Natural gas produces less carbon dioxide, nitrogen oxides and sulfur oxides per unit heat released than other fossil fuels such as oil and coal. In line with efforts to preserve global environment and to promote sustainable development of world economy, the demand for natural gas has steadily increased. This study was conducted to analyze the risk of GHG (greenhouse gas) release caused by accidents involving natural gas carriers. LNG, which stands for Liquefied Natural Gas, is composed mainly of CH4, so the composition of LNG was assumed to be 100% CH4. Also, the other components of natural gas are not recognized as GHG. To estimate the maximum environmental impact, “Q-Max” which is currently the largest LNG carrier was used as the reference ship. For comparison, CO2 emissions from the propulsion engine were calculated. The environmental impact due to accidents was insignificant compared with the impact of CO2 emissions from the propulsion engine.

Recently, calcined dolomite has been used as an anti-bacterial material in various applications for improving public health. Generally speaking, calcined dolomite exhibits anti-bacterial effects due to its strong alkalinity after hydration. There are authors who have reported that the calcined dolomite can generate Reactive Oxygen Species (ROS), although there are other authors who were not able to detect it. Since the anti-bacterial mechanism of the calcined dolomite is not yet very clear, it was subject to ESR (Electron Spin Resonance) spin trapping method in order to confirm the generation of the hydroxyl radical. In this work, the hydroxyl radical was detected from calcined dolomite - hydrogen peroxide (H2O2) suspension. It was found that dolomite, calcined at the relatively higher temperature between 800℃ and 1000℃, enables faster H2O2 decomposition. The results of this work indicate that calcined dolomite suspension generates hydroxyl radicals in the presence of H2O2.

最終氷期極相期における日本海低塩分化事件を定量的に説明し,陸橋成立の可能性を議論するために,浮遊性有孔虫殻酸素同位体比から日本海表層水古塩分変化を復元した.そして,復元した古塩分変動を定量的に説明するために,塩分収支モデルを用いて日本海へ流入する海水量の時代変化を計算し,それをもとに海峡水深の時代変化を推定した.その結果,LGMにおける対馬海峡の海峡水深は2~9mと見積もられたが,この値は海峡内の海底地形から直接的に推定された値10~30mよりやや浅い.海底地形に基づく海峡水深推定値と調和的な解を求めるためには,古塩分見積値を誤差範囲内で大きめにした上で,対馬海峡における流速を現在の半分まで弱める必要があり,この場合,LGMの推定海峡水深は~10mと求まった.また,最終氷期極相期における海水流入量は500km3/y以下と推定される.このようなわずかな海水流入量は,津軽海峡での潮汐流による海水交換でも説明できることから,最終氷期極相期に対馬海峡が漂砂により埋積した場合,ごく短期間陸橋が成立した可能性を否定できない.

A hybrid gas bearing with water evaporation from ultra-fine porous medium is newly proposed. The proposed bearing is considered to be applied to microturbines and have mainly three advantages suitable for the applications. The first is the stability improved by water evaporation from ultra-fine porous medium. The second is the effective lubrication by liquid water at start and stop of the journal rotation. The third is the cooling effect on the high-temperature journal due to water evaporation. A preliminary experiment is conducted, and the stable start and stop of the journal rotation are confirmed.

Trajectory of two-seam and four-seam fast ball were examined experimentally. Each special fast ball was thrown by a baseball player and a pitching machine. They were also compared experimentally. Photograph were taken by a video camera behind the catcher player. Trajectories of their balls were calculated from the photographs. Two-seam fast ball swift occasionally right and left horizontally and sometimes went down vertically. The trajectory was similar to that of other change balls such as slider and curved ball. However, the motion of the pitcher was very similar to that of four-seam fast ball. It was suggested that a batter was difficult to find out fast ball and 2-seam swift ball at a glance of pitcher.

Purpose: This retrospective case series examined wound complications after Tamai zone V replantation, and describes a potential strategy to increase the finger survival rate and improve function.Methods: Nine patients (22 fingers) underwent Tamai zone V replantation at our institution between 2011/9 and 2017/5. We performed a detailed chart review to identify features of their postoperative soft tissue progress, finger loss rate and details of additional surgeries.Results: Four patients (10 fingers) lost all replanted fingers, whereas in five patients (12 fingers) , all fingers survived. In all four failure cases, tissue necrosis developed gradually in the replantation zone covering the vascular anastomoses, and vascular thrombosis and spasm were observed approximately 1 week after the first replantation. In contrast, 3 out of 5 patients did not develop tissue necrosis. The fingers of the remaining 2 patients were salvaged by performing timely flap coverage of the necrotic tissue overlaying the vascular anastomoses.Conclusion: Early flap coverage to the Tamai zone V replantation area may be effective in preventing vascular thrombosis and spasm leading to finger loss, and it made it easier to perform additional reconstructive surgeries.

Team medical care needs to be improved at the outpatient clinic to manage highly complex cancer chemotherapy. In May 2008, Kurashiki Medical Center was the first medical institution in Japan to start a pharmaceutical outpatient clinic called a “support clinic.” At the support clinic, oncology pharmacy specialists interview patients and propose several suitable options of drug regimens to the physicians to ensure safe and effective treatment. We evaluated the functions expected of the support clinic and the appropriateness of health insurance application to the clinic's services.Physicians and nurses highly evaluated the work of the oncology pharmacy specialists at the support clinic. The function that they expected most of the support clinic was the design of supportive therapies followed by the design of treatment strategies. All 93 patients surveyed said that the support clinic was beneficial to them. Ninety-six percent of the patients considered that the support clinic services were worth paying.The support clinic has been providing oncology pharmacy specialists with great opportunities to fulfill their potential. Its services are needed by medical professionals and patients who want improved outpatient cancer treatment.

Cathode using the olivine particles was subjected to an open-circuit voltage measurement under the relaxation condition of 24 h at each SOC and DOD states. The electrochemical reaction in the LiFePO<SUB>4</SUB> cathode was composed of a large plateau around 3.45 V with sloped regions nearby for both the fully charged and discharged states. It was found that the potential profile in the sloped regions exhibited a hysteresis. Furthermore, both sloped regions became narrower when the operating temperature was raised from 30 to 60°C. Furthermore, it was found that the apparent diffusion coefficient of Li<SUP>+</SUP> ions in the sloped regions was much smaller than that in the plateau region. These facts implied that the obtained profiles were not in an equilibrium state with a quasi-OCV profile than the real one, and that the potential relaxation in the sloped regions took an extremely long time.

LiFePO<SUB>4</SUB>/C composite particles were prepared by gas-solid phase reaction. The reaction temperature had a detrimental effect on the purity of the composite particles. The suitable temperature was around 650°C, above and below which ferromagnetic impurities were found. The retention time influenced only the carbon deposition amount, but the excess amount of carbon caused the degradation of the electrochemical performance. The specimen prepared at the optimum conditions exhibited superior performances in both rate capability and cycle stability as well as less impedance growth during the cycling.

A hybrid bearing effectively stabilized by water evaporation from ultra-fine porous medium is proposed and its basic characteristics are clarified by numerical simulation and experiment. The proposed bearing aims to be applied to MGT (Micro Gas Turbine) and has mainly three advantages suitable for application to MGT. The first is the stability improved by water evaporation from ultra-fine porous medium. The second is the effective lubrication by liquid water at the start and stop of the journal rotation. The third is the cooling effect on the high-temperature journal due to water evaporation. A fundamental experiment from water lubrication to vapor lubrication via transition state has been carried out. The experiment indicated the potential of vapor lubrication and confirmed the stable start-up at water lubrication.
