fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
Background: Given that a significant part of deaths due to traffic accidents are preventable in the prehospital phase, so it seems necessary to have an instrument to identify and measure the factors affecting it. This study aimed to develop and psychometrically assess an instrument for measuring preventable prehospital mortality due to traffic accidents. Methods: The study is a mixed qualitati...
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...

A longitudinal qualitative design was used to capture views prior to and two weeks followin...
Rheology of the solid and melted cheese depends upon their functional properties. Farinograph is used for quality determination of wheat flour dough. Determination of the rheological properties of dough and dough like food materials from Farinograph is easy while study of cheese characteristics is very difficult and complicated. The present study is therefore designed for the possibility of qua...
