background: human hair can be used as an inexpensive and accessible adsorbent to remove a variety of pollutants from air. although several studies have been done on removal of formaldehyde from wastewater by human hair, to date no study has investigated using hair to remove formaldehyde from air. therefore, the aim of this study was to remove formaldehyde from synthetic contaminated air by a re...
Detecting urbanization effects on surface and subsurface thermal environment--a case study of Osaka.
Tremendous efforts have been devoted to improve our understanding of the anthropogenic effects on the atmospheric temperature change. In comparison, little has been done in the study of the human impacts on the subsurface thermal environment. The objective of this study is to analyze surface air temperature records and borehole subsurface temperature records for a better understanding of the ur...
Complex heat transfer phenomena (including unsteady state conduction, convection and solidification processes) occur in steel belt conveyer sulfur granulating method. Numerical simulation of this technique is performed via a comprehensive and multifaceted one dimensional model. Since the air situated between the adjacent sulfur pastilles is essentially stagnant, therefore, the surface tempe...
BACKGROUND Most studies of the skin and how it responds to local heat have been conducted with either water, thermodes, or dry heat packs. Very little has been accomplished to look at the interaction between air humidity and temperature on skin temperature and blood flow. With variable air temperatures and humidity's around the world, this, in many ways, is a more realistic assessment of enviro...
Experiments about the forced-air precooling of cucumbers were carried out under different operation parameters. The results show that the relation between cooling rate and air velocity can be given by power function. The linear relationship between the initial temperature of cold air and cucumbers and the final temperature of cucumbers is gained. Temperature gradient exists in different radius ...
Denis CLODIC Centre d'Energetique ·Ecole des Mines de Paris 60, boulevard Saint-Michel· F • 75272 PARIS Cedex 06 A test bench has been developed consisting in an open display-case and a refrigerating system composed mainly of four hermetic compressors, an air cross-current condenser and an evaporator. The evaporating temperature of -40°C allows to keep the temperature of the products at ·18°C f...

The air temperature is an essential variable in many applications related to Earth science. Sporadic spatial distribution of weather stations causes a low spatial resolution of measured air temperatures. This study focused on modeling the air diurnal temperature cycle (DTC) based on the land surface temperature (LST) DTC. The air DTC model parameters were estimated from LST DTC model parameters...
Temperature conditioning of nasal air: effects of vasoactive agents and involvement of nitric oxide.
Nitric oxide (NO) is released into nasal air, but its function is unknown. We hypothesized that nasal vascular tone and/or flow influences temperature conditioning of nasal air and that NO participates in this process. We measured nasal air temperature (via a thermocouple) and exhaled nasal NO release (by chemiluminescence) in five humans and examined the effects of an aerosolized vasoconstrict...
Environmental storage conditions, particularly air temperature, relative humidity and air velocity, have a major role in maintaining fruit and vegetable quality during cold storage. The constant low temperature, high relative humidity (RH) and moderate air flow are important to limit perishable quality. Storage temperature controls must be well calibrated to maintain a precise level of control....
