Mulberry (Morus nigra L.) is a fruit with a great potential for technological uses, which could be employed to manufacture of syrups, ice cream, candies, yoghurts, beverages, jam, etc. Only the leaf from mulberry trees is commercially used for silkworm feeding. This tree is cultivated on many agricultural environments such as small rural proprieties and settlements. Small farmers waste a great amount of their production for not knowing about mulberry technology. Thus, the objective of this work was to access extraction yield and physical-chemical properties of mulberry whole juice from ripe, green and a mixture of both by using press and depulper. Statistical analysis of results was carried by media and standard deviation calculations. 173 kg of mulberry were picked being 49.31% ripe and 50.68% green. Press delivered greater extraction yield of whole juice (80.50% to 81.60%) when compared to press (71.43% to 77.50%). Whole juice obtained from both equipments has shown the following values: soluble solids 7.45% - 12.11%, titrable acidity 0.45 – 1.23%, ratio 6.03 – 26.84, pH 3.69 – 4.35, total reducing sugar 4.05% – 9.96%, reducing sugar 3.95% - 9.15%, sucrose 0.00% - 0.04%, turbidity 221.25 NTU - >4,000 NTU. Whole juices obtained from both equipments has shown similar physical-chemical characteristics except turbidity. The authors concluded that press was the best extraction equipment due to its greater yield and whole juice quality regarding turbidity

Os frugívoros desempenham papel fundamental na manutenção das florestas ao dispersarem as sementes dos frutos que consomem. Dentre as aves tropicais, a família Trogonidae é uma importante representante de tal relação ecológica e por serem sensíveis a alterações no ambiente, são bioindicadores da qualidade do habitat. O presente trabalho teve por objetivo descrever o comportamento de forrageamento de Trogon surrucura no Parque Estadual da Cantareira, São Paulo, e registrar e levantar na literatura os itens alimentares consumidos pela espécie. Foi observado que T. surrucura capturou presas preferencialmente em folhas verdes, utilizou-se da manobra investir-pairar na maior parte dos eventos de forrageamento, e não retornou aos poleiros de partida em 92% dos casos. Entre os itens alimentares levantados, os mais registrados foram artrópodes (principalmente insetos da família Tettigoniidae e lepidópteros), seguidos de frutos (Eugenia uniflora, Euterpe edulis entre outros), além de vertebrados (anuros da família Hylidae) e flores (do gênero Ipomoea). Como já citado em literatura, a espécie mostrou-se comum na área de estudo

Currently there are two car models that use electricity in their propulsion systems, the electric vehicle and the hybrid electric vehicle. The electric vehicles are classified as vehicles that use electric motors in their propulsion system and batteries as a power source, on the other hand, the hybrid vehicles are classified as vehicles that use both electric motors and internal combustion engines in their propulsion system, using both batteries and líquid fuels as a power source. The main goal of this work is to analyze the characteristics of electric and hybrid electric vehicles and demonstrate the unfeasibility of the electric vehicle in the current economic, political, energetic and environmental brazilian scenario, for this purpose it was realized a study about the current brazilian situation regarding to electricity generation, current conservation status of road network, lack of electrical infrastructure for charging batteries, national lithium reserves, environmental characteristics, tax incentives, economic scenario, oil market and political positioning related to the implantation of electric or hybrid electric fleets in nacional territory. The operational characteristics analysis of electric and hybrid electric vehicles in this current scenario leads to the conclusion that currently a growth of electric vehicles fleets on a national scale is totally impractical in the Brazil, Thus, the introduction of green vehicles probably will occur primarily with hybrid electric models, motivated mainly due the bigger autonomy of this models compared to electric models, lower cost of hybrid electric models compared to electric models, factors related to the lack of recharging infrastructure and also factors related to political positioning

The objective of this work was to evaluate the utilization by corn plants of P from triple superphosphate fertilizer labeled with P-32 (P-32-TSP), and of P from soil as affected by N rates and by the green manures (GM) sunn hemp (Crotalaria juncea) and millet (Pennisetum glaucum). The experiment was carried out using pots filled with 5 kg Oxisol (Rhodic Hapludox). A completely randomized design was used, in a 4x4x2 factorial arrangement, with four replicates. The treatments were: four P rates as TSP (0, 0.175, 0.350, and 0.700 g P per pot); four N rates as urea (0, 0.75, 1.50, and 2.25 g N per pot); and sunn hemp or millet as green manure. The additions of N and P by the GM were taken into account. After grain physiologic maturation, corn dry matter, P contents, accumulated P, and P recovery in the different treatments were measured. P-32-TSP recovery by corn increased with N increasing rates, and decreased with increasing rates of P-32-TSP. The mineral fertilizer provides most of the accumulated P by corn plants. The recovery of P-32-TSP by corn was 13.12% in average. The green manure species influence the assimilation of P-32-TSP by the plants.

Objetivo Este estudo teve como objetivo avaliar a variabilidade e a frequência do consumo alimentar, o estado nutricional e o nível de atividade física em uma comunidade universitária brasileira. Métodos A amostra constitui-se de 303 voluntários (130 homens e 173 mulheres) pertencentes à comunidade universitária do interior de São Paulo e avaliada por meio da disponibilização pela Internet do Questionário de Frequência Alimentar do International Physical Activity Questionaire e por meio da coleta da descrição autorreferida do peso e da altura. Foi realizada análise descritiva dos dados, análise de frequência alimentar e teste do coeficiente de correlação de Spearman. Resultados Foram observados inadequação dos hábitos alimentares, sobrepeso e obesidade na amostra estudada. As correlações entre os grupos alimentares apresentaram valores de magnitude maiores no grupo de mulheres que se alimentam de forma mais adequada do que os homens, mas não foram observadas diferenças entre os sexos no nível de atividade física. Não houve correlação significativa entre grupos de alimentos consumidos, índice de massa corporal e nível de atividade física em ambos os sexos. Conclusão A comunidade universitária estudada apresentou baixo consumo de frutas, legumes e verduras, bem como consumo insuficiente de alimentos do grupo de cereais e leguminosas.

Obesity is a chronic disease characterized by increased accumulation of body fat. We evaluated the socioeconomic aspects, body composition, risk of metabolic complications associated with obesity, eating habits and lifestyle in both women and men adults and elderly with body mass index (BMI) 40 kg/m(2). Among the subjects studied, 79% (n = 32) are female, 5% (n = 2) smokers, 39% (n = 16) use alcohol and only 24% (n = 10) are practitioners of physical exercise. The higher food intake was breads, followed by rice. The daily intake of fruits and vegetables is low. Positive correlation between consumption of sugar and BMI and abdominal circumference (AC) was observed. In summary, was found that morbidly obese patients that looking for nutritional counseling presents increased body fat, poor eating habits and sedentary lifestyle.
