Strength and toughness of A l 2 O 3 based ceramics were improved by d i spers ing ZrO,(Y,O,) and nonoxide mate r ia l s such a s Sic , Tic, TiN and B&. S ign i f ican t toughening and hardening were a t t a i n e d i n A1203-Zr0,-Sic and Al,O,-Zr0,-Tic composites.
Ti-TiC-TiC/DLC gradient nano-composite films have been prepared on the NiTi substrates by the technique of plasma immersion ion implantation and deposition (PIIID) combining with plasmaenhanced chemical vapor deposition (PECVD). The influence of C2H2 flow rate ranging from 30sccm to 50sccm on the chemical structure, microstructure, mechanical properties and corrosion resistance of resulting thi...
the debate whether esp teachers need to have knowledge of the specialized field they are teaching has been an issue in the literature over the last two decades. the aim of conducting this study was to explore iranian learners’ and instructors’ beliefs and attitudes concerning the role of specialized knowledge in teaching esp classes. a seventeen item questionnaire was administered to 400 esp le...
BACKGROUND Conventional ultrasound parameters such as the resistance index (RI) are only of limited use in the diagnosis of early allograft dysfunction. We, therefore, performed a prospective study to compare the value of ultrasound contrast media (USCM) with conventional US in the diagnosis of early allograft dysfunction. METHODS A total of 48 consecutive kidney recipients underwent US exami...
OBJECTIVE To compare clean intermittent catheterisation with transurethral indwelling catheterisation for the treatment of abnormal post-void residual bladder volume (PVR) following vaginal prolapse surgery. DESIGN Multicentre randomised controlled trial. SETTING Five teaching hospitals and one non-teaching hospital in the Netherlands. POPULATION All patients older than 18 years experienc...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
BACKGROUND Tic disorders (TDs) are common neuropsychiatric disorders in children. Typical antipsychotics, such as haloperidol and pimozide have been prescribed to control tic symptoms as first-line agents. However, adverse effects have led to the use of newer atypical antipsychotics. Aripiprazole is one of alternatives. The aim of this study was to evaluate the efficacy and safety of aripiprazo...
MgAl2O4/Ti(C,N) composites were synthesized through aluminothermic reaction between Al,TiO 2,MgO powders and phenolic resin in coke bed condition. Effect of addition of carbon black and sugar into the mixture at different temperatures were investigated. The phases and microstructures of samples were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). MgAl 2O4 ...
OBJECTIVE Many neuropsychiatric disorders involve abnormal attentional processing. Systematic investigations of how attention may affect tic frequency in Tourette syndrome are lacking. METHOD Patients performed rhythmic finger movements, approximately once every 2 s. Each movement triggered a unique visual color stimulus. Patients were asked to monitor and remember their finger actions, the e...
