Nutritional Comparison of White and Red Coccinia Abyssinica (Lam.) Cong. Accessions: An Under-Utilised Edible Tuber of the Ethiopian Highlands
(2017-08-22)
Anchote (Coccinia abyssinica) is an indigenous tuber crop of the Ethiopian Highlands. It is popular in the western Oromia Region of the country. Apart from food, the crop is also used in traditional medicine. Anchote tubers possess two variations in its tissue colour, red and white. In this study, a small market survey and a nutritional comparison of red and white anchote were conducted. White tissue anchote seems to be more popular, due to its soft texture and ease of cooking. However, the red variant was considered ...

Preparation and Molecular Structure of a Cyclopentyl-Substituted Cage Hexasilsesquioxane T6 (T = cyclopentyl-SiO1.5) Starting from the Corresponding Silanetriol
(2017-10-04)
Cyclopentyl substituted silanetriol can be prepared and isolated. Its condensation yields the corresponding disiloxanetetrol as a primary condensation product. Further condensation leads to the hexameric polyhedral silsesquioxane cage T6. The latter has been mentioned in the literature before however, lacking structural data. All compounds have been characterized with multinuclear NMR spectroscopy and, in addition, the molecular structures have been determined in the case of the disiloxanetetrol and the hexasilsesquioxane ...

Deiktika in altspanischen Texten
(2010-09)
La présente contribution montre à l’exemple de déictiques dans des textes de l’espagnol médiéval comment les fonctions des langues particulières et les traditions discursives sont imbriquées les unes dans les autres. Concernant les déictiques, nous sommes d’avis que la polyfonctionnalité, c’est-à-dire la coexistence synchronique de fonctions indexicales et non-indexicales, est une caractéristique des déictiques en espagnol médiéval (et des langues romanes en général). Afin d’établir des relations précises et systématiques ...

Tipping Versus Cooperating to Supply a Public Good
(2017-02-17)
In some important multiplayer situations, such as efforts to supply a global public good, players can choose the game they want to play. In this paper we conduct an experimental test of the decision by a group with fixed membership, playing over a finite number of periods, to choose between a “tipping” game, in which every player wants to contribute to the public good provided enough other players contribute, and a prisoners’ dilemma, the classic cooperation game. In the prisoners’ dilemma, the first best outcome is ...

Optimal energy supply structures for industrial food processing sites in different countries considering energy transitions
(2017-05-10)
This study focuses on analysing the most energy efficient utility system supply structure in terms of carbon emissions, primary energy efficiency and energy costs. In the German food processing industry, the state-of-the-art technologies in the utility supply structure are a gas fired steam boiler for steam generation and ammonia chillers for chilled water generation. Low investment costs and its durability are attractive for industrial production sites. But, given the ongoing energy transition to renewable energy, ...

The relationships of character strengths with coping, work-related stress, and job satisfaction
(2015)
Personality traits have often been highlighted to relate to how people cope with stressful events. The present paper focuses on character strengths as positive personality traits and examines two basic assumptions that were derived from a core characteristic of character strengths (i.e., to determine how individuals deal with adversities): (1) character strengths correlate with coping and (2) buffer the effects of work-related stress on job satisfaction. Two different samples (i.e., a mixed sample representing various ...

Morphology-property-relationship of thermo-mechanically graded self-reinforced polypropylene composites
(2015-02-17)
In this paper the relationship between different composite morphologies and their mechanical properties is to be investigated. By manufacturing two different tape-based polypropylene composites in a compression moulding process, four varying degrees of compaction will be generated. The morphological structure is analyzed using confocal laser light microscopy and wet chemically etched specimen cross-sections. The etching process removes the amorphous phase in the polymer, making the macromolecular orientations and ...
