Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.

This two years master's thesis examines the experience of children who read to a dog. The theoretical framework is inspired by sociocultural theory developed by Roger Säljö and the concept carnival inspired by Mikhail Bakhtin. The sociocultural theory has been chosen because it emphasizes the role of practice, instruments and communication in learning and the concept carnival has been chosen to analyze the experience of reading to a dog.The method used is qualitative interview and observation. A total of eight interviews and two observations when children read to a dog have been collected. One interview is with a teacher and seven interviews are with the children (six children participated and one child was interviewed twice).

The main objective in this study is to examine the pupil?s possibility to affect the upper secondary schools in Stockholm, Sweden. I was once active in the pupil?s council and experienced some hardships, feeling a great dissatisfaction among teachers and principals against pupil?s suggestions and chances to affect their school environment. Thus I wanted to do a contemporary study of where schools in Stockholm stand today within this issue.

AimThe aim of this essay is by using a motor skill track to see if there exists any remarkable difference in the motor skill profiles between pupils from our montessori school and the mean score in the "Nytidstest". The questions at issue we had were: How is the motor skill profile on pupils in year 2 and 3 practicing montessori pedagogy? Is the motor skill profile superior or inferior to the mean score in the "Nytidstest"? What factors, if any, concerning the montessori pedagogy affects the results of the test?MethodWe used a motor skill track consisting of 8 stations sellected from the "Nytidstest" adapted for year 3 (the original test consists of 16 stations). Pupils from year 2 and 3 in our chosen montessori school were tested in groups of 4-5 persons each. We made the tests on two occasions each lasting for 100 minutes at the time.

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

The purpose of this essay is to examine for the age discrimination towards older people in the working life. The essay practice EU-law and national law to examine the age discrimination. It also looks for the limits towards age discrimination. A presentation of the rules will make it easier to see how employers are possible to get around the ban against age discrimination. This essay also illustrates how age discrimination emerges in recruitment processes and then how to discourage age discrimination.

The results show that use of locally installed renewable energy sources can reduce the total climate impact when life cycle perspective is applied.

Masters thesis in Business Economics IV, VT 2012Linneuniversity in Kalmar Authors: Johanna Susaeg and David JohanssonTutor: Petter BoyeExaminer: Karin JonnergårdTitle: Fair value - How real is it? Background and research discussion: The concept of fair value is today connected with great uncertainty, which may be a result of the various guidelines developed during recent years. Hence, auditors have an important role in situations where they have to make projections concerning fair value and also do inspections of the management´s own assumptions.     The critique that has been shown regarding fair value is that it can be difficult to estimate, especially when there is no active market to proceed from. This problem has been confirmed through that the management often uses the estimations subjectivity to deliberately show higher or lower values in the accounts. Purpose: The purpose of this essay is to study and describe auditors, appraisers and real estate companys interest and procedure in valuation of real estates.  We also going to describe theirs view on fair value of real estates plus analyze and explain the actor?s roles in the valueprocess and how their particular interests can affect the final valuation in different situations. Methodology: The study is characterized by a qualitative method containing a pilot interview and several personal interviews with auditors, estimators, and real estate companies.

Vid kemisk massatillverkning finns behov av mättekniker som möjliggör ytterligare optimering av processen. Möjligheten att analysera svartlut med hjälp av aktiv akustisk spektrometri utreddes genom att ett online instrument konstruerdes och installerdes på ett pappersbruk. Analyser med multivariata metoder utfördes på resultaten. På grund av yttre omständigheter försenades arbetet, och ett tillräckligt dataunderlag för en definitiv slutsats erhölls ej. En rad vidare arbeten föreslås..

This report is the result of an investigation of the possibility to use RFID-technology in a producing company. The investigation is focused on a flow between the company?s producing subsidiary company in Lithuania and its main facility in Sweden.RFID is the abbreviation for radiofrequency identification. The RFID-technology forms the base of a system with wireless information transmission between an object to which a transponder, also called tag, has been attached and a reader. The information is transmitted by radio waves and the system is equipped with software that can digitalise the radio waves.

The culture center studied has gone from being organized by enthusiasts and ideals, to being institutionalized with a educational association responsible for the management. The questions discussed are ? how this change affects the active people in the house and what consequences these changes make for the institution of the house and for the regular management..

The importance of chemical use is enormous for areas such as agriculture, industry and medicine and hence a prerequisite for our modern society. In order to protect humans and the environment from the negative effects of chemical use, chemical regulations have been used at a relatively early stage in our history. The purpose of REACH, the new chemical regulation of the European Union, is to generate new knowledge of chemicals within the European market and to increase the responsibilities of the enterprises when it comes to risk management. Whether the enterprises will implement the regulations or not will be of vital importance for the realization of the law?s intentions.The purpose of this study was to identify possibilities and problems that can occur when a downstream-user SME is about to implement REACH.

In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.

Intro: 80 percent of the Swedish population own shares. This makes Sweden the leading country in private investment in securities. It can be difficult for the private investor to know where, when and which security to invest in. The strategies are as ambivalent as the stock markets fluctuations. If the investor prefers to refrain from investing money himself, there are brokers who carry out these types of services.
