Keratitbehandling, antibiotika versus corneal collagen crosslinking (CXL) genom riboflavin och UVA

Syfte: Syftet med denna studie var att jämföra antibiotikabehandling med corneal collagen crosslinking (CXL)-behandling genom fotoaktivering av riboflavin vid bakteriell keratit. Att experimentellt undersöka om en viss stam av Pseudomonas aeruginosa kunde infektera cornealt epitel var också en del av studien.Metod: Litteraturstudie samt ett experiment med Pseudomonas aeruginosa och grisögon in vitro.Resultat: Dagens behandling av keratit är initial med antibiotika. I experimentella studier har CXL använts både i kombination med antibiotika och som enskild behandling. Positiva resultat från studier med CXL som behandling mot keratit har rapporterats.Resultatet av det experimentella försöket pekar på att den stam av Pseudomonas aeruginosa som användes i experimentet inte kan penetrera ett intakt epitel.Slutsats: CXL kan bli en viktig och användbar behandlingsform vid keratit, särskilt med tanke på den ökade antibiotikaresistensutvecklingen. Ytterligare forskning på området krävs dock innan metoden kan bli fullt vedertagen.För att kunna fastställa om stammen av Pseudomonas aeruginosa i det aktuella experimentet har virulensfaktorer för att ta sig in i ett oskadat epitel eller inte krävs fler försök..

Management of Private Equity Investments: A Study of Swedish Biotech Investment Managers

The Private Equity industry has over the past years been booming and major external environmental changes have made the industry transform rapidly. Increased competition between Private Equity firms is one of the reasons why the industry has been and is being forced to focus more on addition of value through increased operational management. Consequently, the focus of value addition is by some said to be transferred away from deal making and financial skills, and into active operative management. This case study investigates how the portfolio management, and more specifically the measuring and management of performance, is carried out in a number of leading Swedish Private Equity funds with investments in the biotech sector. The biotech sector is characterized by extensive research and development, and many biotech companies often lack income and other measurable financial parameters in the initial phase.

För den goda sakens eller smakens skull?: En studie om vad som driver konsumenter i valet av ekologiskt vin

Concerns for the environment and our impact on it are becoming more prevalant; however, we rarely act accordingly. Consumers mainly choose products based on perceived personal benefits despite the environmental motives that increasingly affect them. The purpose of this thesis is to identify the major drivers behind the purchase of ecological wine. A quantitative study was conducted, using Theory of Planned Behavior (TPB) as an initial starting point. The subsequent model was then completed with three variables: environmental concern, feelings and word-of-mouth.

Det (väst-) europeiska samarbetet - från säkerhetsdilemma till stabil fred

In this essay the morphing of the interstate relations in the post-World War II Western Europe is taken in to consideration in discussing how these relations were stabilized and consolidated through community cooperation to achieve a state of stable peace. It concludes that the early 1900's of Western Europe comes close to being conditioned by Herz's security dilemma and then continues to analyze the development from this state to one of stable peace. In this analysis pivotal features of the ECSC, EEC and the EC are being scrutinized through the use of Boulding's Stable Peace theory and developments of the very same, in separate case studies, in order to account for the Communities? influence on the peace process.In doing this, conclusions are drawn that external pressures can be very effective in creating an incentive to move beyond an initial state of conflicting self-images and that a stabilizing process has got to provide a long term solution in order to sustain a trustful relationship. In order to provide this long term solution the community cooperations suggests that locking in through institutionalization, harmonization, and the creation of a state of irrevocable interdependence are highly effective..

"Våld som våld... skulle jag tro": Kvinnojourers förhållningssätt till våld i samkönade relationer mellan kvinnor

The purpose of this thesis was to examine women's shelter representatives' views on domestic violence in same-sex relationships between women. The questions we posed were how women's shelter representatives relate to same-sex domestic violence, both from a theoretical and practical perspective, as well as if they are, or feel they should be, inclusive of women who are victims of same-sex domestic violence.We conducted a qualitative study, in which we interviewed eight women's shelter representatives. We then compared and linked our findings with previous research, including studies on the occurrence of same-sex violence, and ideas of similarity and differences between men's violence against women and same-sex domestic violence. We also linked our findings to theories on heteronormativity and structural theories surrounding same-sex domestic violence.We found that the competence and knowledge of women's shelter representatives varies greatly from individual to individual. Heteronormativity permeates the organisations to a great extent, from exclusive marketing and initial reception to a lack of interest regarding these issues.

HUR CIRKULÄR EKONOMI KAN IMPLEMENTERAS I SMÅ OCH MEDELSTORA FÖRETAGS PRODUKTUTVECKLING

Dagens trend av industriell tillverkning och konsumtion är av linjär karaktär. Material utvinns, blir produkter och hamnar sedan på deponi. Detta examensarbete har tillsammans med Industrial Development Center AB syftat till att skapa en mer hållbar industriell tillverkning inom Skaraborgsregionen, genom att forma en produktutvecklingsprocess i enlighet med cirkulär ekonomi. Cirkulär ekonomi förespråkar att avfall inte får förekomma och att produkter och material ska cirkulera i kretslopp. Projektet bestod därför av en bred förstudie för att samla och utvärdera ett stort område med teorier, processer och företagens ansvarsroller.

Surveillance of Geomyces destructans in Swedish bats and Bat Hibernacula

White-Nose Syndrome, WNS, is an emerging fungal disease in the Northern American bat population causing mass mortality in infected hibernacula. Geomyces destructans is a newly discovered psychrophilic fungus causing WNS but the pathogenesis and epidemiology of the disease is not yet fully clarified. Geomyces destructans has been found in Europe but has not been a cause of mass mortality there. This study is the first investigation done to see if G. destructans is present in Sweden.

Vägen till den grönare sidan leder över forsen : En tematisk analys av destruktivitet och strävan efter konstnärskap i August Strindbergs Röda rummet

The aim of the essay is to analyze destructivity and the aspiration of artistry in August Strindberg´s debut novel Röda rummet. By the method of close reading the thematic analysis is performed. The method is also based on an hermeneutic way of looking at literature.A historical context is adapted and the characters are compared to historical descriptions of artists such as bohemians, decadents and dandys. The artists of the novel prove to be, like the bohemians of the 19th century, standing outside and against society, although the presence of relations and cultural exchange seem to be just as important. There is also an ambivalence to be found in their relationship with the city and it´s lifestyle.The question at issue is how the development of the characters´ artistry come about, and in what ways the characters are influenced.

Framgångsfaktorer i nystartade bioteknik- och IT-företag

Syftet är att analysera vilka variabler som påverkar performance positivt i nystartade BioMed och ITT-företag och i denna process även beskriva och jämföra hur dessa variabler ser ut i de två branschgrupperna och hur företagen har utvecklats. Vi har använt oss av en kvantitativ metod och har genom ett enkätutskick fått empiriskt material från 20 grundare av BioMed-företag och från 30 grundare av ITT-företag. Slutsatserna är att i BioMed påverkas nystartade företags performance positivt av: grundarens ålder, arbetserfarenhet, branschkunskap, start-up-erfarenhet och ett heterogent nätverk. Nystartade ITT-företags performance påverkas positivt av : grundarens ålder, utbildningsnivå, arbetserfarenhet, branschkunskap, antalet grundare, initial kapitalmängd i företaget och att ha affärsänglar och riskkapitalbolag som kapitalkälla. Connects olika insatser får generellt sett inte bra betyg av grundarna och därmed drar vi slutsatsen att Connects betydelse för företagens performance inte är stor.

Storjuktan ? Rekonstruktion av ett sekels kvicksilverbelastning. : En undersökning av kvicksilverkoncentrationer i daterat bottensediment.

The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.

Analys och kontroll av hållfasthet på grenställsarm

The thesis was done in collaboration with EAB situated in Smålandsstenar. In the initial discussion faze on doing a thesis with them there was a need to analyze and ensure the strength of an existing product, cantilever racks. This included performing FEM calculations on a model and comparing the results with physical tests.EAB has two models of cantilever racks, a light duty and a heavy duty. Within the heavy duty model series there are five product variants that differ in both size and load capacity. We will be working with the product variant with a load capacity of 1000 kg/arm which is the variant that is in the middle of the series.When we started work on the thesis we did a literature study and couldn?t find any well defined methodology that integrates both product development and computer aided design analysis.

Prissättning av IPO:s på den svenska aktiemarknaden

Title: Pricing of IPO:s on the Swedish stock market Authors: Mikael Gustavsson Martin Kvist Henrik Wannberg Tutor: Anders Hederstierna Problem: There are certain sets of problems for underwriters when they are pricing potential stock-exchange companies. The problem partly consists of estimating the demand at an IPO and also to accurately value the business in comparison to the market. To set the price per share is problematic, since the company carrying out the public offering wants to optimise the amount of capital at the same time as they want the share to be subscribed in full. If the IPO would not be carried out, it could cause harm to the position of the underwriters. Purpose: To investigate whether underpricing exists associated with IPO:s on the Swedish market during the period 1995-1999. Method: The collection of data has been achieved by means of: Internet, E-mail and telephone calls. Conclusions: We have reached the conclusion that oversubscribing in comparison to the return at an IPO has an average growth of 3.3 per cent the first day, on every occasion of oversubscribing. For the studied population, including 138 initial public offerings, the average market value rise is 15 per cent the first day. When we made our calculations, adjustments have been made for the general index of Affärsvärlden (AFGX).

Effektiv ordinlärning? : En studie av aktiv ordinlärning i engelska inom gymnasieskolan

The purpose of this essay is to discuss and compare different ways of learning new words and expanding your vocabulary in a foreign language. This is done by an examination of relevant literature and available research, as well as by an empirical study with two upper secondary school classes, in which two different methods are put to the test: one traditional method of the kind that is found to be most common in second language acquisition, and one designed to take existing research into account. The results show that, although effective in the initial stages of acquisition, the traditional method, where words are learned in isolation and via translation to L1, results in a very limited form of knowledge. A big part of the words acquired via this method is also forgotten soon afterwards. The other method, where words were learned and tested in its proper context, was found to result in a broader form of vocabulary knowledge, covering more aspects, and that remained over time.

Automatisk query expansion: en komparativ studie av olika strategier för termklustring baserade på lokal analys

Automatic query expansion has long been studied in information retrieval research as a technique that deals with the fundamental issue of word mismatch between query and document. The purpose of this thesis is to compare the retrieval effectiveness of different strategies for automatic query expansion. The strategies are based on local analysis of the corpus and use statistical information from the local document set to extract terms that suppose to adapt themselves to each individual search and therefore appear to be searchonyms to the index terms. The strategies compared are: association clusters, metric cluster and scalar cluster. Baseline queries of 24 topics are expanded using terms from the different clusters and searches are made.

Förebyggande av smärta vid propofolinjektion : Jämförelse mellan lidokain och remifentanil

Propofol is an intravenously administered, hypnotic and short- acting pharmaceutical. One common sideeffect (>1:10) and therefore a disadvantage with propofol is the local pain that arise when the initial injection is given. Why the pain arise is not clearly understood. A majority of different pharmacological treatments, different doses and combinations, alternative administrations methods and physical interventions have been tried to reduce the pain when injection of propofol is given. One important task for the nurse is to relieve pain for patients.
