Kronisk gastroenterit hos hund med avseende på histopatologisk bild och förekomst av Helicobacter spp :

It is well known that dogs often have Helicobacter spp in their stomach. The importance of these bacteria in the development of gastrointestinal disease in dogs is still unknown. In humans, Helicobacter pylori is a causative agent of chronic gastritis and gastric ulcers. In contrast to humans, dogs seldom harbour naturally acquired H. pylori.

Betavärdet som riskestimat

As stocks have become a more common way for people to save their money, the range of financial information has had a substantial increase. To understand the assumptions that stock valuation and analysis are built upon, it is important for the reader to have an understanding for the models that are used by banks and institutions when recommendations are published.The cash flow model, which is the most commonly used stock valuation tool, is based on CAPM. This model describes the relationship between an assets return and its risk in relation to an index. The risk parameter is called the beta value and has grown to be the dominating risk factor within financial economics literature.The use of beta values has been widely discussed in the world of academics and some researchers claim that the degree of explanation brought about by the beta is so low that it should be discarded, others are faithful to the beta and believe that it still serves a purpose. As a result of this criticism other ways to calculate the beta have surfaced, models that take other factors of risk into consideration.

Det förbryllande sambandet mellan risk och avkastning : En studie av de nordiska finansiella marknaderna

Purpose: The purpose of the study is to in a comparative and causal way explore whether there is a relationship between risk and return and also how it is perceived on the Nordic financial markets.Theory: The theoretical frame of reference applied in the thesis is considered relevant inthe perspective of the study?s purpose and research questions. We have among other theories used The Capital Asset Pricing Model, The Efficient Market Hypothesis and various Behavioural finance theories.Method: The study has its starting point in a quantitative approach with a quantitative data analysis supported by secondary data extracted from Thomson Reuters.Empirics: The empirics contains regression analyses made from calculated secondary data of 240 randomly chosen companies from Nasdaq OMX Stockholm, NasdaqOMX Copenhagen, Nasdaq OMX Helsinki and Oslo Bors.Conclusion: The study conclusions show that there are both a negative and positive relationship between volatility and actual return on the investigated markets. Considering this prior statement we can conclude that the Capital Asset Pricing Model can?t correctly describe the actual relationship between the parameters investigated on the current sample.

Reporäntans påverkan på den svenska aktiemarknaden

Reporäntan som är Riksbankens viktigaste styrmedel används för att påverka landets inflation. Det har utförts omfattande undersökningar om ränteförändringar på den amerikanska marknaden. Flera forskare konstaterar att en höjning av reporäntan medför en nedgång av börskursen och vice versa samt att de finner skillnader branscherna emellan.Syfte med undersökningen är att studera om denna teori överensstämmer med den svenska aktiemarknaden. Studiens tidsperiod innefattar åren 2002 ? 2011, detta för att få med både en hög- respektive lågkonjunktur, för att på så sätt undersöka om reporänteförändringen ger en starkare effekt under konjunktursvängningar.

Likviditetsva?gen till mer informerade investeringsbeslut : En studie om sambandet mellan a?garkoncentration och likviditet pa? Nasdaq OMX.

Abstract Master Thesis in Business Administration, School of Business and Economics at the Linnaeus University, 2013 Authors: William Funseth and Tobias Åkesson Supervisor: Magnus Willesson Examiner: Sven-Olof Yrjö Collin Title: The liquidity route to more informed investment decisions - A study on the relationship between concentration of ownership and liquidity on Nasdaq OMX. Background and problem: Previous studies have shown that liquidity can explain differences in returns in corporate shares, the company's cost of capital and the valuation of the company. Based on the effects of liquidity we developed a research question concerning how concentration of ownership effects liquidity of corporate shares the studies conducted for companies listed on Nasdaq OMX during a period with major changes on the stock market and is also investigating weather other company-specific differences can explain differences in liquidity. Purpose: The study's purpose is to study the relationship between ownership concentration and liquidity, and whether other factors might explain differences in liquidity. Method: The study is conducted with a quantitative method and it?s based on data collected from 2006-2011 for companies listed on Nasdaq OMX.

Fri utfodring av halm som strategi för att förhindra stereotypier hos uppbundna kvigor :

At present indoor tethering of dairy cows is still common but is not predicted to take part of modern dairy production. When conducting scientific studies of cattle it is generally necessary to tether the animals to maintain a controlled environment. Studies confirm that tethering and confinements of cattle severely affects the development of stereotypies in cattle. The feeding regime and feeding level have an immense affect on the stereotypi level in cattle. The aim of this experiment was to study dairy heifers that had never been tethered before the start of the experiment, to evaluate the affect of tethering on the development of stereotypies and the impact of the feeding regime on the behavior of the animals. Sixteen dairy heifers were tethered in a tie stall and divided in two groups with different treatments. Heifers in treatment E were fed restrictedly with silage and treatment EH was fed with the same amount of silage but also straw ad libitum.

Nutrient effects on microorganism communities in nutrient poor soils

Better, more efficient fertilizers with great productivity and economic returns are needed, but it is important today to find fertilizers that are also sustainable. It is also important to carefully monitor their impact on the environment, including potential side-effects. In this context, the microbial communities that carry out numerous essential functions contributing to a functional ecosystem are of particular interest. The present study is a complement to a pot experiment that investigated the potential of different waste products for use as fertilizers and how they affect the microbial community. In the pot experiment, the clearest treatment change in microorganism community function was found in the fully fertilized treatment used as a positive control. The question was whether this was indirect, i.e.

Investeringsstrategier : En studie om relativvärdering som investeringsstrategi

Bakgrund: Något som många privatpersoner upplever svårt, är att välja aktier att investera i bland de tusentals som finns noterade på  aktiemarknader runt om i världen. Enbart på Stockholmsbörsen i Sverige finns det enligt Nasdaq OMX (2010) 288 stycken noterade aktier att välja mellan på huvudlistorna. En investerare har idag även tillgång till mycket information om företagen vilket bidrar till att det blir svårt att sortera bort vad som är oviktigt. Då målet för många investerare är att slå index är det intressant att titta på investeringsstrategier som kan tänkas slå index på längre sikt.Syfte: Syftet med studien är att undersöka investeringsstrategier på Stockholmsbörsen baserade på nyckeltalen P/E-talet, P/S-talet, P/BV-talet och direktavkastning. Detta för att komma fram till om det är det möjligt att generera överavkastning genom att följa någon eller några av dessa och om det visar sig stämma, komma fram till vilket eller vilka nyckeltal som är att föredra.Metod: Studien bygger på en kvantitativ metod där fyra nyckeltal har undersökts.Resultat: Studiens resultat visar på att det är möjligt att generera överavkastning gentemot index genom att följa en investeringsstrategi baserad på de studerade nyckeltalen.

Kaninhållning för sällskapsbruk

The domesticated rabbit stems from the European Wild rabbit and researchers have found that they share most of the characteristics and behaviors of their wild ancestor. They form mating groups in which strong hierarchic orders are formed and they are known for their ability to dig warrens which serve as one of the most important resources for this species. Although research has been performed to increase the welfare of rabbits kept in laboratory settings little is known about the housing, behavior and welfare of the pet rabbit. Among the research that has been performed within the area results have shown that the animals are kept in small solitary cages and that although many rabbits are purchased mainly for the children many animals cannot be handled by children due to display of aggression. Another conclusion drawn is that the animals are kept in ways that differs greatly from their natural environment.

En jämförelse av beteende mellan vävande hästar och två icke vävande hästar under liknande förhållanden :

Today we keep our horses in a way that is easy for us humans but may not always be the most optimal way for the horse. Often the housing of the horse prevents the horse from performing behaviours that they have natural needs to perform. It is not unusual that animals that can not adapt to their environment develop abnormal behaviours. Many of our stabled horses therefore develop some kind of stereotypic behaviour. This study was made in purpose of comparing the behaviour of a weaving horse to two non-weaving horses under similar conditions, where one of the horses was stabled next to the weaving horse and the other horse was stabled further away in the same stable. Seven weaving horses were included in the study.

Returlogistik inom e-handeln - En fallstudie av fyra modeföretag i Sverige

E-handeln med mode karaktäriseras av hög returandel och ofta lågvärdiga varor med relativt kort livslängd. Det ställer stora krav på företag att effektivt hantera returer, både operativt men också strategiskt. Denna studie undersöker fyra modeföretag med försäljning online. Företagen har olika egenskaper vilket ger ett komparativt underlag till studien. Exempelvis har företagen olika affärsstrategier, olika antal försäljningskanaler och olika historia, som påverkat utformningen av deras respektive returhantering.

En undersökning av specialpedagogiska perspektiv inom ridterapi

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

Skattningar i gallringsskog med hjälp av flygburen laserskanning : beräkningar med massaslutenhet

This master?s thesis is a remote sensing study of an area-based method used to detect forest in need of thinning by use of laser data and field samples. Only pine-dominated forest has been included in the study and height limits were set to match empirical restrictions. The study area was in the municipality of Älvsbyn (Latitude 65° 40´ N, Longitude 21° 00´ E), in northern Sweden.The Swedish authority Lantmäteriet is currently laser scanning most parts of Sweden, providing new opportunities and applications. The primary aim of the national laser scanning is to create a new elevation model, useful in consequence analysis of climate changes.

Internationell diversifiering i portföljinvesteringar av institutionella investerare.Internationell jämförelse med fokus i Japan

Background: The global capital markets have enlarged investment opportunities and thus also the sources of funds for companies which increasingly face global markets for their services and products. Huge capital movements show that investors are constantly searching ways to minimise risk and maximise returns. In the light of the substantial growth of assets in institutional funds, an important question for international finance is the degree to which institutional investors have diversified their portfolios internationally. Purpose: The purpose of this study is to examine the international diversification of portfolio investments of institutional investors in Japan, the US and the UK and deepen into international diversification in portfolios of Japanese institutional investors. Demarcations: Institutional investors can use their power directly in companies or indirectly through capital markets.
