The lack of evidence for the existence of extraterrestrial life, even the simplest forms of animal life, makes it is difficult to decide whether the search for extraterrestrial intelligence (SETI) is more a high-risk, high-payoff endeavor than a futile attempt. Here we insist that even if extraterrestrial civilizations do exist and communicate, the likelihood of detecting their signals cruciall...
A stochastic radiative transfer equation for the mean l( → X), cosine of polar angle of direction → X d( → X2 → X0), Dirac delta function field and its solution for the case of discontinuous vegetation canopies is discussed in this article. The equation set v(→r ), indicator function Fdir(k), extraterrestrial solar radiance at the top of satisfies the law of energy conservation and is amenable ...
The development of new reference evapotranspiration (ETo) methods hold significant promise for improving our quantitative understanding of climatic impacts on water loss from the land to the atmosphere. To address the challenge of estimating ETo in tropical and subtropical regions where direct measurements are scarce we tested a new method based on geographical patterns of extraterrestrial radi...
I N T H E E F F O R T of devising ways and means of studying the existence of living organisms on other planets, attention must be focussed on microorganisms. This is not entirely due to professi,onal prejudice of microbiology, but is the consequence of accepted realization that microorganisms are responsible for the major amount of turnover of matter on earth and that life of the higher plants...
Agrometeorological stations have horizontal solar irradiation data available, but the design and simulation of photovoltaic (PV) systems require about panel (inclined and/or oriented). Greenhouses for agricultural production, outside large protected production areas, are usually off-grid; thus, variable on plane is critical an optimal PV design. Modeling radiation components (beam, diffuse, gro...
IceCube, a cubic kilometer detector at the South Pole, is the largest neutrino telescope currently taking data. Utilizing the transparent ice of Antarctica as a detection medium, IceCube digital optical sensors observe Cherenkov radiation from secondary particles produced in neutrino interactions inside or near the detector. Charged current nμ interactions create muon tracks, while charged curr...
background: the aim of the present study was to evaluate the radioprotective effect of grewia asiatica fruit pulp extract (gae) on swiss albino mice exposed to gamma radiation. in the present study radioprotective efficacy of grewia asiatica (rich in anthocyanin, carotenes, vitamin c, etc.) was studied against radiation induced biochemical alterations in mice cerebrum. materials and methods: fo...
The Open University's repository of research publications and other research outputs The combustion characteristics and stable carbon isotopic compositions of irradiated organic matter: implications for terrestrial and extraterrestrial sample analysis Conference Item (2005). The combustion characteristics and stable carbon isotopic compositions of irradiated organic matter: implications for ter...
