Activation of the p53 protein can lead to apoptosis and cell cycle arrest. In contrast, activation of the signalling pathway controlled by the Kit receptor tyrosine kinase prevents apoptosis and promotes cell division of a number of different cell types in vivo. We have investigated the consequences of activating the Kit signalling pathway by its ligand Steel factor on these opposing functions ...

Abrasive flow machining also known as abrasive flow deburring or extrude honing, is an interior surface finishing process characterized by flowing an abrasive-laden fluid through a work piece. This fluid is typically very viscous, having the consistency of putty, or dough. In this paper, the main purpose of the process is to investigate the surface finishing of die steel with the use of abrasiv...

Medium Carbon Steel AISI 1045 has a wide variety of applications in vehicle component parts & machine building industry. Surface roughness and Material Removal Rate are the main quality functions in high speed turning of medium carbon steel in dry conditions. In this study, the optimization of two response parameters (Surface roughness and Material Removal Rate) by three machining parameters (c...

PURPOSE In the authors' experience, the color of silicone elastomer following polymerization in molds made of gypsum products is slightly different from the color that was matched in the presence of the patient, before the silicone is packed. It is hypothesized that the investing materials and separating media have an effect on the color during the polymerization process of the silicone. MATE...

In the aluminum die casting process, erosion, corrosion, soldering, and die sticking have a significant influence on tool life and product quality. A number of coatings such as TiN, CrN, and (Cr,Al)N deposited by physical vapor deposition (PVD) have been employed to act as protective coatings due to their high hardness and chemical stability. In this study, the wear performance of two nanocompo...

The content of vitamin D in pork produced in conventional systems depends on the vitamin D concentration in the pig feed. Both vitamin D3 and 25-hydroxyvitamin D3 (25(OH)D3) are essential sources of dietary vitamin D; however, bioavailability assessed by serum 25(OH)D3 concentration is reported to be different between the two sources. Furthermore, the relationship between serum 25(OH)D3 level a...
