摘要:Abstract(#br)A novel indirect substitution spectrophotometric methodology using porphyrin is developed for the determination of some metals that do not react with porphyrin directly. The methodology is concerned with a multistep reaction system, which consists of 3 complexat...

摘要:Abstract(#br)A kinetic method for the determination of cysteine on flow injection system is described. Cysteine was found as a catalyst for the complexation reaction of Cu(II) with an ultra sensitive colorimetric reagent of 5,10,15,20-tetrakis (4- N -trimethylammino-phenyl) ...

摘要:Abstract(#br)The preparation of Li y Mn x Ni 1− x O 2 from LiOH·H 2 O, Ni(OH) 2 and γ -MnOOH under oxygen and flowing air is studied. Single phases of Li y Mn x Ni 1− x O 2 (0< x <0.3 in O 2 , 0< x <0.2 in air) are prepared by using γ -MnOOH as a manganese source. The o...

摘要:Abstract(#br)We isolated flattened shoot meristem ( fsm ) mutants in rice that showed defective seedling growth and died in the vegetative phase. Since most fsm plants had flat and small shoot apical meristems (SAMs), we suggest that FSM is required for proper SAM maintenance. FS...

摘要:Abstract(#br)The preparation of LiCo y Mn x Ni 1− x − y O 2 from LiOH·H 2 O, Ni(OH) 2 and γ-MnOOH in air was studied in detail. Single-phase LiCo y Mn x Ni 1− x − y O 2 (0≦ y ≦0.3 and x =0.2) is obtained by heating at 830–900°C. The optimum heating temperature...

摘要:Abstract(#br)A kinetic method performed on a flow injection system is described for the determination of ascorbic acid by using its catalytic effect on the complexation reaction of Cu(II) with 5,10,15,20-tetrakis(4- N -trimethyl-aminophenyl)porphyrin. The characteristic spec...

摘要:Abstract(#br)Since a tokamak fusion reactor will require a fast response and precise power supply to control the coil current, we propose a matrix converter configuration, as a candidate, having a filter in a load side and smaller elements than a conventional matrix converte...

摘要:Abstract(#br)The adaxial–abaxial axis in leaf primordia is thought to be established first and is necessary for the expansion of the leaf lamina along the mediolateral axis. To understand axis information in leaf development, we isolated the adaxialized leaf1 ( adl1 ) mutant...

摘要:RNA silencing is a defense system against "genomic parasites" such as transposable elements (TE), which are potentially harmful to host genomes. In plants, transcripts from TEs induce production of double-stranded RNAs (dsRNAs) and are processed into small RNAs (small interfering...

摘要:Abstract(#br) Background(#br)The rice PLASTOCHRON ( PLA ) genes PLA1 and PLA2 regulate leaf maturation and the temporal pattern of leaf initiation. Although the function of PLA genes in the leaf initiation process has been analyzed, little is known about how they affect leaf grow...
