Continuously grazed grasslands have remarkably high plant species diversity. In Sweden this type of habitat has declined for the last two centuries. Changed land use has caused habitat fragmentation and loss of habitat quality. This has caused a great number of plant species to end up on the verge of extinction. To try to save this unique habitat and the species that are tied to it, lots of resources are laid on restoration of abandoned grasslands. In this study, plant species richness of continuously grazed, abandoned and restored grasslands were related to degree of overgrowth, time since overgrowth started and rate of overgrowth.

The purpose of this trial was to evaluate the possibility to use sampling of faeces, urine and plasma, and measurements of blood pressure as methods of discovering hypomagnesemia in horses, as well as the application handiness of these methods. The most commonly used method of checking the magnesium status of a horse is to analyze samples of serum or plasma. The trial was of a switch-back design, in which the horses were used as their own controls. The animal material was five Swedish warm blooded trotters between six to ten years old, and weighing between 485-620 kg. The trial consisted of three periods that were two months each.

I nära tio år har främst amerikanska placerare utnyttjat strategin carry trade för att skapa positiva avkastningar. Strategin innebär att lån tas på en marknad med låga räntor för att sedan placeras på en annan marknad med högre räntor. Det är främst de japanska och amerikanska räntemarknaderna som har använts.Syftet med uppsatsen är att utreda om det går att få en positiv avkastning vid carry trade-affärer. Vi kommer även att belysa vilka risker som uppstår vid dessa investeringar, samt undersöka vad som kan göras för att minimera de risker som uppstår. Genom att studera andra länder med betydande räntedifferenser vill vi även utreda om denna strategi går att tillämpa på andra ränte- och valutamarknader än Japan och USA.För att uppfylla syftet har en kvantitativ studie genomförts baserad på sekundärdata, där vi skapat olika fiktiva affärer över tre tidsperioder för att kunna räkna ut och jämföra avkastningar.

Escherichia (E) coli is one of the most common udder pathogens associated with acute clinical mastitis in Swedish dairy cows. The aim of this study is to review some of the existing literature on E coli mastitis from a Swedish perspective. The bacteria, its most important characteristics, and diagnostics under field conditions is covered, as well as what happens during infection, how E coli affects the cow and which consequences this have. Clinical symptoms associated with E coli mastitis are described and information on when these cases of mastitis usually occurs is given. Risk factors in the cow?s enviroment are described as well as the importance of the cow?s immune defence.

A study has been performed that investigates the variation of iron content in groundwater.The study was initiated by Midvatten AB, which noticed that the iron content in groundwater samples can vary greatly over small distances. The purpose of this study was to geochemically and geohydrologically determine the factors that influence the content of iron and manganese in groundwater from a selection of eskers in Dalarna, and determine how to best sample groundwater with the method used by Midvatten AB. An evaluation was made of how the vertical variation in soil material, water composition, pumping time and pipe material affects the content of iron in groundwater. Piper diagrams were used to study the relationship between the chemical composition of the groundwater and the content of iron and manganese in groundwater samples from the studied areas. The groundwater from the studied areas was then classified in the Piper diagrams, according to the content of the major ions.

The city of Uppsala and its surroundings are a very expansive area. A prerequisite for a sustainable development of the area is well-functioning supply of drinking water. In Uppsala municipality, the Uppsala esker and Vattholma esker are the groundwater storages for drinking water. Besides the eskers, other sources of qualitative groundwater in the Uppsala municipality are relatively poor and more than half of the area consists of ground conditions with a risk of saline groundwater. The neighbourhood of Vreta-Ytternäs is situated 10 km south of Uppsala, in the area with risk of saline groundwater but outside the municipal water supply.

Transfer of undertaking or business is a complex fact. It requires many aspects to be takeninto consideration. For there to be a transfer of undertaking or business, it has to be a stableeconomic entity that after transfer has retained its identity. The provisions regarding transferof undertaking or business is found in the transfer of undertaking or business directive,6 b § LAS and 28 § MBL.An employee?s employment is automatically transferred to the transferee.

At nuclear power plants, electrical valve actuators are important for ensuring that the reactor core is water covered and the pressure in the reactor tank and containment is limited. The electrical actuators are provided with overload protection in case of drawing higher current then the motors are rated for. When safety manoeuvres are needed, the overload protection must not trig and cause the valve to stop before completing the manoeuvre. Analyses have showed that the current settings of the overload protection may cause an illegitimate trig at the worst theoretically possible accident. A new method has been developed with conservative assumptions and applies overload protections for all electrical valve actuators at the three reactors in Forsmark..

Safety and risk management currently have a starting point based on the negative outcome of safety, thus the lack of safety. The starting point for the thesis is to find a way to measure the positive outcome of safety through ergonomic aspects regarding chemical plants that are covered of the Seveso II Directive.Through a literature study of safety and ergonomics fourteen key aspects of safety were found. Safety Performance Indicators (SPI's) are used to assess the fourteen identified proactive indicators of safety. An analysis in three steps - called risk status assessment - is design to give an SPI its value. A pilot study of the risk status assessment was performed at the ethanol producer Lantmännen Agroetanol in Norrköping, Sweden..

AbstractAuthors:Stefan Harrå and Magnus BjörkAdvisor: Markku PenttinenTitle: Accounting Consequences of the change in pension accounting Background to problem: When the revised IAS 19 comes into force January 1, 2013, it means that two of the three accounting principles for defined benefit pension plans are disappearing, including the corridor method. The corridor method has made it possible for companies to defer its actuarial gains and losses. Now that the corridor approach abolished then the unrecognized actuarial gains and losses immediately be covered by equity, which involves very large amounts of some companies. Why the amounts have grown so big is much because of the discount rate. The discount rate is a controversial parameter, and there is disagreement on how it should be fixed.Purpose: The purpose of this thesis is to examine the accounting implications this will have for the company applied the corridor method, and if there is some parameters in the actuarial assumption that is more important than others.Methodology: The thesis has mainly been based on a qualitative research through qualitative interviews with a small sample that is affected by this change.

A dilemma often met by entrepreneurs is whether or not to share information about their business ideas in order to increase the probability for success. The reason for sharing information is presumed to be an increased ability to develop the business idea, whereas the reason for maintaining secrecy would be to protect the idea from being stolen. Common as this dilemma is in practice, it is not very well covered in the entrepreneurial theories. The purpose of this thesis is to elaborate the theories in this subject by investigating an entrepreneurial case. The case shows that one possible solution to the dilemma is a situation-based information sharing.

In the thesis we have shown that it is possible with current technology, to buildneighborhoods that are largely self-sufficient. We have obtained some information aboutongoing work in the field of energy efficient buildings and active house which we have usedto develop a model. The feasibility study for Ranagård we have e.g been forced tofollow laws on groundwater covered, resulting in the construction of basements for singlefamilyhome is not possible. The model that we have built up overtime has been the central part of the work. The model illustrates very well what an activehouse neighborhood means and potential of such an area.
