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...

We measured the air uorescence yield as a function of pressure with electrons between 1.4 MeV and 1000 MeV by means of a 90 Sr source and an electron beam. Results indicate that the uorescence yield is proportional to electron energy loss from 1.4 MeV to 1000 MeV. The dE dx relativistic rise in air is detected. We describe the pressure temperature dependency of air uorescence by a formula deriv...

Phase coherence between geomagnetic activity and temperature vari7 ability from stratosphere to troposphere is quantified and statistically tested in 8 the oscillatory mode with the period 7–8 years using the ERA-40/ERA-Interim 9 and NCEP/NCAR reanalysis monthly air temperature data. Conditional phase 10 coherence is used to identify the North Atlantic Oscillation (NAO) as a mediator 11 transfe...

BACKGROUND Defining dispersal of influenza virus via aerosol is essential for the development of prevention measures. METHODS During the 2010-2011 influenza season, subjects with influenza-like illness were enrolled in an emergency department and throughout a tertiary care hospital, nasopharyngeal swab specimens were obtained, and symptom severity, treatment, and medical history were recorded...

Traditional studies of urban climate used air temperature observations from local urban/rural weather stations in order to analyze the general pattern of higher temperatures in urban areas compared with corresponding rural regions, also known as the Urban Heat Island (UHI) effect. More recently, satellite remote sensing datasets of land surface temperature have been exploited to monitor UHIs. W...

drying is a high energy consuming process. solar drying is one of the most popular methods for dehydration of agricultural products. in the present study, the performance of a forced convection solar dryer equipped with recycling air system and desiccant chamber was investigated. the solar dryer is comprised of solar collector, drying chamber, silica jell desiccant chamber, air ducts, fan and m...

Heat transfer characteristics of air flows in concentric toroidal annular tubes filled with porous media were numerically investigated. The toroidal annulus is constant walls temperature where the outer wall temperature is lower than the inlet temperature. The numerical methodology was based on the finite difference approximation method. The computations were performed for vertical and horizont...
