components for the reconstruction of the acetabulum and metal femoral head components for conventional THA and RHA. The ACCIS®metal components are made of a chrome-cobalt-molybdenum alloy, but are different from other metal-on-metal prostheses. The surfaces of the metal components are engineered with the ceramic Titanium-Niobium-Nitride (TiNbN) in order to minimize metal particulate wear, to pr...

A new spectrophotometric method has been developed for determination of molybdenum using surfactantmediated liquid–liquid extraction. Molybdenum(V) obtained by ascorbic acid reduction in 2.5 M H2SO4 reacted spontaneously with thiocyanate and cetyl trimethyl ammonium bromide (CTAB), forming an intense orange yellow complex that was extracted quantitatively into 1,2-dichloroethane and absorbed at...

Microscopy and diffraction measurements are presented of ultrathin binary alloy films ruthenium molybdenum that obtained by standard sputter deposition . For compositions close to Ru 50 Mo , we find the be amorphous. The amorphicity is accompanied a significant reduction roughness with respect equally thick either or molybdenum. We ascribe this absence grain structure characteristic polycrystal...

Increased risk of ill-health and diseases has been associated with employment in the ferro-alloy factory. Since measurement of transition metals in human blood and hair along with respective exposure rates, provides a means of assessing individual risk, it has been the most important part of the study. In the study majority of the elements in the transition series, such as, vanadium (V), chromi...

Bone loss around femoral hip stems is one of the problems threatening the long-term fixation of uncemented stems. Many believe that this phenomenon is caused by reduced stresses in the bone (stress shielding). In the present study the mechanical consequences of different femoral stem materials were investigated using adaptive bone remodeling theory in combination with the finite element method....
