Radiative lifetime measurements were performed with time-resolved laser-induced fluorescence techniques for 47 levels of the astrophysically important ion Sm1+ over the energy range 21000-36 000 cm(-1). The new results have been compared with previous measurements but also with theoretical calculations taking configuration interactions and core-polarization effects into account, and a satisfying a

In this thesis we study the critical Ginzburg-Landau action, defined on fields in the plane which are allowed to have a finite number of singularities. We show that a topological invariant, the degree, can be defined under the assumption of finite action only. The action is bounded below by a constant times the degree, and the fields which realize this lower bound satisfy a first order differentia

Artikeln undersöker det för rätten fundamentala begreppet "tiden". Utgångspunkt är president George W. Bushs krig mot krig mot terrorismen - the War on Terrorism - med exempel från invasionen och den påföljande ockupationen av Irak. Artikeln argumenterar för en eskatologisk förståelse av rätten under the War on Terrorism, något som förskjuter tidens perspektiv, och som påvisar ett undantagstillstå

A method for determining hexahydrophthalic (HHP acid) and methylhexahydrophthalic acids (MHHP acid) from human urine was developed. These acids are metabolites of the highly sensitising hexahydrophthalic anhydride and methylhexahydrophthalic anhydride. The acids were purified from urine by liquid-solid extraction and derivatised with pentafluorobenzyl bromide to the corresponding esters. These wer

Popular Abstract in Swedish Redan för 5000 år sedan i det antika Egypten användes ljus för att behandla vissa hudåkommor. Denna bortglömda kunskap återupptäcktes i början av förra seklet men fick inget riktigt genomslag. De senare årtiondenas framsteg inom kemi och fysik har återigen gjort ljusbehandling av sjukdomar högintressant. Speciellt upptäckten av lasern på 1960-talet har gjort att tillämpSince cancer continues to plague humanity there is large need for development of modalities for both diagnosis and therapy. Most of the currently available methods suffer from serious disadvantages. The treatments, e.g. ionising radiation, chemotherapy, surgery, may themselves induce malignancies or the patient may be physically impaired for a longer period of time. The work presented aims at dev

Background Studies on blood flow velocity in the fetal middle cerebral artery have revealed signs of brain sparing in chronic hypoxia. These signs of brain sparing can disappear in the terminal case, but whether this applies to the whole brain or only parts of it is unknown. Methods Velocity waveforms of the middle cerebral, anterior cerebral and posterior cerebral arteries were recorded in 221 pr

The study aimed to estimate the relative dose potency of salbutamol inhaled via Turbuhaler and Diskhaler. The 24 adult patients participating had chronic reversible airway obstruction. The study was of a double-blind, double-dummy, crossover, randomized design. Five doses of salbutamol Turbuhaler, 50, 50, 100, 200, and 400 microg, were given on one study day at intervals of 30 min. On another stud

Insertion of lithium in anatase TiO2, giving LixTiO2, is performed under ultrahigh vacuum (UHV) conditions and studied using synchrotron radiation based electron spectroscopy. Core level photoemission spectra are directly compared to results obtained after electrochemical insertion, illustrating the usefulness of the UHV approach. The growth of a state of mainly Ti 3d character in the band gap is

Stress management was studied in male patients with solvent-induced chronic toxic encephalopathy (TE) of types 2A (TE 2A, n = 31) and 2B (TE 2B, n = 26). The patients were compared with a healthy reference group (n = 57). Self-reported symptoms (90-item Symptoms Checklist [SCL-90]), sense of coherence, coping strategies, and level of mastery were measured. As expected, both TE groups reported high

ATP-sensitive K(+) channels (K(ATP) channels) of pancreatic beta-cells play key roles in glucose-stimulated insulin secretion by linking metabolic signals to cell excitability. Membrane phosphoinositides, in particular phosphatidylinositol 4,5-bisphosphates (PIP(2)), stimulate K(ATP) channels and decrease channel sensitivity to ATP inhibition; as such, they have been postulated as critical regulat

Pyridoxine-dependent seizures are rare in newborn infants, although recent data suggest that the prevalence probably is underestimated. In all newborn infants with recurrent epileptic seizures the general recommendation is to administer pyridoxine and simultaneously record an electroencephalogram (EEG). Conclusion: One infant with pyridoxine-responsive seizures and another with pyridoxine-dependen

1 We model the potential vegetation and annual net primary production (NPP) of China on a 10' grid under the present climate using the processed-based equilibrium terrestrial biosphere model BIOME3. The simulated distribution of the vegetation was in general in good agreement with the potential natural vegetation based on a numerical comparison between the two maps using the DeltaV statistic (Delt
