the aim of this work is to examine the feasibilities of the support vector machines (svms) and k-nearest neighbor (k-nn) classifier methods for the classification of an aquifer in the khuzestan province, iran. for this purpose, 17 groundwater quality variables including ec, tds, turbidity, ph, total hardness, ca, mg, total alkalinity, sulfate, nitrate, nitrite, fluoride, phosphate, fe, mn, cu, ...

Background and Objectives: For total analytical error, imprecision (SD) and bias, performance goals for laboratory tests have most often been developed. A total analytical error goal requires that the combination of errors from all sources (random and systematic errors) be within some acceptable limit. M...

background and objectives: for total analytical error, imprecision (sd) and bias, performance goals for laboratory tests have most often been developed. a total analytical error goal requires that the combination of errors from all sources (random and systematic errors) be within some acceptable limit. materials and methods: fifty vials of sodium and potassium standards (sandos company) were ch...

introduction: this study was carried out to compare the capability of k-files with mtwo rotary file in terms of negotiation as well as depth of penetration in second mesiobuccal (mb2) canal of maxillary first molar. materials and methods: a total of 32 mb2 canal of maxillary first molars having different root curvatures (not more than 30 degree) and root lengths were selected and then detected ...

conclusions the results indicate that the rates of esbls are high in urine e. coli and k. pneumoniae isolates from tehran hospitals. also this study indicates that the urine isolates from male patients are significantly more resistant than the female isolates. materials and methods a total of 190 e. coli and k. pneumoniae isolates were collected from patients’ urine samples in hospitals from te...

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...

In this study some selected chemical properties such as total soluble solids, pH, total acidity, formalin index,  reduced sugar content and ascorbic acid of major sour cherry cultivated grown in different provinces of Iran corresponding were investigated.  Minerals K+, Na+, Ca2+, Mg2+, Cu2+, Fe2+ and Zn2+ were determined by graphite furnace atomic absorption spectrophotometer. The result showed...

the purpose of this work was to develop once daily sustained release (sr) matrix tablets of naproxen, an anti-inflammatory agent. the tablets were prepared by wet granulation method along with hydrophilic matrix materials like methocel k 15m cr and methocel k 100m cr. the granules were evaluated for bulk density, angle of repose, compressibility index, total porosity and drug content. the table...
