this paper considers the possibility of spontaneous transition of aracemic mixture (composed of equal amounts of two enantiomeric species, say l and d) into a monochiral state (in which only one enantiomer, say l, is present). transitions of this kind have been recently experimentally observed. a plausible approach to this phenomenon is a model put forward by frank, based on simple laws of chem...

background: 7-lif: mg,cu,p (gr-207a) is one kind of thermo-luminescent dosimeters (tld) which can be used in diagnostic radiology and radiotherapy applications. because of having suitable properties such as good sensitivity, small size and being tissue equivalent, thermo-luminescent dosimetry has been one of the most important techniques in medicine over many years. choosing a correct energy fo...

This paper gives an overview of the types of models available for analysing possible futures of the global economy.

Some lessons from recent history both theoretical and practical are used to demonstrate the usefulness of the models. Address Cor...
