Behandling av lakvatten med kemiska oxidationsmedel för att delvis bryta ned oönskade organiska förening : en studie utförd vid Hovgårdens avfallsanläggning i Uppsala
A renewed application for environmental permit for the Hovgården landfill in Uppsala shall be submitted before December 2004, therefore the municipality of Uppsala needs improved knowledge of the contents, mostly organic compounds in the leachate and they also want to find a method to minimize the emissions of these compounds. The purpose of this study was to find a practical and economical method based on chemical oxidation using oxidants. The oxidants investigated are Fenton's reagent, hydrogen peroxide, Oxypro, potassium permanganate and potassium persulfate.
The study was made on untreated leachate and leachate that has been treated in an aerated dam followed by sedimentation dams collected from the Hovgården landfill, and alson on sludge water from sludge storage cells.
The effects of the five oxidants have been established by analysing the UV absorbance at the wavelengths 253,7 nm and 260,0 nm at different pH values. The UV absorbance was used to indicate the amount of aromatic hydrocarbons in the water. Also analyses of iron and manganese were done after the experiments with potassium permanganate, hydrogen peroxide and Fenton's reagent.
Har du tid att vänta
In today's society, more and more people traveling with transports such as trains and buses. With this type of travel it often exists waiting at stations that in many cases perceives as negative. Previous research demonstrates that distraction can get people to experience the waiting as less negative. This paper aims to examine how waiting can be affected by distraction, and if it is possible to use a second type of waiting as a distraction. The authors have chosen to focus on travelers who are waiting.
Subventioner och hyresrätter? En bostadspolitisk studie
Since the early 1940s in Sweden, subsidies have been a recurring feature in housing politics.Throughout history, these have been used as a management measure to control theconstruction of housing and to promote the Swedish welfare state. The political parties aretoday disagreeing on how much responsibility the state should carry for citizens housing. Tosolve the conflict, the dwelling has to be defined. Is the dwelling to be considered a socialright, like education and healthcare or is the dwelling to be considered a product for the freemarket, driven by supply and demand?The positive population growth in Stockholm has lead to an increased demand for dwellings.The supply of dwellings has not been growing at the same rate, which has implied higherhousing prices and longer wait for rented apartments.
Kort speltid ? djupt intryck: spel som hyrfilm
SVENSKA:
Vårt kandidatarbete gick ut på att ta reda på om det var möjligt att utveckla
ett kort spel i hög teknisk kvalitet och ändå skapa ett djupt intryck på
spelaren. Under projektets gång utvecklade vi, med hjälp av UDK (Unreal
Development Kit), ett skräckspel i 3D till PC vid namn The Horror at MS Aurora.
För att erhålla den höga tekniska kvaliteten som vi var ute efter användes
metoder som räknas som standard för stora speltitlar på marknaden: Animationer
spelades in med Motion Capture och musiken skrevs med en full symfoniorkester i
åtanke. Innan produktionsfasen tog vid gick alla gruppmedlemmarna igenom en
research-fas, där var och en satte sig in i de områden som skulle komma att
vara aktuella under produktionen (d.v.s. hur UDK fungerar, musikteori och
orkestrationsteknik, hur man arbetar med Motion Capture-data o.s.v.).

It looks for links between business travel and work satisfaction among them. A short presentation of the patterns of business travel and relevant motivational and stress theories is given. Data for the paper is collected using a survey (78 participants) and interviews.
Saltvattenpåverkan i enskilda brunnar i kustnära områden : En undersökning av grundvattenförhållandena och riskerna för saltvattenpåverkan i S:t Annas skärgård, Östergötland
Coastal areas are popular for housing, both for permanent living and holiday houses. At the same time, thin sediments and small storage capacity in the bedrock makes the ground water resources limited. The limited ground water resources combined with too large withdrawals of ground water makes salt water intrusion a problem in many coastal areas. This study examine the risk of salt water intrusion in drinking water supplying wells on the island Södra Finnö in S:t Anna archipelago, Östergötland, Sweden. A calculation of the relation between ground water recharge and withdrawal is obtained to analyze the ground water balance in the area.

The purpose of this study was to investigate body awareness among men in military recruit training. BAQ was distributed to fifty recruits for military service in Boden.
Bacterial contamination of eggshells in conventional cages and litter floor systems for laying hens in Jordan
In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.
Planeringsfasen i fokus : En studie av fyra eventverksamheters projektplanering
Event is something that an increasing number of Swedish cities are investing in since it contributes to higher attractiveness of cities and generate economic revenues. New arenas are built around Sweden to meet the increasing demands to host such events. Event projects are carried out in Sweden and it is important that the planning phase is carried out thoroughly to get a successful project. This thesis aims to look more closely at selected organizations and how they plan their projects and whether it is possible to follow project plans in the event projects. Karlstad has many events that recur annually, including the Swedish Rally.

Shareholder value - The American way and the Swedish game to play? : En studie om ideologisk förändring i svensk bolagsstyrning
Shareholder value has its origin in the American corporate governance system and has been the subject of great debate over the last few decades. The proponents claim that it creates economic efficiency while the critics argue that maximization of shareholder value jeopardizes the long term survival of companies. However, the debate in Sweden already seems to have forgotten the question of how embedded the ideology really is and what´s leading its way. This study show that shareholder value has developed and been established in Swedish companies between 1995 and 2005. The study has found evidence that suggests that the development can primarily be linked to board networks and international exposure.
Starka kvinnor och männen i deras skugga : En maskulinitetsstudie i Cirkeln
This paper investigates the relationship between the two modernist writers Katherine Mansfield and Virginia Woolf. The two authors had a frail and complicated friendship that influenced their fiction and fictional characters more than the general public knows. My paper investigates how Woolf can have found her fictional story ideas direct from their friendship. With a comparative theory I?m finding and giving examples of how their friendship is reflected in their fictional stories, and I?m backing up my examples with citations from their own diaries, letters and notebooks.
Hatten, dockan, capen, byrån : ting och tinglighet hos Djuna Barnes
The inhuman element in Djuna Barnes?s works has been widely acknowledged. So far the research has, however, concerned itself primarily with animality, thus neglecting the importance of things and thingliness in her texts. In this essay I outline a new way of approaching Barnes were things are taken into account as a vital element in her literary world, using theories on prostheses, fetishes and souvenirs. In Nightwood and four of the short stories, ?A Night Among the Horses?, ?Aller et Retour?, ?Cassation?, and ?The Grande Malade?, I examine clothing, interiors, collections, statues and dolls as objects that in different ways harbour meaning, dream, riddle, memory, history, longing and desire.
Överföring av digital video via FireWire
Transmission of digital signals is today more frequently used than transmission of analog signals. One reason for this is that a digital signal is less sensitive to noise than an analog, another reason is that almost all signals today are handled in a digital format. This thesis describes the development of a system that receives digital video signals through FireWire. The standard for FireWire, which is a high performance serial bus, is under development. Today the standard of the bus supports transmission of data with a speed of up to 400 Mbit/s.
Slusseneländet
Stockholm is constantly growing and changing. Despite this, for various reasons, it is difficult to execute large building projects. With starting-point in decision making theories we have tried to investigate these difficulties. More specifically we have chosen to study why it has not been possible to rebuilt Slussen in Stockholm. To help us structure our study we have based our research on another large comparable building project, the Globen City project.
