Cooling reduces the ischemia/reperfusion (I/R) injury seen in sudden cardiac arrest (SCA) by decreasing the burst of reactive oxygen species (ROS). Its cardioprotection is diminished when delay in reaching the target temperature occurs. Baicalein, a flavonoid derived from the root of ScutellariabaicalensisGeorgi, possesses antioxidant properties. Therefore, we hypothesized that baicalein can re...

In canine cutaneous veins, cooling augments the contractile responses evoked by sympathetic nerve stimulation despite a cooling-induced reduction in the release of norepinephrine. With exogenous norepinephrine, the increased responsiveness observed during cooling results from enhanced sensitivity of the postjunctional alpha-2 adrenoceptors. The present experiments were performed to analyze the ...

A new classification of neutron star cooling scenarios, involving either “minimal” cooling or “enhanced” cooling is proposed. The minimal cooling scenario replaces and extends the so-called standard cooling scenario to include neutrino emission from the Cooper pair breaking and formation process. This emission dominates that due to the modified Urca process for temperatures close to the critica...

The broadband SEDs of blazars exhibit two broad spectral components which in leptonic emission models are attributed to synchrotron radiation and SSC radiation of relativistic electrons. During high state phases the highfrequency SSC component often dominates over the low-frequency synchrotron component implying that the inverse Compton SSC losses of electrons are at least equal to or greater t...

Nowadays, ever-increasing energy demands and the depletion of fossil fuels require efficient environmentally friendly technologies for generation. In this context, systems integration makes a very strong proposition since it results in saving, fuel diversification, supply cleaner energy. To end, is utmost importance to realize current developments field portray state art renewable generation in...

A systematic study of factors affecting the delamination energy release rate and mode mix of a thermal barrier coating attached to a substrate is presented accounting for the influence of thermal gradients combined with rapid hot surface cooling. Transient thermal gradients induce stress gradients through the coating and substrate, which produce overall bending if the substrate is not very thic...

BACKGROUND AND PURPOSE Localized head and neck cooling might be suited to induce therapeutic hypothermia in acute brain injury such as stroke. Safety issues of head and neck cooling are undetermined and may include cardiovascular autonomic side effects that were identified in this study. METHODS Ten healthy men (age 35±13 years) underwent 120 minutes of combined head and neck cooling (Sovika,...

Recently interest in adsorption cooling systems has increased due to their capability to utilise low grade heat sources and environmentally friendly refrigerants. Currently, most of the commercially available adsorption cooling systems utilise granular packed adsorbent beds. Enhancing the heat transfer process inside the adsorbent bed will improve the overall efficiency of the adsorption system...

Microchannel liquid cooling is a promising technique to handling the high temperature problem of threedimensional (3D) processors. There have been a few works which made initial attempts to optimize liquid cooling by utilizing non-uniformly distributed channels, variable flow rate, wider channels, and Dynamic Voltage and Frequency Scaling (DVFS) combined with thread migration mechanisms. Althou...
