    A review of theoretical publications on non-steady thermoelectrics is given. Review concerns different aspects of non-stationary and pulsed processes in thermoelectric materials and devices. Theoretical analysis of dynamic behaviour of thermoelectric devices, including analysis of small and large signals of thermoelectric generator, is given and details of concepts of quasi-equilibrium thermoelectricity are discussed as well. Special attention is paid to theoretical study of the non-routine regime of non-steady thermoelectricity—fast-time dependence of thermoelectric properties when material or device is well out of equilibrium. Theoretical findings of fast-time dependence give reason to believe that it can increase the output electrical power of thermoelectric generator compared to stationary regime of operation. We also present experimental results obtained with first non-stationary thermoelectric generator prototype, which was designed for operation in fast-time dependence mode. Several research teams are presently making and testing devices to confirm that more electrical power can be obtained in AC mode (AC frequency about hundreds of kHz) than in DC mode. Descriptions with an analysis are given

    Nuclear weapons: the state of play

    "The present report ... describes in detail the progress - or lack of it - on the commitments and recommendations of the 2010 NPT Review Conference, the 2010 and 2012 NSS, and the rather more ambitious ICNND, as at December 2012. Its publication in early 2013 is timed to assist the deliberation of the NPT PrepCom process, and it will be followed by a further updated volume in 2015, prior to that year's NPT Review Conference. While there are some other "report card" publications in existence, or in preparation, aimed at tracking particular sets of recommendations or the performance of particular groups of states, we believe that the present volume is the most comprehensive of its kind." - page xCopyright Information: "This publication may be reproduced in full or in part if accompanied with the following citation:Ramesh Thakur and Gareth Evans, eds., Nuclear Weapons:The State of Play (Canberra: Centre for Nuclear Non-Proliferation and Disar
