Das gute Recht auf Bildung
(2019)
Deutschland hat sich mit der Inkraftsetzung der UN-Behindertenrechtskonvention (BRK) als deutschem Recht ab dem 26. März 2009 unter anderem dazu verpflichtet, ein Bildungssystem zu verwirklichen, an dem Menschen mit Behinderung vollständig und gleichberechtigt teilhaben können. Darin ausdrücklich inbegriffen sind Angebote für Erwachsenenbildung und lebenslanges Lernen. „Die Vertragsstaaten stellen sicher, dass Menschen mit Behinderungen ohne Diskriminierung und gleichberechtigt mit anderen Zugang zu allgemeiner ...

On the Influence of Microstructure on the Corrosion Behavior of Fe–Mn–Al–Ni Shape Memory Alloy in 5.0 wt% NaCl Solution
(2020-10-03)
Herein the corrosion behavior of Fe–Mn–Al–Ni shape memory alloys characterized by different microstructures in a 5.0 wt% NaCl solution is investigated. Open circuit potential and potentiodynamic polarisation tests are conducted. Generally, Fe–Mn–Al–Ni shows corrosion properties being similar to pure iron. However, the polarization curves of single crystals indicate the presence of an unstable passive system. The corrosion damage is analyzed by means of optical microscopy and electron microscopy. It is revealed that ...

Investigation of residual stresses in polypropylene using hot plate welding
(2020-08-05)
During the cooling process of the molten material, residual stresses appear because the reduced volume of the cooled material cannot fully fill the space formerly occupied by the molten material. The morphology in and around the weld is formed by different factors depending on the material and process parameters. Different morphological structures relate to different mechanical properties. The process parameters and the welding results including morphology and residual stress are linked together. In this article, ...

Las tradiciones discursivas, la pragmalingüística y la lingüística del discurso
(2017)
El concepto de tradición discursiva desarrollado por la lingüística románica es central para una lingüística de enfoque cultural. Este concepto se basa en el modelo coseriano de la competencia lingüística, del cual se deduce la definición de las tradiciones discursivas. Una cuestión central de la lingüística con enfoque cultural es saber según qué principios, reglas y tradiciones se rigen los hablantes al realizar tareas comunicativas. El modelo de Coseriu abarca la sistematicidad lingüística de estas reglas y ...

Using Grass Cuttings from Sports Fields for Anaerobic Digestion and Combustion
(2017-03-18)
Sports fields provide a recreation space for citizens, but also generate grass biomass, which is cut weekly during the main seasons and therefore could be used in energy generation (combustion or anaerobic digestion). To evaluate the technical suitability of the grass cuttings, silage was produced from four sports fields during one vegetation period and investigated for relevant properties. Potential methane yield was determined with batch tests. Mean methane yield was 291.86 lN·kg−1 VSadded (VS, volatile solid). ...

Effects of three leafy vegetables on the growth performance of Giant African Snail Achatina (Lissachatina) fulica
(2019-06-07)
This present research was performed to evaluate the effects of three leafy vegetable diets [bitter leaf (Vernonia amygdalina), fluted pumpkin leaf (Telfairia occidentalis) and pawpaw leaf (Carica papaya)] on the growth performance of Giant African Snail (Achatina fulica). A total of ninety (90) A. fulica were used for the study. Thirty (30) snails each were subjected to three different dietary treatments in three replicates of 10 snails per replicate and fed with the fresh leaves of these vegetables over a period of ...

Urban Agriculture Oriented towards Self-Supply, Social and Commercial Purpose: A Typology
(2016-08-17)
Urban agriculture, a dynamic multifunctional phenomenon, affects the spatial diversification of urban land use, its valorization and its governance. Literature acknowledges its contribution to the development of sustainable cities. The dimension and extent of this contribution depends significantly on the particular form and function of urban agriculture. However, the complexity of interests and dimensions is insufficiently covered by theory. This paper proposes a typology for urban agriculture, supporting both theory ...

Consumer insights that drive value creation opportunities in the Indonesian domestic apple supply chain
(2019-07-10)
Agrifood chains that are based on the values defined by end consumers are able to secure a competitive edge over other chains, but securing that competitive edge requires a thorough understanding of the consumers and their value preferences. This study was conducted with a view to understanding domestic apple consumers in Malang, Indonesia, and using that information to guide the opportunities for domestic apple supply chain development in Indonesia. Data were collected through an intercept survey of 200 apple ...

High-precision force sensing using a single trapped ion
(2016-06-16)
We introduce quantum sensing schemes for measuring very weak forces with a single trapped ion. They use the spin-motional coupling induced by the laser-ion interaction to transfer the relevant force information to the spin-degree of freedom. Therefore, the force estimation is carried out simply by observing the Ramsey-type oscillations of the ion spin states. Three quantum probes are considered, which are represented by systems obeying the Jaynes-Cummings, quantum Rabi (in 1D) and Jahn-Teller (in 2D) models. By using ...

Different forms of life satisfaction and their relation to affectivity
(2016-05-03)
Aims: The present study is aimed at studying the research question whether high satisfaction levels achieved through either (1) the fact that one's quality of life is truly satisfactory (i.e., stabilized life satisfaction) or through (2) adapting a more favorable perception of one's quality of life by lowering standards (i.e., resigned life satisfaction) are associated with different levels of positive affect (PA) and negative affect (NA) when compared to each other but also when compared to dissatisfied individuals.
