Skilda världar? Publiceringsmönster och synen på publicering vid två vetenskapliga institutioner
This Master?s thesis aims to map and analyse publishing patterns at two academic departments at the University of Gothenburg - the department of Physics and the department of History. The investigation has been guided by a set of questions: Who chooses to publish their scientific outcomes? In which forums do they publish findings? In what kind of media are the results published? What type of findings get to be published? The departments' publication lists have been examined, covering the years 2004-2007. Furthermore, ten scientists have been asked to describe factors contributing to their individual publishing pattern.
Utvärdering av kapillärt protrombinkomplex i EDTA-microtainerrör
Blodcirkulationen är essentiell för människans överlevnad. När blodets koagulation- och antikoagulationssystem kommer i obalans kan koagelbildning orsaka venös tromboembolism, blodpropp. Patienter som har haft en blodpropp behandlas med antivitamin K-läkemedel (Waran®) för att förebygga recidiv. Dosen är individanpassad och för att erhålla rätt terapeutisk verkan krävs övervakning genom mätning av protrombinkomplex i plasma.Syftet med studien var att utföra en utvärdering samt göra en hållbarhetsstudie på en ny provtagningsrutin för kapillära protrombinkomplex.I studien ingick 48 personer varav 33 män och 15 kvinnor. Åldersfördelning var 22-88 år och medianålder var 62 år.
Ragdolls : En verletimplementation
Det huvudsakliga syftet med denna rapport är att genomföra och testa en implementationsteknik för ragdolls ämnade användas i spelsammanhang. Implementationen sker genom en kombination av en verletimplementering tillsammans med en fördefinierad bone-hierarki i meshen som skall användas. Verletimplementeringen programmerades som en grund till en enklare fysikmotor och parsningen och struktureringen av meshen sköttes parallellt utanför fysikmotorn. Rotationsmatriser för samtliga större kroppsdelar, såsom över- och underarmar, överkropp, huvud etc. beräknas sedan i fysikmotorn och används för att vrida mesh-kroppen rätt.
Högfrekventa tryckvariationer under de senaste århundradena
Long time-series of pressure measurements often have high quality because the early instrumentsare more or less the same as the modern ones. A time-series from Lund consisting of three dailymeasurements from 1780-1997 has been homogenised and is therefore suitable for analysingpossible influences of the enhanced greenhouse effect. According to a two-layer model of theatmosphere one finds a shift in the frequency of baroclinic instability due to an increasedtemperature gradient caused by the increasing CO2. Baroclinic instability over the Atlantic Oceanis the main cause for frontal zone production, causing cyclonic activity over the southern part ofScandinavia. Changes to the baroclinic instability would therefore be traceable in the time seriesfrom Lund.
Buprenorfin till get : grundläggande farmakokinetik och påverkan på beteende
In this study the opioid buprenorphine was given to 8 clinically healthy goats. The pharmacokinetics and behavioral effects were studied. Injections of buprenorphine, 0.02 mg/kg body weight was given both intramuscularly (i.m.) and intravenously (i.v.) with a cross over design. The results showed a short half-life of the drug in the plasma, 65.9 ± 17.4 min (mean ± SD), after i.v. injection.
Peritonitis in horses : a retrospective study of 69 cases admitted to a university hospital during a ten year period
Peritonitis is a potentially life-threatening disease in horses. With no published work from Sweden, the objective of the study was to describe the occurrence and demographics of horses with peritonitis and to evaluate the outcome of treatment in terms of short-term survival during a ten-year period in a large clinic in Sweden.
Data were examined in a retrospective manner in 69 horses diagnosed with and treated for peritonitis at Universitetsdjursjukhuset (UDS) in Uppsala between 2002-2012. Demographic data examined included age, breed, gender, history, duration of illness before arriving at UDS, reason for seeking veterinary care, initial clinical findings (general state of health, heart rate, respiratory rate, mucous membrane appearance, rectal temperature, abdominal sounds, rectal examination, nasogastric tube results), abdominocentesis results (abdominal fluid analysis including visual inspection, leukocytes and protein, cytology, bacterial culture and sensitivity pattern), complete blood count (CBC), Serum amyloid-A (SAA) upon presentation and a follow up, plasma fibrinogen, plasma protein and albumin, treatments, length of hospitalisation and outcome.
All medical records with the diagnosis of peritonitis were extracted from the medical records system Trofast. All records with any other diagnosis code referring to trauma such as rectal tear or ruptured uterus, recent abdominal surgery, external trauma or rupture in the gastrointestinal tract were excluded. To be included in the study, the peritoneal fluid should contain more than 20.000 cells/?L, have a peritoneal protein value of >30 g/L; or have a significantly changed peritoneal fluid sample (orange with increased turbidity or worse) in cases where no data on cells or protein were available.
The horses were divided into two groups; one where the peritonitis was deemed to have an idiopathic aetiology (primary peritonitis) and the other group where the peritonitis had a possible aetiology such as intestinal parasites, impaction etc.
Vind i bebyggd miljö
Målet med detta examensarbete har varit att undersöka kunskapsnivån angående vind i bebyggd miljö hos verksamma inom stadsplanering, arkitekter och inom berörda utbildningar samt tillgängligheten på hjälpmedel och information.
Vinden påverkas starkt av landskapets utseende. Skog, hav, stad och kuperad terräng har alla olika vindförutsättningar. Inom urban miljö bestäms vindförhållandena av bebyggelseutformningen och byggnadernas omgivning.
Historiskt har vindplanering varit en naturlig del av planerandet, inte minst då det gäller jordbruk. Under årens lopp har människor tagit lärdom av tidigare erfarenheter vilket har lett oss fram till dagens kunskapsläge med en rad olika tumregler och hjälpmedel, varav det senaste består i numeriska datorbaserade analysverktyg så som Computational Fluid Dynamics.
En god och komfortabel utemiljö utgår ifrån hur vi människor upplever den.
Bremsningens effekter hos häst : utvärderat med hjälp av termografi, hormonanalyser och hematologi
Twitching is frequently used in horse management because of its sedating and pain-relieving effects. In this study, the effects on the horse?s nervous system by twitching were investigated by thermography of the skin temperature. The temperature is regulated by the sympathetic nervous system through postganglionic sfincters at the capillaries of the skin. The effects on the endocrine activity have also been studied by the measuring of ACTH and cortisol in blood plasma.
En jämförande studie mellan kreatininkoncentration i serum och GFR mätt med scintigrafi hos hund med misstänkt kronisk njursjukdom
Both serum creatinine and measuring GFR can be used to evaluate renal function in dogs suspected to have chronic kidney disease (CKD). Although high creatinine levels usually indicate renal disease, normal creatinine levels can be present in dogs with decreased renal filtration. Measuring GFR is generally believed to be the most accurate way of detecting decreased renal filtration and scintigraphy GFR using 99mTc-DTPA has been found to correlate well with the ?gold standard? inulin clearance method.When measuring GFR by scintigraphy, 99mTc-DTPA is injected intravenously and radioactive decay of technetium gives rise to gamma radiation, which is registered by a gamma camera. Pictures and curves of radioactivity in the kidneys are generated by means of a computer program.

Kartläggning av användningen av slaktblod i Sverige
Syftet med detta arbete var att genom litteraturstudier kartlägga använd-ningen av slaktblod i Sverige. Då dagens debatt angående kött-konsumtionens miljöpåverkan inte tar upp tillvaratagandet av slaktbi-produkter var även detta en intressant aspekt att titta närmare på.
Kartläggningen har koncentrerats på uppsamlingen och använd¬¬¬ningen av slaktblod från gris då detta är mest förekommande inom livsmedels-framställning i Sverige.
Informationen har hämtats från vetenskapliga artiklar och studier som hittats via databaser. Studierna är främst från de 20 senaste åren men även tidigare då det inte alltid funnits tillräckligt med ny forskning och resultat att ta del av.
I Sverige används slaktblod främst till biogödsel, energiutvinning och djur-foder men även en del till livsmedelsframställning via förädling till plasma-protein och hemoglobinpulver. Plasmaprotein används i stor ut¬sträckning som emulgeringsmedel i charkuteriprodukter och hemoglobin¬pulvret går främst till tillverkningen av blodmat. Hur stora andelar som går till respek-tive process är inte fullständigt kartlagt.
Cystocentes versus spontankastad urin : tillförlitlighet vid klinisk diagnostik hos tik
This master thesis was conducted in order to investigate the effects of the browsing
species Yeheb on animal tissues in Swedish landrace goats and to make a literature
review in order to increase the knowledge of the importance of this plant for livestock
production in Somalia. The evergreen Yeheb bush is a very important feeding source for
grazing and browsing animals in Somalia during the dry period. Yeheb contains
cordeauxiaquinone that stains the bones of the animals red/pink, which has been an
increasing problem when exporting meat to foreign countries. In an experiment, two
goats were fed dry and fresh leaves from the Yeheb bush for one and two months,
respectively. The goats did not feed the intended amount of dry leaves, since the supply
and palatability was not as high as estimated.

Investigation of tissue factor mRNA levels in human platelets using real-time PCR
Tissue factor (TF), a 47 kDa glycoprotein, is the initiator of the extrinsic pathway of blood coagulation and consequently of the upmost importance when damage to blood vessel occurs. The source of TF in circulation has been investigated. However, the source of TF is still not clear. One theory is that platelets express and increases the expression of TF after stimulation and the aim of our report was to investigate whether platelets really are a source for TF in circulation.Using specific primers for TF mRNA, platelets in plasma from healthy volunteers and from patients suffering from cardiac infarction were analyzed by using real-time polymerase chain reaction (PCR). Gel electrophoresis was performed after amplification of TF mRNA to verify the results.The samples were negative for TF when using real-time PCR and the few positive all had cycle threshold (Ct) values above 35.
