background: previous researches have shown that children with autism spectrum disorder and mental retardation have some dysfunctions in attention and inhibition functions. the present study evaluated the performance of attention and response inhibition in autism spectrum disorders, mental retardation and normal children. methods: the method of this study was ex post factor, so 15 children with...
Torsional tension in DNA may be both a prerequisite for the efficient initiation of transcription and a consequence of the transcription process itself with the generation of positive torsional tension in front of the RNA polymerase and negative torsional tension behind it. To examine torsional tension in specific regions of genomic DNA in vivo, we developed an assay using photoactivated psoral...
Many liquid storage tanks around the world have affected by earthquakes. This structure can store dangerous chemical liquids. Hence dynamic behavior of ground supported rectangular storage tanks is very important due to their applications in industrial facilities. In current research, the seismic behavior of two water storage rectangular concrete tanks is examined. For this purpose, these tanks...
Two-dimensional laser-induced fluorescence (2D-LIF) spectra are reported for a set of features in the S1 ↔ S0 electronic spectrum m-fluorotoluene. Two transitions previously assigned to fundamentals reassigned present work. The main reassignments confirmed with zero-electron-kinetic-energy (ZEKE) spectroscopy. Interactions S0, and D0+ states involving vibrational vibration-torsional (“vibtor”) ...
The study of surface waves in a layered media has their viable application in geophysical prospecting. This paper presents an analytical study on the dispersion of torsional surface wave in a pre-stressed heterogeneous layer sandwiched between a pre-stressed anisotropic porous semi-infinite medium and gravitating anisotropic porous half-space. The non-homogeneity within the intermediate layer a...
