Working fluids have been considered as the vital factor in the aspects of environmental protection and energy conservation for all the heating and refrigerating systems. The mainly on using hydrochlorofluorocarbons and hydrofluorocarbon working fluids as well as their substitutes in the transitional period are not environmentally friendly, which possess the ozone depletion potential and larger ...

‘Gala’ apples were treated after harvest with heat (38°C for 4 days), and then wound-inoculated with the pathogen Penicillium expansum and the antagonist Pseudomanas syringae, or one of two yeast antagonists, to reduce postharvest decay. After storage for 7 days at 20°C or 3 months at 1°C, the least decay was found on fruit where wounds had been allowed to cure by heat treatment (38°C) or cold ...

Declining cancer incidence and mortality rates in the United States (U.S.) have continued through the first decade of the twenty-first century. Reductions in tobacco use, greater uptake of prevention measures, adoption of early detection methods, and improved treatments have resulted in improved outcomes for both men and women. However, Black Americans continue to have the higher cancer mortali...

Environmental pollution is now a serious problem in many developing countries. One approach to combat the problem is to implement various pollution control policies. However, due to a lack of adequate quantitative models, the economic impacts and effectiveness of many pollution control policies are still unknown. This article uses the computable general-equilibrium (CGE) approach to develop an ...

Primary aldosteronism is a frequent form of secondary hypertension that had long been considered relatively benign. Experimental and clinical evidence collected in the last two decades, however, has clearly demonstrated that this endocrine disorder is associated with excess cardiovascular and renal complications as compared to essential hypertension. These complications reflect the ability of i...

Introduction: Most of people are exposed to ionizing radiation sources during their lifetime including background, cosmic or man-made beams like radiation used in nuclear medicine and radiology. Due to unavoidable use of ionizing radiation in diagnosis and treatment of diseases, designing and correct implementation of radiation protection principles in order to reducing its har...
