This study presents a retrospectively reviewed consecutive series of fifty-one patients who underwent revision total hip arthroplasty through the anterior approach utilizing various Sapitinib extensions of this technique. The anatomic approach is discussed as well as problems as encountered in our series.”
“The L1(0) FePt phase material has potential applications for magnetic recording and permanent magnets due to its high magnetocrystalline anisotropy energy density. The heat treatment of [Fe/Pt](n) multilayer films is one approach to form the L1(0) FePt phase at a lower processing temperature, which is highly desirable for its applications.
This paper reports the influence of film total thickness (8-100 nm) on the structure and magnetic properties of annealed [Fe/Pt](n) multilayer MI-503 purchase films. A novel technique
based on hollow cone dark field transmission electron microscopy is used to determine the L1(0) phase fraction and grain size in the annealed films. It was found that the L1(0) phase fraction and grain size, ordering, and magnetic properties are strongly dependent on the total film thicknesses. An L1(0) FePt phase fraction close to 100% is achieved for a thick [Fe/Pt](n) multilayer film (100 nm) annealed at 400 degrees C for 1 h, while a value of only 36% is achieved for a thin film (8 nm) annealed at the same condition. In this work the L1(0) FePt phase nucleation density is also presented. These results suggest that the L1(0)
phase formation is nucleation limited, and that the subsequent growth of L1(0) phase grains also strongly influences the structure and magnetic properties of the annealed films. (C) 2009 American Institute of Physics. [DOI: Alpelisib ic50 10.1063/1.3073842]“
“Over the course of last two decades, surface plasmon resonance (SPR) has emerged as a viable candidate for label-free detection and characterization for a large pool of biological interactions, ranging from hybridization of oligonucleotides to high throughput drug-screening. Conventional SPR bio-sensing involves a step-response method where the SPR sensorgram in response to a switched sequential flow of analyte and buffer is plotted in real-time and fitted to an exponential curve to extract the associative and dissociative reaction rates. Such measurement schemes involve continuous flow conditions where a substantial reagent volume is consumed and is subject to dispersive mixing at flow switching zones. In this paper, we demonstrate a new plug-train SPR technique in a microfluidic chip that separates and singulates solvent plugs in analyte and buffer by an immiscible air phase. Bio-samples are first discretized within plug droplets with volumes in order of few hundred nanoliters or less followed by pressure-driven transport onto SPR sensing sites of this hydrophobically modified SPR microdevise.
