PURPOSE/OBJECTIVES To examine practice environments and outcomes of nurses working in oncology units or Magnet hospitals and to understand the association between the two. DESIGN Secondary analysis of survey data collected in 1998. SETTING Medical and surgical units of 22 hospitals, of which 7 were recognized by the American Nurses Credentialing Center Magnet program. SAMPLE 1,956 RNs, of...

We compared 6 adult mosquito traps for effectiveness in collecting Aedes albopictus from suburban backyards with the goal of finding a more suitable surveillance replacement for the Centers for Disease Control and Prevention (CDC) light trap. Trap selection included 2 commercial propane traps (Mosquito Magnet Professional trap and Mosquito Magnet Liberty trap), 2 Aedes-specific traps (Fay-Princ...

Electromagnetic field analyses were carried out to study the influence of coated-conductor magnetisation, i.e. the screening (shielding) current, on the field quality of a dipole magnet in a rotating gantry for hadron cancer therapy. The analyses were made on the cross section of a cosine-theta dipole magnet in a rotating gantry for carbon ions, which generated 2.90 T of magnetic field. The tem...

The next generation of particle accelerators will be one-of-a-kind facilities, and to meet their luminosity goals they must have guaranteed availability over their several decade lifetimes. The Next Linear Collider (NLC) is one viable option for a 1 TeV electronpositron linear collider, it has an 85% overall availability goal. We previously showed how a traditional Failure Modes and Effects Ana...

Introduction: Determination of type and location of trapped objects and endoscopic observations among children with foreign-body ingestion. Materials and Methods: We evaluated 105 endoscopic records of patients presenting with foreign-body ingestion from 2001–2011. Results: Button batteries were the most common objects removed (41%). The lower segment of the esophagus was the most common trappi...

Permanent magnet motors have been considered for a variety of applications due to their features such as high power density and high efficiency. One of the issues that should be investigated in the design of these motors is the demagnetization problem. Usually, the demagnetization analysis is carried out in a steady state, while demagnetization effect in dynamic condition is more considerable d...

Control systems for shakers are necessary to remove both shaker dynamics as well as coupling effects between the shaker and the structure under test. Little attention has been given to shaker control for nonlinear structures. This paper presents the design, implementation and results of a shaker controller for a horizontal, cantilevered beam subjected to a non-uniform magnetic field. The object...

Our specific aim was to investigate whether a local static magnetic field of a permanent magnet, of either pole, affects resting skin blood perfusion. This was done by measuring skin blood perfusion (SBF) by laser-Doppler in dorsum skin of 2nd and 4th fingers of the nondominant hands of 12 volunteers. Both fingers were first exposed to sham magnets, and then the 2nd finger was exposed alternate...

In response to a landmark civil rights ruling, the state of Connecticut has adopted models of choice-based interdistrict desegregation that appear to satisfy current legal constraints. In this paper, we focus on Connecticut’s interdistrict magnet schools, and estimate the effects these schools have had on student achievement. We use longitudinal data on individual student test performance and i...
