13. Compostagem e solarizaÃÃo para higienizaÃÃo de lodo de esgoto e uso no cultivo de CÃsia Amarela (Senna Siamea Lam)
The sewage sludge is the main waste produced in Wastewater Treatment Plants (WTPs). Itâs final destination called the attention of several govenmental agencies and research intitutions. Proper disposition of sewage sludge is fundamental in order to avoid potential environmental damages. The beneficial use of sludge in agriculture, has well established pract

14. ExercÃcio agudo realizado a baixo ou acima do limiar anaerÃbio induz diferentes comportamentos de ansiedade em ratos wistar
Few studies have investigated the acute/chronic effects of physical exercises on behaviors related to anxiety in animal models and the results are quite contradictory. Those conflicts seem to result from the methodological diversity among the studies, for example, the configuration of the physical exercise program. Materials and methods. Male Wistar rats wer

15. On the formation of solid solution in fat acids binary compounds by X-ray diffraction / Investigação da formação de solução solida de misturas binarias de acidos graxos atraves de difração de raios-X
The X-ray diffraction potential in the analysis of polyerystalline materiaIs enhances when it is associated with the Rietveld method for refinement of crystalline structures, since one can obtain simultaneously: the sample structural parameters, the quantitative phase analysis, the preferred orientation determination, crystallite size and sample micro strain

16. Construção e estudo das condições de operação de uma unidade de pirólise para pneumáticos inservíveis
Today the used tire is considered a residue with quite inadequate final disposition as in embankments. It can cause many environmental and human health problems because it can absorb gases and to burst. When it is burned into nature it forms toxicant substances as sulfur dioxide and powder material. An alternative use of the used is as energy source in indus

17. Estudos físico-químicos do efluente produzido por fossa séptica biodigestora e o impacto do seu uso no solo
The generation of effluent from the sewage treatment is daily increasing then its final disposition represents a mandatory question to be answered. An alternative is its agricultural utilization such as organic fertilizer as a partial substitute of mineral fertilizer. This practice, beyond inherent benefits due to nutrients recycling promotes agricultural wa

18. Study of the effect of alkaline "stress" in production xanthan gum / Estudo do efeito do "stress" alcalino na produção de goma xantana.
The present study had as objective to make a selection of strains of X. campestris for the production of xanthan gum and to verify the effect of the process of alkaline "stress" at different conditions of production of this biopolymer, through the evaluation of the gum production and of the apparent viscosity, which is a factor of high relevance, in order to

19. Estudo de complexos de ferro-cyclam com ligantes carboxilados e polinitrilados / Study of complexes of iron-cyclam with carboxylate ligants and polinitrilate
The main objective of this work is to contribute with the chemistry of the system Fe-Cyclam through the synthesis and characterization of complexes with carboxylate ligants, acetate and oxalate, and polinitrilate ligands, 7,7,8,8-tetracyanoquinodimethane (TCNQ) and tetracyanoethylene (TCNE). The infrared spectra of the cis-[Fe(cyclam)ox]PF6 complex allowed t

20. A new model for the population pharmacokinetics of didanosine in healthy subjects
Didanosine (ddI) is a component of highly active antiretroviral therapy drug combinations, used especially in resource-limited settings and in zidovudine-resistant patients. The population pharmacokinetics of ddI was evaluated in 48 healthy volunteers enrolled in two bioequivalence studies. These data, along with a set of co-variates, were the subject of a n

21. TRATAMENTOS PRÉ-GERMINATIVOS VISANDO MINIMIZAR A DORMÊNCIA EM SEMENTES DE TUCUMÃ (Astrocaryum aculeatum G. MEY.)
This study evaluated the effect of water content and germination pretreatments on Astrocaryum aculeatum and identified possible causes of dormancy. A supplementary study was made in the anatomy and histochemistry of the seed integument. The emergence of plants was favored by soaking independent of temperature and period, but the lower mean time was in a 40C

23. High baseline serum total and LDL cholesterol levels are associated with MDR1 haplotypes in Brazilian hypercholesterolemic individuals of European descent
The MDR1 gene encodes the P-glycoprotein, an efflux transporter with broad substrate specificity. P-glycoprotein has raised great interest in pharmacogenetics because it transports a variety of structurally divergent drugs, including lipid-lowering drugs. The synonymous single-nucleotide polymorphism C3435T and the nonsynonymous single-nucleotide polymorphis

24. Age effects on the pharmacokinetics of tityustoxin from Tityus serrulatus scorpion venom in rats
The pharmacokinetics of scorpion venom and its toxins has been investigated in experimental models using adult animals, although, severe scorpion accidents are associated more frequently with children. We compared the effect of age on the pharmacokinetics of tityustoxin, one of the most active principles of Tityus serrulatus venom, in young male/female rats
