Bispectral index (BIS) is a reliable parameter for measuring depth of hypnotic level during anesthesia. Convective air warming system is an effective equipment to maintain normothermia during operation. We report falsely elevated BIS value due to convective air warming system while undergoing kidney transplantation.

What is air quality? Zhang (2005) defines air quality as the degree of pollution of clean air. Clean air is the air that is free from impurities. Air quality can be determined by measuring the concentration of pollutants in the air. The lower the concentration of airborne pollutants, the better is the air quality. Auvermann (2006) defined air pollutants as compounds or materials that, when susp...

stationary sources are reponsible to 96.8 of sox and 70.1 percent of nox in tehran. there are more than 70 thousands factories located in tehran region. economic policy measures such as, charges, subsidies, and non-compliance fees, and also marketable permits, bubble policy, offets, netting and reforms in banking, are recommended. automobiles produce 71.2 percent of total air pollution in tehra...

PURPOSE Autoclaves and UV sterilizers have been commonly used to prevent cross-infections between dental patients and dental instruments or materials contaminated by saliva and blood. To develop a dental sterilizer which can sterilize most materials, such as metals, rubbers, and plastics, the sterilization effect of an atmospheric pressure non-thermal air plasma device was evaluated. MATERIAL...

Air pollution is an important public health problem in Europe and there is evidence that it exacerbates health inequities. This calls for effective strategies and targeted interventions. In this study, we conducted a systematic review to evaluate the effectiveness of strategies relating to air pollution control on public health and health equity in Europe. Three databases, Web of Science, PubMe...

This study aims to optimize extraction and drying conditions of fig syrup. Drying was done in a pilot scale two-fluid nozzle spray dryer. A total of 27 experiments were conducted with varying inlet air temperatures, air flow rates, and also a maltodextrin (MD)- low methoxyl pectin (LMP) ratios. While feed rate, feed temperature, and compressed air flow rate of the atomizer were kept constant. T...

Inside air ventilation ducts of the confined space such as subway stations become contaminated by various contaminants and particular matters after long time operation. The accumulated various pollutants at inner duct surface easily transport and cause secondary air contamination and injure subway passengers’ respiratory system and health. In fact, only periodic duct cleaning works can improve ...

Since enactment of the 1990 amendments to the Clean Air Act, the control and removal of volatile organic compounds (VOCs) from contaminated air streams have become a major public concern (1). Consequently, considerable interest has evolved in developing more economical technologies for cleaning contaminated air streams, especially dilute air streams. Biofiltration has emerged as a practical air...

The effect of air temperature, air velocity, and sample shapes (circle and square with the same cross-sectional area) on kinetic drying of potato slices in a tunnel dryer was investigated experimentally and a suitable drying model was developed. The experiments of drying of potato slices were conducted at an air temperature of 45-70°C with an air velocity 1.60 and 1.81 m sec(-1). Results showed...
