In an attempt to assess the level of quinolone resistance and its association with other antimicrobial resistance in faecal Escherichia coli isolated from routine outpatient specimens in Hong Kong, ciprofloxacin-supplemented MacConkey agar was used to screen for resistant isolates. Antimicrobial susceptibility testing of the isolates was done by VITEK 2 and(More)
We have produced ultrathin lead (Pb) nanowires in the 6 nm pores of SBA-15 mesoporous silica substrates by chemical vapor deposition. The nanowires form regular and dense arrays. We demonstrate that bulk Pb (a type-I superconductor below Tc = 7.2 K with a critical field of 800 Oe) can be tailored by nanostructuring to become a type-II superconductor with an(More)
The transition metal carbide superconductor Sc(3)CoC(4) may represent a new benchmark system of quasi-one-dimensional (quasi-1D) superconducting behavior. We investigate the superconducting transition of a high-quality single crystalline sample by electrical transport experiments. Our data show that the superconductor goes through a complex dimensional(More)
Industry platforms in the software sector are increasingly being developed in open source. Firms seeking to position themselves as platform leaders with such technologies must find ways of operating within the unique constraints of open source development. This thesis aims to understand those challenges by analyzing the Android and Hadoop ecosystems through(More)
The voltage–current (V–I) characteristics in superconducting monolayer FeSe film on SrTiO 3 (100) under different magnetic fields are investigated. The zero-field V–Iresult exhibits signatures of a Berezinski–Kosterlitz–Thouless transition, a characteristic of two-dimensional(2D)superconduc-tors. Under an applied magnetic field, with current density(More)
Sn is a classical superconductor on the border between type I and type II with critical temperature of 3.7 K. We show that its critical parameters can be dramatically increased if it is brought in the form of loosely bound bundles of thin nanowires. The specific heat displays a pronounced double phase transition at 3.7 K and 5.5 K, which we attribute to the(More)
