Salinity determinations are usually made indirectly, measuring electrical conductivity, which depends on salinity and temperature. Unusual conductivity and salinity are indicative of pollution, regardless anthropogenic or natural sources. Aquatic species adapt to specific salinity levels. If this level is altered, it can result in the death of them, because there are changes in the oxygen concentrations. The goal of this work is the development of a low cost, high autonomy inductive salinity sensor to integrate into a sensor network for water column measurement from estuaries to deep ocean applications., This work is co-funded by the projects SONDA (PTDC/EME-SIS/1960/2020), ATLÂNTIDA (NORTE-01-0145-FEDER-000040) and CMEMS R&D centre - UIDB/04436/2020.

Na última década, os μplásticos tornaram-se um dos principais problemas de poluição nos oceanos, cursos de água e rios, atraindo atenção devido aos efeitos nocivos que provocam no meio ambiente e na saúde. Os métodos atuais para quantificação de μplásticos incluem imagiologia hiperespectral, espectroscopia de Raman e espectroscopia de infravermelho por transformadade Fourier (FTIR). No entanto, estes equipamentos são volumosos, dispendiosos e requerem pessoal altamente treinado pelo que não podem ser aplicados para deteção in-situ.Este sensor visa revolucionar o paradigma das estratégias portáteis e in-situ para deteção de μplásticos, baseado em Lab-on-a-chip (LoC) e optoacústica em infravermelho (IR) num único dispositivo. Propõe-se uma plataforma com multissensores LoC para colocação massiva em ambientes subaquáticos para identificação e quantificação μplásticos in-situ. Cada dispositivo deve ser preciso, portátil, autónomo, barato e de fácil operação.

Robust wireless communication networks are a cornerstone of the modern world, allowing data to be transferred quickly and reliably. Establishing such a network at sea, a Maritime Internet of Things (MIoT), would enhance services related to safety and security at sea, environmental protection, and research. However, given the remote and harsh nature of the sea, installing robust wireless communication networks with adequate data rates and low cost is a difficult endeavor. This paper reviews recent MIoT systems developed and deployed by researchers and engineers over the past few years. It contains an analysis of short-range and long-range over-the-air radio-frequency wireless communication protocols and the synergy between these two in the pursuit of an MIoT. The goal of this paper is to serve as a go-to guide for engineers and researchers that need to implement a wireless sensor network at sea. The selection criterion for the papers included in this review was that the implemented wireless communication networks were tested in a real-world scenario., cofunded by the project K2D: Knowledge and Data from the Deep to Space with reference POCI-01-0247-FEDER-045941, cofinanced by the European Regional Development Fund (ERDF), through the Operational Program for Competitiveness and Internationalization (COMPETE2020), and by the Portuguese Foundation for Science and Technology (FCT) under the MIT Portugal Program.

Facial expression facilitates the understanding of the individual's identity, being essential for communication and interaction in modern society. When this expression is limited, in addition to the functional consequences of the organism, it also has psychological and social consequences. The ARTHUR project developed a virtual surgery solution, applied to the bone and dental structure, capable of predicting the real impact on the patient's face mask. The solution is based on cloud and allows the clinical body to perform the virtual surgical planning, using cutting guides and plates or surgical guide lines, in a parameterized anatomical model of the head achieved through the fusion of three exams: TAC (CBCT), Intraoral Scan and 3D Stereo Photogrammetry. Above all, it is intended that, based on this planning and thanks to the parameterized anatomical model, it is possible to realistically forecast and represent the impact of the surgical intervention on the patient's face mask. This tool acts in different situations that require facial reconstruction, however this project focuses specifically on two types of use cases: bone congenital disfigurement and acquired disfiguration such as oral cancer with bone attainment. It is intended to be an intuitive and user friendly tool, which allows its use by less specialized technicians who can demonstrate the final results directly to the patient in the office. Able to predict visual impact with high realism and degree trust, will enable patients to participate more actively in the decision-making process therapy. H2020 - Copromoção published

The ARTHUR project consists of a platform that allows the virtual performance of maxillofacial surgeries, offering, in a photorealistic concept, the possibility for the patient to have an idea of the surgical changes before they are performed on their face. For this, the system brings together several image formats, dicoms and objs that, after loading, will generate the bone volume, soft tissues and hard tissues. The system also incorporates the patient's stereophotogrammetry, in addition to their data and clinical history. After loading and inserting data, the clinician can virtually perform the surgical operation and present the final result to the patient, generating a new facial surface that contemplates the changes made in the bone and tissues of the maxillary area. This tool acts in different situations that require facial reconstruction, however this project focuses specifically on two types of use cases: bone congenital disfigurement and acquired disfiguration such as oral cancer with bone attainment. Being developed a cloud based solution, with mobile support, the tool aims to reduce the decision time window of patient. Because the current simulations are not realistic or, if realistic, need time due to the need of building plaster models, patient rates on decision, rely on a long time window (1,2 months), because they don’t identify themselves with the presented surgical outcome. On the other hand, this planning was performed time based on average estimated values of the position of the maxilla and mandible. The team was based on averages of the facial measurements of the population, without specifying racial variability, so the proposed solution was not adjusted to the real individual physiognomic needs. in publication

R E S U M O Os objetivos do estudo são identificar o conhecimento acerca das inovações tecnológicas de sustentabilidade ambiental entre os atores de Instituição de Ensino Superior (IES) da área de saúde, estabelecer como se dá a utilização de tecnologias de substituição de recursos não renováveis no cotidiano e investigar os benefícios da utilização de tecnologias de substituição de recursos não renováveis para a sustentabilidade ambiental. Desde a revolução industrial, desenvolveu-se na sociedade uma preocupação emergente com a preservação ambiental e a sustentabilidade. A ideia de que as companhias se tornassem cada vez mais responsáveis pelos impactos de toda a cadeia produtiva tomou cada vez mais consistência e se expandiu para os consumidores, constituindo desse modo, um ideal que perdura até a atualidade. O Instituto Brasileiro de Geoestatística (IBGE) avaliou, em 2012, que no país são geradas aproximadamente 62.730.096 toneladas de resíduos urbanos por ano, sendo que destes, cerca de 6,2 milhões de toneladas são descartados de forma inadequada, gerando consequências, incluindo o processo saúde-doença. A educação para um descarte correto é de relevante importância, porém, recentemente, a utilização de tecnologias de substituição surge como opção no cotidiano da população. Pelo exposto, faz-se necessário abordar essa temática nos cursos da área da saúde, possibilitando a conscientização dos futuros profissionais, docentes e colaboradores das instituições formadoras. Trata-se de pesquisa com abordagem quantitativa, por meio do método exploratório-descritivo. Foram 100 participantes de uma IES privada da cidade de Curitiba. A coleta dos dados ocorreu por meio de questionário inserido em plataforma eletrônica online, cujo link foi enviado em uma rede social de comunicação já existente na instituição, nos meses de agosto a setembro de 2020. Os resultados demonstraram que os participantes compreendiam as classificações dos resíduos sólidos e impacto ambiental do uso excessivo dos plásticos. A maioria tem conhecimento das tecnologias de substituição e faz uso em seu cotidiano. Deste modo, torna-se essencial o desenvolvimento e implantação de projetos de educação ambiental eficazes e que resultem na construção de um senso crítico coletivo de preservação ambiental, muitas vezes não de forma imediata, mas que pode ser aplicado com pequenas atitudes cotidianas.

Technologies for the substitution of non-renewable resources in a higher education institution in health A B S T R A C T The objectives of the study are to identify the knowledge of technological innovations of environmental sustainability among the actors of the Higher Education Institution (HEI) in the health area, to establish how the use of non-renewable resource technologies occurs in everyday life and to investigate the benefits the use of technologies to replace non-renewable resources for environmental sustainability. Since the industrial revolution, you have become an emerging concern in society with environmental preservation and sustainability. The idea that companies become more and more responsible for the impacts of the entire production chain takes on more and more consistency and has expanded to consumers, thus constituting an ideal that lasts until today. The Brazilian Institute of Geostatistics (IBGE) evaluated, in 2012, that approximately 62,730,096 tons of urban waste are generated in the country per year, of which approximately 6.2 million tons are disposed of inappropriately, generating consequences, including the health-disease process. Education for correct disposal is of relevance, however, recently, the use of substitution technologies as a non-daily option for the population. From the above, it is necessary to address this theme in courses in the health area, enabling the awareness of future professionals, teachers and employees of training institutions. This is research with a quantitative approach, using the exploratory-descriptive method. There were 100 participants from a private HEI in the city of Curitiba. Data collection takes place by filling in an online electronic platform, the link of which was sent on a social communication network already existing at the institution, in the months from august to september 2020. The results showed that the participants understood as waste classifications solids and environmental impact of excessive use of plastics. Most are aware of replacement technologies and use them in their daily lives. Thus, it is essential to develop and implement effective environmental education projects, which results in the construction of a collective critical sense of environmental preservation, often not immediately, but which can be distributed with small daily attitudes.

Background: Although non-ischemic troponin elevation is frequently seen in patients admitted to the emergency department (ED), consensus regarding its management is lacking. Objectives: This study aimed to characterize patients admitted to the ED with non-ischemic troponin elevation and to identify potential mortality predictors in this population. Methods: This retrospective observational study included ED patients with a positive troponin test result between June and July of 2015. Patients with a clinical diagnosis of acute coronary syndrome (ACS) were excluded. Data on patient demographics and clinical and laboratory variables were extracted from medical records. Follow-up data were obtained for 16 months or until death occurred. The statistical significance level was 5%. Results: Troponin elevation without ACS was found in 153 ED patients. The median (IQR) patient age was 78 (19) years, 80 (52.3%) were female and 59(38.6%) died during follow-up. The median (IQR) follow-up period was 477(316) days. Survivors were significantly younger 76 (24) vs. 84 (13) years; p=0.004) and featured a higher proportion of isolated troponin elevation (without creatine kinase or myoglobin elevation) in two consecutive evaluations: 48 (53.9%) vs. 8 (17.4%), p

The aim of this study was to evaluate the chemical composition, digestibility, gas production kinetics and in vitro methane (CH4) production of Urochloa brizantha cv. Marandu under two stocking methods over three consecutive stocking cycles. The stocking methods were (1) a fixed-time stocking cycle of 33 days (33-SC) with a 30-day rest period and a 3-day grazing period, and (2) a variable stocking cycle, with the end of the rest period when the canopy intercepted 95% of the light and a 3-day grazing period (95-LI). The average rest period was 24.5-day (standard deviation of 5.2-day) for 95-LI. The in vitro dry matter digestibility (IVDMD) was higher (p < .01) for 95-LI (646 g/kg) relative to 33-SC (628 g/kg). Crude protein concentration was higher (p < .01) for 95-LI (154 g/kg) relative to 33-SC (136 g/kg). The ADF (303 g/kg DM) and aNDF (623 g/kg) were higher (p < .01) for 33-SC compared to 95-LI (287 and 605 g/kg respectively). The gas production potential from non-fibrous carbohydrates was 9.4% higher for 33-SC. The in vitro CH4 production per unit of degraded dry matter (DDM) was higher (p < .01) for 33-SC (19.9 CH4 ml/g), compared to 95-LI (17.9 CH4 ml/g). The 33-SC management resulted in rest periods that were too long for the time needed for optimal regrowth. The variable SC based on the 95-LI was more favourable, because it resulted in maximum yield of dry matter with improved forage nutritive value, while decreasing CH4 yield.

Determining the harvest date of table grapes is very important to achieve high-quality bunches with adequate soluble solids content, low titratable acidity, and high concentrations of polyphenols. Table grape consumption has increased worldwide due to its phenolic compound content and its beneficial effects on human health. Thus, this study aimed to characterize the phenolic ripening of ?BRS Vitoria? seedless table grapes at different ripening stages using HPLC?DAD?ESI-MS/MS. For this purpose, a trial was carried out during 2016 in a commercial vineyard of ?BRS Vitoria? seedless grape located in Marialva, state of Parana (Southern Brazil). Berry samples were assessed weekly, starting at v ́eraison until full ripeness. At each ripening stage, the berries were analyzed to determine their physicochemical characteristics and polyphenolic profile. It was observed that ?BRS Vitoria? grapes can be harvested approximately 28 days after v ́eraison, when the berries reach soluble solids content higher than 15◦Brix and low titratable acidity. The grapes presented a typical anthocyanin profile of hybrid grapes, composed of 3-glucoside and 3,5-diglucoside derivatives. In addition, pelargonidin traces were also observed, and this aglycone is rarely detected in grapes. The total anthocyanin concentration, as malvidin-3,5- diglucoside equivalents, is close to 596.9 mg kg Made available in DSpace on 2020-12-17T09:02:30Z (GMT).

Beliefs, expectations and values are often assumed to drive decisions about climate change adaptation. We tested hypotheses based on this assumption using survey responses from 508 European forest professionals in ten countries. We used the survey results to identify communication needs and the decision strategies at play, and to develop guidelines on adequate communications about climate change adaptation. We observed polarization in the positive and negative values associated with climate change impacts accepted by survey respondents. We identified a mechanism creating the polarization that we call the 'blocked belief' effect. We found that polarized values did not correlate with decisions about climate change adaptation. Strong belief in the local impacts of climate change on the forest was, however, a prerequisite of decision-making favoring adaptation. Decision-making in favor of adaptation to climate change also correlated with net values of expected specific impacts on the forest and generally increased with the absolute value of these in the absence of 'tipping point' behavior. Tipping point behavior occurs when adaptation is not pursued in spite of the strongly negative or positive net value of expected climate change impacts. We observed negative and positive tipping point behavior, mainly in SW Europe and N-NE Europe, respectively. In addition we found that advice on effective adaptation may inhibit adaptation when the receiver is aware of effective adaptation measures unless it is balanced with information explaining how climate change leads to negative impacts. Forest professionals with weak expectations of impacts require communications on climate change and its impacts on forests before any advice on adaptation measures can be effective. We develop evidence-based guidelines on communications using a new methodology which includes Bayesian machine learning modeling of the equivalent of an expected utility function for the adaptation decision problem.

AIMS: To assess stroke rate after transcatheter mitral valve repair (TMVR) with MitraClip, comparing it with surgical mitral valve repair (SMVR) and optimal medical treatment (OMT). METHODS AND RESULTS: We systematically searched PubMed, Embase and Cochrane Controlled Register of Trials, in December 2018, for studies comparing TMVR with SMVR and/or OMT for the treatment of severe mitral regurgitation. Random-effects and cumulative meta-analysis was performed. Ten studies were included: seven of TMVR versus SMVR and three of TMVR versus OMT, providing a total of 1881 patients and 61 pooled strokes (16 in TMVR versus SMVR and 45 in TMVR versus OMT). There was no difference in stroke incidence between TMVR and SMVR (pooled OR 0.49 [0.17, 1.42], P=0.19). Cumulative meta-analysis showed a significantly lower stroke rate in TMVR, compared to SMVR (OR 0.4 [0.24, 0.67], P< 0.01). For TMVR versus OMT, no difference in stroke rate was identified (pooled OR 1.09 [0.60, 1.97], P=0.79). Post-procedure de novo atrial fibrillation was more frequent in SMVR when compared with TMVR. CONCLUSIONS: Although with a low number of pooled events, there was a trend for a lower post-procedure stroke in TMVR when compared with SMVR and a similar one between TMVR and OMT alone. info:eu-repo/semantics/publishedVersion

A inserção de novas tecnologias aplicadas ao ensino além de tornar as disciplinas mais atrativas, desenvolve o raciocínio lógico e mostra a aplicabilidade dos conceitos estudados. O eletromagnetismo tem suas múltiplas aplicações pouco exploradas no ensino praticado na maioria das escolas devido à alta complexidade e abstração do conteúdo. Assim, o aluno apresenta dificuldades para estabelecer relações entre o que é ensinado na sala de aula e suas aplicabilidades no cotidiano. Neste contexto, destaca-se possível e vantajosa a utilização de softwares de simulação computacional, com os quais se torna possível desenvolver algoritmos, além de idealizar e representar problemas clássicos do eletromagnetismo. Neste trabalho, é apresentada uma proposta de ensino de Eletromagnetismo utilizando o software Quickfield Student. Destaca-se que se trata de resultado preliminar de trabalho. A sua aplicabilidade até este momento é validada por meio de simulações envolvendo a Lei de Coulomb e capacitores cilíndricos. São realizadas análises qualitativas, que envolvem a conformidade com o comportamento teórico do problema físico, e quantitativas, que analisa os valores obtidos em simulação e de forma analítica. Os resultados obtidos são satisfatórios, apesar da ocorrência de erros devido à limitação da versão utilizada.

Este trabalho tem como objetivo apresentar o desenvolvimento de um protótipo de uma estufa automatizada utilizando o microcontrolador Arduino. A estufa controla e mede os parâmetros de temperatura e luminosidade e mede umidade em seu interior. Os parâmetros a serem controlados podem ser especificados pelo usuário. No caso da temperatura, pode-se definir a temperatura mínima e máxima na estufa dentro da faixa de 23oC e 32oC, respectivamente. Para a luminosidade, o controle é feito de acordo com o horário do dia, também pré-determinada pelo usuário. Quando a temperatura está diferente da estipulada pelo usuário, um sistema de aquecimento ou ventilação é acionado em conjunto com um alerta visual na tela do display utilizado. A cada ajuste de temperatura os dados são armazenados na memória EEPROM. A elaboração deste trabalho permitiu adicionar recursos inteligentes a uma estufa, proporcionando ao usuário dados armazenados e acionamento automatizado que comumente não é disponível nas estufas tradicionais.

Article In developing countries such as Brazil, research on low-cost remote sensing and computational techniques become essential for the development of precision agriculture (PA), and improving the quality of the agricultural products. Faced with the scenario of increasing production of emerald grass (Zoysia Japônica) in Brazil, and the value added the quality of this agricultural product. The objective of this work was to evaluate the performance of RGB (IV) vegetation indices in the identification of exposed soil and vegetation. The study was developed in an irrigated area of 58 ha cultivated with emerald grass at Bom Sucesso, Minas Gerais, Brazil. The images were obtained by a RGB digital camera coupled to an remotely piloted aircraft. The flight plan was setup to take overlapping images of 70% and the aircraft speed was 10 m s -1 . Six RGB Vegetation index (MGVRI, GLI, RGBVI, MPRI, VEG, ExG) were evaluated in a mosaic resulting from the images of the study area. All of the VIs evaluated were affected by the variability of lighting conditions in the area but MPRI and MGVRI were the ones that presented the best results in a qualitative evaluation regarding the discrimination of vegetation and soil.

The number of falls is growing as the main cause of injuries and deaths in the geriatric community. As a result, also the cost of treating the injuries associated with falls is increasing. Thus, the development of fall detection and prediction systems with the capability of real-time monitoring without user restriction is imperative. For this reason, canes can be a great choice to embed fall-related systems. This paper aims to achieve a complete state-of-the-art concerning the development of fall detection and prediction algorithms implemented in canes. In order to accomplish this goal, a comprehensive search was performed. This search includes the IEEE, Scopus and Web of Science databases regarding developed systems in the literature. Also, a commercial search on Google and a patent search on Espacenet and the United States Patent and Trademark Office was performed. To this day, it has not been developed any type of cane related system which focuses on the temporal window preceding a fall and that accesses the risk of falling, even though a considerable amount of fall detection systems have already been presented., This work has been supported by the FCT - Fundação para a Ciência e Tecnologia - with the scholarship reference PD/BD/141515/2018, by the FEDER funds through the COMPETE 2020 - Programa Operacional Competitividade e Internacionalização (POCI) and P2020 with the Reference Project EML under Grant POCI-01-0247-FEDER-033067, and through the COMPETE 2020 POCI with the Reference Project under Grant POCI-01-0145-FEDER-006941.

This paper presents a novel lab-on-a-chip (LOC) device for seawater pH quantification based on spectrophotometric methods. The device integrates optical, electronics and microfluidic systems, providing an autonomous, compact and portable platform for in-situ, long-term and low-cost seawater pH measurements. The developed system was validated in laboratory with measurement of various seawater samples, of different pH, within the seawater pH interval (7.50-8.30). The response of the LOC shows a high reproducibility and stability with a resolution of 0.01 pH units. Thus, the device has a high potential to be use in moored oceanic applications., This publication/presentation was financed by FCT with the reference project UID/EEA/04436/2013, by FEDER funds through the COMPETE2020– Programa Operacional Competitividade e Internacionalização (POCI) with the reference project POCI-01- 0145-FEDER- 006941 and the work was funded by Programa Operacional Regional do Norte (NORTE2020), through Fundo Europeu de Desenvolvimento Regional (FEDER), Project NORTE-01-0145-FEDER-000032 – NextSea.

The influence of substrate type in boosting thermoelectric properties of co-evaporated Bi2Te3 and Sb2Te3 films (with 400 nm-thick) is here reported. Optimized power factor values are 2.7 × 10−3 W K−2 m−1 and 1.4 × 10−3 W K−2 m−1 for flexible Bi2Te3 and Sb2Te3 films, respectively. This is an important result as it is at least 2 times higher than the power factor found in the literature for flexible Bi2Te3 and Sb2Te3 films. A flexible infrared thermopile sensor was developed with high detectivity (2.50 × 107 cm √HzW−1)., This work is supported by FCT with the reference project UID/EEA/04436/2013, by FEDER funds through the COMPETE 2020—Programa Operacional Competitividade e Internacionalização (POCI) with the reference project POCI-01-0145-FEDER-006941.

Background: Considering the prevalence of denture stomatitis and the challenge of controlling this pathology using conventional therapies, natural products have been suggested as important therapeutic alternatives due to their an tifungal and anti-biofilm properties. Thus, this study investigated if immersion in Terminalia Catappa Linn. extract (TCE) affects Candida albicans biofilms developed on denture acrylic resin discs. Material and Methods: The minimal inhibitory and minimal fungicidal concentrations (MIC and MFC, respecti vely)tests were performed for TCE against suspensions of C. albicans. For the biofilm assay, discs (10 x 2 mm) were fabricated using a denture acrylic resin with surface roughness standardized. The biofilms were allowed to de velop for 24 hours. Then, they were immersed in the following treatments overnight (8 hours): phosphate-buffered saline (PBS, control), TCE at MIC, 5XMIC or 10XMIC. The biofilms were analyzed for cell counts and microsco py. Data were analyzed by ANOVA followed by a Tukey test at a 5% significance level. Results: The minimal concentration of TCE required to inhibit C. albicans was 6.25 mg/mL, while MFC was 12.5 mg/mL. Immersion in TCE at MIC was sufficient to reduce 80% of the biofilm viable cells compared to the control group (p < 0.001). Microscopic images confirm that immersion at 5XMIC and 10XMIC had a fungicidal activity with no significant differences between the concentrations regarding viable cells counts (p > 0.05). Conclusions: Within the limitations of this study, it was possible to conclude that immersion in TCE reduced the C. albicans biofilms cells developed on the denture acrylic surface Introdução: Considerando a prevalência da estomatite protética e o desafio de controlar esta patologia com terapias convencionais, os produtos naturais têm sido sugeridos como importantes alternativas terapêuticas devido às suas propriedades antifúngicas e antibiofilme.

One of the main problems of urban road networks is the imbalance between supply and demand associated with the massive use of motorized transport, which leads to frequent traffic congestion in sensitive areas and structuring road axes of these territories. This phenomenon is one of the causes of increased levels of noise and pollution and lack of road safety in urban centers that directly affect the quality of life of populations. In order to study the impact of several changes in the road network and transportation system of the city of Guimarães, this article presents the procedure for modeling and allocating traffic to the city's road network through the use of PTV Visum software. In this context a possible conclusion of the ring road - main arterial route of the city, by the slope of Monte da Penha, was studied for the morning and afternoon peak hours. In order to carry out this study, the Origin-Destination matrix was estimated for those two periods, which allowed to conclude that the traffic volume in the area of the ring road already constructed will suffer a reduction, while in the city center roads the changes in traffic flows will be insignificant., Modeling of the road network of the city of Guimarães.

Resumo Um dos principais problemas das redes viárias das cidades é o desequilíbrio existente entre a oferta e procura associado ao uso massivo do transporte motorizado que conduz a frequentes congestionamentos de tráfego em zonas sensíveis e eixos estruturantes destes territórios. Este fenómeno é uma das causas do aumento do nível de ruído e poluição e redução da segurança nos centros urbanos que afeta diretamente a qualidade de vida das populações. De forma a estudar o impacto de várias alterações na cidade de Guimarães é apresentado neste artigo o procedimento de modelação e afetação do tráfego à rede viária da cidade através da utilização do software PTV Visum. Neste âmbito estudou-se uma possível conclusão da Variante - principal via arterial da cidade, pela encosta do Monte da Penha, para a hora de ponto da manhã e da tarde. Para efetuar o seu estudo foi estimada a matriz Origem – Destino para as duas horas de ponta a partir de dados de contagem de tráfego, tendo-se concluído que o volume tráfego no troço da circular já construída sofreu uma redução do tráfego, mas sem que se verificassem grandes alterações nos fluxos das vias do centro da cidade, info:eu-repo/semantics/publishedVersion

Trabajo presentado en la International Conference Advances in grain legume breeding, cultivations and uses for a more competitive value-chain, celebrada en Novi Sad (Serbia) el 27 y 28 de septiembre de 2017., Consumers worldwide are increasingly concerned with food quality and environmental sustainability. Grass pea (Lathyrus sativusL.) is a robust grain legume with high nutritional value. This environmentally friendly legume may be an excellent response to consumers’ concerns. However, a reduced breeding investment has hampered its use in Europe. To increase grass pea consumption and cultivation, breeding objectives and consumer preferences should be aligned. However, breeding for improved end-user ́s quality is a complex task in legumes due to high trait interaction. Particular grass pea metabolites might act as health-promoting agents as well as antinutrients, influencing both taste and consumers’ acceptability, and interfering with plant resistance to different stresses. Under the scope of LEGATO EU project, we studied the genetic basis of several of these dual-action bioactive compounds as a first step to develop molecular tools (functional markers) for redirecting breeding towards more attractive grass pea varieties. For attaining this, seed metabolites contents (such as phenolic compounds or β-ODAP) of a worldwide collection of 116 grass pea accessions were analyzed by HPLC and HPLC-MS/MS (liquid chromatography tandem -mass spectrometry). A genome-wide association study using the phenotypic information from one to two years of field experiments, combined with the genotypic information from a DArTseq based-SNP screening is currently ongoing. Relevant sources of these bioactive compounds will be detected and marker-trait associations tested using a mixed linear model that accounts for population structure and familial relatedness. Results obtained from this analysis will be reported.

The main goal of this study was to identify a set of factors considered relevant by basketball experts in a young player's route to high performance. The impossibility of choosing one as the most preponderant factor comes from the complex interaction between the different areas that influence the long development path of athletes to sport expertise. Our sample consisted of 14 coaches (7 of men's level and 7 of youth level), 7 players and 7 club coordinators who were asked to give their view on the subject by means of an interview. One of the main conclusions was the decisive influence of environmental factors, especially the family and coaches' influence, both as promoters of the beginning of the activity and as the maintenance in it. Psychological factors - athlete's work ethic and surpassing capacity - were also referred as having a great role on this issue. Technical, tactical and physical factors (in this order of importance) come as an asset to the young athlete. Finally, we conclude that the training process should be defying and constantly adjusted to the athlete's needs, creating stimulus that allow the young player to develop strategies to read and understand of the game, as well as decision making processes. The context where the athlete is inserted, as well as the psychological aspects and knowledge of the game must be considered the most relevant factors. El objetivo principal de este estudio fue identificar un conjunto de factores considerados relevantes por los expertos de baloncesto en la ruta de un joven jugador de alto rendimiento. La imposibilidad de elegir uno como el factor más preponderante proviene de la compleja interacción entre las diferentes áreas que influyen en el camino de desarrollo a largo de los atletas a la experiencia deportiva. Nuestra muestra fue constituida por 14 entrenadores (7 del nivel de los hombres y el 7 de categoría juvenil), 7 jugadores y 7 coordinadores del club que proporcionaran su opinión sobre el tema por medio de una entrevista. Una de las principales conclusiones fue la decisiva influencia de los factores ambientales, especialmente la influencia de la familia y entrenadores, ambos como promotores de la inicio de la actividad y como el mantenimiento en el mismo. Los factores psicológicos - ética de trabajo del atleta y la capacidad de superación - también fueron referidos como teniendo un gran papel en este tema. Los factores técnicos, tácticos y físicos (en este orden de importancia) son considerados un activo para el joven atleta. Por último, llegamos a la conclusión de que el proceso de formación debe ser constantemente desafiante y ajustarse a las necesidades del atleta, debe proporcionar la creación de estímulos que permitan al joven jugador desarrollar estrategias para leer y entender del juego, así como los procesos de toma de decisiones. El contexto en el que se inserta el atleta, así como los aspectos psicológicos y conocimiento del juego se deben considerar los factores más relevantes. O principal objetivo deste estudo foi identificar um conjunto de fatores considerados relevantes por especialistas de basquetebol no percurso de um jovem jogador para o alto rendimento. A impossibilidade de escolher um único fator como o mais preponderante advém da complexa interação entre as diversas áreas que influenciam o caminho de desenvolvimento de longo dos atletas à experiência esportiva. A nossa amostra foi constituída por 14 treinadores (7 de nível dos homens e 7 do nível da juventude), 7 jogadores e 7 coordenadores do clube que foram convidados a dar a sua opinião sobre o tema por meio de uma entrevista. Uma das principais conclusões foi a influência decisiva de fatores ambientais, especialmente a influência da família e treinadores, ambos como promotores do início da atividade e quanto à manutenção na modalidade. Os fatores psicológicos - ética de trabalho do atleta e capacidade de superação - também foram referidos como tendo um grande papel nesta questão. Fatores técnicos, táticos e físicos (por esta ordem de importância) são considerados mais-valias para o jovem atleta. Finalmente, podemos concluir que o processo de formação deve ser desafiante e constantemente ajustado às necessidades do atleta, criando estímulos que permitam ao jovem jogador desenvolver estratégias de leitura e compreensão do jogo, bem como os processos de tomada de decisão. O contexto em que o atleta está inserido, bem como os aspetos psicológicos e conhecimento do jogo devem ser considerados os fatores mais relevantes.

This work aims to study a new energy harvesting device to be anchored on the ocean floor and convert any type of currents, tides or oscillation movement into electrical energy using linear electromagnetic generators. The final application is to supply energy to a set of moored monitoring sensors that collects data and allowing the system to be energetically autonomous. The proposed setup is a spherical buoy with no external moving parts, to be more biofouling proof. The maximum output power measured for a 4 Hz movement was 9.9 mW with only one linear electromagnetic generator.

In this paper, a survey of the mobile data traffic growth over the last decade is performed, showing historically how data consumption patterns have evolved. Based on the results from the survey and the most important factors for unprecedented traffic growth from last years, a set of user-centric services and scenarios are identified as the most prevalent by 2020. Based on service characteristics and subscribers' behaviour and consumption regarding traffic generation, four user segments are derived. All these factors allow introducing an impact model that characterises user segment's behaviour over post-4G cellular networks, namely, its consistency and stability towards traffic generation, data consumption and service usage, providing mobile network operators with relevant information to predict user segment dispersion, stability and risk. Real and estimated market data are used to test the impact model, and most relevant results are shown. Overall, the proposed impact model aims to bring together technological, sociological and also economical perspectives into a single analytical framework, meeting both mobile network operators and subscriber's expectations of high quality of service with continuous cost decrease. info:eu-repo/semantics/publishedVersion

Andropogon gayanus is an important grass due to its high biomass production, drought tolerance and favorable growth on low fertility acidic soils. Currently, there is little research on the impact of growth stage on the nutritional quality or the degree of CH4 production that may arise from this forage during ruminal fermentation. The objectives of this study were to determine the effects of regrowth stage of A. gayanus on its chemical composition, in vitro production of gas and CH4, as well as in vitro dry matter (DM) digestibility when grown under tropical Brazilian conditions and conserved as hay or as silage. The nutritional value of A. gayanus grass declined with increasing maturity; however digestible DM yield linearly increased. After 112 d of regrowth, A. gayanus produced higher quality silage (higher lactate and lower pH and butyrate content) and higher DM yield. However, the low levels of crude protein at this time would make protein supplementation a necessity for proper rumen fermentation. No differences in CH4 kinetic parameters were found with advancing maturity or preservation method (hay or silage).

Experiments were designed to determine if the juvenile forms of jundia (Rhamdia quelen) exhibit selectivity feeding on zooplanktonic organisms and the influence of intraspecific competition on the diet. The fish were maintained in 5000-L containers, and after seven days from birth, they were acclimated in experimental units with different densities and supplied with water containing plankton (natural), where they remained for 24 h in the environment with food. In the first seven days at densities of 5 and 10 fish.L–1, the fish selected the Rotifera more intensely, and at densities of 20 and 40 fish.L–1, the Cladocera were more selected. At 14 days of age, the Cladocera were the most selected for all densities of fish. At 21 days of age, the juvenile forms of jundia maintained a preference for Cladocera, and there was an increase in the capture of Copepoda at a density of 40 fish.L–1. At 28 days of age, the Cladocera were the most captured at densities of 5 to 20 fish.L–1, and the consumption of copepods increased at a density of 40 fish.L–1. The juvenile forms of Rhamdia quelen showed a high feeding preference for Cladocera at all the ages tested (7, 14, 21 and 28 days), but the density of fish per litre influenced the capture of the preferential food. This study showed that the juvenile forms of jundia had a more rapid response to the presence of food at densities of more than 10 fish.L–1, and that at higher densities the fish decreased interactions of territorial defense and formed schools, which allowed the foraging of zooplanktonic organisms, larger in size, more agile and of greater energy gain, such as the Cladocera and copepods.

As lipases (E.C. 3.1.1.3) são um grupo de enzimas capazes de catalisar a hidrólise da ligação éster de triacilgliceróis, gerando ácidos graxos livres e glicerol. As lipases microbianas são muito utilizadas nas aplicações industriais nas áreas de alimentos, síntese orgânica e farmacêutica. Neste trabalho, visando à produção de lipase a partir da levedura Candida rugosa foram utilizados meios de cultura alternativos compostos por melaço, milhocina e águas russas. As fermentações foram conduzidas em agitador rotatório a 30 °C e 170 rpm. Testaram-se quatro meios contendo diferentes combinações dos resíduos acima mencionados. O meio contendo melaço 10 g/L, milhocina 4 g/L e águas russas 1,0 %(v/v) foi o que propiciou a produção de enzima com maior atividade intracelular 269 ± 10 U/L frente ao substrato pNFL (p-nitrofenil laurato). Esses resultados demonstram que o referido meio alternativo contendo resíduos agroindustriais é adequado para a produção de lipase.

As lipases (E.C. 3.1.1.3) são uma classe de enzimas que catalisam a hidrólise dos triglicerídeos de ácidos gordos livres e glicerol. Essas enzimas encontram uma grande aplicação nas indústrias de alimentos, detergentes, cosméticos, síntese orgânica e farmacêutica. Neste trabalho, as leveduras Candida tropicalis e Meyerozyma caribbica isoladas do bagaço de caju foram testadas quanto à sua capacidade de produção de lipase. As fermentações foram conduzidas em agitador rotatório a 30 °C e 170 rpm. A medida da atividade foi feita através da hidrólise com o pNFL (p-nitrofenil laurato). Para a produção da enzima foi utilizado um meio de cultura contendo resíduos agroindustriais, nomeadamente melaço 10 g/L, milhocina 4 g/L, águas russas 1,0 % (v/v). A atividade do sobrenadante da C. tropicalis foi 233 ± 10 U/L e da M. caribbica foi 146 ± 7,30 U/L em 24 h de fermentação. Esses resultados mostram o potencial dessas estirpes para a produção da enzima lipase a partir de resíduos agroalimentares.

The need for more sustainable and environmentally safe agriculture has reinforced interest in legume cultivation in Europe. These species have the unique capacity for symbiotic nitrogen fixation, highlighting their importance in both natural and agricultural ecosystems. In addition, genotypes that are naturally resistant to pathogens are useful for reducing pesticide application. Grass pea (Lathyrus sativus) is a feed, food and fodder crop, with great adaptability to inauspicious environments, high protein content and resistance to serious diseases. It is one of the most promising sources of calories and protein for the drought-prone and marginal areas of Asia and Africa, being an alternative to marginal soils and for cropping systems diversification in Europe. As part of the European LEGATO and the Portuguese QUALATY projects, we focus on the search for resistance sources to weevils and fungal diseases on a collection of hundred grass pea genotypes from diverse origins, including Europe, Africa and Asia. Along with the phenotypic observations (resistance level) on field and controlled conditions, we used DArT-seq and E-SSRs to access the genetic diversity within and among grass pea accessions. This will allow identifying any relationship between genetic diversity and resistance level. The acquired data will reveal valuable diverse sources of resistance for the development of modern grass pea cultivars, improving the attractiveness of this underused but promising crop., Trabajo presentado en el Second International Legume Society Conference "Legumes for a sustainable world" (ILS2), celebrado en Tróia (Portugal) del 11 al 14 de octubre de 2016.

Trabajo presentado en el Second International Legume Society Conference "Legumes for a sustainable world" (ILS2), celebrado en Tróia (Portugal) del 11 al 14 de octubre de 2016., Today's consumers are increasingly concerned with food quality and sustainability. Grain legumes could play an important role in answering these concerns. Grass pea (Lathyrus sativus) is a promising source of calories for drought-prone areas while common bean (Phaseolus vulgaris) is the most important edible legume worldwide. Yet the nonalignment of breeding objectives and end-users preferences is hampering their use in Europe. Breeding for improved end-user ́s quality is a complex task due to trait interaction. Particular metabolites act as antinutrients as well as health-promoting agents, influencing both taste and consumers’ acceptability. Under the scope of LEGATO, BEGEQA and QUALATY projects, we studied the genetic basis of several of these dual action bioactive compounds (as phenolic compounds, phytic acid or -ODAP) as a primary step for devising innovative quality breeding approaches for common bean and grass pea. To reach these goals, 100 grasspea and 150 common bean accessions were repeatedly field trialed. Seed metabolites contents were analyzed using different analytical approaches and DNA screened using NGS-based SNP genoty ping. A genome-wide association study, joining bioactive compounds content phenotypes with genomic information, is ongoing using mixed linear models to account for population structure and familiar relatedness. Functional markers will be identified conferring consumer-driven quality traits, to redirect breeding towards more attractive varieties.

Medication resistant neurological and psychiatric disorders, RNPD, are devastating multicausal chronic diseases that cannot be adequately controlled using conventional pharmaco and/or psychotherapies, being epilepsy a well-known RNPD. Wireless biomedical device availability is growing at an impressive rate, and the systems' miniaturization, integration and complexity is also increasing, unveiling new therapies based on such new devices. This paper presents a new wireless implantable device as a solution for thermal neuromodulation of brain cells, which can be used to treat or study the brain's behavior when cooled down. The obtained results show that, despite these systems' potential to be power hungry, they may operate within acceptable electrical power values, while reaching the required neuromodulation temperatures., This work has been supported by FCT (Fundação para a Ciência e Tecnologia) in the scope of the project PTDC/EEITEL/5250/2014, project PTDC/CTM-NAN/5414/2014 and under grant SFRH/BD/100649/2014., info:eu-repo/semantics/publishedVersion

O objetivo deste experimento foi estudar a degradabilidade in situ e a cinética de degradação da fibra em detergente neutro (FDN) e fibra em detergente ácido (FDA) das silagens de quatro genótipos de sorgo, com presença e ausência de tanino nos grãos. Foi utilizado um delineamento experimental de blocos ao acaso, em esquema de parcelas subdivididas, sendo os animais os blocos, as silagens as parcelas e os tempos de incubação as subparcelas. As médias foram comparadas pelo teste SNK, a 5% de probabilidade. Após 96 horas de incubação, as degradabilidades da FDN e FDA variaram de 32,22 a 56,07% e de 26,40 a 54,40%, para as silagens do BR700 e CMSXS165, respectivamente. A presença de tanino nos grãos comprometeu a degradabilidade ruminal da FDN e FDA das silagens de sorgo.

Avaliou-se o padrão de fermentação de silagens do híbrido de sorgo forrageiro BR 601 com ou sem aditivos. Foram adotados os tratamentos: silagem sem aditivo (testemunha) e silagens adicionadas com 0,5% de uréia, 0,5% de carbonato de cálcio, 0,5% de uréia mais 0,5% de carbonato de cálcio e com inoculante bacteriano. Os materiais foram ensilados em silos de “PVC” e abertos com um, três, cinco, sete, 14, 28 e 56 dias de ensilagem. Determinaram-se as variações nos teores de matéria seca (MS), os teores de fibra em detergente neutro (FDN), hemicelulose, celulose, fibra em detergente ácido (FDA), lignina e a digestibilidade “in vitro” da MS (DIVMS). Adotou-se o delineamento inteiramente casualizado, em um esquema fatorial 5 x 7, sendo as médias comparadas pelo teste SNK a 5%. As silagens tratadas com a associação entre uréia e carbonato de cálcio apresentaram as maiores perdas de MS. Os aditivos não promoveram alterações nos teores de FDN, hemicelulose e celulose e na DIVMS. Ocorreu diferença entre a silagem testemunha e as silagens com aditivo, com a evolução do processo fermentativo, quanto aos teores de FDA e lignina.

Avaliaram-se quatro híbridos experimentais e duas cultivares comerciais de Sorghum bicolor cv bicolor x Sorghum bicolor cv sudanense quanto às características agronômicas: produções de matéria verde por hectare (MV/ha), matéria seca (MS/ha), altura das plantas, número de plantas/ha, taxa de rebrota e relação folha/haste. Os plantios ocorreram na transição do período seco para o período chuvoso. Os híbridos foram submetidos a três cortes sucessivos, realizados em duas épocas de plantio. Foi empregado um delineamento experimental de blocos ao acaso e a comparação de médias foi efetuada pelo teste de SNK, a 5% de probabilidade. Os híbridos estudados não diferiram para a maioria das características avaliadas, com exceção da população de plantas, em que o híbrido experimental ATF 54 x CMSXS 912, com 848 mil plantas/há, foi semelhante (P>0,05) aos híbridos testemunhas (comerciais) AG2501C, com 780 mil plantas/ha, e ao BRS800, com 749 mil plantas/ha, sendo superior (P

Avaliaram-se a composição química e indicadores do padrão de fermentação de silagens do híbrido de sorgo forrageiro BR 601 [Sorghum bicolor (L.) Moench], submetidos aos seguintes tratamentos: silagem sem aditivo (testemunha), silagem com 0,5% de uréia, silagem com 0,5% de carbonato de cálcio, silagem com 0,5% de uréia mais 0,5% de carbonato de cálcio e silagem com inoculante bacteriano. Foram utilizados silos experimentais de PVC, com 10 cm de diâmetro e 50 cm de comprimento, abertos com um, três, cinco, sete, 14, 28 e 56 dias de vedação. Logo após a abertura, foram determinados o pH e os teores de nitrogênio amoniacal, como porcentagem do nitrogênio total (N-NH3/NT), os teores de matéria seca (MS), proteína bruta (PB) e carboidratos solúveis (CHOs). O delineamento experimental foi inteiramente ao acaso, com duas repetições por tratamento. As médias foram comparadas pelo teste SNK, a 5% de probabilidade. Pouco efeito dos aditivos foi observado sobre o perfil de fermentação das silagens, de forma que o tratamento controle resultou em silagem de boa qualidade. O uso da uréia ou uréia com carbonato de cálcio resultou em aumento do pH e do nitrogênio amoniacal.

This paper presents a Maximum Power Point Tracking (MPPT) circuit in CMOS technology for integration into an energy harvesting solution, comprising a solid-state thin-film lithium battery fabricated in the back side of a plastic solar cell. The MPPT CMOS circuit is required in the energy transfer process from the solar cell to the battery. The MPPT circuit was designed in the 0.7 µm CMOS process from on semiconductor (former AMIS, Alcatel-Mietec). The pulse width modulation (PWM) gate control of the DC-DC step-up converter is obtained only with analog circuits, which are composed by rail-to-rail operational amplifiers, analog multipliers and a ring oscillator. The ripple correlation control algorithm is used in the implementation of the analog MPPT circuit. This is a dynamically rapid method (e.g., 5 ms step response was measured) where the inevitable ripple of the inductor current of the DC-DC converter is analyzed and used to adjust the set-point of the same DC-DC converter. The full energy harvesting is also described in this paper.

Organizations have become increasingly dependent on information systems to perform their business as usual activities. Moreover, organizations have registered an increase in the number of cyber-attacks, namely: industrial espionage, confidential information leakage, digital theft or pure damage to corporate image and reputation. In order to try to mitigate these issues, organizations like the National Institute of Standards and Technology (NIST) have made an effort to establish a cybersecurity protection guide. This paper presents a baseline for developing a generic and flexible model for manipulating key factors inside organizations: Processes, Human Resources and Technology, and extrapolate the percentage of compliance with the NIST cybersecurity framework, measure the current cybersecurity risk and allocate financial investments towards specific compliance objectives and reduce the overlapping of existing resources. info:eu-repo/semantics/submittedVersion

In this work, a multilayer physical vapour deposition (PVD) thin-film encapsulation was developed for lithium microbatteries, see Figure 1. Lithium microbatteries with a lithium cobalt oxide (LiCoO2) cathode, a lithium phosphorous oxynitride (LiPON) electrolyte and a metallic lithium anode are under development by our group. Metallic lithium film is still the most common anode on this type of batteries, however presents a huge challenge in terms of encapsulation (almost instantaneously oxidation in contact with atmosphere). Despite the oxidation, lithium is also a material that reacts very easily with other materials, so lithium phosphorous oxide (LiPO) was the first material to deposit on top of lithium. To prove concept and perform all the experiments, lithium films were deposited on top of a glass substrate, with previously patterned titanium contacts. After deposition of lithium, the multilayer of thin-films were deposited without open the vacuum chamber. The multilayer is composed of LiPO, LiPON and silicon nitride (Si3N4), each film 20 nm of thickness. Si3N4 is a common material used in microelectronics to encapsulate devices and allows mechanical and dielectric protection to the battery. Si3N4 cannot be deposited directly on top of LiPO films because reactions occurred. Because of this reaction, LiPON was used to interface between LiPO and Si3N4 films with success. After breaking the vacuum, epoxy was applied on top of the Si3N4 thin-film. Metallic lithium was deposited by thermal evaporation and the three thin-films of multilayer deposited by RF sputtering. This PVD multilayer exonerates the use of chemical vapour deposition (CVD) and glove-Box chambers, reducing significantly the fabrication cost. To evaluate oxidation state of lithium films, the lithium resistance was measured in a four probes setup, to avoid wires/contact resistances and resistivity calculated, considering physical dimensions. In the graph of Figure 2, is visible that the theoretical lithium resistivity of 0.1 Ω.µm was maintained more than 5 hours. This work allows that all the battery, including encapsulation to be fabricated only recurring to PVD techniques and without any glove box.

Trabajo presentado en la V Meeting Asociación Española de Leguminosas, AEL (Eucarpia International Symposium on Protein Crops), celebrada en Pontevedra del 4 al 7 de mayo de 2015., The need for more sustainable and environmentally safe agriculture has reinforced interest in legume cultivation in Europe. These species have the unique capacity for symbiotic nitrogen fixation, highlighting their importance in both natural and agricultural ecosystems. In addition, genotypes that are naturally resistant to pathogens are useful for reducing pesticide application. Chickling pea (Lathyrus cicera L.) is a feed and fodder crop, with great adaptability to harsh environments, being tolerant to drought and water logging. They are also resistant to several important legume pathogens such as rusts, powdery mildew, bacterial blight and crenate broomrape. In this way L. cicera can be a potential source of resistance genes to related species and also a good option for cropping systems in marginal lands (Vaz Patto and Rubiales, 2014). Latest outputs in L. cicera research, such as the development of novel molecular tools and mapping populations, allowed diverse new paths in Lathyrus exploration. RNA-seq analysis of L. cicera response to rust inoculation generated the first transcriptome of the species allowing the development of several different types of specific molecular markers (EST-SSRs and SNPs). These were subsequently applied on the development of the first L. cicera linkage map and identification of QTLs underlying resistance to rust and powdery mildew (Almeida et al., 2014). By applying this information to the available data from other related legume spe- cies we are able to perform comparative mapping between L. cicera and the well studied legumes species, such as Medicago truncatula, Pisum sativum or Glycine max . These developments open new doors on legume synteny studies on the identification of candidate resistance genes. Results will be discussed.
