This paper deals with the applicability of Robust Adaptive Control to the attitude motion control of large spacecraft. Large spacecraft and space structures, such as large communication satellites and the ISS (International Space Station), have been

Our recent studies seem to indicate that annulenoannulenes consisting of two same size nuclei should be fused systems of two diatropic moieties. In order to obtain further information on the nature of annulenoannulene, the synthesis of dibenzo- and b

The radiation chemical characteristics of DNA-related compounds, especially thymine, as the most radiosensitivity DNA base in aqueous solution, are shown to obtain correlations with the radiation inactivations of bacterial and mammalian cultured cell

Remarkable promation of the hydroxylation of thimine to give thimine glycol with almost complete depression of side reactions by 2,2,6,6-tetramethylpiperidine-1-oxyl (TMPO·) derivatives was observed in the γ-radiolyses of the N2- and N2O-saturated

Thymine in aqueous solution was decomposed with quantum yields of 0.3 and 0.4 under N2-saturated and aerated conditions by far-ultraviolet light (> 180 nm, far-uv), and quantum yields of 2 × 10−4 and 3 × 10−4 by near-ultraviolet light (> 220 nm

Increase of diatropicity of the dibenzotrisdehydro[14]annuleno[14]annulene as compared with that of benzotrisdehydro[14]annuleno[14]annulene, which is expected if the dibenzannulenoannulene is a peripheral conjugated system could not be observed. The

Tetrakisdehydro[16]annuleno consisting of trisdehydro[16]annulene and bisdehydro[18] annulene has been synthesized. Induction of para- and diamagnetic ring currents in 16- and 18-membered rings, respectively, was clearly recognized by the 1H NMR spec

A series of 3-nitro-1,2,4-triazole derivatives bearing various types of side chain (R) at the N1-position (AK-2000 series) were synthesized and their radiosensitizing effect and toxicity in vitro and in vivo were investigated, in comparison with thos
