The region of the Indian Ocean and adjacent countries has received increased attention in recent years in the context of particulate air pollution. Aerosol samples were collected over the equatorial Indian Ocean during a one-year-long sailing cruise that covered the northeast and southwest monsoons, and an intermonsoon period. The concentrations of airborne particulate matter (PM), selected met...

The objective of this paper is to provide an analysis of particulate metal emissions in the USA. The analysis will identify natural and industrial sources, environmental standards, emission trends, and controls of particulate emissions. Since the majority of airborne metal emissions originate from metal industries and electric utility facilities, environmental and worker assessments of exposure...

  Background: The role of arthroscopic partial meniscectomy (APM) for painful degenerative meniscal tears (PDMT) is currently controversial. To define the rate of early (1 to 5 years) conversion to total knee replacement (TKR) and their predictors after APM for PDMT in patients with knee osteoarthritis and more than 50 years of age. Methods: Retrospective cohort study of patients more than...

α-L-Aspartyl-D-phenylalanine methyl ester (L, D-APM) and α-D-aspartyl-L-phenylalanine methyl ester (D, L-APM) are diastereomers of aspartame (N-L-α-Aspartyl-L-phenylalanine-1-methyl ester, L, L-APM). The Joint FAO/WHO Expert Committee on Food Additives has set 0.04 wt% as the maximum permitted level of the sum of L, D-APM and D, L-APM in commercially available L, L-APM. In this study, we develo...

Context: Airborne particulate matter (PM) attracts heightened attention due to its implication in various diseases, especially cardiovascular diseases. Although numerous epidemiological studies have been published worldwide developing countries on risks associated with exposure PM, such are still scarce as Saudi Arabia. Objective: To examine the association between concentration of airborne and...

Environmental conditions and airborne myco£lora were measured concurrently in 10 turkey confinement houses during warm and cold weather. The following variables in the environment were measured: numbers of feedand litter-associated yeast and mold fungi, temperature, relative humidity, airspeed, carbon dioxide and ammonia concentration, airborne bacteria, and airborne particulate mass, particle ...
