background; various industries produce and discharge wastes containing different heavy metals into the environment. apart from using living biomass, dead and dried biomasses have been introduced as a new field of biotreatment technology. method; the cadmium (cd) (ii) removal characteristics of live (growing), dead (autoclaved), and oven-dried biomasses of aspergillus versicolor were examined as...

Research papers usually contain a significant number of links to other resources. For the most part, they reference other printed research papers, but there are also a non-trivial number of links to resources on the World Wide Web. Unlike printed research papers, references to WWW resources may become invalid after time. The server containing the page may be taken offline, be temporarily unavai...

recently, special type of fuel cells has been developed that operates in a dead end mode. working in this condition, the dead-end fuel cell is supplied withhydrogen almost at the same rate of consumption. it is noteworthy to mention thatall of the water transport mechanisms have been considered in this simulation.water accumulation that is directly proportional to the cell current is of a great...

The amount of natural resources in the Earth's environment is in flux, which can trigger catastrophic collapses of ecosystems. How populations survive under nutrient-poor conditions is a central question in ecology. Curiously, some bacteria persist for a long time in nutrient-poor environments. Although this survival may be accomplished through cell death and the recycling of dead cells, the im...

background: human peripheral blood nk cells constitutively express cd56 and cd16 antigens. peripheral blood nk cells seem to be strongly related with decidual nk cells, and may reflect the decidual nk cell functional status. there are varied reports concerning the relationship between nk cell cytotoxicity in women with recurrent spontaneous abortion. objective: to study nk activity in women wit...

TNFα is one of the inflammatory cytokines which plays an important role in activating the Caspase and inducing the apoptosis. This cytokine which is secreted in inflammations, induces the NO production in macrophages and leads to differentiation of the macrophages to the epithelioid and giant cells. One of the most important factors which stimulates the TNFα secretion, is LPS and th...

chemical flooding, especially alkaline/surfactant/polymer flooding, is of increasing interest due to the world increasing oil demand. this work shows the aspects of using alkaline/surfactant/polymer as an enhanced oil recovery method in the porous media having a high dead-end pore frequency with various dead-end pore parameters (such as opening, depth, aspect ratio, and orientation). using glas...
