Increasing the yield is one of the most important goals of crop *** the beginning of rice cultivation thousands of years ago,many efforts have been made to increase rice *** of the successes in this history was the Green *** tremendous improvement in the 1960s was achieved by increasing rice and wheat production through the development and widespread adoption of semi-dwarf varieties with the extensive use of fertilizers(Hedden,2003).Dwarfism in crops lowers the center of gravity of the plant body,reducing the risk of lodging and enabling farmers to use more fertilizer to increase ***-dwarf mutations in both rice and wheat created during the Green Revolution are related to the plant growth hormone gibberellin(GA).Although other mechanisms cause dwarf mutants,only GA-related semi-dwarf mutants were selected during the Green Revolution(Wang et al.,2021).While GA-related abnormalities only make plants shorter,most cases caused by other mechanisms involve not only dwarfism but also other morphological abnormalities.

The Yoshii Group of the Akiyoshi terrane is distributed over the Otakeyama area, Okayama Prefecture, southwest Japan. The Yoshii Group is composed of siliceous rocks and clastics, comprising chert-clastic sequences. The Yoshii Group is divided into four structural units （Units Ot 1, Ot 2, Ot 3, and Ot 4） in structurally ascending order. Lithological similarities and radiolarian age suggest that these units exhibit almost identical ocean plate stratigraphy. These units are structurally-repeated to form an imbricate structure. This structure was possibly formed by off-scrape accretion at a toe of an accretionary complex. Additionally, a review of previous studies indicates that an imbricate structure is common in the Akiyoshi terrane. The presence of an imbricate structure in the Akiyoshi terrane, Permian accretionary complex, indicates the possibility that a specific horizon of Permian pelagic sequences acted as a drcollement zone.

Barium titanate （BaTiO3） and strontium titanate （SrTiO3） nanoparticles were synthesized separately through hydrothermal reaction of crystalline TiO2 particles and corresponding alkaline earth hydroxides, Ba（OH）2 and St（OH）2 respectively, in 50 mol·dm^-3 KOH solution at 150℃. Each structural evolution of BaTiO3 and SrTiO3 during the hydrothermal treatment was investigated by X-ray diffraction （XRD）, field emission scanning electron microscopy （FE-SEM）, field emission transmission electron microscopy （FE-TEM） and thermogravimetry- differential analysis （TG-DTA）. In the BaTiO3 system, round particles with cubic perovskite-type structure were obtained within 1 h. However, these particles were gradually dissolved and then were re-precipitated in the form of cube-shape BaTiO3 particles with a smaller lattice constant ac than that of the former phase. After the BaTiO3 particles formed firstly have disappeared completely, or the two phases coexistence stage with different lattice constant ac passed, lattice constant ac of BaTiO3 phase re-precipitated continuously decreased with annealing time. In contrast, once SrTiO3 particles are formed, the lattice constant ac decreased continuously throughout the reaction. The result indicates that SrTiO3 particles were annealed without dissolution and precipitation process under the present condition.

Cold spray is a technique to make a coating on a wide variety of mechanical or electric parts by spraying solid particles accelerated through a high-speed gas flow in a converging-diverging nozzle. In this study, pseudo-shock waves in a modeled cold spray nozzle as well as high-speed gas jets are visualized by schlieren technique. The schlieren photographs reveals the supersonic flow with shock train in the nozzle. Static pressure along the barrel wall is also measured. The location of the head of pseudo-shock wave and its pressure distribution along the nozzle wall are analytically explained by using a formula of pseudo-shock wave. The analytical results show that the supersonic flow accompanying shock wave in the nozzle should be treated as pseudo-shock wave instead of normal shock wave.
