Persistent organochlorine pollutants (POPs) are ubiquitous, bioaccumulative compounds with potential endocrine-disrupting effects. They cross the placental barrier thereby resulting in in utero exposure of the developing fetus. The objective of this study was to investigate whether maternal serum concentrations of polychlorinated biphenyls (PCBs) and p,p'-dichlorodiphenyldichloroethylene (p,p'-...
The authors analyzed the relation between lactation history, organochlorine serum levels-in particular, 2,2-bis(p-chlorophenyl)-1,1,1-trichloroethane (DDT) and 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (DDE)-and the risk of breast cancer within a subsampe from a larger breast cancer case-control study conducted among women living in Mexico City, Mexico, between 1990 and 1995. From the origin...
This case-control study was designed to investigate the relationship between polychlorinated biphenyls (PCBs) and 1,1-dichloro-2,2*-bis(p-chlorophenyl)ethylene (DDE) and breast cancer risk in Connecticut. Cases were incident breast cancer patients who were either residents of Tolland County or who had a breast-related surgery at the Yale-New Haven Hospital in New Haven County. Controls were ran...
در این مقاله یک مدل ریاضی برای مسئله سیستم تولیدی همکارانه ساخت بر اساس سفارش با رعایت انصاف تخصیص بارهای تولید طراحی شده است. اهداف اصلی مدل، کمینهسازی هزینههای کل و حداکثر استفاده از منابع بهمنظور عادلانه شرایط عدمقطعیت کنترل پارامترهای غیرقطعی روش برنامهریزی فازی شده نتایج نشان میدهد افزایش نرخ عدمقطعیت، مییابد. ازآنجاکه ظرفیت کارخانهها ثابت است، مقدار تقاضا، هر کارخانه نیز میی...
Dynamic differential evolution (DDE) for shape reconstruction of perfect conducting cylinder (PEC) buried in a half-space is presented. Assume that a conducting cylinder of unknown shape is buried in one half-space and scatters the field incident from another halfspace where the scattered filed is measured. Based on the boundary condition and the measured scattered field, a set of nonlinear int...
Critical Windows p,p ́-DDE May Alter Fetal Neurodevelopment DDT has been widely used to control mosquitoborne malaria since the late 1940s. The compound and metabolites such as p,p ́-DDE linger in the environment for decades; even in areas where DDT has been banned, these neurotoxic chemicals are still detected in human blood, fat, breast milk, and umbil ica l cord blood. Researchers examined the...
Adipose tissue samples from polar bears (Ursus maritimus) were obtained by necropsy or biopsy between the spring of 1989 to the spring of 1993 from Wrangel Island in Russia, most of the range of the bear in North America, eastern Greenland, and Svalbard. Samples were divided into 16 regions corresponding as much as possible to known stocks or management zones. Concentrations of dieldrin (DIEL),...
Target audience. Researchers and clinicians interested in the brain’s microarchitecture and diffusion MR methods. Purpose. Generating a methodology capable of amplifying Double-Diffusion-Encoding MR’s sensitivity towards randomly oriented compartments. Introduction. Double Diffusion Encoding (DDE, Fig. 1A) [1] NMR and MRI techniques – more commonly known as Double Wave Vector (DWV) [2] or doubl...
A wide range of Sensor Networks (SNs) are deployed in real world applications which generate large amount of raw sensory data. Data mining technique to extract useful knowledge from these applications is an emerging research area due to its crucial importance but still it’s a challenge to discover knowledge efficiently from the sensor network data. In this paper we proposed a Distributed Data E...
