Sustainability of traditional cocoa agroforests in Ghana
(2022)
Cocoa (Theobroma cacao L.) is an important agricultural commodity that is important to the economies of many countries in the world. Due to cocoa’s dependence on fertile forests soils, its production is a major cause of deforestation and soil degradation in producing countries. When grown in agroforestry systems it can conserve biodiversity, sequester carbon (C), and maintain soil fertility. There are many cocoa agroforests which are managed without synthetic agrochemicals. Because organic cocoa certification is now ...

Identification of socio-economic characteristics and farmers’ practices affecting rice (Oryza spp.) yields in Benin (West Africa)
(2022-12-28)
Rice (Oryza spp.) is one of the major staple foods in Benin. Benin has increased rice production through the expansion of cultivation area rather than increasing rice yields. To better understand the factors affecting rice yields, a thorough understanding of the current rice production system characteristics and constraints is required. The present study identifies socio-economic characteristics and farmers’ practices affecting rice yields and suggests improved cultivation practices in the sector. Data were collected ...

Planungshilfen zur Geschwisterkalbhaltung – Management und Kostenkalkulationen
(2022)
Im Rahmen der vorliegenden Bachelorarbeit wurden Planungshilfen entwickelt, die die praktische Umsetzung der Geschwisterkalbhaltung auf Milchvieh- oder Kooperationsbetrieben erleichtern sollen. Dabei sollen zum einen die Betriebsleiter*innen bei der Erarbeitung von betriebsspezifischen Szenarien für die potenzielle Geschwisterkalbhaltung unterstützt und zum anderen eine Berechnung der mit der Umsetzung verbundenen Kosten ermöglicht werden. Als Basis für die Entwicklung der Planungshilfen diente eine Literaturstudie. ...

Statik und Einflussfunktionen - vom modernen Standpunkt aus
(2022-01-06)
Darstellung der rechnerorientierten Statik mit besonderer Betonung der Rolle der Einflussfunktionen für die moderne Statik:
Den Anstoß zu dem Buch gab die Erkenntnis, dass die Methode der finiten Elemente ein Rechnen mit genäherten Einflussfunktionen ist. Ein klassisches Thema der Baustatik ist mit den finiten Elementen wieder auferstanden. Das war zunächst überraschend, aber es war dann Anlass die Grundlagen der Statik aus der Sicht der computational mechanics neu zu überdenken. Mit computational mechanics meinen ...

Maßnahmen zum sozialverträglichen Wiederaufbau der zerstörten Wohngebäude in den informellen Siedlungen in Aleppo unter Würdigung historisch gewachsener Strukturen basierend auf soziokulturellen, planerischen, ökonomischen und baurechtlichen Aspekten.
(2022)
Durch den Bürgerkrieg wurden Teile im Osten Aleppos und insbesondere die sogenannten informellen Siedlungen, die einen Beitrag zur Wohnraumversorgung für etwa 1,00 bis 1,25 Mio. Menschen in Aleppo geleistet haben, am stärksten zerstört. Diese Zerstörungen stellen den Ausgangspunkt der vorliegenden Arbeit dar. Im Vergleich zum modernen Westen Aleppos, in dem freigestellte, zu Blöcken geordnete Mehrfamilienhäuser das Straßenbild bestimmen, sind die informellen Siedlungen als selbstorganisierte Siedlungen im Ostteil ...

The multifarious politics underlying food production, distributions as well as consumption are often ignored. The present paper analyses different factors affecting food consumption in the local population of Saudi Arabia and relates them to the supply chain. Different futuristic scenarios are discussed to develop sustainable food consumption practices ...

The First Informationexplosion
(2022-06-20)
The paper places punch card technology in the context of the office machine industry in Germany and discusses the exciting relationship between the two competitors on the market for punch card technology, Dehomag and Powers, in Germany. The question is whether the leading role of the United States in the use of office machines frequently cited by Anglo-American authors really applies. How punch card technology in Germany has advanced from its beginnings is discussed under the heading of rationalisation strategies. ...

Nominal Science without Data
(2022-09-28)
Expanding upon literature on early digital computers, this paper shows the role mathematicians have undertaken in founding the academic fields of Game Theory and Operations Research, and details how they were supported by the mathematics departments of military agencies in branches of the US Armed Services. This paper claims that application is only decoration. Other than astronomy, physics and engineering, where experiments generate data analysed with the aid of models and appropriate software on computers, Game ...
