انواع تکینگی ها را برای فضا- زمان همگن و همسانگردی که با متریک فریدمن- روبرتسون - واکر توصیف می شود بررسی می کنیم. سپس به بررسی ویژگی تکینگی های آینده برای عالمی که انرژی تاریک از نوع فانتوم بر آن غالب است می پردازیم. نظریه گرانش (f(r به عنوان یک نظریه گرانش تصحیح یافته معرفی می شود که نسبیت عام اینشتین را تعمیم می دهد. قوانین اول و دوم ترمودینامیک برای افق ظاهری در این تئوری بررسی می گردند. اف...
background: understanding of cellular and molecular mechanisms involved in cell/tumor growth and progression has led to molecular-targeted therapy. her1 and her2 are two main oncogenic components of her-receptor family considered as targets for cancer research and therapy. reliable results of her- related research and targeted therapies dependent upon cell line with known her expression status....
the present paper is concerned with the structural characteristics and contents of the russian resistance poets from the outset up to the end of the world war ii, 1941-1945. regarding the linguistic and literary structures of the resistance poetry of this period, such features as changes in the lexical structure of poems, outspokenness, proximity of poetry to slogans can be easily observed. sem...
in order to achieve a sustainable management and development of natural resources, a set of technical, eco-social, environmental and ecological criteria must be considered in the planning process. an appropriate model is therefore needed to address all the criteria mentioned above, in the decision making process and finally provide a reliable result. in the last few years, analytical hierarchic...
the aim of this study was to determine the formulation of silver carp fish cracker and checking qualitative changes of cracker in the four time intervals (0, 30, 60 and 90 days), during storage at room temperature. treatments consisted of dried cracker (drying time 2 hours), cracker were fried (drying time 1 hour) and the final treatment was drought cracker that fried at the end of each period....
Let H be an infinite--dimensional Hilbert space and K(H) be the set of all compact operators on H. We will adopt spectral theorem for compact self-adjoint operators, to investigate of higher derivation and higher Jordan derivation on K(H) associated with the following cauchy-Jencen type functional equation 2f(frac{T+S}{2}+R)=f(T)+f(S)+2f(R) for all T,S,Rin K(H).
conclusions according to the high functionality of the produced recombinant vector, it seems a good applicable tool for making an indicator cell line in subsequent basic and drug studies. results recombinant vector, pgl4ltr-luc, has expression levels of more than 50 folds compared to the control when co-transfected with the tax expressing vector into hek 293t cells. moreover, cells display more...
