TL;DR: The movement of intestinal mucosal cells was followed using microradioautography after injecting chicks with antibiotics to study the turnover of intestinal epithelium in chicks and the mechanism of migration is not fully understood.

TL;DR: In this article, the authors determined permeation rates and permeate compositions for hexane/heptane mixtures permeating through polyethylene film, and the experimental results were in agreement with the predictions of a semi-empirical model.

TL;DR: As expected, personal development competitiveness was positively correlated with needs for affiliation, whereas hypercompetitiveness was unrelated to affiliation needs, and although hypercompetitive individuals were more aggressive, dominant, and exhibitionistic, this was not the case for personal development competitors.
Abstract: Theory development and research in the area of psychologically healthy competition has been impeded by the lack of a psychometrically sound instrument. Four studies were conducted as part of a research program designed to remedy this deficiency by constructing an individual difference measure of general personal development competitive attitude with satisfactory psychometric properties. In Studies 1 and 2, a 15-item scale was derived primarily through item-total correlational analysis; it demonstrated satisfactory internal and test-retest reliabilities. Studies 3 and 4 were concerned with establishing the construct validity of the scale. Both Studies 3 and 4 showed the scale's discriminant validity through its lack of association with hypercompetitiveness. In addition, its construct validity was seen in its negative association with neurosis and its positive links with personal and social self-esteem and optimal psychological health. Also, as expected, personal development competitiveness was positively correlated with needs for affiliation, whereas hypercompetitiveness was unrelated to affiliation needs. Although hypercompetitive individuals were more aggressive, dominant, and exhibitionistic, this was not the case for personal development competitors.

TL;DR: In this paper, the authors used the quantitative biogeochemical model PnET-BGC to test assumptions about the direct and indirect effects of climate change on a northern hardwood forest ecosystem.
Abstract: A critical component of assessing the impacts of climate change on forest ecosystems involves understanding associated changes in the biogeochemical cycling of elements. Evidence from research on northeastern North American forests shows that direct effects of climate change will evoke changes in biogeochemical cycling by altering plant physiology, forest productivity, and soil physical, chemical, and biological processes. Indirect effects, largely mediated by changes in species composition, length of growing season, and hydrology, will also be important. The case study presented here uses the quantitative biogeochemical model PnET-BGC to test assumptions about the direct and indirect effects of climate change on a northern hardwood forest ecosystem. Modeling results indicate an overall increase in net primary production due to a longer growing season, an increase in NO3– leaching due to large increases in net mineralization and nitrification, and slight declines in mineral weathering due to a reduction i...
