A study was carried out to investigate the performance of anti-corrosion coatings obtained from alkyd paints containing polyaniline and derivatives applied on carbon steel. The polyaniline, derivates were characterized through FTIR Raman spectroscopies thermogravimetric analysis. Cyclic voltammetry studies showed that its gave electroactive properties paints. Accelerated corrosion experiments (salt spray humidity chamber) revealed a significant improvement in which contained polymer compared...
To evaluate in vitro interactions between paromomycin sulphate and the antileishmanial drugs meglumine antimoniate, amphotericin B, miltefosine azithromycin against intracellular Leishmania (Leishmania) infantum chagasi, (Viannia) braziliensis amazonensis amastigotes peritoneal mouse macrophages.First, drug susceptibility was assessed 3, 5 7 day assays, followed by interaction assays with a modified fixed-ratio method. An overall mean sum fractional inhibitory concentration (∑FIC) calculated...
The objective was to evaluate if supplemental LH given at the end of FSH treatment would synchronize time ovulation and increase rate embryo yield in Santa Ines ewes. Twenty superovulatory (SOV) programs were accomplished cross-over design (60d interval). On D0, a CIDR device inserted, replaced with new one 7 days later, when 37.5µg d-cloprostenol administered. D12, we started SOV treatment, administering 256mg pFSH 8 times, 12h apart. D14, removed, 200IU eCG D15, ewes allocated into two...
Polymeric membranes for electrodialysis, fuel cells, and other purposes with specific characteristics have been the focus of innumerable researches. The aim this work was to evaluate sulfonated polyaniline polyurethane, obtained in presence former, regarding its mechanical electrical properties. Polyurethane (PU) prepared from castor oil 4–4-diciclohexilmethane isocyanate (HMDI). Polyaniline synthesized by chemical oxidation, as described literature, chlorosulfonic acid dichloroethane....
Abstract: The objective of this work was to assess the nutritive value four elephant grass (Pennisetum purpureum) genotypes. chemical composition, intake by sheep, and digestibility different genotypes (G1, G2, G3, G4) were evaluated. A dry matter (DM) assay performed with total leftovers feces collected from 20 sheep kept in metabolic cages. G3 had lower DM grams per animal day compared G1 it greater digestibility, crude protein, neutral detergent fiber, acid fiber values. G1, G4 have best...
Abstract In this work, discarded glass bottles (GB) and eggshells (ES) were used to produce foam designed for thermal insulation. The literature on the conductivity of glasses produced with is sparse. This material was as pore‐forming agent at 3% 5% weight fractions obtain a low conductivity. Homogenized powders uniaxially pressed, compacts fired three temperatures (800, 850, 900°C). Raw materials characterized by chemical analysis particle size distribution. their porosity, phases,...
Foi analisada a serie historica de dados referentes frota arrasteiros camarao-rosa do Estado Sao Paulo para o periodo 1968 1989, obtidos pelo Instituto Pesca/SP. Este foi separado em quatro quinquenios (1968-1972; 1973-1977; 1978-1983; 1984-1989) que identificam as diversas fases caracterizaram evolucao da pescaria com base nos trabalhos avaliacao pesqueira. Uma clara mudanca no padrao observada ao longo dos analisados. No primeiro periodo, elevada CPUE das especies-alvo sustentava bons...
This study was aimed to investigate the follicular growth of Morada Nova sheep supplemented with crude glycerin before mating. Eighteen ewes were subjected wave and estrus synchronization three injections D-cloprostenol administered via IM, on days -14, -7 -1 Animals randomized into two groups, control (n = 9), which received an oral drench solution 200 mL saline solution, group supplied glycerol as in (9:1), 1h after morning feeding. Glycerin for 6 days, beginning 7 from mate. Growth...
RESUMO:Objetivou-se avaliar o comportamento ingestivo de ovinos alimentados com dietas contendo diferentes concentrações óleo residual fritura.Foram mantidos em gaiolas metabólicas, 20 animais da raça Santa Inês, machos, peso corporal médio 25 kg, distribuídos um delineamento inteiramente casualizado, cinco fritura (0; 2; 4; 6 e 8%) matéria seca (MS) do concentrado, quatro repetições por tratamento.As atividades comportamentais foram avaliadas período 48 horas ininterruptas.Foram contínuas...
Abstract Rice husk is an abundant waste at the Rio Grande do Sul, Brazil, and it can be used to produce pure silicon dioxide, which main component of bioglass-ceramics. The addition compounds, such as SrO, improve biocompatibility these biomaterials. Therefore, goal this paper was use rice dioxide a cheap precursor obtaining bioglass-ceramics system 50%SiO2-25%Na2O-(25-x)%CaO-x%SrO (mol%) by sol-gel investigate its potential biomaterial. Two samples (BGC blank BGC-5%Sr) were synthesized...
A produção desembarcada do camarão sete-barbas no Brasil mostrou uma redução considerável nos últimos anos quando comparada a anteriormente descrita. Na avaliação risco de extinção, espécie foi categorizada com “Dados Insuficientes - DD”, neste sentido, este trabalho preenche algumas das lacunas conhecimento em tradicional área pesca Estado Santa Catarina. Foram realizadas, entre fevereiro 1993 novembro 1994, 41 amostragens sendo observados 14.873 indivíduos. As fêmeas predominaram na...
Protein nutrition plays a key role in ruminant performance and represents the largest proportion of costs animal feed. The present study evaluated whether roughage portion Santa Inês sheep diets could be supplemented with different ratios tropical kudzu as protein source assessed best inclusion level based on digestibility, intake, nitrogen balance feeding behavior. Twenty rams were during 20-day experimental period, they fed formulated (60%) consisting Elephant grass kudzu, latter at...
O objetivo deste trabalho foi padronizar um método de ultrassonografia para exames do parênquima testicular em andrológicos carneiros (n=6). Foi realizada biometria testicular, espermiograma e exame ultrassonográfico realizando imagens aferido o percentual ecogenicidade pela escala cinza no próprio aparelho, correlacionando com dados da espermiograma. Verificaram-se correlações positivas entre a concentração espermática (p=0,0192 r2= 0,4373) motilidade massal (p=0,0358 0,37), demonstrando...
