Three-dimensional (3D) topological insulator (TI) has emerged as a unique state of quantum matter and generated enormous interests in condensed matter physics.The surfaces of a Memes 3D TI consist of a massless Dirac cone, which is characterized by the Z2 topological invariant.Introduction of magnetism on the surface of a TI is essential to realize
Tulisan ini bertujuan untuk memberikan gagasan baru mengenai sosok kepemimpinan tahun 2014.Wacana yang muncul saat ini hanya terkesan bagi-bagi kekuasaan antara satu partai dan partai lainya dalam satu koalisi, sementara perdebatan tentang cita-cita nasional masih menempati ruang-ruang sempit.Pertarungan gagasan-gagasan besar seharusnya yang harus
Ageratum has a complex circumscription, and recent studies have indicated its polyphyletism.The genus has been placed in the tribe Eupatorieae whose embryology is not fully known.Embryological data are conservative and important indicators of phylogenetic relationships and can improve family relationships.This study presents, for the Motion Racewor
On the Hactchets 29th of June, 2009 the derailment of a rail-tanker containing liquefied petroleum gas (LPG) in the Viareggio station produced a large cloud of flammable vapours, which ignited in a flash-fire, causing 31 fatalities and extensive property damage.The literature models applicable to the simulation of flash fires differ for the hypothe
