The title compound, [Pt2Cl2(C6H5)2(C2H6OS)2] or [Pt([bold mu]-Cl)Ph(dmso)]2 (dmso is dimethyl sulfoxide), is a dimer with a pseudo square-planar coordination geometry around the Pt atoms, with two bridging Cl ligands creating a four-membered ring at the centre of the dimer. The complex is centrosymmetric, thus necessitating a trans configuration, with one dmso and one phenyl ligand coordinated to
Natural lifetimes of some highly excited levels in the Pb-I spectrum have been measured by the zero field level crossing (Hanle) method. The levels were reached by optical excitation from the metastable 6p2 3P2 and 6p2 3P1 states, were a considerable population had been created by means of adc discharge in a Pb atomic beam. An atomic beam source producing atoms in metastable states is described. F
Our previous studies indicated that acute haemorrhage leads to a pronounced increase in the release of endothelium-derived nitric oxide (EDNO) graded in relation to the magnitude of the blood loss. The EDNO-induced vasodilatation, confined selectively to the arterial 'feeder' vessels, attenuates the concomitant reflex adrenergic constriction and thereby prevents deleterious reduction of blood flow
Optical data storage devices and erasable memories with storage densities in the range of terabits/cm2, all-optical devices for communication like optical bit-rate converters, routers and image processors can become a reality with photon-echo-based frequency-selective materials. In photon-echo-based optical data storage and data processing the photon-echo-output intensity generally is about 0.1–1%
Modified ultrafiltration (MUF) is often used in conjunction with paediatric cardiac surgery with cardiopulmonary bypass (CPB) and is thought to improve clinical outcome. It is unclear whether these improvements (if any) are due to the removal of inflammatory mediators. In this prospective study, 18 children aged 12-24 months undergoing uncomplicated cardiac surgery with methylprednisolone added in
For the last many decades industry and insurance companies have been interested in protecting high racked goods from rapid fire growth. This has mainly been done by installing sprinklers of various types and designs in order to either extinguish the fire or control it. The efficiency of such protection measures is, however, very much dependant on the geometry of the stacks, their height, floor are
The deactivation of a commercial selective catalytic reduction (SCR) catalyst of type V2O5−WO3/TiO2 has been studied in this work through comparisons of results from a full-scale biomass combustion plant with those from laboratory experiments. In the latter, the catalyst was exposed to KCl, K2SO4, and ZnCl2 by both wet impregnation with diluted salt solutions and deposition of generated submicrome
Wobbling is a rotational mode unique to a triaxial body. The Lu-Hf isotopes with N similar to 94 at high spin provide a possible region of nuclei with pronounced triaxiality. We have investigated Lu-163 through the fusion-evaporation reaction La-139(Si-29,5n)Lu-163 with a beam energy of 152 MeV. Three excited bands decaying into the known, presumably triaxial, superdeformed (TSD) band built on the
The purpose of this PhD thesis work has been to develop optical techniques that can help utility engineers for assessing the state of insulators in service and in a laboratory. The possibilities to use remote laser induced fluorescence for detection and imaging of biological growth such as algae and fungi have been investigated. Reflectance spectroscopy has also been investigated as a technique fo
The resection of the ulnar head, as described by Darrach, has unfortunately become the standard of care despite the frequent problems of ulnar stump instability following this procedure. To offer better treatment to our patients, we have to appreciate the various roles and the importance of the ulnar head for the function of the distal radioulnar joint (DRUJ) in mechanically loaded forearm rotatio
Popular Abstract in SwedishAvhandlingens syfte var att öka kunskapen om syskons och föräldrars erfarenheter av barn med autism och utvecklingsstörning, vad som ledde fram till beslutet att söka en plats i en gruppbostad för sitt barn och vad det innebar för föräldrar att deras barn flyttat. Avsikten var också att öka kunskapen om personalens erfarenheter av arbetet i en gruppbostad för barn med auThe aim of this dissertation was to gain knowledge about the experiences of siblings and parents of children with autism and learning difficulties, about what brought about the decision to apply for a place in a group home for their child and what it meant for the parents that their child had moved. A further aim was to gain knowledge about what it is like to work in a group home for children with
High-order harmonics generated through the interaction of atoms and strong laser fields are a versatile, laboratory-scale source of extreme ultraviolet (XUV) radiation on a femtosecond or even attosecond time-scale. In order to be a useful experimental tool, however, this radiation has to be well characterized, both temporally and spectrally. In this paper we discuss how multi-photon, multi-colour
Radiative lifetime measurements have been performed, with a time-resolved laser-induced fluorescence technique, for 12 levels of Os I and for 9 levels of Os II. For 9 levels of Os I and 4 levels of Os II, there were no previous experimental data available. From a comparison with new theoretical calculations, taking configuration interactions and core-polarization effects into account, it has been
