objective: interaction between genetic and environmental factors is considered as major factors in schizophrenia (scz). it has been shown that dopaminergic and noradrenergic neurotransmission dysfunction play an essential role in the scz pathogenesis. this study aimed to find the impact of functional 19-bp insertion/deletion (ins/del) polymorphism in dopamine beta-hydroxylase (dbh) gene on scz ...

Dynamic Analysis of an axially moving cable with time dependent tension and velocity isstudied in this paper. Tension force and the moving speed are assumed to be harmonic.It is found that there exists a specific value of speed in which natural frequency of the system approacheszero. This specific speed for such a critical condition is called critical speed and it will be proved thatincreasing ...

The present Critical Discourse Analysis (CDA) study aimed to explore the probable ideological manipu- lations exerted in three translations of an English political book entitled The Coup by Ervand Abraha- mian. This comparative qualitative study was conducted based on Farahzad‘s three-dimensional CDA model. The textual, paratextual, and ...

The coordination of gestures in consonant clusters differs across languages and hence must be a learned aspect linguistic knowledge. Precisely pinning down the relation used particular language, or for cluster type, has been facilitated by recent research showing that relations structure kinematic variation unique ways. We apply these methods to hitherto under-explored topic, created via vowel ...

This paper is concerned with behavior analysis and improvement of wind turbines with Doubly Fed Induction Generator (DFIG) when using a new fractional-order control strategy during wind variations. A doubly fed induction generator, two types of variable frequency power electronic converters and two input wind waveforms are considered. A fractional-order control strategy is proposed for the wind...

In this paper a nonparametric latent variable model is estimated without specifying the underlying distributions. The main idea is to estimate in a first step a common factor analysis model under the assumption that each manifest variable is influenced by at most one of the latent variables. In a second step nonparametric regression is used to analyze the relation between the latent variables. ...

Given a Boolean formula in disjunctive normal form, the variable deletion control set problem consists in finding a minimum cardinality set of variables whose deletion from the formula results in a DNF satisfying some prescribed property. Similar problems can be defined with respect to the fixation of variables or the deletion of terms in a DNF. In this paper, we investigate the complexity of s...

abstract   introduction: the aim of present study was the investigation of simple and multiple correlations of motivational strategies (self-efficacy, achievement goals and test anxiety) with english language academic performance.   methods: for this purpose, 296 pre university students (139 girls and 157 boys) were selected by clustery random sampling and motivational strategies and achievemen...

In humans, rodents and horses, pigmentary anomalies in combination with other disorders, notably intestinal aganglionosis, are associated with variants of the endothelin type-B receptor gene (EDNRB). In an inbred Cameroon sheep flock, five white lambs with light blue eyes were sired from the same ram and died within a few hours up to a few days after birth, some of them with signs of intestinal...
