Chlorophyll a fluorescence parameters and photosynthetic pigments content in leaves of broccoli (Brassica oleracea L. var.italica) cv. ‘Monaco’ F1 and cauliflower (Brassica oleracea L. var. botrytis) cv. ‘Bruce’ F1 transplants were analyzed to investigatethe effects of chilling temperatures (6 and 10 °C) and the exposure length (1 or 2 weeks) on the photosynthetic apparatuscondition in 3-year experiment. Data were compared to control plants exposed to 14 °C for 1 and 2 weeks. The lowest valuesof maximum quantum efficiency of photosystem II (Fv/Fm) and the performance index (PI) were observed in cauliflowerchilled at 6 °C for 2 weeks. This was not accompanied by any substantial reduction in chlorophylls concentration, however,significant correlations between Fv/Fm or PI and chlorophylls content in cauliflower leaves were found. There was no negativeeffects of chilling on photosynthetic activity and chlorophyll content in broccoli leaves, the amount of carotenoids significantlyincreased in the broccoli chilled for 2 weeks in 6 °C. The chlorophyll a fluorescence indices and accelerated carotenoidssynthesis showed that broccoli had less vulnerable photosynthetic apparatus to stress-induced temperatures and more efficientprotection mechanisms in comparison to cauliflower transplants.

Vitis vinifera L. cv. â€˜Agiorgitikoâ€™ is one of the most important red grape varieties of Greece, cultivated almost exclusively in the region of Nemea in north-eastern Peloponnese. This work aimed to study the influence of some commonly applied viticultural practices on the polyphenolic composition of â€˜Agiorgitikoâ€™. Leaf removal at veraison, irrigation, and a combination of both, were applied and the phenolic content of the grapes and of the produced wines was compared. The results showed that leaf removal decreased berry size, enhanced total anthocyanin, total phenol and malvidin 3-O-monoglucoside accumulation in skins and increased the amount of extractable anthocyanins in the juice. The combination of irrigation and leaf removal caused a significant increase in total phenols in the skin and in the amount of extractable anthocyanins in juice. As far as the produced wines were concerned, color intensity, tannin content and total polyphenols were increased due to leaf removal. Both irrigation and leaf removal resulted in wines with the highest concentration of malvidin 3-O-monoglucoside, although neither practice resulted in any significant difference in anthocyanin concentration of the wines. Vines where only irrigation was applied produced berries with reduced extractable anthocyanins, increased seed total phenols and lower wine total tannins. The study showed that increasing cluster sun exposure of â€˜Agiorgitikoâ€™ vines may be, overall, beneficial to the quality of the produced wine.

The effects of different temperatures (20 Â°C, 25 Â°C, 30 Â°C, 35 Â°C and photoperiod 26 Â°C/21 Â°C), types of soil (sand and loam) and soil herbicides (oxyfluorfen, terbuthylazine and mesotrione) on seed germination percentage, germination rate, as well as seedling length and weight of common milkweed (Asclepias syriaca L.) were examined. Over a period of ten days, germinated seeds were counted daily, and seedling length and weight were measured on the final day and germination rate calculated. The results indicated that temperature was the factor that significantly affected the percentage of germinated seeds of common milkweed, seedling length and germination rate, while it had less influence on seedling weight. The results showed that the alternating day/night temperature of 26 Â°C/21 Â°C also had a significant impact as the percentage of germinated seeds was the highest at that temperature on both soil types (sand: 71.3%; loam: 61.3%). Data regarding the herbicides tested (oxyfluorfen, terbuthylazine and mesotrione) showed decreasing germination percentage and seedling length with increasing herbicide concentrations on both soil types. Their effect was weakest on seedling weight. Tested herbicides are usable in control of common milkweed at the stages of germination and early establishment.

Pickling cucumbers are highly important both for fresh consumption and for canning industry. This study aimed to compare differences in yield and quality of eight pickling cucumber cultivars, including ‘Cor 12004’, ‘IGG 2010’, ‘IGG 2020’, ‘SM 5322’, ‘SM 5323’, ‘Zayin 201’, ‘Zayin 175201’ and ‘Trilogy’. The cucumber cultivars were laid out in a high tunnel crop and evaluated for vegetative traits (i.e. vine length, nodes per vine and branches per vine), yield attributes (i.e. fruits per main stem, average weight of fruit and fruits weight per plant) and fruits quality components (nitrate, phosphate and potassium mg kg-1). The results showed significant differences (P<0.05) in vegetative traits and yield attributes among cultivars. The analysis of correlation coefficients revealed that total yield (kg ha-1) was positively correlated with two out of three vegetative traits (with exception nodes per plant) and with all yield attributes. The highest total yield (101.17 t ha-1) was reached by ‘SM 5322’ cultivar, followed by the ‘IGG 2010’ and ‘SM 5323’ cultivars. The nitrates content in fruits, assessed on three categories of length (6-9 cm, 9-12 cm and >12 cm), revealed a declining value with increase in the cucumber length. The study findings suggest that irrespective of the cultivar, the amount of nitrate was higher in shorter cucumbers (6-9 cm length) although allrecorded values (between 192.7 and 364.3 mg kg-1 fresh matter) being under maximum accepted limit concentrations. The amount of phosphate was higher in medium to long cucumbers, while the amount of potassium was higher in shorter cucumbers.

Published: March 2017

The pepper producers in the Republic of Macedonia have used drip irrigation systems to increase yield in recent years, but more research is still needed, related to irrigation scheduling and precise requirement of nitrogen fertilizer to maximise pepper yield. Therefore, a two year experiment was conducted in a plastic house to determine the nitrogen fertilizer use efficiency (NFUE) and yield potential of pruned pepper as affected by irrigation and fertilization regime. Four experimental treatments were applied in this study. Three of the treatments were drip fertigated (DF1, DF2, DF3), while the fourth treatment was furrow irrigated with conventional fertilization (Ã˜B). The labelled urea with 1% concentration of a stable isotope of nitrogen (15N) was applied for determination of NFUE. The results of this study clearly showed that increased NFUE and pepper yield depend on irrigation and fertilization regime. Namely, NFUE was significantly increased with the application of nitrogen fertilizer through drip irrigation system as compared to conventional fertilization with furrow irrigation. Also, drip fertigation frequency positively affects percentage increase of NFUE. Furthermore, our results showed that drip fertigation treatments resulted in significantly higher pepper yields in comparison to conventional fertilization. Also, drip fertigation frequency at four and two days (DF2 and DF1) resulted in higher yields when compared with drip fertigation scheduled by using tensiometers (DF3). Generally, to reach acceptable pepper yield with high NFUE, we recommend drip fertigation with a frequency of two to four days combined with two main shoots of pruned pepper in order to increase farmerâ€™s income and to minimize the environmental impact.

Turkey has rich wild apricot populations and all Turkish apricot cultivars were previously selected among wild apricots. On this background for apricot breeding, six new late flowering dried apricot genotypes were taken under study, along with wide spread cv. 'Hacihaliloglu'; all genotypes were examined in terms of volatile compounds using Headspace-Solid Phase Micro Extraction - Mass Spectrometry (HSSPME/GC/MS) techniques. The most important volatiles of apricot genotypes were aldehydes, alcohols, esters, terpenes, ketones and acids. Among these compounds, ethanol, hexanal, 3-carene, squalene, acetic acid, tetradecaonic acid, pentadecaonic acid, octadecaonic acid, n- hexadecaonic acid and 1-hdroxy-2-propanone were present in all genotypes studied at certain levels. In general, total concentrations of aroma compounds were higher in some promising genotypes under study than within 'Hacihaliloglu' cultivar, except total alcohol compound (53.33%). Volatile compounds, particularly esters, were the major contributors to fruity, floral and pleasant fruit flavours. The highest esters' compound contents were detected in 'N95' (9.2%) and 'N57' (2.18%) genotypes, while 'Hacihaliloglu' had 1.61% ester compounds. Lacton (Î³-decalactone) was a key aroma compound of apricot. Î³-decalactone was detected ranging between 0.4-1.13% in all genotypes, except cv. 'Hacihaliloglu'. The hereby obtained results showed that the volatile composition depended largely upon the apricot genotypes, moment of harvest, growing conditions and cultural applications that may all affect fruit quality. These results represent valuable starting points for apricot breeding programs.

Published: March 2017

Salinity is a major abiotic stress worldwide, which causes a tremendous loss in the quality and quantity of agricultural products. In order to identify defense mechanisms to salinity-induced stress, a two-dimensional electrophoresis approach was used to investigate proteins achieved from canola cultivar â€˜Option 500â€™ seedlings, after plants had been treated with NaCl. The 300 mmol NaCl treatment caused a significant decrease in fresh and dry weight as well as plant height and increment of proline content compared with control group. There were no significant changes in the quality of catalase and peroxidase activity. Out of 110 repeatable protein spots, 44 were registering change, according to induction factor index. 7 spots were recognized significant at 1% probability level statistically. These proteins were involved in energy production, ROS scavenging and suppressor, and those involved in photosynthesis. Production of chloroplastic fructose-bisphosphate aldolase enzyme along with carbohydrate metabolisms of Kelvin cycle and glycolysis increases under salinity condition. The amount of Cu/Zn SOD in chloroplast reduces in response to salinity which results from an increase in OH- radicals. Expression of photosynthesis proteins have been reduced probably as a consequence of the drop in osmotic pressure resulted from water scarcity and stomata closure, which reduces the availability of Co2.
Organic Seed Hydration-Dehydration Techniques Improve Seedling Quality of Organic Tomatoes

Published: March 2017

The use of pre-sowing organic hydration-dehydration techniques to improve quality and performance of organic seeds has already been lacking in the literature as well as in the organic farming regulations of different countries. Hence, this study was conducted to investigate the effects of organic hydration (hydropriming and organic priming) and dehydration treatments on germination and early seedling growth in organic tomato seeds. Following each priming treatment, the seeds were surface dried and divided into two sub-groups. First part of the seeds was taken to the germination tests immediately while the second part was dried back until the original seed moisture content was reached before the germination tests were set up. Then, responses of organic tomato seeds to organic hydration and dehydration treatments were observed on the bases of viability (normal germination rate) and different vigour parameters such as mean germination time, germination index, seedling dry weight and seedling vigour index. When the overall data were assessed, the best results were obtained from the hydropriming and organic priming with 250 ppm seaweed extract solution followed by both dehydration treatments in organic tomato seeds. Consequently, these results suggested that hydropriming and organic priming could be used both in seed and seedling industries to improve organic seed quality and performance. Furthermore, the results indicated that the addition of these organic hydration-dehydration protocols to the current procedures of the regulations of organic tomato production could be a useful strategy.Key words:Â Lycopersicon esculentum, Ascophyllum nodosum, hydropriming, organic priming, seed viability, seed vigour

Climate change is one of the greatest environmental, economic and social challenges in the history of mankind and nowadays is considered as the biggest environmental problem of the world. Climate change has a significant global impact and therefore Greece has to deal with its effects as well. Agriculture has been unfavourably affected in recent years, as the current and anticipated conditions in many cases seem to be rather prohibitive for the prosperity of the cultivated crops. On the contrary, these new conditions have made it possible for new plant species previously cultivated only in subtropical regions, to thrive in Greece. Moreover, economic reasons would make it rather necessary for the agricultural industry to cultivate alternative crops, which are thoroughly analysed in the present study. Based on Heating Degree Days (HDD) Greece is divided into four climatic zones. The variations in the mean maximum, mean minimum and mean temperature in each climate zone as well as the rainfall over the last 50 years (from 1964 to 2013) are reviewed in this paper. The outcome of this research is that it is not feasible for the studied alternative crops to thrive in all climate zones or vice versa. However, some of them and particularly crops such as quinoa, maca, psyllium, chia, cassava and pecan can be cultivated in all climate zones. It has also to be noted that adequate water is necessary for almost all the examined crops in order to achieve optimal growth and yield and therefore irrigations are rather necessary for specific species and climate zones.

â€˜Wonderfulâ€™ pomegranate arils were treated with 0.5% and 1% of calcium chloride, 0.5% and 1% of calcium lactate, and salicylic acid (1 and 2 mM), then treated and untreated (control) arils packaged in clean (sterilized) plastic containers. Fresh produce was then stored at 5Â±1 â„ƒ. Assessment of arils quality was carried out at 3-day intervals by evaluating the following quality parameters: appearance, decay, off odor, flavor, total soluble solids, acidity, anthocyanin and vitamin C content, firmness, colour development (L* value and hue angle), and microbial load. Pomegranate arils treated with salicylic acid, calcium chloride, and calcium lactate maintained a general good quality and appearance up to 12 days of storage at 5Â±1 â„ƒ, with no visible decay and off odor development. The total microbial population was lower in arils treated with salicylic acid, in comparison to treatments with calcium chloride, calcium lactate and control arils. All treatments scored above the limit of marketability, maintaining good quality of fresh-cut produce during storage. However, the use of salicylic acid and calcium chloride helped to keep a better overall quality of arils at the end of the 12-day storage at 5Â±1 â„ƒ.

Published: March 2017

The paper investigates the main changes that have taken place in the Romanian fruits and vegetables supply chain over the past twenty years. Its sustainability is assessed using time-series data from different official and private data-bases applying statistic research methods. Results showed that the Romanian supply chain is dominated in terms of both inputs used and offer, by imports originating from different EU countries. The local subsistence and semi-subsistence farms cannot provide enough qualitative and quantitative products such as to penetrate the supermarkets, the main players from the market. Agritourism, a potential niche market, was investigated using sampling techniques. The guesthouses from one of the most important ecotourism destinations where assessed by face-to-face interviews. Results showed that even such short-marketing chains are unsustainable tools for the fresh fruits and vegetables products sectors. The lack of governance for the local producers does not allow them to enter on such niche market. All this findings can provide important incentives for better future targeted sectorial agricultural policies.

Published: March 2017

Dumontinia tuberosa fungus was observed in different stages of development growing on the roots of Ranunculus ficaria in Cluj-Napoca (Romania), over the course of several years. It is not frequently encountered, therefore, we decided that will be interesting to cultivate it on nutritive medium, and to use the morphological data and the colonyâ€™s characteristics to identify the fungus. The identity of the fungus was reaffirmed through a molecular analysis of sclerotium DNA sequences. A new favourable nutritive medium for the growth and development of the fungus is proposed. The morphology and ultrastructure of the fungus were examined by light and electron microscopy, and micrographs of the relevant details are provided. Differences between the ultrastructural characteristics of sclerotium, apothecium stipe, ascospores, asci and paraphyses are presented and discussed. Intercellular spaces were identified in sclerotium and apothecium stipe and the paraphyses. Asci and ascospores were found to be covered by a sticky mucilage. The ultrastructural characteristics of the aforementioned tissues are presented for different developmental stages. Additionally, the main food stores of the fungus, represented by glycogen, lipids and proteins, are located and described along with other characteristic compounds, such as melanin pigment and a glucan extracellular matrix. The present study complements prior information on the worldwide distribution of this rare species in nature and contributes new findings regarding its morphological and ultrastructural characteristics.

Published: March 2017

In recent years, there has been a growing trend towards cultivating leafy vegetables in hydroponic systems. Floating system is an alternative hydroponic system suitable for the production of baby vegetable products, ready-to eat salads and minimally processed leafy vegetables. However, the implementation of this system for the production of fully grown leafy vegetables is not sufficiently studied. The aim of the present study was to examine the potential of floating system as an alternative growing technique of lettuce and rocket plants, as well as the effect of nitrogen (N) application rate (three treatments 100, 150 and 200 mg L-1 of N) on plant physiology, quality and yield during three growing periods. The results showed that increasing the N application rate resulted in an increase of fresh weight of the aerial parts of both lettuce and rocket, while total yield ranged between 12.0 to 41.9 and 8.0 to 30.2 kg m-2 of fresh leaves, for lettuce and rocket, respectively. In addition, increasing the nitrogen rate resulted in higher number of leaves for lettuce and rocket, as well as in a significant increase in the rate of photosynthesis. A similar increase was observed in nitrate, K, Mg and Mn content in the leaves, without however exceeding the permissible limits for nitrates in any case. In conclusion, the use of floating raft technique for lettuce and rocket cultivation in order to produce not only seedlings production or baby products, but also fully grown plants of high quality is highly recommended.

Resumo Os conflitos socioambientais relacionados a empreendimentos extrativos vêm aumentando na América Latina, na medida em que há, nessa região, um crescente incentivo à extração e à exportação de commodities. Nesse contexto, a ação coletiva de contestação funda-se a partir de um enquadramento que marca uma condição comum entre aqueles que são afetados pela mineração, pelo petróleo e por outros grandes empreendimentos extrativos. Isso abre um processo de contestação específico que reúne certos atores, repertórios e reivindicações, os quais constituem dinâmicas de mobilização do direto, haja vista o uso contundente de estratégias legais e judiciais. Este artigo apresenta uma proposta de caracterização dos atores, dos repertórios e dos enquadramentos insurgentes da política dos afetados pelo extrativismo na América Latina. Apresentamos uma explicação fundamentada em aspectos macro, mas com ênfase em elementos microssociológicos. A pesquisa levantou casos de variados países, empregando uma abordagem qualitativa com análise de materiais documentais e observação participante.

ABSTRACT Objective: To evaluate the effects of a multi-professional educational program in patients with knee osteoarthritis (KOA) . Methods: Prospective randomized controlled trial with 195 KOA patients. One group was submitted to two-day lectures and received educational material about KOA (Class group), and the control group received the educational material only. Patients were evaluated at baseline, twelve and 24 months. At evaluation, patients answered pain and functional questionnaires (WOMAC, Lequesne, VAS and SF-36); reported the intensity of exercise per week; measured the body fat percentage, weight and height to estimate body mass index (BMI); and performed Timed Up & Go (TUG) and Five-Times-Sit-to-Stand (FTSST) tests . Results: The groups presented similar results in all time points with respect to pain (VAS and WOMAC pain), WOMAC, BMI and body fat percentage (p>0.05). The Class group exhibited improved function according to the Lequesne questionnaire, whereas the control group worsened (p=0.02) during follow-up (p<0.02). TUG (p=0.01) and FTSST (p<0.001) improved in the Class group. A higher percentage of patients in the Class group performed regular physical activity (p=0.045) . Conclusions: The educational program with classes improved the consistency of physical activity and the subjective and objective function of patients with KOA.

ABSTRACT Objective: To evaluate the hormonal profile of patients with adolescent idiopathic scoliosis (AIS) and its relationship to the severity of the curvature and quality of life . Method: Patients with scoliosis (Cobb angle above 10°), of both genders, diagnosed after 10 years of age were included, excluding those who presented other condition that could lead to scoliosis. Serum levels of 25-hydroxyvitamin D (25-OHD), cortisol and gastrin were correlated with Cobb angle and quality of life, measured by the SRS-30 questionnaire . Results: The levels of 25-OHD decreased in 97% of patients. There was an inverse relationship between gastrin levels and quality of life (p = 0.016). Moreover, there was an inverse correlation between the value of Cobb angle and quality of life (p = 0.036). There were no changes in cortisol levels. There was no correlation between Cobb angle and any of the hormones measured . Conclusion: The patients had levels of 25-OHD diminished, strengthening the hypothesis of its involvement in the development of AIS. This study also suggests that increased gastrin levels may be associated with a worse quality of life in patients with AIS. Level of Evidence II, Diagnostic Study.

Resumo O objetivo deste trabalho foi analisar a tendência temporal das internações por condições sensíveis à atenção primária (ICSAP), relacionando-a com os gastos em saúde e com a cobertura da Estratégia Saúde da Família (ESF), no município de São Leopoldo, Rio Grande do Sul, no período de 2003 a 2012. Trata-se de um estudo ecológico de tendência de série temporal. Foram utilizados dados secundários, disponíveis no Sistema de Informações Hospitalares do Sistema Único de Saúde, no Departamento de Atenção Básica e no Sistema de Informações sobre Orçamentos Públicos em Saúde. A análise foi realizada mediante comparação das ICSAP por meio de médias móveis trienais e na regressão de Poisson ou binomial negativa. Não foi observada significância estatística na diminuição dos coeficientes de ICSAP e das despesas com atenção primária. Os gastos em saúde, o gasto per capita e a cobertura da ESF aumentaram significativamente, porém sem relação com as ICSAP. Os resultados encontrados apontaram que, apesar dos incrementos nos investimentos financeiros e na cobertura populacional pela ESF, ambos não alcançaram níveis para garantir cuidados de saúde adequados à população.

O estudo, de natureza qualitativa, contou com a participação de 22 psicólogos. A coleta de dados iniciou com a observação participante de campo do contexto institucional, seguida da entrevista semiestruturada. O método da “Grounded Theory” foi usado na análise das informações facultando integrá-las e categorizá-las. Os resultados demonstraram que o atendimento na rede de Atenção Básica delimita o tratamento de quadros depressivos sob a perspectiva sobretudo biológica; a eleição da psicoterapia individual como principal forma de atendimento remete a práticas tradicionais de atenção aos quadros de depressão; o uso dos dispositivos institucionais e comunitários como parte do projeto terapêutico aponta para ações em saúde mental que contemplam a dimensão psicossocial. Os resultados revelam que a superação dos modelos tradicionais de atendimento à depressão e a construção de formas de atenção que utilizem recursos psicossociais ainda estão em curso, evidenciando que a atenção integral precisa ser mais bem consolidada na Atenção Básica.

Resumo Este artigo resultou de um estudo com o objetivo de determinar o grau de satisfação dos utilizadores com os cuidados prestados nas 125 Unidades de Saúde Familiares (USF) e em algumas das 127 Unidades de Cuidados de Saúde Personalizados (UCSP) da Região de Lisboa e Vale do Tejo (LVT). Foram entregues 20.118 questionários e recebidos 16.965 (89,0% taxa de respostas). O instrumento de recolha de dados utilizado foi o questionário Europep, medindo essencialmente quatro dimensões: cuidados médicos, cuidados não médicos, organização dos cuidados e qualidade das instalações. 65,3% dos respondentes eram mulheres, a média etária atingiu os 50,8 anos, 35% tinham no máximo 6 anos de escolaridade e para 5,2% este tinha sido o seu primeiro contato. Verificou-se um valor médio global de satisfação de 77,4%, superior em relação aos cuidados e à atenção prestados pelos profissionais. As mulheres apresentaram uma satisfação ligeiramente menor do que a dos homens, o mesmo acontecendo aos jovens face aos mais idosos. As pessoas com menos habilitações literárias foram as que apresentaram melhores índices de satisfação. As USF tiveram sempre maior satisfação face às UCSP, com os modelos B com maior satisfação face aos modelos A. Os utilizadores penalizam as unidades com mais de 12 MF e verificou-se uma grande disparidade regional.

Resumo Considerando a trajetória do Rio de Janeiro e da Região de Lisboa no que tange ao fortalecimento dos seus sistemas de saúde para alcance da saúde para todos e da equidade, propôs-se uma análise comparativa da organização da Atenção Primária à Saúde, buscando identificar os avanços desta em termos de coordenação das Redes de Atenção à Saúde. Trata-se de um estudo de caso, de orientação qualitativa e com dimensões avaliativas. Utilizou-se material disponível online, considerando artigos científicos e literatura cinza. Os resultados acenam para compassos diferentes no tocante às RAS, na região de Lisboa, com maior velocidade, até por questões históricas, foi implementado o modelo de APS abrangente e que hoje alcançou grau de maturidade suficiente no que tange à coordenação do seu sistema, enquanto o Rio de Janeiro sofre influências dos resquícios históricos de uma Atenção Primária à Saúde seletiva. O plano de carreira aparece como estratégia para fixação das equipes de saúde. As regiões têm feito apostas fortes nos prontuários eletrônicos e na telemedicina. Depois do estudo, ficam claras as questões históricas, culturais e políticas e jurídicas que acabam por determinar diferenças na APS coordenadora de RAS no Rio de Janeiro e na região de Lisboa.
Evaluation of the feeding preference between the aquatic macrophytes Egeria densa and Chara indica by the invasive mollusk Melanoides tuberculata
Authors: Medeiros E. L. , Henry-Silva G. G.
Published: March 2017

Abstract This study evaluated the feeding preference of the invasive mollusk Melaniudes tuberculata between the aquatic macrophytes Egeria densa and Chara indica. The experiment consisted of twelve experimental units (glass aquariums) each of which contained three liters of water and three compartments. Fragments of E. densa and C. indica were placed in separate compartments within each unit; the third compartment, which did not contain macrophytes, was used as the control. Twenty Melanoides tuberculata individuals were placed in each unit and monitored hourly over the course of 24 hours for preferential movements. Physical and chemical water variables were measured at the beginning and end of the experiment. Habitat complexity was determined through collected macrophyte fragments and determined using the Fractop program. After 24 hours, the highest average number of individuals was observed in the treatment with Chara indica (ten individuals), which differed significantly from the treatment with E. densa (four individuals) and the control treatment (two individuals). The number of individuals between the E. densa and control treatment were similar. M. tuberculata showed a clear feeding preference for C. indica.
O LUGAR DOS GRAFISMOS E DAS REPRESENTAÇÕES NA ARTE PRÉ-COLONIAL AMAZÔNICA
Authors: Gomes Denise Maria Cavalcante
Published: March 2017

Resumo Este artigo discute aspectos formais associados à materialidade dos regimes de figuração da cerâmica ritual de duas culturas pré-coloniais tardias da Amazônia - Santarém (1000-1600 d.C.) e as Estearias do Maranhão (775-1045 d.C.) - cujos objetos se sobressaem pela ênfase nas representações figurativas. Seu propósito é evidenciar a estrutura de ambos os estilos e finalmente refletir sobre os possíveis significados culturais da inversão observada nessas sociedades do passado em relação à arte das sociedades indígenas contemporâneas. Segundo a recente caracterização antropológica, esta última seria marcada por uma tendência geral não representativista que se destaca pela presença do grafismo abstrato, mantendo uma conexão com as cosmologias animistas e perspectivistas dominantes na região. Vistos em detalhe, os exemplos arqueológicos examinados, apesar de indicarem uma tendência oposta ou a preeminência da figuração, apontam a coexistência de ambos os regimes.
Refração luminosa em recipientes preenchidos parcialmente com água: análise de problemas e proposta experimental
Authors: Macedo Junior M. A. V. , Jesus V. L. B. de
Published: March 2017

No presente trabalho discutimos a abordagem utilizada por alguns livros didáticos de física de nível médio sobre o fenômeno da refração luminosa. Nos capítulos introdutórios à refração da luz, imagens de objetos parcialmente imersos em recipientes preenchidos com água, apresentam-se “quebradas” e, em alguns casos, “separadas”, quando vistos lateralmente. Além de caracterizar os livros didáticos dentro de um conjunto de critérios estabelecidos, apresentamos também uma proposta experimental com o intuito de aprofundar a discussão acerca do tema. Usando a lei de Snell-Descartes, mostramos medidas relacionadas às posições das imagens formadas a partir de um canudo parcialmente imerso em diferentes níveis de água para dois tipos de recipientes: um de base circular e outro retangular.

Published: March 2017

En este artículo se calcula la dimensión de Hausdorff-Besicovitch ó dimensión fractal de dos objetos astronómicos, utilizando el método de conteo de cajas. Se utilizaron imágenes obtenidas con el Telescopio Espacial Hubble de las regiones de formación estelar conocidas como Hubble V y Hubble X, localizadas en la galaxia NGC 6822. Los valores de dimensión fractal de estas regiones HII gigantes son comparados con los resultados de otros objetos astronómicos de la misma especie reportados en la literatura. Sugerimos un nuevo esquema de clasificación de regiones HII gigantes basado en esta propiedad.

As sete meninas: reflexões sobre mulheres, experiência e efeitos jarawara
Authors: Maizza Fabiana
Published: March 2017

Resumo A partir de minha etnografia com os Jarawara, povo falante de uma língua Arawá e habitante do médio curso do rio Purus, este artigo visa refletir sobre a festa de saída das meninas em reclusão, o mariná, e seus efeitos na composição de uma agente “levável”. A ideia aqui desenvolvida é que a “sonolência” (nokobisa), o “cansaço” (mama) e a “beleza” (amosa) são formas de ações rituais que visam extrair dos corpos das mulheres suas capacidades de serem “leváveis” (towakama), de “serem carregáveis” (weyena). Essas qualidades estariam igualmente associadas aos xamãs que, após o consumo de rapé, são carregados nas costas de seus filhos-planta e experimentam relações com diversos tipos de seres no neme (a “camada superior”) – seres que também encontram em seus sonhos. Procurarei assim pensar como uma certa noção de agência das mulheres jarawara pode estar vinculada à atividade onírica e ao conhecimento xamânico.
Contrabando de afectos, fugas de capitales y otros desplazamientos. Relaciones de sexo comercial más allá de las fronteras de la prostitución
Authors: Morcillo Santiago
Published: March 2017

Resumen Este artículo aborda los vínculos entre mujeres que ofrecen sexo comercial y sus clientes, enfocando en aquellas relaciones que se cargan de afectos y escapan a los estereotipos de la prostitución. A partir del análisis de entrevistas con mujeres que hacen sexo comercial bajo diferentes modalidades y en tres ciudades de Argentina, se delinean tres tipos de relaciones con diversas formas de arreglos económicos y sexo-afectivos. Desde allí se abre la reflexión sobre los posibles sentidos de los intercambios de sexo comercial más allá de los esquemas dicotómicos.
DELIBERAÇÃO COLETIVA: UMA CONTRIBUIÇÃO CONTEMPORÂNEA DA BIOÉTICA BRASILEIRA PARA AS PRÁTICAS DO SUS
Authors: Gomes Doris , Aparisi Juan Carlos Siurana
Published: March 2017

Resumo Este ensaio teve por objetivo analisar a necessidade de nova excelência profissional pautada na deliberação coletiva, debatendo a ética aplicada às questões de saúde nas experiências de Brasil e Espanha. O funcionamento prático dos comitês de bioética na Espanha avança na constituição do método deliberativo como participação coletiva na decisão profissional, discutindo a importância da democracia deliberativa para a construção de nova civilidade ética. No Brasil, após as primeiras décadas de construção do Sistema Único de Saúde, amplia-se o leque de participação dos profissionais, primeiramente nos conselhos de saúde e, com a resolução CNS n. 196/96, também nos comitês de ética em pesquisa envolvendo seres humanos, aprimorando novas ações afirmativas, de organização e comprometimento coletivo com ampliação da responsabilidade na construção e efetivação das políticas públicas. A deliberação ética adquire centralidade: a decisão profissional que era paternalista e privada em ato é, paulatinamente, ampliada como deliberação coletiva e socialmente ativa, o que sugere a necessidade de uma nova excelência profissional, além do meramente técnico e clínico-individual. A bioética brasileira adquire papel preponderante na transformação da excelência profissional pautada numa solidariedade crítica e no comprometimento com o público-social, em coletivos de deliberação que considerem a qualidade de vida da população.
