The Italian hadron-therapy centre CNAO (Centro Nazionale di Adroterapia Oncologica) [1] is designed for the treatment of tumours with proton and light ion beams and to clinical and radiobiological research. The design consists of two ECR ion sources, a 7 MeV/u injector linac identical to the linac of the Heidelberg ion therapy centre HIT [2][3] and a 400 MeV/u synchrotron. GSI delivers technica...
Der Beitrag plädiert für ein normalisierendes Verständnis von Widerstand in Prozessen der Schulentwicklung. Dem Ansatz einer kulturtheoretisch-praxeologischen Schulentwicklungsforschung folgend wird eine Heuristik zur Analyse Praktiken des Widerstands vorgestellt und auf Fallvignette aus Begleitforschung zum Schulversuch PRIMUS Nordrhein-Westfalen bezogen.
A survey of 6000 schoolchildren discovered 36 cases of unilateral and 60 cases of bilateral hallux valgus, defined as a metatarsophalangeal angle of more than 14.5 degrees, measured on standing radiographs. Metatarsus primus varus was found not only in the early stages of hallux valgus but in the unaffected feet of children with unilateral hallux valgus. Adduction of the first metatarsal is not...

background: the monte carlo method is the most accurate method for simulation of radiation therapy equipment. the linear accelerators are currently the most widely used machines in radiation therapy centers. methods: in this work, a monte carlo modelling of the siemens oncor linear accelerator in 6 mv and 18 mv beams was performed. the results of simulation were validated by measurements in wat...
Of the several cases of accidents, fall a vehicle from ship during loading and unloading occurred due to break in clevis ramp door. This study focused on construction door LCT Lady Primus 39.5 m. The purpose this is determine voltage characteristics that occur construction, location most critical components safety factor value under each condition. research uses finite element method (FEM) refe...
