in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
BACKGROUND AND OBJECTIVES This study aimed to determine the accuracy of a diet quality measurement tool, the Total Diet Score (TDS) using two validation methods; firstly the TDS calculated from a food frequency questionnaire (FFQ) was compared to the TDS calculated from weighed food records (WFRs); secondly the TDS was compared to a number of dietary biomarkers. METHODS AND STUDY DESIGN Data ...
A parameter called TDS (Total Dermatoscopic Score), calculated by the wellknown ABCD formula, is frequently used in melanoma diagnosis. In our previous research we found a new formula, similar to the original ABCD formula, that yielded fewer diagnostic errors. This new ABCD formula was developed using data mining techniques, in particular, the rule induction algorithm LEM2, a part of the data m...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
The nervous system is main target of the toxic action of most of organic solvents. There is little doubt that occupational solvent exposure may result in persisting neurobehavioural disturbances--the organic solvent syndrome. Recently, the solvents are quoted among possible causes of the abnormal condition referred to as multiple chemical sensitivity (MCS), and which is characterized by a psych...
abstract this thesis includes five chapter : the first chapter assign to establish fuzzy mathematics requirement and introduction of liner programming in thesis. the second chapter we introduce a multilevel linear programming problems. the third chapter we proposed interactive fuzzy programming which consists of two phases , the study termination conditions of algorithm we show a satisfac...
BACKGROUND Testicular dysgenesis syndrome (TDS) is a common disease that links testicular germ cell cancer, cryptorchidism and some cases of hypospadias and male infertility with impaired development of the testis. The incidence of these disorders has increased over the last few decades, and testicular cancer now affects 1% of the Danish and Norwegian male population. METHODS To identify gene...
abstract: proverbs are of the language materials which of the food of any language depends on the quality and quantity of these same materials. in the present research, the researcher tried to present the ramsarian proverbs according to four variables of color, fruit, plantsand animals that selected from the book of the members of each of these four variables, put them into the spss system fo...
The film growth of the conjugated organic molecule rubicene on silicon dioxide was studied in detail. Since no structural data of the condensed material were available, we first produced high quality single crystals from solution and determined the crystal structure. This high purity material was used to prepare ultrathin films under ultrahigh vacuum conditions, by physical vapor deposition. Th...
SAM formation of undecanethiol (UDT) and mercaptoundecanoic acid (11-MUA) on Au(111) and on gold foils, using wet chemical preparation methods as well as physical vapor deposition (PVD) in UHV, has been studied by means of thermal desorption spectroscopy (TDS), low energy electron diffraction (LEED), and Auger electron spectroscopy (AES). The main aim of this study was to explore the possible a...
