This article analyses the religious sub-cultures of youth who live in Mashhad. The main question of this research is about youth classification and their beliefs, values and norms. Statistical population is chosen from the youth who are 15 to 29 years old and 600 persons are regarded as the sample study. In the research method is survey and data gathering instrument is aresearcher-made question...

Phonological awareness skills are critical for reading acquisition, yet relatively little is known about the origins of phonological awareness. This study investigates one plausible source of the emergence of phonological awareness, phonological neighbourhood density. As vocabulary grows, the number of similar-sounding words in the child's mental lexicon increases. This could create development...

The recently described THAP domain motif characterizes a DNA-binding domain (DBD) that is widely conserved in human and in animals. It presents a similarity with the DBD of the P element transposase of D. melanogaster. We show here that the P Drosophila neogenes derived from P-transposable elements conserve the THAP domain. Moreover, secondary rearrangements by exon shuffling indicate the recur...

We have previously shown that ethanol or chloroform extracts of the leaves of Impatiens balsamina (LIB) have anti-tumor activity against the human hepatocellular carcinoma cell line HepG2. The ethanol extracts were separated into five fractions according to polarity. An MTT assay indicated that two of the fractions had anti-tumor activity and that the petroleum ether fraction (PEF) was the most...

Abstract This study presents petrographic and geochemical characterization of 46 pre-impact rocks 32 impactites containing and/or representing impact melt rock from the peak ring Chicxulub structure (Yucatán, Mexico). The aims were both to investigate components that potentially contributed (i.e., lithologies) better elucidate emplacement at Chicxulub. presented here are subdivided into two sam...

it is necessary to use empirical models for estimating of instantaneous peak discharge because of deficit of gauging stations in the country. hence, at present study, two models including artificial neural networks and nonlinear multivariate regression were used to predict peak discharge in taleghan watershed. maximum daily mean discharge and corresponding daily rainfall, one day antecedent and...

At Podsused near Zagreb, in an abandoned surface excavation of cement marls, near Kostanjek (Fig. 1) an 83 m thick lithostratigraphical column was investigated comprising layers of Sarmatian and Pannonian age. Five lithofacies units (A, AB, B, C, D) were separated on the basis of their structural-petrographic characteristics. From layers with greater concentrations of fossils, a rich community ...
