in this letter, the numerical scheme of nonlinear volterra-fredholm integro-differential equations is proposed in a reproducing kernel hilbert space (rkhs). the method is constructed based on the reproducing kernel properties in which the initial condition of the problem is satised. the nonlinear terms are replaced by its taylor series. in this technique, the nonlinear volterra-fredholm integr...

background: control of the medium osmolarity and temperature during long or short time sperm manipulation is essential. objective: the objectives of the present study were to find the effects of different osmolarities of modified tyrode's solution and milk on the bull sperm during incubation at above zero temperatures. materials and methods: semen samples were collected twice from five najdi bu...

objectives the aim of this study was to evaluate the stability of antibacterial properties of nanosilver solution during a period of 9 months against streptococcus mutans, staphylococcus aureus and pseudomonas aeruginosa. materials and methods in this in vitro study, the antibacterial effect of serial concentrations of nanosilver solution and amoxicillin antibiotic as control group on the stand...

background: marital adjustment is one of the most extensive concepts to determine and show the happiness and stability rate of couples’ relationship. marital adjustment affects on different dimensions of individuals’ personal and social life. the purpose of this research is to study the effect of solution- focused short-term couple therapy on women’s marital adjustment increase in qom in 2012. ...

a new modified adomian decomposition method (adm) is utilized to obtain an analytical solution for buckling of the nanocantilever actuators immersed in liquid electrolytes. the nanoactuators in electrolytes are subject to different nonlinear forces including ionic concentration, van der waals, external voltage and electrochemical forces. the duan–rach modified adomian decomposition method is ut...

in this article, we apply two new fixed point theorems to investigate the existence of mild solutions for a nonlocal fractional cauchy problem with an integral initial condition in banach spaces.

sawdust is now being investigated as an adsorbent to remove contaminants from aqueous solution. heavy metals can be decreased very effectively with the organic material. in this research, adsorption of pb (ii) onto modified beech sawdust in a batch system was investigated. sawdust was collected from timber mill of qom, iran, and modified with h2so4 and naoh. then, the effects of various paramet...

lymph node dissection is of prime importance for accurate staging of colorectal carcinomas. since a great number of small lymph nodes are missed in the traditional method, several fat clearing solutions have been introduced for easier detection of smaller lymph nodes. in this study we evaluated the efficacy of a new fat clearing solution so-called lymph node revealing solution (lnrs) in colecto...

in this article, we apply the multiquadric radial basis function (rbf) interpo-lation method for nding the numerical approximation of traveling wave solu-tions of the kawahara equation. the scheme is based on the crank-nicolsonformulation for space derivative. the performance of the method is shown innumerical examples.

besides human dental and skeletal fluorosis, drinking water above permissible levels of fluoride is known to cause a wide range of adverse health effects. in this study, the adsorption of fluoride from aqueous solution onto pretreated zeolite has been studied by using batch test. the large surface area of natural zeolite (i. e., clinoptilolite from miyaneh region, iran) was utilized to create a...
