Genetisk studie av inavel och fertilitet hos hund :

Inbreeding, the mating of related individuals, has been the one dominating breeding strategy for dog breeders during the last 200 years. However, its negative effects on fer-tility and other fitness traits, a phenomenon called inbreeding depression, have been ignored in the quest of perfect unity in conformation or performance. The purpose of this study was to test the hypotheses that litter size is reduced as a consequence of in-breeding, affected by both the inbreeding coefficient of the dam and the litter and that a rapid increase in the inbreeding coefficient affects litter size more than a slower rate. Data were collected from the Swedish Kennel Club registry of origin. Breeds included in the study were the Bernese Mountain Dog, the Cocker Spaniel, the Golden Retriever, the Rottweiler and the West Highland White Terrier.

Cultural Capital? - On the view of culture and cultural policy in Lund's application process to become Sweden's European Cultural Capital of 2014.

The aim of this Master's thesis is to examine the ways in which culture and cultural policy are being articulated in the process of Lund's application to become Sweden's European Cultural Capital of 2014.I have used Dorte Skot-Hansen's three cultural political rationalities: the humanistic-, the sociological- and the instrumental rationality, as well as and Jenny Johannisson's extension of those into three cultural-political discourses, as sensitizing concepts in my analysis. The questions raised are: How are the three rationalities/discourses articulated in the chosen central documents and in the process surrounding them? Which themes and arguments dominate the chosen documents?The main objects of my study have been four texts that have been produced in the applicationprocess: a Prestudy, a Plan of action, a Broschure and a Cultural policy. Along with them local political protocols, newspaper articles and other related material have been used. The research method applied was a qualitative eclectical textual analysis with emphasis on the content and on tracing the way the rationalities were expressed in the material.The rationalities were all found to be articulated in the four texts.

Studier av mjölkbarhet automatiskt mätt i mjölkningsanläggningar :

Milkability or ease of milking, has higher importance today for Swedish dairy cattle producers after the introduction of milking parlours and automatic milking systems. Milkability is the cow?s ability to quickly milk out and be completely milked. There are several measures of milkability available. Today the farmer measures the traits subjectively in relation to the conformation scoring of the cow 30-270 days after her first calving.

De sociala medierna och rättssystemet

 The main purpose is to investigate the main fea-tures of the discourse in the social medias about the legal view on cimes and criminals.                                                The special questions that are investigated are:1)    What specific features characterize the discourse in the social medias?2)    What are the legal restrictions for the freedom of speech on the Internet?3)    What attitudes can you find among lawyers towards the discourse in the social medias?4)    Are there grounds for presuming that the discourse in the social medias can effect the judgement in a special case?         .

En grav är mer än bara en grav... En metodutveckling av tafonomi som redskap att förstå olika anläggningar med djur

This paper deals with a taphonomic study of contexts with osteological material of dog (C. familiaris L.) from the Mesolithic and Neolithic of Sweden and Zealand, Denmark. The general aim is to develop and test a method to try to understand the activity behind and define specific archaeological structures. My questions also regards to wether a taphonomic analysis of the material could be used to identify treatments as wrapping and contraction of the dogs, but also dismembering and other preparations of the body. The study focuses on the relation between the space of decomposition, disarti-culation of the joints, evidence of wall effect, cutmarks, weathering and signs of postdepositional arrangements.The analysis is based on contexts from the materials Hornborgasjön, Vedbæk, Skateholm I and II, Sjöholmen, Ertebølle, Bökeberg, Bredasten, Löddesborg, Bergsvägen and Röekillorna, dating from early Maglemose culture to Neolithic Battle axe culture.The analysis shows that a closer study of taphonomic processes can be used to identify different structures as graves, offerings, religious and non religious contexts or parts of animals, probably put into the ground as waste.

I morgon blir det börsfall! : En studie om hur olika börser påverkar varandra i fördröjning

SammanfattningTitel: Imorgon blir det börsfall! En studie om hur olika börser påverkar varandra i fördröjning.Seminariedatum: 28 maj, 2012Ämne/kurs: FEK 61-90 Kandidatuppsats i Corporate Finance, 15 poäng Författare: Stefan Koch, Malin Molin Handledare: Hans MörnerExaminator: Kent SahlgrenNyckelord: Anomali, anomalier, veckodagseffekt, måndagseffekt, index, korrelation, S&P 500, OMXS 30, effektiva marknadshypotesenSyfte: Att undersöka ifall en eventuell anomali på det svenska OMXS 30 indexet eller det amerikanska S&P 500 ger en effekt på nästföljande dag på det motsatta indexet. Om en veckodagseffekt kan påvisas och den fördröjda korrelationen mellan indexen är tillräckligt stark kan metoden användas för att generera överavkastning.  Metod: Vi använder oss av en kvantitativ ansats för att med hjälp av statistiska metoder svara på vår problemformulering. De metoder vi har använt är hypotestestning av medelvärden med ett z test, beräknat korrelationskoefficienten mellan de två indexen och utfört en multipel regressionsanalys med dummyvariabler.Slutsats: Genom vår analys kom vi fram till att en veckodagseffekt inte kan påvisas på någon av de två undersökta indexen. En korrelation kunde finnas mellan de två indexen, däremot går det att ifrågasätta om korrelationens styrka är tillräckligt stark att handla utifrån. För att generera överavkastning krävs dessutom att den extra avkastning som genereras med hjälp utav vår metod med korta aktieaffärer överstiger den eventuella transaktionskostnaden som uppstår vid aktiehandel, något vi starkt betvivlar att den gör..

Problematik vid analys av fastighetsbolag efter införandet av IFRS

The study describes the problems with analysis of real estate companies after the introduction of IFRS. With the introduction of IFRS (2005) and specially IAS 40 the real estate companies get the ability to appreciate its real estates to real value. With the difference in the accounting, grows the question if it has become some differences for analysts with analysis and valuation of real estate companies. We also look into how well this new standard effect the real estate companies from the view of the accounting quality and its characteristics..

Abstract:Styrdokument i musikämnet-En komparativ studie av norska och svenska styrdokument i Musikämnet i skolan.(Music Subject governing documents- A comparative study of Norwegian and Swedish policy documents in the Music subject in school)The purpose of this study is to compare the Norwegian and Swedish policy documents on teaching in the Music topic. The comparison also applies to the requirements which have been in Sweden over time. In comparison, the policy document LGR 11 from Sweden, analyzed, and the governing documents MUS1-01 and R94 from the Norwegian School.The main issue in the study is: How does the policy documents for the topic music in Sweden, compared to Norway? In order to answer the question, I compared the above-mentioned policy documents and set in relation to the musical substance is designed in Norway and Sweden.In curriculum theory treats one problem based approaches in structural functionalism, pragmatism, social epistemology and post structuralism. The starting points are then used to explore various relationships between curriculum theory and didactics.The principal researcher and proponent of curriculum theory is Ulf Lundgren.

Bostadsbranschens väg in i upplevelseekonomin : Kan fastighetsmäklarens arbete omvandlas till en säljande upplevelse?

The civilization has taken a step from the industry society to a service oriented culturewhere the physical differences between different products have decreased in value for the customers. The differentiation is more about senses, esthetical symbols and design. Modern economy is more and more focused on consuming and produce dreams and lifestyles. Maybe are we ready to face a new era; the society of experiences?Can the trend that is striving towards experiences really be adapted to all markets? This question started our quest to see how the real-estate market would be able to be adapted to this new economy.

Hårdhetsvariation i grundvatten längs Badelundaåsen mellan Leksand och Avesta

Water hardness indicates the concentration of calcium and magnesium ions in water. Water with high concentrations of these ions is described as hard water and water with low concentrations is described as soft water. Water that is too hard or too soft can lead to technical and economical problems. In collaboration with Midvatten AB, groundwater hardness in the Badelunda esker between Leksand and Avesta has been mapped, and an attempt has been made to explain the variations. For this purpose, different GIS programs, such as ArcView, ArcInfo, IDIRISI, and one geochemical modelling program, PHREEQC, has been used.

Jämförelse av icke-kryptografiska hashfunktionerför användning i hashtabeller

This report examines some common or otherwise interestingnon-cryptographic hash functions with respect to the number of collisions when used in hash tables for different types of hashkeys. The report answers which of the examined hash functions can be seen as the best performing for the chosen hashkeys. To compare the different hash functions, an experiment which studies avalanche effect behaviour is carried out. The experiments also calculate the fraction of colliding hashkeys, and the distribution of hashkeys in hash tables is studied using Karl Pearson?schi-squared test.

Stärkelsenedbrytningens betydelse för mjölkkors konsumtionsmönster och mjölkproduktion :

Feed intake in dairy cows is regulated by a variety of factors influencing hunger and satiety. One of the regulation systems includes the short chain fatty acids produced during feed degradation in the rumen. Starch can be digested either in the rumen where short chain fatty acids are produced or in the small intestine where glucose is the end product. Since glucose does not have the same effect on satiety that short chain fatty acids have, the site of starch digestion might be an important factor that affects feed intake and milk production. The aim of this study was to investigate the effects of site of starch digestion on feeding behaviour (feed intake, consumption time, and eating frequency) and milk production. Because feeding behaviour is closely connected to the cows? environment, the study also included observations of behaviour. Three different feed rations were compared.

In this study I have brought up what pupils within vocational training, with focus on upper-secondary school have apprehended about the course ?Projektarbete 100 p? (Project job 100 point). In my analysis I interviewed twelve pupils from upper-secondary school who had 20 % or more truancy during their three years of studying in upper-secondary school and achieved a result to these pupils had problems with absenteeism then primary school. The pupils agreed about the school?s existence but they need schools of practical type.

Antibiotic resistance associated with bacteria in irrigation water : a case study of irrigation ponds in Southern Sweden

The focus of this project was to characterize the occurrence of ESBL-­?producing bacteria in two irrigation water ponds in Southern Sweden. Samples were taken from two ponds nearby each other, from which analyses were made based on levels of community and individual isolates. Community samples were used for attempts for characterization of resistance patterns in irrigation water using the Omnilog PM-­?plate system. The growth of community microbiota in the presence of the following antibiotic substances was assessed; amikacin, gentamicin, kanamycin, penicillin G, ampicillin, piperacillin, trimethoprim, potassium tellurite and ciprofloxacin. Isolates were pure cultured using semi-­?selective media: LB, Rainbow Agar, mEnterococcus, 0.1 TSA and VRBD. A total of 177 isolates were isolated randomly. Each isolate was identified using the Omnilog GENIII-­?system of biochemical characterization. Further, the isolates were tested on Brilliance ESBL-­?agar for their ability to grow. Out of the total number of isolates, 30 were selected, preferably Enterobacteriaceae or Pseudomonas spp., based on their high similarity to library strain during the identification in the Omnilog-­?system. These were further characterized using Etest-­?sticks. Three selected strains were picked for further analyses using exogenous isolation for attempts to simulate horizontal gene transfer, and Omnilog PM-­?panels containing various antibiotics of interest. Selections of samples were chosen for molecular tests targeting plasmid-­?borne resistance genes CTX-­?M1, CTX-­?M2 and SHV. The method for assessing community-­?resistance patterns showed ambiguous data that was difficult to interpret; further optimization is recommended. For all tested PM-­?plates, generally greatest differences between substances were found among wells with the strongest concentration of antibiotic substance. A total of 175 isolates displayed ability to grow on ESBL-­?agar. Etests confirmed ability of isolates to resist many ?-­?lactam antibiotics and many were clinically resistant to certain substances. No plasmids were transferred during exogenous isolation. During molecular tests, a few matches were found for the CTX-­?M1 gene. Isolates analyzed with Omnilog PM-­?plates showed resistance to most compounds tested. The isolates showed greatest resistance toward penicillin G, ampicillin, amikacin, kanamycin and trimethoprim. In the study, it was established that resistance among bacteria was frequently occurring in the irrigation water, and ?-­?lactamase producing bacteria was very common. Extended studies are needed to assess the frequency-­? and occurrence of horizontal gene transfer (HGF) in this environment. Although some potential corresponding data is found, it is at this point not possible to determine whether the resistances are due to antibiotics used in veterinary medicine, human medicine or one additional reason is travel and trade. in irrigation water using the Omnilog PM-­?plate system.
