The mechanistic aspects of the electrochemical reduction of U(V1) nitrate at a mercury electrode in chloroform, using three different supporting electrolytes, are described. In the presence of tetrabutylarnmonium perchlorate (TBAP) as a neutral electrolyte, UO (NO ) , reduced in two irreversible electrochemical steps to form a U(V1)-U(V) binuclear complex and U(IV), respectively. In the pr...

We show that information in quantum memory can be erased and recovered perfectly if it is necessary. That the final states of environment are completely determined by the initial states of the system allows that an easure operation can be realized by a swap operation between system and an ancilla. Therefore, the erased information can be recoverd. When there is an irreversible process, e.g. an ...

We examine the concentration invariance of cyclic species for the irreversible polymerization. The simulation results show that the invariance holds in good approximation in the irreversible process also. The validity of the simulation equations employed was confirmed through comparison with the recent experimental observations by the Nagoya university group carried out independently of the pre...

Generally, polymers can be classified according to their thermal and mechanical properties into thermoplastics, thermosets and elastomers. Thermoplastics are amorphous or semicrystalline polymers that soft or melt during heating and solidify during cooling. The heating/cooling/heating process can be repeated without perceptible changes in thermal and mechanical properties of thermoplastics. The...

Assessment of neurological and psychiatric disorders like depression are unusual from a speech processing perspective, in that speakers can be prompted or instructed in what they should say (e.g. as part of a clinical assessment). Despite prior speech-based depression studies that have used a variety of speech elicitation methods, there has been little evaluation of the best elicitation mode. O...

the presence of immune factors in inflamed dental pulps, suggests that immune responses could participate in disease process. with regard to the presence of significant number of mast cells in pulpitis cases, the purpose of this study was to determine the correlation between concentration and presence of ige in supernatant fluids of explants cultures of different states of dental pulps. for thi...
