Njurfunktion hos hypertyreoida katter : en jämförelse mellan serumkreatinin och serumcystatin C
Hyperthyroidism and chronic kidney failure (CKD) are common diseases in older cats. It can be difficult to evaluate kidney function in cats suffering from both conditions simultaneously. In the daily clinic serum creatinine is the analysis of choice when evaluating kidney function and secondary glomerular filtration rate (GFR). This marker does not, however, detect kidney damage until about 75 % of the function is lost. There are several other techniques available when investigating GFR but none are readily available for the small clinic.
Reference interval for urinary catecholamines and methylated catecholamines analysed using HPLC
Catecholamines are stress hormones that are produced and released by a rare tumor called pheochromocytoma. This tumor can cause hypertension which if undiagnosed and untreated leads to death. Since good therapy is available, it is important to find the tumor in time. The most common way to diagnose the tumor is measurement of the biochemical markers; catecholamines and their metabolites, methylated catecholamines.After observation that almost all normetanephrine results for women were higher than the upper reference limit and therefore pathological, the accuracy of the present reference intervals was questioned. Therefore new reference intervals for both urinary catecholamines and methylated catecholamines were developed by analysis of 46 samples using HPLC.
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.

Empirisk undersökning av aktieindexobligationer : Till vilken grad tar innehavaren del av underliggande index avkastning?
The purpose of this essay is to evaluate stock index bonds return to risk ratio in order to investigate to which degree an investor in a stock index bond take part of the underlying index return and what the investor must pay for the security of not losing his funds. In order to carry out this evaluation an average return per year and the Sharpe ratio will be calculated and a mean- standard deviation analysis will be made. All investigated stock index bonds are based on a Swedish underlying asset.The results show that the stock index bonds haven?t generated a higher risk adjusted return than its underlying asset. The stock index bonds took part of 57 % of the underlying assets return, and the loss of 10 percentage points per year for the stock index bonds compared to its underlying asset can be seen as the cost for the guarantee a stock index bond gives..
Redogörelse av marknadsstyrka på den svenska elmarknaden
Denna uppsats syfte är att förklara den svenska elmarknadens konkurrenssituation med Lerner index och Herfindahl index. Genom att estimera priselasticiteten med en ekonometrisk modell som logaritmerats kunde dess värde skattas fram. Vidare har denna elasticitet använts för att skatta fram Lerner index. Avslutningsvis har ett Herfindahl index beräknats för att mäta marknadens koncentration. Resultatet från empirin visar existens av marknadsstyrka på elmarknaden och att den är oligopolistisk..
Vikten av ett oviktat index
Syftet med denna uppsats är att undersöka ett oviktat index relevans som jämförelsemått för aktivt förvaltade fonders avkastning och förvaltares förmåga att hitta vinnaraktier. Arbetet använder sig av en kvantitativ metod för framtagning av ett oviktat index (SUWX 100) som inkluderar de 100 största företagen på Stockholmsbörsen. Analysen av kvantitativa data är av induktiv karaktär, och använder sig av de Sverigefonder som finns i PPM-systemet för att dra slutsatser kring det oviktade indexet som jämförelsemått. Vår slutsats är att det finns aspekter av ett oviktat index som gör det användbart som jämförelsemått för Sverigefonder..
Alternativa index - En studie av mean-variance-effektiviteten hos index baserade på fundamentalvärde kontra börsvärde
Finansiella index är viktade genomsnitt av olika tillgångars avkastning från en bestämd tidpunkt. Traditionella index är börsvärdeviktade. Problemet med denna typ av index är att börsvärdet tidvis kraftigt kan överdrivas på grund av spekulation. Alternativa index bygger på företags fundamentalvärden. De viktas därmed efter företags faktiska redovisade siffror i balans- och resultaträkningar.
Hållbarhetsredovisning : En studie av Vattenfall AB i ljuset av GRI
This essay is about democracy and how a democracy index can be used as a tool to illustratethe gap between reality and ideal. The purpose of this study can be expressed by two researchquestions: Does the Economist Intelligence Unit's (EIU) democracy index illustrate thedistance between reality and the ideal of democracy presented by Dahl? and Can the EIU'sdemocracy index be modified by a) internal adjustments and b) using the variables includedin World Economic Forum?s (WEF) equality index?By using a combination of theories (Dahl?s theory of democracy, Rawls theory of justice andchosen theories critical to liberal democracy) as an analytical framework the following twoquestions have been answered:1) Which of the variables included in the EIU's democracy index have the potential to capturethe level of political equality?2) Which of the variables included in the WEF?s equality index have the potential to capturethe degree of political equality?By using a quantitative method the study?s third and last question has been answered:3) How strong is the rank correlation between the EIU?s democracy index and the WEF?sequality index, that is; how strong is the rank correlation coefficient (rho)?The data presented by the WEF?s equality index indicate that women are systematicallydiscriminated against as a group. From a democratic perspective the EIU may need tomeasure inequalities at a group level in order to capture the lack of political equality betweenindividuals. By reformulating some of the EIU?s variables, by revising the EIU?s point systemand by using the variables included in the WEF's equality index to extend EIU?s democracyindex, the chances of capturing the gap between reality and the ideal of democracy presentedby Dahl would likely increase..
Utvärdering av ett mikroalbuminuritest till hund :
The occurrence of small amounts of albumin in urine, microalbuminuria (MA), is used both in human- and veterinary medicine as an indicator for patients who have developing proteinuria. Proteinuria can be prerenal, renal or postrenal which is important to establish during an investigation. With conventional methods decreased renal function is not detected until 70 % of renal function is lost. The ability to detect and start a treatment earlier might reverse or slow the progression of disease.
The purpose of this study was to investigate the reliability of Heska® E.R.D.-Health Screen?, a test for microalbuminuria in dogs, to detect albuminuria.

The Value of Digital Information DIV-index, A Corporate Asset
Companies have in the past decades changed fromtraditional manufacturing organizations into serviceorganizations. For these service organizationsinformation and competence have become animportant resource. The traditional view oninformation is that an employee use and search forinformation to reduce uncertainty for their decisionmaking. Even though information is strategicallyimportant for organizations, information is not valuedin any way. Hence, this thesis aims to valueinformation in terms of the utility it brings to theorganization.The conclusion is that four factors are important whenvaluing information in terms of utility.
Aktieindexobligationer : Småspararens Livbåt på Vägen mot Djupt Vatten?
The main purpose of the essay was to evaluate whether investments in index-linked bonds were suitable investments for smaller investors on the international finance market. To determine whether the index-linked bonds are good investments, the variables yield, cost and risk were used to measure the index-linked bonds against investments in stocks and funds. The reason for the interest in this subject is that investments in index-linked bonds have grown furiously the last few years. With the growth of the investments the criticism of index-linked bonds has also grown stronger. The critics? main point is the cost of the product, and they imply that investors can create their own index-linked bond and thereby avoid the bank fees.This study used a quantitative approach, because all the data of yield, cost and risk consist of numbers.
Fundamental indexering - fundamentalt rätt?? : En studie av den svenska aktiemarknaden
I denna undersökning konstrueras fundamentala aktieindex med aktier innefattade av indexetStockholm OMX30 under perioden 1999-04-01 till och med 2009-03-31. Dels konstruerasenskilda index där indexeringen sker efter faktorerna bokvärde, utdelning, försäljning, resultat,kassaflöde och antal anställda, dels ett index där faktorerna sammanvägs. Detta för att undersökahuruvida fundamentala index bättre speglar företags fundamentala värde och därmed genererarhögre riskjusterad avkastning i förhållande till ett marknadsvägt referensindex. De enskildaindexen bokvärde, utdelning, försäljning, antal anställda samt det sammanvägda indexet visarhögre riskjusterad avkastning än referensindexet. Kassaflödes- och resultatindexet presterardäremot markant sämre än referensindexet.
Automatisk bedömning av reglerkretsarsprestanda
In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.
