Antibiotikaresistens hos bakterier isolerade från friska hundar i Sverige : indikatorbakterier E. coli & Enterococcus spp samt Staphylococcus spp isolerade från hud
Objective: To determine the frequency of antimicrobial resistance in bacteria from healthy Swedish dogs and whether they are carriers of methicillinresistant Staphylococcus aureus (MRSA).
Material: Samples from skin from the perineal region and from faeces collected in the anus with cottonswab (Copan) from 299 healthy Swedish dogs. Samples were collected at dog exhibitions.
Method: Specimens were submitted for bacterial culture where bacteria (Escherichia coli, enterococci and staphylococci) were isolated and identified by current methods. Antimicrobial susceptibility testing was performed with a microdilution method where MIC-values were determined. Staphylococci with high degree of resistance were tested for presence of mecA-gene by PCR.
The effect of domestication on insect resistance in cotton : bioassays with the insect herbivores Spodoptera littoralis and Agriotes spp.
A plant's defensive ability against herbivore attack can be influenced by many different factors, one of them being domestication. During human selection to improve the yield of plants, the resistance against herbivore attack can have been lowered, due to a trade-off for use of resources between these traits in the plants.
In this thesis I investigated the effect of domestication on resistance against herbivorous insects in cotton plants. I used different varieties and species of wild and domesticated cotton in three different experiments. A feeding assay was conducted, the mortality, development
time and pupal weight of larvae of the Egyptian cotton leaf worm Spodoptera littoralis was studied. In a second experiment the preference of the root-feeding beetle Agriotes spp.
Organisationsförändring ? hot eller utmaning
Working life changes, just like the rest of today?s society, at an accelerated pace. It is through changes and challenges that human beings develop, personally and professionally. Changes are often met by resistance. The purpose of this study is to see how different factors influence individuals? experiences of change.
Equine metabolic syndrome
Obese horses with insulin resistance are often also afflicted with laminitis. Horses with these symptoms are given the diagnosis equine metabolic syndrome (EMS). Signs of insulin resistance are excessive accumulation of adipose tissue on the neck, around the withers and on the dorsal area of the hindquarters. Insulin resistance means that the function of insulin is defective and does not stimulate glucose uptake by the cells in the body in the correct way. This will result in an increased insulin release.
Cystisk endometriehyperplasi/pyometra-komplexet hos hund : orsaker och patogenes
Virulent strains of Staphylococcus hyicus produce exfoliative toxins and cause a potentially fatal skin disease in piglets known as exudative epidermitis. Vaccines and antimicrobials are used to control the disease. Antimicrobial resistance and the prevalence of several different toxin genes and toxigenic strains make it problematic. The aim of this literature study was to identify potential differences between countries and between healthy and diseased pigs regarding antimicrobial resistance and toxin-producing strains. Great differences could influence vaccine production, treatment strategies and surveillance programs.
Intelligenta Switchar
This master thesis has been carried out on behalf of Stoneridge Electronics AB and is an investigation ofhow intelligent switches can replace the traditionally used direct controlled switches. The concept ofintelligent switches is that the switches contain electronic identification components which, by connectingthem to a network, give the same function independent of the location of the switch. This infers anincreased flexibility and configurability which can be a great advantage in development, production andcustomization in the commercial vehicle industry. Especially in the current situation when commercialvehicle manufacturers provides more and more functions and dashboard configurations.LIN (Local Interconnect Network) is a network protocol introduced in 1999. It is a simpler and lower costcomplement to CAN (Controller Area Network) and is adapted for applications where the demands forbandwidth are lower, for example reading sensors and switchers.
Konst Offentlighet Motstånd Om konst som motstånd i den urbana offentligheten - En fallstudie av konstprojektet (O)önskad samhällsförbättring
This thesis is a cultural theoretical case study of the art project (O)önskad samhällsförbättring.Via an analysis of the project, that is based on theories of power, resistance and contemporaryurban development, it examines the construction of urban space, its impact on public art including the ability of art to initiate evolvement of the urban public space.The last decades art has plaid an important role in what is called the creative city; to become attractive nodal points of the global economy, larger cities increasingly invest in art,culture and creative industry. Simultaneously the urban public space is limited to activitiesand expressions of art that are presumed to create economic growth. This introduces animpression of what is allowed and what is not allowed, possible and not possible, wished andnot wished which, as a consequence, evolves the public space. The events during the artproject and the reactions that followed enlightened these limitations. This tells a story, not only about the structuring process of the local urban space, but also important changes that are created as a simultaneous effect at different levels in society, as well locally as globally.
Resistenta rapsbaggar :
Oilseed rape crops are an important in southern Sweden because of the high intensity
of wheat growing. Pollen beetles are the most important pest in oilseed rape and
causes often economic losses. Therefore it?s of great importance that we can control
the population density, e g by using insecticides if necessary, to avoid mayor yield
losses.
In year 2000 pollen beetles were numerous in the province of Östergötland. The
farmers sprayed with insecticides several times, but with low effects on the beetles.
Field trials and laboratory experiments showed that pollen beetles had developed
resistance against pyrethroids.
Molecular analysis of insecticide resistance in pollen beetle (Meligethes aeneus)
The escalating usage of pyrethroids has resulted in an increased awareness about resistance towards pyrethroids in insects. Pyrethroids inhibit voltage-sensitive sodium channels (VSSC) in nerve cell membranes and are composed of synthetic molecules based on pyrethrins present in pyrethrum extracts from Chrysanthemum species. VSSC are transmembrane proteins that are important for electric signalling over the membrane in insects. Mutations in the gene encoding the sodium channel have proved to be a common reason for resistance against pyrethroids. Pyrethroid resistance among pollen beetles is spread all over Sweden and also abroad and is increasing.
Hydrofob interaktion : en resurs för att reducera antibiotikaanvändningen
It is important to know what is normal in the wound healing process in order to determine what happens when a wound does not heal as expected. If the amount of bacteria in the wound gets too large the body will not be able to defend itself and it becomes an infection. Colonization and infection are common elements in wound management and it is often the veterinary nurse role to deal with wounds in a proper manner. Antibiotics are drugs that either kill or inhibit the multiplication of bacteria or fungi, and have been in veterinary medicine for approximately 60 years. Very few new antibiotics are introduced and increased resistance is a major problem that requires everyone to take responsibility to reduce the use of it.
Dietrich Bonhoeffer som motståndsman och Svenska kyrkan. Ett påbörjande av en kartläggning av deras kontakter och motståndsrörelsen i allmänhet
The overall purpose of the essay is to initiate a survey and highlight, on the basis of sufficiently material, the dealings between Dietrich Bonhoeffer as a member of the resistance and the Swedish Church and/or its representatives. The purpose of the survey is to structure Dietrich Bonhoeffers activities in Sweden and highlight its implications.The following research questions have been used:1: What was Dietrich Bonhoeffer doing in Sweden and what persons did he meet?2: What was the role of the Swedish Church during the Second World War? 3: What was the impact of Dietrich Bonhoeffers visits to Sweden?In conclusion, this study of the contacts between Dietrich Bonhoeffer and the Swedish Church has shown: Dietrich Bonhoeffer was in Sweden on two occasions. He met representatives of the Swedish Church, which was engaged in issues related to ecumenism, resistance and peacework. Although the persons he met were representatives of the Swedish Church they sometimes acted as individuals with a Christian philosophy.
Motstånd till förändring
The aim of this study is to compare attitudes to change among innovation and economics students and teachers at one of the universities in Sweden.Data about students? and teachers? attitudes to change was gathered using a survey.Keeping in mind that knowledge can lower ones resistance this study is based on a hypothesis that individuals from the innovations program have a lower resistance to change. The study is also based on earlier research in regards to comparisons between students and teachers.The results of the study show that teachers have less resistance to change than students. Individuals in the innovation program are however less resistant to change than individuals in the economics program.One can discuss whether or not results of the study show that the hypothesis is correct.The difference between individuals in the economics- and the innovation program are statistically significant and has moderate effects in reality. The differences between teachers and students are statistically significant but only have a small effect.It is however a starting-point for future studies that will possibly explore the subject more profoundly..
Frihetens regim : Nyliberal subjektivering hos Foucault
This paper focuses on the role freedom plays in Michel Foucault?s analyze of liberal and particularely neoliberal governmentalities. From his perspective, neoliberalism operates through the strategic production of entrepreneural subjectivity and distribution of self-governing. Here autonomy is central for governing, which raises questions about what freedom can mean at all in Foucault, and how resistance can be possible. Through Foucault?s thinking on liberal freedom, we can gain a better understanding of his philosophy on subjectivation and resistance..
Utveckling av Mätmetoder för Färdmotstånd
The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.
Antibiotikaresistens - djursjukskötarens roll i att förhindra spridningen
There are several different kinds of bacteria that has developed resistance against the antibiotic agents used in todays medicine. Most of them has evolved from the human health care but several of them has gone over to also cause problems in the animal health care. They often occur as nosocomial infections and the greatest risk of exposure to them is during health care. Since infections with a resistant bacterium can be difficult to treat, it is desirable to prevent this spread, especially since an animal treated in a hospital often is more susceptible to infection, due to their primary condition. In Sweden the current resistance situation is good and is yearly monitored by the Swedish Veterinary Antimicrobial Resistance Monitoring (SVARM) programme.
