Are farmer perceptions among significant determinants of adoption of agricultural diversity in Malawi? A case of Lilongwe district
(2020-12-14)
Agricultural diversity can strengthen resilience of livelihood of farmers to climate change and market uncertainties while, potentially at the same time, o ering better dietary and nutritional prospects for households. Adoption of agricultural diversity in Malawi is low. Policy-makers, researchers, non-governmental organisations (NGOs), and extension staff need to understand dynamics of adoption of agricultural diversity in order to develop appropriate policies and interventions to promote agricultural diversification. ...

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 ...

Effect of Grain Statistics on Micromechanical Modeling: The Example of Additively Manufactured Materials Examined by Electron Backscatter Diffraction
(2020-02-21)
Micromechanical modeling is one of the prominent numerical tools for the prediction of mechanical properties and the understanding of deformation mechanisms of metals. As input parameters, it uses data obtained from microstructure characterization techniques, among which the electron backscatter diffraction (EBSD) technique allows us to understand the nature of microstructural features, that are usually described by statistics. Because of these advantages, the EBSD dataset is widely used for synthetic microstructure ...

Effect of Tool Temperature on Mechanical Properties and Microstructure of Thermo-Mechanically Processed AA6082 and AA7075 Aluminum Alloys
(2020-06-08)
The present work focuses on the effect of thermo-mechanical processing on the mechanical properties and microstructural evolution of AA6082 and AA7075 aluminum alloys using a novel forming process, i. e. integrating solution heat treatment, hot forming and tool quenching. Different tool temperatures ranging from 24 °C to 350 °C were applied to investigate their influence on mechanical strength and ductility. By using various tool temperatures, this study aims to provide insights needed for tailoring the mechanical ...

50 AÑOS HACIENDO, ENSEÑANDO Y COMENTANDO ARQUITECTURA EN EL PERÚ
(2020-10-17)
"No es tarea fácil resumir en el tiempo disponible la amplia y larga vida profesional que he ejercido con Antonio Graña y Eugenio Nicolini. Complica más la tarea, el hecho de que ella haya estado imbricada con una dedicación académica y una actividad periodística también muy exigentes. A ello, tendría que añadir mi incursión en política y la actividad museográfica, todo lo cual he ejercido con una simultaneidad persistente.
Procuraré por tanto mostrar una fracción de los más de 450 proyectos desarrollados por nuestro ...

ARQUITECTURA Y SOCIEDAD
(2020-11-07)
La presentación pone en relevancia el desarrollo de la práctica arquitectónica desde una perspectiva social, una en la cual el ciudadano asume un rol protagónico en la construcción del hecho arquitectónico y en la que el arquitecto orienta y conduce un proceso de carácter multidisciplinar.
Así, la propuesta arquitectónica no solo está resuelta por la triada vitruviana o por el “maravilloso juego de los volúmenes bajo la luz”, sino también por la historia, la cultura, la memoria y su gente. Esto supone diseñar desde ...
