An extended constitutive model for nonlinear reversible ferromagnetic behaviour under magnetomechanical multiaxial loading conditions
(2017-02-01)
A constitutive modelling of ferromagnetic materials under combined magnetomechanical multiaxial loading with different boundary conditions and a finite element implementation are presented. The phenomenologically motivated model is capable of predicting magnetisation, strain, and stress and is thus suitable, e.g., for applications in multiferroic composites. The approach covers a reversible nonlinear behaviour as it is observed, e.g., in cobalt ferrite and other soft magnetic alloys. Various examples demonstrate the ...

Auf dem Weg zum Königtum
(2017)
Wie kann gerechte Herrschaft aussehen? Eine Frage, die vor einigen Jahren wohl nur einige politische Theoretikerinnen und Moralphilosophen beschäftigt hat, treibt nach dem Ende des Jahres 2016 mehr oder minder ausgesprochen viele Menschen um. Selbstverständliche Ordnungen der Gesellschaft scheinen angefragt. Politiker geraten an die Regierung, deren offensichtliches Machtstreben das Amt suspekt werden lässt. Die Frage nach der Macht, ihren Ordnungen und auch den Persönlichkeiten, die sie erlangen, ist virulent wie ...

(Stereotype) Männlichkeit und Weiblichkeit im Pressetext
(2017)
Der Beitrag untersucht die sprachliche Konstruktion von Geschlechtsspezifik anhand des Lexempaares weiblich und männlich in bundesdeutschen Pressetexten des Jahres 2013. Neben der konstruktivistischen Prämisse, die davon ausgeht, dass die menschliche Wahrnehmung der Wirklichkeit zu einem Großteil durch Sprache geformt wird, liegt das Konzept doing gender zugrunde, wonach Geschlecht (gender) nicht etwas ist, das man hat, sondern etwas, das man tut. Dem (pressetextlichen) Sprachgebrauch kommt dabei eine entscheidende ...

Grundsatzfragen der Abwärmenutzung
(2017-04)
In der Diskussion zum Thema Energieeffizienz wird regelmäßig über Abwärmenutzungstechnologien (AbWT) wie Sorptionskältemaschinen, Organic-Rankine-Cycle-Prozesse (ORC) oder Wärmepumpen diskutiert. Diese sollen eine praktikable Nutzung von Abwärme ermöglichen. Im Sinne eines Plug & Play Systems erfolgt die Ankopplung an eine Abwärmequelle und eine andere Nutzenergieform wie Strom, Kälte oder Hochtemperaturwärme kann an geeigneter Stelle wieder in den Prozess integriert werden. Doch wie lassen sich Abwärmequellen und ...

Individual Appropriation of Learning Management Systems — Antecedents and Consequences
(2017-01-10)
IT support in the learning process constitutes a key factor for the success of innovative teaching/learning scenarios. To ensure learning success in innovative teaching/learning scenarios, learners need to faithfully apply learning management systems (LMS). However, we lack theoretical insights into which factors affect whether they do so. To help solve this issue, we first used adaptive structuration theory to identify antecedents and consequences regarding faithful LMS appropriation and embed them into a theoretical ...

Adoption of Organic Farming as an Opportunity for Syrian Farmers of Fresh Fruit and Vegetables: An Application of the Theory of Planned Behaviour and Structural Equation Modelling
(2017-11-04)
Exporting organic fresh fruit and vegetables (FFV) to the European Union could represent a great opportunity for Syrian farmers and exporters. Yet, the organic sector in Syria is comparatively young and only a very small area of FFV is organically managed. To date, little is known about Syrian farmers’ attitudes towards organic FFV production. Therefore, the aim of this study was to explore the intentions and attitudes of Syrian farmers of FFV towards organic farming and how likely they are to convert their farms to ...

Phenotypic diversity, major genes and production potential of local chickens and guinea fowl in Tamale, northern Ghana
(2017-06-26)
Objective:
Our study provides information on phenotypes of local chickens and guinea fowl and their body measures as well as on major genes in local chickens in northern Ghana.
Methods:
Qualitative and morphometric traits were recorded on 788 local chickens and 394 guinea fowl in urban households in Tamale, Ghana.
Results:
The results showed considerable variation of color traits and numerous major genes in local chickens, while color variations and related genotypes in guinea fowl were limited. In local chickens, ...

The Dark Triad and the PID-5 Maladaptive Personality Traits: Accuracy, Confidence and Response Bias in Judgments of Veracity
(2017-09-21)
The Dark Triad traits—narcissism, Machiavellianism and psychopathy—have been found to be associated with intra- or interpersonal deception production frequency. This cross-sectional study (N = 207) investigated if the Dark Triad traits are also associated with deception detection accuracy, as implicated by the recent conception of a deception-general ability. To investigate associations between maladaptive personality space and deception, the PID-5 maladaptive personality traits were included to investigate if besides ...

Fat-containing cells are eliminated during Dictyostelium development
(2017-09-15)
Triacylglycerol is a universal storage molecule for metabolic energy in living organisms. However, Dictyostelium amoebae, that have accumulated storage fat from added fatty acids do not progress through the starvation period preceding the development of the durable spore. Mutants deficient in genes of fat metabolism, such as fcsA, encoding a fatty acid activating enzyme, or dgat1 and dgat2, specifying proteins that synthesize triacylglycerol, strongly increase their chances to contribute to the spore fraction of the ...

Aphyllophoroid fungi in insular woodlands of eastern Ukraine
(2017-12-22)
Background
Fungi play crucial roles in ecosystems and are among the species-richest organism groups on Earth. However, knowledge on their occurrence lags behind the data for animals and plants. Recent analyses of fungal occurrence data from Western, Central and Northern Europe provided important insights into response of fungi to global warming. The consequences of the global changes for biodiversity on a larger geographical scale are not yet understood. Landscapes of Eastern Europe and particularly of eastern ...
