  Introduction: The incidence of heat stress is one of the most common problems in work environments as well as many different industries. The exposure of workers to heat results in heat strain. The purpose of the present study was to validate the Perceptual Strain Index through determining its relationship to the Physiological Strain Index and the Wet Bulb Globe Temperature Index und...

The physiological equivalent temperature, PET, is a thermal index derived from the human energy balance. It is well suited to the evaluation of the thermal component of different climates. As well as having a detailed physiological basis, PET is preferable to other thermal indexes like the predicted mean vote because of its unit ( degrees C), which makes results more comprehensible to urban or ...

A physiological strain index (PSI) based on heart rate (HR) and rectal temperature (Tre) was recently suggested to evaluate exercise-heat stress in humans. The purpose of this study was to adjust PSI for rats and to evaluate this index at different levels of heat acclimation and training. The corrections of HR and Tre to modify the index for rats are as follows: PSI = 5 (Tre t - Tre 0). (41.5 -...

The determine the effect of different foods on the blood glucose, 62 commonly eaten foods and sugars were fed individually to groups of 5 to 10 healthy fasting volunteers. Blood glucose levels were measured over 2 h, and expressed as a percentage of the area under the glucose response curve when the same amount of carbohydrate was taken as glucose. The largest rises were seen with vegetables (7...

A physiological strain index (PSI), based on rectal temperature (Tre) and heart rate (HR), capable of indicating heat strain online and analyzing existing databases, has been developed. The index rates the physiological strain on a universal scale of 0-10. It was assumed that the maximal Tre and HR rise during exposure to exercise heat stress from normothermia to hyperthermia was 3°C (36.5-39.5...

In areas such as medical, military and physical exercise, often physiological indexes like temperature, humidity and motion are of great interest. In work, we developed a Wireless Biomedical Sensor Network (WBSN) which is able to wirelessly monitor temperature, humidity and acceleration of a sensor terminal. The designed a sensor network provides a low power, small size and easy-to-use package ...

In this study, 10 normal volunteers and 5 sports-trained paraplegics with lesions between T6 and L2 were studied whilst walking with axillary crutches and knee-anlde-foot orthoses. All subjects walked at their preferred speed on a figureof- eight track. Normal subjects also walked at slower and faster speeds. Oxygen consumption, heart rate and rating of perceived exertion were measured. In...

Introduction: Heat stress is a critical problem in hot industries, especially in incredibly hot climates. It can greatly impair the work process and put the health of workers at risk. This study aims to investigate the applicability of the WBGT index in determining the allowable working time in very hot weather conditions in one of the steel industries in Ahvaz. Material and Methods: This stud...

Identification of easily measured physiological traits contributing to yield under specified environmental conditions would benefit genotypic selection for grain sorghum. A field experiment was conducted to determine broad-sense heritability and expected genetic advance, and to examine the relationships of grain yield with 11 physiological traits related to developmental periods, vegetative gro...

Background and Objective: Urban traffic, while affecting human health, causes physiological and biochemical changes in plants. The aim of this study was to investigate the bioaccumulation potential of Pb and Cd and assess air pollution tolerance index for a number of plants grown high traffic areas of Yazd. Materials and Methods: This cross-sectional, descriptive-analytical study was perfo...
