Förekomst av agens i kattsnuvekomplexet på ett svenskt katthem

Conjunctival swabs from 12 cats in a Swedish animal shelter were analyzed by real-time PCR for FHV-1, Mycoplasma felis and chlamydiae. The purpose of this study was to see whether and to what extent these agents can be detected and if they were detected from cats housed in quarantine or in the adoption department. Samples were first taken upon arrival at the quarantine and then a second sample was taken two weeks after moving to the adoption department, or upon presentation of signs of disease. The cats spent the quarantine period in two separate quarantines: five in a new quarantine (quarantine A) and seven in a room in the old shelter (quarantine B). The difference between these quarantines was that in B the cats were often mixed together ant the hygiene routines were not as good as in quarantine A.

Webbsida och demo-EP

Syftet med detta kandidatarbete var att sätta samman ett promopaket bestående av en webbsida och en demo-EP med passande grafisk design. EP:n har tre spår elektroakustisk instrumentalmusik av skiftande karaktär, samt ett stilrent men ändå suggestivt omslag. Webbsidan är till för att presentera mig själv och mitt arbete (inte bara musik), och är byggd med hjälp av HTML, PHP, CSS och MySQL..

Investigation of the reward cycle associated with play behaviour in lambs

The aim of this study was to investigate if behaviour, ear positions and cortisol in lamb which were given access to play followed the different phases of the reward cycle of anticipation, consumption and relaxation. The study was done on 8 Dorset and 12 Dorset x Fine Wool uncastrated male lambs with an average age of 10 weeks. The lambs were housed pairwise in litter pens (2 x 3 m). Pairs of lambs were taken to a play arena (5.9 x 5.5 m) three times a week during five weeks (first week for learning). They were then first kept in a holding pen where they could look into the play arena for 5 minutes and thereafter released for 20 minutes in the play arena which had a ball, two chains and a tunnel.

Validering av metoder för analys av Cu, Fe och Na i processvatten med AAS-grafitugn

Södra Cell Mörrum is one of the five paper pulp plants that are included in Södra Cell, and the paper pulp that is produced here is not only sold to Swedish paper mills. Most of the paper pulp is exported to different countries in Europe. In the manufacturing process the plant needs different kind of process water and there are guideline values for how much copper, iron and sodium this water is allowed to contain. Analyzes of this water is in the current situation done with an atomic absorption spectrometric instrument (AAS-instrument) with a flame. Measurements done with flame-AAS of samples that have concentrations near the guideline values for copper, iron and sodium, are not reliable. The reason for not being reliable is that the quantitation limits of these metals are higher than the limit values.

Crowdsourcing : Vad motiverar studenter till att delta?

AbstractTitle: Crowdsourcing ? What motivates students to participate? Level: Bachelor thesis, 15 credits. Authors: Sara O?ra?s & Tomas PetterssonSupervisor: Martin AmsteusDate: June 2013 Introduction: More and more companies realize the importance of using external resources to generate the best possible developmental outcomes for their particular business. The probability that all the smart people work for your company is not very big, therefore it is wise to use the public and take advantage knowledge, ideas and expertise of the public. Crowdsourcing is when a group of people is challenged to solve a problem for a company or to generate solutions and innovative ideas in exchange for compensation. A key issue is the question of what motivates individuals to participate in crowdsourcing.

Organic acids in liquid feed for pigs - palatability and feed intake

Fermented liquid feed is well known for its health promoting effects on piglets. High levels of lactic acid are desired in the feed together with low levels of acetic acid and certain biogenic amines. Limits for acetic acid have been suggested to be 30-40 mmol/kg to avoid a decreased palatability of the feed; however, few studies have been performed. The purpose of this trial was therefore to examine which levels of lactic acid and acetic acid that can be accepted in a fermented feed without affecting the feed intake and thus the weight gain of the pig. A total of 60 pigs (Yorkshire/ Hampshire) were used in a trial during two weeks, between 9-11 weeks of age.

Utveckling av beslutsstöd för kreditvärdighet

The aim is to develop a new decision-making model for credit-loans. The model will be specific for credit applicants of the OKQ8 bank, becauseit is based on data of earlier applicants of credit from the client (the bank). The final model is, in effect, functional enough to use informationabout a new applicant as input, and predict the outcome to either the good risk group or the bad risk group based on the applicant?s properties.The prediction may then lay the foundation for the decision to grant or deny credit loan.Because of the skewed distribution in the response variable, different Sampling techniques are evaluated. These include overSampling with SMOTE, random underSampling and pure overSampling in the form of scalar weighting of the minority class.

Bottensedimentets betydelse för flodpärlmusslans föryngring ? en metodutveckling

The freshwater pearl mussel Margaritifera margaritifera is an endangered species. To survive, the young mussels demand a fairly coarse bottom material containing an appropriate quantity of organic substrate to survive without suffocating. In order to estimate if a bottom is suitable for juvenile mussels, samples of the sediment are needed. To obtain samples a Sampling device called the Mulv collector has been developed within this project. Bottom samples were collected from 18 stations in 4 south Swedish streams, Vramsån, Kling-storpsbäcken, Brönnestadsån and Bräkneån.

Stickrädda : rapporterade upplevelser från hälso- och sjukvård

BakgrundStickrädsla upplevs av var tionde person där rädsla kan beskrivas som en irrationell eller överdriven reaktion på en uppfattad hotande situation. Orsaken till rädslan beskrivs bero på ärftlighet och/eller inlärning, där symtomen som förekommer är framförallt av vasovagal karaktär. Vårdpersonalen har betydelse vid hantering av stickrädda personer, där en kompetent och lugn personal kan förmedla trygghet till patienten.SyfteSyftet var att beskriva stickrädda personers upplevelser av vården vid stickrelaterade ingrepp.MetodEn kvalitativ forskningsmetod med en semistrukturerad intervjuguide användes där inklusionskriterier inkluderade en ålder mellan 18- 65 år, anser sig lida av stickrädsla och inneha erfarenheter av stickrelaterade ingrepp. Convenience Sampling samt snowball Sampling användes som datainsamlingsmetod. En intervjuguide skapades och testades med två pilotintervjuer där totalt åtta intervjuer genomfördes och spelades in med ljudbandspelare.

Energibalans Dåva Kraftvärmeverk

To be able to measure high-surge voltages and transients with short rise times youneed measuring instruments with a high Sampling frequency and large Bandwidth.These surges and transients occur primarily at lightning but can also occur at forexample at connecting errors at an electrical switch-gear. This report describes thework with finding two solutions for measuring and log data from these surges andtransients. One temporary solution where a measurement program has beendeveloped. A second solution where different company solutions have been analyzedto decide which fits best. For these measurement solutions two solutions for bringingdown the voltage has been used.

The thinning Quotient - a relevant description of thinning?

Det finns en rad satt att beskriva gallringsformen. Ofta används begreppet gallringskvot i dessa sammanhang utan att närmare ange vilken metod eller definition som använts for att beräkna den. Detta kan lätt leda till att missuppfattningar uppstår. Denna studie belyser olika definitioners känslighet for bland annat beståndsstruktur, gallringsform och stickvägsavstånd. Studien innehåller dessutom en jämforelse mellan olika metoder att mäta och uppskatta gallringskvoten i ett bestånd.

Magnesiumintagets betydelse för blodtryck och magnesiumkoncentrationen i stickprov av urin, träck och blodplasma hos häst

The purpose of this trial was to evaluate the possibility to use Sampling of faeces, urine and plasma, and measurements of blood pressure as methods of discovering hypomagnesemia in horses, as well as the application handiness of these methods. The most commonly used method of checking the magnesium status of a horse is to analyze samples of serum or plasma. The trial was of a switch-back design, in which the horses were used as their own controls. The animal material was five Swedish warm blooded trotters between six to ten years old, and weighing between 485-620 kg. The trial consisted of three periods that were two months each.

Simulering av simulinkmodeller medExtended Kalman FilterTidsoptimering av integrering

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

Attraktion: en fenomenologisk studie om upplevelsen av att attrahera

The aim of this study was to investigate how individuals perceive the process of sexual/romantic attraction. A phenomenological approach was used, where the participants were asked to reflect as freely as possible upon a question formulated by the authors. 13 persons were selected through purposive Sampling, eight men and five women, all between 20 and 30 years old were interviewed but only 8 were analyzed through phenomenological based software MCA-Minerva. The results showed that all participants talked about three steps; eye contact, closing the distance and conversation. In the latter step they differed regarding actions taken to attract.
