Introduction: Prostate specific antigen (PSA) is one of the most sensitive markers for diagnosis of prostate cancer. Immunoradiometric kit (IRMA) is a common and sensitive method for determination of PSA in clinical laboratories. This kit has four major components: solid phase coated with monocolonal antibody, pair antibody labelled with I-125, series of standards i...

the sensitivity analysis for multi-attribute decision making (madm) problems is important for two reasons: first, the decision matrix as the source of the results of a decision problem is inaccurate because it sorts the alternatives in each criterion inaccurately. second, the decision maker may change his opinions in a time period because of changes in the importance of the criteria and in the ...

The nanocomposites of polythiophene and carboxylated multiwalled carbon nanotubes (MWCNTs) were synthesized by in-situ chemical oxidative polymerization method using anhydrous ferric chloride (FeCl3) as an oxidant. The MWCNTs functionalized and ultrasonicated to obtain uniform dispersion within the polythiophene matrix. Field emission scanning electron microscopy was used to characterize the mo...
