1. ENERGETIC ANALYSIS OF AN ABSORPTION CHILLER USING NH3/LiNO3 AS AN ALTERNATIVE WORKING FLUID
Abstract This paper presents a thermodynamic model developed for a prototype absorption chiller using NH3/LiNO3 with 10 kW of nominal capacity. The study was undertaken using thermodynamic modeling based on the mass and energy balance, takes the overall heat transfer coefficients into consideration and uses the characteristic equation method. First, the resu

2. A low-protein, high carbohydrate diet induces increase in serum adiponectin and preserves glucose homeostasis in rats
Abstract: The aim of this study was investigate the effects of a low-protein, high-carbohydrate (LPHC) diet introduced to rats soon after weaning. The animals were distributed in the following groups: LPHC45: fed an LPHC diet (6%-protein, 74%-carbohydrate) for 45 days; C45: fed a control (C) diet (17%-protein, 63%-carbohydrate) for 45 days; R (Reverse): fed

3. Bioenergetics Potential of RR2 PRO Transgenic Soybean Subjected to Application of Herbicides Isolated and in Combination
ABSTRACT In Brazil, there are several crops producing oil for biofuel production, such as canola, sunflower, peanut, cotton, castor bean, soybean, among others. There are parameters that indicate the energetic and economic viability for the production of biofuels, and that can be applied, for example, in transgenic soybeans. The present study aimed to evalua

4. Bakery waste in sheep diets: intake, digestibility, nitrogen balance and ruminal parameters
The objective of the study was to evaluate the effects of bakery waste inclusion (0; 25; 50; 75 and 100%, DM basis) in proportion to corn meal in the energetic mixture of the concentrate on intake, digestibility, nitrogen balance and ruminal parameters in sheep. Five male lambs with body weight of 30 kg were used in a 5 × 5 Latin square design. Experimental

5. Balanço energético de adolescentes eutróficos e com diferentes graus de excesso de peso / Energy balance of eutrophic and overweight adolescents
Introdução: Mudanças no padrão alimentar e de atividades físicas durante os últimos 30 anos foram propulsoras para o excedente de peso em crianças e adolescentes, pois estimularam o consumo excessivo de energia combinado ao reduzido gasto energético em atividades. Ações preventivas devem ser baseadas em evidências e neste contexto, quantificar as

6. Balanço energético de um sistema integrado lavoura-pecuária no cerrado.
O presente trabalho teve como objetivo avaliar um sistema integrado lavoura-pecuária sob o ponto de vista dos fluxos globais de energia. Em uma área experimental da Fazenda Capivara, localizada na Embrapa Arroz e Feijão, foi realizada uma avaliação econômica que serviu de base para esta primeira análise energética, aqui apresentada, de uma situação

7. Metabolism and brain cancer
Cellular energy metabolism is one of the main processes affected during the transition from normal to cancer cells, and it is a crucial determinant of cell proliferation or cell death. As a support for rapid proliferation, cancer cells choose to use glycolysis even in the presence of oxygen (Warburg effect) to fuel macromolecules for the synthesis of nucleot

8. Germ band retraction as a landmark in glucose metabolism during Aedes aegypti embryogenesis
Background: The mosquito A. aegypti is vector of dengue and other viruses. New methods of vector control are needed and can be achieved by a better understanding of the life cycle of this insect. Embryogenesis is a part of A. aegypty life cycle that is poorly understood. In insects in general and in mosquitoes in particular energetic metabolism is well studi

9. BIODIGESTORES E BIOGÁS: BALANÇO ENERGÉTICO, POSSIBILIDADES DE UTILIZAÇÃO E MITIGAÇÃO DO EFEITO ESTUFA / BIODIGESTORS AND BIOGAS: ENERGETIC BALANCE, POSSIBILITING THE USE AND MITIGATION OF THE GREENHOUSE EFFECT
Biogas is a gaseous composition formed mainly by the methane gas (CH4) and by the carbon dioxide (CO2), generated especially by microbiologic processes in environment with few or no oxygen. This research was carried out on the biogas produced from the treatment of swine dejections in breathing decomposition and accumulated in the interior of biodigestors, in

10. Produção de cefamicina C por Streptomyces clavuligerus em batelada e batelada alimentada
Cephamycin C (CephC) is a natural antibiotic produced by Streptomyces clavuligerus that presents β-lactamases resistance, enzymes that clives β-lactam of antibiotics. The aim of present work was study cephamycin production by Streptomyces clavuligerus in batch and fed-batch cultivations, in order to define important parameters as culture medium and

11. Quantum effects in water: proton kinetic energy maxima in stable and supercooled liquid
A strong temperature dependence of proton mean kinetic energy was observed for liquid water around the density maximum and for moderately supercooled water. Line shape analysis of proton momentum distribution, determined from deep inelastic neutron scattering measurements, shows that there are two proton kinetic energy maxima, one at the same temperature of

12. An analysis of energetic balance of a biogasproducing System in a swine farm: implementation of a computational device / Análise de balanço energético de sistema de produção de biogás em granja de suínos: implementação de aplicativo computacional
The development of swine breeding made evident the need for greater attention to the issue of treatment and destination of swine wastes. Among the alternatives for environmental sanitation, the most advantageous one shows to be the biodigesters, since they add value to the process by means of the by-products generated: biogas, mainly made out of methane and
