Vindpark Vänern : Fundamentteknik och Logistik

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

Tillväxtmönster och åldersstrukturer hos opåverkade bestånd av strömlevande Arktisk harr i Sibirien :

It is hard to find streaming waters where humans haven?t affected the fish populations or the running water it self. In many streams the fish populations are over harvested and this results in a lack of older and larger fish. This is also the situation for many populations of Grayling (Thymallus spp.). To be able to develop management plans and to perform actions that improve the situation for the grayling, it is therefore crucial to know what natural, by humans unaffected populations look like.

?Tillvaron [...] vidgar sig? : Alberte ? en Ny kvinna i genusomskapandets tid

This essay examines the Alberte triology, by the Norwegian writer Cora Sandel, from a gender/feminist perspective. Taking Yvonne Hirdman's theory about the gender system as a starting point I will show how the living conditions and the different roles of men and women are represented in the novel and how they are changing during the centuries before and after the First World War.I am particularly interested in Alberte, the main character, what attitude she takes to her position in the gender system and in what way she differs from the traditional female model. Is she a New Woman, a different ?species?, who doesn't fit into the rigid gender system? Does the New Woman have a male counterpart, and is he to be found in the novel? Does the novel give a positive vision of a future where men and women can meet as equals?.

Om matematikundervisningens svåra konst. Ett sätt att undervisa abstrakt bevisföring

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

Torkning av flis med restvärme : Metoder för att sänka återledningstemperaturen

The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.

Representation = legala mutor? : Gränsen mellan representation enligt 16 kap. 2 § IL och mutor eller andra otillbörliga belöningar enligt 9 kap. 10 § IL

Companies use different forms of representation to promote business negotiations. The regulations for the right to deduction for the cost of representation are stated in Chapter 16 section 2 of the Swedish Income Tax Act (IL). According to the law there must be an im-mediate connection between the expenditure and the business practice and the claimed de-duction must be reasonable. The Swedish tax authority publishes general recommendations regarding representation which are used as guidelines for the tax payer to follow. The gen-eral provision about tax deduction can be found in Chapter 16 section 1 of the Swedish In-come Tax Act (IL), stating that expenses to acquire or retain income shall be deductible.

Elevers föreställningar om liv : undersökning av elevers lärande ur ett socialkonstruktivistiskt perspektiv

The purpose with this study was to analyse students' conception of living things, and to establish how a social constructivist learning situation affect their conceptions. The method consisted of questionnaires, followed by group discussions and a final survey. The main result was that students have everyday conceptions about scientific phenomena that are reinforced by the social interaction. Some students were positively influenced by the interaction with their peers, where non-scientific conceptions were replaced by conceptions of a scientific nature. Furthermore, the cultural artifacts are of very good means, but the study showed a strong need for a knowledgeable person, e.g.a teacher, to guide students in the right direction during the discussions.

Bilder av Trotskij

My aim in this case study has been to create a method for creature design to test this method in a production and evaluate the results. To achieve this I studied and analyzed the methods of three concept artists and illustrators named James Gurney, Neville Page and Iain McCaig. From the analysis of these artist´s methods, combined with my own personal experience, a new method was formed. To test this method a creature was designed based on directives given by a game design group in the process of creating a table top role playing game in a fictitious world. These directives where given for the creature´s role and its living conditions.

Threats and opportunities for the survival of the Yangtze finless porpoise

The Yangtze finless porpoise (Neophocaena phocaenoides asiaorientalis), is a small freshwater cetacean which has recently fallen dramatically in number. It is an endemic species for the Yangtze River and unless drastic action is taken, it risks the same fate as the now functionally extinct Yangtze river dolphin (Lipotes vexillifer). Threats to the porpoise are diverse but they have in common that they are caused by man. Development of the river has been made to supply a growing human population with food, hydropower, and to reduce the risk of flooding. These changes have resulted in a degraded habitat for the porpoise.

Samhörighet och struktur - en studie av invandrargruppens politiska mobilisering

This essay deals with the paradox of why the immigrants in Sweden, despite their considerable size of 12 % of the population and common interest and living opportunities, haven?t mobilized politically in any significant way. The aim with this essay is to reach a theoretical understanding of why this paradox exist. By the use of a critical case and a theoretical model, based on theories of collective action, the conclusion of this essay is that, despite the fact that the immigrants have a common interest and an organizational structure, the immigrants in Sweden has not mobilized politically in any significant way. The main reason for this is that they have a weak common identity and they don?t have the structural opportunities to act..
