Sammanfattning Bakgrund Stråldosen vid en datortomografiundersökning (CT-undersökning) kan vara 100 gånger större än vid en konventionell röntgenundersökning [1]. På 10 år har antalet CT-undersökningar nästan fördubblats [2], vilket också innebär att stråldosen till patienterna ökar [1]. Bröstkörtlarna är ett av de mest strålkänsliga organen och är därför viktiga att skydda [3, 4]. Material som dämpar röntgenstrålning kraftigt och som lämpar sig för strålskydd är t.ex. bly och vismut [5].

Authors: Martin Mederyd Hårdh, Frida Nygren, Daniel PaulssonTitle: Under Extreme PressureLevel: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishMethod: Quantitative content analysisPages: 38Politically motivated extremism is a common topic in the Swedish public debate ? and hence in Swedish media. The purpose of our study is to get an idea of how the media relates to the extremist groupings. On a traditional political scale, ranging from left to right, our study focuses on the Swedish extremists who figure on the outskirts of this scale; The ones who denounce the current system and opt for violence to change it.Violence is often an instrument used to get extreme political ideals in the public eye, and is seen as a threat to the Swedish democracy and the public in general. Both sides argue that the Swedish press is tendentious and treat the various extremist groups differently, airing their distrust for the media as a propaganda tool for these groups to establish themselves in the public debate.Our study consists of a quantitative content analysis where we study articles published in print by seven major Swedish newspapers.

ABSTRACT Epilepsy describes a neurologically caused condition which involves seizures. Epilepsy can be classified according to different types of causes and the nature of seizures can vary. Medication for epilepsy in dogs is limited in comparison with human medicine. Idiopathic epilepsy is the most common neurological disease and one of the most common genetic diseases in dogs. Because epilepsy has a higher prevalence in certain breeds, there is reason to suspect that it is a hereditary disease. The inheritance of idiopathic epilepsy is for most breeds not determined, except for a few variants of the disease.

Animal welfare issues are not considered as high priority in Malawi, a developing country in south east Africa, due to problems affecting the human population. In Lilongwe, the capital city, education programs are used to increase the awareness of animal welfare issues among primary school children. A study was undertaken to evaluate the knowledge, attitude and practice of animal welfare in primary school children as well as two different teaching methods for animal welfare, namely humane lessons (HL) and Animal Kindness Clubs (AKC). The gender perspective, in terms of differences in attitude towards and knowledge in animal welfare, was also evaluated as well as the link between domestic and animal violence. The study was performed in collaboration with Lilongwe Society for the Protection and Care of Animals (LSPCA). A questionnaire of multiple choice character was handed out to 249 children aged between 9 and 15 from six different schools.

SammanfattningMiFID, direktiv om marknader för finansiella instrument är ett nytt europeiskt regelverk för den finansiella sektorn som träder i kraft den 1: a november 2007. Direktivet syftar till att förstärka konkurrenskraften för den finansiella sektorn, förbättra konsumentskyddet samt inkludera hela utbudet av finansiella tjänster och produkter. Då MiFID: s införlivande i svenska lag försenades fick de svenska värdepappersföretagen under 2007 en relativt kort tidsperiod på sig att anpassa sina verksamheter till de nya bestämmelserna. Syftet med denna uppsats är att undersöka vilka svårigheter tre svenska värdepappersföretag erfarit vid arbetet med att anpassa deras verksamheter till de nya bestämmelserna i MiFID. Vi har studerat direktivet och jämfört med nuvarande regleringar samt genomfört fyra intervjuer, varav tre med svenska värdepappersföretag av varierande storlek.

Works on transparent paper, also commonly known as tracing paper, have been described as ephemeral or temporary working documents and they usually number large quantities in archival and museum collections. They have therefore previously been considered of lower priority and can be found in poor condition due to a lack of treatment or suitable storage prospects. In addition, transparent paper can be very sensitive to moisture and reacts by deformation or loss of transparency. Due to the volume of these works and the necessity of treatment, there is a call for simple and efficient conservation methods. A common solution in archives for the treatment of water-sensitive works on paper has been the use of heat-activated tissues as they can be applied without the introduction of solvents. There is little published about the use of heat-activated tissues on transparent paper and is mentioned only briefly in existing literature.

The regulatory framework for constructional calculations in Sweden did expire In January the 1.st, 2011.Since then the constructional regulatory that originally were composed by Boverket (BKR) has been replaced by new common range (Eurocodes) for the entire European Union. This transition has led to changes in existing rules and standards regarding dimensioning area in Grids and has forced a need for updating to structural Engineers.The new calculation system has caused time-consuming studies of the new rules and a proper understanding of all the advice and regulations for the entire profession.This study has been carried out in cooperation with the firm "Knut Jönson Ingenjörs AB i Stockholm?, that has been affected by this transition as all other consulting firms. The firm has requested for a calculation method of wall beams according to Eurocodes. The study's focus is therefore to clarify the rules and guidelines regarding the design of wall beams according to the new regulation.

The Swedish construction industry is dominated by men; however this is starting to change. The average age of Construction Engineers is high and approximately 40 per cent of the employees will retire by the year 2015. Currently, female engineers dominate the graduating classes of Swedish Universities but this is not reflected in the Swedish Construction industry.With so many female engineers available, why is this? Does it require a change in company culture and their condition of work to attract them? Is it the attitude towards women in the industry among the employees that has to be changed? Or is it a woman?s thoughts and prejudices of the industry that creates obstacles?The purpose of this final thesis is to describe how contracting firms in the construction industry can make themselves more attractive for female engineers. To reach the purpose, a study among salaried employees and craftsmen was conducted.

Actors deliberately change their preferences, contrary to the assumptions of rational decision models. This study shows why, and to some extent how. Preferences are necessarily ambiguous and unstable. Rationality is a regulating myth which has had a profound influence on Western conceptions of what an actor is.The aim of this study is to help individual actors understand the theoretical grounds of their actions. The analysis provides tools for examining decision methods and preference changes.

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.

This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes. Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient. In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.

Together with Attends in Aneby a thesis of 15 ECTS (credits) have been undertaken. The assignment was to develop a new incontinence product for single use. Users of the product value comfort, flexibility, softness, comfort and a discreet product. Users are for individuals with incontinence problems that usually receive the products via prescription. The product must also have an attractive price and good quality from the purchase / originator's perspective.Currently there are two models that Attends supplies, which the project intends to develop, (Slips / Briefs and Pull On's).

Extensively kept animals for meat production have the right to live in a good environment. Cattle (Bos Taurus) as social animals live in small herds in the wild. When holding animals extensively new problems have arisen regarding human ? animal interactions. One welfare problem is to be able to come close enough to the animals to investigate their health condition.

In recent years many cities have seen an increase in bicycle traffic. This is a development that benefits both the environment and the individual cyclist. When the need for bicycle parking is not met several problems arise such as an increase in bicycle thefts, jammed sidewalks and a decreased interest in using bicycles. My aim with this paper has been to answer the question of how to create parking facilities in an urban environment based on cyclists' needs. Through a literature survey, following the method "Trattmodellen" (the funnel model) the question has been answered and divided under the headings cyclist, bike, bicycle racks, bicycle garage and bicycle operators and hosts.

Objective: The aim of the study is to describe pupils' understanding of the mathematical concept of function. How do pupils define the concept of function? What images of the concept of function evoke when they solve tasks, which involve identifying and constructing functions?Theory: A student's thinking about a mathematical concept depends on more than just the formal definition of the concept; therefore Tall and Vinner introduce the term concept image to describe the role cognitive structures play when students learn about concepts. The cognitive structure includes all mental images, associated properties and processes that an individual associates with a given concept. According to Sfard, an individual's understanding of mathematical concepts may have different character: an operational conception, where a concept is conceived as a process and a structural conception, where the given concept is conceived as an object, that is, as a whole.Method: 16 pupils at the Science Program at two different upper secondary schools inSweden answered a questionnaire on the mathematical concept of function.
