Pigmented villonodular synovitis of any joint in the extraarticular region is very rare. Its clinical and radiological differential diagnosis is difficult due to exhibiting findings of any soft tissue tumor. Here we report an extrarticular pigmented villonodular synovitis case of the hip of a five-year-old boy, with its radiological and histopathological aspects. The mass was completely extraar...

Behavioral measurements on the water maze show night blindness in albino mice but cortical recordings show no difference between pigmented and congenic albino mice. Consequently we have measured the absolute threshold in albino and pigmented mice using an operant method. The estimated threshold value is -5.3 log cd/m2 for albino mice and -5.5 log cd/m2 for the pigmented mice. We conclude that t...

In the paper the methodology and test results of field and laboratory corrosion tests of steel earthing rods with zinc galvanized coatings and copperbonded coatings are described. The corrosion rate and level of corrosion damage of earthing rods with two different protective coatings have been compared as well some conclusions related to reliability and assessment of technical “life time” of st...

Fluorescent and flame-retardant two-component waterborne polyurethane coatings were synthesized using 1,5-dihydroxy naphthalene, a halogen-free polyphosphate and a hydrophilic curing agent, and their properties were systematically characterized. The average particle sizes and zeta potential values were below 170 nm and −30 mV. Meanwhile, the multifunctional two-component waterborne polyurethane...

TiO2 coatings deposited using reactive magnetron sputtering and spray coating methods, as well as Agand Mo-doped TiO2 coatings were investigated as self-cleaning surfaces for beverage processing. The mechanical resistance and retention of the photocatalytic properties of the coatings were investigated over a three-month period in three separate breweries. TiO2 coatings deposited using reactive ...

TieSieN coatings are synthesized on titanium alloy (Ti6Al4V) by arc-enhanced magnetron sputtering and the microstructure and tribological properties are determined. The friction coefficient of the TieSieN coatings, which is smaller in human serum than ambient air, decreases gradually with Si contents. Protein gel electrophoresis shows that the small friction coefficient is due to adsorbed prote...

The aim of this study was to evaluate hydroxyapatite (HA) coatings produced by dynamic voltage during electrophoretic deposition (EPD). Dynamic voltages from 0 to 200 V were incrementally applied in three interims. The as-deposited coating was sintered at 800 degrees C and its properties evaluated. Structure and phase analyses of both as-deposited and sintered coatings were evaluated by scannin...
