The current paper determines heavy metals in sediments of six freshwater wetlands of greater Dhaka district from November 1999 to September 2000. The sampling took place in summer, rainy season, and winter, wherein for each season five soil samples were collected from the wetland at a depth of 0 – 15 cm. To assess the status of heavy metal pollution in the sediments, geo-accumulation factor (Ig...

abstract research and development (r&d;) spending plays a major role in innovation, raising productivity and increasing economic growth. the purpose of this paper is to investigate the impact of r&d; spending on growth and total factor productivity (tfp) in iran's agricultural sector. we estimate growth and productivity models using auto-regressive distributed lag (ardl) approach and data over ...

in this study for the first time a new description of compressibility factor is rendered based on the virial expansion. the compressibility factor as a function of m-factor is qualitatively and quantitatively expressed. at first, we present how may the third, fourth and higher order virial coefficients be logically ignored in order to simplify the virial equation. the results show, when the com...

background little is known about the possible influence of demographic and histological risk factors on the survival of patients with esophageal and gastric cancer. objectives based on the available registry and follow-up information, this study compares 1-5 year survival rate of gastric and esophageal cancer. patients and methods through a concurrent (prospective) cohort study, all 366 patient...

this article present the result from a study of two sediment cores collected from theenvironmentally distinct zones of ces. accumulation status of five toxic metals: cadmium (cd), chromium(cr), cobalt (co), copper (cu) and lead (pb) were analyzed. besides texture and chns were determined tounderstand the composition of the sediment. enrichment factor (ef) and anthropogenic factor (af) wereused ...

background: thrombophilia is a main predisposition to thrombosis due to a procoagulant state. several point mutations play key roles in blood-clotting disorders, which are grouped under the term thrombophilia. these thrombophilic mutations are methylenetetrahydrofolate reductase (mthfr, c677t, and a1298c), factor v leiden (g1691a), prothrombin gene mutation (factor ii, g20210a), and plasminogen...

background: considering the increasing number of patients with hemophilia and infrastructure requirements for a comprehensive approach, development of a recombinant factor has become a milestone. the objective of this study was to assess the safety, efficacy and non inferiority of safacto (recombinant factor viii) compared with plasma-derived factor in the treatment of hemophilia a. methods: 10 ...

background: hemophilia b is a bleeding disorder with a recessive x-linked inheritance pattern, in which the infected individuals have low levels of factor ix in their plasma. affected individuals may have bleeding episodes after trauma or spontaneously considering the plasma level of factor ix. in order to prevent these episodes and to control bleeding, they should use coagulation factor concen...
