The birefringence of LiInS2 (LIS) crystals in the THz frequency region is investigated by THz time-domain spectroscopy (THz-TDS). The experimental results indicate that LIS has large birefringence and low absorption in the THz frequency region. The optical properties of LIS are quantitatively determined. A sharp absorption caused by a TO-phonon resonance is observed at around 1.70 THz when the ...

The purpose of this study was to examine preservice elementary and secondary English and foreign language teachers’ metaphors and relate their metaphorical images to conceptions of literacy. Specifically, sixty-six participants completed a questionnaire that solicited their sense of teaching. Results indicated that the preservice teachers’ beliefs could be categorized into nine themes. The most...

Patients with chronic kidney disease (CKD) have an increased fracture risk because of impaired bone quality and quantity. Low mineral density predicts in all CKD stages, including advanced (CKD G4-5D). Pharmacological therapy improves reduces moderate CKD. Its efficacy remains to be determined, although pilot studies suggest a positive effect on density. Currently, antiresorptive agents are the...

This comprehensive review of literature includes research studies dating from 1980 to 2005 on expository text structure awareness as well as studies on the effectiveness of expository text structure instruction. The purpose of this literature review is two-fold: 1) To determine the extent to which students’ expository text structure awareness facilitates reading comprehension; and 2) Whether it...

This paper studies how the WWW is evolving and being redesigned to support distributed multiuser applications which involve communication, cooperation, and coordination, as in groupware and work ow systems. The authors have ongoing experience in such a subject, because they are involved in the PageSpace project, which aims at integrating WWWmiddleware with coordination technology. 1 Enhancing t...
