Landfill leachate contains a variety of contaminants and is created when rainwater percolates the landfill. For landfill management the leachate is the main issue that can cause problems to the environment. At the landfill of Fläskebo, Renova AB treats the leachate in a local treatment plant. The treatment consists of a chemical treatment step with chemical precipitation, flocculation, sedimentation and filtration, and a final step with a carbon and peat filter. Renova has to ensure that the condition of the leachate reaches the regulation set for the landfill before it is released to the recipient.

Background: What is a share and what determines the value of a company? This is a constant issue that many in the financial world are facing. Many argue that there has been some decoupling between stock valuation and how the company in question is developing operationally after the financial crisis that the world faced during 2008-2009.Problem: It is important to distinguish between the company and the share. A company that is good and well maintained may not be worth buying only because of it. The share is judged by other elements also.

This master thesis work was done at Saab Underwater Systems AB, a company at the cutting edge of underwater technology. Here torpedoes and other underwater vehicles are developed and manufactured. The major customers are navies of different countries, mostly the Swedish navy. The aim of this master thesis is to develop, construct and evaluate an automatic Trim System for Unmanned Underwater Vehicles. The task of the system is to change the position of the centre of mass and the vehicle?s total mass or volume.

When driving hard and cornering on a circuit good control of a car?s roll is desired, so the car reaches steady state quickly but yet in a controlled fashion. This control is mainly given by the combination of the cars springs, shock absorbers and anti-roll bars.The aim of this report is to investigate, analyze and measure a Porsche Boxster?s turn in behaviour and roll dynamics as well as with the aid of simulation results give suggestions for improvement of the previous mentioned combination.Two different simulations were made, one based on a simpler model that was based on an evolved version of the bicycle model in Matlab and one was more advanced model in the simulation software rFactor. Measurements of the real car was made using a GPS-based measurement system.

Title: Valuing Real Estate FCFE and interest coverage under macroeconomic uncertainty with scenario analysisAuthors: Marcus Ewerstrand, Jakob MattssonAdvisor: Gert SandahlBackground and problem: After the collapse in the Swedish economy in the beginning of the 1990-ties, the company Secerum was launched. Securums objective was to handle unsecured credits from Nordbanken by transferring a large portfolio of properties and to setup a number of companies who would be in charge for the prospects of these assets. One company that was established during this remarkable period was Castellum, in the year of 1994. After a successful process of raising capital to its development of corporate strategies and formation of several affiliated companies which operates locally, Castellum was publish on the Stockholm stock exchange 1997/1998. Now, thirteen years later after its establishment, the credit crunch in the US.

I dagens samhälle blir det allt mer intressant att spara energi, dels med tanke på miljön och dels föratt minska på utgifterna. Denna energi ska sparas på ett sådant sätt att effekten för användarna blirså liten som möjligt.I denna rapport beskrivs hur ett reglersystem kan byggas för att minska energiförbrukningen hosväxthus genom att reglera belysningen på ett effektivt sätt. Systemet är helt automatiskt vilket göratt användarna inte behöver tänka på styrningen av lamporna alls när väl systemet är uppsatt ochkonfigurerat.För att styra lamporna på ett bra sätt mäts det inkommande ljuset med en PAR-sensor. Lampornatänds och släcks därefter beroende på ljusmängden och även på hur varmt, eller kallt, det är iväxthusen.Styrningen av belysningen sker med en mikrokontroller från Microchip, en PIC18F4620 som ärprogrammerad i C18. Kringkomponenter som portexpasioner, klocka och reläer användes också föratt bygga ett bra reglersystem.Resultatet är att det är möjligt att bygga ett reglersystem med begränsad budget som styr lampornapå ett effektivt sätt.

Quality Control is a term often used within production and is referring to managing processes so they produce capable products. Within Quality Control, process capability index is a common measure to oversee processes. Safety Region Plots were introduced to do this graphically. In Albing & Vännman (2010) the concept of Safety Region Plots is expanded to incorporate an elliptical shape. The method of Elliptical Safety Region Plots assumes a normally distributed data.

Capital structure is without doubt one of the most frequently studied and controversial areas of modern financial theory, and will certainly continue to receive considerable attention from researchers worldwide. There is still no universal explanation of how an optimal capital structure would be designed for maximum appreciation, despite the development of several theories focusing on the subject. Equity and debt are the two main financing options that in combination explain the business's capital structure. The results of several research studies conducted in the subject has many times pointed out that there are specific factors that are directly related to the company's capital structure, and that there are clear sectoral differences in corporate debt. A study of the capital structure is considered important and interesting to implement due to the reasons above and the purpose of this study is to analyze and try to explain the similarities and differences between different industries in terms of how growth, profitability and size affect the debt level.

The return of large predators to regions where they were previously extirpated has created a need for knowledge about their effect on prey species, not only their lethal but also their behavioural or risk effects. In this study the behavioural risk effects of brown bear (Ursus arctos) were tested on fallow deer (Dama dama), roe deer (Capreolus capreolus), red deer (Cervus elaphus), moose (Alces alces) and wild boar (Sus scrofa). This was done by using patches of fur to simulate the presence of the novel predator (brown bear), a novel nonpredator (reindeer (Rangifer tarandus) and no fur as control. These three treatments were then compared. The response variables measured were increased vigilance, decreased feeding time and change in patch use.

Title: The qualified audit report ? a study of Board of Director, Private Corporation and auditor?s impact.                      Seminar date: 31th of May, 2011Authors: Annika Jonasson & Emma SwanbergSupervisor: Andreas Jansson                Education: the Business Administration and Economics Programme      Course: Thesis, the Business, Administration and Economics Programme, 30 creditsKeywords: Qualified audit report, accounting, audit, auditor, board of directors private corporation, stakeholderBackground: It is important for the company's stakeholders to receive information what affects qualified audit report. The information is also important for the company?s management or owner in order to prevent qualified audit report. Board of directors (the ability to control the owners or management and provide critical resources), the management or owners (incentives to manipulate the annual report) and auditors (the ability to discover and report false financial statements) may have an impact why Swedish private corporations receiving qualified audit reports.  Purpose: The overall purpose is to examine why Swedish Private Corporation receives qualified audit reports.Methodology: In order to fulfill the purpose of our thesis a deductive approach is used.

During the last decades the fertility of dairy cows has declined in the same rate as the milk yield has increased. This is a result of the negative genetic correlation between milk yield and fertility, failure to show estrous signs and metabolic problems in the cow. The purpose of this review was to investigate the function of metabolites and hormones as markers for disturbances in fertility, health and production in the dairy cow. There are several metabolites that are suggested to indicate the cow?s energy balance.

På senare tid har en kritisk diskussion växt fram kring användandet av budget som styrmedel. Budgeten anses vara tidskonsumerande, resurskrävande och den anses även inte tillhandahålla relevant information, vilket har medfört att det finns företag som avskaffat budgeten som styrmedel. Men hur styrs företag utan budget och är det möjligt att styra ett företag utan budget? Det finns forskare som anser att företag som styrs utan budget får problem med planering, samordning samt styrning av aktiviteter då de saknar ett ramverk. Ahlsell AB är företag som har styrt sin verksamhet utan budget i 17 år.

Communication is a part of everyday life. The more sensitive information we handle, the more interesting the question around security of your information becomes. There are two ways of handling security around the information you want to communicate, either you control the means by which you are communicating. Or you control the way you communicate, making you able to use existing communication channels. Existing methods within cryptography enables two parties to communicate information securely.

The purpose of this study is to analyze how special education is done in relation to what is considered "normal". The aim is to discuss how the normalization discourse appears in a pre-school for all and, by extension, how the need of special education is articulated in relation to the normalization discourse. This study also intends to discuss how the perception of what is normal affects special education in pre-schools. The study draws upon previous research within the special education area through which we make our position. Since there is only a few studies in this chosen field which are based on empirical data, our study indicates the importance of more research in this field.

SummaryThe purpose of this thesis is to examine what effect the IFRS 2 has on earnings, equity, financial strength and return on equity for listed Swedish companies with active stock option plans. The purpose is further to investigate the companies? attitudes towards IFRS 2 and to find out if companies tend to deviate from stock option plans due to the changed accounting rules. We also want to examine the view of IFRS 2 from an auditor?s perspective.We have used a deductive approach and a mix of quantitative and qualitative research methods with a view to get a completely clear picture within the field of study.
