Aims: The Nova StatStrip blood glucose monitoring system was evaluated for precision, accuracy, and interferences from haematocrit and maltose. It was also compared against three other meters and two reference methods. Methods: Heparinised whole blood samples were analysed on the meters. These results were compared with whole blood samples analysed on the Radiometer ABL835 for the interference ...

Passwords are ubiquitous in our daily digital lives. They protect various types of assets ranging from a simple account on an online newspaper website to our health information on government websites. However, due to the inherent value they protect, attackers have developed insights into cracking/guessing passwords both offline and online. In many cases, users are forced to choose stronger pass...

BACKGROUND Point-of-care glucose meters are used increasingly in semi- and non-professional context. The quality of glucose measurements depends on the quality of the equipment, the quality of use, and the pre-analytical conditions. In this article, a External Quality Assessment Scheme (SKML)-Quality Mark for point-of-care test (POCT) and self-test glucose meters is proposed, assessing analytic...

BACKGROUND Recent evidence suggests that the frequency response requirements for peak expiratory flow (PEF) meters are higher than was first thought and that the American Thoracic Society (ATS) waveforms to test PEF meters may not be adequate for the purpose. METHODS The dynamic response of mini-Wright (MW), Vitalograph (V), TruZone (TZ), MultiSpiro (MS) and pneumotachograph (PT) flow meters ...

Cores of coral reef frameworks along an upwelling gradient in Panamá show that reef ecosystems in the tropical eastern Pacific collapsed for 2500 years, representing as much as 40% of their history, beginning about 4000 years ago. The principal cause of this millennial-scale hiatus in reef growth was increased variability of the El Niño-Southern Oscillation (ENSO) and its coupling with the Inte...

lin apparatus ,·,hieh could produce known amounts of angular momenlum in a pipeline was verified by direct measurement of axial and tangential velocity profiles. By using the assumption that a vortimetcr, with vanes spanning only the rotational core, responded to an equivalent solid rotational core, an expression was develop­ ed relating the angular velocity to the angular momentum. Comparison ...
