26. Armazenamento do leite de cabra cru em diferentes temperaturas por diferentes períodos e influência nas qualidades microbiológica, físico-química e sensorial do produto pasteurizado / Raw goat milk storage at different temperatures for different periods and influence in microbiological, pshysical-chemical and sensorial qualities in pasteurized product
Different periods of storage (0, 3 and 6 days) and temperatures (4 and 10ºC) effects of raw goat milk on pasteurized product were evaluated. Microbiological and physical-chemical alterations in raw and pasteurized goat milk stored for up six days were evaluated. Pasteurization (65ºC/30 minutes) was used and samples were kept at 10ºC for 0, 3 and 6 days. C

27. PRECONDITIONING OF ORGAN DONORS WITH LOW LEVELS OF CARBON MONOXIDE REDUCES GRAFT IMMUNOGENICITY AND IMPROVES LONGTERM ALLOGRAFT FUNCTION
Background: Chronic rejection remains the major obstacle for successful transplantation, and to date there is no effective treatment. Events occurring prior to organ transplantation such as brain death, harvesting procedure, and ischemia-reperfusion injury lead to unspecific inflammatory damages danger signals - that increase graft immunogenicity and reduce

28. Formation and properties of nylon 6 nanocomposites
Sodium montmorillonite clay consists of platelets, one nanometer thick with large lateral dimensions, which can be used to achieve efficient reinforcement of polymer matrices. Formation of these nanocomposites requires modifying the clay with an appropriate organic surface treatment and optimized processing. Some of these techniques and the resulting propert

29. Windrowing and prismatic baling of sugarcane trash: some operational acting parameters and energy efficiency. / Enleiramento e enfardamento prismático de palhiço de cana-de-açúcar: alguns parâmetros de desempenho operacional e eficiências energética.
This study was carried out aiming to evaluate some parameters of operational acting of windrowing and prismatic baling operations sugarcane trash picked mechanically without a previous burning and energy efficiency. The field tests were performed in a sugar cane trash field in Piracicaba, State of São Paulo, Brazil. The geographic location of the area is: l

30. InteraÃÃo entre fatores climÃticos e um recinto localizado na cidade de recife: estudo teÃrico-experimental
Ambient temperatures lying between medium and high values, combined with small thermal amplitude, high values of relative humidity and solar radiation make the city of Recife a region that can be considered as having scarce possibilities for the use of passive or low energy consumption methods for providing thermal comfort conditions in local residences.

31. Forjamento da liga AA 2011 no estado semi-solido : estudo do processo e do produto
The work deals with the ana1ysis of the semi-solid technology applied to the thixoforming of AA 20011 aluminium alloy. Initially it was studied the influence of temperature in the quality of semi-solid raw material suitable for thixoforming (spheroidal morphology in the solid phase) when producing such material by partial melting of super-refined as-cast str

32. Obtenção e caracterização de filmes finos ferromagneticos das fases FE17TR21 TR=Nd, Pr e Sm
Films of the Fe17R2Nx phases, R= rare-earthsf are interesting because of the good magnetic and properties these materiais have in bulk form, mainly for R from = Sm, that show axial magnetic anisotropy .In film form these good magnetic properties are maintained, and films can show perpendicular anisotropy high coercivities. For Pr and Nd the bulk material was

33. Fios supercondutores de Cu-Nb3Sn preparados pelo metodo sinterização na fase liquida do cobre, com o uso de Nb-H
We prepared sintered samples of Cu-30wt%Nb using the new method "Sinterization in a Copper Liquid Phase" introduced in 1981 by O.F. de Lima. This method was improved here with the substitution of Nb powder, used in the original method, by Nb-H powder. The advantages are: 1) the oxygen content adsorbed in Nb-H powders is less than that of Nb powders. 2) The h

34. Phenotypical Temperature Adaptation of Protein Synthesis in Wheat Seedlings 1: QUALITATIVE ASPECTS. INVOLVEMENT OF AMINOACID:tRNA-LIGASES
Phenotypical temperature adaptation of protein synthesis in wheat (Triticum aestivum L.) seedlings is not affected by darkness (etiolation), by partial inhibition of protein biosynthesis (10−3m fluorophenylalanine), or by changing the amino acid precursor and the radioisotope ([3H]valine instead of [14C]leucine). The temperature coefficient (μ), as well a

35. Comparison of effects of nicked and unnicked Escherichia coli heat-labile enterotoxin on Chinese hamster ovary cells.
The effect on nicking (proteolytic cleavage) of heat-labile enterotoxin (LT) on its activities on Chinese hamster ovary (CHO) cells was examined. LT nicked with trypsin induced morphological change (elongation) of CHO cells from round to spindle-shaped cells faster than did unnicked LT. The times for elongation of 50% of the CHO cells with nicked and unnicke

36. Molecular cloning and characterization of the 78-kilodalton glucose-regulated protein of Trypanosoma cruzi.
The protozoan Trypanosoma cruzi is the etiologic agent of Chagas' disease, an illness responsible for morbidity and death among millions of Latin Americans. Mice also develop this disease when infected with T. cruzi and are a useful model organism for the study of parasite-specific immune responses. To identify immunogenic T. cruzi antigens, serum from an in
