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....

Background and Aims: The seal provided by a root canal filling may be compromised by post space preparation. The aim of this study was to compare coronal microleakage around cast posts and prefabricated pins. Materials and Methods: Thirty-eight extracted single-rooted, maxillary human teeth were prepared with step back method and filled with gutta-percha and sealer. After removing 8 mm of coro...

Application of ceramic reinforcements is one of the effective and well-known ways to refine the microstructure of brittle metals such as magnesium. In this research, the influence of nano/micro particles of zirconia on the microstructure of cast AZ91 alloy was studied. At the first stage, nano and micro ZrO2 powders were blended through mechanical alloying procedure. In five specimens, the tota...

BACKGROUND Many traditional methods and commercially available products are available to prevent a wet cast, although there is a paucity of literature regarding the optimal strategy. METHODS Using a synthetic leg model, a short leg cast was applied and six different methods were tested. Group A (Glad Press'n Seal wrap), Group B (plastic bag with rubber band), Group C (plastic bag with duct ta...

BACKGROUND Screw loosening of implant restorations continues to be a complication in implant prosthodontics. Screw joints are subjected to a loss of initially applied torque because of friction and component misfit. It has been suggested that the loss of applied torque is less in machined metal abutments than in cast plastic abutments. PURPOSE This study compared the loss of applied torque (d...

Objects that serve as extensions of the body can produce a sensation of embodiment, feeling as if they are a part of us. We investigated the characteristics that drive an object's embodiment, examining whether cast-body shadows, a purely visual stimulus, are embodied. Tools are represented as an extension of the body when they enable observers to interact with distant targets, perceptually dist...

To evaluate the effect of inoculant addition on functionally graded microstructure of centrifugally cast Al-Mg2Si composites, two cylinders of Al-13.8 wt.% Mg2Si with and without the addition of 1 wt.% Al-5Ti-B inoculant were cast in a vertical centrifugal casting machine. The chemical composition, microstructures and microstructural phases of the different radial sections of the cast cylinders...

Background. Treatment options for lateral ankle sprains continue to evolve as advances are made in terms of techniques and materials. Objectives. This study was performed to evaluate clinical outcomes and satisfaction between two immobilization materials, semi-rigid cast, and elastic bandages. Methods. This study was a non-randomized controlled study. Fifty-four patients have undergone immobi...

The purpose of the current study was to investigate whether peptidyl-prolyl cis/trans isomerase NIMA-interacting 1 (Pin1) can interact with calpastatin (CAST) and regulate CAST/calpain2, under excessive glutamate conditions, and subsequently regulate necrosis in rat retinal neurons. Glutamate triggered CAST/calpain2-mediated necrosis regulation in primary cultured retinal neurons, as demonstrat...

Nodular cast iron insert will be used as the inner component of nuclear fuel disposal canister. The outer cover of the canister is copper tube of 50 mm nominal thickness. Nodular cast iron insert is cast around several steel channels, which also strengthen the structure. The mechanical properties of the cast iron insert will be tested according EN-1563 /1/. According the specifications 100% NDT...
