In this paper, dynamic stability analysis methods of a beam subjected to a confined annular axial flow are dealt with. Such structures are submarine resources production pipeline, reactor core structures of nuclear power plants, high-speed trains passing thorough a tunnel, a piping system in the field of ocean mining, and so on. The relation between the annular axial flow velocity and the unstable dynamics of structures are clarified. We have compared two analysis methods which can evaluate the dynamic instability of such structures. In first analysis method, the fluid is treated as viscous fluid, and is governed by the Navier-Stokes equation, and the beam structure is treated as the Euler-Bernoulli beam. This is called as the viscous fluid solution namely NS solution hereafter. In second analysis method reported by (Rinaldi and Paidoussis, 2012), the fluid is treated as ideal fluid. Then the viscosity effect is added to the equation of motion. This is called as the ideal fluid solution namely R&P solution hereafter. The complex eigenvalue analysis of the fluid structure coupled equation of motion is performed in order to clear up the dynamic instability. Performing the parametric studies, the comparison between both solutions is investigated. When the fluid viscosity becomes large, the difference in the critical velocity between the viscous fluid solution namely NS solution and the ideal fluid solution namely R&P solution is found to be generated. The destabilization effect appears due to the fluid viscosity force terms of the added stiffness of the fluid-structure coupled equation only in the viscous fluid solution.

Reported: This autopsy case of myasthenia gravis in a 41 year old female revealed thymus hyperplasia with germinal centers remaining in the fatty tissues. The infiltration of lymphocytes (lymphorrhage) was remarkable only in the tissues near the thymus, namely the intercostal muscles, myocardium, and thyroid; in the other affected skeletal muscles, it was only slight. The Lymphorrhage in the myocardium was so remarkable that was histologically diagnosed as subacute myocarditis.Discussed: In agreement with recent studies, these findings seem to suggest the view that myasthenia gravis is an autoimmune disease.

Vitamin K2 (K2) syrup has begun to be administered to newborn for prophylaxis of intracranial hemorrhage due to vitamin K deficiency. The stability of K2 syrup (2mg/ml) and its diluted solution (0.2mg/ml) in a plastic bottle with or without an orange bag to exclude light was examined by micro high pressure liquid chromatography.When light was excluded by the orange bag, regardless of a color of bottle, the concentration of K2 and storage temperature, the residual rate of K2 in an ophthalmic bottle (10ml) was more than 90% after 1 month under a fluorescent light (500 lux) shed for 10-12 hours per day. But when light was not excluded by the orange bag, K2 decomposed to less than 40% and was somewhat more stable in a brown-colored bottle than in a colorless bottle, and in syrup than in its diluted solution. K2 in a dispensing bottle (30ml) without a light-resistant cover decomposed to 76-85% in only 9 hours under fluorescent light.Therefore, K2 syrup and its diluted solution should be administered in light-excluding containers. Photodegradation of K2 in the plastic bottle was inhibited when stored in an orange bag.

A long flexible shaft such as a lance tube in a soot blower or a drill string in a rotary drilling system exhibits friction-induced vibration resulting in a whirling motion. This paper investigates the whirling motion of a long flexible shaft induced by frictional force and examines the effect of an intermediate support position on the whirling motion. The experimental apparatus investigated has a vertical shaft which rotates at a constant speed by means of an electric motor mounted at the top of the shaft. At the bottom end of the shaft is located a rubber ring so that frictional force acts on the tip of the shaft when the shaft is deflected. Comparing experimental and calculated results we clarify the vibration characteristics, such as whirling frequencies and amplitudes, at various rotational speeds and show the effective position of an intermediate support to suppress shaft vibration.

GLP-1およびGIPは共に血糖依存的にインスリンを分泌させる他、様々な臓器で多様な作用を持ち糖代謝に深く関与している消化管ホルモンである。本研究では栄養組成の違いがネコのインクレチン分泌におよぼす影響について検討することを目的とした。日本獣医生命科学大学で飼育管理されている健常猫5頭に、コントロール食、高炭水化物食、高脂肪食、高繊維食の4種を給与し、血糖値、インスリン濃度およびインクレチン濃度を測定した。GLP-1濃度変動は4種の食事で差はなかった。この結果は、ヒトでは炭水化物と脂質がGLP-1分泌に大きく影響をおよぼしているという報告とは異なるものであった。これはネコの食性や消化管構造の違いによる影響と考えられた。一方、GIP濃度変動はコントロール食と比較し高脂肪食で有意に高値を示した。また、食事中の脂肪含量が多いほどGIP濃度も高値を示した。本研究により、ネコにおいて栄養組成の違いがGIP分泌におよぼす影響について明らかとなったが、GLP-1分泌については今後さらなる検討が必要である。

糖尿病猫はしばしば感染症に罹患しやすいといわれており、またストレス性の高血糖を生じやすく、血糖値を降下させるのも不得手な動物種である。このような特性をもつ猫の糖尿病管理においては、血糖コントロールを悪化させる原因が数々存在するため、糖尿病猫の入院管理は時に困難をともなう。そこで本学に来院した、慢性感染症を併発した猫、入院によるストレスで血糖コントロールが困難となった猫、食事変更が必要となった猫について、その問題と対策について検討した。症例によってストレスを感じる事象は様々あり、その対処も大きく異なるものであった。同時に、院内で起こる特有の問題からの学びもあり、退院後の自宅でのケアに生かすことができた。病院という制限ある集団管理においても、可能な限りその個別性を大切に、それぞれに合った生活環境を整える工夫ができるかが動物看護師の重要な仕事であると考える。

The presence of three kinds of hydrates of AM-715 (1-ethyl-6-fluoro-1, 4-dihydro-4-oxo-7-(1-piperazinyl)-3-quinolinecarboxylic acid) was confirmed by elemental analysis, Karl-Fischer method, thermogravimetric analysis, differential scanning calorimetry, infrared spectroscopy, and X-ray diffractometry. Anhydrous AM-715 was not hygroscopic under less than 36% of relative humidity, but easily transformed to 5/2-hydrate over 62-78% of relative humidity and 5-hydrate above 94% of relative humidity, at 40°C. Anhydrous AM-715 was transformed to 5/2-hydrate with the first-order kinetics and 5/2-hydrate was dehydrated according to the first-order kinetics with an activation energy of dehydration of 22 kcal/mol. The 5/2-hydrate was converted to 5-hydrate much slowly than anhydrous AM-715. Dissolution rates were determined in water by using tape procedure, showing a slight difference between anhydrous AM-715 and its hydrates. In order to determine the effect of hydration on bioavailability, the serum levels in dogs were measured after oral administration. There were no significant differences among bioavailability of anhydrous AM-715, its 5/2-hydrate and 5-hydrate.

A range sensor is known as one of sensors which are often installed in mobile robots. The range sensor can detect the distance to objects in the environment using laser beam. However, the measurement area of the range sensor is limited because the scanning plane of the sensor is single and parallel to the mounting surface. In this research, we developed a new range sensor capable of scanning in two directions. Using the periodic refraction of laser beam generated by the rotation of two acrylic prisms installed around the range sensor, two-directional scanning is realized. If this range sensor is placed at the front of the mobile robot horizontally, the robot becomes possible to scan both distant area and road surface. In addition, we devised a simple method for the classification and integration of two-directional measurement data based on a model fitting method. In this paper we describe the concept of the range sensor device and explain the method for the classification and integration of two-directional measurement data. Furthermore, we verified the range sensor's effectiveness through object detection experiments.

For the development of industrial heat pump systems supplying high-temperature heat source over 130 °C, experiments were carried out on cooling heat transfer of supercritical pressure HFO1234ze(E) flowing in a plate-type heat exchanger (PHE). HFO1234ze(E) with low Global Warming Potential (GWP) is expected as an alternative to refrigerant HFC134a. In the experiment, heat transfer coefficient data were obtained at different pressures including a near-critical pressure condition. To obtain the heat transfer coefficient, an integral method was used for evaluating the mean temperature difference between the refrigerant and cooling water in the PHE. Based on the measurements, characteristics of cooling heat transfer of supercritical pressure HFO1234ze(E) in the PHE were clarified. Generally, heat transfer coefficient showed considerably large values compared with tube flow, attributed to strong turbulence or agitation promoted by corrugated geometry of the PHE plate, and reached a maximum in the vicinity of the pseudocritical point. As the pressure approached the critical pressure, the peak of heat transfer coefficient became higher at lower bulk enthalpy, reflecting the pressure dependence of isobaric specific heat of the refrigerant. These results mean, even in the pseudocritical region where strong temperature dependency of physical properties appears, properties change in the flow cross section was small compared to the tube flow, although not negligible. The correlation developed in the previous study overestimated the measured heat transfer coefficient in the pseudocritical region for the pressure of the reduced pressure 1.01 very close to the critical pressure and also in the enthalpy region near to and lower than the pseudocritical point for the pressures of the reduced pressure about 1.1 or higher. For the better prediction, the necessity to consider the small but non-negligible properties change in the flow channel cross section was recognized.

Since mid 1990s Japan has been promoting a big scale reform of the basic governmental institutions. Transfer of functions to local goverments, deregulation, reshuffle of government ministries and financial structure reform are advancing and the civil service reform has just started. These reforms are to reform a govermental organization that has grown excessively large and rigid, and to realize a streamlined, efficient and transparent goverment that permits effective execution of important state functions. In this article, political or law-making process of two reforms are analyzed. One is the reinforcement of cabinet functions. In order for the Cabinet to conduct substantial policy discussions, and to function as the principal instrument for a top-down approach to the formation and execution of policy, it is necessary to reinforce the Cabinet functions and to strengthen the "leadershp of the Prime Minister" The second is the establishment of independent administrative corporations. Government organizations are criticized because of inefficiency, rigidity and a big financial deficit. So independent administrative corporations are established as a strong tool for increasing efficiency and improving the quality of administrative services.
