We present the power spectrum of solar irradiance during 1985 and 1987 obtained from the ACRIM project from time scales of minutes to months. At low frequency the spectra are Lorentzian (proportional to 1/(f 2 + f 2 o )). At higher frequencies they are proportional to f 1 2 . A linear, stochastic model of the turbulent heat transfer between the granulation layer (modeled as a homogeneous thin l...

The rocky intertidal zone is among the most physically harsh environments on earth. Marine invertebrates and algae living in this habitat are alternatively pounded by waves and exposed to thermal extremes during low tide periods (Denny and Wethey, 2001). Additionally, they must deal with strong selective pressures related to predation and competition for space (Connell, 1961). As a result, the ...

The Mahin area is a part of TaromHashtjin zone that located in west of Qazvin province in northwest of Iran. Many copper and base metals ore deposits are hosted by this zone. High potential localities identification in this area is very necessary. The objective of this research, is finding hydrothermal alteration zones by remote sensing methods and best processing technique of Advanced Spacebor...

abstract sunflower is one of the most important oilseeds in the world which has adaptation to high temperature. however, its cultivation in many different areas is neither desirable nor economical. considering that sunflower is a crop that is irrigated by adequate river water in the province of isfahan, temperature is a determining role in the final revenue. appropriate temperatures are shown a...

The primary inversion of the accurately measured frequencies of solar oscillations determines the mechanical properties of the Sun, i.e., the sound speed and density as a function of solar radius. In order to infer the temperature and hydrogen abundance profiles inside the Sun, it becomes necessary to use, in addition, the equations of thermal equilibrium along with the input physics, such as o...

Chemical maps of garnet are the key to understand the tectonometamorphic evolution of the metamorphic rocks. They provide useful information on element distribution, diffusion, and mechanical truncation of crystal. In the Himalayas, studies on ultra-high pressure rocks denudated along the Main Central Thrust (MCT) revealed the great displacement along this intracontinental shear zone. Pêcher (1...
