BACKGROUND Endoscopic resection(ER)with bipolar snare,in which the electric current only passes through the tissue between the device’s two electrodes,is a prominent method used to prevent perforation due to electricity *** using bipolar snare with or without submucosal injection enabled safe resection of colorectal lesions measuring 10-15 mm in an ex vivo porcine *** with bipolar snare is expected to have good treatment outcomes in 10-15 mm colorectal lesions,with high safety even without submucosal ***,no clinical reports have compared treatment outcomes with and without submucosal *** To compare the treatment outcomes of bipolar polypectomy with hot snare polypectomy(HSP)to those with endoscopic mucosal resection(EMR).METHODS In this single-centre retrospective study,we enrolled 10-15 mm nonpedunculated colorectal lesions(565 Lesions in 463 patients)diagnosed as type 2A based on the Japan Narrow-band Imaging Expert Team classification,resected by either HSP or EMR between January 2018 and June 2021 at the National Cancer Center Hospital *** were divided into HSP and EMR groups,and propensity score matching was *** the matched cohort,en bloc and R0 resection rates and adverse events were compared between the two *** Of the 565 lesions in 463 patients,117 lesions each in the HSP and EMR groups were selected after propensity score *** the original cohort,there was a significant difference in antithrombotic drug use(P<0.05),lesion size(P<0.01),location(P<0.01),and macroscopic type(P<0.05)between the HSP and EMR *** the matched cohort,the en bloc resection rates were comparable between both groups[93.2%(109/117)vs 92.3%(108/117),P=0.81],and there was no significant difference in the R0 resection rate[77.8%(91/117)vs 80.3%(94/117),P=0.64].The incidence of delayed bleeding was similar in both groups[1.7%(2/117)].Perforation occurred in the EMR group[0.9%(1/117)]but not in the HSP ***

＜正＞Recycling should be promoted to protect the global environment;however, it is difficult to determine its quantitative impact. A life cycle assessment （LCA） becomes currently the most popular method to estimate the impact. The metal-plated resin is the popular material for the parts of the car and furniture. However, it is a difficult material for recycling as the composite material of resin and metal. Recently, the recycling method, which was used by grinding and separation, was developed by Idemitsu Technofine Co., Ltd.. The environmental impact such as the CO2 emission and the yield of waste was estimated for the recycling process by LCA. As a result, it became clear that the recycling process was efficient for the environment.

Journal of Thermal Science 2011年第2期20卷 155-160页

作者： Shin-ichi MORITA Yasutaka HAYAMIZU Hideo inaba Department of Mechanical Engineering Yonago National College of Technology Tsuyama National College of Technology

The purpose of this study is the development of latent heat transport system by using the mixture of the minute latent heat storage materials and the saccharine solution as medium. The experimental studies are carried out by the evaluation of viscosity and pressure loss in a pipe. Polyethylene (P.E.) is selected as the dispersed minute material that has closeness density (920kg/m3) of ice (917kg/m3). D-sorbitol and D-xylose solutions are picked as continuum phase of the test mixture. The concentration of D-sorbitol solution is set 48mass% from measured results of saturation solubility and the melting point. 40mass% solution of D-xylose is selected as the other test continuum phase. The non-ion surfactant, EA157 Dai-ichiseiyaku CO. Ltd, is used in order to prevent of dispersed P.E. powder cohere. The pressure loss of test mixture is measured by the straight circular pipe that has smooth inner surface. The measuring length for pressure loss is 1000 mm, and the inner diameter of pipe is 15mm. The accuracy of experiment apparatus for measuring pressure loss is within ±5%. The pressure loss data is estimated by the relationship between the heat transport ratio and the required pump power. It is clarified that the optimum range of mixing ratio exists over 10mass% of latent heat storage material.

Preparation of Lanthanum Nickel Oxide-Coated Ni Sheet Anodes and Their Application to Electrolytic Production of (CF_3)_3N in (CH_3)_4NF·4.0HF Melt

引用

Journal of Rare Earths 2006年第1期24卷 1-8页

作者： Yoshio Shodai Minoru inaba Kazuki Onoda Akimasa Tasaka Department of Molecular Science and Technology Faculty of Engineering Doshisha University Kyotanabe Kyoto 610-0321 Japan

A new process for electrolytic production of a perfluorinated compound, （CF3）3N, using lanthanum nickel oxide-coated Ni sheet anode in the （CH3）4NF· 4.0HF melt at room temperature, was developed. Thin films of the lanthanum nickel oxides were prepared on Ni sheets by sol-gel coating method using polyvinlylpyrrolidone（PVP）. The main components of the thin films were La2O3, LaNiO3, and La2NiO4 at 500, 750 and 1000℃, respectively. The anode performance in the （CH3）4NF·4.0HF melt depends greatly on the main component of the thin film, and the LaNiO3-coated Ni sheet anode gives the best anode performance. The potential of LaNiO3-coated Ni sheet anode remains constant at 5.9 V during electrolysis at 20 mA·cm^-2 in the （CH3）4NF·4.0HF melt for 100 h. This is because LaNiO3 and NiF3 and/or Ni2F5, the latter of which was formed during electrolysis, in the film give a high electronic conductivity to the surface film during electrolysis. The maximum mole fraction of （CF3）3N （21.4%） was obtained at 20 mA·cm^-2 in （CH3）4NF·4.0HF melt using the LaNiO3-coated Ni sheet.

The purpose of this study is to understand the factor that influence the heating efficiency of the outward and inward multi-hole gas burner. The flame-hole angle and the distance from flame hole to heating object are chosen as the experimental parameters. The measurement of the flame temperature distribution is carried out on each experimental condition. The observation of combustion flame, by the Schlieren method, is done from the purpose to understand the combustion phenomenon on the heating efficiency. LPG (Liquefied petroleum gas) is used for the test fuel gas. The compositions of LPG are propane 97.5vol%, butane 0.2vol% and methane + ethylene 2.3vol%. The optimum ranges of the flame-hole angle and the distance from flame hole to heating object are clarified. The experimental correlation equations for the outward and inward multi-flame-hole gas burner are proposed.
