It has been calculated from kinetic measurements that the rate of the phosphorylase reaction is half-maximal when the glycogen concentration is 20 mg./lOO ml. (I). This K, (Micharlis-Menten constant) value can be expressed as a molar concentration, if the percentage of terminal glucose units (with which phosphorylase reacts) is known. For a glycogen with 9 per cent end groups, the K, would be 1...

This study aims to find out how the effectiveness of using a simple manual centrifuge as laboratory tool and teaching aid in science learning affects student outcomes at SMPN 14 Bengkulu City. The research method is included Quasi Experimental Design form Nonequivalent Control Group Design. Based on results testing hypothesis post-test data for experimental control classes calculation t test In...

Firstly, the main factors are obtained by use of dimensionless analysis. Secondly, the time scaling factors in centrifuge modeling of bucket foundations under dynamic load are analyzed based on dimensionless analysis and controlling equation. A simplified method for dealing with the conflict of scaling factors of the inertial and the percolation in sand foundation is presented. The presented me...

This article presents an analytical model, originally developed in the 1980s, for the gas centrifuge and uses this methodology to determine the main design and operational characteristics of several hypothetical centrifuge designs. A series of simulations for a typical first-generation machine is used to assess the relevance of important breakout scenarios, including batch recycling and cascade...

Polyribosome sedimentation velocity centrifugation can be used to identify differential regulation of the translation of mRNAs. However, ultracentrifugation presents practical limitations on the number of sedimentation velocity gradients that can be run simultaneously. A method for sedimentation velocity analysis of polyribosomes is presented that is based on low-speed centrifugation of sucrose...
