objective: the aim of the present study was to determine the prevalence of different psychiatric disorders among 12 to 17 years old adolescents in urban areas of tehran. method: in this study, 1105 adolescents (12 -17 years old) were selected from 250 clusters of the entire 22 municipality areas of tehran using a multistage sampling method. after responding to the farsi version of the strengths...

objective:  to evaluate the frequency of different psychiatric disorders among 7 to 12 years old children in urban areas of tehran. method: a sample of 799 children (6 to 11 years old) were selected from 250 clusters of the entire 22 municipality areas of tehran using a multistage sampling method from 250 clusters from the entire 22 municipality areas of tehran.. after responding to a persian v...

Hawking radiation remains a crucial theoretical prediction of semi-classical gravity and is considered one the critical tests for model quantum gravity. However, Hawking’s original derivation used field theory on fixed background. Efforts have been made to include space–time fluctuations arising from quantization dynamical degrees freedom itself study effects particles. Using analysis, we scala...

Using the monodromy method we calculate the asymptotic quasinormal (QN) frequencies of an electromagnetic field moving in D-dimensional Schwarzschild and Schwarzschild de Sitter (SdS) black holes (D ≥ 4). For theD-dimensional Schwarzschild anti-de Sitter (SadS) black hole we also compute these frequencies with a similar method. Moreover, we calculate the electromagnetic normal modes of the D-di...

Species abundance distributions (SADs) are widely used as a tool for summarizing ecological communities but may have different shapes, depending on the currency used to measure species importance. We develop a simple plotting method that links SADs in the alternative currencies of numerical abundance and biomass and is underpinned by testable predictions about how organisms occupy physical spac...

This paper describes the design of a high speed motion estimator using the Z-D log search algorithm. The architecture consists of 5 simple processing elements (PE) where each PE is capable of computing the sum-of-absolute-difference (SAD) to exploit the parallelism. For each step in the 2-D log search procedure, the 5 SADs of the 5 search points are computed in parallel. The design is implement...

Administration of psychostimulants is often associated with increased seizure susceptibility. In our previous studies prenatal methamphetamine (MA) exposure increased seizure susceptibility of adult rats in models of primarily or secondarily generalized seizures induced by convulsant drugs. The effect of a single MA challenge dose in adulthood on chemically induced generalized seizures however,...
