We test the hypothesis that the starless cores may be gravitationally bound clouds supported largely by thermal pressure by comparing observed molecular line spectra to theoretical spectra produced by a simulation that includes hydrodynamics, radiative cooling, variable molecular abundance, and radiative transfer in a simple one-dimensional model. The results suggest that the starless cores can...

Theories of the meaning of life are divided into two categories: nihilistic and anti-nihilistic. The latter is divided, in turn, into the view that life is meaningful and the view that life can be made meaningful. In this paper, we deploy a descriptive-analytic method to discuss Jean-Paul Sartre’s view of nihilism. In his view, God does not exist, the human being is born and dies without a reas...

in the early years, the rising of the sea level, which is a part of natural treatment, destroyed many buildings, arable lands, residential and commercial areas. it seems that the main reason of these destructions is the diminishing of the legal setback efficiency and the proceeding of human activities. the aim of this study is to introduce the appropriate setback for southern coast of caspian s...

Atherosclerosis has serious role in coronary arteries disease,so it is important to establish effective strategies for prevention or even treatment of atherosclerosis. Adiponectin, as one of the most abundant adipokines, has insulin sensitivity, anti-inflammatory and anti-atherogenic properties. Disturbed adiponectin actions through its receptor, (AdipoR1 and AdipoR2) may be involved in atheros...
