This entry provides a thorough introduction to computer-assisted and -aided language learning (CALL). It starts by providing the definition and history of CALL and associated relevant terms. Then, an existing CALL methodological framework is presented and discussed. This is then followed by an overview of the current state of CALL by citing some representative examples of its uses and discussin...

Results: Mean age of the study population was 34.7 ± 8.5 and mean duration of work was 16.5 ± 7.9 years. The prevalance of Dental technicians’ pneumoconiosis (DTP) was 11.1%. The most common opacity in HRCT was round opacity with a rate of 89.7%. The rate of large opacity was %14.3. There was positive correlation between ILO score and HRCT score. Negative correlation was found between ILO and H...

BACKGROUND: Outpatient craniotomy, biopsy, and spinal decompression have been performed at our center for more than a decade. Early feasibility studies suggest that they are safe, successful, cost-effective, and well-tolerated by patients. However, a largescale study of this magnitude has not been performed. OBJECTIVE: To characterize postoperative complications and the rate of successful disch...

Climate change modulates the effects of solar UV radiation on biogeochemical cycles in terrestrial and aquatic ecosystems, particularly for carbon cycling, resulting in UV-mediated positive or negative feedbacks on climate. Possible positive feedbacks discussed in this assessment include: (i) enhanced UVinduced mineralisation of above ground litter due to aridification; (ii) enhanced UV-induced...

at least among some urban populations.7 A third hypothesis is based on the stages of an adolescent’s acquisition of lesbian or bisexual identity. “Heterosexual immersion” may be one strategy for responding to the identity confusion stage of development: “Some adolescents establish heterosexual involvements in hopes of ‘curing’ themselves of their homosexual interests....In some cases, an adoles...

The pluripotent mammalian epiblast undergoes unusually fast cell proliferation. This rapid growth is expected to generate a high transcriptional demand, but the underlying mechanisms remain unknown. We show here that the chromatin remodeler Chd1 is required for transcriptional output and development of the mouse epiblast. Chd1 embryos exhibit proliferation defects and increased apoptosis, are s...

Accurate prediction of in vivo hepatic drug clearance using in vitro assays is important to properly estimate clinical dosing regimens. Clearance of low-turnover compounds is especially difficult to predict using short-lived suspensions of unpooled primary human hepatocytes (PHHs) and functionally declining PHH monolayers. Micropatterned cocultures (MPCCs) of PHHs and 3T3-J2 fibroblasts have be...
