For a number of years the German as well as the European forging industry has been facing some sustainable market trends, which have led to a paradigm shift that still lasts. The continuing shift of mass production to low cost countries and shorter product life cycles force the manufacturer to greater flexibility and efficiency in development and manufacturing. There is still a certain potential for cost savings. Utilizing these opportunities becomes especially important for very complex and energy-consuming incremental forming technologies like open die forging and ring rolling. Additional (local) property demands of the customers for their parts/components become more and more standard requirements - a change of design-oriented towards property-oriented manufacturing. In this context, the approach of an integrated simulation of entire process chains is becoming increasingly essential.

The curing phase is the most time consuming part in rubber injection moulding. The determination of a suitable curing time is a complex issue, despite extensive adjusting trials, since the evaluation of the part quality such as the curing degree is often just visually detectable for a significant undercure (fig. 1a) and frequently can only be identified after a precise examination (fig. 1b). The systematic injection moulding simulation with Varimos presents an effective solution because the Varimos methodology already allows to virtually detecting the effects of process parameters and their interactions and to visualise for instance impending undercure (fig. 1c). It enables to optimise part, mould and process automatically to the desired quality criteria. Consequently, one succeeds not only in saving valuable machine time otherwise expended for process development, but will also have the ability to define the processing window more precisely and, thus, improving the efficiency of the process while at the same time ensuring the required process stability. This methodology was successfully investigated and demonstrated using a thick-walled rubber part in course of the RubSim project which was carried out by the Polymer Competence Center Leoben GmbH in collaboration with the Institute of Injection Molding of Polymers of the Montanuniversität Leoben and the industrial partner companies SKF Sealing Solutions Austria GmbH, Engel Austria GmbH, Simcon kunststofftechnische Software GmbH, and Dr. Gierth Ingenieurgesellschaft mbH.
Ankylosing spondylitis as seen by those affected - Experiences collected by the German ankylosing spondylitis patient organisation [Der Morbus Bechterew aus Sicht der Betroffenen: In der Deutschen Vereinigung Morbus Bechterew e. V. gesammelte Erfahrungen]

An extensive exchange of experience among patients with ankylosing spondylitis (AS) has been made possible by the foundation of the Deutsche Vereinigung Morbus Bechterew (DVMB) in Germany and similar organisations in other countries. Other aims of these organisations are the establishment of disease-specific group therapy in many towns and communities in the respective country, the distribution of profound information on the disease, and the representation of patients affected in the health system and law. Scientific surveys conducted by DVMB constitute a valuable contribution to epidemiological and medical care research. Since only a small number of the patients with AS in a country are members in a disease-specific patient organisation, it is important that the patients receive from their doctors not only an early diagnosis and therapy but also early information on the possibilities to influence the course of the disease by appropriate behaviour and adaptation of their living and working environment. There is no rheumatological cure for AS. A large number of patients with AS reported, however, that they succeeded to get rid of their complaints by the neurocognitive therapy, without any further treatment. The therapeutic success which was confirmed by a pilot study, indicates that the central nervous system and traumatic experiences stored therein, play an important role in the development and maintenance of ankylosing spondylitis. © Georg Thieme Verlag KG Stuttgart - New York.

Material confusions in the production process can have severe consequences for the later usage of steel products. Thus steel manufacturers strive for continuous and reliable material tracking. The automatic stamp-identification system in operation at Georgsmarienhütte features high fault detection rates, reduces manual detection efforts and eliminates errors caused by manual fault detection techniques. The fault detection rate has averaged 95 % since the initial start-up of the system two years ago.

Characterising the mechanical properties of elastomeric components by utilising standardised test specimens does not allow any prediction with regard to their performance under operating conditions. For that reason the parameters required have to be determined directly at the functional positions of even very complex and filigree parts. The present study addresses the capabilities being offered by the force-displacement sensor LNP nano touch in this particular field.

Railway bridges using steel-concrete composite cross-sections play a different role in the countries of Europe. The assessment of the economic efficiency during a life cycle differs considerably. The design of composite bridges reveals innovative approaches. By means of composite construction which is in use in France and in Germany in recent times, the range of application is figured out and the differences in construction become visible. © Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

Aim: Introduction of initial results from the German federal public reporting system on the quality of nursing home care entiteled Pflege-Transparenzvereinbarung Ambulant (PTV-A). Analysis of incentives encouraged by the PTV-A. Strengthening of both, outcome and quality-of-life- parameters. Method:Presentation and comparative discussion of quality-assessments obtained in 36 in-patient respectively 48 out-patient nursing care services. Derivation of incentive profiles verified both in a case study and against international scientific body of evidence. Results: Due to an ambulant choice of service index, quality-assessments in out-patient facilities are normally inferior to comparable results from nursing homes. Moreover, neither criteria, nor assessment framework or display format from the PTV-A motivate nursing care providers to excellence. Instead resource adjustment from people-intensive care to administrative structures is triggered. There is a certain probability, that the recorded mean of quality assessment in out-patient services improves while the quality of ambulant nursing care may coincidentally drop (adverse effect). Conclusion: The PTV-A sets a starting point for improved quality of nursing care. Additional outcome and quality-of-life-criteria as well as supplemental assessment grades and valid tools to recognise excellence in care facilities are needed. Finally, the attributes characteristic to ambulant care e. g. involvement of relatives into the care process as well as out-patient choice of service index need to be integrated into the PTV-A criteria and assessment framework.© Georg Thieme Verlag KG Stuttgart · New York.

Existing hydraulic controls operate with a main control valve wherein the inlet and outlet control edges are actuated simultaneously by force through common piston. A new design now uncouples the opening of inlet and outlet control edges by means of individual pistons. An electronic coupling of both slide valves thus allows an independent, optimal adjustment for every operating condition. Eliminating unnecessary throttling points is a new safety functions. Depending on the operational mode that yields not only higher processing speeds but also energy savings with over 30%. Simultaneously, the durability of not so heavily loaded motor/pump unit increases and the heat exchanger for the hydraulic oil can be designed to be considerably smaller.

Simulator training is a key component in achieving and preserving on the long term the necessary expertise of plant personnel also required by the authorities. In this way, it makes an important contribution to the safe operation of nuclear power plants. Simulators are a com ponent in the training of operating personnel of nuclear power plants which allows operators to be prepared in a focused and practice-oriented way for their activity in everyday plant operation and for possible accident simulation. The simulator center is supported by five nuclear power plant operators: the German EON Kemkraft GmbH, RWE Power AG, EnBW Kraftwerke AG, and Vattenfall Europe Nuclear Energy GmbH companies as well as the Netherlands N.V. Electriciteits-Produktiemaat- schappij Zuid-Nederland. They established a joint enterprise in Essen which performs in one central place the duty of simulator training incumbent upon all nuclear power plants.
