Through the integrated framework of participation theory and political economy, this article analyzes participatory opportunities in the virtual world Habbo Hotel, and how participation is constrained and framed by the producer’s commercial strategies, which are based on advertising and sales of virtual goods. The study also looks into the ways in which the producer Sulake Corporation discursively
The interactions of the ECM (extracellular matrix) protein asporin with ECM components have previously not been investigated. Here, we show that asporin binds collagen type I. This binding is inhibited by recombinant asporin fragment LRR (leucine-rich repeat) 10-12 and by full-length decorin, but not by biglycan. We demonstrate that the polyaspartate domain binds calcium and regulates hydroxyapati
In order to understand ritual in the past, archaeology has long relied on theories developed in other disciplines. While these theories, which often rely on written or oral information, have added many important dimensions to our interpretation of the archaeological record, they have often proven difficult to successfully articulate with the archaeological sources. Moreover, archaeology has tended
We present a framework based on object orientation with novel principles for how to store, analyze and integrate electrophysiological data. These principles are: (I) Using a Decorator pattern for storing analysis data in an object model, (II) using a Core Classes data structure for integration through mediation in a service bus architecture, and (III) choosing the single unit as the finest structu
Purpose - The purpose of this thesis is to explore the relationship between sustainable consumption and gender identity, with a particular emphasis on femininity, and to establish the normative idea of the green consumer. Methodology - As part of this thesis, three focus groups were conducted with a total of 19 participants. During the first part of the focus groups, the research aim was disguise
The world continues to be shaped by crises in both new and familiar forms. International and non-international armed conflicts and disasters are barriers to individual wellbeing, development, stability, and in the case of the former, represent a basic challenge to peace. The aftermath of such crises, in which communities can be rebuilt and the fabric of society can be mended, can be a time for rec
Poly-3-D-hydroxybutyrate (PHB) is a biopolymer naturally produced by a range of bacterial species. PHB production both from glucose and xylose has also been enabled by engineering the robust baker’s yeast Saccharomyces cerevisiae, however yields remain low. In the present study, additional modifications were carried out in S. cerevisiae strains already expressing functional enzymatic pathways for
G protein-coupled receptor 30 (GPR30) is a ubiquitously expressed receptor reported to bind and become activated by estrogen (17β-estradiol). However, the role of GPR30 as an estrogen receptor for rapid estrogenic signaling is not completely accepted, and controversies exist regarding the identity of the cognate ligand, signaling, and subcellular localization of the receptor. Expression of GPR30 i
In this thesis the heating area of a belt furnace for annealing metal powder has been modeled. The model was extended with PI-controllers for controlling the energy added to the model. It was simulated with differently tuned controllers to test tuning principles for finding suitable control parameters for the process. The most promising tuning principles was then written as a manual with the aim f
Tolkning och kvantifiering av strålningseffekter pga. atmosfäriska partiklar är en signifikant del av IPCC’s modellering av hur tidigare klimat förändrats och hur förändringar i framtiden kommer se ut. I den här studien vill vi strukturera och analysera observationer av huvudsakligen svavelpartiklar positionerade i stratosfären från naturliga och möjligtvis mänskliga källor, med hänvisning till va
Recently, several regions in southern Sweden suffered extremely low groundwater levels following a long-term infrequency in rainfall. In response, irrigation was banned in many of the affected municipalities during 2016–2017, amongst which Mörbylånga municipality was one. Because nearly half of the nation’s drinking water is extracted from groundwater, protecting and managing this vital resource i
In this work a strategy for numerical simulation of punching during concurrent pressing of stainless steel sheet metal has been investigated accounting for the stress triaxiality and Lode angle parameter. Modelling of the damage evolution of a sheet metal is a useful tool within the field of engineering and materials science, and can provide useful information regarding material capabilities in a

The primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. The PSTs have historically been designed based on hydraulic
In the Spring of 2003, Severe Acute Respiratory Syndrome ripped through China and the world. What it left behind in China was a country greatly improved in terms of social health levels, political transparency, financial stability and quality of life. From an ability to handle future crises and increase in international investor quality, China emerged intact, and improved. This paper outlines the
Since the Second World War, the systems of trade and environmental law have evolved very differently. It is claimed that the complete trading system impedes the development of the more shattered environmental system and that conflicts between them are likely to increase. Some argues that a solution would be to incorporate the environmental system should in the WTO. The purpose of this thesis is t
Since 1999, the World Bank (WB) and the International Monetary Fund (IMF) encourage developing countries to prepare the so called poverty reduction strategies (PRSs), which are national integrated strategies formulated through a participatory process coordinated with donors. This research has aimed to contribute to the development of effective PRS, especially the Sustainable Development and Povert
Free movement of goods is regulated by Article 28 of The EC Treaty. The most important judgments of European Court of Justice (ECJ) in this field are Dassonville, Cassis de Dijon and Keck. The interpretation of Article 28 was very broad in Dassonville and Cassis cases therefore the national rules which were designed for social policy reasons, but not for controlling the trade between Member States
The principle of ne bis in idem is one of the fundamental principles recognizing human dignity in criminal procedures. The principle's objective is to convey legal certainty to the individual. It aims to ensure this by prohibiting 'double jeopardy', i.e., an individual cannot be subjected to criminal proceedings more than once for one and the same - allegedly criminal - conduct after o
