The ‘formability’ of sheet metal is a major keyword referring to process design in the forming industry. Higher formability could reflect lower production costs and time. Many studies have been carried out improve various ways, by using finite element method experimental approaches. In present research, new zoning lubricant technique proposed. stainless steel SUS304 square deep drawn box used a...

The (secondary) electron emission from multilayered Al$_2$O$_3$/TiN membranes has been investigated with a hemispherical collector system in scanning microscope for electrons energies between 0.3 and 10 keV. These ultra-thin are designed to function as transmission dynodes novel vacuum multipliers. Two different types, bi-layer tri-layer, have manufactured by means of atomic-layer deposition (A...

Uncemented modular cups are the preferred implants for primary total hip arthroplasty (PTHA). Cemented all-polyethylene cups are still popular in Europe; however, the high prevalence of radiographic loosening observed after the first decade of implantation in young patients and the concept of ‘cement disease’ collaborated to generate skepticism about the use of cement for acetabular fixation. S...

Doppler data generated with the Cassini spacecraft’s radio carrier waves at Xand Ka-bands can be used to determine the quadrupole moments of Rhea’s gravitational field. The resulting tri-axial field should be consistent with the assumption that Rhea is in tidal and rotational equilibrium. If so, we can construct interior models that are consistent with Rhea’s mean density of 1236 kg/m3, determi...

OBJECTIVES To eliminate the inconsistency in the nomenclature, to anatomically and definitively describe the topographic relationship of the temporal branch of the facial nerve to the fascial layers and the fat pads, and to create an effective algorithm to define the safest approaches and planes for surgical procedures in this area. METHODS The study was performed using 18 hemifacial cadaveri...

We report a prospective, stratified study of 60 PCA-cups and 60 RM-polyethylene cups which have been followed for a median time of 90 months, with annual radiography. The radiological migration of cups was measured by the computer-assisted EBRA method. A number of threshold migration rates from 1 mm in the first year to 1 mm in five years have been assessed and related to clinically determined ...

We describe a case of maculopathy consisting of macular retinoschisis and serous macular detachment occurring in a patient with an acquired enlarged optic disc cup, similar to the maculopathy observed in congenital optic nerve abnormalities, mainly optic nerve pits and colobomas, without vitreomacular traction nor angiographic leak. Pars plana vitrectomy with argon laser endophotocoagulation an...
