This paper describes certain changes in the heart frequency, which are produced by localized heating of various parts of the sinus venosus. It was formerly found by Gaskell (1) that the heating of the sinus venosus causes an acceleration while heating of atria and ventricle had no remarkable effect on heart rate. In this phenomenon, however, there are still some problems to be solved. One unset...

A new bonding technique is proposed by using localized heating to supply the bonding energy. Heating is achieved by applying a dc current through micromachined heaters made of gold which serves as both the heating and bonding material. At the interface of silicon and gold, the formation of eutectic bond takes place in about 5 minutes. Assembly of two substrates in microfabrication processes can...

Treatment of sewage sludge by composting for the production of materials useful as a soil amendment is a feasible method of achieving both waste disposal and agricultural enhancement simultaneously。 However, the hygienic safety of the final products is an issue which requires resolution. This study was an investigation of the effects of heating patterns on the inactivation and regrowth potentia...

Manufacturing components of fiber-reinforced thermoplastics requires three steps: heating the matrix, forming and consolidation of the composite and terminal cooling the matrix. For the heating process a pre-determined temperature distribution through the layers and the thickness of the pre-consolidated sheets is recommended to enable forming mechanism. Thus, a design for the heating process fo...

Ohmic heating offers an alternating to conventional heating because it simultaneously heats both phases by internal energy generated through electrical energy. In this process heating rate depends upon the electrical conductivity and field strength. By this method a product undergoes a minimum structural damage, retain its nutritional value. This technique gives excellent processed quality prod...

It is difficult to predict the heating time and power consumption associated with the self-heating process of lithium-ion batteries at low temperatures. A temperature-rise model considering the dynamic changes in battery temperature and state of charge is thus proposed. When this model is combined with the ampere-hour integral method, the quantitative relationship among the discharge rate, heat...

background: autoxidation is considered to be the main route of edible oil deterioration, which produces undesirable odors and flavors during storage and heating. the unpleasant flavor of oxidized oil has been attributed to primary and secondary products of unsaturated fatty acids. the microwave heating is a rapid method when compared with other methods of heating. objective: in this research, t...
