1. Temperatura de la superficie terrestre en diferentes tipos de cobertura de la Región Andina Colombiana
This study assessed the relationship of Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI) with land surface temperature (LST), using Landsat images of La Vieja river watershed, in the Andean region of Colombia. We evaluated land covered by Andean forest, forest plantation, coffee, pasture and urban area. Negative corr

2. Análise térmica e energética de uma edificação residencial climatizada com sistema de Fluxo de Refrigerante Variável -VRF Fernando Pozza
O trabalho apresenta uma análise térmica e energética de uma edificação localizada na zona bioclimática 1, que compreende as cidades mais frias do Brasil. A análise foi desenvolvida com o auxílio do programa de simulação dinâmica de edificações EnergyPlus em que foi determinado o consumo anual de energia elétrica de toda a edificação existent

3. Thermal comfort and energy efficiency in Budget Hotels / Conforto térmico e eficiência energética em hotéis econômicos
This work aims to evaluate the energy efficiency and comfort level, in airconditioned environments of budget hotels, from international chains, in São Paulo, Brazil. The evaluation was directed to the apartments which are the hotels main product featuring air conditioning, even though the climate conditions and usage profile dont determine its need. One hot

4. Estudo da termografia por infravermelho: aplicaÃÃes na engenharia e determinaÃÃo de parÃmetros termofÃsicos e geomÃtricos de materiais
Infrared thermography is used to obtain the temperature distribution on the surface of objects. This information can be used for qualitative or quantitative analysis. The main objective of this work is to present fields where the use of thermography analysis is successful. Several examples are shown in which changes on the superficial temperature distributio

5. ANÁLISE DE UM SISTEMA DE PRODUÇÃO SIMULTÂNEA DE ELETRICIDADE, FRIO E CALOR / ANALYSIS OF A SYSTEM FOR THE SIMULTANEOUS PRODUCTION OF ELECTRICAL ENERGY, HEAT AND COLD
The simultaneous production of electric energy, heat and cooling capacity from the primary fuel burning on a heat engine (trigeneration) can emerge as a promising strategy, from the energy and project points of view, mostly, in food and chemistry industries. The present work describes the experimental study of a vapor compression system for chilled water pro

6. Effect of thermal stress on Frank–Starling relations in humans
The Frank–Starling ‘law of the heart’ is implicated in certain types of orthostatic intolerance in humans. Environmental conditions have the capacity to modulate orthostatic tolerance, where heat stress decreases and cooling increases orthostatic tolerance. The objective of this project was to test the hypothesis that heat stress augments and cooling a

7. Differences in the processes of beta-lactoglobulin cold and heat denaturations.
The changes in beta-lactoglobulin upon cold and heat denaturation were studied by scanning calorimetry, CD, and NMR spectroscopy. It is shown that, in the presence of urea, these processes of beta-lactoglobulin denaturation below and above 308 K are accompanied by different structural and thermodynamic changes. Analysis of the NOE spectra of beta-lactoglobul

8. Calorimetry of apolipoprotein-A1 binding to phosphatidylcholine-triolein-cholesterol emulsions.
The thermotropic properties of triolein-rich, low-cholesterol dipalmitoyl phosphatidylcholine (DPPC) emulsion particles with well-defined chemical compositions (approximately 88% triolein, 1% cholesterol, 11% diacyl phosphatidylcholine) and particle size distributions (mean diameter, approximately 1000-1100 A) were studied in the absence and presence of apol
