A comprehensive multiscale approach consisting of a combination of state of the art, first principles quantum theory and the flexible statistical methodologies of complex systems is applied in order to achieve a detailed microscopic understanding of the magnetic properties of rolled-up transition-metal [TM] ultrathin films and stripes. A quantum electronic investigations of the effective interactions between the local magnetic moments is performed as a function of composition and rolling radius R including the limit ...

Increasing climate variability continues to threaten livelihoods in southern Africa where communities face the challenges of addressing context specific complexities associated with rain-fed agriculture. Zimbabwe is equally vulnerable but the country is going through a transformation in agriculture through the implementation of climate smart agriculture practices that endeavour to enhance adaptation, resilience and increase productivity. The study was undertaken in Mutare district, Zimbabwe with the aim of exploring ...

Organic carbon is a major indicator of soil health, which can contribute to a sustainable agroecosystem. In Africa, mismanagement of agricultural soils has depleted the organic carbon pool. The decline in soil organic carbon has important implications for food security and environmental sustainability. This study examined the impact of monoculture and perennial systems on soil carbon sequestration after fifteen years of cropping in a tropical rainforest of Nigeria. Agronomic management in the monocultures of maize ...

Aus zwei Gründen gewinnt die Weiterbildung an Bedeutung: Einerseits entsteht im Zuge der digitalen und ökologischen Transformation der Arbeitswelt ein großer Qualifizierungsbedarf, weil sie zu einem Wandel von Berufsfeldern und -tätigkeiten führt. Andererseits spielt Weiterbildung auch mit Blick auf benachteiligte Gruppen am Arbeitsmarkt eine zentrale Rolle für deren Verbleib bzw. erfolgreiche Integration in Erwerbsarbeit. Allerdings ist die Ausgestaltung der Weiterbildung durch institutionelle Komplexität geprägt. ...

One of the main difficulties facing agribusiness development in Cote d’Ivoire, is the issue of benefit sharing. Although communal land is expected to be equitably beneficial to all who have a stake on the land, unclear benefit sharing principles and modalities affect the implementation of benefit sharing to the disadvantage of the rural communities. Using a qualitative research approach, the study investigates if the benefit sharing approach practiced by oil palm plantations investors in South Comoé align with globally ...

This study was conducted to evaluate the effects of using total mixed ration silage based on citrus pulp on feed intake, growth performance, serum metabolites and ruminal fermentation of growing female lambs. For this purpose, sixty-eight female Zel lambs (5-6-months) with an initial body weight of 20.65 ± 3.71 kg were randomly divided into two equal groups (n=34). Two isonitrogenous and isoenergetics diets were formulated based on corn silage (TMRC) and citrus pulp silage (TMRPS), respectively. To prepare TMRPS, ...

Die vorliegende Arbeit besteht aus mehreren Teilen historischer, städtebaugeschichtlicher und architekturgeschichtlicher sowie religionsgeschichtlicher Inhalte. Dies erwies sich als notwendig, um die verschiedenen Zusammenhänge leichter einordnen zu können. So finden sich auch Kapitel, die sich z. B. mit dem Kirchenbau in der NS-Zeit, dem Luftkrieg oder den gesellschaftlichen Verhältnisse der 1950er und 1960er Jahre beschäftigen. Dies erleichtert das Verständnis dafür, die Situation der damaligen Zeit besser ...

Smallholder agriculture has been identified to be critical in the creation of employment, improving food security and improving the economy. However, smallholder agriculture in Africa is characterised by a low production level which has been linked to the limited use of technologies. Several factors influence the adoption of technologies among smallholder farmers in Africa. This systematic literature review focuses on the factors influencing technology adoption among smallholder farmers in Africa and identified 128 ...

This thesis is set within the context of the problem of motion planning in autonomous driving. Due to nonlinear system dynamics and non-convex constraints, this problem is challenging even under simplifying assumptions (e.g. non-cooperating traffic participants obey traffic rules, lossless inter-vehicle communication, absence of measuring errors). Typical solution approaches rely on a decomposition of the problem into subproblems which are easier to solve. This decomposition often results in a hierarchy of subproblems ...

Most of the research works about consumer behavior toward olive oil are based on quality attributes and indicators. Consumption values have not been explored, especially for olive oil consumption. Thus, the present work proposes an analysis of the Tunisian consumer’s behavior towards olive oil, based on consumption values, especially environmental sustainability value since olive oil is typically a green and sustainable product. Drawing on the findings of a survey of a Tunisian household’s sample, an exploratory ...
