that rises in wages squeezed markups. • Economic sectors pass on different sources of cost pressure asymmetrically to prices. • Attempts to increase competitiveness by cutting labor costs may be ineffective. • Measures to reduce service costs in the production process should be prioritized. This paper aims to empirically investigate the relationship between sectoral unit labor costs and markups for the Brazilian economy from 2000 to 2013. The underlying hypothesis is that labor costs are the sole determinant of a firm's competitiveness, a notion that has been widely accepted as conventional wisdom despite the lack of empirical evidence. Our analysis of the Brazilian economy does not provide evidence that the rises in wages squeezed markup rates over this period. Conversely, our study suggests that the compression of markups was influenced by a set of factors, including the costs of service sector inputs, stagnating labor productivity, and international trade pressure. Therefore, our study highlights the need for a more nuanced understanding of the relationship between unit labor costs and markups by shedding some light on the asymmetric impact of different sources of cost pressures and competition on sectoral markups in the Brazilian economy.

The politically motivated replacement in local governments is a pervasive fact in our modern democracies. Whether it has causal effects on the quality of public services, such as education, is a critical question and yet understudied. This paper uses a regression discontinuity design (RDD) for close elections to replicate Akthari, Moreira and Trucco (2022) who find negative effects on the quality of public education in Brazil (.05-.08 standard deviations of lower test scores). I first reproduce these main results, finding minor computational differences that have no effect on the conclusions. I also show that the estimates for Brazil are in general robust to different specifications following Brodeur, Cook and Heyes (2020). Finally, I implement the same RDD framework now applied to Chilean administrative records to find null effects on test scores. Taken together, these results suggest that political turnover has weakly negative effects on service quality. [ABSTRACT FROM AUTHOR]

• This paper aims to study the process of intergenerational income mobility in some Latin American economies (Brazil and Panama), which have been much neglected in the relevant literature. • Our rich and detailed dataset (the IPUMS survey) allows us to provide the most reliable estimates of intergenerational mobility, after controlling for a number of additional control variables which were unavailable in previous studies, such as family size, literacy level of fathers, and location in rural versus urban areas. • In the present study, we can also eliminate co-residence and young adults' problems which are widely discussed in the current literature. This allows us avoiding complex and problematic methodologies to predict the incomes of parents for the non-co-residing children from the co-residing children. • A major advantage of our paper as compared to the previous literature, considering that the instrumental variables typically used for this methodology do not fully satisfy the exclusion restriction. • We show that behind social immobility there is also a sluggish process of structural change and an insufficiently progressive tax system. This paper aims to study the process of intergenerational income mobility in some Latin American economies (Brazil and Panama), which have been much neglected in the relevant literature. Like other countries in the area, Brazil and Panama have a stagnant economy coupled with high income inequality. Our rich dataset allows us to provide the most reliable estimates of intergenerational mobility, after controlling for a number of additional control variables which were unavailable in previous studies. We provide estimates broken down for different genders, age groups, locations, education of fathers. Our results are robust to different specifications and suggest that previous studies significantly overrated the extent of the intergenerational mobility in the countries considered. However, our figures are still compatible with an extremely low degree of social mobility. Moreover, we show that behind social immobility there is also a sluggish process of structural change and an insufficiently progressive tax system. [ABSTRACT FROM AUTHOR]

The trade of elasmobranchs (sharks and rays) in Brazil threatens the country's rich endemic biodiversity. The present study explored the use of DNA-based tools to monitor the Brazilian elasmobranch trade, focusing on their role in identifying processed products and supporting conservation efforts. A systematic search of literature was conducted and included 35 peer-reviewed papers published between 2008 and 2023. A shift from the development of DNA-based tools to direct trade applications has been observed since 2015. Molecular identification challenges, including costly sequencing and limited resources in national databases, were identified along with proposed solutions, such as protocol optimization and exploration of cost-effective alternatives. Biases in trade analysis papers, particularly the lack of research in the Northeast Region of Brazil, and issues with sample sizes were evident. Species identified using DNA-based tools included the critically endangered Scalloped Hammerhead Shark (Sphyrna lewini), which appeared in 46 % of the evaluated papers, followed by the Blue Shark (Prionace glauca), and several others threatened species, such as the critically endangered and endemic Brazilian Guitarfish (Pseudobatos horkelii) and the recently categorized as vulnerable Sharpnose Shark (Rhizoprionodon porosus). Other species were reassessed by IUCN, including previously non-threatened species that are now at risk, emphasizing the need for fisheries management, trade monitoring and conservation measures. Our findings highlight the importance of continued genetic monitoring to analyze market trends and adjust legislation, encouraging compliance with frequent inspections to enhance wildlife conservation. We also identified gaps in research and recommended strategies for accurate species identification, broader investigation, and effective management. • Meta-analysis of DNA-based tools for monitoring trade, focusing on Brazil's elasmobranchs • Challenges in molecular identification were identified (e.g., limited database resources). • Brazil comprises 203 elasmobranch species, and 64 were molecularly detected in trade. • 83 % of species detected are threatened (IUCN), including recently updated assessments. • Ten research gaps were outlined, along with recommended practical solutions for future work.

This paper analyses the potential implications of the proposed European Union Deforestation Regulation (EUDR) and the recently adopted United Kingdom (UK) legislation on deforestation-free supply chains (henceforth 'the legislation') for different stakeholders in Brazil. These regulations intend to address global commodity-driven deforestation and forest degradation by ensuring that targeted commodities and products placed on (or exported from) markets are of minimal risk of being associated with - in the EU - deforestation and forest degradation or - in the UK - illegal deforestation. The paper examines potential compliance readiness in cattle, cocoa, coffee, palm oil, soybean and tropical timber supply chains in Brazil, indicating specific challenges that may arise. Through the construction of a "Compliance Likelihood Index", our research provides comparable indications to policymakers on sectors and stakeholders that may need stronger support to meet the requirements, in order to maintain Brazil's access to EU and UK markets. The paper indicates that coffee is the sector with the highest level of incentivization and smallest hurdles for compliance, while the cattle sector may face stronger challenges to rapidly adjust its production system towards a deforestation-free value chain and prove compliance. Results of our analysis also highlight the need for collaboration between the EU/UK and Brazil in order to promote alignment between domestic and demand-side legislations so that they are mutually reinforcing. Results of this exercise, which has a focus on the producer-country view of demand-side legislation, will contribute to discussions on the merits of different approaches to strengthen the governance of deforestation-risk commodity trade. [Display omitted] • Brazil's coffee sector may currently have the greatest likelihood of ready compliance. • Cattle may be the sector to which the regulations may pose the greatest challenges. • The EU and UK should focus on providing financial means and technical assistance for smallholders. • The EU and UK legislation will need to be accompanied by domestic policies and regulations in Brazil.

In this study, projections and current status of municipal solid waste generation worldwide and its collection, final destination, and waste-to-energy technologies are reviewed. Firstly, an overview of waste generation worldwide is presented comparing income levels and the material composition of residues in several regions. This paper focused on contrasting Brazil and Portugal in terms of waste production and its management from generation to disposal or treatment. Furthermore, it is presented a summary of leading waste-to-energy technologies such as incineration, anaerobic digestion, gasification, pyrolysis, co-combustion, co-gasification, among others. Technical aspects of these thermo-chemical, biological, and physic-chemical processes for the production of biofuels such as biogas, syngas, biodiesel, and hydrogen-enriched gases are presented. Additionally, current aspects of the waste-to-energy market are exposed regarding the major players, investments, and expectations for the future of this activity with the elaboration of SWOT analyses. Finally, a review of greenhouse gases emissions worldwide is presented, specifically from Brazil and Portugal, as well as some consequences of these pollutant gases on the society and the environment and which are the main technologies for carbon dioxide capturing and sequestration as promising solutions for lower pollutant gases concentration in the atmosphere. This review paper aims to provide information for the management of municipal solid waste in Brazil and Portugal considering the mutual objective of meeting sustainable development goals.

Recently, the Brazilian Ministry of Education issued New Curriculum Guidelines for engineering programs. This paper encompasses a pedagogical intervention reflecting our efforts to incorporate these new guidelines into our engineering program. Specifically, this work has led to the competency-based rework of the following subjects offered in the Chemical Engineering Undergraduate Program at the Federal University of São Paulo (Unifesp): I) Modeling and Systems Analysis; II) Synthesis and Optimization of Chemical Processes; III) Chemical Process Simulation; IV) Process Analysis and Control; V) Chemical Process Design; and VI) Chemical Installations Design. Thirteen transdisciplinary competencies are integrated throughout the six subjects. Students highlighted design thinking, lifelong knowledge/learning, openness to act autonomously, teamwork, communication, and cooperation as essential qualities. Moreover, the greater focus on the process systems engineering approach involving the analysis, synthesis, design, and control of sustainable processes helps chemical engineers to face new challenges using renewable resources. • Pedagogical intervention on competency-based versus subject-based development. • Competencies development in Process Systems Engineering subjects. • Reformulation of development by competencies is endorsed by sustainable development. • Functional competencies listed improve attitude, skills, and knowledge of students. • Transdisciplinarity solutions respecting the environment and next generations.

• Multifractal analysis of the Ionosphere Layer. • Intermittence in Ionosphere Layer. • Ionosphere Layer out-of-equilibrium. A digital ionosonde of the type known as Canadian Advanced Digital Ionosonde (CADI) is operational at Jatai ( 17.2 o S , 51.9 o W), Brazil. This ionospheric sounding station is located under the equatorial ionospheric anomaly crest. The F-layer electron density profile presents considerable day-to-day variability, even during the undisturbed conditions, and is still one of the less understood aspects of the physics of the ionosphere. The propagation of waves into the ionosphere may be playing an important role in this day-to-day ionospheric variability. In this paper we used the multifractal approach in order to understand the physical process underlying to rise to plasma bubbles. Results shown that the ionosphere layer is in out-of equilibrium, independent of the presence or not of the planetary waves (PW), equatorial plasma bubbles (EPBs) or another ones. Wavelet techniques are also used to investigate the action of these plasma bubbles over the planetary waves. [ABSTRACT FROM AUTHOR]

Over the past decades, microfinance has become a pillar of economic development policies. However, despite the great popularity of micro-credit programs, the results of empirical studies are mixed. Thus, more research is needed to help us understand how effective microfinance is in achieving poverty reduction, economic development, and financial inclusion. This paper contributes to the literature by relying on a unique dataset from one of the biggest Fintech companies in Brazil to study the impact of microcredit on small firms' outcomes. Using a difference-in-difference approach, we find that access to credit increases monthly revenues and profits by nearly 4.5%. We show that the effects are stronger for women-led businesses and less experienced entrepreneurs. In addition, we find that credit renewal strengthens the benefits of credit access. We discuss several policy implications from our results. In particular, the permanent availability of credit – as opposed to one-time/short-term interventions -- has greater potential to generate virtuous cycles of ever more reinvestment and growth, indicating larger gains from relaxing borrowing constraints in the long run.

• A human-jigger parasite system with control policies is established. • A time-optimal control problem with limited resources is proposed. • A numerical method combining the control parametrization scheme with the interior point algorithm is constructed. • A trade-off between the optimal eradication time and the effective funding is provided. Tungiasis, as an epidermal parasitic skin disease, leads to long-term injury and life threats to humans in resource-limited countries. In this paper, we aim to minimize the epidemic duration of tungiasis disease with limited resources. A human-jigger parasite system with four control policies for humans and jiggers is established. We propose a time-optimal control problem, in which the eradication time and limited resources are involved. By applying the Pontryagin's minimum principle, we prove that, only bang-bang controls are admitted for all the control policies. Furthermore, a numerical scheme combining the control parametrization scheme with the interior point algorithm is constructed. Finally, numerical simulations are carried out using actual data of humans and jiggers in Brazil. From all the results, we conclude that, there is a trade-off between the optimal eradication time and the effective funding; once the effective funding is properly used, the disease can be controlled effectively; strengthening personal protections, improving treatments for humans and making adulticiding efforts contribute to keeping humans away from the disease.

• Examines unique cases: wild burros in America; rewilded donkeys in Europe; street donkeys in Brazil. • Binary framings (e.g. wild/domestic) are inadequate for free-roaming donkeys. • Specifies the 'entangled autonomy' of F-R donkeys using a relational approach. • Builds on scholarship in wild animal geographies and feral political ecologies. • Research on F-R donkeys would benefit from natural and social science collaboration. For thousands of years, the donkey (Equus asinus) has played an essential role in human society, underpinning the earliest forms of civilisation, facilitating critical trade networks, contributing to agricultural development, construction and mining. However, with the rise of motorised transport and agricultural machinery, the donkey was gradually turned loose in many places, and left free to roam. The emergence of freeroaming donkey populations has brought novel challenges for conservationists, land managers and animal welfarists alike. As non-native species that live and breed independently in large numbers, free-roaming donkeys appear as an ambiguous indeterminate group of wild-domestic creatures that sit uneasily with rapidly changing landscapes, societies and economies. This paper explores the status of free-roaming donkeys and the ongoing tension between the wild and the domestic, including the binary thinking underpins it and produces donkeys as non-native or 'out of place'. Using a relational approach and paying attention to the various ways in which freeroaming donkeys are entangled and embedded within cultural historical landscapes, this paper suggests how donkeys might be re-examined in terms of their 'entangled autonomy', building on recent interventions in 'wild' animal geographies and 'feral' political ecologies. In doing so, it reframes the debate around the status of freeroaming donkeys and posits an argument for how they might be considered to 'belong' or have legitimacy within these landscapes, suggesting that more attention needs to be given to the spaces and places that donkeys create or contribute to, as well as those they disrupt and challenge.

Background: The violent behavior of football fans is constantly associated with their drinking habits. Aiming to reduce its impact, policy makers often ban the sales and consumption of alcohol beverages during matches. Nonetheless, there are few papers that empirically analyzed such relationship, and our paper aims to shed light on this question. Methods: Out dataset comprises 4,560 matches from the first and second tiers of the Brazilian League, where 245 exhibited at least one antisocial behavior from fans. Ordered logistic regressions are used as method. Results: Our empirical findings evidence that the sales of alcoholic drinks do increase the likelihood of severe antisocial behavior. We also observed a higher likelihood of violent cases when the home club loses its match as well as during crowded matches. Conclusions: We conclude that the change in the alcohol police in Brazil did show a significant association with the likelihood of antisocial behavior among football fans. However, since the magnitude of such effect is small, further research is needed to examine the potential benefits of this policy change. [ABSTRACT FROM AUTHOR]

Energy simulations are extensively employed by researchers and designers to assess strategies aimed at enhancing the thermal performance or energy efficiency of buildings. However, the methodologies for conducting these simulations and analyzing their outcomes vary according to regional standards and among research groups. This work aims to investigate the methods for evaluating the thermal performance of buildings through energy simulations, through a systematic literature review. Initially, the authors surveyed articles published between 2011 and 2022 on Scopus and Web of Science. From an initial pool of 1463 articles that met the research criteria, a refined list of 158 papers were read completely. The authors examined prevalent trends in the methods and identified future research directions. Most publications originated from authors in Northern Hemisphere, with only Brazil showing expressive numbers in the Southern Hemisphere. The results revealed the three most employed methods: Thermal Load (94 %), Degree-Hour (or Degree-Day) (9 %), and Design Days (5 %). EnergyPlus stands out as the widely preferred software (65 % of studies), and 62 % of them incorporate some form of validation or calibration. Articles often lack complete simulations parameters and/or clarity in their presentation. In response to the identified gaps, this study introduces a checklist of best practices for presenting the simulation steps. As such, this work serves as a valuable theoretical framework for future assessments of building thermal performance through computer simulation. • We reviewed 185 papers on methods to evaluate therm. Perform. Via energy simulations. • Thermal Load (94 %), Degree-Hour (9 %) and Design Days (5 %) are the most used methods. • EnergyPlus and ASHRAE are the most used software and standard, respectively. • Literature gaps include comparative studies and conversion strategies among methods. • Standardized protocols for model calibration and validation are still limited.

The United Nations Decade of Ocean Science for Sustainable Development, aka Ocean decade (OD), was established with the slogan "The ocean we need for the future we want''. This great effort aims to strengthen the knowledge, health and management of the ocean, as well as to articulate various organizations, public and private entities involved in this matter. Established in the Ocean Decade Implementation Plan, the Ocean Decade Challenges (ODCs) represent the immediate priorities for the OD. Although OD national strategies already integrate different agencies and organizations, it is often done without a full consideration of existing knowledge from different national management programs and tools. This paper reviews the existing opportunities from Brazil's governance system that can contribute to ODCs. To carry out this investigation we applied the Decalogue for Coastal Management (DCM), which is recognized as a framework for describing key aspects of a public management system. Our analysis indicates that the country is taking actions linked to all of the ODCs, in which the ODC 2, 9 and 10 are the ones with better scores, and ODC 3 and 7 with lower scores. In the DCM analysis, Brazil showed strong policy and management tools that contribute to the ODCs, with relevant capacity building initiatives. In contrast, citizen participation and economic resources were key limiting aspects. While Brazil has many initiatives that deal with ODCs issues, the lack of integration and coordination can be a great challenge to overcome in the OD actions. Our paper highlights the need to integrate data and knowledge, advance transparency, and the importance of implementing policy into the management process. [ABSTRACT FROM AUTHOR]

This paper discusses the disappointing outreach of Brazilian urban reform by analyzing the underlying tensions and contradictions of its key principle, that is, the social, function of property (SFP), from a perspective of contemporary theoretical debates on the double nature of rent (i.e., related to monopoly positions and emerging from market, circulation). The SFP principle is grounded in anti-rentier, agrarian reform thinking, which stressed that individual monopoly landowners should not be allowed to retain their property for speculative purposes and use it productively to increase food supplies. In contemporary dense cities, however, using property "productively" implies redevelopment, that is, transformation of existing structures of the built environment, into alternative ones. This has two implications, one related to the essence of the SFP, (its being), the other regarding what it means having a SFP in an urban setting. In relation to the former, despite its anti-rentier stance, in cities the SFP triggers a redevelopment-rent nexus due to the circulation of rents in non-competitive markets. Regarding the latter implication, having a SFP in cities requires complex, open-ended and utilitarian negotiations between state and non-state actors aimed at the appropriation of rents to articulate the conflicting interests of individual property owners with the collective good. The theoretical argument of the paper is illustrated with a short, heuristic case on redevelopment in the city of São Paulo, while its conclusion provides elements for a research agenda on the limits of market-based, reformist versus right- based planning beyond this specific context.

Climate change has increased the frequency of extreme weather events and, consequently, the number of occurrences of natural disasters. In Brazil, among these disasters, floods, flash floods, and landslides account for the highest number of deaths, the latter being the most lethal. Bearing in mind the importance of monitoring areas susceptible to disasters, the REMADEN/REDEGEO project of the National Center for Monitoring and Natural Disaster Alerts (Cemaden) has promoted the installation of a network of soil moisture sensors in regions with a long history of landslides. This network was used in the present paper as a base to develop a system for moisture forecasting in those critical zones. The time series of rainfall and moisture were used in an inversion algorithm to obtain the geotechnical parameters of the soil. Then the geotechnical model was used in a forward calculation with the rainfall prediction to obtain the soil moisture forecast. The landslide events of March 2020 and May 2022 in Guarujá and Recife, respectively, were used as study cases for the developed system. The obtained results indicate that the proposed methodology has the potential to be used as an important tool in the decision-making process for issuing landslide alerts. • This paper presents a novel system aimed at predicting soil moisture conditions based on rainfall forecast data.

The Cancer Intervention and Surveillance Modeling Network (CISNET) Lung Working Group age-period-cohort methodology to study smoking patterns can be applied to tackle important issues in tobacco control and public health. This paper summarizes the analyses of smoking patterns in the U.S. by race/ethnicity, educational attainment, and family income and for each of the 50 U.S. states using the CISNET Lung Working Group age-period-cohort approach. We describe how decision makers, policy advocates, and researchers can use the sociodemographic analyses in this supplement to project state smoking trends and develop effective state-level tobacco control strategies. The all-cause mortality RR estimates associated with smoking for U.S. race/ethnicity and education groups are also discussed in the context of research that measures and evaluates health disparities. Finally, the application of the CISNET Lung Working Group age-period-cohort methodology to Brazil is reviewed with a view to how the same types of analyses can be applied to other low- and middle-income countries.

This paper examines the impacts of emergency cash-transfers on individuals' social distancing behaviour and beliefs about COVID-19. We focus on the impacts of "Auxilio Emergencial" (AE): a large-scale cash-transfer in Brazil targeting low-income individuals who were unemployed or informally employed during the pandemic. To identify causal effects we exploit exogenous variation, arising from the AE design, in individuals' access to the cash-transfer programme. Using data from an online survey, our results suggest that eligibility to the emergency cash transfer led to a reduced likelihood of individuals contracting COVID-19, likely to have been driven by a reduction in working hours. Moreover, the cash transfer seems to have increased perceptions about the seriousness of coronavirus, while also exacerbating misconceptions about the pandemic. These findings indicate effects of emergency cash-transfers in determining individuals' narratives about a pandemic, in enabling social distancing and potentially in reducing the spread of the disease.

• The Brazilian economy's lack of dynamism has coincided with China's rise as a global powerhouse. • This is why we have evaluated if an increase in China´s market share in a third country's market is associated with an increase or a decrease of Brazil´s market share. • Our results suggest that Chinese manufacturing exports directly displaced Brazilian exports. • The Real's appreciation in the 2000s was an indirect transmission channel. This paper analyses the relationship between Brazil´s regressive specialisation and China´s increased international competitiveness. The Brazilian economy's lack of dynamism and competitiveness in global markets, particularly when it comes to the production and exportation of manufactured goods, has coincided with China's rise as a global powerhouse. This is why we have considered whether an increase in China´s market share in a third country's market is associated with an increase or decrease in Brazil´s market share. To test this relationship, we applied a generalised method of moments (IV-GMM) in a panel data framework. Our main results suggests that: (i) China´s market share increases were associated with decreases in Brazil´s share; and (ii) the effect of Chinas´ market share can change according to the size of the partner's economy. Finally, we have explored the implications of our findings considering Keynesian and structuralist theories, which highlight the importance of the manufacturing sector. [ABSTRACT FROM AUTHOR]

[Display omitted] • New tool, Circular Flow, tackles the lack of consistency in measuring circularity. • Circular Flow provides quantitative results for energy and material flows. • Circular Flow can be applied in any sector/system with material and/or energy flows. • Novel visual representation helps to spot opportunities for internalizing value. • A case study in a Brazilian agroindustrial cooperative was performed. Unlike the linear model "take-make-use-dispose", the circular economy model "grow-make-use-restore" intends to potentiate material and energy flows within a system with the premise of increasing environmental gains. Moreover, circular economy practices can be alternatives for closing loops in companies from different sectors, with material-, waste-, and energy-related initiatives towards promoting greater internal value-adding. However, the lack of consistent tools for measuring circularity of processes and companies is a gap yet to be covered. To tackle this gap, this paper's aims are: (i) to build a new tool, called Circular Flow, for generating greater internal value and competitive advantage in organizations and identify potential circular economy-related opportunities for closing loops based on external flows, (ii) to apply the tool in a case study, an organization that presents material and energy (electricity) flows and exchanges with other organizations, and (iii) to discuss the integration and potential opportunities for the tool in organizations. The novel, Circular Flow, tool is based on a set of circular graph visualizations, and quantitative circularity indicators. For the graphical visualization, the software tool R (using the Circlize package) was used. The graphs aid the visualization of several interconnected pieces of information, allowing to show all quantitative flows of inputs and outputs, intuitively showing the paths (origin and destination of each flow) within the boundaries of the system under study. The quantitative indicators, e.g. Circularity of the organization (Circ p) and Circularity of each process (Circ o), show a circularity index ranging from 0% to 100%, which can be assessed at different levels. The criteria to select these indicators are based on quantities of inputs and outputs regarding mass and electricity. The tool has been applied in a case study of a rural property in southern Brazil, which region holds a tradition for milk and pig farming. The use of the tool showed the involvement of the rural property with its neighbors and with an agroindustrial cooperative. Keeping these flows within the system may increase environmental gains by reducing transportation, using renewable sources of energy, reducing costs, and boosting the generation of jobs and income in the region due to new market opportunities and business models.

• Development of a fault detection algorithm on aIRT images highlighting its main challenges, shortcomes, and workarounds; • Utilization of an orthomosaic reconstruction software package describing the challenges that the workflow impose for the automatic fault detection algorithms; • Evaluation of the impact of different flight configurations and dataset on the processing time and results; • Application of the proposed framework in real cases, evaluating the challenges imposed by real datasets. As large-scale Photovoltaic (PV) power plants are being expanded in installation number and capacity, aerial infrared thermography (aIRT) has proven to be effective in detecting at different phases of their development, construction and commissioning to operation and maintenance. However, evaluating the aerial imagery over hundreds of hectares fields of PV arrays is very time-consuming and subject to human error. This paper proposes a complete framework for automatically detecting faults in large-scale PV power plants and their physical location inside the plant site. To this end, a Mask-RCNN algorithm is developed and fine-tuned for instance segmentation using a dataset of 93 samples collected in an aIRT flight campaign in Brazil. The results are combined with orthomosaic techniques to create an orthomap of the PV system with the highlighted faults. The proposed method has been tested to automatically detect the faults in two power plants. Several tests were performed to improve the algorithm's accuracy, resulting in high-accuracy results for detecting and localizing hot spots in PV plants and disconnected substrings. The resulting maps could successfully show the location of these faults with high accuracy (10% of false positives). [ABSTRACT FROM AUTHOR]
