Compared to conventional sheet forming operations, incremental (ISF) is a flexible technique that can achieve higher formability in terms of localized deformation. Due excellent mechanical properties and X-ray penetration, polyether-ether-ketone (PEEK) an ideal alternative titanium alloy stainless steel orthopedic applications. In this study, 3-axis desktop manufacturing system has been fabrica...

Titanium is an ideal material for use in prosthodontics because of its biocompatibility, corrosion resistance, and mechanical strength combined with its lightweight. Recently the use of titanium and titanium alloys for fixed restorations has increased substantially, mainly due to the improvement of techniques for the casting titanium and its alloys. This article reviewed the studies on titanium...

Abstract In the FFC-Cambridge process, cathodic dissociation of oxide and CO/CO 2 production on carbon anode is basis for metal in a CaCl bath. Using an inert intermetallic anode, CO evolution can be eliminated altogether with acceleration electro-reduction kinetics. presence TiO suffers from slow reduction kinetics to Ti metal, which enhanced significantly by incorporation alkali species pelle...

objective(s):anodized treated titanium surfaces, have been proposed as potential surfaces with better cell attachment capacities. we have investigated the adhesion and proliferation properties of h9c2 cardiac myoblasts on anodized treated titanium surface.  materials and methods: surface topography and anodized tubules were examined by high-resolution scanning electron microscopy (sem). control...

Titanium alloy sheet metal shows promising applicability in the aerospace industry with excellent mechanical properties, while its limited room-temperature formability is essential to be improved by thermal-assisted methods, expensive equipment and much energy consumption. In this work, flexible free incremental forming process adopted manufacture Ti6Al4V free-form surface panel at room tempera...

The use of fancy graphics can have a mesmerizing effect on simulation novices and, as such, may blind the user to the actual capabilities and valid usages. The visualization of simulations are distinct from other computer graphic media because they are a representation of an abstract of reality (the model) as opposed to a representation of reality. This extended abstract provides examples of vi...

This is a “cheat sheet”, which means that it consists of information packaged in a concise and efficient way so that it can easily be used as a quick reference. The topic is ranks of elliptic curves, mostly over Q. This is a slightly revised version of the handout I wrote as a supplement to my survey talk “Distributions of Ranks of Elliptic Curves” at MSRI’s Connections for Women: Arithmetic St...

titanium salts are widely used in pharmacy and industry as intensely white permanent pigment with good covering power in paints , paper , toothpaste , plastics and food dye s. this ion is a redox-active transition metal and may cause oxidative damages to lipids, proteins and dna molecules. in spite of abundant literature, questions about the side effects of titanium ions still remain to be answ...

INTRODUCTION Reconstruction of cranial defects is an essential component of skull base surgery as it aids in restoring functionality, providing coverage of intradural structures, and achieving optimal cosmesis. In acoustic neuroma surgery, tumor removal and subsequent reconstruction of the skull base defect are equally important elements. All three approaches utilized in acoustic neuroma surger...
