Bioabsorbable implants offer an attractive alternative to metallic implants to stabilize small bone fractures in the hand. Self-reinforced bioabsorbable miniplating for metacarpal fractures was studied in bones from cadavers and compared with standard metallic fixation methods. One hundred twelve fresh-frozen metacarpals from humans had three-point bending and torsional loading after transverse...

Posterior spinal plating devices have recently made a re-emergence as both stand-alone devices and for use in conjunction with anterior fusion. Yet, the structural integrity of the posterior elements to support loads throughout the spine and the impact of plating on posterior element strength has not been well characterized. This study aims to quantify the mechanical strength of the posterior e...

Anterior cervical plating is commonly performed to stabilize anterior cervical fusions. Modern plating options include dynamic plates, with screws that can either toggle within fixed holes or translate within slotted holes. Regardless of the plating system used, paramount to success and avoidance of complications with plated anterior cervical fusions are meticulous plating techniques, exacting ...

Background: Conventional fixation methods of posterior wall acetabular fractures feature the use of plating and lagscrews. However, fixation of posterior wall fractures with buttress plating alone offers potential advantages by avoidingthe hardware complications related to hardware placement through the wall fragment. The purpose of this study wasto examine if buttress plating...

background:  fractures of the distal third of the tibia are mostly associated with a fibular fracture that often requires fixation. the preferred treatment of distal tibial fracture is the minimally invasive percutaneous plate osteosynthesis  (mippo) procedure. however, there are no clear cut guidelines on fixation of the fibular fracture and currently most orthopedic surgeons use a plate osteo...

The plating industry is one of the main toxic chemicals consumers, which uses various chemicals, including solvents, acids, bases, cleansers, sophisticated organic ingredients, and metal salts of cadmium, nickel and chromium. Due to the growing production of industrial waste in spite of actions related to these wastes’ management, no comprehensive pattern was introduced at different levels. Thi...

Over the past few years, synthesis of nanostructured materials has received great interest in the technology due to its wide range of applications in biosensors, energy system, catalysis, and in self-assembly of supramolecular structures. Nanostructured platinum metals materials are very attractive because of their superior electrocatalytic performance than the blanket Pt electrode. Recently se...

Recently, nickel-tungsten (Ni-W) coatings have been investigated by many researchers as a corrosion-resistant, wear-resistant, and high-hardness layer. However, reinforcing particles is also used to form composite improve the performance of these coatings. Therefore, in this research work, Ni-W coating reinforced with CeO2 was formed electroplating method pulse current on pure copper metal. The...

This is an analysis of different approaches in the use of technology by Boeing and DoD to determine how they may have affected development time for the C-17 and the Boeing 777. Boeing’s focus on cost, schedule, performance, and market competition is contrasted to DoD’s focus on performance. The paper concludes that the mere existence of a technology should not obscure (a) the impact its maturit...

Objective:Mold contamination of cakes and the possibility of mold growth can pose a serious health problem. Bakery products include various ingredients, which regularly contain molds. These microorganisms on cakes can come from the air, contaminated packaging materials and other sources.Methods: In this study, a total of 500 fungal isolates representing 36 species, were identified from cake sam...
