[BABHY]
Development of the method of Baby Borehole Hydraulic Fracturing, BABHYFeaturesFor the effective measurement of the reopening pressure in hydraulic fracturing, it is necessary to use the testing equipment with sufficiently small compliance. This limitation makes it difficult to apply the hydraulic fracturing for the measurement of the maximum stress, because the compliance of conventional equipments is generally so large. Taking account of this situation, we proposed a new concept which allows us to do the in-situ tests of hydraulic fracturing for stress measurement at so deep depths as more than 1 km. We call the concept the Baby Borehole Hydrofracturing, BABHY for short. In order to put the new concept into practice, we developed the BABHY sonde and finally we succeeded to carry out hydraulic fracturing test by using the tools in a vertical borehole of 811 m depth. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry.

[Bacteria]
Development of next-generation sterilization method by a plasma flow at atmospheric pressureFeaturesPlasma sterilization has been developed as an alternative sterilization method due to its chemical activity, operation at low temperature and atmospheric pressure, low power consumption, low cost and safety. We have studied a mechanism of chemical species generation and transport in a plasma flow and, the sterilization efficacy and mechanism for several plasma sources at atmospheric pressure, such as a microwave plasma flow, a dielectric barrier discharge in a tube and a water vapor plasma flow. We already clarified that the damages of outer membrane and destructions of the cytoplasmic membrane of Escherichia coli by exposure to the microwave plasma flow. Fig. 1 shows the effect of plasma exposure on the E. coli. When the E. coli was exposed to the plasma, the height of the E. coli decreased and the potassium leakage of cytoplasmic material increased. For sterilization in a tube, we also clarified that an induced flow in the narrow tube by DBD transports chemical species and sterilize the whole inside surface of a tube as shown in Fig. 2. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry. |
[Bacteria-induced deterioration]
Oral Biofilm Functional Analysis: from “What Are They?" to “What Are They Doing?"FeaturesA large number of microorganisms inhabit the oral cavity, such as the teeth, gingiva and tongue, in the form of oral biofilm. The oral cavity forms an ecosystem where the host (humans) and parasites (microorganisms) coexist. Disruption of the balance of this oral ecosystem leads to dental caries, periodontal diseases and oral malodor, and even deterioration of dental materials.

Methods to Restore Strelity of Gramineous Plants under High- and Low-Temperature Stress ConditionsFeaturesPlant reproductive development is more sensitive than vegetative growth to many environmental stresses. High-temperature injury is becoming an increasingly serious problem due to recent global warming. In wheat, barley, and other crops, the early phase of anther development is most susceptible to high temperature. Oppositely, grain yields in rice plants are often reduced by exposure to low temperature. Unexpected climate change, such as abnormally hot or cool summer temperatures, have occurred repeatedly during recent years. This method indicates that an appropriate use of specific phytohormones, such as auxin and GA, may promote stress tolerance and adaptation to abiotic stresses. Targeted Application(s)/IndustryThese potentially novel functions of the classical phytohormones will be important sustainable agriculture in the face of global climate change. |
[barometric sensor]
Assessment of Physical Activities Using Wearable SensorsFeaturesMaintaining appropriate amount of physical activity is essential for health and disease prevention. Gait is the most common type of physical activity in everyday life. Monitoring the amount of physical activity in everyday lives may benefit mainly those who are at threat of metabolic syndrome and overweight. Towards better estimation of the amount of physical activity utilizing wearable sensors, we focused on taking running and walking economy into account. The relationship between step length and oxygen uptake was first determined. Step length estimation with moderate accuracy was accomplished using acceleration signals during walking. Step length was then taken into energy expenditure calculation as one of the variables. Targeted Application(s)/IndustryTogether with the basic version of the current locomotion monitoring system capable of counting staircase climbing up & down, we managed to upgrade our locomotion monitoring system into 3 dimensional. |
[baroreflex sensitivity]
Quantitative Evaluation of the Baroreflex Sensitivity of the Heart and ArteryFeaturesMetabolic syndrome is an important view point, when we consider the preventive medicine. Hypertension is one of the most important points to prevent the cardiovascular events. However, there is no method to measure the baroreflex sensitivity of the artery in the patients with hypertension. Tohoku University had invented the new method to evaluate the baroreflex sensitivity of the heart and artery (JP Patent No.4789203). Targeted Application(s)/IndustryBy the use of this machine, the baroreflex sensitivity of an artery in the patients can easily be measured noninvasively. It enables to predict the occurrence of hypertension and evaluate the therapy of hypertension easily, while allowing prevention of the cardiovascular events. |

[bio-magnetic sensor]
Development of High Sensitive Magnetic Sensor Operating at Room Temperature with Tunnel Magnetoresistance DevicesFeaturesRecently, many tunnel magnetoresistance devices with high magnetoresistance effect are reported. These are expected to be applied to high sensitive magnetic sensors. There are many magnetic sensors with variety of the mechanism, in order to meet the demand of the very wide range of sensing magnetic field. However, there is no magnetic sensor which has high sensitivity, easy to use, operation at room temperature and low cost. Only a magnetic sensor with tunnel magnetoresistance devices can satisfy all the demand in principle. As the device has very wide range of the sensing magnetic field, it can be designed for any demand to the sensors. Targeted Application(s)/IndustryFor example, this device can sense a bio-magnetic field easily at room temperature, so that it could be replaced SQUID device, which is popular now but is very expensive and not easy to use personally. Therefore, by using this device, we expect we can conduct effective collaborative research in medical field. Department of Applied Physics, Graduate School of Engineering
