Background: Obesity, a growing epidemic, is a preventable risk factor for cardiometabolic diseases. Obesity and cardiometabolic diseases affect Hispanics and African Americans more than non-Hispanic Caucasians. This study examined the relationship among race/ethnicity, obesity diagnostic measures (body mass index, waist circumference, subscapular and triceps skinfold thickness), and cardiometabolic risk factors (hyperglycemia, high, non-high-density lipoprotein cholesterol, low, high-density lipoprotein cholesterol, and hypertension) for adults across the United States. Methods: Using data from two-cycles of the National Health and Examination Survey (NHANES) 2007-2010, and accounting for the complex sample design, logistic regression models were conducted comparing obesity indicators in Mexican Americans, other Hispanics, and Black non-Hispanics, with White non-Hispanics and their associations with the presence of cardiometabolic diseases. Results: Differences by race/ethnicity were found for subscapular skinfold thickness and hyperglycemia. Waist circumference and subscapular skinfold were positively associated with the presence of hyperglycemia; dyslipidemia, and hypertension across race/ ethnicity, adjusting for age, gender, smoking, physical activity, education, income to poverty index, and health insurance. Race/ ethnicity did not influence the association of any obesity indicators with the tested cardiometabolic diseases. All obesity measures except triceps skinfold were associated with hyperglycemia. Conclusions: We suggest that subscapular skinfold thickness be considered as an inexpensive non-intrusive screening tool for cardiometabolic risk factors in an adult US population

Triamcinolone is a relevant anti-inflammatory costicosteroid drug, used mainly by injectable suspensions due its poor water solubility. The association of triamcinolone with cyclodextrins and co-solvents (triethanolamine TEA and N-methylpirrolidone NMP) was held to solubilize the drug and explain the involved interactions. Phase-solubility diagrams showed that triamcinolone was solubilized forming incredible stable complexes with cyclodextrins, in which bests results were observed applying randomyl-methylated-beta-cyclodextrin (RMβCD) (161 fold on increased solubility). The co-solvents TEA and NMP also enhanced drug solubility 1.4 and 6.7 fold, respectively. The association of both co-solvents with CDs seems decreased complexation stability, but enables higher amount of uncomplexed drug. Experimental magnetic resonance 2D-ROESY and theoretical molecular modeling studies demonstrated TRI-CDs interactions and elucidated the structure of formed complex, which occurred due to the inclusion of ring A of TRI on CDs cavity. Physicochemical aspects of solid binary and ternary complexes prepared by spray drying were assessed by using FTIR, X-ray diffraction and SEM photographs. Dissolution studies showed that binary and ternary associations presented higher dissolution efficacy in detrimental to pure drug system. In addition, the ternary complex containing TEA and RMβCD allowed drug dissolution faster than binary complex with RMβCD. Therefore, given the higher solubility and drug dissolution rate, binary and ternary complexes are new raw materials with great potential for pharmaceuticals containing triamcinolone.

The frailty syndrome is a geriatric medical condition of vulnerability resulting in the decline of physiological reserves, characterized by high-risk consequences as falls, disability, hospitalization, institutionalization and death. Although the presence of comorbidities is not always accompanied by fragility, this presence could also indicate an increased risk of adverse health events, taking the elderly to a greater likelihood of becoming brittle due to the physical limitations that may occur with emergence of diseases, which are strongly predictive of Fragility Syndrome. This study aimed to assess the prevalence of frailty syndrome in the elderly and associated factors. The specific objectives were to identify the prevalence of frailty syndrome in the elderly and their associations with demographic, economic, health, functional and psychological; identify the reasons for the prevalence of frailty syndrome with the demographic profile, health problems, use of legal drugs and problems with sleep of older people. The study was cross-sectional and composed of 385 elderly aged 65 or more. Multivariate Poisson regression models were used to check conditions associated with fragility and determine the prevalence ratio (α = 0.05). The prevalence of fragility was 8.7% and pre-fragility of 50.4%. Fragile and pre-frail elderly presented, bigger and increasing prevalence ratio for marital status, difficulty in performing instrumental activities of daily living, old age, involuntary loss of stool, depression and negative affect. Elderly people who do not work have a higher prevalence of fragility, as well as those who reported having had a stroke / stroke / ischemia, those who suffered falls in the last 12 months and those with sleep problems. It is considered that the results, together with other available in the literature, can contribute to the understanding of the fragility epidemiology and also in the implementation of specific programs aimed at reducing the prevalence of frailty, optimizing the quality of life. It is suggested that future programs have special attention to the profiles of elderly people who have not yet developed fragility, i.e., pre-fragile. This could prevent the elderly from becoming frail.

Polygonal tundra, thermokarst basins and pingos are common and characteristic periglacial features of arctic lowlands underlain by permafrost in Northeast Siberia. Modern polygonal mires are in the focus of biogeochemical, biological, pedological, and cryolithological research with special attention to their carbon stocks and greenhouse-gas fluxes, their biodiversity and their dynamics and functioning under past, present and future climate scenarios. Within the frame of the joint German-Russian DFG-RFBR project Polygons in tundra wetlands: state and dynamics under climate variability in Polar Regions (POLYGON) field studies of recent and of late Quaternary environmental dynamics were carried out in the Indigirka lowland and in the Kolyma River Delta in summer 2012 and summer 2013. Using a multidisciplinary approach, several types of polygons and thermokarst lakes were studied in different landscapes units in the Kolyma Delta in 2012 around the small fishing settlement Pokhodsk. The floral and faunal associations of polygonal tundra were described during the fieldwork. Ecological, hydrological, meteorological, limnological, pedological and cryological features were studied in order to evaluate modern and past environmental conditions and their essential controlling parameters. The ecological monitoring and collection program of polygonal ponds were undertaken as in 2011 in the Indigirka lowland by a former POLYGON expedition (Schirrmeister et al. [eds.] 2012). Exposures, pits and drill cores in the Kolyma Delta were studied to understand the cryolithological structures of frozen ground and to collect samples for detailed paleoenvironmental research of the late Quaternary past. Dendrochronological and ecological studies were carried out in the tree line zone south of the Kolyma Delta. Based on previous work in the Indigirka lowland in 2011 (Schirrmeister et al. [eds.] 2012), the environmental monitoring around the Kytalyk research station was continued until the end of August 2012. In addition, a classical exposure of the late Pleistocene permafrost at the Achchaygy Allaikha River near Chokurdakh was studied. The ecological studies near Pokhodsk were continued in 2013 (chapter 13). Other fieldwork took place at the Pokhodsk-Yedoma-Island in the northwestern part of the Kolyma Delta.

Fifty short sediment cores collected with a multiple corer and five box cores from the central Arctic Ocean were analysed to study the ecology and distribution of benthic foraminifers. To work out living faunal associations, standing stock and diversity, separate analyses of living (Rose Bengal stained) and dead foraminifers were carried out for the sediment surface. The size fractions between 63 and 125 µm and >125 µm were counted separately to allow comparison with former Arctic studies and with studies from the adjacent Norwegian-Greenland Sea, Barents Sea and the North Atlantic Ocean. Benthic foraminiferal associations are mainly controlled by the availability of food, and competition for food, while water mass characteristics, bottom current activity, substrate composition, and water depth are of minor importance. Off Spitsbergen in seasonally ice-free areas, high primary production rates are reflected by high standing stocks, high diversities, and foraminiferal associations (>125 µm) that are similar to those of the Norwegian-Greenland Sea. Generally, in seasonally ice-free areas standing stock and diversity increase with increasing food supply. In the central Arctic Ocean, the oligotrophic permanently ice-covered areas are dominated by epibenthic species. The limited food availability is reflected by very low standing stocks and low diversities. Most of these foraminiferal associations do not correspond to those of the Norwegian-Greenland Sea. The dominant associations include simple agglutinated species such as Sorosphaerae, Placopsilinellae, Komokiacea and Aschemonellae, as well as small calcareous species such as Stetsonia horvathi and Epistominella arctica. Those of the foraminiferal species that usually thrive under seasonally ice-free conditions in middle bathyal to lower bathyal water depth are found under permanently ice-covered conditions in water depths about 1000 m shallower, if present at all.

Este estudo exploratório, de caráter descritivo, tem como objetivos compreender a relação do Estado com a organização profissional dos assistentes sociais nas diferentes conjunturas sócio-históricas da trajetória da profissão; conhecer o contributo do associativismo sindical e profissional para a organização dos assistentes sociais em Portugal; caraterizar as diversas formas de associativismo profissional e sindical dos profissionais de Serviço Social e compreender a importância da regulação profissional para a categoria. Na trajetória do Serviço Social no nosso país, identificámos várias estruturas associativas desde os anos 50 do século XX. Apesar dessa diversidade ao nível da organização profissional, nos últimos anos tem sido o projeto de constituição da ordem o que tem congregado os profissionais de Serviço Social, embora de forma fragmentada. Em Portugal não existe um estatuto jurídico de regulação da profissão de assistente social, sendo do interesse dos profissionais, utentes e sociedade que o mesmo seja efetivado. A criação de uma ordem profissional poderá vir a fortalecer o trabalho dos profissionais de Serviço Social, bem como proteger e regulamentar o exercício profissional e a formação académica. Com a erosão do Estado Social, as relações de trabalho tendem a ser desregulamentadas e flexibilizadas, subsistindo a precariedade e o desemprego. O enfrentamento a estas questões por parte do movimento associativo é ténue e a sua não articulação fragiliza a proteção dos profissionais, como indiciam a subsistente ausência da constituição da ordem profissional e a extinção do Sindicato Nacional de Profissionais de Serviço Social, apesar do ressurgimento do associativismo sindical durante o presente ano (2013). As condições atuais diferem das existentes aquando do processo de obtenção da licenciatura e estruturação e implementação das carreiras profissionais de Serviço Social que potenciaram e galvanizaram os assistentes sociais. A categoria profissional apresenta-se desmobilizada e com pouco poder reivindicativo, e as associações profissionais e sindicais vivem com constrangimentos financeiros, funcionando em regime de voluntariado, o que denota a insipiência da sua estrutura organizativa. A atual conjuntura justificaria uma maior convergência, debate e processos de resistência por parte das estruturas associativas face ao agravamento de políticas baseadas na austeridade, que têm reflexos no mercado de trabalho, formação e organização profissional. Parece justificar-se a existência de estratégias articuladas com maior clareza sobre o projeto para a categoria, apostando num debate que se faça com os seus diversos intervenientes. Desta forma, o associativismo poderá constituir uma alavanca que confira maior dinamismo às suas estruturas organizacionais, maior visibilidade e presença pública da categoria, mas também uma maior solidez das suas organizações, que não sendo corporativas ou elitistas, salientem o primado da ética do serviço sobre a ética do ganho. / This descriptive exploratory study aims to understand the relationship between the State and the professional organisation of the social workers in the different social-historical situations of the profession course; to know the contribute of the unions and professional membership drive to the organisation of the social workers in Portugal; to characterise the several ways of the social workers’ professional and union membership drive and to understand the importance of the professional regulation for the area. In the Social Service trajectory in our country, we have identified several associative structures since the 1950s. Despite this diversity concerning the professional organisation, the project of constituting the professional order has been responsible for the social workers’ congregation in the past years, although in a fragmented way. In Portugal, there is not a legal status of regulation of the social workers’ profession, and it is of the interest of the professionals, users and society that this may be brought about. The creation of a professional order may strengthen the activity of the social workers, as well as it may protect and regulate the profession exercise and the university education. With the Social State’s erosion, the work relationships tend to be deregulated and softened, persisting the job insecurity and the unemployment. The associative movement does not strongly face these issues, and its non-articulation weakens the professionals’ protection, as the permanent absence of the professional order creation and the extinction of the National Social Workers Union show, despite the reappearance of the union membership drive during the present year (2013). The current conditions are not equal to the ones existent in the process of obtaining the university degree and the structuring and implementing of professional careers in the Social Service area, which have strengthened and galvanised the social workers. The professional category is not mobilised and it has few claimable power; the professional and unions’ associations live with financial problems, functioning in a volunteering regime, which shows the insipience of its organisation structure. The current situation would justify a bigger convergence, debate and resistance processes on behalf of the associative structures regarding the worsening of policies based on austerity – this has consequences in the work market, training and professional organisation. It seems to be pertinent the existence of strategies articulated in a clearer way about the project for this professional area, investing in a debate among its several participants. Therefore, the professional membership drive may constitute a lever that can give more dynamism to its organisational structures, a bigger visibility and public presence of the area, but also a stronger solidity in its organisations which, being not corporative or elitist, may highlight the service’s ethics over the profit’s ethics.

L’obésité est de nos jours un problème croissant à travers le monde. La morbidité qui y est associée est surtout reliée au développement des différentes composantes du syndrome métabolique (SMet), une constellation de facteurs de risque regroupant l’hypertension, la dyslipidémie (concentration faible de cholestérol des lipoprotéines à haute densité (C-HDL) et élevée de triglycérides (TG)), l’hyperglycémie et l’obésité. Cependant, certains sujets obèses demeurent métaboliquement sains. Les facteurs génétiques joueraient donc un rôle important dans le développement de l’obésité et de ses complications. Les facteurs épigénétiques semblent également y avoir des effets. L’analyse de tissu adipeux viscéral (TAV) a donc été réalisée pour mener à la découverte de plusieurs gènes différentiellement exprimés et méthylés entre les obèses atteints et non atteints par le SMet. Les deux gènes candidats NMT1 et DGKZ font partie de ce groupe et leurs associations avec les composantes du SMet ont été testées. Leurs niveaux de méthylation et d’expression génique ont aussi été analysés.

Partimos do pressuposto que a universidade pública é um bem do povo e deve servir aos interesses da sociedade, sobretudo aos interesses daqueles cuja vida é ameaçada mediante as condições desiguais sob as quais a sociedade capitalista se funda. Entendemos que a extensão universitária é uma atividade da universidade e deve, como ensino e pesquisa, ser reconhecida como produtora de conhecimentos e não por trabalhos assistenciais, como se caracteriza, na realidade concreta, a extensão universitária analisada nesta dissertação. Com base nisso, o trabalho que se segue discorre sobre a relação de dependência das associações populares, ligadas ao movimento da economia popular solidária à extensão da Universidade Federal do Rio Grande – FURG, especificamente aquela realizada pelo Núcleo de Desenvolvimento Social e Econômico – NUDESE-FURG, da região de Rio GrandeRS. O objetivo do trabalho foi conhecer a relação entre o núcleo e as associações, problematizando-a com base em alguns princípios da Educação Ambiental Crítica (diálogo, totalidade, relação teoria/prática e participação social). O referencial que sustenta o trabalho articula autores da sociologia do trabalho, economia da educação, ecologia política, geografia crítica, todos, de alguma forma, ligados ao materialismo histórico como perspectiva de análise. O trabalho se caracteriza como um estudo de caso, onde os principais recursos perpassaram pela análise de documentos e, fundamentalmente, as entrevistas gravadas e transcritas na íntegra, pelas quais nosso estudo se baseia. A análise do material foi feita a partir dos pressupostos da análise crítica do discurso, a qual busca entrelaçar os pronunciamentos dos sujeitos com a totalidade social na qual o discurso está inscrito, possibilitando o alcance do significado concreto. O estudo demonstra que a extensão universitária desenvolvida pelo NUDESE-FURG tem características assistencialistas, cuja consequência prática é a realização de atividades para os trabalhadores associados (principalmente elaboração e gestão de projetos), impedindo que as associações desenvolvam suas ações sem depender do núcleo. Além disso, ao assumir recursos financeiros oriundos de projetos (via editais), as associações apenas transferem para o Estado a condição de dependência do intermediário, o que não extingue o problema, mas reafirma-o. Por isso, entendemos que a Educação Ambiental Crítica oferece, por meio dos princípios que utilizamos, um instrumento crítico importante ao estudo de processos e políticas que buscam a emancipação dos sujeitos. Isso porque, também, ao reconhecer a crise socioambiental que vivemos, fruto do modo de produção capitalista, dos conflitos existentes na sociedade (portanto dos diferentes interesses, concepções e valores em disputa), pela apropriação da riqueza produzida, podem-se possibilitar conhecimentos úteis dos trabalhadores das associações. Para que isso aconteça, defendemos o encontro da extensão universitária do NUDESE-FURG com a Educação Ambiental Crítica, caso a emancipação, de fato, esteja no horizonte das práticas deste núcleo, já que pelo estudo, nesta pesquisa, predomina dependência de tais grupos do NUDESE-FURG.

Trinitrotoluene in the purification step (TNT) produced in industries, are carried out two washes at the end of the process. The first wash is done with vaporized water, which originates from the first effluent called yellow water, then the second washing with the use of sodium sulfite is performed (Na2SO3), generating a second effluent red water. This study aimed to study the individual effects, as well as the association of heterogeneous photocatalysis using TiO2 and biological treatment in air lift reactor using activated sludge (bacterial biomass) for the remediation of wastewater contaminated with nitroaromatic compounds in order to reduce toxicity and adjust the legal parameters according to regulatory agencies for disposal in waterways. The photocatalytic treatment was conducted by factorial design obtaining the best reaction conditions (pH 6.5 and concentration of TiO2 0.1 gL-1), with best results obtained at 360 minutes of reaction, reducing the absorbance 97.00%, 94.20% of the chemical oxygen demand (COD), 67.70% of total phenols, as well as a total reduction of observed peaks and assigned to nitroaromatic compounds by high-performance liquid chromatography. In the biological treatment, there was a 53.40% reduction in absorbance at 275 nm 10.00% 36.00% COD and total phenols in a short time (3 days), while for extended periods (48 days) there was an antagonistic influence on the results so that was the elevation of these parameters (COD and total phenols) instead of reducing. Chromatographic analysis confirmed the effectiveness of the biological degradation by reducing the peaks corresponding to compounds DNT and TNT. The Association of photocatalytic and biological treatments decreased results in the order of 91.10% absorbance, 70.26% of total phenols and 88.87% of COD. While the combination of biological and photocatalytic treatments generated relatively lower efficiencies, with 77.30% of absorbance reduction, 62.10% reduction of total phenols and a decrease of 87.00% of COD. In general, when comparing the chemical and biological processes in isolation, the photocatalytic treatment showed the best results. However, comparing the results of isolation and established associations, the association biological x photocatalysis showed more promising results in the treatment of red water effluent.

A Career According to Young People, or a New Career Paradigm in the Dissonant Labour Market is an attempt at answering a question about an extent to which a narrative surrounding the specific features of the postmodern careers has been shared by the young adults who, being in the process of moving from the educational to the labour markets, have experienced these changes, to what extent they have internalised the career patterns emerging in the free-market reality that are different from those existent in Poland twenty-five years ago, and about what (new?) career paradigm is developed by the students. The paper presents preliminary results of a sampling carried out among young university students of the humanities who expressed their opinions on how vocational careers are defined and what associations they evoke. The article moreover provides personal examples of career development and discusses vocational catalysts and inhibitors of a career. The young university students did not, however, fully internalise the postmodern patterns of the mosaic careers prevailing in the competitive labour market, and simultaneously noticed a number of ambivalences and dissonances present in this market reality.

Agroforestry is considered nowadays as a sustainable form of land management that is being promoted by different global institutions like FAO and its Global Alliance Smart Climate Agriculture to mitigate and adaptate to Climate change. The European Commission through the protection of landscape features, greening and Rural Development Programs is promoting the essential presence of woody vegetation across Europe, but in a way that is difficult to recognize by farmers. AGROFE and AGFORWARD projects are both demonstrating the important value of Agroforestry at European level, which together with EURAF are pushing European Commission to include measures enhancing Agroforestry. However, there is a need of a European Agroforestry Strategy that recognizes the drawbacks of Agroforestry to be implemented at European level. This strategy should include the main mechanisms to show farmers how to implement it and at the same time to get funded for the important ecosystem services that they provide when implementing agroforestry. AGFORWARD project has identified the main agroforestry practices in Europe, highlighting silvopasture, but showing the importance that others forms of agroforestry have to play like homegardens with multipurpose trees, or the adequate improvement of fallow lands where woody vegetation can enhance the levels of organic matter in the soil if adequately managed. AGFORWARD also shows the lack of information of the real implementation of agroforestry practices like forest farming, in spite of the important productive and ecosystem benefits it provides. EURAF through the participation in the different civil dialogue groups (CAP, Direct Payments and Greening, Forestry and Cork, Organic Farming, Arable, Environment and Climate Change and Rural Development) has included and promoted agroforestry within the European Agenda. The role of Agroforestry has been also enhanced in the Groups of experts of European Structural and Investments funds and as part of the European Network for Rural Development and its derived groups: innovation, evaluation and CLLD/LEADER. EURAF is pleased to announce that Agroforestry will be discussed as part of a focus group of the European Innovation Partnership, so, apply and join the group. This book represents the lastest findings on agroforestry in Europe, integrating the participation of researchers but also policy makers and farmers and farmers' associations. It was a pleasure for EURAF to integrate all this needed knowledge to be disseminated at European levels. On behalf of EURAF, I wish all of you a successful meeting and invite you to strengthen agroforestry within the different European Union countries when you go back home. Rosa Mosquera-LOSADA President of EURAF
