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...

The age determination of latent fingerprint traces is a very important challenge for forensic investigations, which has not been solved satisfyingly so far. Based on prior work, we use the novel and very promising aging feature of counting binary pixel for the approximation of a mathematical aging function to be used for the age determination of latent fingerprint traces. We first show the feas...

This study examines the relationship pattern of the motivational climate,satisfaction of the psychological needs and self-determined motivation in youth male athletes based on the self-determination theory (Deci & Ryan, 1985, 2000). A sample of 255 athletes ranging from 12-14 years of age from varity of team sports completed the Motivational climate in youth sport, behavioral regulations toward...

A new method is presented to compute age estimates from theoretical isochrones using temperature, luminosity and metallicity data for individual stars. Based on Bayesian probability theory, this method avoids the systematic biases affecting simpler strategies, and provides reliable estimates of the age probability distribution function for late-type dwarfs. Basic assumptions about the a priori ...

Scale samples of Channa marulius were collected and studied for age determination and calculation of growth parameters. The fish were sampled from Harike Wetland during 1998 to 1999. Linear relationship with a high degree of correlation was observed between total fish length and the lateral scale radius. Age determination studies revealed 5 age groups. The harvestable size falls just below the ...
