the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
Delineation of oxide and sulfide zones in mineral deposits, especially in gold deposits, is one of the most essential steps in an exploration project that has been traditionally carried out using the drilling results. Since in most mineral exploration projects there is a limited drilling dataset, application of geophysical data can reduce the error in delineation of the sulfide and oxide zones....
this thesis is presented 10 ghz voltage controlled ring oscillator for high speed application. the voltage controlled ring oscillator was designed and fabricated in 0.13یm cmos technology. the oscillator is 7-stages ring oscillator with one inverter replaced by nand-gate for shutting down in the ring oscillator during idle mode. tri-state inverter was used to control of 126 bit vector in ri...
Background: The genus lagochilus, family Lamiaceae consists of 44 species, 33 of which grow in central Asia. Only one report on the analysis of essential oil of Lagochilus species has been published. Objective: Aim of this study is to determine the chemical composition and antimicrobial activities of the hydrodistilled oil of flower and leaves of Lagochilus kotschyanus Boiss. of Iranian origi...
Hazardous Material transportation by road is coupled with inherent risk of accidents causing loss of lives, grievous injuries, property losses and environmental damages. The most common type of hazmat road accident happens to be the releases (78%) of hazardous substances, followed by fires (28%), explosions (14%) and vapour/ gas clouds (6 %.). The paper is discussing initially the probable ‘Imp...
also tested. 4-Nitroquinoline 1-oxide, 4-hydroxyaminoquinoline 1oxide, 3-methyl-4-nitropyridine 1-oxide, and 2,3-dimethyl-4nitropyridine 1-oxide caused wider growth-inhibiting zones with mutants of Escherichia coli, such as the DNA polymerase 1-deficient mutant, po/Al, and the recombination-deficient mutants, r<?cA13 and recB21, than with the wild strain. These compounds also caused wider growt...

Marine benthic macrophytes (seaweed and seagrasses) are key structural and functional components of some of the most productive ecosystems of the world. They absorb nutrients through their surface directly from the marine environment and thus they are very important biological elements for the estimation of ecological status, representing reliable indicators of coastal waters. The aim of this s...
the volatile oil obtained by hydrodistillation of the aerial parts of matricaria chamomilla l. (asteraceae) growing in botanical garden, isfahan university of medical sciences, iran, was investigated by gas chromatography (gc) and gc/ mass spectrometery (ms). sixty-three components were characterized, representing 86.21% of the total oil components detected. α-bisabolol oxide a (25.01%) and a-b...
