آنزیم گیاهی استریکتوسیدین سینتاز (ss) ، یک آنزیم کلیدی در بیوسنتز آلکالوئید گیاهی است. همولوگ دومین پروتئینی استریکتوسیدین سینتاز در ارگانیسمهای مختلفی یافت شده است. یک گروه چهارتایی از ژنهای شبه استریکتوسییدین سیینتاز در آرابیدوپسیس یافت شده اند که به سبب شباهت به همومیوسین، یک میوسین سطح سلولی دروزوفیلا با نام شبه همومیوسین (hml) نیز نامیده می شوند. در این آزمایش از ژنوتیپ های etr3، over ، hm...
Of the many hydraulic structures developed by man, the weir is perhaps the oldest. Weirs are used for the measurement of discharge and regulation of water flow. The most common types of weirs are broad-crested, sharp-crested, circular-crested and cylindrical, and ogee crest weirs. Advantage of the circular-crested and cylindrical weir compared to the other weirs include simplicity of design, st...
Shear wave velocity (Vs) is known as one of the fundamental material parameters which is useful in dynamic analysis. It is especially used to determine the dynamic shear modulus of the soil layers. Nowadays, several empirical equations have been presented to estimate the shear wave velocity based on the results from Standard Penetration Test (SPT) and soil type. Most of these equations result i...
OBJECTIVES To determine if echocardiographic measurements change at a greater rate in dogs with myxomatous mitral valve disease (MMVD) that die of cardiac mortality. ANIMALS Client-owned dogs (n = 242) with MMVD of varying severity were recruited from first opinion private practice. Only dogs which died during the study period (n = 102) were included in statistical analyses. METHODS Prospec...
throughout this dissertation r is a commutative ring with identity and m is a unitary r-module. in this dissertation we investigate submodules of multiplication , prufer and dedekind modules. we also stat the equivalent conditions for which is ring , wher l is a submodule of afaithful multiplication prufer module. we introduce the concept of integrally closed modules and show that faithful mu...
the flow of fluids in annular conduits has been studied for over sixty years, however the resulted data are very scattered. in this paper the problem is analytically solved, starting out with navier-stokes equations. a computer solution is used to determine the shape of velocity profiles, the discharge and the friction factor in a large number of concentric and eccentric annular conduits. the e...
The problem of two-phase MHD boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. The effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. The governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...
Two datasets of turbulence velocities collected over different bedform types under contrasting experimental conditions show similarity in terms of velocity-intermittency characteristics and suggest a universality to the velocity-intermittency structure for flow over bedforms. One dataset was obtained by sampling flow over static bedforms in different locations, and the other was based on a stat...
We extend the approach underlying the well-known Dix equation in reflection seismology to surface waves. Within the context of surface wave inversion, the Dix-type relation we derive for surface waves allows accurate depth profiles of shear-wave velocity to be constructed directly from phase velocity data, in contrast to perturbational methods. The depth profiles can subsequently be used as an ...
The objective of this research was to evaluate bromide leaching in a field under corn, wheat and alfalfa. Potassium bromide (300 kg/ha) was uniformly applied and 15 mm of water was sprinkled over the plots in the first and second years. Plots were leached 8 times during the first year and 9 times in the second year (each time with 100 mm of water). Soil samples were collected at 0-30, 30-60, 60...
