Enkel intravenös administrering av trimetoprim-sulfadiazin hos neonatala föl : farmakokinetik samt känslighet hos gramnegativa bakterier från föl med septikemi
The retrospective part of this study evaluates the susceptibility patterns of bacteria isolated from blood in critically ill foals in Sweden. The most commonly obtained bacteria were Actinobacillus spp. (38 %) and Escherichia coli (27 %). Trimethoprim-sulphonamide (TMS) had good efficacy against most gram negative bacteria with the exception of Klebsiella spp. Among 17 Escherichia coli isolates 94 % were susceptible to trimethoprim-sulphonamide whereas all 24 isolates of Actinobacillus spp.
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.
Magnetfält alstrade kring nätstationer i samband med lokaldistribution av elkraft : Magnetic fields generated by electrical substations during distribution of electric power
Abstract: This report covers primarily the work of documenting electromagnetic fields generated by one of the later parts in the electrical power distribution chain: The electrical substation, wherein 10 kV is transformed to 400 V for use by private consumers. Thus it is one of the most widespread and frequently occurring parts in the Swedish power grid and of particular interest, as electrical substations are found everywhere in populated areas, often in close vicinity to people and animals.The report deals with a number of formulated questions and/or hypothesis? stated at the onset of the work undertaken, theory that is relevant for the topics the report covers, the details of the field work undertaken and the following analysis of the readings, which in term provide answers for the questions stated in the beginning. It also covers what is the currently known short term and long term risks associated with electromagnetic fields in the power frequent spectrum and of varying intensity in the vicinity of humans.The analysis also provides recommendations and identifies several points to carefully consider when planning for new installations or replacements of some parts of existing installations.For enhanced reading comprehension there is, aside from sections with pictures and attached explanatory texts and templates, several graphs, one-line diagram and maps of the power grid among the appendixes to the rapport..
Reduktion av organiskt material med MIEX®
Uppsala- och Stockholmsregionerna använder Mälaren och dess tillflöden som dricksvattenkällor. I Mälaren varierar halten organiskt kol från år till år och kan medföra problem såsom oönskad lukt, smak och färg vid dricksvattenrening. Det kan även vara problem med avseende på bildning av desinfektionsbiprodukter (DPB) och transport av toxiska ämnen med dricksvattnet. I takt med den globala uppvärmningen kan dessutom halten av organiskt kol i Mälarens ytvatten och dess tillflöden öka. Det medför att halten av organiskt material även skulle öka i vattenverkens råvatten och det skulle i sin tur uppstå svårigheter att hålla dagens gränsvärden.
Temperaturens, kadaverålderns och radiopulssekvensens betydelse för bildkvaliteten vid magnetresonanstomografi av tarsus hos häst
Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.
Variationer i normal språklig förmåga hos vuxna jämfört med neural aktivitet
Since the brain is an important prerequisite for human language there is a great interest to gain more knowledge about healthy brain activity during language mediated communication. This study examines variations in high level language ability relating to demographic factors like gender and age and relates language ability to neural activity.Eighteen individuals in ages between 22 and 64 were included and divided into groups in relation to gender and age. The material used to assess language ability was derived from Testbatteri för Bedömning av Subtila Språkstörningar (Laakso, Brunnegård, Hartelius & Ahlsén, 2000), Swedish Lexical Decision Test (Almkvist, Adveen, Henning & Tallberg, 2007) and a reading test (Högskoleprovet). The results were correlated with measured brain activity using functional Magnetic Resonance Imaging (fMRI) and language paradigms. ANOVA was applied to discover possible demographic variances in language ability as well as in brain activity.The results showed no significant differences in language ability.
Induktiv provning av ferritiskt rostfritt stå
The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.
Påverkar behandling med magnettäcke beteendet hos friska hästar?
Magneter har använts långt tillbaka i tiden för att behandla olika åkommor. Det senaste årtiondet har de fått ett uppsving som en alternativmedicinsk metod. De påstås ha olika medicinska effekter så som att ge ökat blodföde och verka smärtlindande och avslappnande på ömma muskler. Syftet med den här studien var att studera huruvida hästtäcken med 120 stycken insydda permanenta magneter (à 900 gauss) har någon effekt på beteenden hos hästarna vilka tyder på en ökad avslappning. Sju normala, friska hästar inkluderades i en prospektiv, randomiserad, blindad, placebokontrollerad cross-over studie.
Konstruktion av säkerhetslagerför svänghjul
This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.
Avvikande lateralisering av motortrösklar hos vuxna som stammar : En TMS-studie
Stamning är en komplex motorisk talstörning, vars neurologisk bakgrund fortfarande inte är klarlagd. En växande mängd studier ger dock stöd för att stamning kan vara orsakat av strukturella avvikelser i den vänstra hemisfären. En studie (Sommer et al., 2003) som använde transkraniell magnetstimulering (TMS) för att undersöka kortikal inhibition hos personer som stammar (PsS) fann som ett bi-fynd att den stammande gruppen hade signifikant högre motortrösklar (MT) för vänster hemisfärs handmotorarea, det vill säga att det krävdes starkare stimulering för att väcka en muskelrespons i den kontralaterala handen. Resultat har dock inte uppmärksammats av senare forskning, och behöver verifieras. Den aktuella studien syftade till att undersöka om PsS tenderar att ha förhöjda MT, samt om det finns avvikande hemisfärsskilnader i MT hos PsS.
Bärarskap av meticillinresistent Staphylococcus pseudintermedius (MRSP) hos svenska hundar :
During the last years, meticillin resistant Staphylococcus pseudintermedius (MRSP) have caused an increasing number of infections in Swedish dogs. MRSP is resistant against a majority of the antimicrobials available for dogs in Sweden, making it difficult to treat the infection. Our knowledge of the bacterium is limited, making it hard to handle infected dogs in a proper way. The aim of this study was to investigate for how long time dogs, who have an infection caused by MRSP, become carriers of the bacterium. Other factors like treatment with antimicrobials, the correlation between clinical symptoms and carriage, common diagnoses and institutionalization where also looked upon.
Förekomst av penicillinkänslighet hos blododlingsisolat av Staphylococcus aureus
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.

Användbarheten av två modeller i två olika företag, en studie av lean production : Fallstudier vid SKF Couplings systems och AQ Parkoprint
This study is about to see whether the two models representing the strategies of lean production is to use and apply in different companies. The models are structured in two different ways in which one of them is checking the softer elements of lean production in the form of leadership and strategies. This model is called Lesat and is based on interviewquestions. The second model, called "learning to see" is about identifying flows. This, together shall then give an idea of how mature companies are when it comes to a whole in the concept of lean production, and susceptibility to use these models to their respective companies. The study is conducted in two companies, SKF couplings systems and AQ parkoprint.
