Yet, while attracting great interest, the gas trade still employs relatively few ships in comparison to oil tankers, and hence its inner workings are little known...
متن کاملSome Researches on Histones
The histone extracted from calf thymus glands is a complex system of proteins, which can be fractionated by chromatography on carboxymethyl cellulose columns into three principal fractions (1) very lysine-rich, (2) moderately lysine-rich, (3) arginine-rich. When examined by starch gel chromatography each of these gives more than one band. Methods have been devised for further separation of the ...
متن کاملJet expansion module for liquid-sampled GC-discharge ionization detection of liquefied gases.
A rugged jet expansion module was designed, built, and utilized to sample liquefied gas for gas chromatography-discharge ionization detector (GC-DID) analysis. The module is inserted at an intermediate stage between a higher pressure sample cylinder and lower pressure gas injection manifold. The title jet module permits selection of liquid-phase or vapor-phase sampling by setting the valve-cyli...
متن کاملResearches on Ingeniously Behaving Agents
We have been studying the techniques for evolutionary robotics and experimenting with various robots applied evolutionary methods. We have paid special attentions to real robots and multi-agent problems with them. In this research domain, we named them as “Ingeniously Behaving Agents (IBA)”. This paper shows several techniques developed in our IBA laboratory and their experimental results appli...
