Eine Kampagne, die darauf ausgerichtet ist, die Bevölkerung auf sozialer Ebene aufzurufen, Impf-Skeptiker aufzuklären und von Impfungen zu überzeugen. Anhand von offiziellen Statistiken, die optisch ansprechend aufbereitet wurden, werden die Menschen über Krankheiten und dazu gehörige Risiken informiert. Des Weiteren wird der Impferfolg grafisch dokumentiert und leicht verständlich präsentiert, ohne Fakten auszulassen.
Durch eine Serie Plakate verschiedener Formate werden die Betrachter animiert, die Homepage impfen.info aufzusuchen und das reichhaltige Informationsangebot zu nutzen.
Mithilfe einer amüsanten Postkartenreihe wird die Verbreitung von Krankheitserregern simuliert und postalisch in die Haushalte der Impfgegner- und Skeptiker gebracht, um zu verdeutlichen, wie rasant Viren sich verbreiten und wie wichtig es ist, sich und seine Lieben zu schützen.
(K)eine Opposition: Die Wahlkampfgestaltung der SPD und CDU von 1945—1990 im historischen Kontext
(2021)
Im Zentrum des Buches stehen die beiden Volksparteien CDU und SPD, die sich als gegensätzliche, gar verfeindete Parteien startend, gegenwärtig in ihren visuellen und inhaltlichen Identitäten immer unerkenntlicher vermischen. Das Buch geht dem Ursprung dieser Vermischung auf die Spur und untersucht inwiefern sich die visuellen Identitäten der beiden Parteien zwischen 1945 und 1990 in Form der Gestaltung nach außen aneinander angeglichen haben und wer wann federführend in der Gestaltung war.
Beginnend 1945 in der »Stunde Null« führt das Buch in den einzelnen Kapiteln durch das Zeitgeschehen der Bundesrepublik bis ins Jahr 1990. Der historische Querschnitt beleuchtet dabei das gesellschaftspolitische Zeitgeschehen, das den Wahlkämpfen zugrunde liegt. Dabei stehen die politischen Wahlplakate im Fokus der Untersuchung: SPD und CDU — (k)eine gestalterische Opposition?
Nach einer wahren Begebenheit nimmt der Kurzfilm den Zuschauer mit in das Erlebnis zweier Kinder eines Luftangriffes während des Zweiten Weltkriegs: "Es ist 1944, in Deutschland wütet der Zweite Weltkrieg. Horst und Elli erledigen gerade mit ihrer Tante die Einkäufe, als plötzlich die Sirenen aufheulen. Die Drei rennen auf schnellstem Weg zurück zum Dorf, um sich in den sicheren Luftschutzkeller zu flüchten. Doch in der Hektik werden die Kinder von ihrer Tante getrennt und als die ersten Bomben fallen, sind die Beiden noch lange nicht am Bunker angelangt. Geistesgegenwärtig reagiert Horst und rettet so ihrer beider Leben. Bevor weitere Bomben einschlagen, erreichen die Kinder endlich den sicheren Luftschutzkeller."

Background:
Additional stabilization of the “comma sign” in anterosuperior rotator cuff repair has been proposed to provide biomechanical benefits regarding stability of the repair.
Purpose:
This in vitro investigation aimed to investigate the influence of a comma sign–directed reconstruction technique for anterosuperior rotator cuff tears on the primary stability of the subscapularis tendon repair.
Study Design:
Controlled laboratory study.
Methods:
A total of 18 fresh-frozen cadaveric shoulders were used in this study. Anterosuperior rotator cuff tears (complete full-thickness tear of the supraspinatus and subscapularis tendons) were created, and supraspinatus repair was performed with a standard suture bridge technique. The subscapularis was repaired with either a (1) single-row or (2) comma sign technique. A high-resolution 3D camera system was used to analyze 3-mm and 5-mm gap formation at the subscapularis tendon-bone interface upon incremental cyclic loading. Moreover, the ultimate failure load of the repair was recorded. A Mann-Whitney test was used to assess significant differences between the 2 groups.
Results:
The comma sign repair withstood significantly more loading cycles than the single-row repair until 3-mm and 5-mm gap formation occurred (P≤ .047). The ultimate failure load did not reveal any significant differences when the 2 techniques were compared (P = .596).
Conclusion:
The results of this study show that additional stabilization of the comma sign enhanced the primary stability of subscapularis tendon repair in anterosuperior rotator cuff tears. Although this stabilization did not seem to influence the ultimate failure load, it effectively decreased the micromotion at the tendon-bone interface during cyclic loading.
Clinical Relevance:
The proposed technique for stabilization of the comma sign has shown superior biomechanical properties in comparison with a single-row repair and might thus improve tendon healing. Further clinical research will be necessary to determine its influence on the functional outcome.
Wind energy represents the dominant share of renewable energies. The rotor blades of a wind turbine are typically made from composite material, which withstands high forces during rotation. The huge dimensions of the rotor blades complicate the inspection processes in manufacturing. The automation of inspection processes has a great potential to increase the overall productivity and to create a consistent reliable database for each individual rotor blade. The focus of this paper is set on the process of rotor blade inspection automation by utilizing an autonomous mobile manipulator. The main innovations include a novel path planning strategy for zone-based navigation, which enables an intuitive right-hand or left-hand driving behavior in a shared human–robot workspace. In addition, we introduce a new method for surface orthogonal motion planning in connection with large-scale structures. An overall execution strategy controls the navigation and manipulation processes of the long-running inspection task. The implemented concepts are evaluated in simulation and applied in a real-use case including the tip of a rotor blade form.
This paper introduces a new maritime search and rescue system based on S-band illumination harmonic radar (HR). Passive and active tags have been developed and tested while attached to life jackets and a small boat. In this demonstration test carried out on the Baltic Sea, the system was able to detect and range the active tags up to a distance of 5800 m using an illumination signal transmit-power of 100 W. Special attention is given to the development, performance, and conceptual differences between passive and active tags used in the system. Guidelines for achieving a high HR dynamic range, including a system components description, are given and a comparison with other HR systems is performed. System integration with a commercial maritime X-band navigation radar is shown to demonstrate a solution for rapid search and rescue response and quick localization.
Quantitative nuclear magnetic resonance (qNMR) is considered as a powerful tool for multicomponent mixture analysis as well as for the purity determination of single compounds. Special attention is currently paid to the training of operators and study directors involved in qNMR testing. To assure that only qualified personnel are used for sample preparation at our GxP-accredited laboratory, weighing test was proposed. Sixteen participants performed six-fold weighing of the binary mixture of dibutylated hydroxytoluene (BHT) and 1,2,4,5-tetrachloro-3-nitrobenzene (TCNB). To evaluate the quality of data analysis, all spectra were evaluated manually by a qNMR expert and using in-house developed automated routine. The results revealed that mean values are comparable and both evaluation approaches are free of systematic error. However, automated evaluation resulted in an approximately 20% increase in precision. The same findings were revealed for qNMR analysis of 32 compounds used in pharmaceutical industry. Weighing test by six-fold determination in binary mixtures and automated qNMR methodology can be recommended as efficient tools for evaluating staff proficiency. The automated qNMR method significantly increases throughput and precision of qNMR for routine measurements and extends application scope of qNMR.
