The effects of carbon content on the dynamic and static softening mechanisms of Ti microalloy steels were investigated both in ferrite and austenite regions. The results obtained showed that recrystallization rate decreased as the percentage of carbon content was increased from 0.0035 to 0.110. This is due to the Ti(CN) and TiC precipitates and also the free carbon content. In the ferrite reg...

Titanium has limitations in its clinical performance in dental and orthopaedic applications. This study describes a coating process using pulsed laser deposition (PLD) technology to produce surfaces of titanium carbide (TiC) on titanium substrates and evaluates the biological response both in vitro and in vivo. X-ray photoelectron spectroscopy (XPS) analysis revealed the presence of 18.6-21.5% ...

tics are sudden, recurrent and stereotyped motor movements or vocalizations. dopamine blockers are the main pharmacological agents used in the management of tics. opioid antagonists have been reported to have been effective in the management of tics. in this article, two patients with chronic motor tic disorder are reported, whose symptoms were disappeared by using opioid substances.

The human pathogen Group A Streptococcus (Streptococcus pyogenes, GAS) is widely recognized as a major cause of common pharyngitis as well as of severe invasive diseases and non-suppurative sequelae associated with the existence of GAS antigens eliciting host autoantibodies. It has been proposed that a subset of paediatric disorders characterized by tics and obsessive-compulsive symptoms would ...

background: obsessive-compulsive disorder (ocd) symptoms and the related disorders are subsumed under chronic psychiatric disorders which are of psychosocial and therapeutic importance. in most studies, the mean age of onset of significant ocd symptoms is adolescence period. the aim of this study was to evaluate ocd symptoms, tic disorder, body dysmorphic disorder (bdd) and trichotilomania amon...

OBJECTIVE This study aimed to investigate comorbidity, and sociodemographic and clinical characteristics in children and adolescents with Tourette's syndrome (TS) and chronic motor or vocal tic disorder (CMVTD), and to determine the predictors of tic disorders. MATERIALS AND METHODS In all, 57 children and adolescents with TS and CMVTD were compared with a control group. Data were obtained us...

In this work, TiC/M2 high speed steel metal matrix composites (MMCs) were prepared using the ball milling method and laser powder bed fusing process. By controlling TiC content in TiC/M2HSS, grain size, phase composition, frictional wear properties of samples enhanced. The results showed that when TiC/M2HSS was supplemented with 1% TiC, surface microhardness increased to a maximum value volume ...

We determined the levels of a,-protease inhibitor, the plasma trypsin-inhibiting capacity (TIC), and elastase-inhibiting capacity (EIC) in 29 nonsmokers and 30 smokers, who were healthy volunteers matched for age (mean age, 39 ± 12 years [± SD]). The functional activity of plasma a1protease inhibitor (in micrograms of enzyme inhibited per microgram of a,-protease inhibitor) was slightly but sig...

Coevolutionary techniques in combination with particle swarm optimization algorithms and neural networks have shown to be very successful in finding strong game playing agents for a number of deterministic games. This paper investigates the applicability of a PSO coevolutionary approach to probabilistic games. For the purposes of this paper, a probabilistic variation of the tic-tac-toe game is ...
