The purpose of this study was to monitor the setting behaviour and elastic modulus of luting cements using an ultrasonic device. The ultrasonic equipment comprised a pulser-receiver, transducers and an oscilloscope. The transit time through the cement disk was multiplied by the thickness of the specimen, and the sonic velocity within the material was then calculated. The sonic velocities of the...

In conclusion, the model itself is theoretically sound and the results of the eY cacy study are encouraging. Future research might usefully be directed at invest igating the relative importance of each of the aspects of the model, the eY cacy of the planned breaks and the eVects of parent education and involvement in therapy. The model oVers a broad outline to aid clin icians in planning eVect ...

as onomatopoeic words or expressions are attractive, the users of languages in the fields of religion, literature, music, education, linguistics, trade, and so forth wish to utilize them in their utterances. they are more effective and imaginative than the simple words. onomatopoeic words or expressions attach us to the real nature and to our inner senses. this study aims at familiarity with on...

This paper reports on the effect of fiber crimp frequency on sound absorption capability of staple polypropylene nonwoven batts. Stuffer box was used to impart crimp to spun tow. Crimping of the tow renders the fibers the required textile applicability. In this work, polypropylene batts composed of staple fibers with linear densities of 9, 14, and 18 denier were employed. Three crimp frequency ...

A B S T R A C T Introduction:We investigated differential role of cortical and subcortical regions in verbal and non-verbal sound processing in ten patients who were native speakers of Persian with unilateral cortical and/or unilateral and bilateral subcortical lesions and 40 normal speakers as control subjects. Methods: The verbal tasks included monosyllabic, disyllabic dichotic and diotic tas...

BACKGROUND Phonological therapy in subjects with phonological disorders. AIM To compare the efficacy of three contrastive approach models in three different severities of phonological disorder. METHOD Participants of the study were nine subjects with phonological disorders, with ages ranging between 4:2 and 6:6 years. All subjects were evaluated prior to and after phonological therapy. Thre...
