Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

The purpose of this paper is to present and analyze the yearly expenses for Swedish rental apartments during the period 1999 to 2007. At the end, it will give the reader a general picture of how the cost-level has fluctuated depending on the production year when the apartment building was finished, and where the same building is located. This paper has the following questions as a starting point:- Can there be an identification of regions depending on where people tend to favor renting an apartment?- How are those regions distributed? That is, where are the cost-levels of the yearly rental expenses highest and where are the levels lowest?Nine statistical surveys from the Swedish government agency Statistics Sweden (Statistiska Centralbyrån) have been used as primary sources for this paper. These surveys deal with price pictures of housing in general, but for this paper the only information that has been used is the one about rental apartments.

Sitka spruce (Picea sitchensis) is a tree species that have its natural distribution along the West Coast of North America, from Alaska in the north to northern California in the south. Sitka spruce is a typical coastal tree species that can reach heights up to 85 meters and occurs in single pure as well as in mixed stands. The main purposes of this study were to describe the Sitka spruce growing characteristics and the volume production in comparison to spruce (Picea abies). The possibility to predict future volume production by using prognosis tools designed to be used on spruce were also studied. The material that has been used in this study are permanent sitka trials established by the Faculty of Forestry fixed Sitka trials and also material gathered in this study. A literature study was also carried out in order to determine the Sitka spruce growing characteristics. Sitka spruce has a high adaptation and a high volume production on a broad scale of soil types. The tree species is a pioneer species that has a fast early growth and in combination with sharp needles it is less susceptible to animal browsing than spruce. The factor that is the single most limiting factor for where the Sitka spruce can be planted is frost. This factor can be limited by using plant material with a well-suited provenance. According to the literature, the Sitka spruce has an average total volume production that is between 20-40% higher than spruce.

This report has a dual focus. The first goal was to increase the knowledge of how the use of electricity in a residential building is distributed. Electricity in residential buildings is used for lighting in common areas, elevators, pumps and many other appliances. The electricity used for these different parts is to a great extent unknown. A few studies have been carried out and the result of these is referred to in this report.By means of measurements and approximations the use of electricity for various appliances became known.

In an attempt to prevent ground damage and to reduce harvesting costs, StoraEnso's districts Värmbodal and Fryken, selected a number of final felling areas where the base roads have been marked by planners in the districts. The parties involved in the experiment are mainly planners, harvester operators and forwarder operators. The purpose of this paper is to determine the findings of this trial and to find cost savings or lost revenue. This has been done with a sample of interviews from the involved parties who logged the chosen felling areas. Literature about the interview process has been used to facilitate data collection, interpretation and analysis of the material. If we look at profitability based on assumed income and expenditure, revenue per MWh would be 63 SEK.

Most people have been forced to throw away a pot-plant after its death. There are many reasons to the death of a plant, but mainly it?s because its owner forgets it, and therefore fails to water it. The purpose of this project is therefore to develop a product which can prevent this from happening, while the product has to have a low manufacturing cost to be able to compete whit other, similar, products on the market. During the project, a benchmarking has been done to give a clear picture of what the product has to compete with. The directives there are for CE-marking, and which of these who concerns the product has also been looked up.

Detta examensarbete är utfört på Helsingborgs Dagblad AB i Helsingborg. Examensarbetet omfattar en analys ur kvalitetssynpunkt av HD:s material-, energi- och transportflöden, dess påverkan på miljön, kopplingen mellan HD:s tre kärnvärden och vikten av ett strukturerat miljöarbete samt ett antal förslag på fortsatt arbete. HD:s materialflöden består främst av material för tryckningen men även en hel del elektroniska apparater. Ett stort antal datorer och annan kontors-utrustning står på dygnet runt, året runt vilket orsakar onödigt stor energiförbrukning. HD:s verksamhet är beroende av transporter, både av material och personer.

A large number of system development projects are allowed to proceed for too long, and leads to undesirable project outcomes. Research shows that more than half of the authorities involved reported that at least one of their projects have exceeded their budget, and that a third of all the projects had exceeded the budget. This problem led to the following research question: ?Which factors can explain projects continued escalation within public authorities?? To answer the question, a qualitative case study of the Swedish police?s implementation of PUST, a sort of case management system was conducted. The project received considerable media attention and a large amount of criticism was directed towards the project, partly because the project exceeded the timeframe and budget set at the start.

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

Through the growing use and availability of information technology the dependency of Internet is today increasing. Internet makes ways for a more mobile business communication that cost less. One of the latest applications of Internet technology are intranet and extranet. I have asked myself the question how intranet and extranet can affect companies efficiency and competitive advantage. In order to answer this question I performed a case study at Ericsson and ABB.

The aim of the thesis was to investigate energy consumption and carbon dioxide emissions from an advertisement broadcasted on the radio or the television or distributed through press. The object was to calculate the amount of carbon dioxide emissions per individual receiver of an advertisement in Sweden. There was no room for a deeper investigation into editorial work within the framework of the thesis. Consequently, main focus of the radio and television study was on broadcasting itself and the components involved. Focus for the press study was on paper production, printing and distribution. Production and discarding of media equipment was not taken into account.

Denna uppsats bygger på ett projekt med syfte att öka företags konkurrenskraft genom att formera grupper, där kontaktytorna mellan företag sinsemellan samt mellan företag och universitet skall utökas och därmed ge utbyte av viktiga erfarenheter. Uppsatsen beskriver fem småföretag som producerar livsmedel och har arbetat i en innovationscirkel med ovanstående syfte. Dessa fem företag, Nordupplandsgruppen, har identifierat ett gemensamt intresse under dessa innovationscirkelträffar, nämligen att genom samverkan lösa det avsättningsproblem som finns hos företagen. Syftet med uppsatsen är att utreda företagens möjligheter att lösa detta problem genom att samverka inom marknadsföring och försäljning. Företagens problem med att få avsättning för sina produkter med bättre lönsamhet har visat sig vara en följd av resurskrävande distribution. Företagen har höga externa transaktionskostnader, det vill säga resurskrävande transaktioner för att sköta kundkontakter, söka nya kunder, presentera produkter, planera transporter och göra uppföljningar i butiker.

Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.

As to now, no study has been made of the mica tempered pottery found along side the asbestos tempered pottery in Norrland during the Bronze Age and Early Iron Age. Its occurrence has previously only briefly been noted in a few published works and the dating and geographical distribution of mica tempered pottery in the north of Sweden has to a large extent been unknown. This paper aims to compile the available information about this type of pottery and the locations where it has been discovered in order to date and explain the occurrence of mica tempered pottery in Norrland. It's also suggested that the occurrence of mica tempered pottery is connected to the spread of the early metalwork from the east to areas that today makes up the north of Norrland..

Micro-power wind energy convertors have recently increased in popularity. The reasons for this are among other things the increasing cost of electric energy and enviromental concern.In this thesis the connection of these micro-power wind energy convertors to the utility network is discussed. Electric standards for the connection of small production units is presented. Finally some calculations and measurements of electric quality are also presented. The utility network used in the calculations is part of Halmstad Energi och Miljö network..
