Gene transfection to cancer cells using nanobubbles and ultrasound (NBs-US) is a non-invasive gene therapy. Herpes simplex virus thymidine kinase (HSVtk) gene is a representative suicide gene, and has been demonstrated to have potential of cytotoxic sensitivity by ganciclovir (GCV). In this report, we evaluated the effectiveness of HSVtk/GCV cytotoxic gene therapy on cancer cells using NBs-US. For in vitro studies, HSVtk was trasnfected into five cell lines (A549, EMT6, colon26, HT29 and 293T) with NBs-US (0.6MPa). The effects of HSVtk/GCV gene therapy were evaluated using an MTT assay. For in vivo studies, HT29 cells expressing luciferase gene were trasnsplanted into mice. HSVtk was transfected into tumor with NBs-US and GCV was administrated intraperitoneally. Luciferase activity regarded as tumor size was measured by a bioluminescence imaging system. Both in vitro and in vivo studies, cytotoxixity was obtained only in the treated cells with HSVtk/GCV. These results demonstrated the potential to treat cancer cells by using the NBs-US method combined with suicide gene therapy.

We found that the stiffness of bone tissues cultured under cyclic compression increased significantly. But it was not clear whether this change was an active adaptation of the cells in bone or it was just a passive change of the tissue. To clarify this, bone tissues including those treated with liquid nitrogen to kill cells were cultured under cyclic compression. Cell viability was measured in specimens cultured in various conditions. The stiffness of bone tissues without living cells did not increase. Thus, we confirmed that the stiffening of the specimens exposed to cyclic compression culture is an active change in the bone tissue.

In this report, we describe the surface error of pseudo-parabolic surface, to construct an inflatable parabolic reflector. The gore sheet is generated by cutting the three-dimensional parabolic surface. A scheme of generating the gore sheet is described, and the rms surface error between the parabolic surface and the three-dimensional shape composed of the gore sheets is proposed and formulated. The rms surface error between the parabolic surface and the shape produced by pressurizing the circular membrane is also formulated. Finally, the possibility that the parabolic reflector composed of the gore sheets has high surface accuracy is shown.

This paper deals with a method to determine dynamic characteristics of space structures by component modal tests. This method uses additional mass and stiffness to consider the effect of untested components. Modal test results depend on a location with additional mass and stiffness. We select optimal location using information about variations of two masses. These masses are found by reducing mass matrices of a tested component and a structure to an arbitrary degree of freedom. It is effective to select the location with large modal amplitude of structure modes for the accuracy of measured frequency and mode in component modal tests. A numerical example is given to show the effectiveness of the method.

The purpose of this study is to develop a vibration characteristic of space antenna structure composed of inflatable structure and CFRP, and we do a micro gravity test using a parabolic flight by a jet plane. Because of this structure is very light, so we can't fix sensors on it. Therefore we try to measure it without contact by using image processing and we find that the first natural frequency of this structure is about 2.77Hz. Then, we carry out dynamics analysis with a single degree of freedom (SDOF) model and we obtain that the frequency of SDOF model is 3.04Hz and it is very close to the result of micro gravity test.

Wrinkling phenomena have been investigated in many researchers to clarify the effect of the performance deterioration in order to apply the membrane structure to the space structure. However, studies are concentrated on the effect of variations of initial imperfection or membrane thickness to the structural performance. This study describes a development of a stochastic process model for membrane structures with uncertainty. In numerical analysis, the difference of autocorrelation function is investigated between a nominal constant-thickness membrane and a thickness-variated membrane.

An experimental identification method of impact force acting on composite structures is presented. The experimental relation between force histories and strain responses is first determined through impact tests with an impulse hammer. By employing this relation, the location and history of impact force is identified using measured strains. The validity of the present identification method has been verified through the impact test of cantilevered CFRP stiffened panel. The method can also be applied to the impact force identification in CFRP laminated plates involving impact damages under a drop-weight impact test.

Many studies have been reported about the catalytic recombination of oxygen and nitrogen on silicon dioxide surface, which is quite important for the reentry of a space vehicle. But, the reaction mechanism is not fully understood. Hence, in this study, we are constructing a catalytic reaction model using the ab initio calculations and the Monte Carlo calculations in order to reveal the reaction mechanism. Here, the adsorption and desorption of O and N atoms were investigated on the α-quartz (0001) surface ended with Si atoms using density functional theory and standard transition state theory. The adsorption energy of 7.55eV for O and 5.29eV for N were obtained, and large impact of the surface coverage ratio on the adsorption process was confirmed.

In this study, [0/0/90/90]_s and [0/90/0/90]_s laminates were used as stacking sequences of the CFRP cross-ply laminates. At first, these CFRP cross-ply laminates were subjected to biaxial loading with fixedd load ratio (1:1 or 1:1.5), and matrix crack developments were observed using ultrasonic C-scan. After that, leakage at each initial damage level was measured under low biaxial loading by helium leak detector. Through the test results, the influence of stacking sequences, load ratio and damage density with increase of initial damage level on leakage properties was studied.

This paper describes the role of Polyhedral Oligomeric Silsesquioxane (POSS) nanomaterials in improving the oxidation resistance of carbon-carbon composites by matrix modification. It is expected that POSS containing composites will have improved oxidation resistance because, in a severely oxidizing environment, silicon and oxygen of the POSS oxidize to form silicon dioxide. Since silicon ceramics exhibit the most attractive thermal expansion compatibility with carbon composites, the protective silica layer will prevent the oxidation of the composite without adversely affecting its performance. Two types of POSS, octaisobutyl POSS (OIBP) and trisilanol phenyl POSS (TSPP) are incorporated in phenolic resin and the dynamic mechanical and thermal properties of the resultant composites are studied. POSS incorporated phenolic resin is then used for the preparation of carbon-carbon composites. It is found that in presence of POSS, the thermal stability of the composite is improved both in inert and oxidative environment.

This paper discusses on control law of the micro-gravity experimental vehicle with a balloon. To attain the micro-gravity environment, it is necessary that the experiment sphere in the experiment module does not collide with inner shell of the vehicle. This is achieved by designing the control law with 16 gas-jet thrusters. The velocity during free fall is accelerated to a supersonic region by the end of experiment. The design of control law corresponding to the remarkable increase of dynamic pressure is required. The performances of actual thrusters have high non-linearity. This paper proposes a new control law of thruster to control the vehicle with high accuracy.

The capturing strategy to capture the debris in the earth orbit is one of major concerns of recent space development. Multi-joint space structure is used to capture these debris, but the control method of these structures are difficult due to its complicated system and the motion of the debris. In this paper, the motion of the space structure is control using optimal periodic controller with delayed feedback control. The results show that due to the characteristics of the system like multi-joint space structure, the delayed feedback control does not work well as it is expected.

This study deals with orbital transfer of a rigid satellite system into a specified orbit by using its inner force generated in the system. First, the governing equations of the system are shown. Subsequently, it is also shown the system can be represented as symmetrically affine system which has two inputs for three variables to be controlled. Then, this paper proposes a two-step approach, combining a solution for a 'chained' system and numerical modification based on 'motion planning'. Finally, computational simulations verify that orbital transfer to a specified orbit is accomplished successfully by applying the proposed approach.

This paper discusses on the accuracy of guidance and control law for an unmanned lunar landing module. The guidance law is required to avoid obstacles on a lunar surface automatically during vertical descending. The maximum distance of horizontal avoidance depends on the accuracy of control, because wider area is necessary for a poorer controller. The other hand, the accuracy of controller depends on the distance of avoidance. The main purpose of this paper is to show the requirement of avoidance maneuver for a lunar landing module subject to actual conditions. The results show that the error of controller is less than 1.5[m] at landing and the required distance of horizontal avoidance is as long as 50[m]. Numerical simulations also show that the thrusters with common performance satisfy the requirements.

Recently, the development of nano-satellites for space engineering education and the demonstration experiment on orbit is very active. The cost of the development of the nano-satellites is very low, and the period of the development is very short. However, they become debris when they reach the end of their lives, which is a threat to future spacecrafts. In this paper, a de-orbit device using a membrane structure is proposed for the nano-satellite. At the end of the life, the satellite deploys the device to increase the aerodynamic drag, which hastens the de-orbit.

We have measured debris cloud generated by oblique impact. And in order to evaluate effect of oblique impact of aluminum spheres against a thin laminated target, hypervelocity impact test have been conducted. Impact velocity was approximately 2km/s. Impact angle was 0[deg] and 30[deg]. The experiments were performed to take images of the generated debris clouds behind target using three flash x-rays and to capture them softly using a stack of polystyrene sheets. And then, the images were analyzed to measure the velocity of each fragment. And the mass of recovered fragments were measured. As a result, it is found that at the impact obliquity of 30[deg], heavier and faster fragments were generated with a spray angle ranging from 20[deg] to 30[deg].

Two stage light gas guns, which were small, middle and large size, were installed at Hypervelocity Impact Test Facility Laboratory of Spacecraft Environment Interaction Engineering Kyushu Institute of Technology to conduct space debris impact test. The large one achieved a maximum muzzle velocity of 6.2km/s and the middle one achieved the maximum muzzle velocity of 7.9km/s, whereas the operational muzzle velocity of the small one remained 4km/s. However, operation at high muzzle velocity area of the small two-stage light gas gun was required in order to simulate space debris impact in low earth orbit and to realize a counter-fire with over 10km/s of impact velocity. Therefore, we carried out the muzzle velocity improvement of small two-stage light gas gun with a goal of over 7km/s.

The impacts above 10km/s between space debris and space structure often occur in the low earth orbit. Two-stage light gas gun which is commonly used in on-ground hypervelocity impact test cannot obtain that velocity. Then, we propose counter-fire by opposite two launchers. In this time, we conducted reverse impact tests which in a target was launched to a stationary projectile installed in the trajectory. At the same time, the target was recovered by guide rail system and an X-ray photograph of impact was taken. In the end, the target shape was changed to tubular structure mounted a bumper in order to observe debris cloud generated after the impact.

Authors investigated the ruins of Zippori of the third century AD. Zippori is located in north-northwest 6.7km of Nazareth and is the ancient Roman Empire city where the Byzantine culture was prosperous. Wheel ruts were discovered at the stone pavement of a main street "Cardo" of the north and south. As a result of having measured a gauge of wheel ruts, value of 1,400mm at two places and 1,200mm at one place was obtained. The measured value is nearly dose to the international standard gauge of current railway of 1435mm. A gauge of a chariot of the Roman Empire Era reaffirmed that it was the origin of a railway gauge of the present day.

The technology which recycles used clothing into the cotton began in Meiji era with Japan. Along Gunkai River forming the border between Okazaki City and Toyota City, Aichi Prefecture, There were a lot of braking factories and Garabo spinning factories the power of which was a waterwheel. Among these, neighboring Nakanetoyozo factory and Mitoyama spinning and weaving factory shared a waterway, the former equipped with a Japanese-style waterwheel 6.2 meters in diameter and the latter equipped with two water turbines. We report on the power transmission system and the water utilization system of these braking factories.

The Y-shaped lumbers of the chestnut trees were excavated at the Sakuramachi-Site in Oyabe City, Toyama, Japan in 1997. It is thought that the people of the Jomon period about 4000 years ago used the Y-shaped lumbers to transport heavy items such as giant trees. The positioning of Y-shaped lumbers in the history of sledges in Japan is discussed in this paper. The Y-shaped lumbers of the Sakuramachi-Site were compared with sledges excavated in Kitoragawa-Site of the Yayoi period in Higashiosaka City, Osaka Prefecture, Japan. It was confirmed that the Y-shaped lumbers of the Sakuramachi-Site is the oldest Shura in the world for the transportation of giant trees under the assumption that the Y-shaped lumbers at the Sakuramachi-Site are Shura.

An intoroductory education was reopened on the second grade in Department of Mechanical Engineering of Kobe City College of Technology. Four fields of mechanical engineering, that is, history of technology, material, energy, and control and information, were presented by the omnibus style. Additionally, the engineer, who were graduate of our college, was invited to lecture to the class. His lecture was valued high, because not only the students were familiar with him as their senior, but also his lecture was very practically as a engineer. After the lecture, they changed to take memos and were interested in mechanical engineering again. We succeeded in reopening the intoroductory education.

This paper described a manufacturing education for improvement of manufacturing capacity of the student. The 5-inch gauge railway model is produced, and the produced locomotive is changed to a hybrid system. In this manufacturing education, the manufacturing capacity of the student who participated in production is improved, because the upperclassman coaches the underclassman for manufacturing parts of the railway model. As a result, both got improvements of the manufacturing capacity. And result of the hybrid system, the energy efficiency of about 20% is improved.

The JABEE is changing the engineering education in Japanese universities, but has not achieved considerable results as yet because the attitude and system of the latter are not fully compatible with the formation of professional engineers. As reported in the previous paper, in the United Kingdom the engineering education at universities is wholly in the process of professional engineers in which the Chartered Engineer is ranked as the highest ones, and provides us many hints about the engineering education practice. Here, some useful items are picked up and discussed their possibility.

A verification of the introductory subject "A guide to Engineering", which was designed for the freshmen of the mechanical engineering department in Kyushu University and was introduced in 2000 school year, is performed by the experiences of the authors and the results of questionnaires to both the students and the professors. This subject has the high educational effect, and on the other hand, requires too much work of the professors. The difficulty of choice of the theme for the freshmen makes some of the professor choose the graduation-research-like-themes, which give the professor much more work which cannot be completed by his own efforts. The solutions of some problems including the above problem are proposed in order to make this subject continue to grow.
