Popular Abstract in Swedish Blodgruppering med genteknik - studier av ABO-systemets arvsanlag Populärvetenskaplig sammanfattning på svenska Blodtransfusioner som utfördes före sekelskiftet slutade ofta med svåra komplikationer och i många fall patientens död. Scenariot förändrades dramatiskt till det bättre i och med den österrikiske läkaren Karl Landsteiners upptäckt av blodgruppssystemet ABO (The ABO blood group system is undoubtedly the most important genetic and phenotypic marker in clinical transfusion medicine. The A and B determinants are immunodominant, terminally located carbohydrate residues of glycoconjugates on erythrocytes and other cell surfaces. The enzymes responsible for assembly of these structures are glycosyltransferases encoded by the ABO genes on chromosome nine. T

This thesis is the result of three years of work in Lund University, as a member of DELPHI group, at the Elementary Particle Physics Department. The work concerns the study of Bose-Einstein correlations in electron-positron collisions at LEP. Since the Jetset event generator and its implementation of the Bose-Einstein correlation effect, LUBOEI, is the most used tool in the particle physics commun

Sudden pipe bursts occur in high-pressure water transmission pipelines and water distribution networks. The consequences of these bursts can be very expensive due to the outage time while the burst pipe is repaired, the cost of repair, and damage to surrounding property and infrastructure. As a result, it is advantageous to minimise the detection and location time after the burst occurs. Currently

Landscape change in Europe has caused the decline of many grassland species. Tephroseris integrifolia (Asteraceae) is one species which has declined rapidly in Sweden since the 19th century. A census of extant populations from 1980 to 2009 revealed a dramatic decrease in population sizes during the early 1990s, despite far-reaching conservation measures. Knowledge of causes of species decline is n

The internal bremsstrahlung from the positon decay of 82Rb has been measured in the energy ranges 0.95-1.3 and 1.7-2.0 MeV. The measured intensity was about twice the value predicted by the charge-independent theory. The external bremsstrahlung produced in stopping the positons in Be, C and Al has been measured in the same energy intervals. Energies and intensities of the γ-rays from 82Rb have bee

Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional IC engines could be saved, the fuel economy would improve. One solution to this is a pneumatic hybrid using variable valve timing to compress air during decele

14-3-3 proteins comprise a family of highly conserved proteins. 14-3-3 proteins have been found in all organisms examined except for members of the prokaryotic kingdom. 14-3-3s are involved in numerous processes in the cell and they typically bind to phosphorylated motifs in other proteins and regulate their activities. In plants, 14-3-3 proteins are recognized as key regulators of primary metabo

It has often been argued that the Earth is like an island in space and that its brittleness is most clearly reflected on small islands in the oceans. Easter Island, in particular, with its largely depleted resources, has been seen as a microcosmic warning about what could happen to our entire planet. However, the analogy of the Earth and islands with finite natural resources is not self-evident fr
