Antibiotic resistance associated with bacteria in irrigation water : a case study of irrigation ponds in Southern Sweden

The focus of this project was to characterize the occurrence of ESBL-­?producing bacteria in two irrigation water ponds in Southern Sweden. Samples were taken from two ponds nearby each other, from which analyses were made based on levels of community and individual isolates. Community samples were used for attempts for characterization of resistance patterns in irrigation water using the Omnilog PM-­?plate system. The growth of community microbiota in the presence of the following antibiotic substances was assessed; amikacin, gentamicin, kanamycin, penicillin G, ampicillin, piperacillin, trimethoprim, potassium tellurite and ciprofloxacin. Isolates were pure cultured using semi-­?selective media: LB, Rainbow Agar, mEnterococcus, 0.1 TSA and VRBD. A total of 177 isolates were isolated randomly. Each isolate was identified using the Omnilog GENIII-­?system of biochemical characterization. Further, the isolates were tested on Brilliance ESBL-­?agar for their ability to grow. Out of the total number of isolates, 30 were selected, preferably Enterobacteriaceae or Pseudomonas spp., based on their high similarity to library strain during the identification in the Omnilog-­?system. These were further characterized using Etest-­?sticks. Three selected strains were picked for further analyses using exogenous isolation for attempts to simulate horizontal gene transfer, and Omnilog PM-­?panels containing various antibiotics of interest. Selections of samples were chosen for molecular tests targeting plasmid-­?borne resistance genes CTX-­?M1, CTX-­?M2 and SHV. The method for assessing community-­?resistance patterns showed ambiguous data that was difficult to interpret; further optimization is recommended. For all tested PM-­?plates, generally greatest differences between substances were found among wells with the strongest concentration of antibiotic substance. A total of 175 isolates displayed ability to grow on ESBL-­?agar. Etests confirmed ability of isolates to resist many ?-­?lactam antibiotics and many were clinically resistant to certain substances. No plasmids were transferred during exogenous isolation. During molecular tests, a few matches were found for the CTX-­?M1 gene. Isolates analyzed with Omnilog PM-­?plates showed resistance to most compounds tested. The isolates showed greatest resistance toward penicillin G, ampicillin, amikacin, kanamycin and trimethoprim. In the study, it was established that resistance among bacteria was frequently occurring in the irrigation water, and ?-­?lactamase producing bacteria was very common. Extended studies are needed to assess the frequency-­? and occurrence of horizontal gene transfer (HGF) in this environment. Although some potential corresponding data is found, it is at this point not possible to determine whether the resistances are due to antibiotics used in veterinary medicine, human medicine or one additional reason is travel and trade. in irrigation water using the Omnilog PM-­?plate system.

Prehospital smärtbehandling hos patienter med misstänkt höftfraktur : en retrospektiv journalstudie

SummaryPatients with burn injuries involving more than 20 percent of the total body surface area lose a lot of fluid and are in the risk of developing a severe hypovolemia. Fluid resuscitation is a corner stone in burn care and is important for preventingfurthercomplications. The most common resuscitation formula is the Parkland Formula. Hourly urine output is a measure used to evaluate if the fluid given is sufficient enough to maintain a sustainable tissue perfusion. Inhalation injury, abuse of alcohol and drugs are some of the factors that may increase the amountoffluid needed.

Ekosystemansatsen på landskapsnivå

The Convention on Biological Diversity (CBD) promotes the Ecosystem Approach (EA). In this thesis it is analyzed how the EA approach could be applied to regional management of coastal areas in Sweden. The aim of this report is to compare management for preserving biodiversity on a landscape level in two regional coastal areas in Uppsala and Västra Götaland respectively. In Uppsala, one of the plans consists of a previous nature reserve and in Västra Götaland, a Regional landscape strategy has been established. The ecosystem approach is used as a theoretical framework in this thesis.

Implementering och kommunikation av ekologisk h?llbarhet. En fallstudie om utmaningar och strategier i fordonsindustrin

The purpose of the study is to explore the internal implementation and communication of ecological sustainability within an organization and to identify obstacles and challenges that may arise. To address the study's purpose and research questions, a qualitative methodology and semi-structured interviews were used. Respondents were selected from two different units within a large global organization operating in the automotive industry. The study's findings indicate that the organization's sustainability efforts are extensive and integrated across several departments. It is also evident that sustainability initiatives are primarily driven by upper management within the organization, although there is room for lower hierarchical levels to provide some feedback.

Etanol : ett hållbart tankande eller ett kortsiktig tänkande?

Ethanol fuel is a biofuel, which been widely reported in the public debate and on the fuel market the last years. Ethanol is sold as both E85 and as a five percent admixture of all petrol sold in Sweden. Research studies on ethanol fuel often focus on environmental issues surrounding the production and utilization of ethanol as a fuel, and omits the private and business aspects of the subject. The purpose of this study is to illustrate the economics of ethanol as a fuel. How the Swedish market for ethanol is and how it evolved over time and what the future prospects are.

Styrreglage för hållbarhetsstyrning - En fallstudie av hur företags interna styrning aktiverar Levers of Control för att uppfylla hållbarhetskrav

The connection between management control systems for controlling sustainability and a firm's motivation for engaging in sustainability is not completely understood (Arjaliès & Mundy, 2013). The aim of this thesis is to develop a more profound understanding for management control in achieving sustainable companies. To do this, we raise the question: How and to what extent do companies use management control systems to achieve sustainability compliance Simons's Levers of Control (1995) are applied to this question in order to get a consistent and thorough insight of management control systems. Hence, a case study of ABB:s work to achieve material compliance in accordance with EU-regulation was conducted. The findings of the case study reveal that ABB uses the regulations as explicit goals and implement them in sustainability procedures.

Man behöver inte vara officiellt deprimerad Om biblioterapi som biblioteksverksamhet, med Kirklees i England som exempel

The purpose of this thesis is to examine if and how bibliotherapy can be part of ordinary work in Swedish libraries. Questions: what is bibliotherapy and who can work with it? What are the conditions required? What does it mean to people taking part and to libraries? In this study bibliotherapy is delimited to fiction and activities including discussions, excluded are self-help books and the individuals private reading. The study is based on four qualitative interviews with librarian and bibliotherapists in Kirklees, England, partaking in nine bibliotherapeutic sessions and a literary survey, together forming a case-study. Conclusions: There is not a single answer to the question what bibliotherapy is, but if one puts stress on the biblio- part of the word, seeing reading as a normal activity it can be part of library work, whereas the therapy- part should be dealt with by professionals outside libraries.

Svenska miljömål på byggprogrammet?  - Ett sätt att integrera hållbar utveckling i karaktärsämnet

Syftet har varit att undersöka om de Svenska miljömålen kan vara ett sätt att göra hållbar ut­veckling synlig för elever på byggprogrammet. Det har också varit att ta reda på vilka mervärden som kan skapas genom att hållbar utveckling synliggörs genom att miljömål integreras i under­visningen. Delmålen är verklighetsnära och direkt kopplade till byggbranschen, vilket kan med­föra ett ökat engagemang och vilja till att medverka till förändring.Resultatet visar att yrkeslärare, elever och platschefer på byggföretag inte hade kännedom om miljömålen. Svenska miljömål behöver integreras i karaktärsämnena på byggprogrammet för att politiskt fattade beslut om vad som krävs för att vi ska kunna nå hållbar utveckling förmedlas till de elever som skall ut i yrkeslivet, så att de kan komma ut med en hand­lingskompetens som kan leda till förändring. Nästan samtliga var överrens om att det skulle kunna ge mervärden att ha kunskap om hur de i sin vardag kan arbeta med hållbar utveckling.

Planering och exploatering i fjällnära natur

Detta kandidatarbete handlar om planering, exploatering och naturvärden i den svenska fjälen. Syftet med denna uppsats är att studera och analysera hur planering och exploatering i de svenska fjällen påverkar den naturmiljön som finns där. En del av syftet består av att studera hur turismen påverkar planeringen, en annan del är att se hur naturmiljön påverkas av exploateringar. Genom exempel i från den planerade exploateringen av Rödkullen i Åre kommun skall problem och möjligheter som kan uppkomma vid planering och exploatering belysas. En fallstudie har gjorts på Rödkullen i Åre, ett naturområde som inom snar framtid ska exploateras.

Hållbart lärande åt alla. Hur bör skolan vara utformad för att alla individer ska kunna utveckla sina styrkor och bli aktivt deltagande samhällsmedborgare?

Hur bör skolan vara utformad för att alla individer ska kunna utveckla sina styrkor och bli aktivt deltagande samhällsmedborgare? (Sustainable learning for all. How should the educational system be designed in order to allow all individuals to develop their talents and strengths and in becoming actively participating citizens?).

ATT UNDERVISA FÖR HÅLLBAR UTVECKLING : Sex lärares uppfattningar

?Syftet med studien är att undersöka hur ett antal lärare, som har genomgått Grön Flaggs utbildning, uppfattar sitt arbete med handlingskompetens för hållbar utveckling. Frågeställningarna rör hur lärare förhåller sig till olika typer av direkta/indirekta påverkanshandlingar för hållbar utveckling i sin undervisning/verksamhet samt vilka drivkrafter och hinder lärarna uppfattar för att implementera ESD (Education for Sustainable Development).För att besvara våra frågeställningar använde vi oss av en enkät som genomfördes muntligt med sex lärare som arbetar inom de tidiga skolåren. Vi gjorde enkäten muntligt för att få kommentarer/motiveringar till deras svar och på så sätt kunna behandla materialet kvalitativt.Resultatet visade att lärarna uppger sig behandla både direkta (till exempel att källsortera) och indirekta (till exempel att påverka beslutsfattare) påverkanshandlingar, men att de direkta överväger. Många av de drivkrafter och hinder som forskare tidigare har kunnat identifiera framkom även i vår studie, men det framkom även andra, till exempel sådant som har att göra med elevernas engagemang och praktiska förutsättningar.

På vandring mot handling : Utbyte av perspektiv i landskapet

Sustainable Development is often described as a balance between ecological, economical and social aspects. Between these exists a complicated interaction that creates conflicts in the planning of the landscape. We see a growing need for a functional interaction between values and interest and an understanding for different perspectives. Cooperation and dialogue are key ideas with the focus on cooperation rather than the goal. There is a lack of forum for dialogue and cooperation within municipalities where a great knowledge and competence are gathered.

Vägval: kortast, snabbasteller hälsosammast : En försöksmodell i GIS för ruttoptimering och beräknad inhalation av luftföroreningar för cykelrutter

Cycling is one of the most sustainable transport modes available and it is widely promoted inmany urban areas. The health benefits from cycling has shown to be substantial, includingdecreased risks of diseases related to overweight and enhancing brain capacity. However, inurban areas cyclists can temporaly be exposed to high levels of air pollution, resulting inhealth risks as opposed to health benefits.The objective of this thesis is to develop a rasterbased test model in GIS that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four different trips withinSödermalm, Stockholm.The results show that the inhaled particle dose can be greatly reduced, 39% - 58% for three ofthe routes, by choosing the least dose route. One of the most interesting findings is thesubstantial increase of dose when high levels of particles are combined with uphill cycling.The conclusion for the thesis is that a raster-GIS model can be very useful for estimating doseof different air pollution particles and chemicals along cycling routes.
