The relationship between the concentration of heavy metals and physicochemical factors was studied in the fine-grained sediments of the tidal section of the Mehran delta where mangrove trees have grown. Surface sediments of the tidal zone of the Mehran delta were sampled. The grain size distribution, calcium carbonate, organic matter contents, pH/Eh, and heavy metals concentration were determin...

a new class of nonlinear set-valued variationalinclusions involving $(a,eta)$-monotone mappings in a banachspace setting is introduced, and then based on the generalizedresolvent operator technique associated with$(a,eta)$-monotonicity, the existence and approximationsolvability of solutions using an iterative algorithm and fixedpint theory is investigated.

Nitric oxide (NO) and carbon monoxide (CO) seem to be neurotransmitters in the brain. The colocalization of their respective biosynthetic enzymes, neuronal NO synthase (nNOS) and heme oxygenase-2 (HO2), in enteric neurons and altered intestinal function in mice with genomic deletion of the enzymes (nNOS(Delta/Delta) and HO2(Delta/Delta)) suggest neurotransmitter roles for NO and CO in the enter...

The TCR-gamma and -delta chains of six murine hybridomas were compared by one-dimensional SDS-PAGE and two-dimensional NEPHGE/SDS-PAGE analysis. This allowed the identification of three distinct gamma chains (gamma a, gamma b, and gamma c) and three distinct delta chains (delta a, delta b, and delta c). Four gamma/delta chain combinations (gamma a delta a, gamma b delta b, gamma b delta c, and ...

Perovskite structures including oxygen vacancies are the most important group of the oxygen preamble membranes. These membranes have potentially attractive applications in the membrane reactors for partial oxidation of methane. Doping Perovskite phase in order to increase the oxygen vacancies and oxygen permeation, besides Perovskite structure stability, has been the main approach of the recent...

Hepatitis Delta virus (HDV) is a degenerate RNA virus or virusoid and a satellite of Hepatitis B virus (HBV). Three distinct genotypes are described for HDV; genotype I is distributed worldwide but other genotypes appear to be more restricted geographically. In the present study, an RT-nested PCR method was set up to detect delta infection from serum samples. Moreover, the target amplified sequ...

world's coastlines are the most dynamic natural environments and diverse extraordinary and unique processes are active in this area. one of results of these processes is the formation and evolution of alluvial fans and delta. the studied areas include hormoz strait coastal, shour, jalaby and hassan-langi river delta which in the form of a strip with a varying width covers the areas from th...

The rearrangement and expression of T cell receptor (TCR) gene segments occurs in a highly ordered fashion during thymic ontogeny of T lymphocytes. To study the regulation of gene rearrangement within the TCR alpha/delta locus, we generated transgenic mice that carry a germline human TCR delta minilocus that includes V delta 1, V delta 2, D delta 3, J delta 1, J delta 3, and C delta segments, a...
