A cubic equation of state for HFC-32/HFC-125 mixtures developed on the basis of our experimental data was used for thermodynamic analysis of refrigeration cycles using this blend. The influence of composition changes on energy efficiency and Total Equivalent Warming Impact (TEWI) was studied. Comparisons of this blend with HCFC-22 and other alternative refrigerants were also carried out. Detail...

The size of the Ga-Mampa wetland (1 km), in the Olifants River catchment in South Africa, was halved between 1996 and 2004. This jeopardizes the ecological integrity and influences the benefits people obtain from the wetland. This study therefore analysed the economic values of the provisioning services derived from the Ga-Mampa wetland and evaluated their contribution to the livelihoods of loc...

Owing to the remarkable progress of molecular techniques, heterozygosity-fitness correlations (HFCs) have become a popular tool to study the impact of inbreeding in natural populations. However, their underlying mechanisms are often hotly debated. Here we argue that these "debates" rely on verbal arguments with no basis in existing theory and inappropriate statistical testing, and that it is ti...

I develop a general equilibrium model in which the quality of household financial decisions is endogenously determined by the incentives to exert effort in learning about financial opportunities. The model generates predictions for asset market participation and returns across households. Moreover, search for financial returns enables the model to generate a more skewed equilibrium wealth distr...

Background: The National Health Accounts keep track of all healthcare related activities from the beginning (i.e. resource provision), to the end (i.e. service provision). This study was conducted to address following questions: How is the Iranian health system funded? Who distribute the funds? For what services are the funds spent on?, What service providers receive the funds? Methods: The...

BACKGROUND Non-alcoholic fatty liver disease (NAFLD), characterized as excessive lipid accumulation within hepatocytes, is growing in prevalence. The exploitation of effective drugs for NAFLD has been proven challenging. Herein, we aimed to establish a dietary model of hepatic steatosis using transparent zebrafish larvae in which high-throughput chemical screens could be conducted. METHODS Ze...
