Afasi-vänlig information : inför funktionell undersökning av språk med magnetresonanstomografi (fMRI)
Functional Magnetic Resonance Imaging, fMRI, can be used for analyzing brain activity in subjects performing language tasks. The purpose of this study was to develop aphasia-friendly information adjusted to aphasic subjects participating in fMRI studies. The objectives were to investigate if adjusted information was important for the ability to perform language tasks and if the information could be used for different types of aphasia.Sixteen aphasic subjects participated in the study, six of these underwent fMRI. The participants varied in grade and type of aphasia. They had Swedish as their native language and were aged between 26 and 89, mean 57.
Revision av gränsvärdena - En studie om hur svenska revisions- och redovisningsbyråer skulle påverkas av tillämpning av EU-direktivens maximala gränsvärden för revisionsundantag
Background: Currently Sweden has the possibility to like other EU countries raise the limits of statutory audit, but have chosen significantly lower limits. The reform was adopted in 2010 and only applies to smaller companies and there is great pressure for the limits to rise in future. This would enable Swedish companies to compete on equal terms in Europe. Aim: The aim of our study is to investigate the impact of the removal of the statutory audit for smaller companies from audit and accounting bureaus perspective and also the possible impact if the limits were to rise. Furthermore we want to explore how the supplies of other financial services have developed as a result of this.
Surgical stress response in dogs diagnosed with pyometra undergoing ovariohysterectomy
The aim of this study was to investigate the intraoperative surgical stress response in dogs undergoing ovariohysterectomy and to compare acepromazine and medetomidine as premedications. 15 dogs diagnosed with pyometra were used in this study. Blood pressure and heart rate were used as parameters to measure surgical stress response. The surgery was divided into four phases. Phase 0 was the period 10 minutes before the skin incision, phase 1 was skin incision and opening of abdomen, phase 2 was manipulation of uterine horns, ligation and transection of mesovarium and phase 3 was ligation of cervix, removal of organs and closing the abdomen.
The results showed that phase 2 was the most intense phase of surgical stress, regardless of which premedication the dogs received.
When acepromazine and medetomidine were compared the results showed that within phase 3, all dogs that were given medetomidine had higher blood pressure compared to dogs that were given acepromazine.
The dogs that were given acepromazine had higher heart rate than the dogs that were given medetomidine in phase 0, phase 2 and phase 3.

Plafondmålningar - Arkitektförbundet Måleri på duk, Skadefenomen och åtgärdsproblematik
The concept of large paintings includes panoramas, cycloramas and other paintings thatin size exceeds the normal magnitude of wall hung paintings. When these large paintingsare mounted in the ceiling, they are referred to as plafonds. When they are performedon canvas, certain kinds of structural distortions and stress occurs. In addition, becauseof their size and mounting high up in the ceiling, plafond paintings are often difficult tohandle, which leads to less or no maintenance. A plafond may therefore be left withoutattendance for many decades.This thesis has its focus on what happens with plafond paintings on canvas when they areexposed to gravitational forces, and the problems involved in restoring large paintingsmounted in the ceiling.
Mångbruksplan inriktning vilt och viltvårdsanpassning av skogen
This multiple use forestry plan is made on the property Basunda which is located in the southern parts of the province Östergötland. The owners of the property today are Jonas and Ulrik Saanum, but it has been in the family since their grandfather bought it 1933.
There is a slaughterhouse on the property in which they take care of domestic cattle and animals from the forest. Jonas and Ulrik are also dedicated hunters. These are the two reasons to why the focus is wildlife and wildlife management.
The question at issue of this work is simplified: what demands does the wildlife have; and how will the owners be able to fulfill these, what changes in the forest management must be made and will these changes result in a different budget, compared to the ordinary forest management.
This work is based from a freshly made forestry management plan. I based my fieldwork on this plan, but made my own management proposals, that would benefit the game.
Experience of quality of life among women who have undergone breast reconstruction after mastectomy
Background: In Sweden around 6500 women suffer each year from breast cancer and during lifetime every tenth women is affected. Mastectomy (removal of part of or the whole breast) is carried out mostly in purpose to remove malign tumours or in prophylactic purpose. The breast can be rebuilt through breast reconstruction. Method: The result analysis was based on nine articles. A Manifest content analysis was used and data from the articles where divided into themes and patterns, on the basis of these categories were created.
Växters förmåga att ackumulera metaller : Vass, bredkaveldun och gäddnate i Bergviks dagvattendamm
AbstractSurface-water includes different kinds of pollutants from traffic and roads. To prevent these pollutants to reach nearby lakes one can construct surface-water ponds on locations with heavy traffic. At Bergviks shopping centre in Karlstad, two ponds, one smaller and one bigger has been constructed in order to decrease the pollutant pressure from the receiving waters of Kattfjorden. Several heavy metals are essential for plants and animals in low concentration but when they occur in higher concentrations, they become toxic to the organism. The larger pond at Bergviks shopping centre has a sedimentation function so the heavy metals sink to the bottom thereby not releasing directly in to Kattfjorden.
How to future proof a Business Model : Capture and capitalize value in the field of Urban Mining
Context: During the 21st century several alarming reports have been published that deals with the depletion and pollutant of the earth by human interference. The earth is an ending resource and so are the mountains and bedrocks which are continuously mined in order to harvest its minerals. The idea behind Urban Mining is to (re)invent processes enabling further purpose for materials both from old deposits and new products providing secondary raw materials and energy. This thesis aims to investigate the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between product-/service systems, economic growth and environmental stewardship in the context of Urban Mining as an approach. With the innovation of processes, technology, business- planning and creation in focus.Objective: How to future proof a business model for Urban Mining by the usage of business model design.Method: This thesis will be conducted using a case study approach, meaning that it will incorporate qualitative, exploratory and descriptive characteristics - aiming towards enabling both applied and fundamental research.Results: The result evaluates the business model element differences between traditional C&D industry and Urban Mining industry.
Långsiktig förändring av fosforhalt och skördenivåer för jordar med höga P-AL-tal : en analys av försöksserien "Exploatering av höga fosfortillstånd"
The field trial Exploatering av höga P-AL-tal (Exploiting P in heavily P dressed soils) started in 1982-1983 and included seventeen study sites placed across Sweden.
Each site included three treatments, one unfertilized control (A), one aiming at replenishment of harvest removal, i.e. fertilized with 15 kg P ha-1 year-1 (B) and one over-fertilized (C) with 30 kg P ha-1 year-1. In this thesis data from the five longestrunning study sites are analysed based on four hypotheses. The hypotheses stated
that in soils with high P-AL values and a pH over 6.0 P-AL will not decrease over time in the control (A) or in the replenishment treatment (B), that P-AL and P-HCl
in the top soil will increase at all sites for the over-fertilized treatment (C) and that yields will not decrease as long as the P-AL is above 12 mg P 100 g-1 soil.
My conclusions from the analysis of data from the selected sites are as follows:
- A pH above 6.0 cannot guarantee a stable P-AL value in an unfertilized
but phosphorus-rich soil.
- The P-AL of unfertilized soils decreased faster at lower soil pH than at
higher pH.
- In the replenishment treatment (B) the rate of P-AL decrease seems to fall
at a pH of 6.5. However, the influence of the soil type cannot be ignored.
- P-AL and P-HCl did not increase in all over-fertilized treatments.
Yngre kvinnors upplevelser av att få en bröstcancerdiagnos och livet därefter
Background: Breast cancer is one of the most common types of cancer in the world and it usually affects elderly women. However, there are between 600-700 cases per year in Sweden where women under the age of 45 are diagnosed. Removal of the breast or part of the breast, hair loss, fatigue and nausea as a result of the breast cancer treatment has an emotional and physical impact on the women?s lifeworld. The nurse should build a relationship with the women to identify and meet their needs. Aim: To describe younger women?s experiences of getting a breast cancer diagnosis and life afterwards.Method: Four biographical books were analyzed to match the aim of the study.Result: The findings were that the women experience similar thoughts and feelings when it comes to living with a cancer diagnosis.
Elementkoncentrationer i gran utmed en markfuktighetsgradient :
One key factor in silviculture today is sustainability. In order to achieve sustainability it may be important to restore lost nutrients to the forest after clearcutting. In order to calculate the removal, you need to know how much of different elements you will find in different tree compartments. The aim of this study was to investigate if the concentration of elements in different tree compartments of spruce (Picea abies (L.) Karst) were related to the moisture conditions of the site. Five plots at Risfallet (60º 21´ N, 16º 13´ E), was placed along a moisture gradient in a 40- year spruce stand.
Laktester för riskbedömning av förorenad mark :
Using leaching test is a way to get a picture of pollutants retention and leaching in a risk assessment on contaminated land. There are several different types of standardised leaching tests today, where the natural leaching processes are speeded up to make it possible to predict the leaching of pollutants. These leaching tests have been developed for waste and there are no specific guidelines on how to judge the results from the tests, when making a risk assessment on contaminated land. This work is an investigation on how to use leaching test in this type of risk assessments. The strengths and weaknesses of the different types of tests are discussed.
Depending on what type of information you want from your leaching test, different types of tests are suitable.

Hur kan organisationer gå från att vara samlare av informtion till att bli nyckeltalsanalytiker? : En fallstudie på Trafikverket
In 1993 the internal market within the European Union was formed and ensured free movement of goods, services, capital and people. This led to the removal of trade barriers between members of the European Union. When opening up for competition, price differences between countries decreased and more jobs were created. A single currency was introduced by eleven countries in 1999 with the goal of reducing transaction costs, eliminating exchange rate risk and to further simplify trade. In 2001 Greece joined the collaboration and introduced the euro.
Fl?ckreducering ? Bl? Vinranka En j?mf?rande studie av tv? efterbehandlingsmetoder vid reng?ring av glaserad keramik
This study explores the effects of two different post-treatment methods on stain reduction in glazed creamware from the late 20th century. The objects stains have been characterized by type one and type two stains which is the result of prolonged contact with food residues, were subjected to the same initial stain reduction. The two post-treatment methods examined are soaking the objects in deionized water and surface rinsing with deionized water. The comparative analysis included photographs under normal and UV-light exposure to assess stain visibility, weight measurements before and after treatments to monitor the absorption and evaporation of liquids, and observations throughout the experiment. The results revealed that while type two stains showed significant alterations after treatments, specifically after soaking, type one stains remained unaffected by both methods.
