The psychological refractory period (PRP) paradigm is a dominant research tool in the literature on dual-task performance. In this paradigm a first and second component task (i.e., Task 1 and Task 2) are presented with variable stimulus onset asynchronies (SOAs) and priority to perform Task 1. The main indicator of dual-task impairment in PRP situations is an increasing Task 2-RT with decreasin...

background: ventriculoatrial (va) conduction has an important role in the initiation and maintenance of some arrhythmias. the aim of this study was to evaluate whether clinical and electrophysiological parameters of atrioventricular (av) conduction can predict va conduction. methods: detailed demographic, electrocardiographic, and echocardiographic data were recorded in 54 consecutive patients ...

silica refractory bricks are used especially in the metallurgical industries, due to desirable properties suchas high melting point, rigidity, and high temperatures strength. in this research, different amount of sicwere added to silica refractory containing different binders such as borax, boric acid, calcium nitride,sodium tri poly phosphate, sodium hexa meta phosphate (shmp) and lime. physic...

Initial stages of the refractory degradation process by molten Al-5Mg alloy were investigated analyzing structures caused an interaction with metal during heat cycles. The aggregate, found to be poly-crystalline, consisting cristobalite (SiO2) and mullite (Al6Si2O13), was deteriorated ahead surrounding matrix. Metal permeated into refractory, forming a thin layer along crucible surface below li...

abstract aim and background: evaluation of cognition is fundamental for every comprehensive epilepsy program. we sought to conduct this study to assess memory state of patients with refractory temporal lobe epilepsy before decision for epilepsy surgery. method and materials: in a case-control study, 20 patients with right temporal lobe epilepsy and 20 patients with left temporal lobe epilepsy w...

The differentiation of vasovagal syncope and epileptic seizure is sometimes problematic, since vasovagal syncope may mimic epileptic seizures in many ways. The present report describes a patient who had been diagnosed and treated as having epilepsy with medically-refractory sei-zures for 16 years. Often, unlike epileptic seizures, tonic-clonic convulsions and postictal confusion are uncommon fe...
