This service provides calibrations for ^^Sr + beta particle ophthalmic applicators. The calibration determines the average surface absorbed-dose rate to water over the active area of the applicator. The technique used is to measure current per unit mass of air at the active surface with an extrapolation ionization chamber, and to convert this into absorbed-dose rate with Bragg-Gray cavity ioniz...

allergic rhinitis is the most common cause of allergic diseases. the recent guidelines of allergic rhinitis and its impact on asthma (aria) group, classified it to intermittent (less than 4 days per week and for less than 4 weeks) and persistent (more than 4 days per week or lasting more than 4 weeks regardless of the number of days per week). the present study evaluates the patients with aria ...

BMJ Case Reports Published online: 13 December 2012 doi:10.1136/bcr-2012007830 DESCRIPTION Following a seemingly straightforward procedure to place the necessary applicators (comprising the central tandem into the uterine cavity, and the right and the left ovoids into the lateral vaginal fornices), this patient of cervical-carcinoma,...

FEMLAB and MicroWaveLab, two finite element solvers, are evaluated in the context of needs of microwave power engineering. Limitations of the codes are identified by simulation of characteristics of applicators based on circular and rectangular waveguides as well as coaxial-to-ridgedand coaxial-to-double-ridged waveguide transitions. Results are verified by QuickWave-3D.

In 1997 we published an article in EHP on cytogenetic and thyroid hormonal changes in 49 heavily exposed workers applying ethylene bisdithiocarbamate (EBDC) fungicide to tomatoes, based on a collaborative study done by the U.S. National Institute for Occupational Safety and Health and the Institute of Public Health in Mexico (Steenland et al. 1997). EBDCs are a common class of fungicides (e.g.,...

While precautionary efforts are being made to minimize human health problems associated with agricultural pesticides, the continued occurrence of occupational poisoning from these chemicals raises major concerns among stakeholders. Information gap on human health problems associated with pesticides poses major obstacles to making informed policy decisions, particularly in developing countries w...
