Competitive interaction between guava and weeds: Effect on initial growth
(2019-12-03)
Guava (Psidium guajava L.) is one of the 50 most consumed fruits in the world. However, weed competition compromises fruit production in cultivation areas. Thus, this work aimed to evaluate the competitive interaction between guava plants and common infesting species on initial growth. Guava seedlings were cultivated during 60 days with Bidens subalternans DC., Waltheria indica L. or Commelina benghalensis L. in a randomized block design with four replicates. The experiment was conducted under greenhouse condition ...

Erlebnisführer Dönche
(Universität Kassel, Fachbereich Architektur Stadtplanung Landschaftsplanung, Fachgebiet Landschafts- und Vegetationsökologie, 2019)
Mit dem wachsenden Umweltbewusstsein zeichnet sich ein neuer Trend ab: Die Natur ist nicht mehr allein um ihrer selbst willen schützens- und erhaltenswert, sondern auch als Ort der Ruhe und der Naturerfahrung. Vor allem stadtnahe Naturerfahrungsräume rücken zusehends in den Blickpunkt der Öffentlichkeit, da sie für jedermann schnell und unproblematisch erreichbar sind. Spannende Ausflüge mit der Familie oder mit Kinder- und Jugendgruppen sind einfach zu verwirklichen. Die Dönche mit ihrer Lage unmittelbar vor den ...

Flexible Foams made of Liquid Silicone Rubber and expandable Microspheres
(2019-10-02)
In this study, the possibility of foaming liquid silicone rubber (LSR) was investigated. The foam was produced by injection molding with two different thermoplastic, expandable microspheres. Different properties were tested using the S2-tensile bar, e.g. density, tensile strength, specific tensile strength, elongation at break, stress at 100 % strain and the hardness. It was found that the two types of microspheres used have similar effects on density, specific tensile strength and elongation at break, but differ in ...

Statik und Einflussfunktionen - vom modernen Standpunkt aus
(2019-01-15)
In dem Buch werden die Grundlagen der klassischen Statik in einer modernen, zeitgemäßen Form dargestellt. Dabei wird auf Präzision und Prägnanz in der Darstellung Wert gelegt. Spezielles Gewicht wird auf Einflussfunktionen gelegt, da diese die Basis der finiten Elemente bilden. Das Rechnen mit finiten Elementen ist, wie in dem Buch gezeigt wird, ein Rechnen mit genäherten Einflussfunktionen. Der Text geht ausführlich auf die Fragen der Modellierung von Tragwerken mit finiten Elementen und der Genauigkeit der numerischen ...

Biofuels and livelihoods: Empirical findings on the welfare impacts of Jatropha cultivation in the Mangochi district, Southern Malawi
(2019-11-27)
This study evaluates the welfare impacts of jatropha (Jatropha carcus) cultivation measured as consumption expenditure per adult-equivalent for smallholders in southern Malawi. Household survey data from the southern region of Malawi collected in 2014 from 303 smallholders using purposive and random selection strategies were used. Propensity score matching and endogenous switching regression methods were employed to address the selection bias problem and to control for observed and unobserved covariate effects. The ...

The Fatigue and Corrosion Fatigue Behavior of Austenitic Stainless Steel AISI 304 after Deep Rolling at Various Temperatures
(2019-09)
The austenitic stainless steel AISI 304 was deep rolled at 20 °C (RTDR), -195 °C (CTDR), and 550 °C (HTDR). The deep rolling pressures used for each deep rolling temperature were 1.0, 1.7, and 2.4 bar. From microstructural investigation, the largest compressive residual stress field was found in RTDR, and the highest amount of martensitic content and plastic deformation were found in CTDR. The strain aging effect was only found in HTDR.
In the rotating bending fatigue tests, the strain aging effect after HTDR is ...

The impact of uncertainty on smallholder farmers' income in Kyrgyzstan
(2019-12-12)
The farming systems in the mountain areas of Kyrgyzstan are primarily characterised by small-scale crop and livestock activities. Farmers are faced with several environmental, socio-economic and political challenges and constraints that result in significant uncertainties affecting their operations. This paper attempts to model how various sources of uncertainty collectively affected the smallholders’ farm incomes during a mid-term horizon using Monte Carlo simulation. The analyses were based on data collected through ...

The choice of institutions to solve cooperation problems: a survey of experimental research
(2019-11-01)
A growing experimental literature studies the endogenous choice of institutions to solve cooperation problems arising in prisoners’ dilemmas, public goods games, and common pool resource games. Participants in these experiments have the opportunity to influence the rules of the game before they play the game. In this paper, we review the experimental literature of the last 20 years on the choice of institutions and describe what has been learned about the quality and the determinants of institutional choice. Cooperative ...
