Titanium matrix composites (TMC) represent a perspective materials category with potential applications in many important fields like aerospace constructions, automotive industry, ship structures, sports and households objects, and others. A titanium matrix composite is constituted of a titanium or titanium alloy – matrix and reinforcements materials, which are usually ceramics in form of parti...

Wide use of titanium alloys results from their unique physical and chemical properties 1 . Combination of low density and improved corrosion resistance with good plasticity and mechanical properties determines application of titanium alloys in such industries as aviation, automotive, power and shipbuilding industries or architecture as well as medicine and sports equipment. Despite numerous adv...

Dense deposit disease is caused by fluid-phase dysregulation of the alternative complement pathway and frequently deviates from the classic membranoproliferative pattern of injury on light microscopy. Other patterns of injury described for dense deposit disease include mesangioproliferative, acute proliferative/exudative, and crescentic GN. Regardless of the histologic pattern, C3 glomerulopath...

Carbon nanotubes (CNTs) have excellent chemical durability, mechanical strength and electrical properties. Therefore, there is interest in CNTs for not only electrical and mechanical applications, but also biological and medical applications. We coated titanium, a common material for dental implants, with multiwalled carbon nanotubes (MWCNTs). First, titanium was aminated and covered with colla...

The ions released from conventional and high-copper amalgams in contact with titanium were quantitatively analyzed in a 0.9% NaCl solution at 37 degrees C when the surface area ratio of titanium/amalgam was set up as 1/10, 1/1, or 10/1. The corrosion potentials of the amalgams and titanium were measured under the same conditions. Surface analyses on the amalgams were also employed using SEM wit...

and porcelain-fused-to-metal restorations instead of gold or silver alloys. This tendency seems to be the same a]1 over the world, However, the expanded use of nickel-containing base metal alloys in dentistry has raised questions concerning their biological s fety, namely, carcinogenic and sensitivity risks.i) On the other hand, since pure titanium or titanium-based alloys have excellent biocom...

ni-hard4 white cast iron is excellent wear resistant material and has been widely used in wearaffected equipment operated under extreme conditions, such as in mineral processing, cement, copper and iron manufacturing. in this study the effect of titanium addition (1.2, 0.7 and 0.2 wt.%) to the ni-hard 4 cast iron with the nominal composition of si= 1.5%, mn=0.5%, c=3%, p=0.05%, s= 0.05%, mo= 0....

Despite extensive research interest in the last decade, the banking literature has not reached a consensus on the impact of bank mergers on deposit rates. In particular, results on the dynamics of deposit rates surrounding bank mergers vary substantially across studies. In this paper, we aim for a comprehensive empirical analysis of a bank merger’s impact on deposit rate dynamics. We base the a...

in this research, the thin films of n-s doped titanium dioxide (tio2) were successfully prepared by simple sol-gel method in the presence of tetrabutylorthotitanate as a starting reagent. furthermore, titanium dioxide (tio2) was functionalized with thiourea. furthermore, n-s doped titanium dioxides (nsto) were fixed on glass balls by glass balls fixed-bed reactor system. besides, the effect of ...

There is a wide cross-country variation in the institutional structure of bank failure resolution, including the role of the deposit insurer. We use quantitative analysis for 57 countries and discussion of specific country cases to illustrate this variation. Using data for over 1,700 banks across 57 countries, we show that banks in countries where the deposit insurer has the responsibility of i...
