Neurological outcomes among pesticide applicators
The acute nervous system toxicity of organophosphate (OP) pesticides is well described. However, the reported long-term effects of OP pesticides on the nervous system are inconsistent. This inconsistency may be due to imprecise estimates of pesticide exposure, variability of central nervous system (CNS) and peripheral nervous system (PNS) assessment, small samples, and poor control of confoundi...
متن کاملCalibration of beta-particle-emitting ophthalmic applicators
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...
متن کاملA dosimetric study of Leipzig applicators.
PURPOSE To obtain the absolute dose-rate distribution in liquid water for all six cup-shaped Leipzig applicators by means of an experimentally validated Monte Carlo (MC) code. These six applicators were used in high-dose-rate (HDR) afterloaders with the "classic" and v2 (192)Ir sources. The applicators have an inner diameter of 1, 2, and 3 cm, with the source traveling parallel or perpendicular...
متن کاملNeurotoxicity among pesticide applicators exposed to organophosphates.
OBJECTIVES An epidemiological study of 90 male pesticide applicators licensed in New York was conducted to investigate the effect of exposure to organophosphate pesticides on the peripheral nervous system. METHODS A cohort of farmers and pesticide applicators from New York State were questioned off season (November 1988-February 1989) and again during the spraying season (April 1989-August 19...
متن کاملHigher-order Constraint applicators for Music Constraint Programming
This paper studies how constraints are applied to the score in a musical constraint satisfaction problem (CSP). How can we control which variable sets in the score are affected by a given constraint? Our overall objective is to produce a highly generic music constraint system, where users can define a wide range of musical CSPs, including rhythmic, harmonic, melodic and contrapuntal problems. E...
