The low-lying core-excited quintet states of Mg I have been studied experimentally and theoretically. On the basis of beam-foil spectroscopy, the energies of nearly all the quintet levels belonging to the 2p(5)3s3p2 and 2p(5)3s3p4s configurations have been established, while only 5F levels from the 2p(5)3s3p3d configuration could be identified. Multiconfigurational Hartree-Fock calculations, inclu

CP and T asymmetries in neutrino oscillations, in vacuum as well as in matter, are expressed in terms of invariant functions of lepton mass matrices.

Objectives To determine the accuracy of established ultrasound dating formulae when used at 12-14 and 15-20 gestational weeks. Methods A total of 363 singleton pregnancies conceived after in-vitro fertilization (IVF) and randomized to a dating scan at 12-14 or 15-20 gestational weeks were studied. 'True' gestational age was calculated on the basis of the day of oocyte retrieval and was compared to

Syftet är att studera och analysera processer vars mål är att förändra vardagen för två marginaliserade grupper, så att de i större utsträckning blir delaktiga i samhället. De två undersökta grupperna är manliga unga narkomaner och äldre utvecklingsstörda. Avhandlingen består av tre geografiska perspektiv: 1) det tidsgeografiska synsättet, 2) känslan för platsen och 3) socialgeografiska teorier omThe aim is to study and analyse processes intended to change the daily lives of two marginalised groups and enable them to participate to a greater extent in the community. The two marginalised groups are young male drug addicts and older intellectually disabled. The thesis is permeated by three geographic perspectives: 1) the time-geographic approach, 2) sense of place and 3) social-geographic th

The intestinal mucosa represents the largest body surface toward the external environment and harbors numerous T lymphocytes that take up resident within the intestinal epithelium or in the underlying lamina propria (LP). The intraepithelial lymphocytes include subsets of 'unconventional' T cells with unclear ontogeny and reactivity that localize to this site independently of antigen-specific acti

For generations of electrocardiogram (ECG) analysis, the presence of premature ventricular beats (PVBs) has been characterized as a common event in the ECG without regard to the mechanism which has caused the PVB in the first place. At best, the coupling interval with the preceding sinus beat may be noted. This viewpoint persisted throughout the era of automated ECG analysis, as well as influencin

A pair of isogenic, nontypeable Haemophilus influenzae strains, one expressing protein D and the other protein D-negative, was compared in their ability to cause damage in a human nasopharyngeal tissue culture model. Damage was assessed by measuring the ciliary beat frequency (CBF) of tissue specimens at 12 h intervals. Cultures inoculated with H. influenzae manifested a decrease in CBF beginning

Bertrand supergames with non- binding communication are used to study price formation and stability of collusive agreements on experimental duopoly markets. The experimental design consists of three treatments with different costs of communication: zero- cost, low- cost and high- cost. Prices are found to be significantly higher when communication is costly. Moreover, costly communication decrease

We show that the Galactic thick disk reaches at least solar metallicities and that it experienced strong chemical enrichment during a period of ~3 Gyr, ending around 8-9 Gyr ago. This finding puts further constraints on the relation and interface between the thin and thick disks and their formation processes. Our results are based on a detailed elemental abundance analysis of 261 kinematically sel

Over the last decade it has been ever increasing interest in developing alternative sanitary systems, which would be more sustainable than a conventional one is. In Sweden urine separation has been considered a promising approach towards increasing recycling of wastewater nutrients. Full scale trials are carried out and examined. This paper presents a study on implementation of urine separation sy

In NW Patagonia, Argentina, poor regeneration after fires of Nothofagus pumilio (Poepp. and Endl.) Krasser forests located in drier environments has been attributed to probable edaphic changes. We studied the long-term effects of wildfire on the mineralogical, physical, chemical and biological properties of a soil developed from volcanic-ashes under N. pumilio forests. Soils from six small patches

The Zn-61(30)31 isotope has been produced at the Oak Ridge National Laboratory in the fusion-evaporation reaction Ca-40(Mg-24, 2pn)Zn-61 at 104 MeV. The experimental set-up allowed gamma-rays to be detected in the CLARION Ge detector array in coincidence with the detection of recoiling nuclei in the focal plane at the end of the recoil mass spectrometer. This provides a unique identification of ga

Background. Male fetal gender is associated with an overall increased risk of pre-eclampsia. However, it was recently shown that the male: female birth ratio was decreased in pre-eclampsia associated with preterm delivery. The reason for this discrepancy is not known. Objective. To investigate whether the fetal and newborn gender is associated with the incidence of antenatal maternal pregnancy com
