Laser spectroscopy of the C1Σ+-X1Σ+ transition of ScBr

The laser induced fluorescence spectrum of scandium monobromide (ScBr) between 795 and 845 nm has been recorded and analyzed. ScBr was produced by reacting laser vaporized Sc atoms with ethyl bromide (C 2H 5Br). Spectra of six vibrational bands of both Sc 79Br and Sc 81Br isotopomers of the C 1Σ +-X 1Σ + transition were observed. A least-squares fit of the measured line positions yielded accurate molecular constants for the v = 0-3 levels of the C 1Σ + state and the v = 0-2 levels of the X 1Σ + state. The equilibrium bond length of the C 1Σ + state has been determined to be 2.4776 . © 2012 Elsevier B.V. All rights reserved.postprin

Laser Induced Fluorescence Spectroscopy Of Scandium Monoiodide

Oral PresentationSession: RA ElectronicThe laser induced fluorescence spectrum of scandium monoiodide (ScI) between 787 and 814 nm has been recorded. ScI molecule was produced by reacting laser vaporized Sc atoms with methyl iodide (CH3I). Spectra of eleven vibrational bands of the C1Σ + - X1Σ + transition of ScI were obtained and analyzed. A merged least-squares fit of the measured line positions yielded accurate molecular constants for the upper levels of the C1Σ + state and the v = 1 - 4 levels of the X1Σ +state. One vibrational band observed at 11627 cm−1 belongs to a sub-band transition of the a3∆ state, which is found to be perturbed by the X1Σ + state. Details of the perturbation and molecular constants obtained will be reported.published_or_final_versio

A synopsis of current haemophilia care in Hong Kong

Objective To provide a synopsis of current haemophilia care in Hong Kong. Design Retrospective survey. Setting All haematology units of the Hospital Authority in Hong Kong. Patients All patients with haemophilia A and haemophilia B. Results To date, there were 222 mild-to-severe haemophilia patients (192 type A, 30 type B) under regular public care in Hong Kong (43% were considered severe, 33% moderate, and 24% mild), which gave a crude prevalence of 6.8/100 000 male inhabitants. A total of 12.8 million units of Factor VIII and 3 million units of Factor IX were prescribed annually. This amounts to 1.83 units of FVIII per capita of the population, which is comparable to that of other developed countries. Leading causes of mortality were human immunodefciency virus-related complications (10 cases) and cerebral bleeding (2 cases). The life expectancy of patients with severe haemophilia in Hong Kong is improving; currently the oldest patient is 60 years old. Such improved survival may be due to enhanced factor availability, prompt treatment of bleeding episodes at home, safer factor products, and better antiviral treatment. Primary prophylaxis is the accepted standard of care for severe and moderate cases, and "Factor First" has become hospital policy. However, 12 patients continue to present treatment challenges, due to the documented presence of factor inhibitors. In all, 28,100, and 14 cases respectively were positive for human immunodefciency virus, hepatitis C virus, and hepatitis B virus; the youngest patients with the corresponding infections being 28,13, and 22 years old. Comprehensive care with dedicated physiotherapy, surgical support, and radionucleotide synovectomy may reduce morbidity further. Conclusion A multidisciplinary approach can further improve the future care for haemophilia patients in Hong Kong.published_or_final_versio
