Micromachined resistors are thermal transducers that can be used to measure air and water flow rate. For the thermal resistor to function as a flow sensor, the electrical resistivity must be a strong function of temperature it must be sufficiently thermally isolated from the supports and substrate. The thermal resistor can be made of a metal or doped semiconductor and can thermally isolated by ...

We have studied the effect of temperature on transcription initiation in vitro at two related promoters ga/Pcon and ga/P1, which have the same nucleotide sequence around the -10 region and transcription start site, but differ in upstream sequences. One of the promoters, ga/Pcon, carries the consensus -35 hexamer, 5'TTGACA 3', whilst ga/P1 contains a block of 'distortable' upstream sequences tha...

Saxino decay can generate significant cosmological entropy, and hence dilute theoretical estimates of the present mass density of a given particle species. The dilution factor depends on the saxino and axion masses, and is constrained by the requirement that saxino decay should not affect nucleosynthesis, as well as by the usual requirement that the axion density be less than the critical densi...

Recent study shows that the nonuniform thermal distribution not only has an impact on the substrate but also interconnects. Hence, three–dimensional (3-D) thermal analysis is crucial to analyze these effects. In this paper, the authors present and develop an efficient 3-D transient thermal simulator based on the alternating direction implicit (ADI) method for temperature estimation in a 3-D env...

Most of the developing nations like Nigeria intend to develop in a sustainable manner. This development cannot be realized if refrigerated-based air conditioning systems that are characterized by high power requirement, high cost and with a negative influence on t he environment are used as a means of achieving thermal comfort in living spaces. Evaporative coolers are viable options of achievin...

Marble is a natural material, used in the construction field since antiquity. It has always been used to communicate monumentality and solidity. Nowadays new technologies permit marble to express new languages: particularly, translucent marble technology overturns the concept of solidity. The main issue to address is the lack of thermal-energy performance of such a thin stone layer as the only ...

An experiment was carried out at Faculty of Agriculture Department Agricultural Meteorology Farm, Centre for Advanced Meteorology, College Agriculture, Pune during Kharif seasons 2014 and 2015.The laid in split plot design with three replications.The treatment comprised brinjal hybrids viz.,V1:Phule Arjun, V2: Krishna, V3: Panchganaga as main four planting windows viz., P1: 31st MW (30 July-5 A...
