In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature was used. Measured responses were pellet bulk density, pellet durability, amount of fines, pelletizer motor current, pellet temperature, die temperature and CV for pelletizer motor current (a measure of process stability). Each response was modeled by multiple linear regression (MLR).

This paper addresses the need to review the modern presentation of textile archaeology in museums. It is time to look at textiles in archaeology with new eyes. The reality behind archaeological textilestudy is holistic, embracing many different aspects of society. The presentation of textiles has in my opinion become old-fashioned. I will show in my paper that Jonathan Adams? `seven constraints´ model, developed for research on ancient ships, can also be applied to textile research.

A quantitative study was conducted with the aim to investigate whether individuals use a specific conflict strategy when they are in a task conflict or a relationship conflict in their workplace. The study also examined whether individuals experience positive or negative effects of a task conflict or a relationship conflict when a specific conflict strategy have been used. Previous research explains the effects of task conflicts and relationship conflicts at the workplace (De Dreu, 2008) Likewise lifts the effects of the conflict strategies interaction, avoidance, and power and coercion (Hoerr, 2005; Meyer, 2004; Trudel & Reio Jr., 2011). However it does not tie together what the conflicts and conflict strategies have for effects together. This also means that it is impossible to discern if there is a strategy that is frequently used in a specific conflict type. The study group consisted of 62 participants from different workplaces that responded to a survey.

Hur handskas vi med den arbetsrelaterade stressen och finns det faktorer som kan minska den? I denna studie undersöks upplevelsen av stress och socialt stöd i forskarmiljö. Undersökningens deltagare består av 45 forskare i Lund och Malmö som besvarat en enkät. Enkäten lämnades ut våren 2003 och 2005. Syftet var att undersöka om fritidsintresse och socialt stöd kan minska stressen som kan uppkomma i samband med arbetet.

Sweden is usually seen as a role model when it comes to integration and diversity, but at the top of the pyramid there is little ethnical diversity to be found. This paper investigates how existing economical and sociological theory explain the lack of swedes with foreign background in leading positions in large Swedish companies. Our findings show that none of the theories applied in this paper can explain the phenomenon in isolation. Thus it is not only taken for granted norms, contacts in one's network or cost minimizing under asymmetric information that lie behind the phenomenon, but an interaction of these aspects. Conflicting demands lead the recruiters to separate talk from decision, the search frame is narrow and no or small efforts are made to increase the diversity.

The objective of this study was trying to understand bullying focusing on the bully. The questions at issue were: What can contribute in the making of a bully? What are the benefits and losses in bullying? What are the former bullies? thoughts on bullying, now in comparison to in their youth. This was investigated with a qualitative approach from a former bullys perspective, hence three former bullies were interviewed. The result was presented in themes and was then analysed from a social psychological and social constructionist perspective.

In this thesis we calculate the Hawking mass numerically for surfaces in Kerr spacetime. The Hawking mass is a useful tool for proving the Penrose inequality and the result does not contradict the inequality. It also does not contradict the assumption that the Hawking mass should be monotonic for surfaces in Kerr spacetime. The Hawking mass is quasi-local and defined by the spin coefficents of Newman and Penrose, so first we give a discussion about quasi-local quantities and then a short description of the Newman-Penrose formalism..

Listed corporations achieve effectiveness through segmentation of investors. Categorization of like- minded investors diminishes goal incongruence. This thesis aim to examine an Investor models accuracy, provided by a Professor Emeritus in Economic Psychology in 2001. This model segments investors as active, passive, speculative and naive investors. This thesis has a demarcation to private investors on the Swedish stock market. It has a deductive and qualitative approach as the purpose is to study the Investor model.

When it comes to investigating the motives behind activism, the members of political study have a lot to say. I aimed to critiqually rewiev this in my thesis. I asked the question ?What do the actor themselves claim lay behin their decision to become motivated?? To highlight this complex dilemma, I sought to discuss new social movement theory by comparing it to reality. This includes a literate examination on contemporary political science approaches, and a study of two organisations in the south of Sweden, choosen not to despise any excisting theory, but to give it a sense of reality.

Our essay is about the grammar structure that the participants in A- and B- level of a school in the middle of Sweden, in the subject, Swedish as a second language, process. We have collected written productions from an A-level group and a B-level group and made a comparison between them morphologically and syntactically according to the processability theory by Pienemann.Processability theory was applied to Swedish by Pienemann & Håkansson (1999), with five steps in syntax and four steps in morphology. It turned out that the B-level group had much higher processing level of grammar than the A level group and one of the reasons for this can be that grammar is explicitly taught during the first year of studying Swedish as a second language in the school we have chosen to study..

The environment has become an important part in people´s lives, and in today´s society stakeholders demands have increased upon companies when it comes to sustainability reports. How these sustainability reports are designed depends on whom it?s for, laws and regulations, and the companies own norms and values. The purpose of sustainability reports is to measure, monitor and compare a company´s enviromental impact. It?s not only about integrating economics, but also enviromental and social standards together to get both financial and competitive advantages.Sustainable Value method is a new model and is the first real method that can be used to evaluate a company´s resources, both financial, social and enviromental to a sustainable value.This model is used to compare the resource efficiency between companies.In this thesis, a documentary study with an experimental approach has been made.Sustainability reports from six selected companies (in the engineering and forestry sector) have been investigated with respect to their accounting for carbon dioxide, and an experiment using the method ?Sustainable Value Approach? was subsequently performed.

Violent crime can traditionally be classified as a reactive or an instrumental aggression. A reactive aggression is often characterized by some sort of provocation by the victim and the act is impulsive and the offender reacts by harming the victim. The provocation can be a threat, an insult or an attack and the act can be said to be a reaction induced by emotions. An instrumental act of violence however, often described as planned, targeted and emotional cold. The goal of the act can be to acquire money or power to maintain their status.
