Stacked porous octahedral tin phosphate Sn(2)P(2)O(7) nanodisks, with a thickness and a width of 20 nm and 200 nm, respectively, were prepared from quenching hydrothermally prepared (SnHPO(4))(2).H(2)O at 600 degrees C. The first discharge capacity was 600 mA h g(-1) while the capacity retention, even after 220 cycles, was 93%.

BACKGROUND This study determined the accuracy of pure tone air conduction (AC) thresholds obtained using a synchronous telemedicine approach without a sound booth in a rural South African community. The global need for increased hearing healthcare currently far exceeds the capacity for delivering these services, especially in developing countries. A tele-audiology approach using a portable diag...

A medical system is complicated because it has many sub-modules and is connected with many kinds of other systems. Because software faults tend to occur in interoperation among modules, a safety-critical medical system should be tested strictly in terms of integration. At integration testing phase, there are too many execution path of software to test, that makes testing difficult. To deal with...

-Electromechanical wave propagation may affcet power system protective device operation. This paper discusses the testbed development to study the electromechanical wave propagation impacts on power system dynamic behavior, and consequently impacts on protective devices including overcurrent, distance, and out-of step relays. To have a better insight, a test bed to simulate electromechanical os...

UNLABELLED Experimental data have demonstrated that impaired antioxidant capacity is associated with increased levels of reactive oxygen species (ROS) production. ROS can cause inactivation of critical enzymes and induce denaturation that renders proteins nonfunctional. Total blood is continuously exposed to oxidative stress. The aim of the current study was to investigate the reduction of nitr...

OBJECTIVE To examine the effects of 12 weeks of twice-weekly intensive aerobic exercise on physical function and quality of life after subacute stroke. DESIGN Randomized controlled trial. SETTING Ambulatory care. PARTICIPANTS Patients (N=56; 28 women) aged ≥50 years who had a mild stroke (98% ischemic) and were discharged to independent living and enrolled 20 days (median) after stroke on...
