By tracking conformational transitions of individual ion channel proteins, single-channel recordings allow the observer to deduce gating mechanisms, as well as estimate rate constants of microscopic gating steps. For most ion channels, gating mechanisms are complex, comprising multiple stable open (O) and closed (C) conformations among which conformational transitions may follow a network of po...

this experiment was conducted in order to study the influence of different levels of municipal solid waste compost and nitrogen rate on grain quality of sweet corn (zea mays l. saccharata) and some soil properties under marvdasht conditions during growing season of 2008-2009. the experiment was arranged as split plots based on a randomized complete block design with two factors and three replic...

In recent years, increasing environmental concerns focused greater attention on the development of biodegradable materials. A thermoplastic starch derived from bioresources, sugar palm tree was successfully developed in the presence of biodegradable glycerol as a plasticizer. Sugar palm starch (SPS) was added with 15-40 w/w% of glycerol to prepare workable bioplastics and coded as SPS/G15, SPS/...

Background: Evidence suggests a relation between short sleep duration and obesity. Objective: We assessed energy balance during periods of short and habitual sleep in normal-weight men and women. Design: Fifteen men and 15 women aged 30–49 y with a body mass index (in kg/m) of 22–26, who regularly slept 7–9 h/night, were recruited to participate in this crossover inpatient study. All participan...

Ecotourists appreciate nature and are willing to learn about nature and ecology. Th erefore ecotourism is often seen as a product package that supports sustainable tourism development. Th is study contributes to existing research in the fi eld of ecotourism as it investigates how travel motives and environmental concern of mountain tourists infl uences their actual demand for ecotourism. A surv...
