The present paper shows the current state of a feasibility study of the University of Applied Sciences Esslingen. The intention of this study is the conversion of a model-turbine into a turboshaft-engine for variable applications, with as few as possible modifications. The shaft power of the engine is estimated on 20 kW at least. It is intended to use a recuperator to augment its efficiency. After a general introduction possible applications are discussed and the previous design-process is explained: Subsequent to the concept-phase cycle parameters were calculated and the power turbine was designed and manufactured. At present turbine tests are running. The recuperator is of counter flow type. To shorten the flow path it is mounted directly around the combustor. Currently different variations are being designed which will be optimised. The pressure loss within the exhaust manifold between power turbine and recuperator has already been reduced by simulations and tests. This will be minimised through application of a genetic optimisation software.

The family-friendly university audit (“audit familiengerechte hochschule”) is studied. The audit is available to German universities in order to support a familyfriendly working environment. Practices of an auditor coordinating several workshops for rectorate, HR department and functionaries, as well as representatives of all university groups are considered. The experience of the auditing at the University of Applied Sciences – Public Administration and Finance, Ludwigsburg is analyzed.

Nothing has highlighted the importance of digital teaching and learning opportunities more obviously than the Corona pandemic. This book therefore focuses on multicodal or multimedia digital teaching. The authors examine it from various perspectives and make suggestions for successful didactic implementation. In addition to general topics of digital teaching, they devote particular attention to visual literacy, which plays a special role in multimedia teaching. Criticism of teachers' lack of digital skills alone will not lead to success. Therefore, ways are shown here how these skills can be acquired. Tips and concrete examples for suitable apps, serious games, and online training courses round off the volume. Christina Maria Ersch is a staff member/DaF coordinator at the International Office of the University of Applied Sciences Mainz and lecturer at the University of Mainz. Her research interests lie in (university) didactics, especially in the implementation of competence orientation and digitalization of teaching of teaching, intercultural communication, and the influence of emotions in of emotions in (foreign language) teaching. Dr. Marion Grein is head of the Master's program DaF/DaZ at the the University of Mainz. Her work focuses on language teaching research (neurodidactics), intercultural communication, and digital teaching.

Norwegian and Scandinavian languages in general have grown quite popular among Polish students in recent years and more and more Polish universities are trying to offer Bachelor’s and even Master’s programmes in a Scandinavian language. Based on experience as a teacher of a Norwegian grammar course at the University of Szczecin and as a teacher of grammar at the Inland Norway University of Applied Sciences which in 2016/2017 hosted around twenty Erasmus+ students from Szczecin, some of the challenges for Polish students of academic Norwegian will be reflected upon, as well as some of the challenges for a teacher of Norwegian who has very little knowledge of Polish. The main purpose of this paper will be to argue for the importance of grammar skills in language education and especially in language teacher education. This study is a contribution to the Educational Role of Language network.

Introductory Phase

This is a report on the initial efforts made to develop phenomenological and hermeneutical methods for didactical use and epistemological research in communicology and translatology. The following analysis deals with a face-to-faceinteraction workshop that took place at the University of Applied Sciences Cologne in January 2012. The primary goal of this workshop was to establish whether or not an adaptation of the Husserlian phenomenological method could be applied within the framework of role plays, i.e., to see to what extent the phenomenological method makes it possible to observe oneself reflectively while actively participating in role plays. In toto, 14 English and German speaking participants took part in different role plays simulating the job-interview process. For this purpose the phenomenological and hermeneutical methods were explicated in an introductory phase and – at least at a rudimentary level – employed in the role plays. During the role plays, the primary tool employed to disclose verbal, para-verbal and non-verbal phenomena used in communication was the phenomenological method. After the role plays, a hermeneutical analysis was done in one selected group. The participants involved were asked to talk about the experiences they made during the role play; this was done while watching a video of the role plays, and it was designed to access the meaning of various verbal, para-verbal and non-verbal phenomena. Especially the comparison of their feelings, thoughts and perceptions with those of other participants was quite informative.

Alcohol Reduction

Over the last decade, several distinct research groups tested possible uses of membrane contactors for the wine industry, notably for the management of dissolved gases in wines, adjustment of the CO2 concentration while reducing the O2 concentration at the same time. Other experiments were done with partial alcohol reduction and addition of N2 to wines. The contactor's heart is its Liqui-Cel™ membrane where the two separate circuits meet. The membrane's hydrophobic characteristics allows a liquid to get in contact with a gas, without dispersing into it. The directions that these gases take through the membrane depend on their partial pressure differences within the two circuits. However, other factors need to be considered to determine exact exchange rates for each target gas. The present article describes the new membrane contactor prototype that was co-developed by the University of applied Sciences and Arts, Viticulture and Enology at Changins, Switzerland, and the School of Engineering and Architecture at Fribourg, Switzerland. The prototype was designed for small scale operations. Flow rates, temperatures and internal pressures can be instantly measured and graphically visualized. Also, O2 concentrations are measured inside the liquid. CO2 concentrations in the liquid can be measured with a device that is connected to the liquid circuit through a bypass after the membranes.

In this paper the wind tunnel at the University of Applied Sciences Stralsund and few construction details as well as the calibration of the nozzle are presented. Furthermore some approaches to visualization and measurement of velocity fields of a simple body of vehicle are shown. The wake structure behind of simple car models was investigated experimentally using Particle Image Velocimetry (PIV). Furthermore the visualization of flow field by the fog probe systems supports the evaluation of the flow and drag behavior.

Thanks to easier operability and a growing range of functions, open source products are increasingly being used in teaching GIS to students of various course programs. The elaboration of such courses poses the challenge of taking into account different study paths, allowing for student autonomy (e-learning), and choosing the right software. The article suggests answers to these questions by presenting the classes offered at the University of Applied Sciences in Deggendorf and the University of Passau since winter 2010/11 as well as ideas for future course offers.

The paper measures the soft skills needs of companies and industry to technical oriented academic graduates, especially coming from IT course programs like business informatics, computer science, or information management. Therefore, between March and September 2010, two groups of researchers at the University of Applied Sciences (UAS) Technikum Vienna analyzed job profiles and the intended denotation of certain keywords. Primarily, one group worked on the statistical content analysis of job offers which could be found in Austrian newspapers or were provided by online job platforms. The other group developed a survey to be sent to several companies in Austria and was addressed to human resources departments. The paper explains the evaluation results in details and discusses its necessary implication on academic curriculum design.
