2. Thermal comfort monitoring in aviaries by a real-time data acquisition system
RESUMO O conforto térmico no interior de instalações de criação de frangos de corte é essencial na obtenção de bons resultados nesta atividade de produção. A avaliação das condições termodinâmicas adequadas requer a medição e controle, geralmente implicando em custos e manutenção especializada. Neste trabalho, objetivou-se monitorar a dist

3. INFLUENCE OF DIFFERENT THERMAL ENVIRONMENTS ON THE PERFORMANCE OF LAYING HENS DURING THE INITIAL STAGE OF REARING
ABSTRACT This study was conducted with the aim of assessing the effects of different ambient temperature values on the performance of laying birds from one to 42 days of age in order to obtain optimal comfort temperatures. A total of 864 laying hens were distributed in four climatic chambers with different temperature ranges. One of the chambers was maintain

4. Physiological responses of growing pigs to high ambient temperature and/or inflammatory challenges
ABSTRACT Global warming is one of the major environmental threats facing the world in the 21st century. This fact will have a significant impact on pig production due to its direct effects on welfare, health, and performance of pigs. Besides, the effects of high temperatures will presumably become more important over the next decades due to the development o

5. Human thermal comfort: an irreversibility-based approach emulating empirical clothed-body correlations and the conceptual energy balance equation
Exergetic analysis can provide useful information as it enables the identification of irreversible phenomena bringing about entropy generation and, therefore, exergy losses (also referred to as irreversibilities). As far as human thermal comfort is concerned, irreversibilities can be evaluated based on parameters related to both the occupant and his surround

7. Experimental study of the heat transfer between the passenger and the seat of vehicles by means of instrumented maniquim. / Estudo experimental da troca de calor entre o passageiro e o banco de veículos utilizando manequim instrumentado.
Vehicles seats acclimatization systems have been lately developed and delivered as microclimate solutions in response to the personal comfort increasing demand. The influence of such systems use on the improvement of passengers satisfaction with the ambient thermal comfort is well recognized, either heating or cooling the seat. In the present work the heat t

8. Instrumentação e identificação de um ambiente predial visando controle preditivo do conforto térmico / Instrumentation and building identification aiming predictive control of thermal comfort
The technological basis of Ambient Intelligence is a network of processing units that collect sensor information, process them and act on the environment through actuators, providing the occupants a diversity of services. In this scenario, this manuscript presents a first-principles structured identification approach for a thermal environment consisting of a

9. 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

10. Avaliação das perdas e dos fatores bioclimáticos atuantes na condição de espera pré-abate de frangos de corte / Evaluation of losses and bioclimatic factors present on poultry preslaughter lairage condiction
Nowadays, Brazilian poultry industry has a challenge of reducing losses. However, the disinformation about the critical points limits this advance, mainly on preslaughter operations. Therefore, studies must be carried through diagnosing scenes and identifying the critical points, which is found the biggest losses. Therefore, the objective of this work was to

12. Applied intelligent system used for controlling acclimatization of dairy housing / Sistema inteligente aplicado ao acionamento do sistema de climatização em instalações para bovinos leiteiros
The objective of this study was to develop a specialist system for controlling the acclimatization system in free-stall dairy housing. The modeling procedure used animal physiological data (rectal temperature and respiratory track) as function of environmental data inside housing (air temperature and relative humidity, and temperature and humidity index).
