Donc quand vous avez mal, vérifier si c’est bien ce muscle là qui vous fait mal, il y a un geste simple à faire, je vous donne le lien vous verrez et vous pourrez agir, avant qu’il ne soit trop tard. Le muscle psoas est fondamental à connaître puisqu’il est responsable d’environ 50% des lombalgies.
Free Classic AudioBooks. Digital narration for the 21st Century 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 intention is to guide staff new to Open Educational Resources in the Biosciences towards those which we believe are valuable examples, and the routes to find them. 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.

The Grey Labyrinth: The Labyrinthians' Exchange by Kevin J. Lin Two exceptionally quick-witted Labyrinthians were invited to a party in their honor. Currently Mathematica is one hundred by hundred houses in area. Our two famed puzzlers, let's call them Samantha and Paul, were both given the address weeks in advance. Paul: I'm afraid I've forgotten the address. Paul and Samantha were being perfectly truthful, and no other information was exchanged apart from this dialog. What was the party's address? Finding Moonshine: Dara O'Briain's School of Hard Sums I am co-hosting a mad comedy maths game show with Dara O'Briain on the TV channel Dave. I was away filming for another series last week when an episode was aired that required some calculus. I got lots of tweets and emails about the problem so thought it worth just explaining how you solve it. Problem: A lifeguard at the beach spots a swimmer in distress in the water. Lets suppose the lifeguard's running speed is v1 and swimming speed is v2. We note that v1=2*v2. There is also a cute physical way you could use to solve this puzzle. When you set the differential to 0 and expand it then they will get a quartic polynomial. At school you learn about a formula for solving quadratic equations. Glorious...if you like that kind of thing. Why do we need to do quadratic equations at school? Solving quadratic equations is something we do every time you catch a ball. This skill is very important in warfare too. We have been solving quadratic equations for millennia. Work has been done by Timothy J.
Learn UNIX in 10 minutes Learn UNIX in 10 minutes. Version 1.3 Preface This is something that I had given out to students (CAD user training) in years past. The purpose was to have on one page the basics commands for getting started using the UNIX shell (so that they didn't call me asking what to do the first time someone gave them a tape).
