Solid solutions ZnxCd1−xS were compared by coprecipitation and sonochemistry methods, where x = 0.2 . This rate is the one that presents the best photocatalytic activity and the best performance for the production of hydrogen from a water source, according to our previous results. The influence of the synthesis method on the morphology and its electronic properties of the CdS and Zn0.2Cd0.8S systems was investigated, as well as the effect of the incorporation of Zn in the crystal lattice and its effect on the production of hydrogen from the division of water. X-ray diffraction characterization confirmed the formation of a solid solution corresponding to a face-centered cubic crystalline phase with preferential growth of (111), (220), and (311) planes and hierarchical morphology according to SEM and TEM microscopy, formed by aggregated nanoparticles of ZnxCd1−xS compound. The crystallite size decreased with the Zn incorporation in the crystal lattice from 8.61 nm by a coprecipitation method to 4.37 nm when the synthesis was assisted with sonochemistry, and the crystallite sizes range from 7.92 nm to 3.80 nm for the case of CdS pure. Other characterization techniques were also used, such as photoluminescence (PL), Raman microscopy, and N2 adsorption and desorption. The PL results show tunability of band edge emission as a function of zinc concentration in the Zn0.2Cd0.8S nanoparticles. For the water splitting to hydrogen production, the separation of the charge carriers promoted by the incorporation of Zn in addition to the shallow trap emissions generated defects in the catalyst structure; such processes are important factors found which increased with the sonochemical method, as well as the potential matched positions.

The objective of this study was to evaluate the development of pitaya cuttings in different substrates under different frequencies of irrigation. The experiment was conducted from January to May 2017 in a greenhouse at Universidade Federal Rural da Amazônia, Capitao Poço, Pará, Brazil. A completely randomized 3 × 7 factorial design with four replicates was used. Pitaya plants were grown from cuttings in three types of substrates (S1: potting soil; S2: potting soil + cattle manure + wood shavings; and S3: washed sand) under seven irrigation frequencies (24, 48, 72, 96, 120, 144, and 168 h). There was interaction between treatments for root dry matter production, root length variables, the other variables showed no interaction between treatments. The greater development of new and vigorous tissues of the aerial part, the substrates with composition black earth and black earth + manure + sawdust are indicated, and the adoption of the irrigation frequency of 72 h or 96 h. The use of substrate based on black earth + manure + sawdust, allows savings in the rational use of water and energy with the application of the 96 h irrigation frequencies, maintaining satisfactory levels of development to the plant. The washed sand substrate can be used for propagation when this material is abundant, however, greater attention should be paid to the supply of water and nutrients to the plant.

Sorghum bicolor (L.) Moench ,nutrient accumulation ,water deficit ,Plant Science ,Agronomy and Crop Science ,Food Science - Abstract
The increase in water demand in regions with limited good-quality water resources makes it necessary to study the effect of low-quality water on plant metabolism. Therefore, the objective of this study was to evaluate the effect of water and salt stress on the levels of mineral elements and accumulation of toxic elements Na+ and Cl− in the leaves and their consequences on the production variables of the sorghum cultivar IPA SF-15. The design adopted was randomized blocks in a factorial scheme (4 × 4), with four salt concentrations (1.5; 3.0; 4.5, and 6.0 dS m−1) and four irrigation depths (51.3; 70.6; 90.0, and 118.4% of crop evapotranspiration ETc) in three repetitions. To obtain nutrient, sodium, and chlorine contents in the leaf, we collected the diagnosis leaf from six plants per plot. For production data, we performed two harvests at 76 and 95 days after planting (silage point and for sucrose extraction). We evaluated the dry mass, fresh mass yield, and total dry mass for the two cutting periods and applied the F-test at the 5% significance level. There was an effect of water stress but not saline, making it possible to use saline water for sorghum irrigation. As for the toxicity of ions, the plant showed tolerance behavior to Na+ and Cl− ions. The grain filling phase was more sensitive than the final phase of the crop cycle.

Agriculture in semiarid regions commonly face problems because of salt and availability of irrigation water. Considering this, studies on cultures resistant to salt and water stresses involving sweet sorghum are required. Therefore, the aim was to evaluate the growth and other mechanisms of tolerance to salinity and water deficit in BRS 506 sweet sorghum. The experimental design was conducted in Upanema-RN, Brazil, in randomized blocks, where the isolated and interactive effect of 3 salinity levels, expressed as the electrical conductivity of irrigation water (1.5, 3.8, and 6.0 dS m−1), and 3 irrigation depths (55, 83, and 110% of crop evapotranspiration) were evaluated. During the cycle, sorghum adapted to the salinity and deficit irrigation depth, since stem height reduced only −5.5% with increasing salinity and −11.95% with decreasing irrigation depth, and aerial dry mass was affected by interaction only at the end of the cycle. Proline, total amino acids, and total soluble sugars were not differenced by stresses. Additionally, around 68.71% of total Na+ was at roots at the end of the cycle. In summary, sorghum BRS 506 was more tolerant to salt than water stress and used Na+ compartmentalization in root cells as the main tolerance mechanism.

The article presents a reflection on decent work management technologies in the global productive chains. Based on economic sociology and anthropology authors, it discusses the general characteristics of the global productive chains, especially the concept of decent work as a management technology for the labor´s international regulation. The empirical focus of this research was a clothing manufacturing productive chain in the south of Santa Catarina. Interviews were carried out with social and economic actors that are part of this sector, in particular, unions and entrepreneurs. As a conclusion, it is important to highlight that decent work management technologies have the formal merit of inserting the decent work guidelines into the contracts between the suppliers and subcontractors. However, the research points out that the asymmetries in the financial negotiations which are typical of the productive chains continue to promote precarious and informal work in the sector.

This work aimed to analyze the spatial behavior of plant formations and land use in the Ecological Tension Area Amazon—Cerrado. To this end, the Araguaia river basin was selected, in its low course, because it constitutes a physical-natural limit between the two Biomms, with intense dynamics of use and land cover Thus, in addition to researching scientific references and socioeconomic data from secondary sources, a geographic database was elaborated, with georeferenced data, and spatial operations are carried out. Among them, a supervised classification of land use and coverage, with multi-temporal analysis between the years 1984, 2000 and 2018. Thus, an expansion of 4.2 ha of Forest (Amazon biome) was observed on the savanic phytophysiognomy (Cerrado). However, the suppression of forested areas reached values around 21,700 km2, with direct conversions to anthropic activities, mainly pasture, about 71%. The results of the mapping compared with the data of the agricultural census show that the landscape of the Araguaia river basin, in its low course, is dominated by areas of pasture managed. However, public policies and government investments have fomented the expansion of agriculture in the direct bank of the river Araguaia, from 2000 onwards, and that the landscape of the left bank is dominated by pasture managed. Finally, it was found that the implantation of protective areas contributed to the vegetational regeneration of both biomms.

- Abstract
The study presents the sequence stratigraphy of the carbonate platform focused in lower part of Shuaiba Formation, as well as the organization of the arrangement formed by the cyclical sedimentological evolution at high-resolution scale, through the facies analysis, diagenetical imprints and finally, significance of stable carbonate isotope results in the building up of carbonate platform in southeast Abu Dhabi. Interpreted stratigraphic surfaces from integration of depositional facies reviewed in all available cored data within studied area and stable carbon isotope results allowed that four small-scale regression-transgression depositional cycles can be discriminated which are stacked into a medium-scale sequence, that may record a 600 kyr Milankovitch signal. The small-scale sequences were correlated within the studied area using both conventional well logs and stable isotope records. Transgression hemicycles represent the increasing of accommodation space and can be identified in direct evidence, such as 25-40 ft. thickness of lithocodium/bacinella floatstones and skeletal peloidal packstones facies, association of facies interpreted within upper slope sub-environment. Likewise, in δ13C profiles, the rise/fall turnarounds of small-scale sequences are marked by negative δ13C peaks and associated with characteristics patterns: (1) proportion decrease of shallower sub-environments facies is interpreted as an rising relative sea-level and (2) decreasing δ13C trends interpreted to be related to decreasing nutrient supply. The medium/big pores of floatstones poorly connected in packstone matrix are expressed in the medium/high porosity with low permeabilities. In contrast, regressive hemicycles represent the reduction in accommodation space and can be characterized in direct evidence, such as the growing up of persistent 10-20 ft. thickness with thousands of meters of correlation of stromatoporoids and rudist facies, association of facies interpreted within shelf-margin complex sub-environment. In addition, the fall/rise turnarounds are marked by positive δ13C peaks, associated with the stromatoporoids/rudists mounds with characteristic patterns: (1) proportion increase of shallower sub-environments facies is interpreted as falling relative sea-level and increase in proximity and (2) increasing δ13C values interpreted to reflect increasing nutrient supply. Unusually very high permeability is attributed to the present of fractures and dissolution events that is enhanced where proportion of stromatoporoids facies are more pronounced. The described characterization resulted in the identification of genetic cycles that reproduce the sedimentological evolution, which are presented in small-scale sequences. In addition, the δ13C values enabled to understand the internal organization and the development of the carbonate building up in the Shuaiba shallow platform evolution. This study provides update and understanding on sedimentary facies, depositional pattern, and expands on previous published works, using new approach from semi-regional to local scales. Finally, results help to understand the laterally extensive water break-through thin intervals, which are directly related to the regressive hemicycles described previously.

Objetivou-se estudar o desempenho agronômico do pimentão cv. Ikeda, irrigado com diferentes qualidades de água, sob dois métodos de manejos de irrigação: reflectometria no domínio da frequência e tensiometria, sob ambiente protegido. O delineamento estatístico utilizado foi o inteiramente casualizado, em esquema de parcelas subdivididas, constituído de três qualidades de água nas parcelas, e dois manejos de irrigação nas subparcelas. Foram avaliadas a produtividade total; produtividade comercial; eficiência do uso da água; massa média dos frutos; comprimento; diâmetro; relação comprimento/diâmetro; teor de sólidos solúveis; acidez titulável e pH. Os resultados obtidos permitem concluir que a produtividade e qualidade físicas dos frutos de pimentão não foram afetadas pela qualidade da água de irrigação, enquanto a menor demanda hídrica quantificada pela tensiometria influenciou significativamente apenas nos pH dos frutos.

We investigate the heat transport properties of a three-level system coupled to three thermal baths, assuming a model based on superconducting circuit implementations. The system-bath coupling is mediated by resonators which serve as frequency filters for the different qutrit transitions. Taking into account the finite quality factors of the resonators, we find thermal rectification and circulation effects not expected in configurations with perfectly-filtered couplings. Heat leakage in off-resonant transitions can be exploited to make the system work as an ideal diode where heat flows in the same direction between two baths irrespective of the sign of the temperature difference, as well as a perfect heat circulator whose state is phase-reversible., Comment: 14 single-column pages + references, 9 figures

Brazil has a large prison population, which places it as the third country in the world with the most incarceration rate. In addition, the criminal caseload is increasing in Brazilian Judiciary, which is encouraging AI usage to advance in e-Justice. Within this context, the paper presents a case study with a dataset composed of 2,200 judgments from the Supreme Federal Court (STF) about pre-trial detention. These are cases in which a provisional prisoner requests for freedom through habeas corpus. We applied Machine Learning (ML) and Natural Language Processing (NLP) techniques to predict whether STF will release or not the provisional prisoner (text classification), and also to find a reliable association between the judgment outcome and the prisoners’ crime and/or the judge responsible for the case (association rules). We obtained satisfactory results in both tasks. Classification results show that, among the models used, Convolutional Neural Network (CNN) is the best, with 95% accuracy and 0.91 F1-Score. Association results indicate that, among the rules generated, there is a high probability of drug law crimes leading to a dismissed habeas corpus (which means the maintenance of pre-trial detention). We concluded that STF has not interfered in first degree decisions about pre-trial detention and that is necessary to discuss the drug criminalization in Brazil. The main contribution of the paper is to provide models that can support judges and pre-trial detainees.

Earthquakes and landslides are common in the Philippines due to the country’s geography being situated along the Pacific Ring of Fire. In such events, structural collapse could occur and potentially trap humans inside. Rescue efforts either blindly search for the survivors or use expensive equipment to aid their search. Such equipment cannot be distributed to every local government unit. In this paper, we propose a low-cost light-weight vital sign detection system using radar technology. We have shown that a software-defined radio operating at the S-band can be used to detect human vital signs over a concrete wall. Due to its light weight, it can be mounted on a drone to improve the time it takes to rescue survivors.

General Medicine - Abstract
As tecnologias e artefatos tecnológicos, especialmente os digitais, estão presentes no espaço escolar e no cotidiano de muitos jovens em idade escolar. A democratização do acesso à informação e à alfabetização tecnocientífica na contemporaneidade tem importante relação com o acesso à estes artefatos e tecnologias. Se o espaço e o currículo escolar não são neutros e são alvo de disputas de projetos de ser humano e de sociedade, qual o lugar e o papel da tecnologia no ensino escolar? Sendo os artefatos e a tecnologia construções de uma realidade histórica e política (que também ajudam a construir), seria possível um projeto de base emancipadora e democrática para a tecnologia na escola? Nesse sentido, esse estudo teve como objetivo levantar o debate entre tecnologias e educação tendo vista um horizonte democrático e emancipador. Em uma abordagem crítica, buscou-se: (1) discutir as possibilidades de democracia e sua relação com a educação; (2) as relações entre educação e tecnologias; e (3) as relações entre as tecnologias e uma formação para a democracia. Observa-se que a inserção das tecnologias na educação pode fornecer instrumentos para a formação de uma sociedade democrática, sobretudo (mas não somente) pelo acesso à informação e aos recursos tecnocientíficos que pode possibilitar o desenvolvimento de sujeitos ativos e conscientes. Mas este acesso não está disponível para todos. A tecnologia, por sua vez, incorpora valores dos grupos sociais capazes de traduzir seus valores na técnica e nos artefatos. É preciso considerar também a agência destes artefatos e seus impactos sobre as pessoas e que sua mera inserção nos espaços educativos não necessariamente traduz uma perspectiva emancipadora. Desta forma, um olhar crítico para a relação entre tecnologia e educação passa pela problematização dos artefatos tecnocientíficos, sua situcionalização histórico-cultural e uma análise dos atores envolvidos e beneficiados por seu desenho.

General Medicine - Abstract
Este trabalho tem por objetivo discutir a inovação e algumas de suas principais representações e significações desde os primeiros usos da palavra na Grécia Antiga até o século XX. Busca-se, dentro dos limites destas breves páginas, trilhar os caminhos que levaram uma expressão de conotação política e que pouco ou nada tinha que ver com artefatos e tecnologia, para as significações vinculadas ao progresso, à economia, ao mercado e, mais especialmente, ao campo da ciência e da tecnologia. Para tanto, busca-se contextualizar as representações e narrativas acerca da inovação e os valores ético-políticos e sociais a eles associados por meio de uma abordagem crítica de reconstrução normativa imanente, identificando suas determinações sociais, políticas e econômicas. O que se observa é que as representações acerca da inovação não foram lineares, e em várias épocas assumiram sentidos próximos, ambivalentes e mesmo opostos, dependendo dos objetivos dos escritores e do contexto em que estavam inseridos. Os ideais normativos tiveram conotações diversas e polissêmicas, variando ao longo do tempo. Nem sempre inovação esteve associada à criatividade, artefatos e processos tecnológicos, nem tampouco vinculada à economia e ao mercado, o que aconteceu somente ao longo do século XX.

PURPOSE The LUME-Lung 1 study has brought consistent evidence of the effective use of nintedanib in lung adenocarcinoma as a second line of treatment; however, differences among ethnicities have been found in some studies. METHODS This was a retrospective review among 21 medical centers of 150 patients with a confirmed diagnosis of lung adenocarcinoma, included in a compassionate use program of nintedanib from March 2014 to September 2015. The current study aimed to analyze the effectiveness of nintedanib in combination with docetaxel in the Mexican population, using progression-free survival rate and the best objective response to treatment by RECIST 1.1 as a surrogate of effectiveness. In addition, we examined the toxicity profile of our study population as a secondary end point. RESULTS After exclusion criteria, only 99 patients met the criteria for enrollment in the current study. From the total study population, 53 patients (53.5%) were male and 46 (46.5%) were female, with an average age of 60 years and stage IV as the most prevalent clinical stage at the beginning of the compassionate use program. A total of 48 patients (48.5%) had partial response; 26 (26.3%), stable disease; 4 (4%), complete response; and 16 (16.2%), progression; and 5 (5%) were nonevaluable. We found a median progression-free survival of 5 months (95% CI, 4.3 to 5.7 months). The most common grade 3 or 4 adverse reactions were fatigue (14%) and diarrhea (13%). CONCLUSION Nintedanib, as part of a chemotherapy regimen, is an effective option with an acceptable toxicity profile for advanced lung adenocarcinoma after first-line treatment progression.

Purpose: The present study aims to describe the differences in the prevalence of EGFR mutation of lung adenocarcinoma between private and public healthcare institutions. Methods: This was a descriptive, observational, retrospective, multicenter study with confirmed diagnosis of non-small cell lung cancer, adenocarcinoma subtype, distributed between two private practice centers and one public healthcare institution. After a pathology review to determine whether there was enough tumor tissue to make a molecular biology study, mutations were determined using real-time PCR for EGFR tyrosine-kinase domain gene. Results: After exclusions a total of 328 patients results for the final analysis. Two hundred thirty-five patients (71.64%) attended a public healthcare institution and ninety-three patients (28.35%) to a private healthcare institution (Table 1). From the public healthcare institution, 113 (34.45%) patients had a positive EGFR mutation, while only 27 patients (8.23%) from the private healthcare institution were positive for an EGFR mutation. When comparing the total number of patients in the study, this difference was statistically significant when comparing public versus private hospitals (p=0.002). Conclusion: We found that there is a statistically significant difference between the frequency of EGFR mutations between populations attending public and private healthcare institutions, probably related to ethnic differences between populations. Despite what has been reported in the present study, these conclusions cannot be generalized and further investigation is needed.

O experimento foi conduzido na área experimental do DTCS-UNEB, Juazeiro, BA, no período de junho a setembro de 2015. Sob uma estrutura coberta com tela de sombreamento foi introduzida a cultura do tomate, instalado um tanque classe A (TCA) e uma estação meteorológica automática. A ETo da cobertura foi determinada a partir dos dados de evaporação do TCA instalado nesse ambiente e Kp = 1; e correlacionada com a ETo externa calculada por diferentes métodos de estimativas. A ETo da cobertura correspondeu a 77,8; 75,0 e 82,4% da ETo obtida pelos métodos de Penman-Monteith, TCA e Jensen e Haise, respectivamente; e 105 e 131,3% da ETo obtida pelos métodos de Hargreaves e Samani e Makkink, respectivamente. A evapotranspiração de referência em ambiente protegido pode ser estimada, com correlação elevada, a partir de dados externos, através do método do tanque classe A, com o Kp calculado para as condições climáticas locais.

R.REFERENCE EVAPOTRANSPIRATION ESTIMATE FOR A PROTECTED ENVIRONMENT 2 ABSTRACT Considering how important is the knowledge on the reference evapotranspiration (ETo) to estimate the different evapotranspiration demands, this study aims to evaluate the ETo coefficient in a protected environment, comparing it with estimates obtained from the open field conditions. The experiment was conducted in the test area of DTCS-UNEB, Juazeiro, BA, from June to September, 2015. Under a structure covered with a shading screen was introduced the tomato culture, a Class A pan (TCA) and an automatic weather station. The covered area’s ETo was determined using the evaporation data from the TCA installed in this environment and the coefficient Kp = 1; and correlated with the external ETo calculated by different estimation methods. The covered area’s ETo corresponded to 77.8; 75.0 and 82.4% of the ETo obtained by the Penman-Monteith, TCA and Jensen and Haise methods, respectively; and 105 and 131.3% of the ETo obtained by the methods of Hargreaves and Samani and Makkink, respectively. The reference evapotranspiration in a protected environment can be estimated, with high correlation, from external data, using the class A pan method, with a calculated Kp for the local weather conditions. Keywords: crop evapotranspiration, class A pan, ETo estimation methods

Background: Overexpression of estrogen receptors in malignant pleural mesothelioma has shown an independent relation with a better prognosis of survival, and the use of selective estrogen receptor beta (ERβ) agonists increases the susceptibility to antitumor treatment. Methods: This was a retrospective single center study that analyzed the response of malignant pleural mesothelioma with an expression of ERβ to first-line chemotherapy. The study included patients with pleural mesothelioma pathologically confirmed between 2013 and 2016 at the National Institute for Respiratory Disease (INER), who underwent an immunohistochemistry assay for ERβ (mouse monoclonal antibody PPG5/10). The primary endpoint was the response to chemotherapy based on RECIST 1.1 according to the ERβ expression; secondary outcomes were the overall survival (OS) and progression-free survival (PFS). Results: We included 22 patients, regarding the expression of ERβ, 17 (77.2%) patients had high or moderate degree, while 5 (22.7%) had low degree or null expression. The response to treatment as by RECIST 1.1, 12 (54.5%) had partial response, 5 (22.7%) had stable disease, and 3 (13.6%) had progression. None of the patients had a complete response. Of those who had a partial response, 9 (75%) had a high or moderate degree of ERβ expression in tumor cells, and 3 (25%) had a low or null degree of expression. Conclusions: High and moderate expression of ERβ group with advanced clinical stage malignant pleural mesothelioma was associated with a tendency of higher OS and better response to chemotherapy treatment resulting in longer PFS although statistical significance was not achieved.

Introduction: Osteoarthritis is a growingly common joint disorder affecting older adults. It is characterized by chronic low-grade inflammation, a phenomenon by itself considered a cardiovascular risk factor. However, data on its potential impact on cardiovascular disease (CVD) is scarce. Assessing hand osteoarthritis (HOA) might be advantageous when studying CVD as this particular location might be less affected by traditional cardiovascular risk factors such as overweight and physical activity. Hypothesis: HOA is associated with subclinical CVD. Methods: We cross-sectionally assessed the relationship between HOA and CVD in 1,803 women from the Mexican Teachers’ Cohort, excluding those with history of myocardial infarction, cerebrovascular disease, and rheumatoid arthritis. From 2012 to 2016, a subsample of the MTC participants from Mexico City and the states of Nuevo LeÓn, Chiapas, and YucatÅn were invited for clinical examinations in which standardized neurologists measured their carotid intima-media thickness (IMT) with ultrasound and a standardized HOA questionnaire was applied. HOA was defined as having ≥45 years, hand joint pain, and morning stiffness that lasts no longer than 30 minutes. Subclinical CVD was assessed through log-transformed IMT, and carotid atherosclerosis (CAS) was defined as mean right or left carotid IMT ≥0.8 mm or the presence of atherosclerotic plaque. Multivariable linear and logistic regression analyses were used to evaluate the association between HOA and IMT and CAS adjusting for age, state, smoking, alcohol consumption, diabetes, hypertension and body mass index. Results: Among participants with a mean age of 51 years (±4), 18.4% met the criteria for HOA, and the prevalence of CAS was 23.1%. After multivariable adjustment, women diagnosed with HOA had 1.6% (95%CI 0.2, 3.1) higher mean IMT than those without the joint disease. Similarly, women with HOA had 35% (95%CI 1.01, 1.81) higher odds of CAS. Sensitivity analyses using a less stringent definition of OA (pain regardless of stiffness), as well as incapacitating pain, did not have a significant association with CAS. Conclusion: Among middle-aged women, HOA was associated with subclinical CVD. This relation might be due to low-grade chronic inflammation, but further research is needed to clarify the underlying mechanisms, the role of screening for HAO as part of cardiovascular risk profiling, and the value of potential interventions such as anti-inflammatory drugs.

General Medicine - Abstract
As telas de sombreamento apresentam-se com perspectivas de possibilitarem altos níveis de produtividade para algumas culturas sensíveis ao excesso de radiação; e representam uma alternativa as condições climáticas que impossibilitam o cultivo a céu aberto. Entretanto, promovem alterações microclimáticas que invariavelmente afetam os componentes do balanço de energia, como os fluxos de calor sensível e latente, implicando em alterações no crescimento, desenvolvimento e produção das culturas. Objetivou-se no presente trabalho, avaliar os efeitos da tela de sombreamento sobre o microclima no cultivo de tomate cereja e estimar equações que correlacionem elementos climáticos dentro e fora do ambiente protegido. Uma estrutura com 12 x 18 m e pé direito 4 m foi construída e coberta com tela de sombreamento Chromatinet cor cinza; sob essa estrutura e a campo aberto foram cultivados em vasos com capacidade para oito litros, dois híbridos de tomate cereja, adotando-se delineamento experimental, blocos casualizados, esquema fatorial 4x2 (taxas de reposição da ETc versus híbridos de tomate), quatro repetições. Em cada ambiente os microclimas foram monitorados por meio de sensores meteorológicos acoplados a sistemas automáticos de coleta de dados. A tela de sombreamento promoveu atenuação de aproximadamente 39% da radiação verificada a campo aberto. O uso da tela de sombreamento promoveu alterações microclimáticas com aumento de temperatura, redução da umidade do ar, radiação global e velocidade do vento. As equações de estimativas revelaram alta correlação entre as variáveis meteorológicas dentro e fora do ambiente protegido.

- Abstract
Este trabalho apresenta os resultados de uma oficina de intervenção metodológica executada com alunos do 6º ano do ensino fundamental, tendo como tema “A Educação Ambiental em áreas e Ecossistemas de Manguezal”. A presente pesquisa foi desenvolvida com o objetivo de construir e fomentar os conhecimentos relacionados à Educação Ambiental dos alunos da educação básica, sobre o grau de poluição do ecossistema de manguezal, estimulando-os a serem os multiplicadores da importância da proteção desse ecossistema. O trabalho se desenvolveu a partir da realização de uma oficina educativa na escola. Esta oficina aplicou o trabalho de campo como método de ensino e aprendizagem, incluindo também, aulas multimídias em sala de aula com exposição de fotos e vídeos. No entanto, o principal foco foi na execução do trabalho de campo, nas áreas de manguezais existentes na cidade de São Caetano de Odivelas, no Pará. E, no intuito de verificar a eficácia no processo de ensino-aprendizagem, foram aplicados questionários aos alunos, antes e após a realização da oficina, sendo solicitado, também, que os mesmos representassem as áreas de manguezal através de desenhos. Assim, foi constatado que 84% dos alunos, mesmo residindo em áreas com manguezal, desconheciam as características do ecossistema antes da oficina de intervenção; e após a oficina pode-se constatar um aproveitamento de 96%. Portanto, infere-se que esta metodologia torna o processo de ensino-aprendizagem mais proveitoso e eficaz, possibilitando, inclusive, a construção de conhecimento em conjunto com o aluno que impulsionem a preservação e conservação do ecossistema de manguezal.

A la escuela del presente siglo le asiste una enorme responsabilidad de acompañar y orientar competencias, saberes y habilidades que le permitan al estudiante responder a los avances y retos del desarrollo científico, tecnológico y de la vida en sus diversas facetas. Además, la formación en específico propiciada por los docentes del área de las ciencias naturales, con respecto a la apropiación de los conocimientos y a la búsqueda de nuevas verdades, requiere del fortalecimiento ingente de programas, enfoques y estrategias; que posibiliten la consolidación de una cultura científica en el niño(a) o joven, articulada a formas comprensivas y explicativas de admitirlo. En ese sentido, es importante destacar a Macedo (2009, p. 9), quien en su discurso ante UNESCO sostiene que: “la educación de base debería asegurar la adquisición de una cultura científica, ampliada y reforzada en la educación secundaria en el marco de una educación para todos, que contribuya a la formación de los alumnos –futuros ciudadanos y ciudadanas– para que sepan desenvolverse en un mundo marcado por los avances científicos y tecnológicos. y para que sean capaces de adoptar actitudes responsables, tomar decisiones fundamentadas y resolver problemas cotidianos”.

The efficiency of a functionalized Disordered Mesoporous Silica-1 (DMS-1) to remove mercury ions disperse in water was evaluated. This material was functionalized using 3-mercaptopropyltrimethoxisilan as the source of thiol groups using the post-synthesis method. The aforementioned sorbent system was characterized using N 2 adsorption-desorption isotherms, Fourier Transform Infrared spectrometry (FTIR), Thermogravimetric Analysis (TGA), Small Angle X-Ray Diffraction (SAXD) and Scanning Electron Microscopy (SEM). These characterizations showed that the functionalized meshes possess the suitable microstructure and textural properties to be use as an adsorbent to remove mercury ions from water. Adsorption experiments showed a significant reduction of mercury ions of up to 99% of the total concentration contained in a synthetic solution (132 mg/l).

The white-browed guan (Cracidae: Penelope jacucaca) is an endemic bird species to the Caatinga, the largest centre of dry forest in South America. This taxon was considered Vulnerable by the International Union for Conservation of Nature (IUCN) due to continued habitat loss within its distribution and intense hunting pressure that contributed to population declines. However, information on population aspects and habitat use by P. jacucaca, which is fundamental for monitoring its conservation status, is not available. We studied habitat use (analysed in a Generalized Linear Model) and population density (estimated by distance sampling) in a specific area in Northeast Brazil. Using species distribution modelling (SDM), forest cover loss data (performed in the MaxEnt program) and quantitative information about hunting, more rigorous estimates of the distribution limits, available habitat, and population declines of P. jacucaca were generated. Based on the IUCN criteria, we applied analysed data to reassess the conservation status of the white-browed guan. Local density was estimated at 13.1 individuals/km2 and the estimated number of individuals removed per year due to hunting was 121.7 in the forest cover area (110.46 km2) of the Serra de Santa Catarina. Consequently, the annual removal rate of hunted individuals in the study area corresponds to approximately 11% of the population. The habitat use analysis pointed to a strong positive association with seasonally dry deciduous forest (SDDF) vegetation and with arboreal vegetation. The SDM indicated a potential distribution (climatically favourable) area of 675,823 km2, and forest cover and loss calculations indicated a total of 81,307 km2 of available suitable habitat in 2013. Therefore, comparing these results to the IUCN criteria, we recommend that P. jacucaca remain in the Vulnerable category.

Melanoma is the most malignant type of skin cancer due to its ability to metastasize. Since early detection is the best way to prevent it, many detection techniques have been developed, such as the ABCD rule, the Menzies method and the 7-point checklist. Digital image processing is nowadays a powerful and useful tool for the analysis of biomedical images, resulting in great help in the diagnosis of many diseases. Consequently, by using this tool it is possible to develop software capable of automatically recognizing different patterns of pigmented skin lesions. In this paper we propose an algorithm based on the morphological analysis of an image of a pigmented skin lesion in order to characterize and quantify its malignity according to the ABCD rule developed by Stolz in 1994. The proposed method includes image enhancement techniques, the segmentation of the injured area together with morphological algorithms to obtain the ABCD characteristics, and the calculation of the Total Dermoscopy Score (TDS), which will let us classify the lesion as benign, suspicious or malign. The results obtained show that the proposed algorithm is reliable and could help the medical professional in the diagnosis of melanoma.

Introduction Know the additional risks associated with hypertensive disorders in pregnancy, such as the use of licit and illicit substances, may contribute to the adoption of strategies that minimize adverse outcomes. Objective Estabilish the prevelence of the use of harmful substances such as alcohol, tobacco and ilicit drugs in pregnant women in relation to healthy pregnant women. Methodology A transversal study has been conducted in the prenatal and maternity of the Hospital Guilherme Alvaro from April to June 2016. 61 patients were selected, 34 from the study group and 27 from de control group. Among the patients in the study group, are included pregnant or postpartum women with hypertensive disorders, according NHBPEP 2000. In the control group, are included only pregnant or postpartum women without previous comorbidity, which gave birth to one healthy live newborn, vaginal delivery. It was applied two questionnaires, ASSIST, screening test of involvement with alcohol, tobacco and illicit substances, developed by WHO, useful for health professionals to identify the use and dependence on psychoactive substances, evaluated through a score, the answer ranges from 0 to 4 points, and the sum can range from 0 to 20, it is considered casual use 0 to 3, 4 suggestive of abuse 4–15 and suggestive of addiction 16–20. And another that evaluates epidemiological woman information, current and obstetric pregnancy as well as age, color, living city, number of consultations prenatal, site of consultations, among others. The data were passed to the Excel program and analyzed quantitatively, to compare Study and Control groups on the ASSIST score related to each psychoactive drug, we used the Student’s T Test for unrelated samples. It was considered significant samples where p Results The obtained results, shown below, do not allow to say that the groups differ, although the sample size and the low frequency of drug use in the groups studied compromise the accuracy of information. In percentage, 80.32% of all pregnant women have proved any drugs. Among the groups, the Study 70.83% have used drugs and in the control group 81.48% have used drugs. Psychoactive drugs most used by pregnant women are: alcohol 77,0% and tobacco 42,6%. In the correlation between the use of each type of drug with additional information about pregnancy and previous pregnancies – The use of tobacco, the less prenatal consultations, higher the score, in the Study group – The use of marijuana, the number of children who died (fetal or neonatal previous) was higher in the Study group – The use of cocaine, the number of children who died (fetal or neonatal previous) was higher in the Study group – The use of sedatives, the number of prenatal consultations, the highest score in the Study group SUBSTANCE Study % Control % Total % P Tobacco Alcohol Marijuana Cocaine Amphetamine Inalants Sedatives Hallucinogens Opiates.

Although we saw that the Hypertensive group made greater use of cocaine, amphetamine and opioids than those of the Control group. The other comparisons were not significant and the larger sample can clear the results.

Teoría de los quanta - Abstract
El tema de la presente tesis doctoral es: Transporte a través de sistemas mesoscópicos. Los sistemas mesoscópicos son materiales de un número de partículas pequeño, con un tamaño máximo del orden del micrómetro. Sus propiedades colectivas están regidas por la mecánica cuántica. En estos materiales, se estudia la dinámica de transporte, interacciones y coherencia de sistemas de una y unas pocas partículas. Los entornos considerados para el desarrollo de esta tesis son las estructuras de puntos cuánticos, donde partículas con un espín definido están confinadas en niveles de energía discretos. Los puntos cuánticos están acoplados por uniones túnel, que superponen las funciones de onda de los niveles de energía superiores. Las partículas en estos estados están deslocalizadas coherentemente por toda la estructura, que se comporta como una molécula artificial. Una fuerte interacción entre partículas está presente en estos sistemas debido a la proximidad entre ellas. Estos sistemas se controlan externamente cambiando voltajes de puerta acoplados capacitivamente a los puntos cuánticos. Por lo tanto, la energía, entropía y la dinámica coherente del sistema cambia de manera controlada. La mayor parte de esta tesis está basada en puntos cuánticos triples, los cuales constituyen un dispositivo perfecto para investigar interferencias entre distintos niveles. Tienen la ventaja de una separación espacial de los estados que permite manipularlos individualmente, y por otro lado el acoplo entre ellos también es controlado externamente. Al estudiar transporte de partículas, el sistema de puntos cuánticos se acopla débilmente a reservorios, con los cuales intercambia carga y energía. En el capítulo 7 se demuestran las interacciones entre distintos caminos entre los reservoiros usando un punto cuántico triple acoplado a tres reservorios. Las interacciones de Coulomb entre los electrones y las correlaciones entre los distintos caminos llevan a un bloqueo de la corriente en uno de los canales cuando el otro tiene una alta conductancia...
