Abstract When a dung beetle has arrived at a dung pat, it soon starts to form a ball, which it will later roll away in a straight line. Rolling in a straight line ensures that the beetle will never risk rolling back to the fierce competition at the pat, thus eliminating the chance of getting its ball stolen by others. Before rolling out from the pat, the beetle performs an orientation dance on to
Aluminium alloys are used in a wide range of applications due to their high tensile strength concomitant with low density. Additionally, aluminium alloys form a naturally occurring and passivating oxide layer, which leads to high corrosion and weathering resistance. In industrial manufacturing, aluminium alloys acquire their desired properties through specially designed heating processes. A common

This is a very general manner that previously placed young people live or has lived more volatile and turbulent, with changing within education and very poor self-management, What these peoples experience when they enter the independent adulthood is an a
Previous research has mainly addressed the impact of over/under-education on wages in developed countries. Therefore, this paper attempts to fill the void gap in the literature by empirically examining the impact of over-education and under-education on wages in a developing country, namely Egypt, using the 2012 Egyptian Labor Market Panel Survey (ELMPS). In order to do so, actual years of educati
The ambition of this thesis was to provide Scania with a program that can calculate power losses in hypoid gears from gear teeth mesh using the programming language Python. The program should be able to calculate power losses on different points on the gear flank to help designers and engineers in the development face of a new axle gear. Because of governmental requirement and costumers’ wish to m
Thesis purpose: The purpose of this study is to examine what factors moderates or influence the entrepreneurial orientation. Our study provides a unique context that was examined. Argued by theory, moderators vary according to different contexts. Subsequently, we want to confirm some of the moderators discussed in literature and research what other context specific moderators that exist. Furthermo

This was investigated by conducting four case studies of India, Thailand, South Africa and Brazil. It was found that prices had been affected by TRIPS due to the extension of patent term in
We live in a digitalized society. All the abundant data we produce, today called “Big Data” it changing our lives, and will soon disrupt it. Different studies and analysis argue about the advantages that Big Data comes in, not only as a competitive advantages for the data holders, but also in health, government, for the citizens and society as a whole. Nevertheless, Big Data comes with significant
This study is a knitted attempt of academic border crossing. The methods used for this analysis are discourse theory and autoethnography. In using autoethnography the aim is to include other experiences than those who are usually theorized. The material used for the study is five knitting books published in 2013. Concepts are discussed as processes trying to stabilize meaning in the discourse. The
Stormwater from urban areas contain a number of pollutants, among which nitrogen and phosphorous have been of lesser focus. In this study I aim to investigate if biochar has the potential to fill the role as water filter in urban areas, and to pin point what should be experimentally investigated in order to evaluate biochar in comparison to two contemporary filter systems: bioreactors and chalk fi
Business Intelligence (BI) users have started to demand more flexible products, which has forced the BI field to move towards self-service. Flexible products do however imply new challenges for designers, in order to facilitate such design. Thus, BI designers must be capable of understanding organizations better and what decision makers need, and thereafter frame appropriate solutions for them. Th
