Abstract: Objetivou-se avaliar os efeitos da aduba o química e organica sobre a composi o químico-bromatológica do capim elefante, além de estimar a energia líquida do volumoso e os nutrientes digestíveis totais desta forrageira. Foram formadas duas áreas de capineiras e utilizados dois sistemas de aduba o. Utilizou-se delineamento em blocos (seis períodos), casualizados completos e três repeti es por volumoso (aduba o química e aduba o organica) por bloco. Os dados de proteína bruta, fibra em detergente neutro, cinzas, cálcio, magnésio, potássio e fósforo foram avaliados pelo teste F, a 5% de probabilidade. Com base na fibra em detergente neutro, estimou-se a energia líquida do volumoso e os nutrientes digestíveis totais do capim-elefante nos dois sistemas de aduba o. Com base nos resultados, observa-se que o capim-elefante submetido à aduba o organica apresenta maiores valores em sua composi o químico-bromatológica. Foram observados nesta forragem submetida à aduba o organica, maiores teores de proteína bruta (17,26%), cinzas (26%) e fósforo (36,88%) e menores teores de fibra em detergente neutro (3,96%) em rela o ao capim-elefante submetido à aduba o química. A aplica o de esterco de curral na capineira de capim-elefante melhorou o teor de matéria organica no solo, o que propiciou melhoria na composi o químico-bromatológica, além de proporcionar maior flexibiliza o na frequência de utiliza o da capineira em rela o à adubada químicamente. The objectives of this work were to study the effect of chemical and organic fertilization on the forage dry matter chemical composition characteristics of elephant grass and to estimate the total net energy of forage and the total digestible nutrients. Two elephant grass stocking piles were formed and two fertilization systems were used. Soil and plant evaluations (chemical and physical analysis) were performed at field. Was carried out in a completely block (six periods) randomized design and three replicates per forage (chemical and organic fertilization) per block. Data of crude protein, neutral detergent fiber, and ashes, calcium, phosphorus, magnesium and potassium were evaluated by F test, at 5% of probability. Based on the total digestible nutrients contents, the total net energy and total digestible nutrients of the elephant grass from the two fertilization systems were estimated. The elephant grass submitted to fertilization organic showed higher chemical composition values. In this forage, higher contents of crude protein (17.26%), ashes (26%) and phosphorus (36.88%) and smaller of neutral detergent

Abstract: mesquite [prosopis juliflora (sw) d.c.], a perennial tropical plant commonly found in brazilian semi-arid region, is a viable raw material for fermentative processes because of its low cost and production of pods with high content of hydrolysable sugars which generate many compounds, including ethanol. this study aimed to evaluate the use of mesquite pods as substrate for ethanol production by z. mobilis ufpeda205 in a submerged fermentation. the fermentation was assessed for rate of substrate yield to ethanol, rate of ethanol production and efficiency of fermentation. the very close theoretical (170 g l-1) and experimental (165 g l-1) maximum ethanol yields were achieved at 36 h of fermentation. the highest counts of z. mobilis ufepeda-205 (both close to 6 log cfu ml-1) were also noted at 36 h. highest rates of substrate yield to ethanol (0.44 g ethanol g glucose-1), of ethanol production (4.69 g l-1 h-1) and of efficiency of fermentation (86.81%) were found after 30 h. these findings suggest mesquite pods as an interesting substrate for ethanol production using submerged fermentation by z. mobilis.

Abstract: OBJETIVO: o estudo busca determinar a existência de associa o entre a eleva o da press o arterial e os níveis plasmáticos dos peptídeos natriuréticos ANP e BNP, na gesta o complicada pela pré-eclampsia. MéTODOS: em estudo transversal caso-controle, pareado por idade gestacional, 25 grávidas normotensas e 61 portadoras de pré-eclampsia foram avaliadas quanto ao nível da press o arterial e às concentra es plasmáticas dos peptídeos natriuréticos ANP e BNP. Exames clínico e laboratoriais foram realizados para o diagnóstico de pré-eclampsia, sendo a press o arterial medida de forma n o invasiva. As dosagens hormonais foram obtidas por radioimunoensaio, após extra o em colunas Sep-pak C18. Os valores médios das concentra es plasmáticas do ANP e BNP foram comparados entre grupos com press o arterial progressivamente maiores. A correla o entre os valores da press o arterial e os níveis plasmáticos do ANP e BNP no sangue materno foi também investigada pela de análise de regress o no grupo completo de gestantes e em grupos específicos excluindo-se a hipertens o anterior à gesta o e, em seguida, excluindo-se aquelas sem hipertens o prévia. RESULTADOS: os valores plasmáticos de ANP foram 41.5±7.3, 78.4±13.1 e 89.2±13.4 pg/mL (p<0,00001) e os de BNP plasmático foram 79.5±15.8, 176.7±42.2 e 208.3±63.5 pg/mL (p=0,005), respectivamente, para os grupos de press o arterial média =107 mmHg, 107-139 mmHg e =140 mmHg. Verificou-se correla o positiva entre as concentra es plasmáticas do ANP e os níveis pressóricos na pré-eclampsia, independente da existência de estado hipertensivo prévio à gesta o (p<0,0001 para pré-eclampsia e p<0,01 para pré-eclampsia sobreposta à hipertens o arterial cr nica), ao passo que as dosagens de BNP n o se mostraram associadas à press o arterial no grupo com hipertens o arterial prévia à gesta o (p=0,004 para pré-eclampsia e p=0,18 para pré-eclampsia sobreposta à hipertens o arterial cr nica). CONCLUS O: o agravamento da hipertens o na pré-eclampsia correlacionou-se com as concentra es séricas do ANP e BNP, embora os valores do BNP possam ser influenciados pela existência de estado hipertensivo prévio.

Abstract: The reliability of the results generated in analytical laboratory either for the development of new methods or for the appropriate use of methodologies already regulated, is essential to ensure that consumers are receiving a nutritionally adequate and safe food. In this context, traceability has been one of the main requirements required in the analysis, once this allows comparability between results of measurements carried out in different situations, usingvalues of metrological references, clearly defined, within internationally accepted criteria. The objective of this research was to assess the activities developed in a laboratory for research and analysis of food, about the accordance of item 4, which is established requirements of Direction, and the item 5, technical requirements of ISO/IEC 17025:2005, to guide correction of non conformities and internal organization. Initially there was a check list for verification of compliance for the activities developed in the laboratory. When the non-conformities were found, the staff was trained and was applied the 5S System. In applying the first check list in accordance with the item 4, the laboratory was classified in Group 3 of the Standard, with 57.14% of non-conformities, after training and implementation of corrective measures. In a new application of check list, the laboratory was classified in Group 2, and was occurred reduction of 37.5% of non-conformities. As to item 5, the laboratory was classified in Group 2, with 44.44% of non-conformities. After the training and corrective measures, there was reduction of 54% of non-conformities. It can be concluded that for elimination of nonconformance is required to train staff and implement tools such as 5S System and especially encourage the involvement of employees
