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.

Rostfria stålkonstruktioner och rostskyddsbehandling av stålkonstruktioner enligt Eurocode

Steel is an excellent material to build with, but consideration must be given to the fact that unprotected steel corrodes, rusts, therefore, as a rule, the steel must be protected in some way. This can be done by reducing the tendency of the steel to corrode by using stainless steel or by treating the steel with a protection method. The two most common methods of protection are corrosion protection paint and zinc coating. To determine the method, the corrosive category must first be evaluated and this is done in accordance to EN ISO 12944-2:1998.Stainless steel is available in many varieties but only some of them have properties that make them suitable for use as construction steels. There are many factors to be considered in the design of stainless steel to prevent corrosion from occurring.

Klassifikation av litteratur om film och TV ? En komparativ studie av Klassifikationssystem för svenska bibliotek (SAB) och FIAF Classification scheme for literature on film and television

The aim of this thesis is to compare two different classification schemes with each other and see what the differences and similarities are when classifying literature concerning film and television. One of the schemes is of general kind, Klassifikationssystem för svenska bibliotek (SAB) and the other is a special system, FIAF Classification scheme for literature on film and television. The focus of the examination is on comparing the structure, contents and division of firstly the main classes and secondly on comparing the notation and the auxiliary tables in the schemes. The theoretical framework of the comparison is based upon theory of classification but the conclusions drawn are though mostly of a more subjective character. In addition to the comparison itself interviews have been made with four libraries, two with experiences of SAB and two with experiences of FIAF.

Flyttprocessens påverkan på identiteten ? utveckling eller avveckling? : En fallstudie kring flytten av Hjalmar Lundbohmsgården i Kiruna

The purpose of the thesis is to investigate and analyze how three different actors linked to the urban transformation in the city of Kiruna, in this case LKAB, the Municipality of Kiruna and the County Administrative Board of Norrbotten, believe that the identity of a historical monument that is marked cultural heritage is affected by future relocation. The second part of the study is to investigate the impact the building might have on the city in the future. This study is based on the relocation of Hjalmar Lundbohmsgården.The study is based on a qualitative approach in which five informants from the three actors were interviewed. The interviews have been analyzed through thematic analysis, where a combination of theoretical thematic analysis and empirical thematic analysis was used. The result shows that the new location of Hjalmar Lundbohmsgården is preferred to be in a suitable context close to other cultural buildings. All informants agree that accessibility is a fundamental element in, which a synergistic effect is an increase in visitor numbers.

Strötorvsanvändning i djurstallar : en litteraturgenomgång

Peat litter has been used in animal houses for a long time. Because of its good ability to absorb liquid and nutrients from the manure it can create a dry surface for animals and a valuable manure product. Through changes in agricultural practises the use of peat litter has diminished and is to a great extent replaced by straw, sawdust and cutter shavings although Sweden is rich in peat-findings. The aim of this work was to summarize the presented knowledge about the used of peat litter, techniques, advantages and disadvantages and to compare with other commonly used litter materials. Articles on peat litter have been searched for in magazines, databases and books at SLU library. Visits to peat industries, interviews with peat producers and with peat researchers contributed to the material. Peat is not a uniformly material.

Hållning av kastrerade och icke kastrerade försöksmöss i par som en lösning på aggressivt beteende

Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new solution was tested in this paper. The proposed solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.

Verkligt värde i praktiken : En studie av tillförlitligheten vid fastighetsvärdering till verkligt värde

The ongoing harmonization process aims to incorporate IFRS regulations into the Swedish accounting. As a consequence investment property?s starting from 2005 may be valued using the fair value method, in accordance to IAS 40. This involves major changes for listed property enterprises that from now on can value a large extent of their assets to fair value. All parties don?t appreciate this progress, opponents to fair value have expressed great concern that fair value don?t work in practice.

Unga kurdiska kvinnor : svenska & kurdiska normer inom familj och samhälle

The purpose of the study was to investigate how young female Kurd immigrants experienced their existence between two different cultures, namely Swedish compared to the immigrants parents culture. How their experience behavioural conduct between the opposite sex before marriage and if the young female Kurds thought the mass media picture of them was thought of as a correct image of their lives in general or whether they experienced it as a generalisation only. We chose qualitative methods for our study and used suitable literature based on the theories of this subject to be able to understand the problem. To go deeper whit the study five young female Kurds aged between eighteen and twenty years were asked if they would participate in an interview on the subject. These participants proved that they had no problem at all being multicultural.

Språkutveckling och organisation : En studie av mottagningsprocessen av nyanlända i en liten kommun

The purpose of these studies is to see how the reception and education of non-Swedish speaking newcomers are organized in a small county, and what you can do to improve this process to achieve a better and quicker integration into the Swedish language and society. To do this, interviews have been performed with four headmasters and different categories of teachers representing all schools in the actual county.In the result it was clear that both headmasters as teachers saw a need to change   and improve reception to provide consistent but flexible support. The headmasters wanted to create written instructions to assure equivalence between the different schools. The majority of teachers wanted to change the current system whereby some pupils, based on their origins, were placed in a preparatory class to learn the language whilst others were placed directly into a Swedish class. All teachers also thought that the help the non-Swedish speaking newcomers were offered was insufficient.The conclusion is that the county must decide and create instructions according to Skolverket?s recommendations and it also ought to offer all pupils the possibility of learning the basis of the language in a preparatory class.

Utvärdering och jämförelse av olika fälttester för fotbollsspelare

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

Kunskapssyn och behov av IKT-verktyg

In a world where digital media is becoming a greater part of people?s everyday and working lives it is plausible to assume that the upcoming generation of pupils expect the teaching media to adapt thereafter. It is this assumption of an increased demand that Natur & Kultur is hoping to be able to meet. This thesis has been a stage in the process of producing digital material in the subject of mathematics for high school students. Specifically the aims of this thesis have been to make a rough description of the largest competitive companies? products within the same market, explore and put together a brief theoretical foundation of contemporary research and produce concrete examples of ideas for digital applications.

Obstruktiv FLUTD - ett nödvändigt ont eller möjligt att förebygga?

FLUTD - Feline Lower Urinary Tract Disease ? is a complex disease and a common sight in the veterinary setting. Although FLUTD excluding urethral obstruction may be discomforting for the cat and its owner due to symptoms such as periuria, stranguria, hematuria, dysuria and pollakiuria, obstruction presents an acute and potentially lethal form of the disease as a result of uremia and disturbances in fluids, electrolytes and acid-base balances. A study of literature has been performed to investigate the causes of FLUTD with urethral obstruction and the actions available to the owner to avert them. Potential causes of obstructive and non-obstructive FLUTD have been found to include infections, uroliths, urethral plugs, neoplasia, anatomic abnormalities, trauma, neurogenic or iatrogenic causes. Most commonly a cause cannot be identified and the terms idiopathic FLUTD or feline idiopathic cystitis are used. As the mortality rate due to urethral obstruction likely is somewhere around 5.8-8.9% and FLUTD including and excluding urethral obstruction constitute great inconveniences, precautionary measures are warranted.

Identifiering av lek- och övervintringsområden för lax (Salmo salar) och öring (Salmo trutta) i Klarälven

Old hollow trees of oak contain a large amount of wood mould. Unfortunately, these trees have in the last century been greatly reduced in numbers. It has resulted in that species that depend on these habitats, saproxylic species, have become at risk to decrease in numbers or die out regionally. Previous studies have shown that the volume of wood mould is an important factor for occurrence and population size of saproxylic organisms. The aim of the present study was to examine how the volume of wood mould varies among ash (Fraxinus excelsior), lime (Tilia sp.), maple (Acer platanoides), aspen (Populus tremula) and oak (Quercus robur).
