Experiments are reported that explore the onset of motion bubbles in a model yield stress fluid, Carbopol gel. Starting from trapped spherical bubble gel, yielding limit for is obtained by gradually expanding via stepwise decrease pressure. Our results show at longer and thinner when they higher concentrated This suggestive link between shape size rheology material, particular elastic behaviour...

A cholesteryl de-esterifying enzyme found in partially purified preparations of alpha toxin produced by the Wood 46 strain on Staphylococcus aureus has been separated from other staphylococcal proteins and from alpha toxin by isoelectric focusing and gel filtration. Preparations of alpha toxin from Bi-Gel P-60 columns and of the cholesteryl esterase from Bio-Gel P-200 columns showed a high degr...

フィルム式多点圧力センサーと一軸圧縮試験機を用いた新規食感評価法を開発した．本食感評価法を用いると「つるつる感」，「ねっとり感」のような，広く普及している評価方法が確立されていないゲルの接触面での変形挙動に関わる食感を精度よく推定できた．また，標準試料のバラエティを増やすことで本評価法の推定精度が向上する場合があることが確認された．

Two-dimensional electrophoresis is a major separating technique for proteins in proteomics. Alignment of gel images is critical for intra-laboratory or even more difficult inter-laboratory gel comparisons. In the paper, we propose a novel iterative closest point (ICP) method for 2D-gel electrophoresis image alignment. The paper seeks to introduce an information theoretic measure as one part of ...

This paper demonstrates local pH measurement in a microchip using a pH-sensing gel-microbead. To achieve this, the gel-microbead made of a hydrophilic photo-crosslinkable resin was functionalized with the pH indicator bromothymol blue (BTB). The primary constituent of this photo-crosslinkable resin is poly(ethylene glycol). Gel-microbeads impregnated with BTB were obtained by stirring the mixtu...
