in this paper the density and temperature dependencies of surface tension are investigated. using the lennard-jones (12,6), as an effective pair interaction potential, a linear expression is derived for isotherms of g /r2 versus r2 for some normal and chlorofluorocarbons (cfcs) fluids, where is surface tension and r = 1/v is molar density. the linearity behavior of the derived equation is wel...
کمپلکسی از pd(ii) با سولفوسالیسیلیک اسید(ssa) و اسیدآمینه والین(val) تهیه شد. فرمول کلی این کمپلکس k[pd(val)(ssa)] می باشد. این کمپلکس توسط آنالیز عنصری، هدایت مولی و طیف سنجی ft-ir ، uv-vis و 1h nmrشناسایی گردید. در این کمپلکس محلول در آب، لیگاند های آمینواسید والین و سولفوسالیسیلیک اسید به صورت دودندانه به مرکز پالادیوم متصل شده است. بخشی از بر همکنش کمپلکس با dna غده تیموس به وسیله طیف سنجی ...
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
In the present work, the interaction ofFe3O4@CaAl LDH@ Lamivudine with human serum albumin (HSA) was investigated by applying UV–vis and fluorescence spectra. The nanocomposite was quenching the natural fluorescence of HSA, which was indicated the static quenching mechanism. The consequences demonstrated that this nanocomposite can strongly bind to HSA molecules. According to fluorescence quenc...
We quantify the temperature-dependence of clear-sky climate sensitivity in a one-dimensional radiative-convective equilibrium model. The atmosphere is adjusted to fixed surface temperatures between 280 and 330 K while preserving other boundary conditions particular relative humidity CO2 concentration. show that an out-of-bounds usage radiation scheme rapid radiative transfer model for GCMs (RRT...
assume ? ? l2(rd) has fourier transform continuous at the origin, with ˆ ?(0) = 1, and thatcan be represented by an affine series f = j>0 k?zd c j,k?j,k for some coefficients satisfying c 1(2) = j>0 k?zd |c j,k|2 1/2 <?. here ?j,k(x) = |deta j |1/2?(a jx ?k) and the dilation matrices a j expand, for example a j = 2j i. the result improves an observation by daubechies that t...
For any $k in mathbb{N}$, the $k$-subdivision of graph $G$ is a simple graph $G^{frac{1}{k}}$, which is constructed by replacing each edge of $G$ with a path of length $k$. In [Moharram N. Iradmusa, On colorings of graph fractional powers, Discrete Math., (310) 2010, No. 10-11, 1551-1556] the $m$th power of the $n$-subdivision of $G$ has been introduced as a fractional power of $G$, denoted by ...
The structure of cholesterol above the (304.8 K) phase transition, previously published in preliminary form [Hsu & Nordman (1983). Science, 220, 604-606], has been fully refined using augmented X-ray data. The crystals are triclinic, space group P1, with (reassigned) cell parameters a = 27.565 (10), b = 38.624 (16), c = 10.748 (4) A, alpha = 93.49 (3), beta = 90.90 (3), gamma = 117.15 (3) degre...
