Abstract: The present invention relates to a method for producing a protein, comprising an inspection process, wherein the inspection process comprises: a step of approximating an infrared absorption band derived from a protein appearing around 1500 to 1600 cm?1 or around 1600 to 1700 cm?1 in an infrared absorption spectrum of the protein, by one or more normal distributions, a step of calculating an index value indicating a degree of broadening of the infrared absorption band based on the normal distributions, and a step of comparing the index value with a predetermined threshold to select, as a good-quality product, a protein having a degree of broadening of the infrared absorption band that is smaller than the threshold.

Abstract: This is to provide a process for preparing a polycarbonate diol diacrylate from a polycarbonate diol and a vinyl acrylate compound without using a protonic acid or a metal component. This is a process for preparing a polycarbonate diol diacrylate which comprises reacting a polycarbonate diol represented by the formula (I) and a vinyl acrylate compound represented by the formula (II) in the presence of a hydrolase, and a polycarbonate diol diacrylate represented by the formula (III) having a terminal acrylated ratio of 97% or more.

Abstract: Disclosed is a biological molecule-immobilized carbon membrane which comprises a porous carbon membrane and a biological molecule (e.g., an enzyme) immobilized on the carbon membrane, wherein the porous carbon membrane has three-dimensional cancellous pores through which fluid can permeate. The carbon membrane can have a large amount of a biological molecule (e.g., an enzyme) immobilized thereon and can also have a higher level of enzymatic activity or the like compared to a conventional one. Therefore, the carbon membrane is useful as an electrode for a bio-sensor or a bio-fuel cell.

Abstract: A method of producing a polyoxalate resin including polycondensing a dialkyl oxalate represented by formula (2): wherein R represents an alkyl group having 1 to 4 carbon atoms, with a saturated aliphatic diol represented by formula (3): HO-A-OH, wherein A represents a divalent saturated aliphatic hydrocarbon group having 3 to 12 carbon atoms, in which polycondensation reaction product, the molar amount of the dialkyl oxalate [M1] and the molar amount of the saturated aliphatic diol [M2] satisfy relationship (I): 0.5?[M2]/[M1]<1 while controlling the total content of water in the starting reaction mixture to 2,000 ppm or less.

Abstract: A biodegradable polyoxalate resin having a high melt-formability by the formula: X?O-A-O—CO—CO?nY in which A=C3-C12 divalent aliphatic hydrocarbon group, X=H; R—OCOCO— or OHC— group, Y=—OR, —OAOH or —OAOCHO when X=H—, or —OR or —OAOCHO when X=R—OCOCO— or OHC—, R=C1-C4 alkyl, and is usable in a resinous composition with a poly(lactic acid) resin.

Abstract: The present invention is to provide a novel 5-iodo-4-phenethylaminopyrimidine derivative represented by the following formula (1): wherein R1 represents a halogen atom, a C2-4 acyloxy group or a hydroxyl group; R2 represents a hydrogen atom, a halogen atom, a C1-4 alkyl group, a C1-4 haloalkyl group, a C1-4 alkoxy group or a C1-4 haloalkoxy group; n is an integer of 1 to 3; and * represents an asymmetric carbon atom, useful as pesticides, a synthetic intermediate thereof and processes for producing these compounds, and pesticides containing the 5-iodo-4-phenethylaminopyrimidine derivative(s).

Abstract: A nozzle 22 is used for a torch 5 which effects arc welding in a shield gas atmosphere using welding wire 26 that is continuously supplied from a wire support 23 that extends in one direction. The nozzle main body is disposed around and is separated by a space from the wire support 23. Air blow adapters 24 are fixed to the outer side of the nozzle main body and serve to supply into the nozzle main body fluid for removing sputter, and they have air introduction passages 33 that are directed to the central tip end.
