Metal complexes containing natural and and artificial radioactive elements and their applications.
Recent advances (during the 2007-2014 period) in the coordination and organometallic chemistry of compounds containing natural and artificially prepared radionuclides (actinides and technetium), are reviewed. Radioactive isotopes of naturally stable elements are not included for discussion in this work. Actinide and technetium complexes with O-, N-, N,O, N,S-, P-containing ligands, as well π-or...
متن کاملStratospheric tracer modeling key aspects
This study describes key aspects of global chemistry-transport models and the impact on stratospheric tracer transport. We concentrate on global models that use assimilated winds from numerical weather predictions, but the results also apply to tracer transport in general circulation models. We examined grid resolution, numerical diffu-5 sion and dispersion of the winds fields, the meteorology ...
متن کاملCerebral circulation after cardiac arrest. Microangiographic and protein tracer studies.
The effects of ventricular fibrillation and subsequent resuscitation on the microcirculation of the verebral cortex were studied with microangiographic and fluorescent protein tracer techniques. Immediately after revival, a transient period of impaired cerebral perfusion occurred before complete recovery from circulatory arrest was obtained. A circulatory arrest of longer than ten minutes, foll...
متن کاملA Study of Tracer Transports by Planetary Scale Waves in the Mit Stratospheric General Circulation Model
The quasi-geostrophic global stratospheric model at MIT developed by is used to study the zonal and time-averaged transport of potential temperature and ozone by the planetary zonal wavenumbers 1-6. Several types of covariances between the winds, geopotential, and the tracers are calculated in order to evaluate the directions and strength of the fluxes and the winds causing the fluxes. The eddy...
متن کاملRadioactive iodine and radioactive cesium: two important radio-hazard elements in post nuclear power plant crisis
The present nuclear leakage crisis from Japan is a topic to be discussed in present public health. In radiology, the leaked radioactive elements are considered hazard. Here, the author briefly reviews and discusses on two important radio-hazard elements in post nuclear power plant crisis, radioactive iodine and radioactive cesium. Based on previous similar nuclear crisis in Russia, it ...
