<p>There is an intricate transportation network of cars and trains in the center of Tokyo. There are the layers of the network were stretched around the stations as transportation hubs that didn’t fit well in the limited space on the ground. If there are no technical problems similarly with skyscraper construction, the flow of multi- story construction is unstoppable, considering the space required and the space on the ground that is limited. Pedestrian networks are retrofitted to gaps in cities.</p><p>The span of this pedestrian deck was decided in consideration of the place where the railway runs underground and the place where it straddles the Metropolitan Expressway.</p><p>Since it is an important flow line of the pedestrian in urban areas, we verified the vibration usability of this deck especially for the largest span of it.</p><p>By measuring the bridge vibration of the actual bridge of this deck, we grasped the difference from the calculated value assumed at the time to design it and confirmed the vibration usability when the pedestrians walk on the deck.</p><p>In order not to cause discomfort to the pedestrian, the limit of the natural frequency is that the vertical vibration should not be around 2Hz (1.5 to 2.3Hz) and the horizontal vibration should not be around 1Hz, but the vibration of this deck has applied this restriction. From the displacement and velocity values obtained from the external force, it was judged that no countermeasures were necessary.</p><p>It can be evaluated that the actual bridge also satisfies the vibration limit, there is no problem in vibration usability.</p>
The flow characteristics in the bubble column, in the case of highly viscous liquid, were experimentally examined. Carboxymethyl cellulose (CMC) aqueous solution was used as the liquid phase, and the liquid height, column diameter, gas velocity and CMC concentration were changed. The flow pattern was observed, and the gas holdup and volumetric mass transfer coefficient were measured.When a large bubble, or slug, flowed out of the liquid surface, the liquid surface was violently disturbed and small bubbles were entrained into the liquid. The entrained small bubbles had a significant influence on the flow characteristics. The gas holdup and volumetric mass transfer coefficient decreased with increasing liquid height and were unchanged beyond a certain liquid height. The critical aspect ratio of the column was about 8, independently of the column diameter, gas velocity and liquid viscosity. Experimental equations on the volumetric coefficient were obtained.
NATM によるトンネル施工では,切羽前方地山の安定を確保することがトンネルを安全かつ安定に施工するために必要である.特に地山強度比が小さな押し出し性地山においては,切羽前方地山を補強するための対策工として,長尺鏡ボルト工が広く採用されている. 本論文では軸対称 FEM を用いて,長尺鏡ボルト工による効果を定量的に評価するための簡易モデルを提案し,内空変位と地表面沈下の計算結果を計測結果と比較することでその実用性を明らかにする.
The clinical efficacy and safety of Netilmicin (NTL) and Sisomicin (SISO) were compared in thisrandamized, double-blind study of 226 patients with respiratory tract infections.Patients were assigned to treatment with either 100mg of NTL or 75mg of SISO by intramuscularinjection twice a day for 7 to 14 days.The results obtained were as follows:1) Patients subject to analysis: One hundred and eighty-nine patients were adopted for evaluationof clinical efficacy by committee members. Of these patients, 96 were treated with NTL and 93 with SISO. The number of patients treated with NTL and SISO was, respectively, 63 and 57 inpneumonia, 0 and 2 in pulmonary abscess, and 33 and 34 in chronic respiratory tract infections.Two hundreds and seventeen patients were adopted for analysis of clinical efficacy by controllersafter judgement of clinical efficacy by doctors in charge. Of these patients, 107 were treated with NTLand 110 with SISO. The number of patients treated with NTL and SISO was 80 and 70 in pneumonia, 5 and 12 in pulmonary abscess, and 22 and 28 in chronic respiratory tract infections, respectively.2) Clinical efficacy: The clinical efficacy rate (excellent and good responses) in all cases judgedby committee members was 65% in NTL group and 71% in SISO group, respectively. For pneumoniathe efficacy rate was 79% in NTL group and 75% in SISO group, with no significant difference betweenthe two. For chronic respiratory tract infections the efficacy rate was 36% in NTL group and 65% in SISO group, and difference was significant (p<0.05).The clinical efficacy rate in all cases judged by doctors in charge was 67% in NTL group and 67%in SISO group, respectively. For pneumonia the efficacy rate was 74% in NTL group and 73% in SISOgroup. For pulmonaly abscess the efficacy rate was 80% in NTL group and 42% in SISO group. Forchronic respiratory tract infections the efficacy rate was 41% in NTL group and 64% in SISO group. Overall, or judged by doctors in charge there was no statistical difference between NTL and SISO.3) Degree of symptomatic improvement: There was no statistically significant difference in thedegree of improvement.4) Bacteriological efficacy: There was no significant difference in the bacteriological efficacy.5) Adverse reactions: The adverse reactions of NTL group and SISO group were similar in typeand frequency, except that the eosinophilia was observed significantly more frequently in patientstreated with NTL than in those with SISO (p<0.1), judged by committee members.6) Utility: There was no significant difference in the utility judged by doctors in charge.
We report what we believe to be the first clinical isolation of Legionella rubrilucens from a pneumonia patient co-infected with Legionella pneumophila. L. rubrilucens strains were found in both a patient's sputum and the water of a hot spring in which the patient bathed, and DNA analysis by PFGE showed that they were indistinguishable.
