Indirekt blodtrycksmätning hos hund och katt :

The objective of this study was to study the agreement between two methods of indirect bloodpressure measurement in dogs and cats and to establish the within-method variation for the methods. The utility and practicality in the clinical setting were also evaluated for the both methods. The techniques evaluated were the oscillometric method and the Doppler ultrasonographic method. Thirtytwo dogs and 26 cats were used in the study and seven dogs and five cats out of these animals had diseases that may effect the bloodpressure. Bloodpressure was measured in both anesthetized and in conscious animals.

Styrkor och svagheter med problembaserat lärande-en metastudie

AbstractProblem-based learning (PBL) was from the beginning developed in medical school, but is today used in education in other programmes as well. Investigations about PBL have been conducted in different disciplines and there is also metastudies. In this paper, a metastudy of 8 bachelor degree papers have been conducted. The questions answered were: which methods were used to investigate PBL in primary, lower secondary and upper secondary school,which advantages were found in working according to the PBL method, which disadvantages were found in working according to the PBL method and did teachers and students views about advantages and disadvantages about PBL as a method differ and if they did, how? The results showed that mostly qualitative methods were used to investigate the PBL as a method, mostly abilities of social qualities and independence were trained in working according to PBL, a disadvantage was that working according to the PBL method was considered more resourse consuming than traditional teaching methods and teachers and students views about PBL did not differ considerably.

pm3-revision : En välgrundad metodutveckling av metod för revision av förvaltningsstyrning

In the field of maintenance management there are but a few models an organization can use. The one model that has risen to the status of being the de facto standard in Sweden is pm3(på maintenance management model). The aim of this study is to lay the groundwork for a new method of evaluate the use of pm3within organizations. Today there is no uniform way of performing such an evaluation, which is necessary in order to diagnose the performance of the systems maintenance organizations.In the process of creating our own method for performing this kind of pm3audit, we further developed the ideas from a study by Lagsten & Nordström (2013) that was performed at the county Region Skåne. The authors of that study had developed ideas about using method rationale as a basis of creating a method for pm3auditing.

Diskontinuerliga Galerkinmetoder för initialvärdesproblem och prissättning av optioner

Efficient numerical methods for option pricing is an active field of research. This project has the goal to examine possible ways to improve an established method of numerical pricing. The method is based on an adaptive finite difference method in price and uses the backwards differentiation formula of order 2, BDF2, in time. The project will focus on improvements to the time integration through implementation of discontinuous Galerkin methods, dG. Empirical convergence and accuracy results are obtained for equidistant dG-methods up to order 3 and performance is compared to BDF2.

Jämförelse av metoder för peroxidbestämningar i bränslen : A comparison of methods for determination of peroxide content in fuel

New energy resources that can replace petroleum diesel are needed and biodiesel may be an excellent substitute. During storage and use, biodiesel can oxidize and form peroxides, leading to degradation of the fuel. It is therefore important to determine the peroxide content of the fuel. In this thesis the triphenylphosphine method, which involves GC-MS analysis has been compared to the standard iodometric method which involves titration with sodium thiosulfate. Working standards were made to see how well the iodometric method worked and also in order to make a calibration curve in GC-MS.

Bakteriella virulensfaktorer : studie kring adhesiva egenskaper hos Plesiomonas shigelloides

Plesiomonas shigelloides är en gramnegativ, oxidaspositiv stav som tillhör familjen Enterobacteriaceae. Den förekommer naturligt i sötvatten, samt som normalflora hos vissa fiskar, (6, 16) och anses vara en ökande och hittills underdiagnosticerad orsak till gastrointestinala störningar hos både människor och djur (7,8,9). Mekanismerna kring enteropatogeniciteten hos P. shigelloides är ännu inte klarlagda. Det finns ett flertal potentiella virulensfaktorer som kan vara involverade i sjukdomsförloppet.

The live work method is a type of maintenance that can be done, on lines or stations, even though they are still energized. The purpose of this thesis has been to map the present live work situation at these levels in Sweden. The study is based mostly on interviews with people who have specific field competence with in live work but also with personnel at Svenska Kraftnät.

Tiludronsyra till häst : farmakologi och terapeutiska effekter

Hältor och ledskador är inom hästvärlden vanliga problem av stor betydelse som ofta är svåra att behandla. Exempel på skador inom de här kategorierna är spatt och strålbenshälta. På senare år har bisfosfonaten tiludronsyra börjat användas mot dessa åkommor för att hämma benresorptionen. Substansen finns som godkänt läkemedel till häst i ett antal europeiska länder men finns endast tillgängligt som licensläkemedel i Sverige. Syftet med denna litteraturstudie är att redogöra för tiludronsyras verkningsmekanismer, effektivitet och säkerhet. I kroppen binder tiludronsyra till hydroxyapatit som är en beståndsdel i kroppens benmineral. Substansen verkar genom att hämma benresorptionen på olika sätt.

Va?rdering av varuma?rken : - En kvalitativ studie om problematiken kring vilken metod som anva?nds vid fo?rva?rv

Background: Associated with the change in the regulations in 2009 concerning how goodwill should be handled in the acquisitions, brand valuation is increasingly recognized. Goodwill will now be identified and the brand will therefore be separated to be individually evaluated. The valuation has a problem with a number of factors that will influence the choice of method, to obtain a reliable value Aim: The purpose of this study is to examine the method used for brand valuation associated with the acquisition situations. In addition, it aims to gain a better understanding of brand valuation and its problems.Method: The study has a qualitative basis, where three key people of brand valuation have been interviewed. These work as valuation specialists at various accounting firms, this to get answers that could be compared.

Under parasollen : En komparativ studie utifrån whole language-teorin och LTG-metoden

AbstractThe purpose of this study is to analyse the reading- and writing-approaches: the LTG-method and the whole language-theory. The attention is to perform a comparative literate-study to distinguish their similarities and differences, and examine which one of the approaches that is most clearly anchored in the syllabus of the subject Swedish. The starting-point of the study is the questions: Which similarities respectively differences have the LTG-method and the whole language-theory? Which one of these theories is most clearly anchored in the syllabus of the subject Swedish? The study has shown that both the whole language-theory and the LTG-method can anchor in the syllabus for Swedish. However the whole language-theory has stronger hold in the syllabus, as the whole language emphasises the meaning of literature for reading- and writing-learning, and considers the pupils reflection during their learning-process and conquered knowledge-goal.

Utveckling av HPLC-metoder för kvantifiering av nyckelkomponenter i en villkorad emulsion

Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.

P?m?rkning vid virkesberedning - Bastning. Ett hantverksf?rs?k

This essay aims to investigate a rare method of marking up timber before hewing it. The method for marking up timber is by eyesight, where visual judgment and the use of a broad axe are the tools employed. The broad axe is driven through the bark and exposes the inner bark in a straight line. The method is described by a craftsperson dating back to the 1930s. There is a lack of information regarding the method.

Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods

Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).

Immunterapi mot melanom - är adoptiv immunterapi framtiden?

Melanom är en av de mest immunogena (immunstimulerande) tumörformerna och immunterapi har därför varit en behandlingsform som studerats för att undkomma de svåra biverkningar som erhålls vid de konventionella behandlingsmetoderna, som cytostatika och strålning. Det finns många olika strategier för att inverka på och aktivera immunförsvaret och flera immunterapier finns redan godkända och används idag för behandling av melanom. Flera av dessa terapier verkar dock genom att generellt stimulera immunförsvaret vilket resulterat i betydande biverkningar samt haft förhållandevis liten effekt mot tumörerna. Endast en liten andel (som högst 6%) har uppvisat en så kallad fullständig respons, det vill säga blivit helt fria från tumörer vid dessa behandlingar. Adoptiv immunterapi går ut på att man ?tränar? och aktiverar patientens egna T-celler in vitro att känna igen och angripa tumörceller och återinjicerar dem sedan, vilket resulterat i en mer riktad behandling med flera gånger högre effektivitet mot tumörerna jämfört med andra immunterapier och man har nått upp till en fullständig respons på 22 %. Det är en komplex metod med flera olika steg där utvecklingsmöjligheter finns.
