摘要:
A thermoplastic copolymer having an excellent balance among properties such as coating resistance, color stability and fluidity and having high operability and productivity can be obtained by a method for producing a thermoplastic copolymer, comprising step (I) of supplying a monomer mixture (a) containing an aromatic vinyl monomer (a1) and a vinyl cyanide monomer (a2) to a complete mixing type reactor continuously to produce a copolymer (A) and step (II) of supplying the copolymer (A) continuously to a tubular reactor with a static mixing structure therein, which is placed in series with the complete mixing type reactor, and reacting the copolymer (A) to produce a copolymer (B).

摘要:
A process for continuously producing a thermoplastic copolymer, in which a copolymer (A) containing unsaturated carboxylic acid alkyl ester units and unsaturated carboxylic acid units is produced and in succession heat-treated to perform intramolecular cyclization reaction by dehydration and/or dealcoholization reaction, for producing a thermoplastic copolymer (B) containing glutaric anhydride units and the unsaturated carboxylic acid alkyl ester units. The obtained copolymer is excellent in heat resistance and colorless transparency and very small in foreign matter content.

Disclosed is a process for producing a thermoplastic copolymer, which comprises step of supplying a monomer mixture (a) to a loop reactor continuously to produce a copolymer (A), the monomer mixture (a) comprising an aromatic vinyl monomer (a1), a vinyl cyanide monomer (a2) and an N-substituted maleimide monomer (a3). The process enables the production of a thermoplastic copolymer which has an excellent balance among physical properties such as heat resistance, color and flow property, reduces the amount of bleeding that may cause mold staining during molding processing and has excellent handleability and productivity.

A Josephson quantum computing device and an integrated circuit using Josephson quantum computing devices which can realize a NOT gate operation controlled with 2 bits will be provided. The Josephson quantum computing device (1) comprises: a superconducting ring member (10) having a π-junction (6) and a 0-junction (7); and a quantum state detecting member (20) constituted by a superconducting quantum interference device arranged outside of the superconducting ring member, wherein a bonding and an antibonding state brought about by a tunneling effect between a |↑> and a |↓> state as two states degenerate in energy of the superconducting ring member (10) are regarded as quantum bits. The bonding and antibonding states as the quantum bits are read out by the quantum state detecting member (20). The two bit controlled NOT gate operation can be performed by the two quantum bits comprising said quantum bits.

摘要:
The invention provides a process for producing DNA nanocages, characterized by comprising a step of two-dimensionally assembling three types of oligonucleotides by hybridization to form tridirectionally branched double-strand DNA having self-complementary chains in the terminals, and a step of three-dimensionally self-organizing the resulting tridirectionally branched double-strand DNAs so as to consume all of the self-complementary terminals. Since the DNA nanocages according to the invention can easily be formed from DNAs by one-step procedure and include nanoparticles in the interior, the DNA nanocages are significantly effective for the development of functional materials using DNAs.
摘要:
The present invention provides a method and a reagent for detecting a digestive organ cancer, gastric cancer, colorectal cancer, pancreatic cancer, or biliary tract cancer patient by analyzing genes with expression levels (in peripheral blood) that vary in association with digestive organ cancer, gastric cancer, colorectal cancer, pancreatic cancer, or biliary tract cancer cases, compared with normal healthy subjects. Specifically, the method for detecting a digestive organ cancer, gastric cancer, colorectal cancer, pancreatic cancer, or biliary tract cancer patient based on expression profiles comprises obtaining the expression profile of at least one gene selected from the group consisting of probes corresponding to genes with expression levels (in peripheral blood) that vary in digestive organ cancer, gastric cancer, colorectal cancer, pancreatic cancer, and biliary tract cancer cases, compared with normal healthy subjects. The reagent for detecting digestive organ cancer, gastric cancer, colorectal cancer, pancreatic cancer, or biliary tract cancer contains nucleotides or partial sequences thereof consisting of the nucleotide sequence of at least one gene selected from the group consisting of probes with expression levels that vary in digestive organ cancer, gastric cancer, colorectal cancer, pancreatic cancer, or biliary tract cancer, or nucleotides containing sequences complementary thereto.
