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.
L’essai littéraire, devant le temps
Marielle Macé
Cahiers de Narratologie , 2008, DOI: 10.4000/narratologie.499
Abstract: Le style de vérité accessible à l’essai est perceptible dans son mode de circulation, les souvenirs que l’on en garde, la fa on dont on le résume, bref, l’usage que l’on en fait. Ce mémorable de l’essai tient à une pratique généralisée de la citation ; les essayistes partent de formes citables , comme d’autant de pensées héritées et de savoirs doxaux ou paradoxaux qu’ils exploitent, développent ou fragilisent ; et ils en produisent à leur tour, offrant non pas des modèles applicables mais des cas remobilisables, des pensées désormais disponibles. Cette disponibilité identifie une pratique intellectuelle, les objets qu’elle fait na tre (cette forme sensible que prennent dans un essai les opérations de l’esprit), un rythme propre à toute individualité pensante, bref une fa on qu’a la prose d’idées de se situer devant le temps. Elle explique aussi la colère suscitée dans le monde du savoir contemporain par un genre profondément temporel, c’est-à-dire rythmé, situé, mais aussi précaire et soup onnable à cet égard d’anachronisme. Lo stile di verità accessibile al saggio è percettibile nel modo in cui il testo circola, nei ricordi che ne abbiamo, nella maniera in cui ne facciamo riassunto, cioè nell’uso che possiamo averne. Questo aspetto “memorabile” del saggio è legato ad una prattica generalizzata della citazione. I saggisti partono di forme “citabili”, pensieri ereditati, saperi comuni o paradossali che loro mettono a prova, sviluppano, o fragilizzano; e ne producono a sua volta, non per offrire modelli da applicare, ma casi da mobilizzare, pensieri ormai disponibili. Questà disponibilità definisce una pratica intellettuale, gli oggetti che essa fa nascere (questa forma sensibile che prendono nel saggio le operazioni mentali), un ritmo legato ad ogni individualità nell’atto di pensare, un modo di porsi davanti al tempo. Spiega anche l’irritazione suscitata nel mondo del sapere moderno da questo genere profondamente temporale, con il suo ritmo singolare, la sua situazione culturale, ma anche la sua precarietà e, di conseguenza, il sospetto di anacronismo che lo accompagna.
Equilibrium fluctuations for the disordered harmonic chain perturbed by an energy conserving noise
Marielle Simon
Mathematics , 2014,
Abstract: We investigate the macroscopic behavior of the disordered harmonic chain of oscillators, through energy diffusion. The Hamiltonian dynamics of the system is perturbed by a degenerate conservative noise. After rescaling space and time diffusively, we prove that energy fluctuations in equilibrium evolve according to a linear heat equation. The diffusion coefficient is obtained from the non-gradient Varadhan's approach, and is equivalently defined through the Green-Kubo formula. Since the perturbation is very degenerate and the symmetric part of the generator does not have a spectral gap, the standard non-gradient method is reviewed under new perspectives.
Hydrodynamic limit for the velocity flip model
Marielle Simon
Mathematics , 2012,
Abstract: We study the diffusive scaling limit for a chain of $N$ coupled oscillators. In order to provide the system with good ergodic properties, we perturb the Hamiltonian dynamics with random flips of velocities, so that the energy is locally conserved. We derive the hydrodynamic equations by estimating the relative entropy with respect to the local equilibrium state modified by a correction term.

Carvalho, Thiago Caldi de;Gianini, Reinaldo José;
Revista Brasileira de Epidemiologia , 2008, DOI: 10.1590/S1415-790X2008000300014
Abstract: introduction: analyzing the waiting time for certain elective surgeries (saphenectomy, cholecystectomy, hemorrhoidectomy, and hysterectomy) according to hospital type, the present study intends to find if there are differences in health care. methods: a cross-sectional study was performed in sorocaba with 40 individuals from a private hospital and 40 from a public hospital, interviewed in october and november 2005. results: a longer waiting time was observed for the following categories: public hospital (5.5 months; p<0.001), lower education (3.5 months; p<0.001), lower income (spearman=-0.4426; p<0.001), residence out of sorocaba (2 months; p=0.009), and saphenectomy (5 to 7 months; p=0.04). adjusted for confounding, comorbidity, income, education, or residence variables, waiting time in public hospitals still was significantly longer (a difference of at least 4.93 months, when adjusted for income; 95%ci 3.4-6.4; p<0.001). conclusion: there was a relevant inequity in health care related mainly to the type of health care provider.
Estudio de un portafolio en la frontera de media-desviación estándar no observable
Eneas A. Caldi?o García
Análisis Económico , 2005,
Abstract: En este artículo se demuestra que si un portafolio p está en la frontera generada por N instrumentos financieros, entonces el portafolio p está en la frontera generada por cualquier subconjunto de M (M < N) de los N instrumentos financieros y el mismo portafolio p. También se demuestra que si existe un portafolio q de K portafolios que está en la frontera generada por una colección infinita numerable de instrumentos financieros, entonces el portafolio q está en la frontera generada por los K portafolios y cualquier subcolección finita de la colección infinita de instrumentos financieros. Se ilustra la utilidad de estos resultados al probar empíricamente el CAPM (Capital Asset Pricing Model) y una versión del APT (Arbitrage Pricing Theory).
