This paper reports a novel on-chip cellular force measurement method of single cells using Direct-Outer-Drive mechanism (D-O-D mechanism). This D-O-D mechanism enables high speed (1 kHz), high power (1 kN) and high accurate manipulation (nanometer-order) of Robochip (Robot-integrated microfluidic chip) and mechanical property measurement of single cells. We succeeded in mechanical property measurement...
A novel apparatus for multifaceted evaluation of arterial function was developed in which functions of endothelial cells and smooth muscle cells and the function of the artery as a conduit tube, i.e., mechanical properties were measured. A rigid airtight chamber with an ultrasound probe was attached to the upper arm to manipulate transmural pressure (TP) of the brachial artery by changing the pressure...
We have constructed a simple estimation method of the dependence to photosynthetic rate of the light intensity using semiconductor pH sensor. As the rearing environment is important for effective growth of plants, simple measurement method of the photosynthetic rate is desired. Plants in photosynthesis absorb carbon dioxide (CO2) and release carbohydrates and oxygen. As CO2 is readily soluble in water...
Ash deposition, called fouling, is one of major problems occurring in boiler that incinerates waste products as fuel. Ash deposition layer on heat transfer tube in a boiler causes not only heat transfer inhibition but also corrosion of the surface of heat transfer tube. Compared with pulverized coal combustion boiler, a concern of fouling becomes larger under waste incineration conditions due to their...
