This paper ditach the portability and mobility of digital television as opportunities for promotion to the social hospitality. The digital technologies add news concepts to hospitality, converging to the redemption of the social being, integrating and strengthening social ties in the technological space. With the digital television, we may have new forms of sociability, because may be required and assisted in any place, as a result of their actions for portability and mobility, which allows the construction of social ties or an ample concept the hospitality social in public spaces.

The objective of this work was to evaluate the effect of processing two corn hybrids conserved, dry and humid grains, the dry matter (DM) and crude protein (CP) degradability in situ. The particle size was determined and difference was verified in MGD (Medium Geometric Diameter) of processed ingredients. Three sheep were used with rumen canulated, in a completely randomized design, using a factorial outline 2 x 2 x 3, being two corn hybrid, two conservation methods and three processing forms (whole, coarsely and finely ground), with five times of incubation (3, 6, 12, 24 and 48 hours). The fraction A in SDC (silage of dent corn) of DM was superior to GDC (grain of dent corn) in all of the particles size. The ensiling process increased the DM solubility, reducing the fraction B in comparison to dry grain. The values regarding the fractions DP and DE the 5% per hour of the protein, were larger for SDC and GDC, it presents a decreasing when the incubation time advances. The fermentation rate was superior for SDC and GDC. The ensiling process has positive effect in the decreasing of DM and CP in comparison to GDC.

Based on fish production performance, this study assessed the feasibility of replacing SBM with CSM in practical diets for cage-raised Nile tilapia during the finishing phase. To accomplish this research, four isoproteic (32% CP) and isoenergetic (2500 Kcal/kg of DE) diets were formulated. Control diet (T1) contained 30 % of SBM and 0% of CSM. The other three diets contained: 20% of SBM and 10% of CSM (T2), 10% of SBM and 20% of CSM (T3) and 0% of SBM and 30% of CSM (T4). Lysine and Methionine deficiency was compensated for with synthetic amino acid (L-lysine and DL- methionine) supplementation. Experimental design was completely randomized with four treatments and four repetitions. Data were analyzed with SAS PROC GLM through co-variance analysis, adding initial mean weight as a co-variable, followed by Dunnett test. The system used to calculate the profit part was Partial Budget Analysis in Aquaculture, proposed by Shang (1990). Profit was significantly different at T3 when compared to T1 (control). It was concluded that the addition of 20% of CSM to finishing diets can improve cage-raised Nile tilapia profitability.

In Brazil, the exploration and use of the Hevea brasiliensis Mull Arg. wood at the end of the latex production cycle from 30 to 35 years, is practically unknown. However, one of the most significant problems with its use relates to the high susceptibility of this species wood to the fungus Botryodiplodia theobromae attack, especially during the primary wood processing phase. The present study evaluated the efficacy of four chemicals to control juvenile and adult Hevea brasiliensis wood from the attack of the fungus stainer Botryodiplodia theobromae following the ASTM 4445 (2003) standard. The results showed that the active ingredients separately tested and evaluated in the laboratory; (Quinolinolato Copper - 8 and Carbendazim (T1); Tribromofenol 2-4-6 (T2); Extract-Based Vegetable Tannin (T3); Carbendazim and Prochloraz (T4)) do not totally prevent the contamination of Botryodiplodia theobromae in 5% level of significance

Label is every and any information regarding to a product that is transcribed in its package. For the consumer it is through the nutritional information tables contained in the labels that there is access to data such as quantity and percentage of nutrients contained in foods. Through this knowledge, it is possible to make healthier food choices, minimizing the negative effects related to poor nutrition in the population, especially among children, the most critical rate of obesity incidence. The aim of this study was to evaluate the appropriateness of the labels of some foods consumed by children in relation to the Recommended Daily Intake (RDI) and verify that the general aspects of the labels were in accordance with Brazilian regulations. Five products were selected like snacks, corn snacks, snacks, peanut, peanuts, potato snacks and biscuit recipes. The labels of different brands of each snack were analyzed using the Checklist of Labelling, which is based on RDC No. 259 and RDC No. 360. The nutritional adequacy of nutrients from these foods (carbohydrates, protein, total fat, saturated fat, trans fat, dietary fiber and sodium) was evaluated in relation to that recommended by the RDA for children 4-8 years old. There was small percentage of mistakes in the labels of the analyzed foods, about 12%, being the presence of words that induce the consumers to the misunderstanding the irregularity with larger predominance, present in 25% of the labels. Other items in disagreement were the incomplete specification of the addictive ones alimentary in the list of ingredients and the absence of instructions about the conservation of the foods after opening the packings, both with percentile of occurrence of 18,75%. The high sodium content found in the nutritional information of food shows that should reduce the consumption of these products among children.

As xilanases são enzimas que hidrolisam as ligações 1,4-β-xilosídicas da xilana e que possuem potencial biotecnológico em vários processos industriais, como na clarificação de sucos e vinhos, na fabricação de pães, na produção de biocombustíveis e no tratamento das polpas celulósicas. Além disso, os produtos de hidrólise da xilana, xilooligossacarídeos, podem ser utilizados como ingredientes prebióticos, ou seja, ingredientes nutricionais não digeríveis que estimulam seletivamente a proliferação e a atividade de bactérias benéficas do cólon. O uso de enzimas microbianas nas indústrias se dá devido às suas diversas vantagens sobre os métodos químicos e à facilidade de obtenção do microrganismo. Assim, os objetivos deste trabalho foram: produzir e caracterizar parcialmente a xilanase de Aspergillus sp isolado de pó de café utilizado, purificar parcialmente a enzima produzida e analisar os produtos de hidrólise da xilana. O Aspergillus sp mostrou-se bom produtor de xilanase quando o pó de sabugo de milho foi utilizado como fonte de carbono e a xilanase produzida apresentou melhor atividade específica quando o período de cultivo foi de 168 horas. Os processos de precipitação de proteínas e diálise promoveram o aumento da atividade específica do extrato. A xilanase de Aspergillus sp apresentou pH e temperatura de máxima atividade semelhantes aos de produzidas por Aspergillus niger isolados de outras fontes. A hidrólise da xilana produziu xilose e xilooligossacarídeos. Além da xilanase, o fungo revelou ser produtor de outras proteínas que podem ser estudadas em pesquisas futuras.
