There is ongoing effort to discharge patients early after hip fracture surgery to reduce the medical and economic burden. We tried to find whether there is any related side effect, and discovered that early discharge, especially before 10 days after surgery, is associated with higher mortality.IntroductionThe aim of this study was to analyze the association between the length of hospital stay after hip fracture and 1-year mortality in older adults aged ≥ 65 years old.MethodsWe conducted ...

BACKGROUND: Renal transplantation is the best treatment for patients with end-stage renal disease. Although there is significantly increased risk of malignancy after renal transplantation, carcinoma of the native kidney is very rare, and moreover, the risk of endocrinologic malignancy after renal transplantation is lower than in the general population and adrenal cortical carcinoma extremely rare. We report a case of incidental renal cell carcinoma originating from a native kidney after ...

A new kind of polishing method for mirror surface using the electrorheological (ER) fluid is presented. ER fluid is colloidal suspension and stiffens into semi-solid when subjected to an electric field. In this study, the mixture of the ER fluid and abrasives is used as polishing slurry. When the ER fluid is placed at the interface between a part and a moving platen, the friction force increases with the applied voltage. Since the polymeric ER particles separating two surfaces attract ...

An up-to-date abrasive polishing process using electrorheological (ER) fluid, known as ER fluid assisted polishing, is potentially useful in the surface finish of three dimensional micro or meso-scale devices. For a more detailed understanding of this process, the electrostatic principle of how an ER fluid functions on the polishing is described. Dielectric particles suspended in a dielectric fluid are polarized with the application of an electric field, and they experience the dipolar ...

The effects of pulse current (PC) electrolysis during electrodeposition of black chrome oxide (Cr2O3) on the optical properties and surface microstructure of the solar selective coatings were investigated in this study. For this investigation, the new chromic-propionic acid bath solution has been prepared, and black chrome coatings were electrodeposited onto the bright nickel substrates from this solution using PC electrolysis. This method enabled us to achieve good optical properties ...
