Finishing methods of machining superhard composite’s working elements based on cubic boron nitride BL group are considered. The results the microgeometry formation research cutting inserts’ surfaces during by free powders synthetic diamond, grinding wheels and a method vibro-magnetic-abrasive (VMAM) presented. It is shown that VMAM friction between abrasive particles result in microremoval mate...

When end use considerations preclude complete utilization of the multifunctional design capabilities of DuPont engineering plastics, components can be joined through a variety of relatively quick and inexpensive assembly techniques. Among them: press and snap fits, cold heading cementing self-tapping screws, heat staking and spin, vibration and sonic welding. There is still another method of jo...

The fastCAT application uses pre-calculated Monte Carlo (MC) CBCT phantom-specific scatter and detector response functions to reduce simulation time for megavoltage (MV) kilovoltage (kV) imaging. Pre-calculated x-ray beam energy spectra, optical spread deposition, phantom kernels are combined with GPU raytracing produce volumes. MV spectra simulated EGSnrc 2.5 6 MeV electron beams incident on a...

Plasmodium falciparum DNA, isolated from the merozoite stage, was cleaved with HindIII and cloned in pBR322 and lambda L47.1 vectors. Plasmid clones containing 13.4, 7.0, 4.3, 4.1 and 1.5 kb inserts were characterized in some detail. The inserts contain several repeating units of smaller size. Nucleic acid hybridization studies showed that the repeat element is present in the Plasmodium DNA at ...

A recently developed ultra-hard boride-based material, AlMgB14, has been fabricated into a standard cutting tool geometry (TPG-222) and tested using single-point turning of Ti-6Al-4V. The initial testing was conducted to compare this new cutting tool’s performance relative to a WC-Co cutting tool. During the tests the boride-based inserts suffered catastrophic failure for a wide range of cuttin...

The purposes of this paper were to discuss the perceived benefits of inserts and orthotics for sport activities and to propose a new concept for inserts and orthotics. There is evidence that inserts or orthotics reduce or prevent movement-related injuries. However, there is limited knowledge about the specific functioning an orthotic or insert provides. The same orthotic or insert is often prop...
