FCoV och FIP hos svenska katter ? förekomst, hantering i klinikmiljö och information till kattägare
Feline infectious peritonitis (FIP) is a disease that can affect cats and is caused by a feline coronavirus (FCoV). FCoV is spread via the feacal-oral route and many cats are carriers of the virus. Despite that, very few of the carrier cats develop FIP. The explanation of this phenomenon is that the virus has to mutate to be able to cause FIP and in the majority of the carrier cats this mutation never occurs. FIP is very hard to diagnose because the symptoms are diffuse and a completely accurate diagnosis can almost exclusively be established during a postmortem necropsy.
Bioelectromagnetics for improved crop productivity : an introductory review with pilot study of pre-sowing treatment of tomato
Various electromagnetic (EM) treatments has been investigated for their potential in improving crop productivity over the past century. There is today an increasing amount of scientists advocating EM treatments as an organically compatible method for improving plant
growth and yield. However, failure to produce repeatable effects and defining causal mechanisms has made it a study of much controversy and debate. The subject requires indepth
interdisciplinary knowledge, making it inaccessible for the majority of biologists, horticulturists and growers. In this combined literature review and pilot study, these issues are addressed by providing a comprehensive introductory review of the topic plant
bioelectromagnetics and its potential horticultural usability.
Virala orsaker till abort hos hund
Virala orsaker till reproduktionsstörningar så som abort, resorption av foster och dödfödda valpar är hos hundar ofullständigt kartlagda. Herpesvirus är det agens som har studerats mest och är även ett välkänt abortagens på andra djurslag, däribland häst. Hundens herpesvirus (CHV-1) orsakar hos vuxna individer i regel endast milda respiratoriska symptom. Hos dräktiga djur kan viruset ge upphov till förlust av valpar och även orsaka en kraftig och dödlig infektion hos neonatala valpar. Precis som många andra herpesvirus kan CHV-1 ge upphov till en latent infektion som kan reaktiveras vid stress.
Betydelsen av anlagda våtmarkers area och ålder för förekomst av sjöfågel inom Linköpings kommun
The aim of this study was to examine what impact restored and constructed pounds and wetlands have on waterfowls in the area of Linköping. The birdlife in five constructed wetlands werechosen to investigate if specific factors like age, size and vegetation affected the avian diversity in wetlands. Also, extra focus has been given to the threatened Horned Grebe (Podiceps Auritus), breeding in the studied area. The results showed that the number of species as well as individuals of waterfowl and Horned Grebe changed over time in what might be a result of succession in the wetlands. Comparing the number of birds to the size of the wetlands showed a clear correlation. Larger areas inhabited greater numbers of species and individuals.
Från svartvit till färg : en studie av färg i Michelangelo Antonionis film Den röda öknen
Michelangelo Antonioni (1912-2007) belonged to a generation of filmmakers that breathed new life into cinematic expression in the annals of modern-day European film history. By employing his background as a documentary filmmaker, Antonioni used these skills to help establish his own particular style. There was a distinct evolution of style which progressed during his triology L´Avventura, La Notte and L´Eclisse, 1959-1962. This theises presents a comperative study between his earlier films in black and white and his first color film - Il deserto roso, from 1964. By observing color in relation to narrative, dialouge, acting and elements of mise-en-scène, I suggest different answers than those previously discussed among critics concerning this interrelationship.
?It´s still real to me damn it!? En retorikanalys av amerikansk wrestling
Professional wrestling has been around for over a hundred years. Its origin can be traced back to immigrants in the 1800´s whos collar and elbow style of wrestling became popular. Soon it found its ways into the carnivals traveling the country and there it became the wrestling that we know today. Two men, screaming and bragging how good and strong they are, trying to convince its audience that it shall pay to see the fight.The purpose of this essay is to look at two of wrestling?s biggest names in Hulk Hogan and Ric Flair from a rhetorical standpoint and see what they do to convince their audience to buy their matches.
Retrospektiv studie av porcint circovirus typ 2 och postweaning multisystemic wasting syndrome i Sverige :
Porcine circovirus type 2 (PCV2) is a common virus present in most parts of the world.
PCV2 has been pointed out as the major causative agent to post weaning multisystemic
wasting syndrome (PMWS) that affects pigs after weaning. The clinical symptoms of PMWS
are impaired growth, diarrhoea, respiratory problems and increased mortality. At autopsy
enlarged lymph nodes with depletion of lymphocytes are commonly found.
Since 1991 PMWS has spread all over the world and was first described among Swedish pigs
in 2003. Although PCV2 is widespread, only some pigs develop PCV2-related diseases.
Why this is and what other factors that are required in order for the disease to develop is yet
unknown. The main theories involve other infections, for example PRRS, and management
issues but also genetic differences between pigs and/or virus strains have been suggested.
Skadlig kod och sårbarheter i Windows : En studie i virusens historia och nutidens olika säkerhetsrisker
I dag kan man oftast läsa om olika säkerhetshot och risker en datoranvändare måste tänka på för att inte ge någon utomstående möjlighet att komma åt känslig och/eller privat information. Här talas det om nya virus och nya typer av trojaner som sprids som epidemier över Internet, och i bland handlar det om ett spionprogram som följer med en nedladdad fil. Det är svårt att hålla reda på alla typer av skadlig kod som nämns fast med ökad förståelse ökar också chanserna för att klara sig från smitta. Det har visat sig att utvecklingen av skadlig kod är lika stark som den inom kommersiella mjukvaror. Från persondatorns uppkomst i början av 80-talet och fram till i dag, har utveckling skett i alla områden av den skadliga kod det handlar om strategi, syfte och framförallt ren kodkomplexitet.Dagens ledande leverantör av operativsystem och webbläsare, Microsoft, lovar allt mer sofistikerade säkerhetslösningar varje gång en ny version av ett program släpps.
Development of a real-time RT-PCR for quantification of bovine TLR4 mRNA and evaluation of its use during a BRSV vaccine challenge
The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.

Analysis of CD4+ and CD8+ T-lymphocytes : A comparison between EPICS XL and Celldyn Sapphire
Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.
Prevalens och genetisk karaktärisering av afrikansk svinpestvirus i vektorer och tamsvin i Uganda
African swine fever, ASF, was first described 1921, in Kenya. The virus has thereafter spread through many African countries as well as in Europe, Asia, South- and Central America. The virus is spread via three different cycles, of
which one is sylvatic and includes warthogs and soft ticks. The other two are between domestic pigs and the one most common one is caused by humans, who not always realize the seriousness of precautions. The infection manifests as
hemorrhagic fever, but can also be more or less unnoticed.
The aim of this study was to use molecular tools to detect and partly genetically characterize ASFV both in soft ticks and in serum from domestic pigs in Uganda.
Comparing viruses detected in ticks with those detected in domestic pigs I also wanted to investigate possible links between the sylvatic and domestic cycle.
Kunskapso?verfo?ring inom franchisena?tverk : En studie av utveckling och o?verfo?ring av kunskap inom franchisena?tverk
This case study has been conducted within the Swedish fitness chain World Class to explore the opportunities for knowledge development and transfers within franchise networks. We have interviewed the product manager at the World Class headquarter, the owner of a franchise club and a local product manager from the same facility. Our finding indicates that various forms of knowledge transfer occur within the World Class network, particularly in product development and sales. The transfer occurs within the framework set by World Class with regularly scheduled meetings. In addition informal networks provide other means of knowledge exchange between some units.
Vårtor på mjölkkornas spenar :
The reason why I choose the subject ?Warts on teats of Dairy Cows? was because the
herd I work with has big problems with skin-complaint on teats and udder.
So I found it interesting to try to find the reason why the cows look like they do and
even to find a way to relieve the trouble.
The examine work included both a literature research, an experimental test,
concerning a comparison of different teat sprays and also an inquiry-research about
the occurrence of warts in practical herds in order to collect as much facts as possible.
Three companies, selling different types of teat disinfectants, were willing to sponsor
the teat dipping experiment. The aim of the experiment was to see if any special
disinfectant had more pronounced healing effects on teat warts. The date for the
experiment was 18th December 2004 to 22nd January 2005, which was going to be 5
weeks.The experiment was carried out in the herd of Ola and Eskil Carlsson in
Fjärlöv, Hässleholm.
The three compared teat spray chemicals were; Nova Viri Sun, Nardosept, and
BlockadeTM. These chemicals were compared to one control group, which teats were
treated with the ordinary chemical normally used in the herd, i.e.
