The housing market plays a significant role in the economies of countries, and as an asset price channel, is considered as one of the main channels for monetary transmission mechanism. Considering the structure of the country's economy and the characteristics of housing as a capital commodity, the assessment of the impact of housing investment on inflation is important. This research evaluates ...

diversity, accessibility and reliability are the three main factors governing the adoption of information sources by farmers in rural areas. based on the research hypothesis, the existing knowledge and information delivery system in the agricultural sector, functions far below the ever changing nature and tangible needs of existing farming systems. the main objective in this study is to determi...

Introduction Numerous studies have demonstrated the presence of potassium selective channels in membranes internal organelles. These channels are essential to a large variety of cellular processes including intracellular 2+ a signaling, protein recycling, charge neutralization and cell protection. In contrast to the sarcoplasmic reticulum + here potassium channels have been clearly ...

In this research, the impact of shoulder width and geometry of gas channel with different structures on proton exchange membrane (PEM) has been investigated using numerical method. 3D, non-isothermal was used with single straight channel geometrywhile maintaining the same boundary conditions and reaction area with addition of humidification for anode and cathode. Our study showed that an ellipt...

introduction: intracellular ph (phi) regulates essentially all aspects of cellular activities. however, it is unknown how endoplasmic reticulum (er) potassium channels sense phi. in this study, we investigate the direct effects of phi on er potassium channels. methods: we used channel incorporation into the bilayer lipid membrane method. l-α-phosphatidylcholine, a membrane lipid, was extracted ...

the world is facing severe challenges in meeting the rapidly growing demand for water resources. in addition,irrigation water which is the largest use of water in most developing countries and arid and semi arid regions, will likelyhave to be diverted increasingly to meet the needs of the households in urban areas and industry sectors whilst remaining aprime engine of agricultural growth. a lin...

atp-sensitive potassium (katp) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. there has been considerable interest in exploring katp channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. the purpose of this study was to synthesize 3,3,6,6-tet...

Zinc is a substance that regulates neural excitability by binding whit sodium channel and potassium channel. The efficiency of free zinc ion, make down the neural survival rate, reduced the peak amplitude of Na+ and make depolarization Na channel, increased the peak amplitude of transition outward k+ currents and delayed rectifier. Also it is an effective blocker of one subtype of tetrodoxine (...

this paper examines the short- and long-run effects of domestic research and development (r&d;) and foreign r&d; (throw the channels of capital goods import and foreign direct investment) on iranian economic growth using of endogenous growth models and bounds test approach to level relationship over the period of 1351-1386. bounds test approach results confirm the existence of long-run relation...
