15 صفحه اولDispersion of Cd , Cr , Cu , Ni , Pb and Zn Particles in a Turbulent Air Flow
From the prospective of air quality, the dispersion of heavy metal pollutants has gain importance in recent past. The pollutants disperse from the point of release to the distant areas transporting contaminants there. Heavy metal pollutants in the form of fine particulate matter can be harmful to human health through inhalation. In this study the lateral dispersion of heavy particles is predict...
متن کاملDistribution of Cr, Pb, Cd, Zn, Fe and Mn in Lake Victoria sediments, east Africa.
The presence of many metals at trace or ultra-trace levels in the human environment has received increased global attention (WHO 1977; Hutton 1982; IRPTC 1984). Surveillance of concentrations of heavy metals in the environment is of global interest since elements like cadmium, lead and mercury are listed as environmenta]ly dangerous chemical substances. Sediments as a sink for pollutants are wi...

متن کاملUltrastructural Aspects of Spermatogenesis in Phalloceros caudimaculatus (Teleostei, Poeciliidae)
The aim of the present study was to analyze the ultrastructural aspects of spermatogenesis in Phalloceros caudimaculatus, during cell proliferation. The parenchyma is organized morphologically as lobular restricted spermatogonial testis. Spermiogenesis in this species is characterized by four morphological stages of development (spermatids S1 through S4). The mature spermatids and spermatozoa h...
