The effect of current density on the morphology of Zn electrodepositsprepared by a flow-channel cell was investigated by scanning electron microscopy (SEM). It was foundthat the morphology of Zn electrodeposits evolves from thin-layered hexagonal eta -phase crystalsto pyramidal eta -phase particles with increasing the current density. The morphological evolutionat various flow rates was also examined and the results show that the morphological evolution at alower flow rate is more remarkable than that at a higher flow rate with increasing the currentdensity. To reveal the mechanism of the morphological evolution in detail, the atomic configurationon both (0001)_eta and {1100 }_eta planes under different current densities was investigated, it wasnoted that a specify current density could provide a good condition for the layered epitaxialgrowth of hexagonal T)-phase.

Evolution of zinc morphology during continuous electrodeposition

Journal of University of Science and Technology Beijing 2003年第1期10卷 35-38页

作者： Ailing Fan M.kurosaki 等 DepartmentofMaterialsPhysicsandChemistry UniversityofScienceandTechnologyBeijingBeijing100083China SteelResearchLaboratoires NipponSteelCorporation20-1ShintomiFuttsuChiba-ken293

The morphology evolution of zinc continuous electrodeposits with nano-sized crystals on the ferrite substrate has been studied by in-situ scanning tunnel spectroscopy (STM). It is found that the morphology of zinc electrodeposits varies from initial granules with a size of about 30nm to layered platelets with increasing deposition time. Meanwhile, the crystal structure of the zinc electrodeposits is identified to be hexagonal η-phase by X-ray diffraction. The orientation relationship between zinc crystals and the substrate surface can be interpreted in terms of the misfit and the atomic correspondence of the interphase boundary between the η-phase deposits and α-Fe substrate.

Topographical and hydrological effects on meso-scale vegetation in desert steppe, Mongolia

Journal of Arid Land 2017年第1期9卷 132-142页

作者： Batdelger GANTSETSEG Masahide ISHIZUKA Yasunori kurosaki Masao MIKAMI Information and Research Institute of Meteorology Hydrology and Environment Ulaanbaatar 15160 Mongolia Faculty of Engineering Kagawa University Takamatsu 761-03 96 Japan Arid Land Research Center Tottori University Tottori 680-0001 Japan Japan Meteorological Business Support Center Tokyo 101-0054 Japan

This study investigated the seasonal variations of the normalized difference vegetation index（NDVI） and its relationships with climatic variables and topography in a small-scale（20 km×20 km） area（i.e., Tsogt-Ovoo village） within the desert steppe zone of Mongolia using in-situ observed climate data and satellite remote sensing data. We found that the topography is very important for vegetation growth in the desert steppe although the summer precipitation is the constraining factor. The unexpectedly high NDVI（up to 0.56）, as well as the high aboveground biomass, in the valley bottom was primarily resulted from the topography-modulated redistribution of overland flow after relatively heavy precipitation events during the growing season. This makes the valley bottoms in desert steppes not only reliable feeding resources for livestock but also heavens for wild lives. But, the detected large standard deviation of annual maximum NDVI（NDVI_（max）） from 2000 to 2013 in the valley bottom in response to rather variable precipitation implies that the valley bottoms under desert steppe climates are more vulnerable to climatic change.

Nano-sized growth of zinc electrodeposit on the ferrite substrate has been studied by means of in situ scanning tunnel microscopy (STM) and atomic force micoscopy (AFM). It is found that the morphology of zinc electrodeposit varies from initial about 30nm granular crystals to layered platelet crystals with increasing deposition time by using in situ STM. With AFM, the results show that the platelet crystals are hexagonal in shape and the hexagonal platelet crystals form steps perpendicular to the growth direction by side-by-side stacking along the (0001)η surface. The mechanism of morphological change is discussed in details. It is proposed that these steps grow laterally as a result of the embedment of zinc ion clusters.

引用

Journal of Hydrodynamics 2001年第2期13卷 32-39页

作者： Miao, G.P. Ishida, H. Saitoh, T. kurosaki, K. Sch. of Naval Arch. and Ocean Eng. Shanghai Jiaotong Univ. Shanghai 200030 China

The estimation of sloshing loading on liquid tanks is of fundamental importance due to the wide and important applications of liquid tanks in various engineering aspects. Analytical solutions for the sloshing loading on circular cylindrical liquid tanks with an interior concentric vertical thin semi-porous barrier under external excitations are presented. And the extensions of the solutions to the elastic vibrations and to the high frequency limit to count for the earthquake response are also included. A clear view on the influence of semi-porous barriers to the sloshing response of oscillating tanks is obtained by the analyses of systematic computational results. The present results may offer guidance to the corresponding design for liquid tanks of various applications and also a basis of comparison for the development of more sophisticated numerical methods for hydrodynamic and hydro-elastic analyses.

HYDRODYNAMIC LOADS ON OIL STORAGE TANKS WITH INTERIOR SEMI-POROUS BARRIERS UNDER EARTHQUAKES

引用

Journal of Hydrodynamics 2001年第1期13卷 1-7页

作者： Miao, G.P. Ishida, H. Saitoh, T. kurosaki, K. Sch. of Naval Archit. and Ocean Eng. Shanghai Jiaotong Univ. Shanghai 200030 China

The estimation of the hydrodynamic loading on cylindrical oil storage tank during earthquakes is of fundamental importance in the anti-seismic design. Interior semi-porous barriers are considered being effective to reduce the hydrodynamic response of the inner fluid and the loading on the tank wall. A reduced two-dimensional source distribution method and sub-region matching technique are developed for the prediction of three-dimensional hydrodynamic forces on oil storage tanks of arbitrary sections with interior semi-porous barriers of different configurations under earthquake excitations. Excellent agreement is observed between the present results and the corresponding analytical results for a circular cylindrical oil tank with a concentric interior semi-porous barrier, which shows the validity and effectiveness of the present method. A clear view of the influence of semi-porous barriers on the hydrodynamic response of tanks during earthquakes is obtained by the analyses of computational results, which may offer some guidance to the corresponding anti-seismic design for oil storage tanks and similar structures. The method is also extended to include the effects of the elastic vibrations of the tank.

Risk factors and prevention of biliary anastomotic complications in adult living donor liver transplantation

引用

World Journal of Gastroenterology 2007年第31期13卷 4236-4241页

作者： Satoshi Yamamoto Yoshinobu Sato Hiroshi Oya hideki Nakatsuka Takashi Kobayashi Yoshiaki Hara Takaoki Watanabe Isao kurosaki Katsuyoshi Hatakeyama Division of Digestive and General Surgery Niigata University Graduate School of Medical and Dental Sciences Niigata Japan

To evaluate risk factors of biliary anastomotic complications （BACs） and outcomes according to type of biliary reconstruction. METHODS： A total of 33 consecutive adult living donor liver transplantation （LDLT） were reviewed, 17 of which had undergone Duct-to-Duct anastomosis （D-D）. The remaining 16 patients received Roux-en-Y anastomosis （R-Y）. The perioperative factors, such as the type of graft and the number of graft bile ducts, were analyzed retrospectively. RESULTS： The overall incidence of BACs was 39.4%. The incidence of BACs was significantly higher in the patients with than without neoadjuvant chemotherapy （71.4% vs 10%, P = 0.050）. There was no significant difference in the incidence of biliary leakage in patients with D-D vs. those with R-Y. The incidence of biliary strictures following the healing of biliary leakage was significantly higher in D-D （60%） than in R-Y （0%）（P = 0.026）. However, the incidence of BACs related bacteremia was significantly higher in R-Y than in D-D （71.4% vs 0%, P = 0.008）. In D-D, use of T-tube stent remarkably reduced the incidence of 8ACs, compared with straight tube stent （0% vs 50%, P = 0.049）. CONCLUSION： Our experience showed an increase of BACs related bacteremia in the patients with R-Y. Therefore, D-D might be a preferred biliary reconstruction. However, the surgical refinement of D-D should be required because of the high incidence of biliary strictures. Use of the T-tube stent might lead to a significant reduction of BACs in D-D.

Efficient Production of δ-Guaiene, an Aroma Sesquiterpene Compound Accumulated in Agarwood, by Mevalonate Pathway-Engineered Escherichia coli Cells

引用

Advances in Bioscience and Biotechnology 2016年第11期7卷 435-445页

作者： Fumiya kurosaki Takahiro Kato Norihiko Misawa Futoshi Taura Laboratory of Medicinal Bioresources Graduate School of Medicine and Pharmaceutical Sciences for Research University of Toyama Toyama Japan Laboratory for Plant Genetic Function Science Research Institute for Bioresources and Biotechnology Ishikawa Prefectual University Nonoichi Japan

Mevalonate pathway for isoprenoid biosynthesis was constructed in Escherichia coli cells by the transformation with a gene cluster isolated from Streptomyces sp., and farnesyl diphosphate synthase and δ-guaiene synthase genes were coexpressed in this strain. This transformant was capable of liberating an appreciable amount of δ-guaiene, an aroma sesquiterpene compound accumulated in agarwood, and its concentration was elevated to more than 30 μg/ml culture by the incubation with mevalonolactone as an isoprene precursor in a nutrient-enriched Terrific broth. Coexpression of type 1 isopentenyl diphosphate isomerase plus acetoacetyl-CoA ligase genes also enhanced δ-guaiene production, and the concentration of the compound was approximately 38 - 42 μg/ml culture in the presence of mevalonolactone or lithium acetoacetate. These results clearly indicate that mevalonate pathway-engineered E. coli cells showed an appreciable δ-guaiene producing activity in the en- riched medium in the presence of appropriate isoprene precursors.
