An experiment in which a rotating magnetic field was used to drive current in a cylindrical device was *** driven current was of sufficient size to reverse the applied axial *** an equilibrium could equally well be termed a field reversed configuration(FrC).In this experiment the FrC lifetime appeared to be limited by the duration of the rotating field pulse(40ms)with no evidence of gross instabilities.

A theoretical rigid-plastic analysis for the dynamic shear failure of beams under impulsive loading is presented when using a travelling plastic shear hinge model which tabes into account material strain hardening. The maximum dynamic shear strain and shear strain-rate can be predicted in addition to the permanent transverse deflections and other parameters. The conditions for the three modes of shear failure, i.e., excess deflection failure, excess shear strain failure and adiabatic shear failure are analyzed. The special case of an infinitesimally small plastic zone is discussed and compared with Nonaka's solution for a rigid, perfectly plastic material. The results can also be generalized to examine the dynamic response of fibre-reinforced beams.

The basics are clear:climate is changing,it is caused by human activity and it is affecting everyone and everywhere now[1]. The good news is that we know what to do about it—we can stop global temperatures rising further if we stop emitting greenhouse gases. But because some sectors (such as agriculture or aviation)will have ongoing ‘hard-to-abate’ emissions,

Polycomb Group Proteins(PcG)are a family of epigenetic regulators responsible for the repression of an array of genes important in development and cell fate *** proteins complex to form two types of epigenetic regulators:Polycomb repressive Complex 1 and 2(PrC1 and PrC2).Although the mechanisms regulating PrC2 recruitment and activity in mammals remain poorly understood,recent work has identified a non-canonical PrC2 in mouse embryonic stem cells(mESC)with unique activities required for repression of PrC2 target genes and necessary for mESC differentiation and somatic cell *** we review the functions of PrC2 in embryonic stem cells and explore the role of the newly identified mESC specific PrC2 regulatory subunits Jarid2(jumonji,AT rich interactive domain 2),Mtf2(metal response element binding transcription factor 2)and esPrC2p48.
