Use of biomass in domestic cookstoves leads to the release oxides nitrogen (NOx), nitric oxide (NO), dioxide (NO2), carbon monoxide (CO) and hydrocarbons CxHx that can be detrimental health public environment. Attainment complete combustion is best strategy for mitigating these emissions. This study sought experimentally determine effects secondary air injection on emission profiles NOx (NO & N...

The AMP-dependent stimulation of the cyanide-insensitive respiration of Paramecium mitochondria was investigated. The nucleotides exhibiting a stimulatory effect on the cyanide-insensitive oxidation of pyruvate (+ malate) in a medium supplemented with EDTA or carboxyatractyloside were, in decreasing order of efficiency, AMP, GMP, IMP, UMP and TMP. On the other hand, ADP, ATP and cyclic AMP were...

Background & Aims of the Study: The use of qualitative indicators is one of the ways of water quality of river water. The purpose of this study is Khorramrood River of Khorramabad of water quality using water quality index (NSFWQI) and GIS that is a Geographic Information System . Materials & Methods: In this cross-sectional study, qualitative parameters needed to calculate NSFW...

Background & Aims of the Study:  Corrosion and scaling are the most common problems of water facilities. Corrosion imposes many financial and health loss on system and consumer respectively, scaling also causes clogging and head loss in network. The purpose of this study is to determine the corrosion and scaling potential of water supply sources of Qom villages. Materials &...

the effects of camp-analogue dibutyryl-camp and anticalmodulin w-7 were studied on de novo synthesis and secretion of lipids in cultures of hepatoma mcardle rh7777 cells and normal rat hepatocytes. dibutyryl-camp and w -7 separately caused a significant decrease in the secretion of de novo synthesized triacyl [3h]glycerol in both cultures of mcardle cells and rat hepatocytes. the inhibitory eff...

The adenine nucleotides, 5'-AMP and 3',5'-cyclic AMP block L cells in the S-phase of the cell cycle. The intracellular level of cyclic AMP is reduced after incubation of cells with 5'-AMP, and rates of uridine transport are increased after incubation with either 5'-AMP or cyclic AMP. On the contrary, cyclic AMP levels are increased and uridine transport decreased in cells treated with an inhibi...

Abstract. To provide long-term air pollutant exposure estimates for epidemiological studies, it is essential to test the feasibility of developing land-use regression (LUR) models using only routine quality measurement data and evaluate transferability LUR between nearby cities. In this study, we developed evaluated intercity annual-average ambient respirable suspended particulates (PM10), fine...

Abstract. Atmospheric CH4 mole fractions resumed their increase in 2007 after a plateau during the 1999–2006 period, indicating relative changes sources and sinks. Estimating by exploiting observations within an inverse modeling framework (top-down approaches) is powerful approach. It is, nevertheless, challenging to efficiently differentiate co-located emission categories sinks using alone. As...
