Rise Project OpenKnit : une imprimante de vêtements open-source Dans l'histoire des inventions, le métier à tisser tient une place particulière tant il traverse les époques et les civilisations, et témoigne des progrès technologiques réalisés par l'homme au fil de l'Histoire. Les premiers outils destinés à croiser des fils de laine pour confectionner des tissus sont apparus dès le néolithique, et ils n'ont cessé depuis de se perfectionner en profitant ou en impulsant des sauts technologiques, de plus en plus rapprochés. Les grandes innovations sont ainsi apparues vers 3000 avant J.-C (fils de chaîne tendus), 1400 avant J. Il n'y avait donc aucune raison que le métier à tisser ne soit pas aussi concerné par la révolution du numérique, de l'économie du partage et du DIY. Inspiré par le succès des imprimantes 3D basées sur le modèle open-source RepRap, le projet Openknit vise à créer un métier à tisser mécanisé libre et ouvert, reproductible par quiconque souhaite construire sa propre machine à partir des plans.

Three Mile Island accident The Three Mile Island accident was a partial nuclear meltdown which occurred in one of the two Three Mile Island nuclear reactors in Dauphin County, Pennsylvania, United States, on March 28, 1979. It was the worst accident in U.S. commercial nuclear power plant history.[1] The incident was rated a five on the seven-point International Nuclear Event Scale: Accident With Wider Consequences.[2][3] The accident began with failures in the non-nuclear secondary system, followed by a stuck-open pilot-operated relief valve in the primary system, which allowed large amounts of nuclear reactor coolant to escape. The mechanical failures were compounded by the initial failure of plant operators to recognize the situation as a loss-of-coolant accident due to inadequate training and human factors, such as human-computer interaction design oversights relating to ambiguous control room indicators in the power plant's user interface.

Introduction to Radioecology | Environmental Radiation Protection Curriculum Instructor: Gary Mills Course Description: This course will be an introduction to the fates and effects of radionuclides (radioactive isotopes) and their environmental impacts. Class Schedule and Grading: This three-week class will consist of five two-hour classes per week with lectures on Mondays and Tuesdays, Case Studies on Wednesdays, a field trip or lab demonstration on Thursdays, and discussions/exams on Fridays. Prerequisites: Chem I and II, Calculus I and II, General Ecology, or approval from instructor Course Innovation: The case studies that will be presented illustrate the issues of radionuclide release across an increasing scale, both in terms of severity and complexity. The course will also include a field trip to Pond B of the Savannah River Site. Preliminary Course Schedule: For registration information contact Dr.

Maps for Advocacy, a set of Tactical Tech tools How can advocacy groups highlight complex issues such as human rights abuses, protest marches and vanishing forests?Thankfully there are techniques tools now available to powerfully represent these issues as maps. Tactical Tech recognised the power of maps in projects such as the Darfur Project and mapping done by ALTSEAN-Burma, and produced our Maps for Advocacy booklet as an introduction to geographical mapping techniques.

Investigations in radioecology might include aspects of field sampling, designed field and laboratory experiments and the development of predictive simulation models. This science combines techniques from some of the more basic, traditional fields, such as physics, chemistry, mathematics, biology, and ecology, with applied concepts in radiation protection. Radioecological studies form the basis for estimating doses and assessing the consequences of radioactive pollution for human health and the environment.
