a 64-year-old woman, with amyloid related kidney failure (on renal dialysis) had a bone scan because of pain in the right upper femur. the 99m tc-mdp images revealed marked hepatic uptake. in addition, there was right proximal femoral concentration of radiotracer, which corresponded to a fracture site. as an added finding, the same femor demonstrated circumferential uptake at the lower pole. th...

Diamond-like carbon (DLC) thin films used in this study were prepared with DC magnetron sputtering deposition. Silicon (100) wafers were used as the substrates onto which an RF bias was applied during the film deposition. For the nitrogen doped DLC films, a pure graphite target was used as the carbon source and nitrogen gas was introduced into the deposition chamber via a mass flow controller. ...

in order to reduce both the weight of vehicles and the damage of occupants in a crash event simultaneously, it is necessary to perform a multi-objective optimization of the automotive energy absorbing components. in this paper, axial impact crushing behavior of the aluminum foam-filled thin-walled tubes are studied by the finite element method using commercial software abaqus. comparison of the...

Coating plays a significant role in surface engineering, which leads to the improvement of the mechanical and metallurgical properties of products. It also brings about economic benefits thanks to the cost savings of the improved properties of the surface of a product in particular. Friction surfacing is a relatively new way to create a homogeneous, fine-grained coating with amended resistance ...

Pulsed dc power supplies provide enabling capability to dielectric reactive sputtering applications due to their ability to reduce or even eliminate arcing during the deposition process. As this technology matures there has been increasing interest in the semiconductor, optical and industrial coating industries to use pulsed-dc sputter supplies for difficult to deposit films. The fundamental be...

Nanowire is a cylindrical nano-structure with nanometer dimensions. In this research, the studied nanowire was made from the magnetic triple Ni-Fe-Co alloy.&#10 We utilized ordered porous anodic aluminum oxide as a template for the nanowire deposition. The nanowire arrays were electrodeposited in the cylindrical pores of the oxide layer by AC potential in a simple sulfate bath. Then the relatio...

Aluminum toxicity in patients with chronic renal failure has been related to renal osteodystrophy and dialysis encephalopathy (DES). The toxicity is associated with renal osteodystrophy in two ways. One association is the iatrogenic effect of excessive use of aluminum hydroxide gels resulting in hypophosphatemia which interferes with bone mineralization. The second association may involve depos...

A polymer gel electrolyte using AlCl3 complexed acrylamide as a functional monomer and acidic ionic liquid based on a mixture of 1-ethyl-3-methylimidazolium chloride (EMImCl) and AlCl3 (EMImCl-AlCl3, 1-1.5, in molar ratio) as a plasticizer has been successfully prepared for the first time via free radical polymerization. Aluminum deposition is successfully achieved using a polymer gel electroly...
