The Stellar Imf as a Property of Turbulence
We propose to interpret the stellar IMF as a property of the turbulence in the star–forming gas. Gravitationally unstable density enhancements in the turbulent flow collapse and form stars. Their mass distribution can be derived analytically from the power spectrum of the turbulent flow and the isothermal shock jump conditions in the magnetized gas. For a power spectrum index β = 1.74, consiste...
متن کاملtranslating allusive devices:a survey of a portrait of the artist as a young man by james joyce
تلمیح یکی از عناصری است که تقریباً در همه ی متون ادبی یافت و باعث ایجاد شکاف های فرهنگی می شود. در این تحقیق به عنوان شکلی از بینامتنیت در ترجمه مورد توجه قرار می گیرد. تلاش شده است تا راهکارهای مترجمان برای ترجمه چهار نوع اسامی خاص و عبارات کلیدی تلمیحی (مذهبی، سیاسی، تاریخی و اسطوره ای) موجود در رمانِ چهره مرد هنرمند در جوانی به فارسی بررسی شود. این تحقیق مقایسه ای بر اساس راهکارهای ترجمه تلمیح...
15 صفحه اولThe Statistics of Supersonic Isothermal Turbulence
We present results of large-scale three-dimensional simulations of supersonic Euler turbulence with the piecewise parabolic method (PPM) and multiple grid resolutions up to 20483 points. Our numerical experiments describe non-magnetized driven turbulent flows with an isothermal equation of state and an rms Mach number of 6. We discuss numerical resolution issues and demonstrate convergence, in ...
متن کاملthe significance of conjunction as a cohesive device in teaching writing
the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
15 صفحه اولSupersonic Turbulence in the Perseus Molecular Cloud
We compare the statistical properties of J=1→0 CO spectra observed in the Perseus Molecular Cloud with synthetic J=1→0 CO spectra, computed solving the non–LTE radiative transfer problem for a model cloud obtained as solutions of the three dimensional magneto–hydrodynamic (MHD) equations. The model cloud is a randomly forced super–Alfvénic and highly super–sonic turbulent isothermal flow. The p...
