Evaluation of a Flow Cytometry Method for Identifying and Quantifying Fetal Red Blood Cells in Maternal Blood
Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.
Metodutveckling för analys av serglycinuttrycket i blodet hos hundar :
The development of quantitative, real-time PCR (qPCR) combined with the mapping of the canine genome opens new possibilities in veterinary medicine. This method provides a quick and accurate quantification of the expression of a specific gene at a given point in time and thereby also information of how the gene expression for a certain protein is influenced by various conditions and diseases. One possible area of application is identifying bio markers for cancer. Recently the protein serglycin (the core protein of an intracellular proteoglycan) was found to act as a selective marker for the disease acute myeloid leukemia in humans (Niemann et al, 2007). Serglycin is produced by most hematopoietic cells, although mast cells account for the largest amount of serglycin.
Vilken preferens har tjockskalig målarmussla (Unio crassus) för bottensubstrat och vattenhastighet i Storån, Östergötland?
The thick shelled river mussel (Unio crassus) has a fragmented distribution in southern Sweden. It is a threatened and protected species. In both the Swedish red list and the IUCN Red List of Threatened Species Unio crassus is classified as Endangered (EN). Causes for this classification are for instance differentiated bottom substrate and deterioration in water quality. In this study, habitat preferences of Unio crassus were investigated to assist in future restoration work.
Pedagogers tankar och arbetssätt kring elever med koncentrationssvårigheter
The purpose of this thesis is to find out if principals and teachers have experience, expectations and thoughts about the differences that the new Education Act means in relation to the old one about action programme. Through qualitative interviews with two principals and four teachers, I have tried to answer my research questions that I have made based on the purpose. The questions are: How do the interviewees describe the routines about action programme? Has, according to the interviewees, the routines been changed with the new Education Act? How do teachers and principals experience the differences between the old and new Education Act regarding the action programmes?The results of my survey shows that the process of action programme is different at different schools and that it has been adapted to the new Education Act in varying degrees. These results give differences in the experiences of the new directives.
Definitioner av mobbing : Menar kuratorn samma sak som forskaren och eleven?
Bullying can have serious consequences on everyone involved. Consequently it is important that school counselors are able to intervene. Thereby they need an unambiguous definition and knowledge about bullying that has been produced from research so they do not make mistakes that could lead to further damaging of the students. Thus the aim of this study was to examine how school counselors define bullying compared to the views held by scientists and students in secondary school. Through a review of previously done research the definitions of scientists and schoolchildren was summarized.
Hur ser lavars fördelning ut runt stammen på ek, och påverkas den av trädets storlek och dess närmiljö?
The aim of this study was to describe preferences of geographic direction of ten, oak-living epiphytic lichen species and how they responded to sun exposure, nearby bushes and trees, bark fissure depth and circumference. The frequency of every species was recorded in arcs of ten degrees around the tree at a height of 130 to 180 cm above the ground. An estimation of the amount of every species in every arc was also recorded. To analyse how the distribution of the lichen species responded to the different factors their concentration for every tree was plotted against the four factors. The distribution of Cliostomum corrugatum had a positive response to high sun exposure and a negative response to a thick layer of bushes and trees.
Comparison between different freezing and thawing methods for human spermatozoa
Preservation of cells and tissues by freezing at temperatures below 70°C has led to new possibilities for the storage of germ cells for fertility preservation. During the freezing process problems might occur, the greatest being ice crystallization which can cause membrane destruction and thus cell death. To minimize this risk, solutions that reduce the freezing point can be added to reduce crystallization and increase survival rates. These solutions are called cryoprotectants. The best method for freezing is still not known.The aim of this study was to analyze the effect of various parameters on the survival rate of human semen frozen with liquid nitrogen.
Factors affecting the heifer´s age at pregnancy
Several factors affect the heifer´s growth and development, the newborn calf´s feeding of co-lostrum during its first hours of life is one important factor. The colostrum contains higher amount of immunoglobulins and insulin growth factors compared to matured milk. A high intake of immunoglobulins from colostrum results in a high blood concentration of immuno-globulins until the age of eight months. This leads to a lower incidence of diseases that can affect the growth and development negatively. Diarrhea is the most common disease in calves younger than 30 days.
Personlig lämplighet : Värderingsgrund vid rekrytering
Commercial expropriation occurs when real property is compulsory acquired by a private operator. This phenomenon is relatively new and has been criticized not only because of the rules concerning compensation, but also from the point of view of permissibility.An intervention in the protection of property must fulfill the requirement of important public interest set out in RF 2 kap. 15 § in order for it to be allowed. There is no definition regarding what constitutes an important public interest, the only thing that exist is a non-exhaustive list in the preparatory work. This in turn has led to the creation of a broad discretion when it comes to determining what constitutes important public interests.
Applikationsintegrering - en analys av metoder och teknik
Abstract
In the contemporary world of information technology you find a multitude of
applications and systems covering a broad spectrum of areas of need in
different companies. One effect of this multitude of programs is the difficulty
to make them exchange information with each other or to collaborate, since they
are developed by different programming languages for different platforms, with
different standards and different data formats.
Our aim with this work is to describe how it is possible to tie these programs
together to make them actually communicate with each other in order to exchange
information, share their native methods and also to become a part of the
overall business processes. In this integration task you will, among other
things, find different levels of application integration such as data level,
method level, application interface level and user interface level integration.
Application integration also involves hardware components, called middleware,
that facilitate the physical connection between applications. There is a range
of different middleware products offered today on the market.
Internprissättning i internationella läkemedelskoncerner
The aim of this essay was to study how the communities work with groups as a support to children with addictive parents, and to increase my understanding of the groups meaning as a support. My main questions have been: How are the child group sessions formed? What kind of experience does the group leaders have regarding their functions? The study is a qualitative investigation that has been turned to prefessionals in the subject area and is based on 6 interviews and secondary sources. The material has been analyzed from a narrativ theory as well as a salutogent perspective. Research shows that children growing up in an addictive environment often have decreased psychological health and are overrepresented amongst those who developed a future addiction.

Storjuktan ? Rekonstruktion av ett sekels kvicksilverbelastning. : En undersökning av kvicksilverkoncentrationer i daterat bottensediment.
The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.
Globaliseringens och professionaliseringens effekter på styrelsesammansättningen i svenska börsbolag: En social nätverksanalys baserad på delade styrelseledamöter under perioden 1990 till 2010
The purpose of this thesis is to examine the networks of interlocking directors in the 50 largestSwedish companies on the Stockholm Stock Exchange during the years 1990, 1995, 2000, 2005and 2010 and seek explanations for the observed developments.Our findings indicate that the density and concentration of the network has decreased during thefirst ten-year period and stayed constant during the second period. The development of theoverall network is not consistent throughout all corporate groups. Most notablyHandelsbankssfären seems to experience increased density and connectivity whileWallenbergsfären is experiencing the reverse.The changes during the first ten-year period is deemed to come mainly from changes inregulations pertaining to both the opening for international capital investments as well as looserrestrictions on domestic capital investments. These changes have caused decreased concentrationof ownership, as well as the emergence of new owners, which is reflected in the board ofdirectors.During the second ten-year period the changes are more pertaining to the individual boards andboard members, without flowing through into the overall network. Our findings indicate thatthese changes are caused by the increased professionalization of boards and board work, whichhas gained momentum through the creation of the Swedish Corporate Governance Code..
