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.

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.

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.

A Green Belt of synergies : a study on the implementation of a contemporary Green Belt

The prevailing urban migration is a worldwide process. This results in growing cities and a diminishing proportion of people living in the countryside. As the urbanization continues a large amount of the world?s population is expected to live in urban settlements of informal character by 2050. Green Belt has for many years been used to control urban growth and to secure the sustention of larger green areas around towns and cities.

Jämförelse mellan populära molnlagringstjänster : Ur ett hastighetsperspektiv

Molnlagringstjänster används alltmer och är en växande marknad. Uppsatsen har fokuserat på att undersöka olika molnlagringstjänster ur ett hastighetsperspektiv. När små filer utbyts mellan klient och server har hastigheten på överföringen en mindre betydelse. Vid större överföringar får hastighetsaspekten en alltmer viktig roll.Regelbundna hastighetsmätningar har utförts mot de mest populära molnlagringstjänsterna. Testerna har utförts från Sverige och USA.

För ung för att dö : En litteraturöversikt baserad på yngre patienters tankar om hur de hanterar att leva med cancer

Background: Approximately one in three Swedish people will receive a cancer diagnosis. Cancer primarily affects the elderly but also young people suffer. Young people are in a period of life that could put a strain of the ordinary when they are faced with choices and new challenges. The basic sense of security in everyday life is not so obvious and many suffer from, for example, stress and the feeling of being inadequate in relation to the requirements. It is relevant that the nurses can put themselves into what it is like to be young and afflicted with cancer, with the pressures of life itself and what the disease represents.

ETL-processen : teori kontra praktik

AbstractNowadays, companies and organizations manage large amounts of data to be used as support in decision making. A good solution for data management is in the form of data warehouses. A data warehouse is used to gather information from multiple sources within a company and arrange the information in a way that makes it easy to retrieve and analyze. Designing a data warehouse is not a simple task. The study herein will focus on what a data warehouse is and how the ETL process is used for data storage in the data warehouse. ETL stands for Extract, Transform and Load and is the process that retrieves data, transforms it and finally loads it into the data warehouse.

Utredning och förslag på ett nytt materialförsörjningssystem : Företagets egentillverkade komponenter

Zetterberg's Industri AB believe that capital and lead time will be reduced by implementing Kanban. Therefore, it was an investigation to prove that Kanban is an effective method. In this work a research had to be done to show how the material supply system looks like today and to explore the subframe components to see which components that are interesting from Kanban viewpoint. Previous orders of subframes were investigated. Therefore, it was a list of the various components of the previous orders for the subframe.

Aktiv förvaltning : en utvärdering under volatil tid

Over a long period of time, there has been a rich debate in the academic and financial world if active management can generate an excess return. Many experts say that the current active management strategies is nothing more than a money grab that produces large gains, for banks and investment firms, through high management fees while producing no excess value for the individuals buying their service. In short, an effective market makes it almost impossible for fund managers to produce value for their clients in the long run.No argument has only one side though, other experts say that active management has a role to play because not all investors are rational. This irrationality can lead to mispricing on financial assets in the marketplace and in turn lead to an ineffective market where active management can fill a much needed role. The purpose of this study is therefore to see if active management strategies can create a higher risk adjusted return, taking management fees into consideration, during times of high volatility when the uncertainty is at its peak.

Somaliska pirater - ett mycket litet problem: En undersökning av Sveriges arbete gällande frågan om somaliska pirater under 2009-2010.
