Solar energy is used for solar water heater in domestic and industrial purpose. Pulsating heat pipe is a fast responding, flexible and high performance thermal conducting device. The CLPHP system described in this study relies on the natural forces of gravity and capillary action and does not require an external power source. The flat plate collector consisted of a 2 mm thick sheet of Aluminum ...

The purpose of this study was to extract phenolic compounds and antioxidant activity from buckwheat with water, 50% aqueous ethanol, or 100% ethanol using microwave irradiation or a water bath for 15 min at various temperatures (23–150 C). Phenolic content of extracts increased with increasing temperature. In general, phenolic contents in microwave irradiated extracts were higher than those hea...

Abstract Solar water heating systems have been widely used around the world. However, exposure to sunlight can overheat device, affecting efficiency and durability of system. This article proposes an adaptive deck controller that protects system from overheating without compromising availability domestic hot water. heaters are considered one most effective ways reduce a home’s carbon footprint....

BACKGROUND The diagnostic criteria for bathtub drownings are not standardized, and the risk factors associated with bath-related deaths are unclear. METHODS We analyzed a Korean nationwide database of bath-related deaths that occurred between January 2008 and December 2015. Eighty-four cases were enrolled after reviewing 31,123 autopsy records. RESULTS The subjects' ages ranged from 18 to 9...

By using natural softwood pulp with higher degree of polymerization (DP=1460)as cellulose source and 1-butyl-3-methylimidazolium chloride([BMIM]Cl)ionic liquid as solvent, a novel cellulose packaging film was prepared. The effects of coagulation types, concentration of coagulation and temperature on the structure, mechanical property, permeability for oxygen and water vapor were measured. The i...

This paper proposes and analyses a new demand response technique for renewable energy regulation using smart hot water heaters that forecast water consumption at an individual dwelling level. Distributed thermal energy storage has many advantages, including high overall efficiency, use of existing infrastructure and a distributed nature. In addition, the use of a smart thermostatic controller e...
