37. Grau de moagem do milho, inclusão de subprodutos agroindustriais e aditivo microbiológico em rações para vacas leiteiras. / Corn grain grinding, agriculture industrial byproducts and yeast culture in dairy cow rations.
Three experiments were conducted to assess the effects of corn grain grinding, byproducts and yeast culture supplementation in dairy cow rations containing corn silage as forage. Experiment 1: Thirty six lactating Holstein cows (330 days in milk - DIM) were used to study the supplementation of yeast culture (Levucell SC20 Lallemand Animal Nutrition) in da

38. Produção de proteinas recombinantes utilizando Escherichia coli em cultivos em alta densidade celular
This thesis studied submerged high cell-density cultures (HCDC) of recombinant Escherichia coli identifying important kinetic parameters on growth and production phases. Several strategies to obtain HCDC were studied aiming to develop a robust fermentation process that allowed: High cell dry weight per liter; to determine the nutritional conditions to expres

39. Uma contribuição para avaliação do passivo contingencial em empresas de prestação de serviços de alimentação : um estudo de caso
The cost on the payroll is a considerable part in the composition of labour costs, mainly those related to intensive labour. An important part of this cost, the fine on the FGTS fund, laid down on the article 22 of the Law Decree 53820 of December 20th 1966 and its last updating through the complementary Law 110/01 of June 29th 2001, whose validity goes from

40. Use of tower reactors for continuous ethanol production
The purpose of this work was to develop a continuous fermentation system operating with a tower reactor using some flocculent yeast strains isolated from an industrial process. The strain was an used in the trial of the proposed system, composed of two serial glass tower reactor. The effects of the following variables were studied on the yield and productivi

41. Mercado de rochas calcarias e fosfaticas para nutrição animal
Industrial mineraIs markets have been showing continuous progress both on the national and intemational levels. The segrnent of animal nutrition has been improved with the implementation of new handling technologies which increase the consumption of mineral elements due to the vital functions in the feeding diet of animaIs. Among the mineral feedstuffs used

42. Fluidized bed reactor for polyethylene production. The influence of polyethylene prepolymerization
This work addresses the influence of the prepolymerization of the catalyst particle on the fluidized bed reactor for polyethylene production. The influence of prepolymerization on the temperature and concentration gradients throughout the reactor was studied. The results obtained through simulations confirm industrial observations of the advantages of prepol

43. Modelagem matematica, controle e otimização do processo de incineração em formos rotativos com pos-combustor
The development of a suitable mathematical model, in steady state and dynamic conditions , to carry out optimization and control of the large scale incineration process, stimulated the approach proposed in this work. The development of the mass and energy balances, as well as all the flows of heat, conductive, convective and radiative, were idealized to have

44. Locomotivas de C.A : uma analise harmonica da corrente
AC thyristor controlled electric traction became very usual around the world. Thyristors provide good control performance but they always cause problems to the traction electric system. Overvoltages may arise in the contact line feeding the locomotive and also harmonics generated in the thyristors may affected the grid to which the whole system is connected.

45. Sequential megafaunal collapse in the North Pacific Ocean: An ongoing legacy of industrial whaling?
Populations of seals, sea lions, and sea otters have sequentially collapsed over large areas of the northern North Pacific Ocean and southern Bering Sea during the last several decades. A bottom-up nutritional limitation mechanism induced by physical oceanographic change or competition with fisheries was long thought to be largely responsible for these decli
