Exposure to air pollution in city centers is of major concern because of its health-risks to urban dwellers, trafficcorridor users and even to in-transit commuters. The steady growth in traffic is the major source of toxic air pollutants in urban centers these days. Therefore, studying exposure to air pollutants in urban centers is of special interests to environmental health scientists. This s...

Motivated by the high speed of real-time data acquisition, computational power, and low cost of generic PCs and embedded-PCs running Linux, this thesis addresses new methods and approaches to fault detection, model identification, and control. Fault detection. A series of faults was introduced into a 3-Ton roof-top airconditioning unit (RTU). Supply and condenser fan imbalance were detected by ...

Searching, PubMed (accessed Nov. 10, 2015) for “Air pollution” and “Health” resulted in 26,156 citations. Since the 1930 Meuse Valley episode in Belgium, Donora 1948 and the London fog of December 1952, the number of studies showing adverse health effects of short and long term exposure to outdoor air pollution has grown. This review looks at historical air pollution studies to get a general ov...

air pollution is one of the major threats to environment in the present time. increase in degree of urbanization is a major cause of this air pollution. due to urbanization, vehicular activities are continuously increasing at a tremendous rate. mobile or vehicular pollution is predominantly degrading the air quality worldwide. thus, air quality management is necessary for dealing with this seve...

the air quality in shiraz was assessed based on a one-week passive sampling campaign.during the first week of the summer 2003, about 400 passive samplers were used in groups of two andthree, so that 187 sampling stations covered all of shiraz. pollutant gases including so2, no2 and btx(benzene, toluene and xylene) were sampled by diffusive sampling tubes. collected samples wereanalyzed and poll...

a two-week tunnel study was conducted in monterrey, mexico during june 2009 to characterizevolatile organic compound (voc) emissions from the local vehicle fleet and estimate the correspondingemission factors (efs). the loma larga tunnel (llt), a 532 meter-long structure that is mainly used by lightduty gasoline-powered vehicles was used as the experimental set-up. ambient air samples (2-hour a...

introduction drying foods, fruits and vegetables is a suitable method to reduce post-harvest losses of the crops. drying is considered as a simultaneous heat and mass transfer process. various physical, chemical and nutritional changes occur during drying of foods and are affected by a number of internal and external heat and mass transfer parameters. external parameters may include temperature...

NINOMIYA, ISHIO, AYA IRISAWA, AND NAOKO NISIMARU. Nonuniformity of sympathetic nerve activity to the skin and kidney. Am. J. Physiol. 224(Z) : 256-264. 1973.-The effects of baroceptor reflex on the sympathetic nerve activity (SNA) to the skin and kidney were compared in anesthetized cats. Grouped SNA synchronous with cardiac cycle and respiration was not the major pattern in the skin nerve. Wit...

The Large Hadron Collider (LHC), a 26.7 km circumference superconducting accelerator equipped with high-field magnets operating in superfluid helium below 1.9 K, has now fully entered construction at CERN, the European Laboratory for Particle Physics. The heart of the LHC cryogenic system is the quasi-isothermal magnet cooling scheme, in which flowing two-phase saturated superfluid helium remov...
