  A cycloolefinic resin composition of the invention comprises a thermoplastic resin comprising an alicyclic olefin polymer and a specified stabilizer selected from among phenolic stabilizers, organic thioether stabilizers, organic phosphite stabilizers, ultraviolet absorbers and hindered amine stabilizers. Since this composition contains a specified stabilizer, it is excellent in thermal aging resistance and weatherability and can be preferably used as the resin composition for making an optical member. The thermoplastic resin may also be one comprising both of an alicyclic olefin polymer and a flexible polymer, whereby especially the mechanical strengths are improved and a resin composition containing said resin is preferably used in the manufacture of machine parts, electronics components and automotive parts.

  The cycloolefin resin compositions of the present invention comprise a thermoplastic resin containing an olefin polymer having an alicyclic structure, specific stabilizers selected from phenolic stabilizers, organic thioether stabilizers, organic phosphite stabilizers, UV-ray absorbers and hindered amine stabilizers. The cycloolefin resin compositions show excellent thermal aging resistance and weathering resistance by the use of specific stabilizers, and therefore they are favorably used for forming optical instrument parts. Furthermore, the thermoplastic resin may be prepared from an olefin polymer having an alicyclic structure and a flexible polymer or flexible polymers. The incorporation of the flexible polymer especially improves the mechanical strength of the resultant products, and therefore the resin compositions are favorably used for machine parts, electronic parts, automobile parts, etc.

  A method for synthesizing concrete polycarboxylic acid water-reducing agent at room temperature under non-stirring situation is disclosed, which comprises dissolving reactive materials, initiator, chain transfer agent and promoter into a solvent, reacting on standing at 0-50°C; then adding neutralizing agent at the end of reaction. The method makes use of oxidation-reduction system reacting at low temperature, and can adapt to a variety of reactive material monomers. It does not need to control feeding speed or provide extra heating, does not need to stir during the reaction, and remarkably simplifies operation steps in traditional process, which makes it possible to not only produce in large scale, but also produce in small scale in concrete construction site at any moment.

  Provided herein are methods for identifying a compound that alters fluorescence resonance energy transfer (FRET) of a protein. In one embodiment, the method includes providing a target protein, where the target protein includes two heterologous domains, each domain having chromophores that together act as a FRET pair. In another embodiment, the method includes providing a target protein and a second protein, wherein the target protein includes a first heterologous domain including a chromophore, and the second protein includes a second heterologous domain including a chromophore, where the chromophores together act as a FRET pair. The method further includes contacting a sample including the target protein and optional second protein with a test compound to form a mixture, and measuring a fluorescence emission spectrum of the mixture during exposure to a light source. The fluorescence emission spectrum is decomposed into at least two component spectra, where in one embodiment the component spectra include a donor chromophore emission and an acceptor chromophore emission. A ratio (R) is then calculated, and in one embodiment, R is determined according to R = Acceptor   emission Donor   emission = bF A aF D .
