On the basis of Braaten and Segel’s representation of the electromagnetic dispersion relations in a QED plasma we check the numerical accuracy of several published analytic approximations to the plasma neutrino emission rates. As we find none of them satisfactory we derive a new analytic approximation which is accurate to within 4% where the plasma process dominates. The correct emission rates ...
OBJECTIVES Noninvasive urothelial carcinoma of the bladder (UCB) causes an enormous economic burden to public health systems due to its life-long character and frequent recurrences. While white light (WL) cystoscopy is considered to be the gold standard for transurethral resection of the bladder, photodynamic diagnostic (PDD) has been shown to improve final outcome. Escalating healthcare costs ...

this study was focused on measuring air pollutants emission from factories producing the asphalt related products in delijan industrial estate, which is the main center of asphalt related products in iran. emissions of four factories were analyzed for air pollutants using a stack analyzer, testo 360, testo co., and germany. the average concentration of all measured stacks for pm, thc, co, nox, ...
Biogenic corrosion of sewers represents a cost of about 10% of total sewage treatment cost in Flanders (Belgium) and is further increasing. In the past, research has resulted in a number of prevention methods, such as injection of air, oxygen, H(2)O(2), NaClO, FeCl(3) and FeSO(4). The possibility of biological oxidation of sulfide using nitrate as the electron acceptor has also been explored in...
ship exhaust emission inventories and their associated externalities constitute valuableinformation resources towards policy making and management of the influence exerted by shipping on airquality. to this extent, the container terminal at the greek port of piraeus by virtue of its shipping significanceand its urbanised character was selected in order to provide an estimation of the emissions ...
AIMS To study the cost of the follow-up of hypertension in primary care (PC) using clinical blood pressure (CBP) and ambulatory blood pressure monitoring (ABPM), and to analyse the cost-effectiveness (CE) of both methods. MAJOR FINDINGS AND PRINCIPAL CONCLUSION Good control of hypertension was achieved in 8.3% with CBP (95% CI 4.8-11.8) and in 55.6% with ABPM (95% CI 49.3-61.9). The cost of o...
BACKGROUND Asthma is associated with high indirect costs due to lower work productivity and higher absenteeism and presenteeism. OBJECTIVES To study loss of productivity measured using the lost workday equivalent (LWDE) index and health care utilization in asthmatics depending on age, geographical location, time period, severity, and level of asthma control. PATIENTS AND METHODS In this cro...
