Chondrosarcoma of the spine is rare; Single Inlet 3 way Water Valve it presents predominantly in very young males and presentation with neurological deficit is uncommon.Treatment of this type of tumour is mainly through surgery as adjuvant therapy is ineffective.En bloc resection of tumours in the spine are difficult although it remains the recomme
The double-layer charge can effectively improve the axial driving ability of explosives, which shows a considerable engineering application prospect in highly efficient damage warheads.Due to the complex wave structure produced by the overpressure detonation of a double-layer charge, a series of dynamic behaviors inside the shaped charge liner will
A long-standing debate regarding the dynamics of silo discharge revolves around the use of mono-dispersed circular or spherical grains in simplified two-dimensional models.It is well-known that granular systems composed of particles of the same size can generate crystal or quasi-crystal domains with specific structural and dynamic behaviors.Can thi
The traditional views about the Greeks in the Misc Roman Empire (i.e.Rome as the new leader of Hellenism, or Greek alienation within the Empire), are not enough to explain the complex process which transformed the Greeks into Romans.Firstly, a new overview is needed: when dealing with the new imperial identity, reciprocity between Rome and the prov
