The balance between metabolic heat production, heat removal by blood flow, and heat conductance defines local temperature distribution in a living tissue. Disproportional local increases in blood flow as compared with oxygen consumption during functional brain activity disturb this balance, leading to temperature changes. In this article we have developed a theoretical framework that allows ana...

Expert Leaders in a Fast-Moving Environment This paper is an attempt to understand the effects of leaders on organizational performance. We argue for an ‘expert leader’ model of leadership. We differentiate between four kinds of leaders according to their level of inherent knowledge and industry experience. After controlling for confounding variables, teams led by leaders with extensive knowled...

were reported to have occurred in Hamah, 35 deg. lat. N., long. 37 deg. E.?a town of 40,000 inhabitants, situated on the banks of the Orontes, and lying on the high road between Aleppo and Damascus. How the disease should have appeared in so inland a place without its being known to exist in any part of Turkey or any of the provinces contiguous to it was a mystery, and the first reports were dis-

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 ...

Torgac Cave, located in south-central New Mexico is remarkable for at least three reasons: its extraordinary gypsum speleothems, its large bat population, and the unusually cold temperatures within the cave. It has been proposed that the presence of the bats and the speleothems may be related to the anomalous temperatures observed in the cave. This paper reports the results of a five week study...

Broiler chickens in Brazil are generally reared from 1 to 42 days when they are exposed to procedures such as fasting, harvesting, crating and transport to slaughter. Maintaining homeostasis is of great importance for broiler survival under harsh environment especially prior to slaughter. Heat loss varies in the distinct parts of the body during the growth period, and it is related to the air t...

The benefits of rooftop greening are ascertained in thermal perspective. It effectively reduces the near surface ambient temperature and the reflected irradiation from the rooftop slab, thus increasing the thermal comfort environment above the lawn and reduces the heat transferred through the rooftop slab. The former effect enables the potential usage of the rooftop spaces for human activity an...
