Biliary sludge may be a precursor of gall stones in man. The aim of this study was to determine the incidence of biliary sludge in a prospective study of 36 patients admitted to the intensive care unit for longer than two days. The presence of biliary sludge was determined by ultrasonography. Biliary sludge developed in 17 patients (47%), after a mean of 5.5 days in the intensive care unit. Pat...
Materials synthesis often provides opportunities for innovation. We demonstrate a general low-temperature (260°C) molten salt electrodeposition approach to directly electroplate the important lithium-ion (Li-ion) battery cathode materials LiCoO2, LiMn2O4, and Al-doped LiCoO2. The crystallinities and electrochemical capacities of the electroplated oxides are comparable to those of the powders sy...
Synergism of Saccharum officinarum (sugarcane) and Ananas comosus (pineapple) extract additives on the quality of electroplated zinc on mild steel in acid chloride solution was investigated experimentally at ambient temperature (*28 C). The experiments were performed at different plating times (15 and 18 min), additive concentrations (2, 2.5, 3 ml/50 ml of acid chloride solution), pH 5, tempera...
The fatigue behavior of Gray Cast Iron is affected to its microstructure, strength, ductility, residual stress and surface roughness etc.... In general, fatigue life increase as the magnitude of surface roughness decrease or the surface hardness increases by surface treatment. As the consequence of conducted high temperature oxidation in subsurface layer of cast iron pores have been creating, c...
The continuous and rapid increase of areal density in magnetic data storage systems required a continuous increase of the coercivity of the storage media. In order to be able to record on these everhigher-coercivity media, new soft magnetic materials for pole tips with increased magnetic moment had to be developed. Significant progress has been made during the last few years in electroplating a...
OBJECTIVES White spots and enamel demineralization around orthodontic brackets are among the most important complications resulting from orthodontic treatments. Since the antibacterial properties of metals and metallic particles have been well documented, the aim of this study was to assess the antibacterial effect of stainless steel orthodontic brackets coated with silver (Ag) particles. MAT...
