1. MATHEMATICAL MODELLING AND IMMEDIATE AND LATENT QUALITY OF NATURAL IMMATURE COFFEE UNDER DIFFERENT DRYING CONDITIONS
ABSTRACT This work aimed to study the immediate and latent effects of different relative humidities on the quality of dried coffee fruits, describe the drying kinetics of natural immature coffee (Coffea arabica L.), and evaluate the mathematical model that best fits the experimental drying data. The drying was carried out in a fixed layer dryer coupled to a

2. Development of paints with infrared radiation reflective properties
Abstract Large buildings situated in hot regions of the Globe need to be agreeable to their residents. Air conditioning is extensively used to make these buildings comfortable, with consequent energy consumption. Absorption of solar visible and infrared radiations are responsible for heating objects on the surface of the Earth, including hou

5. Thermal performance of a castor oil foam as insulating material inside the roof : study case in the city of Ilha Solteira, Brazil / Desempenho termico da espuma poliuretana a base de oleo de mamona utilizada em componentes da edificação (subcoberturas) : estudo em Ilha Solteira, SP
The aim of this work is to describe an experimental study using castor oil foam as an insulating material inside the roof. The castor oil foam inside the roof is an appropriate natural recycled material as a passive cooling strategy as opposite to the burning of fossil fuels for air conditioning (AC) and mechanical ventilation. The expected result of this re

7. Análise numérica do escoamento em uma sala retangular ventilada por um jato horizontal de parede
The present work investigates the three-dimensional turbulent airflow in a room ventilated by a horizontal wall jet. The geometry of Nielsen s experiment (Nielsen et al., 1978), for which experimental and numerical results for some turbulence models are available in the current literature, has been adopted in this work. This experiment consists of a rectangu

8. Resfriamento evaporativo e condicionamento de ar convencional: estudo experimental comparativo / Evaporative cooling and conventional air conditioning: a comparative experimental study
This experimental research aims to compare the evaporative cooling with the conventional air conditioning in terms of levels of humidity, reduction in indoor air temperature, and energy consume. The experiment was conducted in three purpose-built test cells, similar in structure, which were exposed to the same climatic conditions and showed the same indoor a

9. Resistencia a união e padrão de condicionamento em esmalte de sistemas adesivos autocondicionantes aplicados de forma passiva ou ativa / Microtensile bond strength evaluation of self-etchiung adhesive systems on enamel
The aim of this study were evaluate the bond strength and conditioning pattern obtained from different self-etching adhesive systems applied on enamel by active and passive forms. 100 bovine incisors were sectioned in 6x6mm fragments from the buccal enamel surface. The specimens were divided into 10 groups (n= 1 O). It was used one single bottle adhesive sys

10. Modeling and experimental evaluation of parallel flow micro channel condensers
This paper reports results obtained in a theoretical and experimental study involving micro channel/louvered fin condensers for automotive applications. A simulation model has been developed based upon three zones related to the thermodynamic states of the refrigerant in the condenser. Experiments with condensers have been performed in a set up developed for
