Patient warming significantly decreases the risk of surgical site infection. Recently there have been concerns that forced air warming may interfere with unidirectional airflow, potentially posing an increased risk of infection. Our null hypothesis was that forced air and radiant warming devices do not increase the temperature and the number of particles over the surgical site when compared wit...

BACKGROUND Fanger's PMV equation is the result of the combined quantitative effects of the air temperature, mean radiant temperature, relative air velocity, humidity, activity level and clothing insulation. METHODS This paper contains a comparison of suit dresses and summer clothes in terms of thermal comfort, Fanger's PMV equation. Studies were processed in the winter for an office, which lo...

This paper studies the heating load and thermal comfort distribution in a typical office with a mixed radiant and convective heating system for two different locations of radiant heat sources. Accurately estimating the heating load in a mixed heating space requires careful consideration of the energy balance on each room surface and the comfort level in the space. A pure radiant heating system ...

The warming and humidification of inspired gases for ventilated neonates are routine. There are no data on the temperature of the gasat the airway opening in ventilated neonates. Is the inspired gas temperature at the airway opening, as expected and set on the humidifier, around 378C?We aimed to measure temperature at the airway opening and compare this with the circuit temperature. This was an...

One of the most critical variables in field thermal comfort measurements is mean radiant temperature which typically measured with a standard 150 mm black globe thermometer. This also reference instrument required for assessment heat stress conditions by means well-known Wet Bulb Globe Temperature index (WBGT). However, one limitations this method represented relatively long response time. why ...

This study examined the influences of aluminized (Type A) and non-aluminized firefighters’ protective clothing (Type B, C, D and CON) on physiological and subjective responses in radiant heat. Total clothing weight was 6.24, 6.38, 6.06, 5.76 and 3.82 kg for Type A, B, C, D and CON, respectively. Eight firefighters performed exercise at an air temperature of 30°C with 50%RH. Three bouts of 10 mi...

the public spaces in our today’s lives involve many sorts of activities, and the design of such spaces requires a wide range of studies. one of the critical studies in our country, due to its climatic variety, is about the thermal comfort of public outdoor spaces. this article has been conducted to investigate about possible architecture and landscape architecture design measurements which coul...
