流れの中にある物体の抗力測定の一方法

In order to make an accurate measurement of the drag force of the immersed body against the stream, a simple device was devised by attaching the strain gauge on a steel plate. It has become clear that direct measurement of the drag force of the immersed body by use of the device is feasible, and also the value obtained by indirect measurement which has been employed in this laboratory must be revised by approximately 10%

Total synthesis of TMG-chitotriomycin based on an automated electrochemical assembly of a disaccharide building block

The total synthesis of TMG-chitotriomycin using an automated electrochemical synthesizer for the assembly of carbohydrate building blocks is demonstrated. We have successfully prepared a precursor of TMG-chitotriomycin, which is a structurally-pure tetrasaccharide with typical protecting groups, through the methodology of automated electrochemical solution-phase synthesis developed by us. The synthesis of structurally well-defined TMG-chitotriomycin has been accomplished in 10-steps from a disaccharide building block
