BACKGROUND Numerous studies show associations between fine particulate air pollutants [particulate matter with an aerodynamic diameter ≤ 10 μm (PM₁₀)] and mortality in adults. OBJECTIVES We investigated short-term effects of elevated PM₁₀ levels on infant mortality in Flanders, Belgium, and studied whether the European Union (EU) limit value protects infants from the air pollution trigger. ...
BACKGROUND Although numerous studies have demonstrated links between particulate matter (PM) and adverse health effects, the chemical components of the PM mixture that cause injury are unknown. OBJECTIVES This work characterizes spatial and temporal variability of PM(2.5) (PM with aerodynamic diameter < 2.5 microm) components in the United States; our objective is to identify components for a...
To investigate the effect of brinzolamide on diurnal fluctuations in the intraocular pressure (IOP) in patients on latanoprost ophthalmic solution prospectively was aimed. Eleven patients with primary open angle glaucoma were enrolled in this study. The subjects were admitted to the hospital and had their IOPs measured over 24 hours (10 AM, noon, 2 PM, 4 PM, 6 PM, 8 PM, 10 PM, midnight, 3 AM, 6...
4 Preventive maintenance (PM) is a maintenance program with activities initiated at predetermined intervals, or 5 according to prescribed criteria, and intended to reduce the probability of failure, or the degradation of the functioning 6 of an item. In the literature, a number of PM models have been introduced to depict the effectiveness of PM. Based on 7 these models, approaches to scheduling...
BACKGROUND Air pollution data in Bangkok, Thailand, indicate that levels of particulate matter with aerodynamic diameter < or = 10 microm (PM(10)) are significantly higher than in most cities in North America and Western Europe, where the health effects of PM(10) are well documented. However, the pollution mix, seasonality, and demographics are different from those in developed Western countrie...
OBJECTIVE Prospective memory (PM) refers to the ability to remember to perform actions in the future. Schizophrenia spectrum disorders show impairments in PM but neural correlates of these impairments remain unclear. The present study aimed to examine brain activation during PM to identify impairments in individuals with schizotypal personality features. METHOD Nineteen participants with schi...
We grow $^{28}$Si/SiGe heterostructures by reduced-pressure chemical vapor deposition and terminate the stack without an epitaxial Si cap but with amorphous Si-rich layer obtained exposing SiGe barrier to dichlorosilane at 500 {\deg}C. As a result, heterostructure field-effect transistors feature sharp semiconductor/dielectric interface support two-dimensional electron gas enhanced more uniform...
