Advanced education and training in bioenergy in Europe

The paper explains how bioenergy education and training is growing in Europe. Employment estimates are included for renewable energy in general, and bioenergy in particular, to highlight the need for a broadly based education and training programme that is essential to build a knowledgeable workforce that can drive Europe's growing bioenergy sector. The paper reviews current provisions in bioenergy at Masters and PhD levels across the 27 members of the EU (EU27) plus Norway and Switzerland. This identifies a very active and expanding bioenergy education provision. 65 English-language Masters Courses in bioenergy (either focussing completely on bioenergy or with significant bioenergy content or specialisation) were identified. 231 providers of PhD studies in bioenergy were found.Masters Course offerings have grown rapidly across Europe during the last five years, but where data is available, enrolment has been quite low suggesting that there is an oversupply of courses and that course organisers are being optimistic in their projections. Existing provisions in Europe at Masters and PhD levels are clearly more than sufficient for short term needs, but further work is needed to evaluate the take-up rate and the content and focus of the provisions. To ensure talented graduates are attracted to these programmes, better promotion, stronger links with the research community and industry, and increased collaboration among course providers are needed. Short Courses of two to five days are an excellent way of meeting post-experience training needs but require further growth and development to serve the needs of the bioenergy community. © 2011 Elsevier Ltd.

Short- and long-term changes in corneal aberrations and axial length induced by orthokeratology in children are not correlated

PURPOSE: To assess the correlation between changes in corneal aberrations and the 2-year change in axial length in children fitted with orthokeratology (OK) contact lenses. METHODS: Thirty-one subjects 6 to 12 years of age and with myopia −0.75 to −4.00DS and astigmatism ≤1.00DC were fitted with OK. Measurements of axial length and corneal topography were taken at regular intervals over a 2-year period. Corneal topography at baseline and after 3 and 24 months of OK lens wear was used to derive higher-order corneal aberrations (HOA) that were correlated with OK-induced axial length changes at 2 years. RESULTS: Significant changes in C3, C4, C4, root mean square (RMS) secondary astigmatism and fourth and total HOA were found with both 3 and 24 months of OK lens wear in comparison with baseline (all P0.05). Coma angle of orientation changed significantly pre-OK in comparison with 3 and 24 months post-OK as well as secondary astigmatism angle of orientation pre-OK in comparison with 24 months post-OK (all P0.05). DISCUSSION: Short-term and long-term OK lens wear induces significant changes in corneal aberrations that are not significantly correlated with changes in axial elongation after 2-years.
