After lightning, precipitation formed, these lightning phenomena occur in the atmosphere by high power laser pulse. After striking the laser pulse, condensation and water drop formation take place in the atmosphere. It is well known that, for water drop formation, condensation must occurred (condensation is the basic need for water drops formation).Condensation means, heat energy subtraction. H...

"Ageing in place" is a policy initiative strongly advocated by the World Health Organization to face the challenge of an ageing population. This pilot study used a "photovoice" approach, aiming to explore aspects of the housing environment considered by older people as important in facilitating ageing in place. It enabled participants to express their ideas through photographs. Each participant...

The production of antifungal substances by bacteria has long been recognized and this knowledge is entering practical life through the use of bacterial antagonists to protect crops against their fungal enemies. Recently, it has become clear that in addition to diffusible substances, bacteria emit a wide range of volatile compounds into the atmosphere. Over the last ten years, evidence has accum...

As architects and designers we have a responsibility to provide an inclusive built environment. For the Autistic Spectrum Disorder (ASD) sufferer however, the built environment can be a frightening and confusing place, difficult to negotiate and tolerate. The challenge of integrating more fully into society is denied by an alienating built environment. For ASD pupils in a poorly designed classr...

With the growing levels of green house gases in the atmosphere, many people have shown increased interests to embrace the environmental-friendly mode of transportation, biking [5]. Incidentally, biking offers numerous other benefits, such as a means of daily exercise while commuting to work, which is both economical and saves time. Montana State University (MSU) strives to be one of the leaders...

things. There was no flora, no fauna; the Earth was completely barren of life. Instead of having an atmosphere rich in nitrogen and oxygen as it is today, the atmosphere on primitive Earth was composed primarily of methane, ammonia, hydrogen gas and water vapor. The lack of a protective ozone layer resulted inhigh exposure to UV light and radiation. Earth was also extremely volcanically active ...

TA(ν) has little to do with the radiation temperature of the source, which is not restricted to have a thermal spectrum. It is more accurately a noise temperature. If one were to place a telescope or feed and detector with small bandwidth ∆ν above the atmosphere and measure power Pν , one could replace that whole system with a resistor at temperature TA(ν), and measure the same power. Similarly...

We review the main factors driving the calculation of the tangent height of spaceborne limb measurements: the ray-tracing method, the refractive index model and the assumed atmosphere. We find that commonly used ray tracing and refraction models are very accurate, at least in the midinfrared. The factor with largest effect in the tangent height calculation is the assumed atmosphere. Using a cli...

the cross-coupling reaction between phenylboronic acid and various types of aryl halides (suzuki reaction) was carried out using a catalytic amount of a new palladium catalyst (1-benzyl-3-(1-benzyl-1-methylpyrrolidin-1-ium-2-yl) pyridin-1-ium palladium chloride [dbnt][pdcl4]) in poly (ethylene glycol) (peg-200) in the presence of koh as the base. this new catalyst was synthesized and characteri...
