In epidemiologic studies, much of the variation in disease risk estimates associated with occupational pesticide exposure may be due to variation in exposure classification. The authors compared five different methods of using interview information to assess occupational pesticide exposure in a US-Canada case-control study of neuroblastoma (1992-1994). For each method, exposure assignment was c...

We derive the asymptotic behavior of the occupation measure Z(B1) of the unit ball for superBrownian motion started from the Dirac measure at a distant point x and conditioned to hit the unit ball. In the critical dimension d = 4, we obtain a limiting exponential distribution for the ratio Z(B1)/ log |x|.

background: to develop nursing education and promote nursing strategies, there is a need for a staff with positive attitude. the present study was conducted to compare the attitudes among clinical nurses and nursing students toward the nursing profession. materials and methods: in this descriptive study, 313 clinical nurses and 81 nursing students (total n = 394) of tehran, iran, were selected ...

We derive the asymptotic behavior of the occupation measure Z(B1) of the unit ball for super-Brownian motion started from the Dirac measure at a distant point x and conditioned to hit the unit ball. In the critical dimension d = 4, we obtain a limiting exponential distribution for the ratio Z(B1)/ log |x|.

OBJECTIVE To evaluate associations between binge-eating disorder (BED) and somatic illnesses and determine whether medical comorbidities are more common in individuals who present with BED and comorbid obesity. METHOD Cases (n = 850) were individuals with a BED diagnosis in the Swedish eating disorders quality registers. Ten community controls were matched to each case on sex, and year, month...

Computational Fluid Dynamics (CFD) is a computational technology that enables researchers to study the dynamics of things that flow. By using CFD, it is possible to build a computational model that represents a system under study. It not only predicts fluid flow behavior, but also the transfer of heat, mass, phase change, chemical reaction, mechanical movement, and stress or deformation of ...

The influence of internal tubes present in the fluidized bed on its hydrodynamic behavior was examined in this study. One tube was completely immersed in the bed of 650 m glass beads at 10 cm above the air distributor in the 15 cm inner diameter fluidized bed column of aspect ratio 1. The pressure fluctuations signal was collected over 300 s and was consequently analyzed by the both statistical...

Regional haemodynamic control by the cardiovascular baroreceptors was examined in dogs anaesthetized with 1 + MAC halothane in oxygen (1%). The open-loop relationships between carotid sinus pressure (CSP) and regional haemodynamics in the iliac, renal, mesenteric, aortic and coeliac beds were examined before vagotomy, following vagotomy and following thoracotomy. Around the carotid sinus reflex...
