Prevalence of toxin-producing strains and antimicrobial resistance in isolates of Staphylococcus hyicus from pigs with exudative epidermitis and from healthy pigs
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.
Ackumulation av CO2 och CH4 i istäckta boreala sjöar : Hur förändras ackumulationen i sjöar påverkade av avverkning jämfört med referenssjöar?
The aim of this report was to quantify the accumulation of carbon dioxide (CO2) and methane (CH4) in ice-covered lakes in winter (October-March) during three consecutive years, and to assess whether the concentrations of DIC and CH4, as well as the ratio DIC:CH4 differs between years and between lakes affected by clearcutting and untreated reference lakes. Water- and gas samples were collected from four boreal lakes (two affected by clearcutting and two untreated reference lakes) located in Västerbottens inland in spring. The lakes were found to accumulate on average 91, 55, and 84 mgCm-2d-1 during winters 2012-2013, 2013-2014, and 2014-2015, mostly originating from CO2. The concentrations of DIC (autumn and spring) were higher in the affected clear-cut lakes compared to reference lakes for all years, including the reference year (2012-2013) before clear-cutting. No such difference was found for CH4 or the ratio DIC:CH4.
Användning av geografiskt informationssystem (GIS) vid studier av nötkreatur i landskapet - en pilotstudie :
The Animal Protection Agency was in 2006, commissioned by the Government to: Evaluate how free range animals in the winter, can be kept and managed with special emphasis to animal welfare. The Animal Protection Agency was closed later in 2006 and the commission moved to the Swedish Board of Agriculture. The keeping of free range out wintered cattle, certain basic requirement are needed: by regulation, cattle should have access to a lying hall or other building that gives protection against aversive weather and wind and should offer a dry and clean lying area. There is a possibility for farmers that get an exemption from this regulation. But cases regarding farms which have had difficulties for this exemption has led to a discussion about if the animals can get the same protection in the nature which is comparable to a lying- hall.
Läxhjälpen: tidsstjälare eller en resurs för elever att nå målen? : elevers, lärares och rektors uppfattning av läxhjälpen på en gymnasieskola i Stockholm
For most pupils homework is a natural part of school and their education and there are several providers of homework assistance: the pupil's parents, sibblings, friends, Internet forums, hired private tutoring, non-profit organisations and at times even the pupil's school. This study has investigated the use of the school-based homework assistance programme at the Upper Secondary School of Psychology in Stockholm and why the programme is not more frequently used by its pupils. The school offers homework assistance two hours each Thursday afternoon, with at least two teachers being present to tender for the school's 127 pupils. The cost of the programme has been estimated to approximately 12 500 Swedish kronor per week. Through the main use of a questionnaire given to both the school's students and teachers, as well as an interview with the school's headmaster, this study will show that despite receiving the opportunity few pupils take part of the programme on a regular basis.
Utformning och drift av ventilationen i en förskola. En jämförelse mellan CAV och VAV-system.
Dagens samhälle är i behov och strävar efter att få ner energianvändningen. Inte minsti byggsektorn där nyare teknik och smarta innovationer gör att vi kan sänka vårenergiförbrukning och då även få ner våra energikostnader. Ett sätt att reducera dessabåda faktorer är att byta ut gamla ventilationslösningar mot nya mer energieffektivasystem. Att välja en viss typ ventilationssystem är däremot inte alltid ett enkelt beslutdå det finns ett flertal olika principer av system man kan utgå ifrån för att ventilera enlokal och skapa ett bra inneklimat. De enklaste ventilationssystemen ger ett konstantluftflöde medans man med mer avancerade system kan använda sig av varierandeluftflöden för att förse en lokal med frisk luft utefter det behov som finns.Denna rapport har i sin helhet tittat på de förutsättningar som finns då man utformarett ventilationssystem för en förskola.
Inventory and evaluation of Nairobi Animal Orphanage : focusing on routines and feeding, black-backed jackal, lion and patas monkey
This BSc thesis is an introductory step to the collaboration between the Swedish zoo Skansen and Kenya Wildlife Service (KWS). It constitutes of an inventory of the Nairobi Animal Orphanage (AO), a facility that cares for injured and abandoned wildlife species in Kenya. Through the cooperation with Skansen, the KWS will improve their management of the AO. The aim of the inventory and BSc theses is to evaluate the management of black-backed jackal (Canis mesomelas), lion (Panthera leo) and patas monkey (Erythrocebus patas) regarding their biological needs. The general enclosures, routines and feeding at the AO are also evaluated since they have a great influence on the management of captive animals.
Skillnader mellan länsstyrelser ? takhöjd för häst
To ensure that animals are treated well and kept in environments fitted for them, Sweden has animal welfare legislation. One of the requirements in the legislation is that horses are kept in spaces that has a ceiling height that measures at least 1,5 * the height at the withers of the horse, but always a minimum of 2,2 m. But a minor derivation can be accepted from these measurements if certain criteria are fulfilled. If the ceiling height is to low the ventilation in the stable can be negatively affected. It can also affect the posture of the horse and may increase the risk of the horse being injured.
Clear-cut and substrate characteristics important for the occurrence of the beetle Upis ceramboides
Disturbances, such as fire and wind, are important for saproxylic beetles (= beetles depending on decaying wood) to gain substrate in boreal forests. Clear-cutting is an example of a man-made disturbance. Measures such as prescribed burning have been made to resemble natural disturbances. The aim of this study was to see which clear-cut characteristics are important for the occurrence of the saproxylic beetle Upis ceramboides.
This is a species favored by open habitats and is said to respond positively to forest fires. The distribution area in Sweden for this species has decreased during the last two centuries and I wanted to see if there were differences between clear-cuts in Hälsingland, where it is very
rare and decreasing, and Norrbotten where this study was conducted.

Uppsatsens titel: Utformning av ett balanserat styrkort - En fallstudie på Lindabs svenska filialerKurs: Examensarbete, Civilekonomexamen, Controller, 30hp (4FE03E)Lärosäte: Ekonomihögskolan vid Linnéuniversitetet, VäxjöFörfattare: Martin Andersson och Stefan KesakHandledare: Elin Funck Examinator: Lars-Göran AidemarkDatum: 2012-05-26Nyckelord: Balanserat styrkort, Benchmarking, Prestationsmätning, Strategi, Försäljning, Filialverksamhet Bakgrund: Lindab är en internationell ventilations- och byggkoncern som är uppdelad i de tre affärsområdena Ventilation, Building Components och Building Systems. Försäljning och distribution av Lindabs produkter sker främst via egna filialer. Studien fokuserar på de svenska filialerna och utgår från Lindabs önskemål om att få hjälp med att förbättra sin prestationsmätning samt öka jämförbarheten mellan filialerna.Syfte: Uppsatsen syftar till att utforma ett balanserat styrkort för Lindabs försäljnings- och distributionsfilialer i Sverige för att ge förutsättningar för en bättre kontroll och styrning av deras prestationer och öka jämförbarheten mellan filialerna.Metod: Vi har genomfört en fallstudie på Lindabs svenska filialer med en abduktiv forskningsansats. Det empiriska materialet grundar sig på intervjuer, filialbesök, samt externt och internt material.Resultat och slutsats: Vi har utformat ett balanserat styrkort som möjliggör bättre kontroll och styrning av filialernas prestationer genom att Lindabs vision och strategier har brutits ner i strategiskt viktiga mått i de olika perspektiven. Vårt styrkort skapar dessutom en balans mellan kortsiktiga och långsiktiga målsättningar, externa och interna prestationsperspektiv, finansiella och icke-finansiella mått samt mellan utfallsmått och drivande mått.
Hur små företag kan uppnå lönsamhet på en konkurrensutsatt marknad
The interest for children´s clothing has increased in society. More and more children are born and parents are older when they have children. Education has become a natural feature in most people´s life, just as both parents often work today. The households have therefore better economy and thus greater consumption opportunities. Parents are, in greater extent, looking for personal and different clothing with focus on quality and, to some extent, exclusivity rather than just a cheap and functional garment.
Hallsta Pappersbruks virkesförsörjning
Competition of spruce fiber raw materials has increased dramatically in the last few years, leading to the fact that transportation costs in the current situation represents a much larger share of the total raw material cost. The Holmen-owned pulp industry Hallsta Paper Mill's location on the coast also constitutes a problem, because of the lack of raw material, which is much larger there, than for a pulp mill located in the hinterland. For a coastal industry it?s therefore natural to import much of the raw material by boat or to buy it from the timber terminals, in order to maintain good profitability. The purpose of this study was to analyze how the size of Hallsta Paper Mill timber supply area, without competition, with competition and with terminal use, affects the company ?s transport costs.
100 % svenskt foder till mjölkkor :
As for today, a large quantity of protein feeds is imported from other countries to be used in
the Swedish dairy production. The main import is soya from Brazil. The soya-production in
Brazil results in negative consequences for the natural environment in the area, and the long
transport of the feeds requires a lot of energy. The organic dairy production in Sweden is,
with the highest probability going to be forced to use 100 % organic feed to the cows in the
year 2005, due to new EU-rules. These are some of the causes why there are reasons to look
closer at the possibilities to feed Swedish cows with only Swedish feeds.
In this study, I have looked at the KRAV-rules for organic feeding, where the goal is feeding
with only KRAV-approved feeds.
På väg. En undersökning av en svensk stadsmotorväg
The purpose of this essay is to examine one of Sweden's oldest motorways in cityenvironment. The researched section is motorway E20 east of Gothenburg. Olskroksmotetin the west and Jonsered junction in the east, a distance of about 11 km. The mainquestion was, can maintenance of areas and objects related to the motorway give greatermeaning to a system that currently lacks historical connection?The survey was partly an archival study and partly a physical examination of themotorway and its appearance today.The road through Säveedalen from Gothenburg has a long history that begins with theriver and its valley as transport routes.
Kommunal krishanteringsförmåga : Uppsala kommuns beredskap inför en eventuell naturkatastrof
De senaste åren har det skett en nedprioritering av risk- och krisföreberedande arbete på kommunal nivå, främst gällande naturkatastrofer. En av anledningarna till detta är att de kommunala medlen prioriteras mot andra saker som exempelvis skola, vård och omsorg.Syftet med uppsatsen är att undersöka lärdomar och förmåga rörande hanteringen av naturkatastrofer på olika myndighetsnivåer i Sverige. Lärdomar studeras utifrån ett verkligt exempel: skogsbranden i Västmanland sommaren 2014. Huvudfokus för uppsatsen är att studera Uppsala kommuns förmåga att hantera en eventuell framtida naturkatastrof.För att undersöka syftet används två teoretiska modeller: Framgångsfaktorer för krishantering samt DROP-modellen. Framgångsfaktorerna används sedan för att se om lärdomar har inhämtats ur skogsbrandskatastrofen.
"Självet" och att bli sig "själv" : Sören Kierkegaards process och reflektion sedd med den positivistiska och negativistiska metoden
What is the?self? and to become ?one-self?? To resolve this questions possibility I´ve been using the philosopher Søren Kierkegaard metaphysic paradoxes. This essay about the ?self? shows the reader the difference between describing a transcendent and immanent phenomenon and if it´s possible to become or to not become ourselves. The process is a key of the ?self? which Kierkegaard explains the ?self? in and for it-self.
