based on two integration steps, an optimization framework is proposed in this work for the synthesis and design of complex distillation sequence. the first step is to employ heat integration in sequence and reduce the heat consumption and total annual cost of the process. the second one is to increase the exergetic efficiency of sequence by generating power in implemented expanders in sequence....

Limited information is available on occupational exposures during routine, nonoutage work activities in coal-fueled power plants. This study evaluated occupational exposures to the principal contaminants in the facilities, including respirable dust (coal dust), arsenic, noise, asbestos, and heat stress. The data were collected over a 3-month period, during the summer of 2001, in 5 facilities th...

The purposes of this review are to show pathophysiological mechanisms for heat illness during working in a hot environment and accordingly provide some preventive considerations from a viewpoint of body fluid homeostasis. The incidence of the heat illness is closely associated with body temperature regulation, which is much affected by body fluid state in humans. Heat generated by contracting m...

Th is paper discusses human thermoregulation and how this relates to health problems during exposure to climatic stress. Th e heat exchange of the body with the environment is described in terms of the heat balance equation which determines whether the body heats up, remains at stable temperature, or cools. Inside the body the thermoregulatory control aims at creating the right conditions of he...

The temperature within the deep tissues of the body (core temperature) is normally maintained within a range of 36.0°C to 37.5°C (97.0°F to 99.5°F).12 Within this range, there are individual differences and diurnal variations; internal core temperatures reach their highest point in late afternoon and evening and their lowest point in the early morning hours (Fig. 9-11). Virtually all biochemica...

Microgrid (MG) is considered as a feasible solution to integrate the distributed energy sources. In this paper, optimal scheduling of a grid-connected MG is investigated considering different power sources as combined heat and power (CHP) units, only power and heat generating units, and battery storage systems. Two different feasible operating regions are considered for the CHP units. In additi...

Introduction: Magnetic nanoparticle (MNP) hyperthermia is a promising cancer treatment approach. It is based on the evidence that by injecting MNPs such as Fe3O4 in the tumor and subjecting them to an alternating magnetic field, they release heat, generating temperatures up to 42°C that can kill cancer cells by apoptosis, usually with lowest damage to normal tissue. In previous...

Am J Physiol Regul Integr Comp Physiol 291: R533–R540, 2006. First published March 23, 2006; doi:10.1152/ajpregu.00887.2005.— Core body temperature (Tb) is influenced by many physiological factors, including behavioral state, locomotor activity, an...

In this paper a methodology developed for the generation of transient compact models of packages and heat sinks from measured thermal transient results is described. The main advantage of generating dynamic compact models solely from measured results is the time-gain: the lengthy transient simulations, suggested by the DELPHI methodology can he omitted. After summarizing the procedure of genera...
