1. Chilling and forcing requirement of five international fig cultivars grown in Southeastern Brazil
ABSTRACT Chill hours availability influence break dormancy, sprouting and production of temperate fruits trees in different regions. However, there are few reports on the subject for fig tree. This study aimed to evaluate the effects of the accumulated chilling hours on the physiology and dormancy release of fig cultivars. Stem cuttings of five fig cultivars

2. INGESTIVE BEHAVIOR OF SANTA INÊS SHEEP UNDER THERMONEUTRALITY AND THERMAL STRESS UPON CONSUMPTION OF SALINE WATER
ABSTRACT The consumption of saline water in semiarid regions is a recurrent situation that can affect the ingestive behavior of small ruminants. This study evaluated the ingestive behavior of Santa Inês sheep maintained in a climatic chamber under two air temperatures -25 °C within the thermal comfort zone (TCZ) and 32 °C above the TCZ - and consuming wat

3. HYBRID SYSTEM SIMULATION TO SUPPLY HEATED AIR TO A SOLAR FOOD DRYER
ABSTRACT The intermittence of solar radiation, due to continuous rainy or cloudy days, is a limitation of simple and small solar dryers. These conditions often make them impossible to use. By including storage systems (thermal accumulation) and/or auxiliary energy sources, drying processes or dehydration can be conducted continuously, even during periods of

4. Effects of Heat Stress on the Development of GABAergic Neurons in the HPG Axis of Wenchang Chicks
ABSTRACT This study conducted an in-depth investigation on the development of GABAergic neurons and their receptors in HPG axis-related target organs of Wenchang chicks under heat stress. One-day-old healthy Wenchang chicks were randomly divided into control (CK) and heat stress (HS) groups. Chicks in the HS group were placed in a 40±0.5°C climatic chamber

5. Stability-indicating capillary zone electrophoresis assay for the analysis of linezolid in tablets
A simple and fast alternative methodology using capillary zone electrophoresis (CZE) to analyze linezolid and its cationic photodegradation products in tablets has been developed. The separation was carried out on fused silica capillary and conducted using 100 mM formic acid (pH 3.0) and by applying 30 KV voltage. Detection was performed at UV 254 nm. The op

6. Neuro-fuzzy Hybrid System for Monitoring Wood Moisture Content During Drying
ABSTRACT The heterogeneous behavior of wood during drying is a process difficult to control. The objective of this study was to evaluate the accuracy of the neuro-fuzzy hybrid system for monitoring wood moisture during drying. Eucalyptus urophylla x Eucalyptus grandis samples (2 x 2 x 4 cm) were saturated and dried in climatic chamber for 15 days. Basic den

7. INFLUÊNCIA DO ENVELHECIMENTO ACELERADO EM FLARES MAGNÉSIO/PTFE/FPM
Magnesium/PTFE/FPM decoy flares, also named conventional flares, were designed in order to protect combat aircraft from the threat caused by infrared-guided missiles. Adverse storage or transport conditions may cause reactions that deteriorates chemical properties of the conventional flares, causing the aging and compromising its performance. The aim of this

8. Fuzzy modeling in the prediction of climate indices and productive performance of quails kept in climate chamber
ABSTRACT With the demand in the production at large-scale food, confinement of animals has become a necessity of the productive process because of the increase in production capacity and optimization of the spaces reserved for creations. In this context, the aim of this study was the development and validation of models using fuzzy logic for predicting clima

9. Biology and reproductive capacity of Spodoptera eridania (Cramer) (Lepidoptera, Noctuidae) in different soybean cultivars
This study aimed to evaluate the development, survival and reproductive capacity of Spodoptera eridania in four soybean cultivars. The experiment was conducted in the laboratory, in a climatic chamber at 25 °C ± 1 °C, 70 ± 10% relative humidity and 12 h photophase. The cultivars used were: FMT Tabarana, BRS/MT Pintado, FMT Tucunaré and Monsoy 8757, all

10. Bands of respiratory rate and cloacal temperature for different broiler chicken strains
The objective of this investigation was to estimate ideal bands of respiratory rate and cloacal temperature for broiler chicken strains during the rearing period and to evaluate the influence of time of exposure on bird physiological variables under different thermal stress conditions. The research was conducted in a climatic chamber during the six weeks of

12. Estudo de um sistema de análise de preferências climáticas para animais convencionais de laboratório por tecnologia de ventilação microambiental e avaliações biológicas. I. Avaliação da eficiência de um protótipo, para o estudo de parâmetros ambientais, resultados parciais verificados em ratos (Rattus norvegicus) / A climatic chamber employing Intracage Ventilation System to evaluated house condition of laboraroty animals and to biological assays in thermoregulation studies. Partial evaluation in rats (Rattus norvegicus)
Projects concerned with laboratory animals facilities usually adopt narrow range of ventilation and climatization variables to assure the define ambient. Such projects are concerned to the animal room (macro-environmental ambient) and this technology have a limitated operation to reach the micro-environmental (animal cages) ambients. The development of the i
