Opis:: A new tritium extraction system composed of a trickle-bed hydrogen/water isotopic exchange column using a hydrophobic Pt-catalyst combined with an SPE-water electrolyser (EXEL-process) and a thermal diffusion column cascade was proposed for the removal of tritium from heavy water irradiated in HMR ((Heavy Water Moderated Power Reactor), volume of heavy water = 140 m3 and mean neutron flux = 5×1013 n/cm2s). Numerical study on the extraction of tritium from the heavy water was carried out and the dimensions of proposed system were determined under the conditions that the concentration of tritium in the heavy water was kept less than 2.5 Ci/lHW. The calculation results indicated that the proposed system was designed practically.

Tytuł:: A rare case of severe cognitive impairment which prolonged after first lacunar infarct in right internal capsule

Opis:: Lacunar infarcts have been defined as small lesions within a diameter of 1.5 centimeters causing mild symptoms. However, we treated a patient showing prolonged, severe disturbance of the cognitive function after a lacunar infarct. The 85-year–old woman was found lying on the floor of her house, and she was transported to our hospital. Computed tomography (CT) revealed a right lacunar infarct, and magnetic resonance imaging (MRI) showed severe periventricular hyperintensity (PVH) of her brain. Her severe consciousness disorder showed improvement, but severe cognitive impairment including disorientation remained when she was transferred to another hospital. These findings suggested that the reserve capacity of her brain was minimal. The addition of a lacunar infarct to a severe situation like this might induce severe cognitive impairment.

Opis:: We found the easy and efficient synthesis method of the vertically aligned ultralong multi-walled nanotubes using iron chloride powder. The 2.1-mm-long bulk nanotubes can be grown by conventional thermal chemical vapor deposition on bare quartz surface with the single gas flow of acetylene for 20 min. In addition to the high growth rate, the bulk of carbon nanotubes is easily spun into the yarn by pulling it out, and the present method also provides the coating ability with nanotubes as a new functionality of this nanomaterial.
