Background and Objective: Heavy metals are the most frequent pollutants of urban soils. In general, human health and especially children are directly at risk if the soil is being accidentally ingested orally or nasally. Therefore, this study was conducted to assess potential ecological risk index (RI) of Pb, Cd, Cr and Cu in surface soils of urban parks in Tehran City in 2016. Materials and Me...

Background and Objective: Soils and sediments contamination with trace and toxic elements lead to potential ecological risk and adverse effects on human health and so have been the cause of increasing concern worldwide. Therefore, this study was carried out to potential ecological risk assessment of As, Cd, Ni and V in surface sediments of Khazar Abad, southern parts of Caspian Sea in 2019. M...

A population of cells that express mast cell markers, including the membrane protein p161, but that lack expression of the high affinity IgE receptor, Fc epsilon RI, can be routinely grown from bone marrow. Ionomycin, but not IgE immune complexes, causes these cells to release serotonin and to express IL-3 and IL-13 mRNA, consistent with their being FC epsilon RI-deficient mast cells. These p16...

Introduction: Water quality is essential for industries because they play an important role in countries’ economic development. Groundwater is one of the most widely used resources, and when the ionic constituents were increasing higher than the allowable limit, it increases the cost of maintenance and production in the industries. Materials and Methods: In order to evaluate groundwater corros...

This article reports the results of two studies aimed at testing and refining a procedure for estimating willingnessto-pay based monetary values of safety using the contingent valuation method. In spite of the fact that respondents were given the opportunity to discuss various safety issues and key concepts in focus group meetings held in advance of individual interviews, and were also given am...

$EVWUDFW: Software architecture is nowadays regarded as the first step to achieving software quality. The main task of the architect is to translate the quality requirements into a software architecture. An important step in this process is to assess whether the architecture actually satisfies these quality requirements. The purpose of this paper is to explore which architectural choices suppor...

Specific isoforms of the cAMP-dependent protein kinase are preferentially expressed within discrete neuronal regions in mouse brain (Cadd and McKnight (1989) Neuron 3, 71-79) suggesting that these subunits might have different functional properties. We have used recombinant techniques to express and purify the type I regulatory subunits, RI alpha and RI beta, the catalytic subunits C alpha and ...
