Provided is a method for observing a dynamic physical property of a biological tissue by irradiating the biological tissue with a pulsed light having a wavelength of a far-infrared wavelength region to observe the dynamic physical property of the biological tissue using vibrational optical activity spectroscopy. When a sample which is the biological tissue is irradiated with a pulsed light, the biological tissue is vibrated. A relaxation time is obtained on the basis of a vibrational circular dichroism spectrum and/or a polarization spectroscopy spectrum which are/is obtained from a time-series signal of a reflected pulsed light reflected by the biological tissue or a transmitted pulsed light transmitted through the biological tissue.

Abstract: A high-capacity magnetic memory capable of writing and reading a magnetic record in/from a magnetic recording film according to a perpendicular magnetic recording system at a high speed in a purely-electrically random access manner. In the magnetic memory, a writing-magnetic-field generating means 62 and a writing word line 43 are disposed relative to a perpendicular magnetic recording film 50, and a reading/writing bit-line conductor 41, a magnetoresistive-effect element 20 and a reading word lead conductor 42 are laminated in order on a probe substrate opposed to the perpendicular magnetic recording film 50. A magnetic probe 30 composed of a carbon nanotube containing a soft magnetic material is disposed relative to the magnetoresistive-effect element 20 in a standing manner, and electrically connected to the reading/writing bit-line conductor.

Abstract: Disclosed herein is a method for determining the drug sensitivity of a microbe which comprises pouring a microbial suspension into each of the compartments or wells at a position which is in the vicinity of an electrode for measuring dissolved oxygen concentration, measuring current from each electrode at a second time interval for a third time period, each time is obtained based upon each of the measured currents at which the maximum current is obtained, obtaining each current value within a fourth time period which starts from the time at which the maximum current is obtained, detecting drug sensitivity based upon the variation condition of each current value during the fourth time period. The method allows rapid drug susceptibility measurements.

Abstract: An aqueous resin composition with gas barrier properties contains (i) polyurethane resin having aurethane group and a urea group in a total concentration of 25 to 60% by weight and having a acid value of 5 to 100 mgKOH/g, (ii) a swelling inorganic layered compound (e.g., a water-swelling mica, and a montmorillonite), and (iii) a polyamine compound having an amine value of 100 to 1900 mgKOH/g. The polyurethane resin (i) is obtained by a reaction of (A) an aromatic, araliphatic or alicyclic polyisocyanate, (B) a polyhydroxyalkanecarboxylic acid, and at least one component selected from (C) a C2-8alkylene glycol and (D) a chain-extension agent (e.g., diamine, hydrazine and a hydrazine derivative), and neutralized with a neutralizing agent. The proportion of the acid group of the polyurethane resin (i) relative to the basic nitrogen atom of the polyamine compound (iii) is 10/1 to 1/5 as the equivalent ratio.

Abstract: A method and apparatus wherein measurement current values output from a first oxygen sensor and a second oxygen sensor are time sequentially measured. Each moving average value is calculated from each sequential measurement current value. Each time differential value is calculated from the pair of each calculated moving average values, by least squares approximation. Then, drug susceptibility is measured based upon each calculated time differential value, so that drug the susceptibility measurement is performed quickly or accurately.
