We show the existence of a reversible, complementary and polarity dependant electric pulse-induced resistance (EPIR) switching effects in Au=YBa2Cu3O7 d ceramic superconductor interfaces. Non-volatile high and low resistance states and transition regions between them are obtained as a function of the amplitude and polarity of the pulsing voltage. Relaxation processes of the resistivity after ap...

Induction heating is a typical application field for high-frequency power supplies whose operating frequencies range from one to several hundred kilohertz. Induction heating applies an alternating magnetic field generated from the current flow in a coil to the conductive matter to be heated. This induces eddy currents on the conductive matter, those currents generate joule loss due to the matte...

The purpose of this investigation was to obtain further information on the time-temperature relationships in the heat inactivation of bacteriophage strains active against Streptococcus lactis and Streptococcus cremoris and to determine whether the heat resistance characteristics of various bacteriophage strains were related to other criteria used in bacteriophage classification. Harriman, in hi...

The thermal shock resistance of ceramics depends on not only the mechanical and thermal properties of materials, but also the external constraint and thermal condition. So, in order to study the actual situation in its service process, a temperature-dependent thermal shock resistance model for ultra-high temperature ceramics considering the effects of the thermal environment and external constr...

The objective of this investigation was to characterize the mechanism of peripheral vasoconstriction observed in heart failure and to determine whether it can be attributed to the augmented sympathetic nervous activity, characteristic of this state. The response of the resistance bed in the forearm after release of inflow occlusion (reactive hyperemia), to hand exercise, and to local heating an...

It is well known that the heat resistance of bacterial spores is influenced markedly by the nature of the medium in which the spores are heated. This fact is an important problem relating to the practical sterilization in bacteriology and in the food industry. Hence voluminous data on the heat resistance of Clostridium botulinum and Clostridium porogenes in various kinds of foods or food juices...

We examined the effect of rate of temperature rise on the thermosensitivity of a murine lymphoblastic leukemia. L1210 cells suspended in RPMI 1630 medium:5% fetal bovine serum at pH 7.4 were heated from 37 degrees C-42 degrees C, or 44 degrees C over variable times (immediately, 30, 60, 120, 180 min) in a circulating water bath controlled by an electronic temperature programmer. Survival of the...

Three dimensional thermo-electrical analysis was employed to simulate the current density and temperature distributions for eutectic SnAg solder bumps with shrinkage bump sizes. It was found that the current crowdin...
