25. Thermal comfort zones for starter meat-type quails
The objective of this study was to determine thermal comfort ranges, as evaluated by air temperature and black-glove temperature and humidity index (BGTHI), for starter meat-type quails. Nine hundred quails were randomly distributed into five environmental chambers. Each chamber was programmed to provide different temperatures weekly. The following thermal e

26. Performance of free-range chickens reared in production modules enriched with shade net and perches
An experiment was carried out to evaluate the effect of environmental enrichment in a free-range chicken production system on live performance as a function of microclimate, physiological parameters, and performance parameters. Four production modules were divided into four pens with 10 birds each, totaling 60 birds. The following treatments were applied: ac

27. A Multi-objective, active fuzzy force controller in control of flexible wiper system
Chaotic vibration has been identified in the flexible automotive wiper blade at certain wiping speeds. This irregular vibration not only decreases the wiping efficiency, but also degrades the driving comfort. A reliable nonlinear system identification namely nonlinear auto regressive exogenous Elman neural network (NARXENN) was adopted in first stage of this

28. A decision-tree-based model for evaluating the thermal comfort of horses
Thermal comfort is of great importance in preserving body temperature homeostasis during thermal stress conditions. Although the thermal comfort of horses has been widely studied, there is no report of its relationship with surface temperature (T S). This study aimed to assess the potential of data mining techniques as a tool to associate surface temperature

29. Fuzzy Modeling of Annoyance Caused by Aircraft Noise Using Laeqd and Laeqn Metrics
ABSTRACT: Airport noise presents a major environmental impact arising from aircrafts airport activities, being one of the most complex and difficult mitigation problems. From the environmental point of view, airports cause serious problems to the population. Annoyance caused by noise was evaluated from the Day-Night Level (DNL) metrics proposed by Schultz. H

30. Efeitos do uso e cobertura do solo sobre o conforto higrotérmico / Effects of the use and soil cover on the hygrothermal comfort
Given the importance of obtaining an urban design based on the microclimate and the possibility of the use of trees as a factor in mitigation of urban distress, this study evaluated the effect caused by three different spatial arrangements of urban forests and the use and occupation on soil in temperature and humidity of the environment in surroundings area.

31. Análise da influência de parâmetros acústicos na inteligibilidade da fala: um estudo em salas de aula de escolas municipais de João Pessoa.
Researchs in the area of environmental comfort conducted in schools reported that, considering the thermophysical variables, the acoustic variable is more important than the other variables, especially in relation to thermal, luminous and indoor air quality variables, since this is the variable that is directly tied to speech intelligibility, with impacts on

34. Some aspects of chicken behavior and welfare
Brazil is the world leader in broiler production and export. It achieved this position mainly to its excellent supply chain structure and climate, which favor poultry and grain production throughout its territory. Although Brazilian egg production is not as important as broiler production, this segment presents great potential of increasing its share in the
