The purpose of this study was to evaluate enantioselective analytical methods by separation of the enantiomers of four drugs (citalopram, zopiclone, tramadol and methylphenidate) and their metabolites. The analyses were performed with HPLC-UV with columns whose stationary phases were based on macrocyclic glycopeptides (Chirobiotic V, V2 and T) and polysaccharides (Lux Cellulose-1, Cellulose-2 and Amylose-2).The Chirobiotic V column showed high selectivity for citalopram and its metabolites. High resolution was obtained using a mobile phase consisting of methanol, acetic acid and ammonia. High selectivity for the enantiomers of zopiclone and its metabolites were obtained on the Cellulose-2 column using a mobile phase consisting of acetonitrile and ammonium acetate buffer.The enantiomers of tramadol were separated with the Amylose-2 column. However, changes in the pressure arose, probably caused by the additive NH4HCO3.

The aim of this Masters thesis is to examine the use of IT, that is the Internet and other applications of personal computers, among seniors 65+. It also deals with issues of access to IT for seniors in public libraries. The theoretical background of the study consists of Rogers "Diffusion of innovations", Hektors categories of information activities, and the Swedish IT-commissions categories of motives and prerequisites for the use of IT. The research questions focus on factors motivating the use of IT, the extent and the purposes of IT use, the consequences and the barriers that IT-users experience, and views on IT in public libraries and IT courses, respectively. Qualitative interviews were carried out with nine senior IT-users.

This report describes an examination project made for the IT consultingcompany Sogeti. The purpose of the project was to develop and modify the translation tool Language Manager (LM) built by Sogeti to be used for translating applications. Employees at Sogeti considered some disadvantages with Language Manager, version 1.0 which among others was that language files for projects were saved at two locations. Partly in resource maps among with the source code of the applications and partly in a database. This was dual work for employees at Sogeti and it also caused redundancy inthe system.

New technological innovations like tablets and smartphones have a taken significant market share on the web and puts new demands on webpages, the user interface and compatibility among different client devices. The full test of a web-based system prior to the publication is often regarded as an important part of the process to create a complete and successful website. This bachelor thesis investigates the possibility to analyze mobile-adapted web sites using a system that first records the visitor's activities and then replays them for an expert analyst to provide valuable information to developers about how their site can be improved.The essay begins with a litterature study on today's most common web development tools and then examines the possibility to apply them during the development of the analysis tool. The work also describes two methods, pair programming and waterfall method used during the project. Three different evaluation methods are presented and one of the models is applied on the finished system.The project results in a web-based analysis tool written mainly in JavaScript using the jQuery library.

The purpose of this bachelor thesis is to find out how information seeking habits and experiences of people in different generations affects their expectations on information retrieval systems like OPAC. Two OPACs are used, one web-OPAC and one mobile-OPAC. The following questions are asked: how can theories about information seeking behaviors explain why and in which way one seeks information? In which way does information seeking behaviors and habits affect the experience of OPAC? Which differences and/or similarities can be found between the web-OPAC and the mobile-OPAC? How does generational aspects affect experiences and preferences in an information seeking context? The theoretical framework of the thesis is information retrieval with several models about information-seeking/searching needs and behaviors. The empirical data contains interviews with nine people in different generations and protocols about two different OPACs.

The Swedish parliament has decided that Sweden should increase its usage of renewable fuel sources to a level of 50% of the total energy consumption in Sweden by the year 2020. One way to reach that goal may be to increase the usage of stumps as a bio-fuel. In Sweden stump harvesting is possible on about 5-10% of the total harvested area and thus contribute with 1,3 - 2,6 TWh per year. An increase stump harvest doesn't come without its drawbacks for the environment. When harvesting stumps a tracked excavator is used to pry the stumps from the ground and then cut the stumps into smaller pieces.

The aim of this study was to analyse ninth graders self reported screen based activities, sedentary time and musculoskeletal symptoms and pain intensity. The other aim was to examine changes regarding musculoskeletal pain and inactivity between ninth graders from a cross sectional study in year 2004. To meet this aim, following questions were designed: How is the relationship between screen based activities, inactivity, musculoskeletal symptoms, pain intensity and differences between girls and boys? How have musculoskeletal symptoms and screen time changed since year 2004?Method: The method used for this study was a quantitative method. The research was carried out using a questionnaire that was answered by pupils from 11 schools from all over Sweden.

Studies of modern communication media such as Cell Phones and so called Instant Messengers are popular today. This study focused on these modern techniques, focused on parents as a target group and on what is important for them in everyday communication.By exploratory using three focus groups it became clear that the children, and the link to them was the absolute most important thing for the parents. It became clear that this link to a great extent today exists through the mobile phone.In a following study a Mobile Instant Messenger called My Friends was introduced. It was used by two families during two weeks to see how it would change the communication within the family. The focus was to see how problems with availability were handled, it turned out that:My friends had a more obvious way of indicating availability than the Cell Phone had.

The purpose for this Masters thesis is to describe childrens librarians work in supplying literature to children with emphasis on easy-reader materials. Our main questions are: · What do librarians believe characterizes an easy-reader book, and what do they base their decision on when classifying a book as easy-to-read? · How have the libraries in our study solved the hands-on difficulties associated with easy readers childrens literature? · Which factors do librarians consider to be important when supplying literature to children that are not used to reading or are not good readers? The theories we have used are Aidan Chambers Reading Circle and Karner Smidts view on the librarians professional roles when supplying literature. We have used a case study method, which means that we have gathered information through observation, objective papers and interviews. This has been done at six libraries.

SAAB Aerotech division FGR in Arboga builds and develops equipment and components used in both military and civilian applications. To build a test system for a specific project that SAAB is responsible for requires a simple signal generator that can provide a pulse modulated signal. The need to buy a new advanced signal generator for example from Agilent is not as profitable as the instrument is expensive and contains features that SAAB does not require in their applications and test systems. That was the reason why SAAB offers two students a thesis where the goal is to construct a signal generator in accordance with what SAAB requests.This thesis contains several different phases. The first step was a meeting with our supervisor Mats Bergman and by reading the data sheets for components to be used in the project, with these information and specifications that we have received from SAAB we started to construct the signal generator.What we did during the construction work was to simulate and draw a schematic to be able to design the circuit board.

Syftet med Utvecklingsprocessen är att den ska kunna användas som ett hjälpmedel under utvecklandet. Processen riktar sig framförallt till studenter och företag som inte har någon erfarenhet av att utveckla business-to-businessinriktade mobilapplikationer.Denna process tillämpas sedan praktiskt genom att ta fram en idé till en applikation.

This bachelor thesis aims to investigate how social workers in Uppsala describe their procedure when investigating applications for housing assistance (i.e. boendestöd). Boendestöd is a specific type of services for people with disabilities, which aim to assist them in their lives. This welfare service is one of many regulated by the framework legislation that is the social services act (SoL 2001:453). Previous research indicates that civil servants who make decisions based on goal-oriented framework legislations like SoL, have a great freedom to act when they make judgments and decisions.
