This master thesis is the documented work of the construction process and testing of a three hour laboratory session in mathematics aimed at high school level students. The purpose of the thesis was to create an interesting laboratory session for the science education center ?The House of Science? that could be used as a part of their regular program directed to schools. The thesis explores the possibilities for how one can construct a laboratory session on the topic ?molecular symmetry? as well as the underlying pedagogical theories used to describe learning processes in creative contexts.

Hemoplus® (Sarstedt, Nümbrecht, Tyskland) is a guaiac-based fecal occult blood test developed for human medicine. Guaiac-based tests make use of the pseudoperoxidase activity of hemoglobin so the test is not specific for human hemoglobin and can therefore be used in veterinary medicine. Peroxidase-containing foods such as meat (hemoglobin and myoglobin) can cause false-positive results of the test. To ensure that a positive result is not caused by diet, it has been suggested that canine patients should be fed a meatless diet for a few days prior to fecal occult blood testing. The aim of this study was to evaluate the effect of commercial dog food on guaiac-based tests. In this study fecal samples from healthy dogs were analyzed with Hemoplus®.

The thesis work of 15 credits has been performed to interest of Norrtälje ElektronikPartner AB (NEP) in Norrtälje. The aim of the thesis was to develop a prototype for an integrated digital multimeter, designed for one of NEP's proprietary test systems. A digital multimeter module according to NEP's requirement specification, such as physical size and accuracy should be constructed. The module should be able to measure current, voltage and resistance.The final circuit was based on the chosen analog to digital-converter, Maxim integrated´s Max134, which is the main component of the circuit for this instrument. A circuit diagram and PCB layout were made. The result of this project is a constructed DMM board.

The purpose of the literature study was to describe older people´s difficulties and attitudes to take several drugs. Literature has been sought in two large databases and included literature is selected, quality assessed and analyzed, based on the study purpose and questions. The authors conducted a descriptive literature review of qualitative and quantitative articles.

Bakgrund: Förekomsten av STI såsom gonorré, hepatit B och C, HIV, AIDS, klamydia och syfilishar under de senaste åren ökat i Sverige. Studier visar att långt ifrån alla som utsatt sig för smitta ellerhar symtom på STI går och testar sig. Dessutom visar studier att vårdpersonal ibland nekar individenSTI-provtagning trots att detta inte är tillåtet. För att underlätta barnmorskans arbete medanamnestagande vid STI har det utvecklats ett frågeformulär inför STI-provtagning. Det saknasdock information om barnmorskors åsikter vid användandet av frågeformuläret.Syfte: Syftet var att utvärdera barnmorskors åsikter om frågeformuläret ?Frågor inför STIprovtagning?på barnmorske- samt ungdomsmottagningar i Göteborg och södra Bohuslän.

Mobile Arts have a technical platform for handling maps and community-featured Points of Interest in cellular phones, where the users themselves can share locations with other users either in groups or public. Development of the platform regarding network communication has been included in this paper. The work evaluates different feasible business models regarding packaging the platform as a commercial application and also faces issues users have when using the product. Even if users found maps and POI interesting and cool in cellulars, the technical difficulties and lack of product focus during beta testing, were present. Therefore, the writers recommendation is more development of the platform and using a business model where Mobile Arts deliver to existing communities.

The aim of the study was to illustrate how music therapy can be used in the care of patients with schizophrenia and other psychotic illness.The method used was a literature review. Scientific articles were searched in PubMed, Cinahl, PsycINFO och Scopus databases with an outcome of ten articles, with in total 330 participants, that underwent quality and outcomes analysis.The results showed that music therapy could provide potential improvement in the patients' social functions and that it could also improve negative, some positive and general schizophrenia and psychotic symptoms in some patients.
