An analytic model comprising the various moves in error correction sequences in second-language classrooms is developed & applied to a database of classroom interaction with a view to relating teachers' corrective feedback with students' responses. The corpus was generated from…

This thesis examines the role nineteenth-century women's literary journals, specifically Ladies' Journal (1823--1833), played in the development of Russian literature. The longest-lived and most-circulated of the pre-Soviet women's literary journals, Ladies' Journal was well-positioned to have contributed to the on-going…

Los tipos de trasplante de órganos habituales son cuatro: alogénico, isogénico, autólogo y xenogénico. Las principales complicaciones del trasplante son las infecciones y el rechazo. La prevención del rechazo a través del empleo de medicamentos inmunosupresores continua siendo el mayor…

A spectroelectrochemical study of the adsorption and oxidation of serine and alanine on Pt(111) electrodes has been carried out in 0.1 M HClO4 solutions. From the voltammetric and FTIR spectroscopic results, we concluded that adsorbed cyanide is formed at the…

The purpose of this research was to gain an understanding of how music education students come to think of themselves as music educators. Guided by the thematic framework, "learning from experience", which draws upon research relating to constructivist theory and…

Procedures for the selection of subjects for participation in randomized clinical trials--usually formalized as eligibility criteria in the study protocol--have both scientific and ethical implications. In this thesis, I undertake an examination of eligibility criteria at three stages in the…

Although it has been demonstrated that NO inhibits the proliferation of different cell types, the mechanisms of its anti-mitotic action are not well understood. In this work we have studied the possible interaction of NO with the epidermal growth factor…

ABSTRACT: Fifty-three endophytic enterobacteria isolates from citrus, cocoa, eucalyptus, soybean, and sugar cane were evaluated for susceptibility to the antibiotics ampicillin and kanamycin, and cellulase production. Susceptibility was found on both tested antibiotics. However, in the case of ampicillin susceptibility…

The chromatic sensitivity of holographic optical elements for use in optical interconnect systems is quantified using an entropy merit function. The influence of broad-band illumination on axial irradiance and intensity is studied showing that the best imaging point obtained with…

A novel method for the characterization of the processing of both absorption and phase holograms is proposed. Differently from the previous models, the square root of the diffraction efficiency of the processed hologram was directly related to the amplitude of…
