Objective: This study was to evaluate the effects of individual or combinational use of phytase, protease, and xylanase on total tract digestibility of corn, soybean meal, and distillers dried grains with soluble (DDGS) fed to pigs. Methods: Each experiment had four 4×4 Latin squares using 16 barrows. Each period had 5-d adaptation and 3-d collection. All experiments had: CON (no enzyme); Phy (CON+phytase); Xyl (CON+xylanase); Pro (CON+protease); Phy+Xyl; Phy+Pro, Xyl+Pro, Phy+Xyl+Pro. Each Latin square had 'CON, Phy, Xyl, and Phy+Xyl'; 'CON, Phy, Pro, and Phy+Pro'; 'CON, Pro, Xyl, and Xyl+Pro'; and 'Phy+Xyl, Phy+Pro, Xyl+Pro, Phy+Xyl+Pro'. Results: The digestible energy (DE), metabolizable energy (ME), and nitrogen retention (NR) of corn were not affected by enzymes but the apparent total tract digestibility (ATTD) of phosphorus (P) was improved (p<0.01) by Phy. The DE and ATTD dry matter (DM) in soybean meal were increased (p<0.05) by Phy+Pro and the ATTD P was improved (p<0.01) by Phy, Phy+Pro, and Phy+Xyl. The DE, ME, and ATTD DM in DDGS were improved (p<0.05) by Phy+Xyl and the ATTD P was improved (p<0.01) by Phy, Phy+Pro, and Phy+Xyl. Conclusion: Phytase individually or in combination with xylanase and protease improved the Ca and P digestibility of corn, soybean meal, and DDGS, from the hydrolysis of phytic acid. The supplementation of protease was more effective when combined with phytase and xylanase in the soybean meal and DDGS possibly due to a higher protein content in these feedstuffs. Xylanase was more effective in DDGS diets due to the elevated levels of non-starch polysaccharides in these feedstuffs. However, when xylanase was combined with phytase, it demonstrated a higher efficacy improving the nutrient digestibility of pigs. Overall, combinational uses of feed enzymes can be more efficient for nutrient utilization in soybean meal and DDGS than single enzymes.

Determination of kinetic parameters for the sisal residue pyrolysis through thermal analysis

Daniel Bemmuyal Passos Santos,Marcos Fábio de Jesus,José Mário Ferreira Júnior,Carlos Augusto de Moraes Pires 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.109 No.-

Determining the kinetics of biomass degradation by thermogravimetry is complex due to the existence ofnumerous parallel and consecutive reactions. The individual use of models available in the literature haslimitations regarding the applicability of the data due to high adjustment errors or lack of process information. Thus, a new procedure was proposed to determine the degradation kinetics of sisal residue, atheating rates of 20–80 C/min and inert atmosphere. First, the reaction order was determined by thefit model for each heating rate, resulting in approximate values. Then, the activation energy and thepre-exponential factor were determined by free models (Flynn-Wall-Ozawa, Kissinger-Akahira-Sunose,and Friedman). These models were validated from the experimental data of conversion and temperature,together with the calculated kinetic parameters. Friedman’s model was the best fit. Finally, the errorsobtained are compatible with those in the literature, indicating that this procedure can be used in kineticsinvolving biomass pyrolysis.

( Gildeneide Dos Passos Freire ) 한국포르투갈-브라질학회 2007 포르투갈-브라질 연구 Vol.4 No.1

This article is the result of Positivist and Technical scientific comment, factual, realized in " I Conferência de Política para as Mulheres"occurred in Brasilia - DF - Brazilof 15 to 17 july of 2004. At times the international Reports pointed to Brazil in line setback in matters involving public policies for women. The working method used was the bibliographical search, a priori, and the subsequent observation. Data obtained took account a search for basic scientific research funded by Ministério da Educação and by Vice-Reitoria de Pós-Graduação e Pesquisa da Universidade Católica de Goiás (UCG) that performed together with my guiding, called "Memória da Secretaria da Condição Feminina: uma efêmera história de mulheres goianas no poder de 1987-1991". The assumption of organized women, politically, could change the Legislative, Executive and Judicial system of Brazilwas proven. Data can be any kind of verification. While work of scientific research it is characterized for the most part by the description. The model obtained can be applied in other democratic societies that have similar characteristics to that of Brazil. The results will depend on the socio-cultural behaviour and the position occupied by women in society investigated. The independent variable proved the hypothesis affirmative, above. The dependent variable was the results obtained from the observation of the political behavior of women organized and the political results achieved in the three spheres of power of Municipal governments, State and Distrito Federal, after "I CNPM-2004". We can say that women in Brazilundertaken many joints policies for the minimum of Human Rights were guaranteed to them and their families. Advances were in the areas of health, education, environment, labour and income, non-discrimination by race, color, sex, gender, language, ethnicity, political and religious freedoms, among others.

Questões sobre agricultura no âmbito da Organização Mundial de Comércio (OMC)

( Rogério Duarte Fernandes Dos Passos ) 한국포르투갈-브라질학회 2007 포르투갈-브라질 연구 Vol.4 No.2

This text, objective, in a first time, describe the institutional environment existing in international society after World War II desired the creation of the International Organization of Trade. Do not implementing this, describes itself as the emergence of the GATT Agreement for the international relations of trade, culminating, with the Marrakesh Agreement of 1995, the creation of the World Trade Organization as a specialized agency of the United Nations system. Then, the text describes the rounds of negotiations held under the World Trade Organization, considering the latter - the Doha Round ― which started in 2001 and active until the present day, the formation of blocs emerging-country negotiators - as in the G-20 ― and proposed agreements involving the most diverse agricultural sector, as what became known as the “Triangle of Mandelson”, in allusion to that by Peter Mandelson, European Commissioner trade. Finally, reflecting the ambitions Brazilian - and opposition to them - leading to a possible project overall production of biofuels to replace the matrix from fossil and considering the last WTO panel that judged in favor of Brazil the subsidies North Americans for its production of cotton as incompatible with the policy of world trade, is an overview of the challenges that are imposed on Brazilian agribusiness.

Purpose: The purpose of this study was to use cone-beam computed tomography (CBCT) images to determine the prevalence of calcifications in the temporomandibular joint (TMJ) and to evaluate any associations between the presence of such calcifications and degenerative bone alterations of the TMJ, sex, or age. Materials and Methods: In this retrospective study, 1,058 CBCT exams were analyzed, and data regarding the presence and quantity of calcifications, the affected side, any degenerative alterations of the condyle, sex, and age were collected. To evaluate associations between the presence of calcifications and sex or age, the Fisher exact test or the Spearman correlation coefficient, respectively, was used. To assess the association between the presence of calcifications and joint bone alterations, the chi-square and Fisher exact tests were used. The significance level adopted was 5% (P<0.05). Results: Twenty-eight patients (2.7%) presented with TMJ calcifications, including 23 women (82.1%) and 5 men (17.9%). Significant correlations were found between the presence of calcifications and age (P<0.05) and between the presence of calcifications and the presence of condylar alterations (P<0.05), with 73.2% of patients with bone alterations having TMJ calcifications. Conclusion: It may be concluded that, although rare (with a prevalence of only 2.7%), intra-articular calcifications are associated with both degenerative bone alterations and age

de Melo, Mary Anne Sampaio,Passos, Vanara Florencio,Lima, Juliana Paiva Marques,Santiago, Sergio Lima,Rodrigues, Lidiany Karla Azevedo The Korean Academy of Conservative Dentistry 2016 Restorative Dentistry & Endodontics Vol.41 No.4

Objectives: The aim of this investigation was to give insights into the impact of carbohydrate-electrolyte drinks on the likely capacity of enamel surface dissolution and the influence of human saliva exposure as a biological protective factor. Materials and Methods: The pH, titratable acidity (TA) to pH 7.0, and buffer capacity (${\beta}$) of common beverages ingested by patients under physical activity were analyzed. Then, we randomly distributed 50 specimens of human enamel into 5 groups. Processed and natural coconut water served as controls for testing three carbohydrate-electrolyte drinks. In all specimens, we measured surface microhardness (Knoop hardness numbers) and enamel loss (profilometry, ${\mu}m$) for baseline and after simulated intake cycling exposure model. We also prepared areas of specimens to be exposed to human saliva overnight prior to the simulated intake cycling exposure. The cycles were performed by alternated immersions in beverages and artificial saliva. ANOVA two-way and Tukey HDS tests were used. Results: The range of pH, TA, and ${\beta}$ were 2.85 - 4.81, 8.33 - 46.66 mM/L and 3.48 - $10.25mM/L{\times}pH$, respectively. The highest capacity of enamel surface dissolution was found for commercially available sports drinks for all variables. Single time human saliva exposure failed to significantly promote protective effect for the acidic attack of beverages. Conclusions: In this study, carbohydrate-electrolyte drinks usually consumed during endurance training may have a greater capacity of dissolution of enamel surface depending on their physicochemical proprieties associated with pH and titratable acidity.
