1 Non-adrenergic, non-cholinergic (NANC) relaxations induced by electrical field stimulation (EFS)were studied in pig isolated urethra. The mechanism for relaxation was characterized by measurement of cyclic nucleotides and by study of involvement of different subsets of voltage-operated calcium channels (VOCCs). 2 EFS evoked frequency-dependent and tetrodotoxin-sensitive relaxations in the prese
Radiative lifetimes of 30 excited states of Er 11, ranging in energy from 25 592 to 36 148 cm(-1), have been measured by means of a time-resolved laser-induced fluorescence (LIF) technique. Free, singly ionized erbium ions were produced in a laser-induced plasma. A tunable laser, with 1 ns duration pulse, was employed to selectively excite the Er+ ions. The lifetime values were evaluated from the
Analyzing a free boundary problem for harmonic functions we show that there are no closed particle paths in an irrotational inviscid traveling wave propagating at the surface of water over a flat bed: within a period each particle experiences a backward-forward motion with a slight forward drift.
We describe adaptation of ballistic imaging for the liquid core of an atomizing spray. To describe unambiguously the forces that act to break apart the liquid core in a spray, one must directly measure the force vectors themselves. It would be invaluable, therefore, to obtain velocity and acceleration data at the liquid-gas interface. We employ double-image ballistic imaging to extract velocity in
Electron analysis combined with ion mass spectrometry is shown to be a unique tool to understand fragmentation dynamics of core-excited molecules. This article describes in detail a new setup devoted to energy and angle correlations measurements between the emitted particles resulting from inner-shell ionization or excitation. The data collection system is based on a pair of position sensitive det
Background: Vitamin A supplementation (VAS) at birth has been associated with decreased mortality in Asia. Bacille Calmette-Guerin (BCG) vaccine is given at birth in tuberculosis-endemic countries. Previous studies suggest that VAS may influence the immune response to vaccines. Objective: Our objective was to examine whether VAS influences the immune response to simultaneously administered BCG vac
Background. It is well known that portacaval shunting ultimately leads to a decrease in liver volume and hepatic function, but the mechanism is uncertain. The aim of the present study was to evaluate the effect of portacaval shunting (PCS) upon the morphological changes that occur in the liver in rats after port caval. anastomosis. Materials and methods. Sixty-six male rats underwent either PCS (n
World-wide, the development of community-based geriatric rehabilitation has received increased attention. In Sweden, national reforms during the 1990s aimed at improved quality of geriatric rehabilitation. This paper focuses clients' perceptions of the rehabilitation process, dependence in activities of daily living (ADL), and subjective well-being in a one-year perspective. A study-specific quest
The beta -decays of the neutron-rich nuclei Be-12 and Ne-29 have been studied. The statistical correlations between the almost identical half-lives of Be-12 and its daughter B-12 are analysed for a large sample of Be-12 decay data. Stringent mutual bounds are obtained on the parameter set, leading to a precise determination of the Be-12 half-life of 21.50 +/- 0.04 ms. From a simultaneous detection
OBJECTIVE: To investigate signs of liver disease, and biochemical and immunological markers in blood donors with isolated GBV-C/HGV viremia. METHODS: Eighteen donors with isolated GBV-C/HGV viremia were followed up 3-5 years after initial identification. Testing for GBV-C/HGV RNA, GBV-C/HGV-E2 antibodies and a range of biochemical and immunological tests was performed. Thirteen donors consented to
The insertion of lithium in anatase TiO2 nanoparticles under ultrahigh vacuum (UHV) conditions is studied using x-ray absorption spectroscopy (XAS) and resonant photoelectron spectroscopy (RPES) at the Ti L-2,L-3 edge. It is demonstrated that XAS can be used to monitor the separation into an anatase phase and a lithium titanate phase of formal stoichiometry Li0.5TiO2. The initial state properties
As a model for redox components on the donor side of photosystem II (PS II) in green plants, a supramolecular complex 4 has been prepared. In this, a ruthenium(II) tris-bipyridyl complex which mimics the function of P680 in PS II, has been covalently linked to a tyrosine unit which bears two hydrogen-bonding substituents, dipicolylamine (dpa) ligands. Our aim is to mimic the interaction between ty
We report the observation of neutrons rf:leased from d(d,n) He-3 fusion reactions in the focus of 200 mJ, 160 fs Ti:sapphire laser pulses on a deuterated polyethylene target. Optimizing the fast electron and ion generation by applying a well-defined prepulse led to an average rate of 140 neutrons per shot. Furthermore, the production of a substantial number of MeV gamma rays could be observed. The
Popular Abstract in Swedish Sammanfattning: För religiösa sikher är Guru Granth Sahib en helig skrift som manifester ontologiskt gudomliga och förkroppsligar de historiska guruernas lära och uppenbarelseerfarenheter. Samtidigt har sikherna tagit uppfattningen om en helig skrift längre än någon annan religiös tradition genom att behandla Guru Granth Sahib som en levande guru med både andlig auktoriSummary: For religious Sikhs, the Guru Granth Sahib is a holy scripture which enshrines ontologically divine words and the teaching and revelatory experiences of historical human Gurus. Simultaneously the Sikhs have taken the concept of a sacred scripture much further than any other religious community by treating the Guru Granth Sahib as a living Guru invested with spiritual authority and agency
