Purpose – The purpose of this paper is to examine how different aspects of an assessor’s context, in particular their knowledge of a search topic, their interest in the search topic and their confidence in assessing relevance for a topic, affect the relevance judgements made and the assessor’s ability to predict which documents they will assess as being relevant. Design/methodology/approach – T...

To improve the performance of exercise stress testing in the diagnosis of effort angina while minimizing risks of serious complications, we evaluated an impulse response of ST changes, which is a transient ST response resulting from a hypothetical, strenuous-impulselike exercise, without actually imposing the strenuous load. To obtain the impulse response, subjects walked intermittently accordi...

Identifying unilateral vestibular failure of the semicircular canals (SCC) is important in vertigo and dizziness disease. There are different vestibular tests available: rotatory testing (RT), bithermal caloric irrigation (CI) and the video-head-impulse test (vHIT). This review comments on the current knowledge and on economic aspects of the testing methods. RT are a very specials tests and sho...

Audiological and vestibular testing plays an important role in diagnosis of Menière’s disease,as disease per se and as staging diagnosis. A battery of tests are recommended in order to have a better evaluation of the disease. Audiological testing includes pure tone audiometry, with highlights of bone conduction especially in acute episodes of Menière’s disease, speech audiometry and glycerol te...

This paper presents the methodology for the design of Low pass FIR digital filter using hybrid Differential Evolution (DE) method. It is an evolutionary algorithm that exhibits the features of both the basic DE and HookeJeeves exploratory move to attain the optimal solution. The basic DE and exploratory move have the capability to exploit and explore the search space to design the optimal filte...

Video head impulse test (v-HIT) is a quick and non-invasive to evaluate vestibular function compared the caloric test. The latter is, however, needed decide on optimal side for cochlear implantation avoid inducing bilateral are flexia. This study evaluates effectiveness of using v-HIT select implant (CI) candidates who require subsequent testing before implantation.

the impulse oscillation system (ios) measures respiratory impedance (zrs) in terms of resistance (rrs) and reactance (xrs) at multiples of 5 hz. these measurements can be used clinically to help diagnose and monitor respiratory disorders, independent of effort. there is, as yet, no information on reference values for ios in iranian adolescents. the predictive equation for resistance and impedan...

Zinc is a substance that regulates neural excitability by binding whit sodium channel and potassium channel. The efficiency of free zinc ion, make down the neural survival rate, reduced the peak amplitude of Na+ and make depolarization Na channel, increased the peak amplitude of transition outward k+ currents and delayed rectifier. Also it is an effective blocker of one subtype of tetrodoxine (...
