Open Educational Resources Project (Collections Strand) - OeRBITAL
UK Centre for Bioscience OER project - Phase 2 The UK Centre for Bioscience sucessfully bid for funding to undertake a 'Collections Strand' Open Educational Resources project over 2010-2011 following its success with the phase 1 (OER pilot projects) Interactive Laboratory and Fieldwork Manual for the Biosciences project. Working with ten discipline consultants from across the country we have produced a wiki for the benefit of the bioscience community to explore the potential of OERs across a range of disciplines. The OeRBITAL project wiki is available at: The story behind finding, evaluating and enhancing OERs is also captured here, so that we might share and develop a realistic approach to assist other OER users (and developers) with JISC and HEFCE funded projects. Members of the bioscience community are encouraged to continue to develop and update the collection. Further details - What the project is about

Глицерин
Глицери́н (1,2,3-триоксипропан, пропантриол-1,2,3) — простейший представитель трёхатомных спиртов. Представляет собой вязкую прозрачную жидкость. Физические свойства[править | править исходный текст] Глицерин — бесцветная, вязкая, очень гигроскопичная жидкость, смешивается с водой в любых пропорциях. Химические свойства[править | править исходный текст] Химические свойства глицерина типичны для многоатомных спиртов. Взаимодействие глицерина с галогеноводородами или галогенидами фосфора ведёт к образованию моно- и дигалогенгидринов. При дегидратации он образует токсичный акролеин: и окисляется до глицеринового альдегида CH2OHCHOHCHO, дигидроксиацетона CH2OHCOCH2OH или глицериновой кислоты CH2OHCHOHCOOH. Место глицерина в обмене веществ живых организмов[править | править исходный текст] Получение[править | править исходный текст] Глицерин впервые был получен в 1779 году Шееле при омылении жиров в присутствии окислов свинца. Производные глицерина[править | править исходный текст] На русском языке:
