The Effects of dietary biotin supplementation on hoof health in Swedish dairy cows - a controlled cohort field study. The aim of the present degree project was to investigate the effects of biotin supplementation on hoof health in dairy cows. The experiment was performed as a controlled cohort study in three commercial farms in western Sweden from January 2002 to October 2002. The cows were all housed in cubicle systems with transponder concentrate feeding systems. Within each farm the cows were allocated to either biotin or control treatment. The biotin groups received 20 mg of biotin per cow and day, starting 14 days before expected calving.

A wish for a higher standard of living has driven the rate of consumption in Sweden. Mainfocus in business is on a higher growth and profitability where some companies use a lowprice strategy to win competitive advantage. The positive consumption pattern spiral is oftendiscussed in media, while criticism is limited and often refers to the environment. In order toreduce our ecological footprint we should consume more sustainably. More and morecompanies implement CSR (Corporate Social Responsibility) in their business strategy tobecome more sustainable.

The objective of this work was to compare the environmentally gentle soil scarification technique Huminmix (with possibilities to do track-grinding/HMMspår, long-scraping/HMMlångfläck and mounding/HMMhög) with conventional disc trencher, concerning seedling establishment and growth of direct seeded and planted Scots pine seedlings. Inventories were made during June and July 2005, in 34 seeded and 6 planted stands from 2000 ? 2004 (1- 5 years old) of lichen- and myrtillus/vaccinum-type in Holmen Skog AB´s district Norsjö in Västerbotten. The Huminmix-technique had been used for HMMspår in the seeded stands and for HMMhög in the planted stands (HMMlångfläck has been used from the year 2006 for direct seeding). The studied stands had been seeded with the same amount of seeds according to stand data.

This thesis is a case study with a qualitative approach. The company examined is The Astonishing Tribe (TAT) making user interfaces for mobile phones. The company has had a growth of 1453% from 2002 until 2006. We have examined what are the key factors for keeping innovation while growing. The most significant factor not supporting innovation within the case company is the will to take calculated risks.

Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables? history. The study is limited to the Swedish market as it is based on the OMXS30-index which represents the 30 most exchanged stocks on Stockholms¬börsen, the Swedish stock exchange.

Purpose: The main purpose of the thesis is to examine the profitability of Momentum Strategies on the Nordic stock markets. This will provide insight and contribute to the debate on efficient markets. Finding profitable Momentum Strategies will provide strong evidence of inefficiency in the market. A secondary purpose is to examine factors which might cause or impact the profitability of the Momentum Strategy. We will look closely at the relationship between the profitability and factors such as risk (CAPM-beta), market capitalization, trading volume and seasonality.

Gastric and intestinal disorders are common and costly human health problems worldwide. Helicobacter pylori are a gram-negative, pathogen bacteria and the most common cause of duodenal and gastric ulcer in the stomach the intestinal mucosa. Prolonged infection and colonization can lead to chronic gastritis and stomach cancer. H. pylori are present in the gastric and intestinal mucosa of half of the world population and a relation between infection and low socioeconomic status has been shown.

AbstractBusiness, or business decisions always involves an endangerment from the company?s aspect, but when it comes to business with foreign countries the risk profile looks quite different from the profile the company has when its doing business inside the country. Therefore, it is extremely important for an export company or import company to carefully consider the risks that are enclosed with the deal, before he makes the decision to enter a deal. One of the most important risks a company have to considerate when doing business with foreign countries is the currency risk. A company is exposed to currency risk when either long-term or short-term changes in the exchange rate may affect the result of the company, competitive position and growth.

Since the release of Avatar in 2009, the 3D movie industry has experienced an apparent growth. Almost all blockbuster movies are being released in 3D at the cinema, but the 3D format has been met with mixed opinions by the consumers. Some argue that 3D is the future, while others believe that the 2D format is enough for an appreciated movie experience. Through a qualitative survey, twenty participants with 3DTV in their homes answered questions regarding their experience of 3D movies and what improvements they desire. We suggest that 3D film creates immersion, realism and effects that 2D films can´t handle.

In order to evaluate different afforestation methods for exposed heath lands a field experiment was established in Mosfell on southern Iceland in 1989. The trial comprised six different site preparation methods (control, herbicide application, tree shelters, patch scarification, TTS trenching and mounding). In total 960 container seedlings (1+0) and 960 Nisula roll transplants (2+1) of lodgepole pine were planted. Various planting positions (furrow, hinge, no site preparation (control) and on top of mounds) were tested within the site preparation treatments. This study involves renewed measurements and analyses of the trial.After 19 years the overall survival was 51,7 %.

The purpose of this thesis is to investigate if there is a risk that Sweden will go in to crises at the house market and in the bank sector. The Swedish house prices have in the last years growth very high and quickly and are now over the development in the beginning of 1990. The method I use to investigate this is a multiple regression model. I follow a regression that both OECD and the Swedish Riksbank use. The difference between my analyse and theirs is that we use different periods..

Healthy calves are the foundation in order to run a profitable diary production. Being healthy as calf results in a better start in life and good growth is expected to follow. Within dairy production it becomes more common to rear calves in groups and feed them by an automatic milk feeder. The milk feeder enables for the calves in greater extent to ingest milk or milk replacer several times per day and they are also able to perform natural behaviors in greater extent. Group rearing of calves puts higher demands on the animal keepers to localize individual calves in the group pen, showing signs of illness.

Trading financial securities at stock exchanges and other authorized market places is today a particularly important socioeconomic phenomenon in many industrialized countries. A well functioning securities market is crucial for the economic development in these countries. The modern trading with stocks and other financial securities is characterized by the fact that the majority of the transactions at the stock exchanges are carried out through various intermediaries. The ultimate counterparties that are involved in a securities transaction (the seller and the buyer) are often unknown to each other. The anonymity in the securities trading implies several interesting legal problems.

Chemical substances are spread diffusely and uncontrollably as a result of the increased consumption of goods. REVAQ is a certification system that works to reduce the flow of hazardous substances to Swedish treatment plants and to create a sustainable nutrient recycling. According to REVAQ, the yearly accumulating rate of metals should not exceed 0.2% in soil per year. Silver and bismuth are two metals that do not fulfill this requirement. The silver concentration in sludge decreased during the last decade, however the last few years, it has leveled off.

Beef production in Sweden has traditionally been about rearing of dairy calves to slaughter. With reduced number of dairy cows and accordingly less dairy calves for slaughter, there has been a need for new forms of beef production in Sweden. In Västerbotten there are good conditions for beef production with a high feeding level of roughage due to favourable climate. The aim of this thesis is to, through interviews with ten farmers with beef production in Västerbotten, study what and with how much they feed their animals and link the results to production level. The thesis begins with a literature review where the general feeding standards and feeding recommendations for beef cows and growing cattle are examined.
