The adsorption of glucose and polysaccharides onto solid surfaces is important in several areas of science and engineering including soil chemistry and mineral processing. In this work we have studied the adsorption of D-glucose at the water-goethite (alpha-FeOOH) interface as a function of pH using batch adsorption measurements and a simultaneous infrared and potentiometric technique. Molecular o
Sexual selection has traditionally been used to explain exaggerated sexual traits in male animals. Today the concept has been developed and various other sexually related traits have been suggested to evolve in the same manner. In nearly all new areas where the theory of sexual selection has been applied, there has been an intense debate as to whether the application is justified. Is it the case t
Combining multiple III-V materials into axial nanowire heterostructures has enabled the fabrication of custom nanowire-based devices useful for a wide range of applications. However, our ability to form axial heterostructures between arbitrary combinations of III-V compounds is impeded by a lack of information on the dynamics of the heterojunction formation process, often resulting in suboptimal h
In Africa, women's status in politics, their economic standard and their position within social hierarchies and practices is subordinated to that of men. The aim of this thesis is to examine how colonialism, liberation ideology and women's movements have influenced the empowerment of women in South Africa, Zimbabwe and Mozambique and attempt to account for why women in South Africa have at
This thesis examines the reasons behind the Swedish migration policy reform which led to a replacement of the Aliens Appeal Board by the Migration Court. This introduced a two-party procedure, oral hearings and enhanced transparency. It was designed to guarantee the rule of law and to thwart political arbitrariness. The transfer of power from representative institutions to judiciaries is referred
This thesis explores the resurgence of Native American identity. Scholars have observed a dramatic increase of people identifying themselves as Native Americans over the past forty years in the decennial US Census. The increase coincides with the introduction of racial self-declaration in 1960; according to scholars this enables a process of ethnic switching where individuals change their race fro
This thesis attempts to understand the ways in which popular film is integrated into the everyday lives of urban middle class youth in India. Approaching the study of film through an audience reception approach, I engaged in participant observation and interviews during a fieldwork period in New Delhi in order to better understand how a young audience might negotiate the fantasy of filmic images i
Europe is struggling to reduce its CO2 emissions and to fulfil commitments made according to Kyoto protocol. At the same time, Europe does not possess enough fossil energy resources to cover its needs and thus consumption of imported fossil fuels is growing, placing threats upon economic stability. In order to combat these challenges, renewable energy sources and biomass in particular are expected
This essay examines contemporary political discourses about the Mau Mau insurgence, which took place in Kenya in 1952-1960. During the Mau Mau, the people living in the Central Highlands region, mainly of the Kikuyu ethnic group rebelled against colonial rule. The British came down hard on the Mau Mau, detaining, killing and torturing large portions of the Kikuyu population. There was a divide wit
Motivation is a hot topic in the corporate world and managers are searching for ways to motivate the workers in order to improve performance. Profit-seeking organizations are able to control the workers motivation and actions, because they are usually in higher power and employees are often dependent on the organization for monetary reasons (Sayer, 2007). But what about managers in voluntary organ
Resulting from CSO critique of the Paris Declaration signatories of the Accra Agenda committed themselves to deepen CSO engagement in national aid effectiveness. Therefore the purpose herein is to increase understanding over functions, mechanisms, hindrances and opportunities facing CSO in this process in Tanzania. The primary method for achieving this was semi-structured interviews with 21 perso
Background: In obese patients, jejunoileal bypass (JIB) has been used to induce weight reduction. Changes in the neuroendocrine system may be affected by the JIB-operation, because the proximal small intestinal mucosa has a rich supply of endocrine cells and peptidergic nerves. Materials and Methods: In 37 obese patients operated with JIB 1-30 years ago, small intestinal biopsies were taken at the
In order to assess the potential of hydropsychid capture net anomalies as a bioindicator of chronic toxicity in streams and rivers, the effects of 2,4-dichlorophenol (2,4-DCP) exposure on the net-spinning behavior of Hydropsyche slossonae were examined for anomalies after 0, 5, 10, 15, and 20 exposure days to gradient concentration of 2,4-dichlorophenol. The net-spinning behavior was significantly
This paper reports on a test of the validity of Pienemann's (1998) Processability Theory (PT). This theory predicts that certain morphological and syntactic phenomena are acquired in a fixed sequence. Three phenomena were chosen for this study: attributive adjective morphology, predicative adjective morphology, and subordinate clause syntax (placement of negation). These phenomena are located at s
The aim of this chapter is to discuss global environmental change (GEC) through the social construction of nature and notions of authenticity. We will discuss the social construction of nature in a specific context, namely that of different kinds of nature-based tourism. The argument will revolve around what we perceive as a shift in focus from the image of nature as thing to nature as experience,
The purpose of this article is to present and analyse gender sensitive interpretations of Islam in Indonesia and a reform of fiqh from a gender perspective. These interpretations can be seen as an expression of Islamic feminism, a discursive framework that has grown from the Islamisation processes of Muslim societies in the 1980s. Another aim is to depict the specific Indonesian environment where
In this study, a fully three-dimensional calculation method has been further developed to simulate and analyze various processes in a thick anode duct. The composite duct consists of a porous layer, the flow duct and solid current connector. The analysis takes the electrochemical reactions into account. Momentum and heat transport together with gas species equations have been solved by coupled sou
