where 8, is the thickness of diffusant initially plated on the surface of the specimen, D is the diffusivity, and c(x, t) is atomic fraction of the diffusant at (x, t). This expression is appropriate if the diffusion anneal is long compared to mSo2/4Dc'„ where c, is the solubility of the diffusant. "' In some systems, this condition cannot be met. For example, in the study of the diffusion of z...

BACKGROUND Anterior C2/3 discectomy and interbody fusion (ACDF) with plating is increasingly performed as the primary treatment of unstable Hangman's fracture; however, plate-related complications, such as screw back-out, plate fracture and soft-tissue injury, is not uncommon. Polyetheretherketone (PEEK) cage has now been developed to provide initial stability before fusion; however, whether an...

The combination of plate and intramedullary nailing has been established as the treatment proximal tibial fractures. Nevertheless, at distal end tibia, application plate-assisted is rarely applied a therapeutic technique. authors provide technical note on use reduction plating technique for nail insertion management tibia fractures.

The ferrite plating a method synthesizing ferrite films from an aqueous solution -has developed lately as follows; (1) Applying power ultrasound to aqueous solution improves the qualities of ferrite coating on polymer microspheres much, (2) similarity is found between mechanisms of the ferrite plating and bacterial FesO4 ( magnetsome) synthesis, (3) using highly alkaline (pH=13) solution contai...

in the present study, ni-p-cnt composite coating was successfully fabricated via electroless plating. scanning electron microscopy (sem) was used to characterize the coatings. the effect of cnts concentration in the bath on its content in the composite coatings was studied. furthermore, the corrosion behaviour of the coatings with different contents of cnts was evaluated using tafel polarizatio...

Lightweight single-layer slotted waveguide array antennas are fabricated using plastic materials with metal-plating. A plastic material that has good heat-radiation properties is investigated. Three types of antennas are fabricated by milling, using ABS resin, heat-radiating plastic, and aluminum alloy. In measurements, all three types of antennas are confirmed to have almost the same VSWR and ...

Ten bacteriophages for Xanthomonas phaseoli were characterized. On the basis of adsorption rates, latent period and burst size, plaque morphology, host range, efficiency of plating, ultrastructure, sensitivity to osmotic shock, streptomycin sensitivity, temperature effects on plating efficiency, and serology, the phages were separated into at least three groups. Some of the phages were infectio...

Distal humerus fractures continue to be a complex fracture to treat. This article describes two surgical techniques that can be used to tackle these difficult fractures: Parallel plating and orthogonal plating. Both techniques have yielded excellent outcomes after open reduction and internal fixation; yet each has its own set of unique considerations. However, the key to successful treatment of...
