13. A protensão como um conjunto de cargas concentradas equivalentes. / Prestressing as equivalent concentrated loads group.
This work is a study about the representation of the prestressing through a CELG (Concentrated Equivalent Loads Group) in order to determine the internal forces and displacements in prestressed structures, due to prestressing. This study considers the concept of prestressing, deviation forces and immediate loss of prestressing. Furthermore some alternative m

14. AnÃlise de projeto de turbina eÃlica de grande porte para as condiÃÃes climÃticas da regiÃo Nordeste do Brasil
The main aim of this work is to quantify the modifications on the energy generation and extreme and fatigue loads of a wind turbine operating particularly in a well concentrated wind speed distribution near to the mean value. This particular meteorological condition is commonly found in the Northeast region of Brazil. The wind speed distribution is modeled i

15. Analise das capacidades de resistencia, força e velocidade na periodização de modalidades intermitentes
Laboratory and field evaluations have been used to determine the athletic physical state and to interfere in the training of specific physical capacities to the sport. Our goal was to show the importance of physical evaluation in the training schedule for intermittent modalities during the competition season. A total of 41 subjects with 18 ± 1 year old (und

16. TRAÇADO AUTOMÁTICO DE ENVOLTÓRIAS DE ESFORÇOS EM ESTRUTURAS PLANAS UTILIZANDO UM ALGORITMO EVOLUCIONÁRIO / AUTOMATIC TRACING OF ENVELOPES IN PLANAR STRUCTURES USING A EVOLUTIONARY ALGORITHM
The objective of this work is to develop a tool for obtaining envelopes of internal forces due to load-trains in the FTOOL software. Usually, envelopes are obtained through interpolation of limiting values on pre- selected sections along the structure. These values are obtained based on the positioning of the loadtrain in relation to influence lines of inter

17. EVALUACIÓN DEL EFECTO DE CARGAS CONCENTRADAS EN VIGAS DE ACERO A TRAVÉS DE ALGORITMOS DE REDES NEURALES / ESTUDO DO EFEITO DE CARGAS CONCENTRADAS EM VIGAS DE AÇO ATRAVÉS DE ALGORITMOS DE REDES NEURAIS / EVALUATION OF THE EFFECTS OF CONCENTRATED LOADS ON STEEL BEAMS THROUGH NEURAL NETWORK TECHNIQUES
Las cargas concentradas en vigas de acero son frecuentemente encontradas en la práctica de la ingeniería civil. En las situaciones donde el local de aplicación de la carga es fijo, enrijecedores transversales de alma pueden ser usados para aumentar la resistencia, mas deben ser evitados siempre que sea posible por razones económicas. Para cargas móviles

18. Long-lasting training-effect (EPDT) of concentrated strenght training loads investigation on volley-ball athletes from "infanto-juvnil" and juvenil age groups" / O efeito posterior duradouro de treinamento (EPDT) das cargas concentradas de força : investigação a partir de ensaio com equipe infanto juvenil e juvenil de voleibol
The Long-Lasting Training Effect (EPDT) of concentrated strength training loads - Investigation on Volley-Ballathletes from "infanto-juvenil"and "juvenil age groups" The main purpose of this study was to analyse the phenomena of the load of strength training (A) during the annual training cycle. It was used a longitudinal approach aiming to control the dynam

19. Ecologia e historia natural das interações entre palmeiras, epifitas e frugivoros na região do pantanal matogrossense
The occurrence of vascular epiphytes and hemiepiphytes on three palm species in the Pantanal and Chapada dos Guimarses, Central Brazil was investigated. The sampling areas at the Pantanal were concentrated near Poconé and Barão de Melgaço. At Chapada dos Guimarães, sampling took place in the vicinity of the town, and in the area of influence of the Hydro

20. Osmoprotective activity for Escherichia coli in mammalian renal inner medulla and urine. Correlation of glycine and proline betaines and sorbitol with response to osmotic loads.
Escherichia coli are protected against hypertonic NaCl by human urine. We have shown that this is due in part to the presence of glycine betaine and proline betaine. Several investigators have proposed that betaines and sorbitol are concentrated in the cells of the renal inner medulla where they exert a protective role against urea and extracellular osmotic

21. Direct Effects of Salicylate on Renal Function in the Dog
Sodium salicylate was administered to anesthetized dogs in doses sufficient to produce concentrations in plasma comparable to those common in human salicylate toxicity. Salicylate administration increased the rates of excretion of water, sodium, and chloride in the urine. Salicylate administration also increased the rate of excretion of potassium so that its

22. Resistance to dietary-induced hypercholesterolemia exhibited by a unique strain of New Zealand white rabbits.
The search for a precise metabolic explanation for the capacity of some individuals to resist the development of dietary-induced hypercholesterolemia, thus avoiding attendant cardiovascular atherosclerotic complications, has long been the focus of our research. From 1 New Zealand white rabbit that failed to show any cholesterolemic response, we have, over th
