The county of Dalarna is at present carrying through a process of digitalization where traditional x-ray film is being replaced with digital detectors. Earlier used methods for dose optimization turned out not being sufficient. This report presents a method to harmonize dose levels between x- ray sites equipped with Fujifilm imaging plate systems. An exposure index, S, related to the dose level of the examination is computed to every x-ray image. S turned out to be inversely proportional to the detector dose used at the examination.

In Sweden, there are limits to how much leachable substances waste must contain in order to be deposited as hazardous waste. Fly ash from waste incineration often end up over the limit, mainly due to the chloride content. Fly ash is therefore often deposited abroad. The purpose of this study was to investigate the possibility to handle fly ash locally. To clarify how the law is applied, environmental reports and permit documents from ten waste sites with permission to deposit fly ash were studied.

AbstractThe purpose of this study is to explore the organizational culture within the corporation The Body Shop. I have been working with two different question formulations. The first is to answer how the culture can be described. To answer this I have been using Edgar H. Scheins theory of cultural levels.

The aim of this Masters thesis is to examine ideas used to legitimate Swedish digital libraries, with a focus on the cultural heritage, their relation to cultural policy and an eventual crisis within the latter. Which ideas are linked to digitalisation? How do the arguments for creating digital libraries differ between central actors? How do the digital libraries relate to cultural policy and an eventual legitimacy crisis? These are the questions this thesis seeks to answer. The theoretical starting-point consists of a legitimacy discussion and its connection to Swedish cultural policy. The method used is idea analysis.

Abstract.The levels of dioxin and comparable substances rose to a large extent in our environment during the second half of the 20'Th century. This was the result of the synthesis of, and careless usage of these substances in cooling fluids, hydraulics, pesticides etc. Background levels of dioxins and furans in sealed samples prior to this era suggest that former sources of these substances existed. Salt glazing is a method of adding a smooth acid resistant exterior to stoneware ceramics. The technique has been in use since the 16'Th century, maybe even earlier than that.

This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger district heating plant. Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large district heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.

High levels of ammonia in grass silage have been up for discussion by Swedish advisers. One reason is that it is more difficult for the rumen-microbes to utilise high levels of ammonia. A low level of ammonia is also good because if the cattle can use more of the protein in the silage, they don?t need so much protein concentrate. That is very good for the economy at the farm, and it is also good for the environmental problems caused by high levels of ammonia. In this project, 24 samples of silage have been taken at 20 different farms in the south west of Sweden.

The aim of our study was to increase the awareness of the importance of implementation when a policy document is widely introduced. We wanted to examine how a political decision was implemented on different levels in a social care administration. We also wanted to examine the discretion related to the decision on different levels in the organisation, and if the work is followed up. The theoretical frame of reference in our study is Vedung?s implementation model and Lipsky?s theory about street-level bureaucrats.

The Swedish FSC standard (Forest Stewardship Council) is a level standard used to certify forestry. All the major Swedish forest companies are using the FSC standard, and approximately 50% of the Swedish forests are FSC certified today. In the essay six items within the chapter on environmental issues and biodiversity are examined: the proportion of protected forest, the proportion of annually burnt clear-cut stands, the number of trees with large diameter, the amount of dead wood, the proportion of deciduous trees within a stand and the proportion of deciduous-dominated stands. The FSC standard states a level for all items, and the purpose of the essay is to analyse whether these levels are supported by research within the field of conservation biology. The validity of the levels of the six items is them discussed to evaluate whether changes are required to the next revision of the FSC standard.

In Sweden live badgers are used in tests in order to train and prepare earth dogs for hunting underneath ground. This has for several years causeddebate concerning the welfare of the badgers. It is questioned whether the purpose of the dog training, i.e. to reduce injuries in both dogs and prey, is worth the suffering that is reflected on the badgers. The aim of this investigation was to study 1) stress levels in badgers when used in earth dog training, 2) if the stress load differs when the badgers are exposed to dogs with varying aggression levels (low, moderate, high).

The aim of this study was to find possible relations between behaviour and physiology for puppies during different parts of a puppy test. This work deals mainly with the physiological part of the study. Thirtysix puppies, från five litters, were tested in a behaviour test where heart rate was measured and saliva samples were collected before and after each part in the test. Saliva and urine samples were analyzed for corisol concentration as an indicatior of stress. The tests were performed during two consecutive days in the breeders' home when the puppies were seven weeks old. In addition, heart rate and cortisol levels were also measured in the bitch since we were interested in finding out if there were any relations between physiological levels in bitches and puppies.

Pyometra (chronic purulent uterine inflammation) is a common disease in middle-aged and older intact bitches. The disease most frequently occurs in metoestrus and previous research studies have shown that both hormones and bacteria are involved in the development of the disease. Analysis of the blood levels of prostaglandin metabolite 15-keto-13,14-dihydro-PGF2? (PG-metabolite) has previously been shown to be clinically useful in the differentiation of canine uterine diseases such as pyometra and mucometra. The PG-metabolite concentration has also been correlated to severity in pyometra as determined by hospitalisation length. The purpose of the present study was to investigate if blood levels of PG-metabolite can differentiate uterine diseases such as pyometra from other diseases in female dogs.

The effect of total dietary fat on the blood lipid profile: a reviewFat consumption has increased in Sweden in the 21th century, probably due to the advancement of the diet low car high fat (LCHF). Also, cardiovascular disease is the leading cause of premature death in Sweden. Various blood lipids are used to evaluate the cardiovascular disease risk; total cholesterol, LDL, HDL and triglycerides among others. High levels of total cholesterol, LDL, triglycerides and low levels of HDL are believed to increase the risk. The purpose of this review was to examine the effects of high-fat-diet on blood lipids, cholesterol, LDL, HDL the ratio between LDL/HDL and triglycerides through a systematic review.

The essay studies the relationship between communication and organizational culture; to determine if there are any cultural differences between the management of an organization and its employees and to examine how a difference can affect the communication of organizational policies. A case study, where the public school was examined, was used to answer the research question, and interviews were held with relevant people on different levels in the organization.The interviews were analyzed with the theoretical frame of reference as a benchmark. Cultural differences could be identified between different levels in the organization and between the two schools studied. The differences affected how and why people communicated but not how well the respondents understood each other.Keywords: Organizational culture, subculture, Organizational communication, affects, hierarchy..
