Reliable structural and statistical analyses of three dimensional protein structures should be based on unbiased data. The Protein Data Bank is highly redundant, containing several entries for identical or very similar sequences. A technique was developed for clustering the known structures based on their sequences and contents of alpha- and beta-structures. First, sequences were aligned pairwise.
The identification of a subterranean metallic ore from scattering experiments, conducted on the surface of the ground or in a bore hole, is a classic geophysical problem. In general this problem is not well-posed. However, a priori information about the shape of the target provides enough regularization to make the problem numerically stable. The problem is solved by minimizing the mean-square err
Popular Abstract in Swedish I rektorers uppdrag ingår ansvar för den pedagogiska verksamheten förändras och utvecklas. Den fråga som ställs i avhandlingen gäller om det finns en gemensam norm för hur rektorer tänker och handlar när det gäller den utvecklingsinriktade delen av ledaruppdraget. Om så är fallet hur ser den ut och kan den utvecklas? Bakgrund Stora förändringar på ett internationellt This thesis puts a focus on school leadership and school development. The local authorities took over responsibility for public education in 1991. At the same time, steerage by rules was abandoned in favour of steerage by goal-setting and result evaluation. The principal is an important link in this chain of steerage. The question posed by the thesis concerns whether there are common norms for th
Using a recently introduced multiplex polymerase chain reaction and restriction fragment length polymorphism ABO genotype screening method we have found an anomalous ABO genotype (A2O1variant) not correlating with the serological phenotype (blood group O). The blood group was confirmed by absorption/elution and detection of blood group substances in saliva. Sequencing of exons 6 and 7 in the ABO g
Three series of hard/soft styrene-acrylic latex based systems with equivalent compositions were prepared either by blending of homopolymer latexes or by preparing structured latex particles having core shell (CS) or inverted core shell (ICS) morphologies. Transmission electron microscopy (TEM) was used to investigate the particle morphologies, which were correlated to the calculated fractional rad
To describe demographics of tuberculosis ( TB) in the circle divide resund region, Southern Scandinavia, a retrospective analysis of epidemiological data from TB registers and population databases, from 1995 to 2002, was performed. A total of 2678 TB cases were reported with an overall incidence of 6.3 per 100,000 person-y of observation. There were major differences in notification rates among im
Objective: To monitor changes in serum concentrations of cartilage oligomeric matrix protein (COMP) during a 24-h period to determine any diurnal variation, and to estimate the half life of COMP in the circulation in patients with symptomatic knee osteoarthritis and in those with rheumatoid arthritis. Methods: Serum samples were drawn every 4 h (7 samples/patient over 24 h) in 10 patients with kne

In this paper an excavation of a croft from the late 19th - early 20th century is presented. The artefact-material material i discussed and compared with information from contomporary written record. The artefact material and the writte documents yielded different kinds of information.
The paper studies the conditions optimum for the proliferation of neural cells at the surface of porous silicon. The results of this study show that the best results are achieved with meso-porous silicon. Geometrical properties of the wafers are also important through charge distribution at mask edges, change of hydrophobicity, degree of oxidation, the release of adhesion proteins from regeneratin
Magnesium chelatase is the first unique enzyme of the bacteriochlorophyll biosynthetic pathway. It consists of three subunits (BchI, BchD, and BchH). Amino acid sequence analysis of the Rhodobacter capsulatus BchH revealed a novel cysteine motif ((CX2CX3CX14C)-C-393) that was found in only six other proteobacteria (CX2CX3CX11-14C). The cysteine motif is likely to coordinate an unprecedented [Fe-S]
Computing systems are becoming more and more complex and powerful. It is nowadays not uncommon to run several server applications on the same physical platform. This gives rise to a need for resource reservation techniques, so that administrators may prioritize some tasks, or customers, over others. This thesis gives an introduction to the Linux kernel 2.6 task scheduler, and scheduling related op
The GAIA astrometric mission has recently been approved as one of thenext two ``cornerstones'' of ESA's science programme, with a launch datetarget of not later than mid-2012. GAIA will provide positional andradial velocity measurements with the accuracies needed to produce astereoscopic and kinematic census of about one billion stars throughoutour Galaxy (and into the Local Group), amounting to a

Objective: To test the hypothesis that sub-optimal factors in perinatal care services resulting in perinatal deaths were more common among immigrant mothers from the Horn of Africa, as compared to Swedish mothers. Design: A perinatal audit, comparing cases of perinatal deaths among children of African immigrants residing in Sweden, with a stratified sample of cases among native Swedish women. Se
