Thus P' represents the maximum value of the spectral absorption coefficient if only Doppler broadening occurred; b, bc, and bD denote, respectively, the natural half-width,t the half-width resulting from collision (Lorentz) broadening, and the half-width produced by Doppler broadening; S is the integrated intensity of the spectral line under study whose center lies at wo; m is the mass of the r...
The lifetime of the stretch mode of bond-center hydrogen in crystalline silicon is measured to be T1 = 7.8+/-0.2 ps with time-resolved, transient bleaching spectroscopy. The low-temperature spectral width of the absorption line due to the stretch mode converges towards its natural width for decreasing hydrogen concentration C(H), and nearly coincides with the natural width for C(H) approximatel...
فرض کنید $ r $ و $ s $ دو حلقه و $ {}_sc_r $ یک دو مدول شبه دوگان باشد. در این پایان نامه ما رابطه ی بین $ g_{c} $-مرابطه با $ c $-مرابطه و هم چنین رابطه ی بین تحلیل $ g_{c} $-تصویری و تحلیل تصویری از یک مدول را بررسی می کنیم. به علاوه نشان می دهیم که اگر egin{center} $ mathbf{g}^{ullet} : cdots ightarrow g_{1} ightarrow g_{0} ightarrow g^{0} ightarrow g^{1} ightarrow cdots$ end{center}...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
We construct a polynomial-time algorithm to approximate the branch-width of certain symmetric submodular functions, and give two applications. The first is to graph “clique-width”. Clique-width is a measure of the difficulty of decomposing a graph in a kind of tree-structure, and if a graph has clique-width at most k then the corresponding decomposition of the graph is called a “k-expression”. ...
of the Caucasian population. The purpose of this study was to investigate the morphometry of the proximal tibia in thestandard resected surface of total knee arthroplasty (TKA).Methods: In this descriptive study, the anthropometric data of the proximal tibia were measured in 132 knees (80 malesand 52 females) using magnetic resonance imaging in 2015. The collected data include...
Coupling between adjacent Finite Ground Coplanar (FGC) waveguides as a function of the line geometry is presented for the first time. A two Dimension-Finite Difference Time Domain (2D-FDTD) analysis and measurements are used to show that the coupling decreases as the line to line separation and the ground plane width increases. Furthermore, it is shown that for a given spacing between the cente...
Objectives: The survey was designed to identify which pathways psychiatric patient go through in seeking psychiatric services, how often they visit general physicians, other specialists, health care centers, and traditional healers, whether they use herbal medicine, and how they refer to Imam Hussein General Hospital Psychiatric Training Center. Method: 256 Patients (109 female and 146 male) wh...
this study was carried out in order to determine the leave characteristics of some chestnut genotypes in the central black sea region of turkey and also to determine whether the leaf morphometric characteristics could be used for differentiation of genotypes. in this study, seven chestnut (castanea sativa mill.) genotypes (sa5-1, se 3-12, se 21-2, se 21-9, 552-8, 556-7 and 556-8) and one cultiv...
in order to evaluate genetic diversity among squash landraces from northwest iran by morphological and physiological traits, 18 squash landraces belong to pumpkin, ornamental and confectionary groups were planted in completely randomized block design with three replications in agricultural research center of urmia in 2013. morphological characteristics related of fruit, seed, leave and flower a...
