Adverse events (AEs) occur in health care and may result in harm to patients especially in the field of surgery. Our objective was to analyze AEs in surgical patient care from a nationwide perspective and to analyze the frequency of AEs that may be preventable. In total 19,141 randomly selected admissions in 63 Swedish hospitals were reviewed each month during 2013 using a 2-stage record review...

An R plasmid, R100-1, was mapped previously (Yoshikawa, 1974) by transduction from an integratively suppressed Hfr strain to a recipient with a mutation in gene dnaA. By this method various types of transductants of plasmid R100-1 that exist autonomously or in the integrated state were obtained. Seventy-one such transductants were used in the present study to map gene inc, which is responsible ...

AES is the best known and most widely used block cipher. Its three versions (AES128, AES-192, and AES-256) differ in their key sizes (128 bits, 192 bits and 256 bits) and in their number of rounds (10, 12, and 14, respectively). In the case of AES-128, there is no known attack which is faster than the 2 complexity of exhaustive search. However, AES-192 and AES-256 were recently shown to be brea...

Thin films of tungsten nitride (WNx) were deposited by MOCVD from the single-source precursor Cl4(CH3CN)W(N Pr). Films were analyzed by X-ray diffraction (XRD), Auger electron spectroscopy (AES) and cross-section scanning electron microscopy (X-SEM), while the film resistivity was determined by four-point probe. Film growth rates ranged from 10 to 27 ( A/min within a temperature range of 450–70...

The optoelectronic properties of gallium nitride (GaN) have been well studied for decades, with results being translated to applications in solid state lighting and lasers, thermoelectricity, solar cells, power electronics, etc. However, the mechanical and tribological properties of GaN have been studied and understood far less than its optoelectronic properties. Our research aims to explore th...

Successful synthesis of stable MFe2O4 nanoparticles@C has been realized by applying the novel concept of using levulinic acid possessing carboxyl and carbonyl groups to facilitate the interaction with metal ions (M(2+) and Fe(3+)) and the carbon source (phloroglucinol) in the sol-gel polymerization method. All the samples have been characterized by XRD, SEM, FT-IR, TEM, HRTEM, ICP-AES, CHNS, an...

The hollow CuO@SiO2 spheres with a mean diameter of 240 nm and a thin shell layer of about 30 nm in thickness was synthesized using an inorganic SiO2 shell coating on the surface of Cu@C composite that was prepared by a two-step hydrothermal method. The obtained hollow CuO@SiO2 spheres were characterized by ICP-AES, nitrogen adsorption-desorption, SEM, TEM, XRD, H2-TPR, CO-TPR, CO-TPD and NO-TP...

Three hundred twenty zinc-air batteries representing four manufacturers (Energizer, Power One, Duracell, and Ray-O-Vac) and four cell sizes (10, 312, 13, and 675) were exposed in a salt spray fog apparatus for 2.5, 5.5, 24, 48, and 72 hours. At the conclusion of each exposure, the batteries were rated blindly for the presence of rust by four experienced audiologists using a four point rating sc...
