Visible-UV fluorescence emission of gas-phase hydrogen sulfide, H(2)S, has been studied at the S 2p edge with synchrotron radiation excitation. Dispersed fluorescence measurements in the wavelength range 300-900 nm were taken at several photon energies corresponding to the excitations of the S 2p electrons to the unoccupied molecular and Rydberg orbitals. The spectra reveal fluorescence from the H
In the present article we give a general three-dimensional formalism for scattering in two half spaces, one of which contains a bounded inhomogeneity. Our formalism consists of an extension of the transition matrix method which has been given by Waterman, a method which applies equally well to acoustic, electromagnetic, and elastic scattering. The formalism is here developed in detail for the case

Positron emission tomography combined with computed tomography (PET/CT) is a quantitative technique suitable for diagnostics and uptake measurements. The quantitative results can be used for the purpose of the calculating absorbed dose to patients undergoing nuclear medicine investigations. Hence, the accuracy of the quantification of the activity content in organs or tissues is of great importanc
Rapid developments in preoperative noninvasive imaging as well as advanced endovascular techniques have made endovascular treatment of acute arterial mesenteric ischemia a feasible treatment option in many patients. Multidetector computed tomographic angiography will provide the diagnosis and guide treatment in most cases. The use of mechanical and aspiration embolectomy, sometimes in combination
Cervical cancer remains a leading cause of morbidity and mortality in Uganda. Despite earlier information campaigns to introduce human papilloma virus (HPV) vaccination, which also targeted cervical cancer, misinterpretation and misunderstanding of the subject remain high. Women in Uganda present with cervical cancer at an advanced stage due to poor health-seeking behaviours, with an associated hi
The length of stay in hospital following total knee replacement is markedly shortened due to fast-track programmes. Patients have to be responsible for their recovery at a very early stage. The aim of this study was to investigate the prevalence of physical health problems and the level of exercising in the early recovery period after discharge from hospital following total knee replacement.
Cerebral ischemia remains a major cause of morbidity and mortality with little advancement in subacute treatment options. This review aims to cover and discuss novel insight obtained during the last decade into plastic changes in the vasoconstrictor receptor profiles of cerebral arteries and microvessels that takes place after different types of stroke. Receptors like the endothelin type B, angiot
Chondroitin/dermatan sulfate is a highly complex linear polysaccharide ubiquitously found in the extracellular matrix and at the cell surface. Several of its functions, such as binding to growth factors, are mediated by domains composed of alternating iduronic acid and 4-O-sulfated N-acetylgalactosamine residues, named 4-O-sulfated iduronic acid blocks. These domains are generated by the action of
The use of this material under current use conditions is supported by the existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity, skin sensitization potential, as well as, environmental safety. Reproductive toxicity was based on the Threshold of Toxicological Concern (TTC)
This dissertation is a contribution to the knowledge of the computational complexity of discrete combinatorial problems. 1. The first problem that we consider is to compute the maximum independent set of a box graph, that is, given a set of orthogonal boxes in the plane compute the largest subset such that no boxes in the subset overlap. We provide an $mathtt{exp}(O(sqrt nlog n))$-time algorithm
