To provide alternatives to the widespread use of nonspeech oral motor exercises for childhood speech sound disorders, speech intervention approaches that have received the highest level of experimental scrutiny are reviewed. Efficacy research over the past decade is critically evaluated according to hierarchical systems for quality and credibility. High standards for adherence to experimental m...

sound power is considered as an excellent measure for evaluating the efficiency of noise controls as well as for comparing noise sources in workrooms. this parameter can be determined by sound pressure or intensity based methods in real conditions of workrooms. this paper aims empirically to compare these in situ methods in relation to a typical industrial machine located in workroom in terms o...

objective: although there are some reports of reduction of obsessive-compulsive symptoms in manic episodes or its exacerbation during depressive episodes, this relationship has not been proved. method: clinical observations of six cases with co-morbidity of bipolar-i-disorder and obsessive-compulsive disorder or symptoms. results: the cases presented here show heterogeneity and variety of the r...

ôbjective: the mood disorder questionnaire (mdq) has been developed as a self-reporting, brief, and easy-to-use screening instrument to improve identification of bipolar mood disorders. the goals of the present study were to examine the prevalence of this disorder and interrelationship of its symptoms by factor analysis of mdq in a group of pregnant women in ïran. methods: ône thousand and eigh...

Single unit recording has been used as a well-known technique to study the electrical behavior of neurons. In this respect, the classical methods are rather expensive. In this study a simple and inexpensive method for single unit recording studies has been introduced. Computer sound card was used for data acquisition. Neural responses were saved via simple sound applicable packages and then ana...

We performed low-frequency sound measurements on He in 98% aerogel in a magnetic field that was varied between 0 and 2130 G at a fixed pressure of 27.9 bar. We monitor the frequency of the second sound like sslowd mode, which is the manifestation of superfluidity of He in the presence of correlated disorder, and use its temperature dependence to calculate the superfluid fraction rs /r. We obser...
