INN Placement Website

Work experience is a valuable experience for all students. It can be hard for students to find work experience and sometimes challenging for them to understand the job market. Students at Innovation North have an opportunity to undertake a Placement year between L5 and L6 and this is something we wish to actively promote, support and encourage. Innovation North had a website which held the details of the work opportunities, it was very dated, contained no images and was cumbersome to search. The project was to create a new website for Innovation North students holding details of all work placements (short, long term, voluntary, paid). Specification for the site included search facilities, providing information and giving reflections from students who had undertaken work opportunities. The website has been developed by three INN students. It has been live since September 2009

The potential impact of Ocean Thermal Energy Conversion (OTEC) on fisheries

The commercial development of ocean thermal energy conversion (OTEC) operations will involve some environmental perturbations for which there is no precedent experience. The pumping of very large volumes of warm surface water and cold deep water and its subsequent discharge will result in the impingement, entrainment, and redistribution of biota. Additional stresses to biota will be caused by biocide usage and temperature depressions. However, the artificial upwelling of nutrients associated with the pumping of cold deep water, and the artificial reef created by an OTEC plant may have positive effects on the local environment. Although more detailed information is needed to assess the net effect of an OTEC operation on fisheries, certain assumptions and calculations are made supporting the conclusion that the potential risk to fisheries is not significant enough to deter the early development of IDEe. It will be necessary to monitor a commercial-scale plant in order to remove many of the remaining uncertainties. (PDF file contains 39 pages.

\u3ci\u3eDay to Day Eats\u3c/i\u3e: Using an Educational Blog to Extend Nutrition Education

An educational blog was created for the purposes of extending learning beyond the reach of organized classes and supplementing the core themes of the Expanded Food and Nutrition Education Program. Focus group members reacted to the format, content, visual appeal, and writing style of the blog and addressed their likelihood of reading the blog because of these elements. Their overall acceptance of the blog as a relevant source of nutrition information confirms the usefulness of this mode of social media for expanding the sharing of information beyond in-person interactions

A Five-year Spectroscopic and Photometric Campaign on the Prototypical alpha Cygni Variable and A-type Supergiant Star Deneb

Deneb is often considered the prototypical A-type supergiant, and is one of the visually most luminous stars in the Galaxy. A-type supergiants are potential extragalactic distance indicators, but the variability of these stars needs to be better characterized before this technique can be considered reliable. We analyzed 339 high resolution echelle spectra of Deneb obtained over the five-year span of 1997 through 2001 as well as 370 Stromgren photometric measurements obtained during the same time frame. Our spectroscopic analysis included dynamical spectra of the H-alpha profile, H-alpha equivalent widths, and radial velocities measured from Si II 6347, 6371. Time-series analysis reveals no obvious cyclic behavior that proceeds through multiple observing seasons, although we found a suspected 40 day period in two, non-consecutive observing seasons. Some correlations are found between photometric and radial velocity data sets, and suggest radial pulsations at two epochs. No correlation is found between the variability of the H-alpha profiles and that of the radial velocities or the photometry. Lucy (1976) found evidence that Deneb was a long period single-lined spectroscopic binary star, but our data set shows no evidence for radial velocity variations caused by a binary companion.Comment: 49 pages, 9 figures, 5 tables, accepted for publication in the Astronomical Journa
