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.

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.

By submitting a questionnaire to all professions within the groups I have tried to find similarities and differences in their statements from both structured and unstructured questions. The study is an attempt to contribute knowledge about how these groups can be understood and developed, based on a special education perspective, systems theory and sense of coherence (KASAM). The results shows that there is a consensus among the majority of staff opinions of the systems? opportunities as well as dilemmas.

 Extra high requirements are made on all systems in health care that they are functional and usable,´something, however, that is not always the case. At Emergency Admissions at Sahlgrenska University´Hospital many systems are in use at the same time and it happens that much overhead is caused by having to fill in the same information in different places. In addition, data that is gathered is to a large extent saved in free text format, which means that it cannot be used in a larger context such as research, quality control or for decision support. Data is saved in the patient file only for the treatment process of the individual patient.A data collecting system with decision support functionality could be a first step towards reducing Emergency Admissions? costs and patients? waiting times by providing a structured method of data collection.

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

Design principles are usually used by interaction designers to help creating a user friendly design by making the designer think about the different aspects of the design. These design principles has been further developed since they emerged in the 1990s, and today they're often used in the field of interaction design. By using the design principles, bad design can be avoided and the frustration of the user reduced. Design patterns is described as structural and behavioral characteristics to improve the environment in user interface amongst other areas. These characteristics could make things easier to understand or improve their appearance, they make tools more usable.The purpose with this essay is to identify design guidelinesto be used by developers when designing surveillance systems.

The purpose of this thesis is to investigate how Digital Signage systems such as public info kiosks can be designed to better fulfill its main use; to enlighten, encourage and influence the public with information. The challenges presented from earlier studies shows that the public interests and goals, together with proper and relevant content displayed in info kiosks have impact on the attention the public have towards public displays. Qualitative methods such as interviews, usability testing and observations were conducted to further examine how a public info kiosk can be designed to draw attention and grow interest amongst students at K3, Malmo University. Usability testing were used on the digital prototypes that were developed to ensure that the gestural user interface meet the requirements of a proper interaction from the users. Important insights were made concerning; the attention and interest to relevant content, the aspects of the gestural user interface along with the placement of the info kiosk in terms of context.

Companies acquiring ERP systems are often dissatisfied with the project and therefore consultancy firms wish to make use of project models in order to achieve success in implementations. Since research on ERP implementations in service companies is limited, there is a need for mapping of critical activities in implementation projects in this line of business. Under these premises, the purpose of our master thesis is to develop a model for implementation of ERP systems, specified in activities, which can be used by mid-sized consultancy firms with mid-sized qualified service companies as customers.A literature study including project models, modern models and methodologies for ERP implementation, commonly existent activities, success factors and system development methods was carried out. Starting out with this, a theoretical model for ERP implementation was generated. In excess of this, a case study was conducted, where the implementation of the ERP system Microsoft Dynamics AX at the service company Eurostep, performed by the consultancy firm Medius, was studied.

The aim with this study was to examine which information sources are used by the librarians in the process of changing automated library system and why. Furthermore it was of interest to examine whether there are any correlations between variables environment, information quality, information availability, information need and information sources. I used a quantitative method that was carried out in form of a nationwide survey. Questionnaires were sent out to all the Swedish libraries that had change library systems sometime between the years 2000.

E-handelskunder vill ha möjlighet att handla snabbt och direkt oavsett tidpunkt eller plats. Därför är integration mellan e-handel och affärssystem viktigt för en lyckad e-handelslösning. Detta känner de flesta företag till och idag är inte tekniken något större problem. Att företag trots detta inte integrerar systemen beror på verksamhetsbaserade orsaker. De stora kostnader som integrationen i initialskedet medför anges också som ett skäl till att systemen inte integreras, kunskap saknas om de långsiktiga vinster som integrationen ger.

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.
