Statistical determination of bulk flow motions

the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...

Bulk Motions in Large-Scale Void Models

To explain the puzzling situation in the observed bulk flows on scales ∼ 150h Mpc (H0 = 100h −1 km sec Mpc), we consider the observational behavior of spherically symmetric inhomogeneous cosmological models, which consist of inner and outer homogeneous regions connected by a shell or an intermediate self-similar region. It is assumed that the present matter density parameter in the inner region...

Spectrophotometric Determination of Tropicamide in Bulk and Pharmaceutical Formulations

     A simple and sensitive extractive spectrophotometric method is described for determination of tropicamide. The method is based on the reaction of tropicamide and bromocresol green. The ion-paired colored complex was extracted with chloroform at pH 3. The extracted complex showed maximum absorbance at 423 nm. The complex was stable up to 2 days and obeyed Beer's law over the concentration r...

Dynamics of intracluster gas and bulk motions in clusters.

In this paper I briefly discuss progress in recent lines of research on the internal dynamics of clusters of galaxies that have been made possible thanks to improvements in current X-ray spectrometers that enable them to perform detailed spatially resolved spectroscopy. In particular, I focus on the study of bulk motion in intracluster gas and the nature of features called cold fronts.
