Utvärdering av den biologiska reningen av processavloppsvattnet vid GE Healthcare i Uppsala

GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter.

Vattenkemin i Fyrisån under snösmältningen

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.

Packning av lastbilsbyggsatser på Scania

Government regulations and customs duties restrict the import of trucks to some of the markets to which Scania tries to sell their trucks. The distribution problem due to these regulations is solved by the foreign assembly department, KD, at Scania. This means that competence is needed and costs are added not related to Scania's core operations.The aim of this master thesis has been to analyse and to evaluate alternative ways of managing the packing operations considering cost, quality and work organisation. To study and examine the work methods and operations of today and also to present methods measuring the operations effectiveness and productivity.We have used the system approach to maintain totality and to understand the component's relation to this totality. Field studies combined with studies of relevant literature and studies of other companies operations have given us the knowledge and the understanding of the packing operations needed.

Effekten av mjölkkors rang på ?antistresshormonet? oxytocin, mjölkavkastning, mjölkflöden och besökstider i mjölkningsenheten i ett automatiskt mjölkningssystem :

The study was carried out at the Kungsängen Research Centre, Department of Animal Nutrition and Management, Swedish University of Agriculture Sciences, Uppsala. The technical development in dairy production has resulted in a housing system where feeding and milking is done automatically without human contact, a so called automatic milking system. The motives for utilising an automatic milking system, is to increase the animal welfare and to decrease the need for manual labour. However, the system does involve a change for the animals, among the effects is the deprival or the diminishment of a chance for synchronous behaviour and the animals have to agree among themselves in which order they use the feeding stations and the milking unit itself. How and if this affects the animals well-being and production is yet to be solved. A possible way to form an opinion on this, is to study the animals ranking order along with hormone profiles and production. The purpose of this work was to study the effect of low- vs.

Dynamisk massbalansmodellering av fosfor i Östersjön

During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.

Utredning av alternativa distributionssystem för Holmen Paper

Holmen Paper is one of Sweden?s leading manufacturer of paper, with two Swedish production facilities located in Norrköping and Hallstavik. The European continent constitutes the company?s largest customer base which makes the company?s distribution system an integral part of the business. Historically, much of the produced paper has been transported by vessels, as vessels allow large volumes of goods and deliveries to markets which are difficult to reach with other modes of transportation.

Självförvållad sinnesförvirring : Konsekvenser av att fingera tillräknelighet istället för uppsåt vid gärningar som begåtts under självförvållad sinnesförvirring

This thesis, in the field of healthcare logistics, has been carried out at Hjärt- och Medicincentrum (HMC) at the University Hospital in Linköping during the fall and spring of 2012/2013. The thesis is done by two students at Linköping University at master?s level within the framework of Industrial Engineering and Management.As Sweden's county councils should not make a profit or loss, it is important that the councils are aware of how much care processes cost. Kardiologiska kliniken at HMC in Östergötland?s county council is one of the clinics that are profitable.

En Djupdykning i Kommunikationsstrategi : om konsten att locka folk till svenska dykvatten

Purpose/Aim: To create a communication strategy for PADI Nordic with the intention of getting Swedish divers, who have been certified abroad, to Swedish dive centers.Material/Method: The study is based on a number of personal interviews conducted with a) divers who are active in Sweden, b) divers who are not active in Sweden and c) representatives from PADI and PADI affiliated dive centers.Main results: The main reason that people who have been certified abroad do not dive in Sweden is that they regard it as being too complicated, too cold, too expensive and with nothing interesting to see. These might partly be misconceptions that can be corrected through a communication strategic effort. The best way to change this perception is by two different forms of communication. One will go from PADI Nordic straight to the divers through an email. This will have the purpose of getting their attention, making diving sound interesting and raise their awareness in preparation for the other part of the process.

VÄRDERING OCH REDOVISNING AV FÖRVALTNINGSFASTIGHETER I KONJUNKTURNEDGÅNG

In the year of 2005 the international standard IAS 40 came in to use in Sweden, this lead to an opportunity for the corporations to choose either to evaluate their investment properties according to the historical cost accounting principal. The model contains the obtaining price with reduction for the planned writing off. The alternative that IAS40 offers is the fairvalue principal, which evaluate the investment properties by consideration of the income versus outcome and surrounding factors for every accounting periodSince the fairvalue is buildt on numbers the corporations them self choose what to publish and for how long the value depreciation should be lasting before it should be taken up as an unrealized value change in the reporting material. This means that there is a big chance that the evaluation can be distortedSince we just recently have had strong cyclical variation and are on our way from an excess boom into a weak economic climate, this will be the first study performed about fair value in a weak economic climate since the adoption of IAS40.The purpose of the essay is to find out how well the booked value of investment properties owned by corporations listed on the Swedish stock market accord with the fairvalue that the market and the Swedish property index indicates on. To be able to test this connection we gathered information from the corporation?s annual reports which we compiled to see how the market comprehends.

Miljöcertifierade byggnader Värde för investeraren

This bachelor thesis describes why investors should invest in environmentally certified buildings instead of non certified buildings. The report provides an overview of possible factors influencing an investor in the investment process of an environmentally certified building. The report explains why building companies find incentive to build green buildings and how a cash flow method can be adapted so it can be used in the valuation process of an environmentally certified building. Environmentally certified buildings are used as a strategy to reduce emissions that threaten the environment as well as a strategy to obtain market shares for the building companies. This report focuses on the economic advantages of an environmentally certified building.The construction- and real estate industry stands for approximately 40 percent of the energy consumption in the world.

Kommunikation, uppföljning och tidsplanering inom detaljprojekteringen : Hur projekteringsprocessen kan effektiviseras med små medel

Producing a building is a long and complex process. It consists of several parts, from the feasibility study and design stage onto the construction and finally the management of the building. The design process is a critical part of the process where construction plans are made. The quality of the plans affect the production phase in great extent and faulty plans can pose a risk for extra costs for all parts in the process. The cost of producing dwellings has increased the last years and the detail design process is one of many phases where improvements can mean cost savings within the whole building process.This report aims to point at parts within the detail design process which could be more efficient, regarding communication, follow-up and time planning, and to give suggestions for improvements.

Passage efficiency and migration behavior for adult Atlantic salmon at a Half-Ice Harbor fish ladder

Due to exploitation of the world?s rivers, the upstream migration of anadromous species is frequently delayed or even prevented. To mitigate these problems and allow fish to migrate past obstacles, structures such as fish ladders have been developed. However, recent studies show that many of the present fish passage facilities are deficient. Monitoring and evaluation of passage facilities is therefore crucial to enable necessary adjustments.

Reala optioner : ett strategiskt verktyg

Background: Businesses are traditionally valued with the so called Discounted Cash Flow-model. When valuing newly-started businesses, surrounded by high uncertainty, and whose capital mostly consists of unrealized business opportunities, the Discounted Cash Flow-model needs to be complemented if the total value of the business is to be captured. A valuation with the help of real options is capable of valuing these unrealized opportunities, which often exist in newly-started businesses. The unrealized opportunities are to be found in the business plan of the business, why this needs to be valued to capture the total value of a newly-started business. Purpose: To demonstrate what the use of real options can result in when valuing businesses.

Uppvärmd konstgräsplan : Beräkning av utnyttjningstid för en uppvärmd konstgräplan med alternativa rörplaceringar

For Skattkärr IF a turf field with warming has been projected to increase field?s utilization hours and to have a longer period for athletes to perform their activities outdoors. The technique chosen to heat the plan is a type of a geothermal heating system without a heat pump. The brine, which is water with 30% ethanol, collects heat from the borehole and discharges it to a coil in the field. There is at position 11 boreholes but it is planned to increase the number to 31, which is the design for the facility.

Ersättningsnivåer - En studie av fast och rörlig lön till verkställande direktörer i svenska börsnoterade företag åren 2001 till 2005

Background and problem: Whether or not the pay to executives is fair is widely debated. During the last years especially the variable pay has been in the spotlight. But at what levels are the compensations really at? Media?s focus is mainly on the absolute highest compensations which may result in a skew view on pay-for-performance incentives.Purpose: The purpose of this thesis is to establish the levels of compensation to executives in a wide range of randomly selected companies listed on the Stockholm stock exchange during the years 2001 to 2005. Furthermore, the impact of a set of firm specific variables on compensation levels will be analyzed with basis in several hypothesis.Delimitations: The variable pay considered in this thesis will only be variable cash bonuses.
