Diversification of maize-based intercropping systems in tropical rainforest agroecosystem of Nigeria: productivity, profitability and soil fertility
(2021-02-07)
Monocropping of maize is becoming unsustainable in the rainforest agroecosystem of Nigeria. This is due to the adverse impact of climate change such as increasing pests and disease infestations and erratic rainfall patterns coupled with underutilization of resources. Smallholder farmers in this tropical agroecosystems are in dire need of adaptive and resilient cropping systems to ensure food, nutrition, and livelihood security. Thus, this study aims to identify adaptive maize-based systems for the rainforest agroecology ...

Zur Entstehung der Halbtagsschule in Deutschland. Eine bildungspolitische und pädagogische Fehlentwicklung?
(2021)
Ziel der Arbeit ist den historischen Weg darzustellen, um damit einen offeneren und besseren Blick auf die Gegenwart zu bekommen, dass die Entstehung der Vormittagsschule zuerst an höheren und später auch an Volksschulen m. E. möglicherweise eine bildungspolitische und pädagogische Fehlentwicklung darstellte, die es heute aus pädagogischen, sozialpädagogischen aber auch wirtschaftlichen Gründen zu korrigieren gilt.

Die Politisch-Administrative Elite der BRD unter Angela Merkel (2005-2018)
(2021)
Diese Randauszählung wurde im Rahmen des Forschungsprojektes „Neue Eliten – etabliertes Personal? (Dis-)Kontinuitäten deutscher Ministerien in Systemtransformationen“ am Fachgebiet Public Management der Universität Kassel erstellt. Die hier präsentierten Tabellen und Abbildungen fassen die Ergebnisse deskriptiver Auswertungen der im Forschungsprojekt erhobenen Daten zur Politisch-Administrativen Elite in der BRD unter Bundeskanzlerin Merkel (bis März 2018) zusammen und veranschaulichen die Häufigkeitsverteilungen ...

ARQUITECTURA Y EVANGELIZACIÓN
(2021-10-23)
Bajo la perspectiva simbólica y la interpretación formulada desde planos sincréticos que aún se pueden identificar, los templos cristianos levantados entre los siglos XVI y XVII en el Cusco exponen bajo sus espacios, formas y elementos propios de la evangelización, connotaciones míticas y contenidos que los vinculan con los antiguos adoratorios Inkas sobre los cuales fueron construidos, testificando la vigencia de la cultura andina ancestral pese a los procesos de extirpación de idolatrías activados desde el ...

LO BARROCO Y LO MESTIZO
(2021-11-20)
En el marco histórico, cultural y religioso en el que surgió el estilo barroco, se hace referencia a sus expresiones en el Virreinato del Perú, en particular en Cusco y su región y a partir del siglo XVII.
Se exponen las características del "barroco mestizo" del Sur Andino – una expresión que destacó por su decoración con motivos de la flora y la fauna local plenos de simbolismo.

High temperature-stable InGaAs QDs for the monolithic integration in external-cavity surface-emitting lasers
(2021)
Optically pumped vertical external-cavity surface-emitting lasers (VECSELs), also called semiconductor disk lasers (SDLs), benefit from the flexibility and versatility of the semiconductor material. With a simple cavity layout, fundamental transverse mode operation with a circular output beam and high beam quality is possible. They have excellent heat-sink properties and only require inexpensive multimode diode lasers for pumping. The complete VECSEL structure is only a few micrometers thick which leads to a strong ...

On the reliability of residual stress measurements in unidirectional carbon fibre reinforced epoxy composites
(2021-03-03)
The present work introduces a novel methodology to analyse non-uniform residual stresses in composite materials. For robust determination of stresses in complex structures made of different layers, it is first necessary to prove that residual stress analysis in a single layer structure can reliably be accomplished. In present work a unidirectional carbon fibre reinforced epoxy is investigated. For residual stress determination, the integral incremental hole drilling method is used. It is revealed that the standard ...

Continuity and changes in food consumption pattern among Tibetan refugee community in India
(2021-09-29)
Background: Food consumption pattern of refugee communities was carried by many scholars but little is known about the food continuity of refugees in host country and its implications on health.
Aim: The present study highlights the issue of food continuity among Tibetan refugees in Bylakuppe settlement, India.
Methods: 200 household data were collected in order to understand food consumption pattern by employing household structured questionnaire. Simultaneously, 23 individual data were collected consisting first ...

On the influence of build orientation on properties of friction stir welded AleSi10Mg parts produced by selective laser melting
(2021-04-06)
Welding and joining of components processed by additive manufacturing (AM) to other AM as well as conventionally produced components is of high importance for industry as this allows to combine advantages of either technique and to produce large-scale structures, respectively. One of the key influencing factors with respect to weldability and mechanical properties of AM components was found to be the inherent microstructural anisotropy of these components. In present work, the precipitation-hardenable Al–Si10Mg was ...

Effects of Aging under Stress on Mechanical Properties and Microstructure of EN AW 7075 Alloy
(2021-07-20)
In the present study, microstructural and mechanical properties of EN AW 7075 following stress-aging were assessed. For this purpose, properties of stress-aged samples were compared with values obtained for conventionally aged counterparts. It is revealed that the strength and hardness of EN AW 7075 can be increased by the presence of external stresses during aging. Precipitation kinetics were found to be accelerated. The effects of conventional and stress-aging on the microstructure were analyzed using synergetic ...
