Bend Straightening of a Carbonitrided Gear Shaft – Consequences on Residual Stresses and Retained Austenite near the Surface
(2017-06-20)
Carbonitriding of shafts in drive technology is strongly connected with distortion. Bend straightening is an important process step in order to eliminate distortion without removing the hardened surface layer. As shown in several investigations, even for simple part geometries, bending induced stresses and plastic deformations have a strong impact not only on the residual stress state but also on the microstructure after straightening. As gear shafts become increasingly filigree and complex in their geometry, the ...

Boxwood Borer Heterobostrychus brunneus (Coleoptera: Bostrichidae) Infesting Dried Cassava: A Current Record from Southern Ethiopia
(2017-01-27)
Insect specimens of adult beetles and larvae of 7–9 and 9–10 mm length, respectively were collected from infested dry cassava at two locations from multiple stores in southern Ethiopia. The specimens were identified as Heterobostrychus brunneus (Murray, 1867) commonly known as boxwood borer and auger beetle. The study presents a current record of H. brunneus in Ethiopia, particularly in the context of infesting food products. Additionally, a wide geographical distribution of the pest was reviewed and presented in ...

Weak and strong bi-material interfaces and their influence on propagating cracks in plane elastic structures
(2017-09-06)
The developing crack paths in heterogeneous structures are the result of the inhomogeneous state of stress. The latter stems from e.g. voids or inclusions in an elastic matrix, which are bonded either by strong or weak interfaces. Besides the stiffness of an inclusion, the kind of interface has a decisive influence on the state of stress and therefore on propagating cracks. It is experimentally proven that cracks tend to grow towards regions with lower stiffness (Tilbrook et al., 2006; Judt et al., 2015), therefore ...

Outsmarting the MNCs by fitting strategic manoeuvres to national framing: evidence from India
(National University of Political Studies and Public Administration (SNSPA), Faculty of ManagementTritonic, 2017)
This paper focuses on how Indian home-grown companies captured MNCs market in India with the help of strategic maneuvering and understanding their own capabilities. Seizing the framework of Porter’s National Diamond this research follows a caselet approach for illustrating these strategies. The study’s originality springs from understanding changes in demand pattern brought by home-grown companies in the Indian market. A key implication of this paper is that the demand conditions and firm strategy (by means of targeting ...

Post-crises response strategies: a combined model to manage brand crises
(National University of Political Studies and Public Administration (SNSPA), Faculty of ManagementTritonic, 2017)
Brand crises negatively affect customers’ perception of the brand’s ability to deliver expected functional or symbolic benefits. Post-crisis response strategies should be implemented to restore brand trust and diminish the effect of reputational threat, since these strategies act as critical determinants of the actual impact of the crisis on consumers’ evaluations and consequently on repurchase intentions. A categorization of the nature of the crisis, distinguishing between ‘performance-related’ and ‘values-related’ ...

How digitalization changes the internationalization of entrepreneurial firms: theoretical considerations and empirical evidence
(National University of Political Studies and Public Administration (SNSPA), Faculty of ManagementTritonic, 2017)
The internationalization of firms is predominantly analyzed and explained considering observations from a pre-digital business environment. Thus, the applicability to digital ways of doing business needs to be challenged. Recent literature on the internationalization of digital firms attempts to adapt existing international business literature to the digital market. However, these studies consider internet-based companies predominantly as a homogeneous group. It is a popular opinion, that digital internationalization ...

Controlled magnetic devices in power electronic applications
(IEEE, 2017)
Almost all power electronic converters require magnetic devices and some properties of the converters can be controlled with magnetics. New magnetic materials enable implementation of magnetic control of converters also in high switching frequency applications. The presented paper gives an overview about controllability of magnetic devices in theory and practice, simulation approaches and examples. The focus is on electrically controllable magnetic devices. This means that an additional control winding is wound on ...

Zwischen Reichtum und Prekarität. Welchen Wohlfahrtsstaat benötigen Künstler_innen?
(2017-08)
Die Veranstaltung fand am 27. und 28. Juni 2017 in der Kunsthochschule Kassel sowie in der Evangelischen Studierendengemeinde in Kassel statt. Vor Ihnen liegt nun die Dokumentation dieser Tagung, die dazu beitragen soll, die wichtigsten Eckpunkte festzuhalten und die Diskussion um die Frage der sozialen Absicherung von Künstler_innen in eine hoffentlich breiter werdende Öffentlichkeit zu tragen. Die Dokumentation beruht auf Vortragsmanuskripten, berichthaften Protokollen, die die Mitarbeiter des Fachgebietes „Politisches ...

Die Fragilität des Körpers
(Institut für Freizeitwissenschaft und Kulturarbeit (IFKA) e.V. an der Hochschule Bremen, 2017)
Schwere Krankheiten, Beeinträchtigungen und Behinderungen werden im öffentlichen wie auch fachlichen Diskurs um Sterbehilfe immer wieder als Begründung benutzt, für die Ermöglichung des ärztlich assistierten Suizids zu plädieren – mit dem Argument, ein entsprechendes Leben sei letztlich „nicht menschenwürdig“. Doch Menschenwürde hat jeder Mensch, bzw. jedem Menschen wird Menschenwürde in den internationalen Menschenrechtsabkommen zugesprochen. Die Achtung der Menschenwürde hat den Stellenwert einer unhintergehbaren ...
