Arraste via fecal de nutrientes da ingest o produzido por baga o de mandioca hidrolisado
Raupp Dorivaldo da Silva,Marques Silvia Helena de Paula,Rosa Danielle Amorim,Caldi Carla Marielle
Scientia Agricola , 2002,
Abstract: A ingest o de fibras alimentares pode resultar em arraste de outros nutrientes para as fezes. Baga o de mandioca produzido por polvilheira foi submetido à hidrólise enzimática para obten o de um produto mais concentrado em fibra alimentar insolúvel denominado de baga o de mandioca hidrolisado (BMH). O BMH foi avaliado em ensaios biológicos com ratos Wistar quanto a sua habilidade de arrastar os nutrientes da ingest o para as fezes, tendo como padr o de fibra o farelo de trigo (FT). Acréscimo à dieta base, substituindo igual quantidade de amido, de dose de 5%, 15% ou 25% de BMH promoveu arraste significativo de minerais (globalidade) ou proteína; dose de 15% ou 25% promoveu arraste significativo de lipídeo; e, dose de 25% promoveu arraste significativo de carboidrato digestível. Dose de 25% de FT produziu arraste significativo de minerais (globalidade), proteína ou carboidrato digestível, mas, o lipídeo n o foi arrastado. BMH produziu efeito mais pronunciado que FT em arrastar minerais (globalidade) ou proteína para a dose de 5% ou 15%; no entanto, para a dose alta, de 25%, as fontes produziram efeitos semelhantes em arrastar a proteína, mas o FT promoveu maior arraste de minerais (globalidade). N o houve diferen a entre fontes, BMH e FT, em arrastar lipídeo ou carboidrato digestível para as fezes. Na dose alta (25%) o BMH promoveu efeitos, no máximo, semelhantes ao FT, em arrastar para as fezes os nutrientes da ingest o; assim, é recomendado como fonte alternativa de fibra alimentar insolúvel para a formula o de alimentos funcionais-digestivos.

Abstract: dietary fiber can drag nutrients in faeces. cassava waste from starch industry can be hydrolyzed by an enzymatic process and give origin to a food with high content of insoluble dietary fibers, named partially hydrolyzed cassava waste (hcw). hcw or standard wheat bran (wb) were fed to model growing rats in order to assess their dragging skill of nutrients from the intake of faeces. addition of 5%, 15% or 25% hcw, in replacement of starch, promoted a significant dragging proportion for the overall minerals or proteins; addition of 15% or 25% hcw dragged a significant proportion of lipids and the addition of 25% hcw dragged a significant proportion of digestible carbohydrates. adding 25% wb caused significant dragging of total minerals, protein and digestible carbohydrates, lipids were, however, not dragged with wb treatment. hcw promoted a more pronounced effect as compared to wb in regard to the dragging process of total minerals or proteins for 5% or 15% additions. nervertheless, for high rates, such as 25% additions, both fibrous sources produced similar effects on the dragging of protein, but wb promoted the greatest dragging process of total minerals. no differences between both fiber sources were observed as to their abilities of dragging lipids or digestible carbohydrates into faeces. with high rates (25%) hcw promoted effects similar to wb, allowing to conclude that hcw might be used as an important alternative source of insoluble dietary fiber for the formulation of digestive-functional feeds.
Reality of Complex Affine Toda Solitons
Z. Zhu,D. G. Caldi
Physics , 1994, DOI: 10.1063/1.531194
Abstract: There are infinitely many topological solitons in any given complex affine Toda theories and most of them have complex energy density. When we require the energy density of the solitons to be real, we find that the reality condition is related to a simple ``pairing condition.'' Unfortunately, rather few soliton solutions in these theories survive the reality constraint, especially if one also demands positivity. The resulting implications for the physical applicability of these theories are briefly discussed.
Multi--Soliton Solutions of Affine Toda Models
Z. Zhu,D. G. Caldi
Physics , 1993, DOI: 10.1016/0550-3213(94)00326-A
Abstract: Hirota's method is used to construct multi--soliton and plane--wave solutions for affine Toda field theories with imaginary coupling.
Cosmological Neutrino Condensates
D. G. Caldi,Alan Chodos
Physics , 1999,
Abstract: We investigate the possibility that neutrinos form superfluid-type condensates in background cosmological densities. Such condensates could give rise to small neutrino masses and splittings, as well as an important contribution, perhaps, to the cosmological constant. We discuss various channels in the context of the standard model. Many of these do not support a condensate, but some mixed-flavor channels do. We also suggest a new interaction, acting only among neutrinos, that could induce a neutrino Majorana mass of order 1 eV.
Digestive and functional properties of a partially hydrolyzed cassava solid waste with high insoluble fiber concentration

Scientia Agricola , 2004, DOI: 10.1590/S0103-90162004000300008
Abstract: starch factories generate large amounts of cassava solid waste. a small amount is utilized for animal feed but most of it is discharged with deleterious effects to the envirounment. a edible food with a high content of insoluble dietary fiber (60.9%), named "partially hidrolyzed cassava waste" (phcw), was prepared from industrial cassava solid waste by an enzymatic process. phcw or wheat bran (wb) were fed to model rats and both promoted digestive function effects, but phcw produced the greatest effect. the insoluble fiber constituent from phcw (and not the soluble fiber), promoted the greatest fecal bulking, fecal weight and defecation frequency in rats, as compared to wb. such results indicate that the partially hydrolyzed cassava waste presents digestive function properties which allow it to be used as an adequate source of insoluble dietary fiber in the formulation of functional food for human nutrition.

As estimativas dos coeficientes de herdabilidade foram 0,17; 0,41; 0,03 e 0,08 para PL, IPP, IDP e DL, respectivamente. A correla o genética entre a PL e a DL foi alta e igual a 0,89. Já a correla o genética entre a PL e o IDP foi de apenas -0,25. N o ficou constatada associa o genética entre a idade ao primeiro parto e a produ o de leite na primeira lacta o. A produ o de leite pode ser utilizada como característica auxiliar na sele o visando o melhoramento da dura o da lacta o e do intervalo de partos em bubalinas.
Modelos n o lineares utilizados para descrever o crescimento de bovinos da ra a Nelore no estado da Bahia: 1. Efeito ambiental
Carlos Henrique Mendes Malhado,Alcides Amorim Ramos,Paulo Luiz Souza Carneito,Danielle MAria Machado Ribeiro Azevedo
Revista Brasileira de Saúde e Produ??o Animal , 2009,
Abstract: O objetivo, neste estudo, foi avaliar modelos n o lineares para descrever o crescimento de bovinos da ra a Nelore no estado da Bahia. Utilizaram-se dados de, no mínimo, oito pesagens obtidas em intervalos de aproximadamente 90 dias, do nascimento aos 2 anos de idade, de 6.855 bovinos, provenientes da Associa o Brasileira dos Criadores de Zebu (ABCZ). Os modelos n o lineares utilizados foram: Brody, Von Bertalanffy, Richards, Logístico e Gompertz. Após a identifica o do modelo que melhor descreve o crescimento, calculou-se a taxa de crescimento absoluto e analisou-se a influência dos fatores ambientais sobre o peso assintótico (A) e taxa de maturidade (k). Os modelos Logístico e Gompertz apresentaram os melhores ajustes, com ligeira superioridade do primeiro. Todos os efeitos ambientais do modelo (sistema de cria o, sexo, fazenda, mês e ano de nascimento) influenciaram significativamente os parametros A e k. As correla es de Pearson entre A e k foram negativas e iguais a -0,62 e -0,61 para machos e fêmeas, respectivamente, sugerindo que animais com maior peso adulto provavelmente ter o menor velocidade de crescimento. As fêmeas foram mais precoces e de menor peso à maturidade em rela o aos machos, contudo, esses possuem maior velocidade de crescimento.
