Genotypic variation in oilseed rape to low boron nutrition and the mechanism of boron efficiency / by James Constantine Roy Stangoulis.

Stangoulis, James Constantine Roy January 1998 (has links)
Bibliography: leaves 132-159. / xv, 159 leaves : ill. (some col.) ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / Boron efficiency in oilseed rape (Brassica napua L. and B. juncea L.) was investigated in a wide range of genotypes. Using a solution culture screening of 10 day old seedlings, root length best described shoot growth response, and was used to characterise a total of 65 genotypes. Varieties and breeders lines tolerant of B-deficient growing conditions were identified, and the screening process validated through field trials. B responses in plants sampled at the 'green bud' stage indicated that vegetative growth is important in B efficiency. Studies were conducted to investigate the mechanism of B efficiency in oilseed rape. Results suggest no association between B efficiency and the capacity to acidify the root rhizosphere, or an increased translocation of B from root to shoot. Boron retranslocation was also studied as a mechanism of B efficiency. / Thesis (Ph.D.)--University of Adelaide, Dept. of Plant Science, 1999?

Implications of natriuretic peptides and endothelin-1 release during myocardial ischaemia

Zhang, Yi. January 1998 (has links) (PDF)
Addenda and corrigenda are tipped-in & numbered leaves 281-282. Copies of author's previously published articles are inserted back end paper. Bibliography: leaves 222-279. Studies were performed in the Langendorff-perfused isolated rat heart, using a paradigm in which atrial distension was prevented. The release of natriuretic peptides and endothelin-1, along with cardiac function was monitored during periods of transient ischaemia or hypoxia. Additional studies were performed in patients undergoing cardiac catheterization.

An Evaluation of the Modality Effect: The Impact of Presentation Style and Pacing on Learning, Mental Effort, and Self-Efficacy

January 2018 (has links)
abstract: The current study investigated how multimedia pacing (learner-control versus system-paced) and presentation styles (visual-only versus audio/visual) impact learning physics concept material, mental effort, and self-efficacy. This 2X2 factorial study randomly assigned participants into one of four conditions that manipulated presentation style (visual-only versus audio/visual) and pacing of the content (system-paced versus learning-controlled). Participant's learning was measured by recording their retention of information and ability to transfer information. Measures of perceived difficulty (mental effort) and perceived ability (self-efficacy) were also obtained. No significant effects were observed in this study which doesn’t support the existence of either the modality or reverse modality effect at least in these noisier online learning environments. In addition, the hypothesis that their effects could be an artifact of experimental design could not be proven as the learner control condition did not yield any significant results. / Dissertation/Thesis / Masters Thesis Human Systems Engineering 2018
