The Weight of Nature
There is an expression called ?grief of climate? that refers to feelings of powerlessness and heaviness related to the environmental problems of today. A feeling that every move we make has bad consequences for nature. This essay is an investigation of how art in general and jewellery art in particular can be a way of discussing and visualizing current environmental problems and the complex relationship between human and nature. I am discussing how artworks dealing with a dark and dystopian picture of the relation can be seen as the memento mori of our time.
Analys av linjetaxering i samband med gallringsinventering med avseende på kvalitet, tillförlitlighet och framtida utformning
Modern forest owners are very familiar with forest management and forest economics. Therefore they have high demands for quality in forest operations. Guarantee of quality in the shape of self-checking activities is an important tool to guarantee a well managed forestry operation. To meet the forest owners? demands on guarantee of quality and the entrepreneurs wish of an easy method for self-checking, the forest owners association, Södra skogsägarna, has developed a new method for thinning inventory.
The purpose of this study is to evaluate the method that is used for self-checking and to find ways to develop and improve of the method.
The data has been collected by inventory in a number of stands with circle-area survey and with strip survey, which is method that is used for self-checking.
The results show that the strip survey does not diverge more than ±10 % in measuring values of basal area, number of stems, roads share, thinning quotient, outtake of basal area and total volume compared to circle-area survey.
Solceller som energikälla och solskydd för tält
This degree project is an investigation of solar cells and their ability to deliver electric power as well as reducing the need for cooling. The main object of interest is a BASE-X shelter. The shelter is purchased by the Swedish Defence Materiel Administration, FMV to be used for command and camp in the new force called Nordic Battlegroup, NBG. The demand on the equipment is firstly that it should have a small weight to be easy to transport and handle and secondly to be easy to bring up fast. Therefore the choice of solar cell technology fell on thin film cells.
Miljö- och samhällsekonomisk analys av behandling av biologiskt avfall
Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.

Inställning av automatikermed spänningsreglerande verkani det sydsvenska 400-130 kV nätet
The voltage level in the power grid varies due to variations in load and production. Normally these variations are manageable, but they may be excessively large during a disturbance. If the voltage is too high it may damage the equipment in the grid and too low voltages may cause problems like voltage instability. The magnitude of the voltage variation depends on the short circuit power capacity of the point of interest.This problem may become lore prominent due to automatic voltage regulation that acts on shunt reactors and shunt capacitors. When the shunt reactor is connected or disconnected to the grid it may cause such large changes in the voltage that the shunt reactor starts hunting.
Svenskt och norskt barnavårdsarbete : en jämförande studie av socialtjänstens konkreta barnavårdsarbete
This essay aims to examine and compare Swedish and Norwegian social work with children. It is a comparative study between two social welfare offices, in districts with similar population and problems, one located in Stockholm and one in Oslo. The main questions were; how is the work organized and carried out, what type of help and assistance is available and what kind of discretion and powers do the social workers have. In our essay we used qualitative methods mostly based on interviews, vignette questionnaires and documents, but also written research. In our analysis we used modern organisation theory and street level bureaucracy to seek explanations.The two welfare offices have similarities and differences.
To derive quality from quantity
The purpose of this master thesis is to present a model that illuminates the important factors when deriving technical information from market data within a company. For companies to be able to become and stay competitive in the market, product quality is an important factor. Whilst good product quality leads to customer satisfaction and loyalty, lack of quality brings costs in service and replacements. To improve product quality, the developers need information and knowledge about what quality issues affect existing products. Most companies gather data from market about known issues, but in order eliminate known quality issues in new products; this data has to be transformed into information and knowledge.
Problemhundar : En studie inriktad på hundar med grava aggressions- och rädsleproblem
Dogs with behavioral problemsThis study was made to investigate if there was a problem in today?s society regarding dogs showing for example excessive aggression and/or anxiety. The main questions in this study was "is there a problem today" and "if there is a problem, what can we do to prevent it". To investigate these questions interviews were made with six different professions concerning the dog domain. The result of the study shows that three of the interviewed considered it to be a problem, one did not have an opinion on the matter and two choose not to call it a dog related problem because it mostly depends on the owner.
En studie av sex ISA-system
On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.
Rollen som intern kvalitetsrevisor för ISO 9001. : Hur synen och förväntningarna på internrevisionsrollen påverkar kvaliteten på interna revisioner.
AbstractThe control of quality standard ISO 9001 has made the internal audit to be experienced as police authority and paragraph control. Because of that, motivation for internal auditors is low. To counteract the experience, there is a possibility to integrate internal audit with improvements in company?s processes. Theory has shown that a qualified and competent auditor can provide information that can help the organization's managements to make the right decisions that will improve product quality and result in new customer contracts.An opportunity to observe an internal and external audit at one of the case companies gave rise to this study.
Behövs kattetologer på djursjukhus i Sverige? :
Behaviour problems are often behaviours that cat owners don´t like, but are normal to the cat. The reason to why cat owners experience certain feline behaviours as problematic is probably due to the current practice in cat housing. The ways that cats are kept today causes somewhat of a compromise between cat and owner and inhibits the expressions of the cat's natural and normal behaviour. The cat owners may misunderstand their cats behaviour, for example the cat owners believe that their cats perform certain behaviours because of feelings of guilt, hate, revenge or maybe to protest against something or someone. An animal hospital may help solve behaviour problems, but also help the cat owners to undstand their cat´s behaviour in an other perspective.
The aim of this study is to investigate the need of a cat ethologist in animal hospitals.
Lärares förhållningssätt till demokratisk undervisning och sin egen maktposition i undervisningsarbetet
The aim of this paper is to examine how teachers experience their possibilities to develop democratic teaching in high school and how they reflect upon their position of power within the teaching situation. Four professional high school teachers have been interviewed for the study. The theoretical perspective of the study is an intersectional view on power and a view on democratic teaching which is partly built on the high school curriculum, but mainly defined by deliberative conversations, anti-oppressive education and norm-critical education. The result of the study is focused on three themes, which were shown in the analysis of the interviews. These themes are: choices of teaching content, authority of the teacher and democratic teaching.
