Information Literacy in Biology Education: An Example from an Advanced Cell Biology Course

Author(s) : Porter, John R
Description : Information literacy skills are critically important for the undergraduate biology student. The ability to find, understand, evaluate, and use information, whether from the scientific literature or from Web resources, is essential for a good understanding of a topic and for the conduct of research. ...

On the optical--infra-red continuum emission from equatorial discs of supergiant B[e] stars

Author(s) : Porter, John M.
Description : Two models of the circumstellar disc around supergiant B[e] stars are discussed: an equatorial wind model produced by wind bi-stability, and a Keplerian viscous disc model. Both models are successful in providing a site for dust formation once they have cooled sufficiently. However, the optical--i...

On the spin-down of Be stars

Author(s) : Porter, John M.
Description : The spin-down of Be stars due to angular momentum transport from star to disc has been considered. This has been prompted by empirical studies of observed optical and IR line profile studies indicating that the disc is rotating in a Keplerian fashion. It is found that substantial spin-down may occ...

On the warping of Be star discs

Author(s) : Porter, John M.
Description : The theory of radiatively-induced warps in accretion discs is applied to the discs of Be stars. It is found that these discs may develop warps in their inner regions, although once the warp amplitude is large enough then the interaction between the disc and fast radiatively-driven wind will determ...

On the possibility that rotation causes latitudinal abundance variations in stars

Author(s) : Porter, John M.
Description : The effect of rotation of a star on the distribution of chemical species in radiative zones is discussed. Gravity darkening generates a large radiative force on heavy element ions which is directed toward the equatorial plane. Taking iron as an example, it is shown that this force may produce drif...

On outflowing viscous disc models for Be stars

Author(s) : Porter, John M.
Description : It is assumed that Be star discs are driven by viscosity. Emission from disc models is calculated and is confronted with continuum observations. It is found that the outflowing viscous disc models can reproduce the observed IR continuum emission. However, to exist as outflowing discs, either the d...

Crop responses to climatic variation

Author(s) : Porter, John R , Semenov, Mikhail A
Description : The yield and quality of food crops is central to the well being of humans and is directly affected by climate and weather. Initial studies of climate change on crops focussed on effects of increased carbon dioxide (CO2) level and/or global mean temperature and/or rainfall and nutrition on crop prod...
