This study was a final thesis, for the bachelor program in civil engineering at theUniversity of Uppsala, which was made on behalf of Riksbyggen in Uppsala. Acomparative study of two stain renovation methods; tradition pipe replacement andrelining was done with an environmental perspective. A simplified life cycleassessment (LCA) was done according to the International Organization ofStandardization (ISO) with the LCA tool Eco-indicator 99, in order to be estimate theimpact on the environment. LCA is a method that follows a product or a system?from the cradle to the grave?, which means that all the environmental impact over alifetime is considered.The work was executed by using a stairway with nine apartments in a house called?Uppsala Hus 9? as a reference object, which was provided by Riksbyggen.

This report is of technical character and treats how to plan a small building in Borlänge, Sweden.The technical components that have been treated in the report are the construction, foundation,installations and thermic abilities of the house. In addition to planning this house the report alsocontains a part that deepens in net zero energy buildings. The purpose of the report is toinvestigate if the house in Borlänge can be constructed to meet net zero energy buildingdemands.Energy efficient houses such as passive- and net zero energy houses are showing more frequenton the market in Sweden. Ongoing climate changes and growing consciousness about theenvironment in society have contributed to that the environment is a well discussed topic. Toconsume small amounts of energy and at the same time produce local energy is thereforesomething that lies in the future and future houses.

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

The purpose of this study is to explore the factors affecting an individual's working life mobility and how this mobility is perceived by the individual. The study has a qualitative approach and the theoretical part is based on Castells', Giddens' and Bauman's theories of modern society and employment in relation to the individual. The study concludes that external circumstances in combination with internal driving forces are the reasons behind changing careers. The process is predominantly perceived as positive, especially education tends to strengthen self-identity. Work in general is regarded as important for a person's identity and new career changes are expected in the future..

Regional European Offices with the purpose to represent regions and municipalities in the EU-system have had a substantial expansion over the last years. One example is the North Sweden European Office for the counties of Norrbotten and Västerbotten, consisting of seven different headmen who are representing both the private sector as well as the public system. This diverse leadership representation makes North Sweden a very good example on a so called Quango, organisations that stand under simultaneous influence from both public and private sectors. These Quangos opens up new possibilities to solve public problems, but they also bring together two different working models which is not always easy to handle for a Quango. According to earlier surveys some characteristic Quango problems within North Sweden exist, for example the ability to prioritize and thereby be as effective as possible.

Idag är intresset för högpresterande betong (HPB) växande runt om världen då fördelarna är många, eftersom slankare, tätare, starkare och lättare konstruktioner kan tillverkas. Detta examensarbete handlar om materialförsök och modellering för en typ av HPB som ska användas i husbyggnation. Arbetet inleddes med materialförsök i färskt tillstånd, där god gjutbarhet och konsistens eftersträvades. Utgångspunkten var från ett grundrecept med två olika ballastsorter (slaggballast med flygaska och krossballast från asfaltindustrin med silikastoft), vilka namngavs till pilotförsök 1 och pilotförsök 2. Vidare valdes pilotförsök 1 att provas i hårdnat tillstånd då det visades att det var mer ekonomiskt lönsam eftersom ballasten inte behövde siktas, lägre vct tillhandhölls och att flygaskan som användes i pilotförsök 1 är billigare än silikastoft som användes i pilotförsök 2. Resultaten efter 28 dygn för de materialförsök som utfördes i hårdnat tillstånd var:Tryckhållfasthet; 141,9 MPaDraghållfasthet; 7,0 MPaBöjdraghållfasthet; 10,0 MPaElasticitetsmodul; 46,4 GPaKrympning efter 56 dygn; 0,5 ?Samtliga försök utfördes enligt svenska standarder (SS). Dessutom vidareutvecklas och förbättrades ett redan arkitektoniskt gestaltat Attefallshus ur ett konstruktions- och hållbarhets perspektiv, där fokus låg på transport- och produktionsförutsättningar.

The aim of this paper is to describe the characteristics of the sport journalistic weblog. To achieve this we have used the following questions: Which themes are included in the sport journalistic weblog? How much text does the sport journalistic weblog content? How often is multimediality incorporated in the sport journalistic weblog? Which references occur in the sport journalistic weblog? How many hyperlinks occur in the sport journalistic weblog? How many of the hyperlinks is internal respective external? How often does the sport journalistic weblog offers possibilities to interaction between the journalist and the reader? How often does interaction between the journalist and the reader occur?The theories we have used is both online publishing and Jan Schmidt?s analytical framework on blogs. Online publishing describes an important part in our paper, online journalism, which in turn describes three important definitions for this paper; hypertextuality, multimediality and interactivity. Jan Schmidt?s theory is central to understand the phenomena, and functions as a starting point in the analyze part.

In the world after the Cold War, internal and ethnic conflicts have been predominant. Ethnic conflicts have their own theories on why they erupt and what can be done to solve them. This essay seeks to analyze how the Ethnic Security Dilemma can explain the causes, and possible solutions, of today´s armed ethnic conflicts.By making an ideal types typology over different types of ethnic conflicts, and then analyzing the Ethnic Security Dilemma´s impact on each conflict type.

In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed.Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound.These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile.

It also covers a review of different models to use in order to achieve an internal cloud. Suggestions on how to proceed with the change process are also provided, and which models might be appropriate for the specific company..

In 1993 Sweden introduced a new Forest policy, with a larger freedom of action for the forest owners, but in the same time the forest owners are expected to take greater consideration of the forests and the environment, that is required by the law. This is necessary to be able to obtain the goals of the new policy. Therefore the demand for competence and guidance is larger than before. At the same period of time organisations where slimmed and trimmed during a economic recession and the question is how this has affected the number of employees on different levels in the organisations, the competence of the employees and their internal education and if these changes affects the possibility of implementing the forest policy. This study contains three points in time where measures were made, 1990, 1995 and 2000.
