Computers have been used for language teaching ever since the 1960's.Learning a second language is a challenging endeavor, and, for decades now, proponents of computer assisted language learning (CALL) have declared that help is on the horison. We investigate the suitability of deploying speech technology in computer based systems that can be used to teach foreign language skills. In this case,...

introduction: epidermoid tumors comprise 1% of intracranial tumors. although reported, intraosseous epidermoid tumors are even more rare. cystic lesions of the petrous apex are uncommon and surgically challenging; the most rare pathology is presumed to be epidermoid.rncase presentation: this is a case of a 61-year-old woman with a large skull-base tumor extending inferiorly from the c1-c2 artic...

background: total and partial gastrectomy is commonly used to treat gastric carcinoma or other benign or malignant conditions of the stomach. laparoscopic-assisted distal gastrectomy is an alternative approach for treating mucosal gastric cancer. many investigators have assessed the safety, efficacy, and feasibility of this procedure.rnobjectives: the aim of present study is to compare the outc...

background: the recent developments in tissue doppler imaging (tdi) now more than ever permit the quantification of the myocardial function. in the current systems, tissue tracking or displacement curves are generated from color tissue doppler data through the instantaneous temporal integral of velocity-time curves. methods: the purpose of the present study was to assess regional myocardial dis...
