Carbonyl sulfide (COS) in air and dissolved in seawater was determined during a cruise in August 1999 in the Sargasso Sea in the northwest Atlantic Ocean. Dissolved concentrations at the sea surface displayed only a weak diel cycle with a mean of 8.6 + 2.8 pmol dm -3 owing to low abundance of photochemical precursors and high temperatures causing rapid hydrolysis. Depth profiles measured over t...

0.1 Challenge 1 If we consider that G(x, t) and W (x, t) are harmonic functions in time, then there exist functions g(x) and w(x) such that G(x, t) = g(x) cos(ωt) and W (x, t) = w(x) cos(ωt). Reeplacing these two expressions in the problem (1), we have that −ω2w(x) cos(ωt)− c2w′′(x) cos(ωt) = g(x) cos(ωt), which implies that −ω2w(x) − c2w′′(x) = g(x). On the other hand, the function W (x, t) sa...

BACKGROUND Core outcome sets can increase the efficiency and value of research and, as a result, there are an increasing number of studies looking to develop core outcome sets (COS). However, the credibility of a COS depends on both the use of sound methodology in its development and clear and transparent reporting of the processes adopted. To date there is no reporting guideline for reporting ...

CORBA is a standard proposed by the Object Management Group (OMG) that promotes interoperability between distributed object systems. Following the standardization of this object-oriented middleware, the OMG has specified a set of Common Object Services (COS) that are meant to serve as the building blocks of distributed CORBA applications. The COSes are specified using CORBA Interface Definition...

BACKGROUND In adult correctional facilities, correctional officers (COs) are responsible for the safety and security of the facility in addition to aiding in offender rehabilitation and preventing recidivism. COs experience higher rates of job stress and burnout that stem from organizational stressors, leading to negative outcomes for not only the CO but the organization as well. Effective inte...

BACKGROUND The COMET (Core Outcome Measures in Effectiveness Trials) Initiative promotes the development and application of core outcome sets (COS), including relevant studies in an online database. In order to keep the database current, an annual search of the literature is undertaken. This study aimed to update a previous systematic review, in order to identify any further studies where a COS...
