Metod för dosoptimering av digitalt detektorsystem i klinisk drift

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.

Att främja social hållbarhet i gröna miljöer : En fallstudie av ett projekt i Upplands Väsby

AbstractIn my study I have investigated how a constructed outdoor green environment can beused, managed and how it works. The study also investigates the concept of socialsustainability, where, for example, civil dialogue is a method to promote this. Thisinvestigation mainly gives account for the inhabitants viewpoint but also a gardenersperspective. The study focuses on the planning process of the study object, what theoutcome has been and how the users of the green environment, think about the result. Inthe process there has been a strong concern of involving the residents and others usingthe area.

Exokrin pancreasinsufficiens hos schäfer :

Exocrine pancreatic insufficiency is a hereditary disease that in Sweden is especially common in German shepherds. The Swedish German shepherd club has currently no plan of action for decreasing disease prevalence in the breed. The purpose of this study was to review existing literature about the disease and also to perform an inventory of the disease in the Swedish dog population. Special focus was laid on the German shepherd breed. The inventory was later compared to an unpublished inventory of the disease with data from the Swedish University of Agricultural Sciences from 1997. During the period 2002-06-01 to 2007-09-26 (ca 64 months) 2961 blood samples were analyzed for cTLI. 274 samples were positive (cTLI .

Kloning av möjlig promotorsekvens uppströms kloritdismutas i Ideonella dechloratans.

Perchlorate and chlorate are naturally occurring in the atmosphere, from here it sediments into groundwater and soil. The pollution is increased by discharges of perchlorate and chlorate from agriculture and paper mills. Bacteria capable of reducing perchlorate and chlorate to chloride and oxygen can be used to get rid of these contaminants. However an anaerobic environment needs to be sustained in order for this reaction to be used. For this reduction to work in an aerobic environment as well, a greater knowledge of the reducing enzymes, regulating factors and their corresponding genes is needed.

Finns det någon här som kan ha en teori om vad det hela kan bero på? : En netnografisk undersökning av diskussionsforumet på träningssajten Funbeat

The purpose of this study is to explore the Swedish site Funbeat which is a space dedicated to people who share an interest in exercising in general, and running in particular. By applying a netnographic analysis, I will investigate if Funbeat matches the criteria of a participatory culture and how the members manage to establish a collective intelligence within the community. In order to achieve this, I will analyze the interactivity between the participants which occurs in discussion threads concerning injuries related to running, in the sites discussion forum. The results will then be discussed in relation to previous research within the field for participatory culture, collective intelligence and interactivity.The outcome of the study revealed that Funbeat can be regarded as very good example of a participatory culture. By each member sharing their individual knowledge in matters regarding injuries, a collective intelligence was established.

E-böcker och bibliotek. En diskussion kring den digitala beståndsutvecklingens möte med en gryende e-boksmarknad

In Scandinavia the general idea of the Bronze Age society is that it was organised as chiefdoms. The model for what they looked like is taken from the anthropological studies of the Polynesian chiefdoms. The aim of my study is to investigate a Scandinavian Bronze Age feature, known as cairns mainly containing fire-cracked stone. This is compared with how people in different Polynesian chiefdoms, looked at similar remain. This is done to get a background for new ways of interpretation of such remains.

Växters upptag av spårämnen från rödfyr : ett odlingsförsök vid tre rödfyrshögar i Västra Götalands län

Burnt alun shale and lime is the residual product that was formed when alun shale was used as fuel to convert limestone to quick lime. The material contains arsenic, vanadium, molybdenum, cadmium, nickel, lead, and uranium among other elements. The aim of this paper is to examine the uptake of trace elements in vegetables grown on burnt alun shale and lime to determine whether or not the surrounding environment and humans are exposed to these elements by eating plant products. A cultivation trial was carried out where onion, carrot, and lettuce were grown on three mounds of burnt alun shale and lime in the Falköping area in Sweden. The treatments were burnt alun shale and lime mixed with peat, only burnt alun shale and lime, and a reference soil. The reference plots were natural soil mixed with peat adjacent to the mounds.

Fjällfåglar : En jämförande studie från dal till topp i ett nordligt och sydligt svenskt fjäll

Title: Mountain birds ? a comparative study from valley to mountaintop in a northern and southern Swedish fjeld  Author: Kristian Zackrisson Abstract Main aim in this study was to increase the knowledge about birds in the Swedish mountain area. Three questions were asked: 1) Which bird species can be found during the breeding season along a low mountain slope from a forested valley to a mountaintop with bare mountain environment? 2) Do the number of species and individuals differ in different elevation zones? 3) Is the composition of bird species along a low mountain slope the same in the Kebnekaise mountains inLaplandand the Grövelsjön mountains in Dalarna? Bird census in two study sites located in the Kebnekaise mountains and the Grövelsjön mountains and subsequent analysis of the results from the bird census was the main parts in this study. Totally 20 bird species were found along a low mountain slope in the Kebnekaise mountains.

Recensioner och Nätgemenskapskvalitet : En studie om metod för betygsättning i spelrecensioner och dess inverkan på produktengagemang och nätgemenskapskvalitet.

The goal of this essay was to study if the way gaming review sites presented their review evaluation has any influences the level of product involvement in the users it attracts. The assumption we did during the essay was that there was a connection between user?s level of product involvement and the quality of the community. To test this assumption we started out by performing observations on the comment sections in three gaming news sites which varied in their method for evaluating games. The result of these observations showed a significantly higher community quality in one of the websites.

Att leva i en aktiv värld - svenska och danska barns umgänge med pedagoger i en virtuell värld

In my study I have participated at the Fifth Dimension / Active Worlds site in Villa Gymnastiken in Ronneby, where I have worked both as an assistant to the project leader and as a researcher, but also as a participant together with the children. The children are working in a virtual world called Femtedim, created in a internet-based program named Active Worlds Education Universe. The Femtedim-world are bridging together two physical worlds in Ronneby and Copenhagen. My main focus is on an intervention that occurred in the 12th of March when the research-team in Copenhagen, which runs the project in Denmark, decided to create a new challenge for the children since some of them started to get bored. They added gravitation to the Femtedim-world, which lead to a few different reactions among the children. Most of the children didn´t like it and were very hostile towards the idea that they would not be able to fly around freely in the Femtedim-world.

We examine the awareness of Employer Branding as a tool to break gender patterns in female and male dominated administrations in three Swedish municipalities. Six recruiters people were interviewed, including three pre-school managers and three managers of technical administrations, to see if there are any differences or similarities between the organizations? Employer Branding to break gender patterns. In addition to the interviews, the Web pages of these three municipalities were investigated through a contextual perspective.We found that our interviewees do use Employer Branding, but that they were not necessarily aware of its? meaning.

A comparison of commercial scent lures in attracting Raccoon dogs (Nyctereutes procyonoides)

The invasive species raccoon dog (Nyctereutes procyonoides) is currently under establishment Sweden and it is vital to discover invading individuals to prevent colonization. The use of wildlife cameras to discover dispersing raccoon dogs have been implemented in the north-European raccoon dog management program. In this study, I test the ability of four commercially available scent lures to attract raccoon dogs to camera stations. The study was conducted in the Åland Islands where raccoon dogs are abundant and the results could improve the effectiveness of the camera stations used in the program. I used 12 sites with five camera stations in each and tested the four lures and one control with no lure in each site.

En retrospektiv epidemiologisk studie om hudproblem på dobermann :

It is a well known fact today that suffering due to skin disorders is one of the most common causes to veterinary calls. For the Doberman breed included in the group of working dogs, the frequency and distribution of the different skinrelated diagnoses that causes visits to the veterinary clinics remains undocumented. The purpose of this study was to evaluate the frequency of skinrelated problems causing veterinary visits of Doberman at four different veterinaryclinics in Sweden retrospectively, and compare these results with dogs in general and three other working dog breeds with the help of information collected from Agria - a Swedish animal insurance company. The total amount of veterinary calls that were registered at the clinics in question during the time of the study was 2460 visits. From these, 658 visits were due to skinrelated disorders, which amount to 27%. The most frequent cause to skinsuffering was injury caused by trauma, 15,7% of the Dobermans that were included in the study were affected, the second most frequent cause was inflammatory and infectious skin problems with 12,3% followed by neoplastic changes in the skin with 7% of the Dobermans affected.
