The main features of the ultraviolet spectrum of acrolein have been studied by a multireference perturbative treatment and by a time dependent density functional approach. The valence and Rydberg transition energies have been calculated and the assignment of the experimental bands has been clarified. The different relaxation trends of the three lowest singlet and triplet excited states have been a
According to Swedish legislation (LVM) compulsory treatment shall be decided on if someone, due to ongoing abuse of alcohol, drugs or volatile solvents, is in need of care to overcome abuse and if a voluntary intervention is not possible. Very little research has been conducted in Sweden on this particular legislation with regard to the clients' experiences of entire process from assessment to aft
An outcrop consisting of a 608 Myr old sheeted dyke complex and dyke-intruded metasediments has been investigated palaeomagnetically. It is located in the interior of a nappe the basal and upper parts of which suffered penetrative deformation and amphibolite grade metamorphism during the Caledonian orogeny. The only trace from the orogeny at the outcrop is a widely spaced network of brittle and du
The greater sensitivity of magnetic resonance spectroscopy (MRS) compared with MRI to brain abnormalities in Rasmussen's encephalitis was demonstrated in a 3-year-old boy. The patient, with symptoms, signs and morphological findings consistent with Rasmussen's encephalitis, was followed with MRI and MRS over 30 months. That metabolic changes can be disclosed by MRS before the development of sympto
Ecological and evolutionary change is generated by variation in individual performance. Biologists have consequently long been interested in decomposing change measured at the population level into contributions from individuals, the traits they express and the alleles they carry. We present a novel method of estimating individual contributions to population growth and changes in distributions of
This paper presents a study of the pre-history and evolution of a regional innovation system initiative supporting activities at the intersection of traditional food production and modern biotechnology. Drawing on established ideas on the triple helix of industry, university and government and its impact on innovative capacity (as they are formulated in the regional innovation systems approach) an
Four flavonols with spasmolytic activity have been isolated from a methanol extract of Artemisia abrotanum L. (Asteraceae), as the principles primarily responsible for the smooth muscle relaxing activity of this plant. The flavonols show a dose-dependent relaxing effect on the carbacholine-induced contraction of guinea-pig trachea, the EC50 values for compounds 1-3 are 20-30 mumol/l while compound
Anesthetized, paralyzed and mechanically ventilated pigs were hypoventilated to extreme hypercapnia (PaCO2 approximately 20 kPa) at FiO2 0.5, and allotted to a hypothermic group (31.5 +/- 0.1 degrees C, n = 6) or a control group (39.6 +/- 0.2 degrees C, n = 6). Compared with the controls, the hypothermic animals had higher PaO2 (19.2 vs 15.6 kPa, P < 0.05), SaO2 (97.2 vs 89.3%), SvO2 (78.7 vs 68.2
Articulated polychaete jaw apparatuses and scolecodonts from the uppermost Llandovery-lower Wenlock Ireviken Event strata of Gotland, Sweden, are illustrated and discussed and one new species, Kalloprion kilmisteri, that disappears at datum 2 of the Ireviken Event is described.
Objectives: To compare a laparoscopic (totally extraperitoneal patch (TEP)) and an open technique (Lichtenstein) for inguinal hernia repair regarding recurrence rate and possible risk factors for recurrence. Summary Background Data: Laparoscopic hernia repair has been introduced as an alternative to open repair. Short-term follow-tip suggests benefits for those patients operated with a laparoscopi
A prospective, randomized study comparing the compression hip screw with the Gamma nail in the treatment of 426 intertrochanteric fractures is reported. The median patient age was 80 years, and 71 % were women The compression hip screw operation took less time except in Evans Type 5 fractures. Blood loss generally was less in the compression hip screw group except in patients with Type 5 fractures
Neutron-rich, radioactive Zn isotopes were investigated at the Radioactive Ion Beam facility REX-ISOLDE (CERN) using low-energy Coulomb excitation. The energy of the 2(1)(+) state in Zn-78 could be firmly established and for the first time the 2(+)-> 0(1)(+) transition in Zn-80 was observed at 1492(1) keV. B(E2,2(1)(+)-> 0(1)(+)) values were extracted for Zn-74,Zn-76,Zn-78,Zn-80 and compared to la
To reduce the examination time for dark adaptometry, which including preadaptometry normally takes 30 minutes for an eye, a computerized adaptometer was constructed allowing monocular examination of both eyes simultaneously. The total examination time was thereby reduced from 60 to 30 minutes. This improvement was achieved by the use of electronically monitored transparent shutters that were alter
We investigate vascular changes during Photodynamic therapy (PDT) of skin tumors using optical Doppler tomography (ODT). The effect of vascular shut down on tumor destruction is currently not known, and to optimize treatment it is relevant to investigate this issue further. Optical Doppler tomography is capable of measuring blood flow in biological tissue down to 1-2 mm with sub-mm/s velocity sens
Tumour angiogenesis and the levels of plasminogen activator inhibitor type I (PAI-I) are both informative prognostic markers in breast cancer. In cell cultures and in animal model systems, PAI-I has a proangiogenic effect. To evaluate the interrelationship of angiogenesis and the PAI-I level in breast cancer, we have evaluated the prognostic value of those factors in a total of 228 patients with p
