We report the development of a novel method to determine the thermopower of atomic-sized gold contacts at low temperature. For these measurements a mechanically controllable break junction (MCBJ) system is used and a laser source generates a temperature difference of a few kelvins across the junction to create a thermo-voltage. Since the temperature difference enters directly into the Seebeck c...

Normalized difference vegetation index and land surface temperature data, in a sample plot each from east, center and west of Nepal, from 2000 to 2015, were analyzed to identify and compare the trends of vegetation and temperature changes during the period. The data were obtained from moderate resolutions imaging spectro-radiometer. Normalized difference vegetation index charactiszes a resoluti...

The objective of this study is to design and analyse materials which are capable of harvesting water from thin air using condensation phenomenon which employs the radiative cooling approach. These passive cooling materials not only solve the water generating problems, but also employed in various cooling applications. The fundamental concept of radiative cooling is analysed and the performance ...

because of importance of morphological characteristics, canopy temperature and their relationship with grain yield in rice varieties, an experiment was conducted based on split plot in a randomized complete block design with three replications in two years (2013-2014) at the college of agriculture, university of guilan. the experiment consisted of three transplanting times (5, 20 may and 5 june...

Remote sensing data in the thermal infra red (TIR) part of the spectrum provides indirect estimates of water stress – defined as a function of the ratio between actual and potential evaporation rates – at the earth surface. During the first stage of evaporation (‘‘energy limited’’ evaporation), this ratio is close to one. During the second stage of evaporation (‘‘soil controlled’’ evaporation) ...

PURPOSE To determine whether brain temperature measured by using preoperative proton magnetic resonance (MR) spectroscopy could help identify patients at risk for cerebral hyperperfusion after carotid endarterectomy (CEA). MATERIALS AND METHODS Institutional review board approval and informed consent were obtained. Acquisition of proton MR spectroscopic data by using point-resolved spectrosco...

(6) There was. no material difference in temperature between a depth of 6 inches and one of 7 inches, while there was a distinct difference of temperature between a depth of 4 inches and one of 6 inches, thus showing the unreliability of measurements of temperature at a depth of less than 6 inches. (7) The standing as compared with the lying position of the animal had hardly any effect on the b...

OBJECTIVES A nondestructive, rapid, and practical method of dental alloy sorting is desirable. In this study, the hypothesis to be tested is that dental alloys show significantly different and high thermoelectric power values, on the basis of which alloy sorting is possible. METHODS Six silver-colored commercial dental casting alloys are used in this study: two silver alloys, one gold-silver-...

We developed a novel temperature measurement and control method that uses color analysis of fluorescence spectrum. Functional gel-tools encapsulating quantum dots (Q-dots) was used. These tools can be manipulated in a solution by optical tweezers. We used color analysis of the fluorescence for temperature measurement. YCrCb information (Y: brightness, Cr: red color difference, Cb: blue color di...

this paper modeled heating air of a room through examining free convection in a 3d chamber. the chamber had cold and hot sources with tc and th temperatures, respectively. its other walls were adiabatic. this study aimed at predicting effect of temperature difference, displacement of hot and cold sources and their aspect ratio on flow field, temperature and heat transfer rate. to conduct the st...
