this paper presents a theoretical model in order to determine tile expected rate of durable good`s supply over time. the social plaliner maximizes tile sum of the discount ed net benefit. subject to the stochastic fluctuation in the stock of durable goods. it turns out that a social planner increases the expected rate of supply since uncertainty increases the user's loss from the view poin...

Wheat curl mite (WCM) is the only known arthropod vector of four wheat viruses, most important which streak mosaic virus (WSMV). Host resistance to WCM and WSMV limited a small number loci, are introgressed from wild relatives often associated with linkage drag temperature sensitivity. Reports virulent populations potential resistance-breaking isolates highlight need for more diverse sources re...

Five oral agents have been approved for the treatment of chronic hepatitis B, ranging in virological potency, clinical efficacy, barrier to resistance, and side-effect profile. The degree of histological, biochemical, and serological improvement with therapy generally corresponds to the degree of suppression of serum hepatitis B virus (HBV) DNA achieved with therapy. Conversely, for agents with...

Consumption is the principal feature of Iran’s Gross National Production. Therefore, recognizing of factors that influence it is quite crucial. This article, investigates habit formation, durability, relative risk aversion and intertemporal substitution in consumption expenditures of Iranian households. For empirical study, at first, we constructed two weighted portfolio of the main assets re...

Glutaraldehyde fixation is a tissue preservation process used in the manufacture of bioprosthetic heart valves. The objective of fixation is to produce stable, durable, and biologically inert tissue that is suitable for implantation. Collagen, a principle tissue protein, provides strength and resistance to breaking stresses in tissue and plays a critical role in its long-term durability. In 198...
