Methoden zur Auslegung einer Mensch-Roboter-Kooperation
(2019)
Durch eine neue Generation von Robotern werden Maschinen, die bisher hinter einem Schutzzaun arbeiteten, in den Arbeitsraum eines Industriewerkers versetzt. In der Mensch-Roboter-Kooperation (MRK) werden Schutzzäune durch Sensorik ersetzt, die sich häufig am Roboter befindet. Die neuartigen Roboter sind tendenziell kleiner und leichter als ihre konventionellen Artgenossen, dürfen ihre Tätigkeiten jedoch in nächster Nähe zu einem Menschen ausüben. Wie wirkt sich dies auf den Industriearbeiter aus?
Genau diese Frage ...

BamB facilitates folding of outer membrane protein A (OmpA) via interactions of its β-propeller with the membrane surface and via a conformation change induced by phosphatidylglycerol
(2019-10-17)
A sufficient folding and insertion of OMPs into the OM of Gram-negative bacteria requires the conserved β-barrel assembly machinery (BAM) complex. The present thesis concerns the structural properties and folding behavior of the lipoprotein BamB and describes its relevance in the synchronized mechanism of membrane insertion and folding of the β-barrel protein OmpA. Furthermore, specific binding sites in BamB involved in the interaction to the lipid membrane or the periplasmic domain of BamA (PD-BamA) were identified ...

Donor-stabilisierte Bisphosphanyl-Tetrylene
(2018-09)
Gegenstand dieser Arbeit war die Untersuchung der Darstellbarkeit Bisphosphanyl-substituierter, schwerer Tetrylene mit 1,1‘-Ferrocenylenrückgrat war. Die Synthese freier, stabiler Bisphosphanyl-Tetrylene gelang aufgrund sterischer und elektronischer Gründe nicht, jedoch konnten NHC-stabilisierte Addukte (Si, Sn, Pb), intermolekular stabilisierte, dimere Donor-Akzeptor Addukte (Sn, Pb) und intramolekular stabilisierte Donor-Akzeptor-Addukte (Pb) isoliert, charakterisiert und deren Reaktionsverhalten untersucht werden.

Responsibility and prosocial behavior - Experimental evidence on charitable donations by individuals and group representatives
(2020-11-13)
In this paper we present a lab-in-the-field experiment with a large and diverse sample to compare charitable donations when individuals decide for themselves only and when they decide as a group representative. In contrast to the previous literature, we find that individuals make greater charitable contributions when they decide as a group representative than when they decide alone. This result demonstrates that being responsible for a group does not always lead to more selfish behavior.

Strom – fit für die Zukunft?
(Görich & Weiershäuser, 2019-04-02)
Das 2008 in gedruckter Form und als pdf veröffentlichte Buch liegt hier in neuester Überarbeitung vom 02.04.2019 vor.
Es stellt mögliche Komponenten eines "integrierten Balancing-Management" vor, das die Sekundärregelung unter Einbeziehung aller Flexibilitätsoptionen, insbesondere der gesamten Verbrauchsseite, ressourcenoptimiert realisieren könnte. Mehrere denkbare Instrumente für das verteilte Handling von (drohenden) Überlastungs- und Notfallsituationen (auch langdauernde extreme Dunkelflauten) werden beschrieben.

A Paradigm Shift in Water Quality Governance in a Transitional Context: A Critical Study about the Empowerment of Local Governance in Georgia
(2018-01-01)
The management of water quality is an important part of natural resource governance. Assurance of water quality therefore requires formulation of the regulatory framework and institutional process. Water quality-related problems and their management are mainly recognized as local responsibilities in Integrated Water Resources Management (IWRM). The politics of environmental policy-making should consider the political economic dynamics and socio-ecological patterns. Decentralization by providing more power to the local ...

Nutrition Transition and Traditional Food Cultural Changes in Sri Lanka during Colonization and Post-Colonization
(2018-07-13)
Sri Lanka was a colony of the Portuguese, Dutch, and British. The simplification of Sri Lankan food culture can be seen most clearly today, including how the diet has been changed in the last 400 years since the colonial occupation began. Therefore, greater efforts must be made to uncover the colonial forces that have undermined food security and health in Sri Lanka. Also traditional eating habits, which are associated with countless health benefits, have been gradually replaced by the globalized food system of ...

Sustainability Tensions in Supply Chains: A Case Study of Paradoxes and Their Management
(2018-02-06)
The comprehensive coverage of sustainability issues in a supply chain incurs goal conflicts—i.e., sustainability tensions—and is often limited by market characteristics, such as the availability of sustainable materials and services. While the mainstream business is prioritizing economic goals, a number of entrepreneurs are trying to move forward to more sustainable business practices for their own company and their supply chain. Fairphone represents such a case in the electronics industry, which is openly communicating ...

Farm and farmer capital foster adoption of improved quality agrochemical inputs in the cotton-wheat zone of the Punjab, Pakistan
(2019-12-23)
Adoption of yield-enhancing agricultural inputs fosters agricultural intensification in low-income countries. In Pakistan, initial adoption of agrochemicals is already widespread; the low quality of much of the inputs contributes to severe health, environmental and enduring pest problems, however. While the positive influence of farm capital and farmer capital on initial adoption is well documented, the adoption of improved quality inputs is little researched. We reduce the knowledge gap investigating smallholder ...

Das NetworkParser-Framework
(2019-03-10)
Meine Dissertation, die im Fachbereich Elektrotechnik/Informatik in Kassel eingereicht wurde, hat das Ziel ein Tool zur Verfügung zu stellen, um den Entwickler bei der Entwicklung eines Programms in jedem Entwicklungsschritt zu unterstützen. Der komplette Ablauf von Story Driven Modeling wird dabei unterstützt. Das Tool soll so intuitiv bedienbar sein, dass Programmieranfänger damit arbeiten können und die Techniken erlernen können. Es ist gelungen ein kompaktes Tool für den kompletten SDM-Prozess zu schaffen, welches ...
