Matematisches Modell des Mikrodrehens

Recently the cost-economy is a very important component in production. That´s why has the modeling so great importance: we can draw conclusions from the attempts made with computer. Thus we can produce results already on lower cost-level. The modeling was introduced by FORM 2D program. This is a FEM program in which we can examine different geometrical dates (cutting depth, cutting edge radius). In the program we are able to set different material quality, machining-tool and coolant (we also can change the feedrate). That´s why we can produce very many kind versions and make examinations, too. Mainly the load, the material-flow, the critical displacement, the temperature-zones and the surface-stress can be examined. From these values we can draw final conclusion applied the geometry. By optimalization the values we are able to define how great cutting depth, cutting edge radius, feedrate are that we work with and which machining-tool is needed

Djinang and Djinba : a grammatical and historical perspective

The Djinang language is the western-most member o-f the "Yolngu" language group. It is spoken by approximately 250 Aboriginal people living in the vicinity of Ramingining, a settlement on the mainland about 20 kilometres south of the Crocodile Islands. Most Djinang speakers live either a t Ramingining» or a t one of several o u tstatio n s, all of which lie within about 30 kilometres of Ramingining. A few Djinang speakers live at Maningrida, and at Milingimbi; and a few women have married men who reside on Elcho Island» and live there with th eir husbands. Djinang is not mutually intelligible with any of the other Yolngu languages or dialects

Variation in monitoring and treatment policies for intracranial hypertension in traumatic brain injury: A survey in 66 neurotrauma centers participating in the CENTER-TBI

Background: No definitive evidence exists on how intracranial hypertension should be treated in patients with traumatic brain injury (TBI). It is therefore likely that centers and practitioners individually balance potential benefits and risks of different intracranial pressure (ICP) management strategies, resulting in practice variation. The aim of this study was to examine variation in monitoring and treatment policies for intracranial hypertension in patients with TBI. Methods: A 29-item survey on ICP monitoring and treatment was developed based on literature and expert opinion, and pilot-tested in 16 centers. The questionnaire was sent to 68 neurotrauma centers participating in the Collaborative European Neurotrauma Effectiveness Research (CENTER-TBI) study. Results: The survey was completed by 66 centers (97% response rate). Centers were mainly academic hospitals (n = 60, 91%) and designated level I trauma centers (n = 44, 67%). The Brain Trauma Foundation guidelines were used in 49 (74%) centers. Approximately ninety percent of the participants (n = 58) indicated placing an ICP monitor in patients with severe TBI and computed tomography abnormalities. There was no consensus on other indications or on peri-insertion precautions. We found wide variation in the use of first- and second-tier treatments for elevated ICP. Approximately half of the centers were classified as having a relatively aggressive approach to ICP monitoring and treatment (n = 32, 48%), whereas the others were considered more conservative (n = 34, 52%). Conclusions: Substantial variation was found regarding monitoring and treatment policies in patients with traumatic brain injury and intracranial hypertension. The results of this survey indicate a lack of consensus between European neurotrauma centers and provide an opportunity and necessity for comparative effectiveness research
