The impact of coherent light propagation on the excitation and fluorescence of thorium nuclei in a crystal lattice environment is investigated theoretically. We find that in the forward direction, the fluorescence signal exhibits characteristic intensity modulations dominated by a sped-up initial decay signal that is orders of magnitude faster. This feature can be exploited for the optical dete...

Thorium is a naturally occurring radioactive element that has been identified as potential alternative fuel for nuclear energy production. Additionally, thorium-based reactors have inherent safety features reduce the risk of accidents and proliferation. As result, there growing interest in development viable to fossil fuels. This paper looks at present status thorium technology, providing an ov...

The requirements on a neutral current additive tc the heavy water in the SNO project are as follows: water solubility, low inherent radioactivity or the availability of an easy path of purification from thorium and radium, the possibility for easy separation from the water phase and safety. The solution of such an additive is expected to be transparent in the visible range, stable for extended ...

IR, X-ray diffraction and thermal analysis were used to illustrate the structure of cerium and thorium laurate in solid state. IR results reveal that the fatty acid exists with dimeric structure through intermolecular hydrogen bonding and cerium and thorium laurate were ionic in nature. The X-Ray diffraction measurements confirm that these soaps posses double layer structure with long spacing. ...

conclusions the combination of intravenous paracetamol 1 gr and ketamine 0.5 mg/kg resulted in an overall reduction in pain scores, decreased postoperative analgesic requirements, and lower agitation score compared with intravenous paracetamol 1 gr and tramadol 0.7 mg/kg for patients undergoing renal surgery. results postoperative pain scores were significantly lower in the pk group than in the...
