The extraction device used in rotating-disk sorptive extraction consists of a Teflon disk in which a sorptive phase is fixed on one of its surfaces. Depending on the configuration, the rotation axis of the disk device can be either perpendicular or parallel to its radius, giving rise to two different mass transfer patterns when rotating-disk sorptive extraction is applied in liquid samples. In ...

BACKGROUND Although there have been significant advances in network, hardware, and software technologies, the health care environment has not taken advantage of these developments to solve many of its inherent problems. Research activities in these 3 areas make it possible to apply advanced technologies to address many of these issues such as real-time monitoring of a large number of patients, ...

We summarize the fabrication, flight qualification, and dark performance of bolometers completed at the Jet Propulsion Laboratory for the High Frequency Instrument (HFI) of the joint ESA/NASA Herschel/Planck mission to be launched in 2009. The HFI is a multicolor focal plane which consists of 52 bolometers operated at 100 mK. Each bolometer is mounted to a feedhorn-filter assembly which defines...

This paper examines the use of market-share thresholds (safe harbors) in evaluating whether a given vertical practice should be challenged. Such thresholds are typically found in vertical restraints guidelines (e.g., the 2000 Guidelines for the European Commission and the 1985 Guidelines for the U.S. Department of Justice). We consider a model of resale price maintenance (RPM) in which firms em...

The aim of our study was to compare crank torque profile and perceived exertion between the Monark ergometer (818 E) and two outdoor cycling conditions: level ground and uphill road cycling. Seven male cyclists performed seven tests in seated position at different pedaling cadences: (a) in the laboratory at 60, 80, and 100 rpm; (b) on level terrain at 80 and 100 rpm; and (c) on uphill terrain (...

A distinctively uneven profile of intelligence is a feature of the autistic spectrum. Within the spectrum, Asperger individuals differ from autistics in their early speech development and in being less likely to be characterized by visuospatial peaks. While different specific strengths characterize different autistic spectrum subgroups, all such peaks of ability have been interpreted as deficit...

This paper offers a new theory of destructive competition. We compare minimum resale price maintenance (RPM) to retail market clearing in a model with a monopolistic manufacturer selling to competitive retailers. In both the RPM and Flexible-Pricing Games, retailers must order inventories before the realization of demand uncertainty. We find that manufacturer profits and equilibrium inventories...

Replacing the project manager (RPM) during IT project is a known phenomenon, but surprisingly, few studies have investigated the issue. To improve understanding of the situation in the IT field, we propose a research agenda that aims to provide IT professionals the means to sustainably manage RPM in IT projects. The research agenda is structured in line with the goals of theories in Gregor’s ta...

This contribution describes the usage of the ducted fan as a possible actuator of a multicopter vehicle. The measurements are focused on both dependence of forward thrust on current consumption and on dependence of forward thrust on RPM. The measurement results of the ducted fan are compared with the measurement results of a regular propeller. The dependence of actual efficiency on static thrus...
