Prevalence of tobacco use among nurses and nursing students is disproportionally high in Germany. However, from a public health perspective they are considered to be an important group for delivering smoking cessation interventions. As delivery of tobacco-related treatment depends on own smoking status, smoking prevention and cessation among the nursing professions is indicative for improving nurse and public health.To evaluate the feasibility and effects of a comprehensive tobacco prevention and reduction program on psychosocial and environmental factors related to smoking behavior of nursing students.Between 2014 and 2015, a non-randomized, controlled feasibility study was conducted in 12 schools of nursing with 397 nursing students in Germany. Students in the intervention group received a program (ASTRA) consisting of an introductory session, steering committee workshop, stress prevention lessons, evidence-based smoking cessation intervention, and action project. Six months after baseline assessment, change in smoking-related protective and risk factors was determined. Secondary endpoints included smoking behavior.The program was implemented in total in 5 of 7 intervention schools. About one third of smoking nursing students participated in a cessation intervention. The program seems to do better than a minimal intervention booklet in four primary outcomes: perceived descriptive, subjective, and injunctive norms towards smoking and nursing as well as perceived social support. As anticipated, there was no change in smoking behavior.The applied approach is feasible and able to improve important smoking-related norm perceptions of student nurses and perception of social support. However, additional context measures to influence the settings of nursing education currently rather supporting smoking seem to be necessary in order to promote smoking cessation among nursing students and to scale up implementation of the program.

Initial situation: The operation of small power plants (e.g. for households) for electricity, heat and cold (micro trigeneration) requires new solution trials. There are systems required, which are user-friendly, low-maintenance, economic. The new Schukey engine unites provide these attributes. The Schukey engine shows an ingenious concept (universality as a concept) and works at a temperature of 120C steam or 1.1 bar. The cooling is directly made by air. In the Central Europe 5 kWel and 20 kWth are provided to 40 m CPC-collectors. A household can cover of the annual heat demand (approx. 27 MWh) and current demand (approx. 4 MWh). Difficulties: The Schukey technology is deciding in a very early developmental stage and thus it still requires a comprehensive development work: (1) Transmission compression, (2) Mass diminution (rotors & case), (3) coordination the control of the pressure volume temperature on the optimal expansion relationship of the domestic operating range, (4) creation of a thick system despite a smaller performance (max. 3% mass loss), (5) Integration into the primary domestic energy system or power supply system. Aims: 1. The priority aim of the project is the development and test application of a compact combination plan (10 kg of engine weight for 5 kWel) for a production of current, heat and cold in the smaller performance are by using of the Schukey technology short microsolar trigeneration. 2. It should be directed a simple, standardized, economic and suitable for practices solution (for a Schukey engine should be obtained a performance area of 2-2.5kWel and a pure engine manufacturing between 300 and 500 ). 3. The project should aim for that specific current prime costs, which be directed in the area of the net parity (these should be long running). The cold of use should be provided by approx.0.5 /kWh (conventional air conditioners: 0,12 /kWh).

We sought to assess whether multiple biomarkers would correlate with the outcome and could improve event prediction in nonST-segment elevation acute coronary syndrome populations with low event rates. Nine inflammatory, ischemic, or neurohormonal biomarkers were measured within 48 hours after symptom onset in 440 patients with nonST-segment elevation acute coronary syndrome from the ARCHIPELAGO (Irbesartan in Patients With Acute Coronary Syndrome Without ST Segment Elevation) trial. We assessed the relation between biomarkers and ischemic or heart failure composite end points at 2 months of follow-up. We also evaluated whether biomarkers could improve the predictive performance of the validated and well-performing Global Registry of Acute Coronary Events risk score. Among all biomarkers measured at baseline, only interleukin-6 correlated with the ischemic end point (adjusted odds ratio 1.69, 95% confidence interval [CI] 1.23 to 2.31). The independent correlates of the heart failure end point were B-type natriuretic peptide (adjusted odds ratio 3.16, 95% CI 1.99 to 5.03), aldosterone (adjusted odds ratio 1.57, 95% CI 1.14 to 2.16) and matrix metalloproteinase-9 (adjusted odds ratio 0.64, 95% CI 0.46 to 0.88). The Global Registry of Acute Coronary Events score predicted poorly the ischemic end point (area under the curve [AUC] 0.591) and fairly (AUC 0.775) the heart failure end point. The performance of the models was significantly improved by the introduction of interleukin-6 (AUC 0.685) for the ischemic end point and of the 3 biomarkers (AUC 0.874) for the heart failure end point. In conclusion, the interleukin-6 level only, and B-type natriuretic peptide, aldosterone, and matrix metalloproteinase-9 together, independently correlated with the ischemic and heart failure end points, respectively. The Global Registry of Acute Coronary Events risk score's performance was significantly improved with a biomarker strategy. In low-risk populations, a strategy using these biomarkers might help in identifying patients at greater risk of additional events. © 2010 Elsevier Inc. All rights reserved.

In vehicle applications, brushless dc drives (BLDC drives) are commonly used as auxiliary drives, if enhanced operating life time is required. For these drives permanent magnet synchronous machines are used. The local flux density curves in the iron parts of the stator of these machines are not sinusoidal. Beside unidirectional magnetization, also elliptical magnetization occurs in general. This requires a determination of iron losses for general elliptical magnetization. This paper describes a method based on the loss data for unidirectional magnetization. The results are compared to measurements. © 2015, Springer Verlag Wien.

Abstract For dimensioning and planning plants and apparatuses as well as optimizing, the collection of rheological data is indispensable. Characterizing bio-suspensions rheologically is often impossible or can be done only with insufficient precision because of their physical properties. Using a special large-scale tube viscometer that has been developed at Hanover University of Applied Sciences and Arts, rheological data from bio-suspensions were collected directly in agriculture biogas plants without any pretreatment. The sizes measured are then evaluated and corrected, so that the final absolute viscosity data can be used. Copyright © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Regional Innovation Systems describe the relations between actors, structures and infrastructures in a region in order to stimulate innovation and regional development. For these systems the collection and organization of information is crucial. In the present paper we investigate the possibilities to extract information from websites of companies. First we describe regional innovation systems and the information types that are necessary to create them. Then we discuss the possibilities of text mining and keyword extraction techniques to extract this information from company websites. Finally, we describe a small scale experiment in which keywords related to economic sectors and commodities are extracted from the websites of over 200 companies. This experiment shows what the main challenges are for information extraction from websites for regional innovation systems.

Waste generation is on an increase globally. Resources, on the other hand, are getting scarcer. As a consequence, the importance of waste management is also constantly increasing. This is particularly applicable for the policies as well. Waste management is used in companies within the manufacturing industry with the objective of fulfilling legal requirements. Active waste management can however be used to contribute to the company revenues extensively. The Hochschule Hannover, in cooperation with JPM Silicon GmbH, has developed a process that achieves this goal at low costs. The use of the process in a silicon-processing company has resulted in a revenue contribution amounting of ten percent.

The control of mastitis in herds affected by cow-associated microorganisms should be based on prophylactic means to reduce the new infection rate. In the cases of Streptococcus (Sc.) agalactiae and Sc. canis, control is aimed towards eradication of these pathogens on herd level, while the prevalence and, with that, the new infection by Staphylococcus (S.) aureus should be lowered to a minimum. When dealing with infections by S. aureus on herd level, usually extensive culling of infected animals and therapies to eliminate existing infections may be avoided, as long as the measures to control new infections are set into practice thoroughly. Of those, the most important ones are identifying infected animals, separating them from the uninfected ones, observing a corresponding hygiene at milking, disinfecting the teats after milking with accredited products and disinfecting clusters between milking. Except for surveys after appliance, no studies regarding the efficiency of S. aureus vaccines have been performed so far. When dealing with herd problems due to Sc. agalactiae, a similar approach as with S. aureus in order to reduce the new infection rate is recommended. However, this pathogen spreads more quickly than the other one, and so it is essential to reduce the control phase to a minimum. So, after identifying infected animals, a decision for therapy or culling must be made subsequently. If therapy fails, animals should leave the farm at once. © M. & H. Schaper GmbH & Co.

Word clouds are used for the visual representation of texts. The font size and color of a word show its importance, and the position of a word in the cloud can be arbitrary or re-ect its relation to other words. In this paper, we present a tool that generates concept clouds from German company websites. The main idea of the visualization is to show the overall work and main interests of companies in a detailed information cloud based solely on their own web page. The concepts are taken from the STW Thesaurus of Economics. The colors of the concepts show the categories of the concepts in the thesaurus while the cloud layout is organized by semantic proximity of the concepts. To compute the similarity between concepts we use the semantic representation that is generated from DeWaC corpus. The distributional similarity is fundamentally diffierent from the co-occurrence statistics which often used to generate word clouds. © 2015 ACM.
