The photoion excitation spectra of (NO)-N-14 and (NO)-N-15 have been studied in the 105-112 Mn excitation region using high-order harmonic laser spectroscopy. Utilizing the small bandwidth offered by this technique, the natural widths of prominent lines in this region have been measured. These lines originate from interactions between high-lying Rydberg levels converging to the NO+ electronic grou

Our aim was to study whether the in situ natural abundance N-15 (delta(15)N)-values and N concentration of understory plants were correlated with the form and amount of mineral N available in the soil. Also to determine whether such differences were related to earlier demonstrations of differences in biomass increase in the same species exposed to nutrient solutions with both NO3- and NH4+ or to N

Lifetimes on the sub-nanosecond scale for the levels v(2)D(3/2), v(2)F(3/2) and v(2)F(5/2) in the 4d5s5p configuration in Zr II have been measured, using the method of laser-induced fluorescence. Combined with branching fractions obtained with the Lund Ultraviolet (UV) Fourier Transform Spectrometer (FTS), experimental oscillator strengths have been derived. From Hubble Space Telescope/Goddard Hig

The natural radiative lifetime of the 3s 4p 1P1 level of neutral magnesium was measured by pulsed level-crossing spectroscopy at the short excitation wavelength of 202.6 nm. We obtained tau = 13.4(5) ns for this state, strongly deviating from a previous beam-foil result, but in good agreement with a multi-configuration Hartree-Fock calculation. A discussion of the applicability of the pulsed Hanle

Aims In a cohort of men and women with Type 1 diabetes, prospectively followed for > 20 years, vibrotactile sense in fingers was investigated and related to neurophysiological tests, glycaemic level and clinical score. Methods Out of 58 patients, diagnosed at the age of 15-25 years and recruited 1984-1985, 32 patients (13 women, median age 52 years, range 44-75 years; 19 men, median age 52 years,

This dissertation covers the issues related to credit risk that stem from the recent financial crisis and that are concerned by investors, financial intermediaries, and governments. The results of the research have important implications for asset managers, such as using the information from the credit risk market to rebalance stock portfolios, and for policy makers in regulating or bailing out ba

A historical review of the early development of Hartree-Fock and Multiconfiguration Hartree-Fock theories is presented. After the underlying theory is summarized, some recent results from the application of these methods to the prediction of atomic properties are described. These include total energies, transition probabilities, autoionization rates, specific mass shifts, and hyperfine parameters.

ABSTRACT: Study Design. The SRS brace study (JBJS-A, 1995) was comprised of patients with adolescent idiopathic scoliosis with moderate curve sizes (25-35°). Forty observed and 37 braced patients (77% of the original group) attended a follow-up a mean of 16 years after onset of maturity.Objectives. To analyze whether the subjectively evaluated present body appearance affects outcome as measured by

BACKGROUND: During myocardial infarction reduced blood flow in the heart muscle results in cell death. These dying/dead cells have been reported to bind several plasma proteins such as IgM and C-reactive protein (CRP). In the present study we investigated whether fluid-phase complement inhibitor C4b-binding protein (C4BP) would also bind to the infarcted heart tissue. METHODS AND FINDINGS: Initial

Object The calcium antagonist nimodipine has been shown to reduce the incidence of ischemic complications following aneurysmal subarachnoid hemorrhage (SAH). Although most randomized studies have been focused on the effect of the peroral administration of nimodipine, intravenous infusion is an alternative and the preferred mode of treatment in many centers. It is unknown whether the route of admin
