Provided is a physical quantity measuring method using a Brillouin optical fiber sensor. An optical fiber is set on a structure and a pair of pulse lights having different pulse widths is selected. The pulse lights are sequentially transmitted through the optical fiber to obtain back scattering lights and Brillouin gain spectra. The Brillouin gain spectra are compared to each other to calculate a normalized spectrum and a Brillouin frequency is acquired based on the normalized spectrum. The Brillouin frequency is multiplied by a conversion factor of a corresponding physical quantity of the structure to obtain the physical quantity. Accordingly, a portion of the optical fiber from which a sensing signal can be acquired is shortened to improve spatial resolution.

A cooling air supply apparatus of a refrigerator that is capable of uniformly supplying cooling air to all food received in a receiving box is disclosed. The refrigerator includes a refrigerating compartment and a freezing compartment for storing food at low temperature, a barrier for partitioning the refrigerating compartment and the freezing compartment from each other, and a receiving box mounted in the refrigerating compartment for receiving food. The cooling air supply apparatus includes a communication port formed through the barrier for guiding cooling air from the freezing compartment into the refrigerating compartment, and a hollow box-shaped cover mounted at the top part of the receiving box. The cover is provided at one side thereof with an introduction port, which communicates with the communication port. The cover is provided at the lower part thereof with at least one cooling air supplying hole, which communicates with the interior of the receiving box.
摘要:
The present invention relates to an apparatus for focusing particle beams using a radiation pressure capable of obtaining the same flow amount and a narrower particle beam width with respect to the particle size and a higher numeral density. It is possible to form the particle beams by applying the radiation pressure to the particles with respect to the flow condition that cannot form the particle beams with respect to the set particle sizes. There is provided an apparatus for focusing particle beams using a radiation pressure, comprising an orifice part that is provided at a predetermined portion of the flow tube, and a lens having a hole with a predetermined diameter for thereby focusing the particle flow into a particle beam and applying a radiation pressure to the flow particles; and a light source supply part (A) provided at a portion opposite to the discharge outlet of the mixing tube.

摘要:
Disclosed in certain embodiments is a golf training aid comprising a spheroid segment comprising a dimpled outer circumferential surface, a first substantially flat base surface, and a second substantially flat base surface, wherein the first substantially flat base surface and the second substantially flat base surface are substantially parallel to each other and are substantially equal in size.
摘要:
Described herein are inbred B6 ES cell lines that exhibit high developmental capacities and have a number of advantages over ES cell lines already available. First, they can be used for gene targeting and have a high percentage of germline transmission when injected into diploid host blastocysts (˜50-80%). Second, these ES cell lines can successfully be used to generate live pups by tetraploid blastocyst complementation, producing a high percentage (15-20%) of mice that are entirely inbred B6 ES cell derived. Third, these ES cells lines can be used to rapidly generate mice that are homozygous for a gene of interest. These advantages indicate that the inbred B6 ES cells provided here facilitate the rapid generation of inbred B6 mouse models in a cost-effective and efficient manner.
