SAMMANFATTNING Mitt examensarbete utgör ett led i Nordiska Genbankens (NGB) uppgift att skapa en nordisk s.k. ?core collection? av rabarber, Rheum rhabarbarum L. Samlingar finns även i våra nordiska grannländer Norge, Finland, Danmark och Island. I Sverige har ett insamlingsarbete av rabarber pågått under åren 2002 och 2003 för att komplettera en äldre samling.

The main objective of this study is to divide a number of colorectal cancer cases into subgroups based on their molecular features using cluster analysis. The data used is supplied by a research group at Pathology, the Department of Medical Biosciences, Umeå University, and consists, after some preparation, of 455 observations which is a larger data set than many similar studies. The molecular variables that the clustering is based on are CIMP (CpG Island Methylator Phenotype), MSI (Micro Satellite Instability), BRAF- and KRAS-mutations. These are categorical variables and consequently the clustering method used is PAM (Partitioning Around Medoids) which is particularly useful with data on diverse variable level. The final analysis results in four subgroups that are represented by different combinations of attributes on the aforementioned variables.

Planet rendering plays an important role in universe visualization and geographic visualization. The recent tools and methods allow better data acquisition, usually with very high resolution. However in computer graphics, there is always the limitation on the resolution of geometry and texture due to numerical imprecision. Not many applications can handle high resolution data effectively.This thesis introduces, Implicit Surface Scene, a level of detail scene management inspired by dynamic coordinate system and SCALEGRAPH? which change over time depending on the current camera position relative to the planet surface.

The purpose of this thesis is to study and determine how working in cross functional teams can generate value in an effort to facilitate innovation. An inductive scientific perspective is chosen as the research approach. A single case is investigated with the theoretical framework based on Resource Based View, Intellectual Capital, Innovation theory and theories concerning Cross Functional Teams. The empirical material has been collected through primary data; surveys, interviews and secondary data; literature, websites and further complementary data. The practice of using Cross Functional Teams will enhance organizational learning, knowledge transfer, increase communication and innovation, which in turn will increase the speed and performance of the new product development process.

Det senaste halvåret har Sveriges styrränta sänkts kraftigt för att stimulera den avstannande ekonomiska aktiviteten. Enligt makroekonomisk teori ska en ökning respektive sänkning av räntan påverka konsumtionen likvärdigt, i respektive riktning. Men fungerar verkligheten som den ekonomiska teorin påstår? Tidigare studier på utländsk data har kunnat påvisa ett asymmetriskt räntesamband medan forskning på svensk data saknas. Med hjälp av en felkorrigeringsmodell, skattad med Engle-Grangegrs tvåstegsmetod, testas detta.

This master?s thesis studies library teaching at two university libraries, Freie Universität Berlin in Germany and Södertörn University in Sweden. The aim of this paper is to study views on information literacy, how these views affect teaching practice, and how the teaching of information literacy is connected to, on the one hand, German and Swedish learning culture and, on the other, the local community of practice at the studied university libraries. The theories applied in this paper are learning culture and community of practice as developed in the works of Judith Ricken and Etienne Wenger. The methods that have been used are qualitative, semi-structured interviews that were conducted at both university libraries.It was observed that the teaching practices were highly connected to learning cultures.

The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.

The aim of this thesis is to examine the occurrence of Cosmetic Earnings Management (CEM) among Swedish companies. CEM refers to the small upward rounding of reported net income to reach cognitive reference points. Important cognitive reference points are multiples of ten (N*10^x) of reported net income and rounding towards these has been documented in other markets around the world over the last 20 years. The occurrence of CEM on the Swedish market is studied using digital analysis, frequency testing and Benford's law. Firstly, reported net income of publicly traded companies between 1996 and 2010 is examined.

Using the example of 55 former towns in Greater Poland, the author investigates the belief thattowns formerly deprived of town privileges are the most likely to be qualified as future formalurban entities. This paper approaches the subject of urban deprivation and restitution with amultiaspectual study of the concept of urbanity. Since a preponderance of Polish degraded townspossess a prominent urban physical structure, the study focuses mainly on urban morphology as acontributing factor to urbanity. Other approaches include the central place theory, demographicconditions and the role of urban perception. Taking into account Poland?s shifting geopoliticalhistory the study also seeks to identify and explain spatial patterns of varying degrees of urbanityamong the studied towns.

The explosion of information technology has given users direct access to an ocean of information. Increased availability puts increasing demands on the ability of students and researchers to search for, filter, and structure information. In response, the role of the research library has shifted from being primarily an information resource to being an educational resource with a focus on teaching users what is known as information literacy. This thesis is a study of user-education at the Karolinska Institute Library KIB, the largest medical library in the Nordic countries. KIB has invested significant resources in developing user-education, and has a full-time user-education developer and a formal pedagogical platform for user-education.

Claw health has been recorded by claw trimmers at trimming in Sweden since 1996, but data was then captured at each AI association. From 2003 data was captured by central scanning and entered directly to the national cow data base at the Swedish Dairy Association (SDA). This reporting was introduced because SDA wanted to be able to use these records to improve dairy cow claw health by breeding. It is desirable with cows that have healthy claws, because poor claw health can contribute to impaired production and fertility. The claw health report begins with some information about herd, claw trimmer, date et cetera and continues with the part where the claw health is recorded. Here the ID of each cow is filled in and on the same row the conditions for dermatitis, heel horn erosion, sole haemorrhage and sole ulcer are recorded as no lesion (blank), slight lesion (/) or severe lesion (X).

Vi blir allt mer beroende av informationssystem och den information de producerar. Detta medför ett ökat behov av att denna information är av hög kvalité. Om det är tveksamhet vilken kvalité det är på in- och utdata söker vi ytterligare information för att bli övertygade. Olika krav ställs på informationssystemen för att användarna och system skall fungera tillsammans på ett tillfredställande sätt. Genom systemförvaltning finns möjligheter att påverka förutsättningarna för användarna att skapa data men hög kvalité.

This thesis assignment at C-level is focused on calculation models and prediction methodswhish can be used in the stage we call ?prospecting? of possible windmill locations. Thelocation is southeast of Halmstad at the Farm ?Stjernarpsgods?. The rapport has two mainareas directed towards this task.

The purpose of this paper is to test a procedure that would be useful for a certain, more final purpose. Assume that you want to know if the differences in the result of a certain effort in health care have any connection with differences between the life situations of the patients. This would be easier to investigate if the life situations of the patients had connection to the easily available variable Health Care Cost (in Swedish VK). In that case the searching for connections between VK of patient groups and the result of health care efforts would be sufficient to gain knowledge of possible connection between health care efforts and life situations. Thus that is the final purpose.

Purpose: The main purpose of this study is to study the 45 funds, divided into three differentdivisions, then the result will provide a greater understanding of how returns change with ahigher risk.Methodology: The study is based on a quantitative approach. The survey was conducted bygathering raw data from databases and secondary data from literature, printed and electronicsources.Theoretical perspectives: The study is based on the theory: the efficient markethypothesis, which argues that future returns can not be calculated as the market is fullyinformed. The study is therefore studying historical yields.Empirical foundation: Empirical data are acquired from www.morningstar.se, andtherefore also treated on this page. The material is then divided into documents and time axes.Conclusions: The study has shown that high-risk funds give a higher percentage returns thanmedium-and low-risk funds. However, does not imply a higher risk automatically earn ahigher return when the low-risk funds have shown a higher yield than medium-risk funds.
