The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany. The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.

Vid extrema bergsaktiviteter som klättring och skidåkning ställs stora krav på utrustningen. Den här studien har fokuserat på skalplagg för alpin miljö. Skalplaggens huvuduppgift är att skydda mot vind och fukt samtidigt som de skall transportera fukt från insidan till utsidan. För att kunna designa och utveckla bästa möjliga skalplagg krävs det kunskap om vilken miljö produkten/plagget ska användas i, vem som ska använda det, hur mycket ska plagget användas, i kombination med vilka andra produkter/plagg och vilken kunskap har användaren? Det är också viktigt att förstå vilka materialkrav som ställs på produkten.

Sötvatten är en naturlig källa för atmosfärisk metangas. Gasen som bland annat bildasi sjöar och vattendrags sediment stiger upp genom vattenfasen via bubblor och diffusion och når därigenom atmosfären. Metangasen fungerar i atmosfären som en växthusgas då den inverkar på vårt klimat och är den gas som näst efter koldioxid bidragit mest till de sentida förändringara av den naturliga växthuseffekten. Förändringarna orsakas av att de klimatpåverkande gaserna ökar i atmosfären och som följd bidrar till en så kallad förstärkt växhuseffekt med globala temperaturökningar som följd. I denna studie har metanemissioner till atmosfären undersökts från vattendrag, nämligen Stångån, som rinner genom Östergötland och mynnar ut i sjön Roxen.

Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.

The aim of this study was to detect antibodies in swine serum against proteins in soy beans, wheat, oat and barley. Two methods were used: agar gel immunodiffusion test (AGID), and SDS-PAGE followed by immunoblotting. The sera examined originated (I) from piglets younger than one week (negative control), (II) pigs from a feed trial with soy bean in a herd with PMWS, and (III) pigs inoculated with Brachyspira hyodysenteriae and Escherichia coli after being fed with soy. The AGID-test was negative concerning all examined sera which were analysed against proteins in soy bean, wheat, oat and barley. In the experiment based on immunoblot antibodies were demonstrated within all three groups of examined pigs.

A sample of milk inoculated with S. aureus was treated with penicillin, and Antipen (a new commercial product containing penicillinase) was added. To another sample with S. aureus and penicillin, formic acid to pH 5 was added, and to yet another sample, a combination of formic acid and Antipen was added. Controls with no penicillin were treated in the same way.

This thesis treats the normative power of the European Union and its affect on Macedonia. The main purpose has been to look closer with the use of the application of Ian Manners theory of normative power on the Macedonian case. The focus will be to answer the following questions: Does the European Union act as a normative power in relation to Macedonia, if so, how are these values diffused? Has there been any effect of the spreading of these values? Based on six interviews and the available material of European Union strategies for the Macedonian membership I have attempted to understand to what extent the European Union?s normative power has had an influence in Macedonia. The result of my analysis is confirmation of the European Union as a normative power in Macedonia and the understanding of the methods of application..

The purpose of this study was to investigate the occurrence of Verotoxin-encoding bacteriophages in mussels, cultured downstream the sewage treatment plant in Lysekil.Mussels were collected in three growing areas from April 2008 to March 2009. Real-time PCR was performed for detection of vtx1 and vtx2 genes and enrichment of bacteriophages on non Verotoxin-producing Escherichia coli O157: H7 was carried out. All samples in real-time PCR analysis were negative; no presence of Verotoxin-encoding phages was shown. No plaque was formed on blood agar base plates, indicating that no bacteriophages had been taken up by E. coli bacteriaThe levels of Verotoxin-encoding phages and E.coli outside the sewage treatment plant in Lysekil were not high enough to be able to form VTEC in mussels, indicating that the faecal contamination was low.

The aim of this study was to establish knowledge about the most suitable substrate for cultivating different kinds of anaerobic beer spoilage bacteria in the brewing industry. During the study, two other aspects were investigated; if the sample volume affects the results and which anaerobic beer spoilage bacteria are present in the micro flora at the brewery. The method used was standard cultivation with four different substrates; Universal Beer Agar, Nachweismedium Bierschädliche Bakterien, Raka Ray and VLB S7-S. During the identification of bacteria in the micro flora, a method using PCR was used. None of the substrates showed a significant advantage over the others.

The study evaluated the Mutant Prevention Concentration (MPC) of Pradofloxacin on three Escherichia coli (E.coli) strains, 2 wildtypes and one first-step gyrA resistant mutant. We also measured the value of AUC (Under the Concentration)/MPC that prevents growth of resistant mutants. It is of importance to reach a concentration above MPC that prevent E.coli from developing resistance against the antibiotic.We used an in vitro kinetic model where we added bacteria? and antibiotic. The culture flask was attached to a pump with an adjustable pump-speed.

Det här examensarbetet har gjorts i samarbete med företaget Simris Alg. Fokus har varit på att förhindra sedimenteringen av företagets kosttillskott av mikroalger. Sedimenteringen har förebyggts med olika förtjockningstillsatser där salt från en makroalg var den tillsats som gav bäst resultat. Tillsatserna blandades direkt i biomassan och utvärderingen gjordes i olika tillfällen under en vecka.Mikrobiologiska tester gjordes för att säkerställa kvalitén på biomassan. De tester som gjordes var för totalantal bakterier, Enterobacteriaceae och Vibrio.
