abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
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)</...
Gas chromatographic methods using solvent extraction for the analysis of cyclopropane and and trichloroethene (trichloroethylene) are described and evaluated; cyclopropane was extracted into carbon tetrachloride and trichloroethene into carbon disulphide, using chloroform and toluene respectively as the internal standards. Ostwald solubility coefficients were measured for cyclopropane, halothan...
The ceramic sample of La1 ·4Sr1 ·6Mn2O7 ·06 exhibits the metal–insulator transition and a negative magnetoresistance in the vicinity of the Curie temperature (TC ' 100 K). The dc magnetic susceptibility between 100 K and 280 K is nearly constant and decreases gradually with increasing temperature above 280 K. The measurements of dc resistivity and the thermoelectric power indicate that small po...
در این پایان نامه برهمکنش دو کمپلکس ضدتومور پالادیم با فرمول [pd(phen)(mor-dtc)]no3 (که در آن phen = 1،10- فنانترولین و mor-dtc = مورفولین دی تیوکربامات می باشد) و [pd(phen)(pip-dtc)]no3 (که در آن pip-dtc = پی پیریدین دی تیوکربامات می باشد) با dna تیموس گوساله به روش تیتراسیون همدما به کمک طیف سنجی uv–visible در محیط تریس بافر (25mmol/l) و ph= 7.0 در دو دمای 300 و 310 کلوین انجام شد. در این م...
Temperature and intensity dependence of steady state photoconductivity is studied in amorphous thin films of Ge22Se68Bi10 prepared by vacuum evaporation. Photoconductivity increases exponentially with temperature between 310 K and 410 K and no maxima is found in this temperature range. The ratio Iph/Id is about 6 at 310 K and decreases continuously as temperature is increased. Photoconductivity...
the potassium pools of five major physiographic units of urmia region in western azarbaijan province were studied to investigate the distribution of k forms as a function of clay mineralogy and physiographic units. for this, soil samples from different horizons of ten pedons were selected and analyzed for physiochemical properties, mineralogy of clay fraction, and forms of k. analyses of xrd re...
A model has been used to simulate potassium (K) uptake by wheat in a pot culture experiment. Three soils from India, namely Alfisol, Inceptisol and Vertisol, were differentially K exhausted by Sudan grass (Surghum vulgare var. Sudanensis) for a period of 280 days and were used to simulate potassium uptake by wheat (Triticum aestivum) and also to predict the amounts of K released or fixed during...
To investigate the mechanism of structural changes of a peptide nanotube and water confined inside the channel, the helical peptide tryptophylglycine monohydrate (WG.H2O) was studied by molecular dynamics (MD) simulations using the three-dimension parallel MD program ddgmq (software package) and a consistent force field. Simulations were performed on both the water-containing system and a model...
در این پایان نامه روش های ارائه شده توسط هررو1 و تم2 در سال 2011 در مقاله ای با عنوان using the gsvd and the lifthing technique to find {p,k+1} reflexive and anti-reflexive solutions of axb=c برای پیدا کردن جواب های انعکاسی و پاد-انعکاسی {p,k+?} معادله ماتریسی axb=c بیان شده اند را بررسی می کنیم. در پایان از این روش ها برای پیدا کردن جواب های {p,?k} انعکاسی معادله ی ماتریسی axb+cx^* e=f استف...
