Nowadays, flexi-coil springs are commonly used in the secondary suspension stage of railway vehicles.Lateral stiffness of these springs is influenced by means of their design parameters (number of coils, height, mean diameter of coils, wire diameter etc.) and it is often suitable to modify this stiffness in such way, that the suspension shows vario
Abstract Background Metastases are the major cause of cancer-related morbidity and mortality.By the time cancer cells detach from their primary site to eventually spread to distant sites, they need to acquire the ability to survive in non-adherent conditions and to proliferate within a new microenvironment in spite of stressing conditions that may
Klippel-Feil syndrome (KFS) is associated with numerous craniofacial abnormalities but rarely with skull base tumor formation.We report an unusual and dramatic case of a symptomatic, mature skull base Evaporator Cover Clip teratoma in an adult patient with KFS, with extension through the basisphenoid to obstruct the nasopharynx.This benign lesion w

Large size growth of Zinc(tris) thiourea sulphate (ZTS) crystals has been successfully done through slow solvent evaporation technique in presence of l-Ascorbic acid (LAA).The possibility of any extra phase due to presence of LAA was ruled out through Tape Measurers structural analysis.The deviation in lattice parameters and shift in peaks position
