فرض کنیم g یک گروه توپولوژیک با همانی e باشد و a(g)?l^? (g). زیر مجموعه ی t?g را (الف)مجموعه ی درونیاب a(g). می نامیم اگر تابع کران دار f:t?c را بتوان به تابع f ?:t?c توسیع داد به طوری که f ??.a(g) ؛ (ب) مجموعه ی درونیاب تقریب پذیر a(g)می نامیم اگر مجموعه ی درونیاب a(g). باشد و برای هر همسایگی u از e، همسایگی های باز v_1 و v_2 از e با شرط v ?_1?v_2?u وجود داشته باشند به طوری که برای هر t_1?t...
evaluation of river discharges trends is very important for water resources management and design of irrigation and drainage networks. in this research, annual, seasonal and monthly trends of maroon river discharge were evaluated using the mann-kendall and senâs slope estimator non-parametric tests and the regression analysis parametric test. for this purpose, river discharge data from five h...
in this study, al/gr composites with 5,10,15,20 weight percent of graphite were produced by in-situ powder metallurgy method. the produced powder mixtures were consolidated and sintered at optimum conditions. the resultant composites were solution treated at 495?c and aged at 170?c. the influence of graphite content on the bending strength of composites was studied. the distribution of graphite...

the aim of this study was to investigate the hemagglutination properties of caprine herpesvirus-1(cphv-1) and their application for cphv-1 antigen detection and evaluation of the dynamics of postinfectious/vaccine antibody production. cphv-1 hemagglutination activity was proved only with mouseerythrocytes, pbs and saline solutions at 4°c and 22°c. in vaccinated animals, goats and bucks withresp...
in most of the sugar beet cultivated areas including kermanshah, iran, late season irrigation is cut- off earlier than usual which causes drought stress in the crop. since root yield still increses in sept. and oct. these areas, withholding irrigation in this period reduce root yield and quality of sugar beet. for this reason, an experimente was conducted during 2004- 2005 based on split plot d...
in this paper, lift and drag coefficients were numerically investigated using numeca software in a set of 4-digit naca airfoils. two metamodels based on the evolved group method of data handling (gmdh) type neural networks were then obtained for modeling both lift coefficient (cl) and drag coefficient (cd) with respect to the geometrical design parameters. after using such obtained polynomial n...
background: objective: methods: results: discussion:
the effect of arbuscular mycorrhizal fungi and plant growth promoting rhizobacteria, with the ability to produce acc deaminase enzyme, on water relationships and agronomic indices of sunflower (helianthus annuus l.) cultivars was investigated. the soil used was of an ec equal to 7.6 ds m-1. a greenhouse factorial experiment on the basis of a completely randomized block design with three levels ...
chapters 1 and 2 establish the basic theory of amenability of topological groups and amenability of banach algebras. also we prove that. if g is a topological group, then r (wluc (g)) (resp. r (luc (g))) if and only if there exists a mean m on wluc (g) (resp. luc (g)) such that for every wluc (g) (resp. every luc (g)) and every element d of a dense subset d od g, m (r)m (f) holds. chapter 3 inv...
