abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
حوضه ی رسوبی کپه داغ در شمال و شمال شرقی ایران قرار گرفته و سازند خانگیران یکی از مهمترین سازندهای پالئوژن این حوضه میباشد. به منظور مطالعه این سازند ناودیس چهل کمان واقع در غرب شهر سرخس، شرق حوضه ی رسوبی کپه داغ انتخاب گردیده است. این سازند در برش مورد نظر دارای 136 متر ضخامت بوده و لیتولوژی آن شامل تناوبی از مارن به رنگ سبز زیتونی و مارن آهکی به رنگ زرد کرمی می باشد. مرز زیرین آن با سازند چهل...
Bright field imaging of biological samples stained with antibodies and/or special stains provides a rapid protocol for visualizing various macromolecules. However, this method of sample staining and imaging is rarely employed for direct quantitative analysis due to variations in sample fixations, ambiguities introduced by color composition and the limited dynamic range of imaging instruments. W...
We report Atacama Large Millimeter/submillimeter Array (ALMA) observations of polarized dust emission from the protostellar source Ser-emb 8 at a linear resolution of 140AU. Assuming models of dust-grain alignment hold, the observed polarization pattern gives a projected view of the magnetic field structure in this source. Contrary to expectations based on models of strongly magnetized star for...
A method to rapidly estimate the Fourier power spectrum of a point distribution is presented. This method relies on a Taylor expansion of the trigonometric functions. It yields the Fourier modes from a number of FFTs, which is controlled by the order N of the expansion and by the dimension D of the system. In three dimensions, for the practical value N = 3, the number of FFTs required is 20. We...
The initial conditions and relevant physics for the formation of the earliest galaxies are well specified in the concordance cosmology. Using ab initio cosmological Eulerian adaptive mesh refinement radiation hydrodynamical calculations, we discuss how very massive stars start the process of cosmological reionization. The models include non-equilibrium primordial gas chemistry and cooling proce...
this study was conducted to compare the methods of seed bedpreparation in rangelands of khash region in sistan and baluchestan province iniran. a split plot design was conducted based on randomized complete blockdesign with three replications in 1999. five seed bed preparation methods wereused as main plot as: 1) seed sown by passing livestock. 2) seed sown machinery.3) seeds sown as drilled in...
