Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.

During the early Middle Ages beech forests (Fagus sylvatica L.) spread out over large parts of southern Sweden. They had a crucial role in human survival for hundreds of years. For various reasons, the beech forest area has decreased since the 1600s. Spruce planted on former beech forest land was the primary reason for the decline during the second half of the 1900s, which made many worried about the future of the beech forests and led to a beech forest act in 1974. This study describes the background to the beech forest act based on parliamentary official documents.

Climate change is one of the most difficult problems that humans have to deal with. Today, the evidence of human effects on the climate change and the rise of temperature on earth are strong. It is extremely important that all countries get together and cooperate in order to be able to solve the problem with climate change. One step in the work on climate changes is the Convention on Climate Change, which was agreed on in 1992. The Convention on Climate Change resulted in the Kyoto Protocol in 1997. The Kyoto Protocol is an agreement between a number of industrialized countries to limit or reduce the green gas emissions.

Our essay is about alcohol information given to youths in Helsingborg. It is a research to find out how the message is communicated and how it is presented. The purpose of our study is to find out, why inform about alcohol and if it is taken in a preventive aim. To investigate weather there is any talermade information in the community for youths between 12-18 years old. We also want to know if the given information is destined for a special group/groups or is it for young people in general? Our intention is to find out the meaning of prevently information about alcohol and if it is possible to reach a change in attitudes and behaviour.We use a qualitative method and have interviewed twelve persons with different occupations within medical service, local authorities, public and private schools and voluntary organizations..

The purpose of my study is to find out which way the extended school staff has their knowledge about conflicts, what they think is the cause of a conflict and how they handle conflicts.To answer these questions, I have chosen to do interviews with an available group. I interviewed six persons of different gender, age, nationality and they have been working from three to twenty years at afterschool care.I have analyzed my empirical material using Szklarkis four causes of a conflict and Malténs strategies for conflict management.My conclusion is that the after-school staff's knowledge is mostly based on experience, partly through work with children group in afterschool care and as a youth leader in the voluntary sector. The strategy almost always used for the after-school staff were the collusion strategy.

This thesis consists of four case studies. The objective is to find out how to get a well functioning cow traffic in an automatic milking system. Different technical and building solutions are analysed and some adjustments are proposed for the DeLaval herd management software. Case study 1: Lactation chart comparison from traditional cow traffic and Feed First? cow traffic Case study 2: Farm A - a study of the precedence passage and the cow traffic Case study 3: Farm B ? an overview of the farm and their way of working Case study 4: Key factors ? how can we judge how well a VMS farm is working? Case study 1: Lactation chart comparison from traditional cow traffic and Feed First? cow traffic In this survey data is analysed from before and after rebuilding to Feed First? cow traffic. Lactation graphs are compared between traditional cow traffic and Feed First? cow traffic.

På senare år har en ny trend inom miljöarbetet uppstått. Istället för att bara vara miljövänliga tar vissa företag och organisationer det hela ett steg längre och klimatkompenserar för de utsläpp de har. Företag som klimatkompenserar hävdar att de gör allt de kan för att först och främst minska de direkta utsläpp som de förorsakar. Som en sista åtgärd, för att ytterligare minska företagets påverkan på miljön, kompenserar företagen för sina utsläpp genom att delta i något miljöfrämjande projekt. De bakomliggande motiven till att klimatkompensera är främst ett starkt miljöengagemang inom företaget sedan tidigare.

Background: Enterprises often refer to their employees as ?Our most valuable assets? in annual reports and other written statements. In reality, employees are seen as an expense rather than an asset in annual reports and the voluntary disclosure is often insufficient. Human capital disclosure has been discussed through decades and the latest topic in voluntary disclosure is called integrated reporting. Knowledge firms should disclose more about their employees than industrial companies due to the fact that the employees are a considerably more important asset to these types of enterprises.Purpose: The purpose of this thesis is to study the disclosure of human capital, compare the disclosures between knowledge firms and industrial companies, and study the development of the human capital disclosures between the years 2003-2013.

In connection with Henriksdals wastewater treatment plant (WWTP) a smaller plant is situated called Sjöstadsverket where new methods for wastewater treatment are tested and evaluated in different process lines. On one of the lines experiments with enhanced biological phosphorous removal (EBPR), have been carried out to evaluate if it is a good alternative to traditional chemical phosphorus removal. This thesis evaluates the results from the experiments conducted during fall 2005.The incoming water from Hammarby Sjöstad consists of only household wastewater, which gives a wastewater with high concentrations of nutrients and organic carbon. This is partly positive, because one of the limiting factors for effective biological phosphorus removal is the lack of easily biodegradable organic carbon. The high concentrations of ammonium and phosphorus demand a high reduction to achieve the requirements of outgoing concentration.To optimize the process experiments with different recirculations and different aeration techniques have been made.

In many European countries there is an increasing concern about the occasionally high concentrations of nitrate and pesticides in drinking water. The advent of the EU Water Framework Directive particularly highlights this. The directive states that all large drinking water sources should be identified and protected from pollution before 2009 and that by 2015 all water bodies should reach a 'good status'. In Sweden about 60 percent of the drinking water sources have protection areas. This means that about 700 new water protection areas need to be designated before 2009. This will affect many farmers, restricting their farming practices. The purpose of this study was to investigate which methods are used in other countries concerning nitrate and pesticide pollution from agriculture. From this, the expectation was to generate ideas on what could be undertaken in Sweden when designating new protection areas.

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

Nitrogen deposition leads to environmental damage in areas where the nitrogen deposition is high. Southwest Sweden receives an annual nitrogen deposition of up to 20 kg N/ha. Nitrogen that is not assimilated by the vegetation is accumulated in the soil, which may lead to nitrogen saturation and an elevated risk of nitrogen leaching. Nitrogen leaching from forest areas in southern Sweden has proven to be higher than from agricultural areas, which have been thought to be the main contributors to elevated nitrogen levels in rivers and lakes. The amount of nitrogen that leaches depends on the fraction of the total nitrogen in the soil that consists of nitrate, since nitrate is easily transported through the soil.

Vad gäller reglerna om tidigare års underskott utgör koncernbidragsspärren en spärregel till den annars gällande huvudregeln att tidigare års förluster får kvittas mot framtida vinster. Koncernbidragsspärren inträder vid ägarförändringar och innebär förenklat att ett underskottsföretag är förhindrat att, under en period om fem år, kvitta kvarstående underskott mot koncernbidrag som underskottsföretaget mottar från företag som inte ingick i koncernen före ägarförändringen (nya företag). Underskott som uppkommer efter ägarförändringen får dock kvittas mot koncernbidrag från nya företag.Uppsatsen syftar till att analysera och granska reglerna om koncernbidragsspärren ur ett företagsperspektiv, vilket innebär att uppsatsen ser till reglernas bakomliggande syfte och till hur reglerna fungerar vid en praktisk tillämpning. Uppsatsen har ett särskilt fokus kring i vilken turordning koncernbidrag ska beaktas vid avräkning mot befintliga underskott när ett underskottsföretag mottar koncernbidrag både från gamla och nya företag i en koncern.

Background and problem: In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The emissions in the transportation sector have, in contrast to the total emissions, increased since 1990 and will continue to increase unless powerful control measures are implemented. The lorry centres have to use strategies to answer to these external threats which lead us to the two questions of this thesis: - What methods do the lorry centres use actively and which do they consider as the most important methods for fuel saving? - Are there any differences which methods small, medium and large centres considers as important? Purpose: The main purpose of this thesis is to examine which methods lorry centres use actively and which they consider as important for fuel saving.
