The main objective of this research was to conduct an assessment of ergonomic-related problems in oilrigs in a desert environment. A checklist, physical audit and medical records were used in the investigation. The results showed significant health, environment and work-related problems that could be attributed to ergonomic deficiencies in the work system of the oilrig. Some major ergonomic iss...

Recently, planthoppers outbreaks have intensified across Asia resulting in heavy rice yield losses. The problem has been widely reported as being induced by insecticides while other factors such as global warming that could be potential drivers have been neglected. Here, we speculate that global warming may increase outbreak risk of brown planthopper (Nilaparvata lugens Stål.). We present data ...

OBJECTIVE To clarify whether deaths associated with hot and cold days are among the frail who would have died anyway in the next few weeks or months. DESIGN Time series regression analysis of annual deaths in relation to annual summaries of cold and heat. SETTING London, UK. PARTICIPANTS 3 530 280 deaths from all natural causes among London residents between October 1949 and September 200...

Many probes have been proposed to map out the behaviour of hot and dense hadronic matter and also to highlight its eventual transition to a plasma of quarks and gluons. It is outside the scope of this talk to review them all or even partially: we will concentrate on electromagnetic radiation and more specifically on the emission of thermal lepton pairs. Those suffer minimal final state interact...

Aim: Tea is usually consumed at two temperatures (as hot tea or as iced tea). However, the importance of drink temperature on the cardiovascular system and on metabolism has not been thoroughly investigated. The purpose of this study was to compare the cardiovascular, metabolic and cutaneous responses to the ingestion of caffeinated herbal tea (Yerba Mate) at cold or hot temperature in healthy ...

The study objective was to identify the circumstances where there was risk of contamination of food (hot dogs) prepared and sold on the streets and to establish a preventive action through the creation of key surveillance sites. Data were collected from 20 vending sites using interviews, questionnaires, observations of food handling and storage, and temperature and pH measurements of both meat ...

Summer extreme heat threatens the health of individuals, especially persons who are involved in outdoor activities. Ensuring the normal function of a city, bus drivers are among those who participate in outdoor physical activities and are exposed to excessive heat in hot summer weather. This qualitative study was performed to explore professional bus drivers' in-depth views of extreme heat risk...

Effect of hot and cold dust charge on the propagation of dust-acoustic waves (DAWs) in unmagnetized plasma having electrons, singly charged ions, hot and cold dust grains have been investigated. The reductive perturbation method is employed to reduce the basic set of fluid equations to the Korteweg-de Vries (KdV) equation. The effect of cold (hot) dusty plasma density nc (nh) and the charge num...

UNLABELLED Handovers permeate healthcare delivery systems. They are critical for patient safety and continuity of care, but also for logistics and clinical efficiency. Poor handovers can cause reduced efficiency, delayed discharge or time to operation, and contributes to patient harm. The Objective was to conduct a human factors assessment (HFA) using a systems approach to study the handover pr...

A dynamic model predicting human thermal responses in cold, cool, neutral, warm, and hot environments is presented in a two-part study. This, the first paper, is concerned with aspects of the passive system: 1) modeling the human body, 2) modeling heat-transport mechanisms within the body and at its periphery, and 3) the numerical procedure. A paper in preparation will describe the active syste...
