This thesis studies settlement continuity on Gotland between approximately AD 200 and AD 1700. The method used is to calculate correlation between the geographical distribution of all known Iron Age stone-wall-houses (on Gotland known as "kämpagravar") and all farms included in the detailed taxation maps from approximately 1700. The number of remaining house foundations is between 1800 and 1900. A model to estimate the number of removed foundations is presented. It is based on the assumption that the settlement density was proportional to land use around 1700, and that the rate of removal is related to the current land use.

This paper examines possible applications of fuzzy logic on the field of artificial intelligence in digital games. It describes fuzzy logic in contrast to crisp logic. The paper will give several examples of possible applications of fuzzy logic-based decision making for game AI. These examples include the choosing of weapons for AI agents and the gas-break decision of an AI-controlled car. The paper will also analyze the impacts of game AI which makes decisions based on many factors.

The aim with this study was to investigate the effects a change of manufacturing process would have on the mechanical properties of drill bits made of a WC/Co composite used for stone cutting. The method used today is sintering, where the material is heated in a conventional sintering oven. The other method was microwave sintering, where the material is heated by radiation in the microwave region. Also an investigation of the manufacturing cost were made.The main difference between the two heating methods is that the conventional way is a rather slow process and the microwave method is very fast. The material is also heated homogeniously in the method with mirowaves, aposed to the case with the conventional sintering where the material is heated from the outside in.This makes the material harder and more wear resistent.

Haldex Barnes Hydraulics (HBH) is a company which produces hydraulic aggregates for use in forklifts, construction equipment, and trucks. The last two years the company has expanded. This has lead to an insufficient production of aggregates. Thus wishes HBH to increase their production without making to large investments.This report includes a now-state analysis of the problems and where they are. From this a further analysis of possible improvements are made.HBH works mainly with assembling and this is made manually.

The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.

The purpose of this study is to better understand patients suffering from psychotic illness along with their family members, and to identify treatment factors that have been helpful for these patients and their families by investigating how their relationships have been affected by treatment. In this way, treatment methods can be put in a theoretical context, treatment efforts can be clearer, and the therapist can develop professionally.The research method used is a semistruktureted interview conducted with tree patients and their families. One conclusion one can draw in the successful treatment with psychotic patients is strongly based on the therapist?s ability to build a safe and secure treatment alliance with both the patient and his family members. Meeting with patients in situations outside of the therapy room have been of great importance for the therapeutic process.Important themes for recovery that come forth during the interviews with the patients are the quality of the therapy session as healing factor.

In 2003 the recommended phosphorus allowance for dairy cows in Sweden was lowered approximately 10 %. For a cow at a production level of 35 kg ECM it decreased from 0,40 to 0,36 % of dry matter. To investigate if the decrease has been implemented at farm level, analysis of following minerals; P, Ca, Mg, K, Na, S, Se, Cu, Mn and Zn was performed on the TMR at 20 farms in Sweden in the summer of 2004. The purpose was to describe the actual allowance of different minerals as compared to the new recommendations. One hypothesis was that the decrease in recommended allowance of phosphorus would lead to the need of new mineral feeds on the market.

The purpose of this thesis is to analyse and propose improvements to the cost accounting system in use at an airline operating on the Swedish market. The choice of study object is based on the airline?s desire to have its cost accounting system evaluated. During the analysis we have identified a number of points where the current cost accounting system does not correspond to its intended purpose. These points include significant groups of costs not being considered in the current system, potential over capacity is not visible and logic connections between distribution keys and the use of resources are sometimes lacking.

The aim of this essay is to examine the handling of plastic waste on a local level in the three municipalities of Gothenburg, Malm? and Stockholm. This is achieved with the help of guidance within the theory of Multi-level Governance. By applying the EU directive 2019/904, about disposable plastic, and examining the global plastic problem, the efforts to promote sustainable use, and recycling of plastic, is analyzed. The method involves a qualitative content analysis, where the 2022 waste plans of the three municipalities, ?Sveriges handlingsplan f?r plast? by the Government Office, and the 2019/904 EU directive constitutes the base of the study.

Success in treatment with platinum-based chemotherapy against different types of cancer tumors is limited by side-effects such as hearing loss which can have a large impact on the individual`s quality of life. It is of great importance to continue with studies that address this complex of problems.Objective: The aim of this literature review is to investigate the impact of platinum-based chemotherapy on hearing in children and adolescents treated for different types of cancer.Method: A descriptive review of literature was made based on sources from 15 different studies on the impact of platinum-based chemotherapy on hearing in the target group.Results: The survey of the studies shows that platinum-based chemotherapy causes incidence of hearing loss by differing degree in the target group. Dosage of a platinum-based substance appeared to be the most significant factor. Treatment with both cisplatin and carboplatin was more ototoxic than treatment with only one of these. Greater risk for hearing loss was to a higher degree observed in younger children.

This report describes a final thesis done during the spring of 2008 as part of the bachelor degree in computer engineering degree at the School of Engineering in Jönköping.The client is working in the consulting business and is involved in, amongst others, work regarding information security. Within this field they perform so called Threat, Risk and Vulnerability assessments. Today these assessments are done by a predefined method, but many details are controlled by the person documenting the project. A wish was made that the implementation was standardized, it should also ease the task of estimating the need for time and money. The solution for this seems to be a software tool.

Two post milkning teat dips (PMTD´s) were compared in an automatic milking system at Kungsängen Research Farm, owned by SLU (Swedish University of Agriculture) in Uppsala. In the experiment an evaluation system was used where teat condition regarding skin and teat ends was graded according to a scale where 1 was the best score and 5 the worst. The evaluation period was almost six months in total devided into four minor experimental periods. The technician scoring the teats did not know which PMTD that was currently used. Statistical analysis showed a significant difference between the two PMTD´s regarding teat skin condition, but not regarding teat ends.

The definition of procrastination can be described as a behavior with deliberate postponement of tasks or commitments despite expected negative consequences for the individual and his or her environment. This study examined how widespread this behavior is among students in higher education in Sweden. Using a web-based survey, data was collected for analysis. A statistical program, SPSS, was used for evaluation of the collected data. The purpose of this study was to examine whether there are differences in the degree of procrastination between students located on campus versus students who do their education at distance.

Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. The CAH-concentration in trees growing on contaminated land has quite recently received attention as a cheap and effective way of assessing the extent of a CAH-contamination. The method has however, not been put into use in Sweden.The aim of the study has been to investigate whether the CAH-concentration in tree cores could be used to delineate the spread of CAH in a soil environment under Swedish conditions in different seasons.
