Tjänligt vatten i kranen - Membranteknik gör det möjligt : En utredning av pilotförsök i Glemmingebro
Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant. In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

Systematiskt arbete för att hantera osäkerheter vid mätning : vid Q-Med AB i Uppsala
This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.

Konstf?rst?relse/F?rst?relsekonster: En unders?kning av konstruktiv ikonoklasm som konstn?rlig process
Building on the concept of constructive iconoclasm as a creational force of iconicity, this thesis examines how the contemporary iconoclastic discourse is related to artistic process.
Studies have shown that the performative act of destroying art that is an historical phenomenon is highly present within the contemporary art discourse today. Due to the many dimensions of contemporary art, the ways in which iconoclastic deeds appear may differ from the historical narrative. While iconoclasm and iconicity are being reciprocal processes that can only exist in relation to each other and their context, there are signs that the destructive act itself is being recontextualized by contemporary artists. Guided by the framework of Norman Fairclough?s critical discourse analysis, the thesis examines the processes of conceptual and constructive art destruction by analyzing the discourses of two case studies situated in the contemporary art market.
Integritet och långsiktig användbarhet hos textdokument : En avvägningsproblematik vid digitalt bevarande
This thesis is about a potential trade-off between integrity and long-term usability in the choice of file formats for preservation of text documents. Five common formats are discussed: plain text, PDF/A, Office Open XML Document, Open Document Text, and Markdown. The formats are compared with respect to four criteria related to integrity and usability and to the records continuum model: support by widely used software, stability, rendering of contents and reusability.It is concluded that no single format is optimal with respect to all four criteria, when it comes to preserving typical documents in a modern environment, with more or less complex formatting and document structure. Therefore, the feasiblity of using two or more formats for preservation of a single document (e.g. PDF/A combined with Markdown and/or Office Open XML) is discussed.
Kan coreträning påverka upplevelsen av smärta i nacke, axlar och skuldor? : Fyra veckors hemträning med övningen "plankan"
Syfte och frågeställningar Studiens syfte var att undersöka om utförandet av en isometrisk bålstabiliseringsövning/coreövning kunde påverka upplevelsen av smärta i nacke, axlar och skuldror hos kvinnor med kronisk/långvarig idiopatisk smärta. Studiens frågeställningar var: Hur påverkar utförandet av övningen ?plankan? upplevelsen av smärta i nacke, axlar och skuldror hos deltagarna? Förändras den maximala uthålligheten i övningen mellan deltagarnas första och sista träningstillfälle? Kan interventionen fullföljas av deltagarna?Metod Fyra kvinnliga deltagare som alla hade kronisk/långvarig smärta i nacke, axlar eller skuldror utförde övningen ?plankan? som hemträningsövning under fyra veckors tid. Mängden träning dokumenterades i en träningsdagbok som deltagarna kontinuerligt fyllde i under träningsperioden. Före samt inom en vecka efter träningsperioden ifylldes en enkät med frågor om upplevd intensitet, frekvens och lokalisation av smärta.
Hur konstrueras användare och bibliotek på svenska folkbiblioteks webbplatser ur ett webb 2.0- perspektiv?
The aim of this thesis is to find out how users and libraries are constructed at public library websites in Sweden from a web 2.0 perspective. We discuss the development of public libraries in Swedish history and the change from an system oriented perspective to a individual oriented perspective and how these perspectives correspond to needs of the library user. We also discuss the concept of web 2.0 and library 2.0. These concepts are open for different interpretations. Some writers believe that web 2.0 and library 2.0 is something radically new and that it will change the public libraries, while other writers claim that these concepts is just a marketing plan.

Optimala reduktionsgränser för kalldragna rör : Optimal reduction limits for cold-drawn tubes
Dragbänken installerades på avdelning kallbearbetade rör på Ovako i Hofors 1990. Sedan dess har kvalitetskraven på de dragna rören ökat. Samtidigt har produktivitetskraven ökat, det vill säga att tillverka rör till rätt kostnad. I produktionsplaneringsprogrammet finns gränser och regler för hur de dragna rören ska tillverkas för att rätt kvalitet och kostnad ska uppnås. Eftersom både de dragna rören och de varmvalsade ingångsrören har ändrats med åren så stämmer inte alltid gränserna och reglerna idag.
