An ECRF program has been started to study the local heating and current drive in JT-60U. The frequency of 110GHz was adopted to couple the fundamental O-mode from low field side with an oblique toroidal injection angle for current drive. Experiments were performed at the injection power of ~1.5 MW by using three gyrotrons, each of which has generated the output power up to ~0.8 MW for 3 seconds...

Meteorological mechanisms affecting the evolution of a persistent wintertime cold air pool that began on 2 January and ended on 7 January 1999 in the Columbia basin of eastern Washington were investigated using a mesoscale numerical model together with limited observations. The mechanisms include surface radiative cooling and heating, large-scale subsidence, temperature advection, downslope war...

A study was undertaken to characterize surface temperatures of mounds of imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae) and S. richteri Forel, and their hybrid, as it relates to sun position and shape of the mounds, to better understand factors that affect absorption of solar radiation by the nest mound and to test feasibility of using thermal infrared imagery to remotely...

Abstract Reconstructing the history of polar temperature from ice core water isotope ( ? 18 O) calibration has remained a challenge in paleoclimate research, because our incomplete understanding various temperature– O relationships. This paper resolves this classical problem new framework called unified slope equations (USE), which illustrates general relations among spatial and temporal O–surf...

invert sugar is the result of sucrose of hydrolysis of sucrose by acid or enzyme, that is, the splitting of sucrose molecules into their glucose and fructose components.invert sugar is used in different industries such as; food industry, soft drinks and pharmaceutical, due to its special characteristics such as; sweetness level, moisture ability’s property, crystallization level and special tas...

Tunneling two-level systems (TLSs) are believed to be the source of phenomena such as the universal low temperature properties in disordered and amorphous solids, and 1/f noise. The existence of these phenomena in a large variety of dissimilar physical systems testifies for the universal nature of the TLSs, which however, is not yet known. Following a recent suggestion that attributes the low t...

The applicability of heat clearance for assessments of regional myocardial blood flow was examined in dogs. The axial and radial temperature field around the heated junction of the cross-thermocouples, sewn into the subepicardial layers of normally beating left ventricle of open-chest dog, was about 3.5mm. The heated tissue volume was approximately 0.31ml. The blood outflow from the cylinder in...

high intensity optical radiation can cause damage to the eye and intense radiation in the range of 770-1400 nm can cause thermal retinal damage. in the workplaces where there are high temperature sources, the workers in front of these hot  sources without bright light maybe exposed to the  intense ir radiation, thus regular measurement of these radiations seems crucial. measurement of ir radiat...
