a novel silver (ag) nanocomposite electrode was proposed that fabricated from metal nanostructures and ionic liquids. the combined application of unique properties of nanomaterials and ionic liquids in the design of this ag nanocomposite results in electrodes with interesting advantages compared to the conventional metal disk electrode. in the first part of this thesis, the elecrocatalytic eff...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
The reliability of surface electromyographic (sEMG) variables during swallowing determines the potential usefulness of these measures in swallowing assessment and treatment. This study aimed to establish the reliability of the sEMG measures of the swallowing function of muscles during different swallowing conditions in healthy young and old volunteers. Two groups of volunteers (24 older adults,...
background: estimating pain in patients of intensive care unit (icu) is essential, but because of their special situation, verbal scales cannot be used. therefore, to estimate the level of pain, behavioral pain scale was developed by payen in 2001. objectives: the aim of this study was to investigate the validity and reliability of behavioral pain scale in patients with low level of consciousne...
the reliability of surface electromyographic (semg) variables during swallowing determines the potential usefulness of these measures in swallowing assessment and treatment. this study aimed to establish the reliability of the semg measures of the swallowing function of muscles during different swallowing conditions in healthy young and old volunteers. two groups of volunteers (24 older adults,...

in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
background: pediatric lower urinary tract scoring system (plutss) is a questionnaire contains items for assessment of wetting episodes, voiding frequency and pattern. it is used for screening and evaluation of the response of children with lower urinary tract symptoms to therapy. we studied the validity and reliability of persian translated version of this questionnaire among iranian children. ...
conclusions the results of this study indicates that the single item burnout measure has potential as a brief, sensitive screening measure of burnout due to its brevity, ease of administration and sound psychometric properties and needs to be validated further in larger studies and with other professional groups. results sib scores were highly and positively correlated with mbi-ee scores (r = 0...
objective: early maladaptive schemas are deep feelings or patterns that are formed in childhood and recur later in their lifetime. young has classified these schemas. the purpose of the present study was to validate the young early maladaptive schema questionnaire (yemsq) for early maladaptive schemas in a group of university students. methods: five hundred and seventy nine students were random...
