Effektivisering av kvävereduktionen i en konstruerad våtmark avsedd att behandla avloppsvatten
On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.

Förnyelsebar plast från rapshalm
Efterfrågan på förnyelsebara och miljövänliga produkter har ökat under de senaste åren. Biobaserade plaster anses vara en av de mest lovande innovationer. Det övergripande målet med examensarbetet var att undersöka möjligheterna att utvinna xylan och glukomannan ur rapshalm. Metoden som utnyttjades var en hydrotermisk extraktion. Inverkan av temperatur, pH och tid studerades genom att tillämpa ett faktorförsök på två nivåer.

Informationskrigföring : den nya teknikens hot
The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation.
Brands Transfer of Meaning: An analysis of brands roles within product placement
Thesis purpose: The purpose of this thesis is to make a contribution, by connecting the transfer of meaning within the context of TV series. The meaning is transferred from the brand to the character in a TV series and then further to the viewer. To look at different role functions that are used in dramaturgy and narrative techniques, we will be able to see how the brand will have a specific role and thereby make the transfer of meaning more successful and effective. This role will have an important impact on product placement according to the meaning that will be transferred from the brand to the viewer, through the character. Methodology: By looking at the transfer of meaning process that is created from the brand, an unstructured observation is applied where we observed the placement and usage of different within a specific TV series.
Socialsekreterare och stolt? : En kvalitativ studie om socialsekreterares yrkesstolthet
The aim of this thesis is to study whether social welfare secretaries experience occupational pride and what affects this feeling. Previously made research indicate that occupational pride is essential for performance and work-related health. Research has also shown that social welfare secretaries often experience unhealthiness due to working conditions and a lack of professional self-esteem.This thesis is based on four qualitative interviews which have focused especially on critical incidents, according to the critical incident technique. This study has a hermeneutic, interpretative approach. As a theoretical framework, Pierre Bourdieu? s theory on social space and positions aswell as Aaron Antonovsky´s theory on Sence of coherence have been used. The result shows that the interviewed social welfare secretaries do experience occupational pride.
Revidering av rockdatabas
Svenskt Rockarkiv is an organization located in Hultsfred, Sweden. Its goal is to collect and document the history of Swedish rock music. The archive contains several types of documentation, such as audio recordings, photographs, posters, video recordings and books representing Swedish rock music history. In order to store information about the audio recordings in the archive, Svenskt Rockarkiv uses a SQL Server 2000 database and a client application written in Microsoft.NET C# and Windows Forms. The purpose of this degree project is to audit the database and windows client, since the organization has needs of new functionality.
Measurement of ejection fraction of the left ventricular - A comparison between echocardiography and isotope angiography
Background: Documents and legislation inform us that parts of the public health service of Sweden, at a political level, aim to support people?s sexual health. Statistics show there has been an increase among young woman, seeking help for sexual pain during intercourse. The diagnosis that the media has come to observe lately is vulvar vestibulitis. In general there is a lack of knowledge about the existence of this state of pain and its causes, which impacts woman to get appropriate help and support in time.
Naturanpassat bostadsbyggande :
I am in this essay to find out how to successfully combine new development with preservation of natural values, mainly large scale vegetation and ground formations.This is done by studies of three developments.
The first development, Engeltofta backe, lies 7 km northeast of Gävle. The expectations of natural preservation were not fullfilled when this area, after the explotation, did not have any vegetation of value left.
The second example, Östra Kvarnskogen in the community of Sollentuna, shows, as far as one can tell at the moment, a sucsessful combination of new development and preserved nature.
The third example is a development in the community of Kullön. In this area the ambition of combining preservation and development was fullfilled.
After studying vital documentation in each planning process, I made interviews with different actors in each of the three processes. I thereafter compared the different documents and answers from the interviewed persons to find out if there were any significant similarities or differences which could be of importence when natural values is to be preserved in new developments.
My conclusion of this study is that it is of great importence to define key expressions often used in the process, such as natural values and preservation.
Fosterdiagnostik vid MR-undersökningar - gravida kvinnors upplevleser och magnetkamerans påverkan på fostret.
Introduktion: Fosterdiagnostik med magnetkamerateknik (MR-teknik) har utvecklats mycket den senaste tiden och använts som en kompletterande metod till ultraljudsundersökning. Magnetkamera ger ingen joniserande strålning till patienterna, samt ger en mycket mer detaljerad bildinformation än vad andra metoder gör. I samband med MR kan de gravida kvinnorna uppleva olika psykiska påfrestningar genom både själva MR-undersökningen och oro för barnets hälsa. Även om MR-fosterdiagnostiken anses vara en säker undersökningsmetod för fostret föreligger det ändå en ovisshet angående de effekter som kan förekomma. Syfte: Syftet med examensarbetet är att genom publicerad forskning få kunskap som kan utveckla röntgensjuksköterskans möjlighet att ge optimalt stöd och information till gravida kvinnor vid fosterdiagnostik med MR-teknik utifrån följande aspekter: 1.
