Ventilated-associated pneumonia (VAP) is a major concern for hospitals and a major problem for ventilated patients in the intensive care unit. Included in the basics are hand hygiene, wearing gloves, endotracheal tube suctioning, head of bed at 30°, stress ulcer prophylaxis, turning patient side to side at least every two hours, and giving the patient a sedation vacation each morning. Beyond the basics included here are oral hygiene, oral suctioning, endotracheal tube cuff pressure, artificial humidification, the difference in practice between registered nurses and respiratory therapists, using the beach chair position and early mobilization, and the VAP bundle. The prevention of VAP becomes the focus for both nurses and respiratory therapists working with patients who are ventilated. © 2016 American Association of Neuroscience Nurses.

Detrital zircons from quartzites constrain the timing of deposition, provenance, and basin evolution of the Grenville supergroup in the Adirondack Lowlands. Three samples from the stratigraphic succession yield maximum depositional ages of 1284 ± 16 Ma to 1257.6 ± 16 Ma. Shifts in provenance from rifting (unimodal volcanic), carbonate platform (Laurentian interior), deepwater clastics (southern Adirondack arc), to final basin fill (Laurentian interior) are documented. The Trans-Adirondack backarc basin is one of several that opened at ca. 1.30 Ga, filled with thick carbonate-dominated sequences, and closed during the Elzevirian orogeny (ca. 1245-1220 Ma), terminating widespread extension across the leading edge of southeast Laurentia. © 2015 Geological Society of America.

Three-dimensional laser scanning is an advanced technology that uses latest laser measurement technique to obtain measurements at thousands of points per second. Land surveyors are adopting the technology because of the dramatic increase in productivity and relative ease of 3D presentation. Applications of terrestrial 3D laser scanning include topographic surveying, as-built surveying, facility management, 3D imaging and modeling, forensic investigation, environmental protection and restoration, historical preservation, and architectural design. A review of current two-year land surveying/geomatics programs around the country shows a lack of training opportunities for 3D laser scanning in community colleges. Recognizing die problem, the National Science Foundation's Advanced Technology Education program awarded a grant to Evergreen Valley College to develop a curriculum for implementation by EVC and other schools. The project involves surveying and engineering educators and professionals from several organizations. This paper presents a 3D laser scanning course developed as part of the NSF project. Issues related to the implementation of the course at Evergreen Valley College are discussed. Details about the lectures and laboratory activities are given.

This study investigates human dietary patterns and economic trends at the coastal site of Ancón, Peru during the Andean Middle Horizon (550AD-1000AD) using stable isotopic data from 32 individuals buried at the site. δ13C and δ15N results from human bone collagen and δ13C from human tooth enamel and bone carbonate indicate that inhabitants consumed a mixed diet composed primarily of marine protein and C4 resources, with only marginal reliance on C3 foods. Over time, Ancóneros appear to have relied more heavily on C4 resources, particularly maize, despite the fact that the crop could not have been grown locally. These results are notable given that C3 rather than C4 or marine foods dominate the site's archaeological record. These data suggest that Ancón's inhabitants either had access to more fertile land up-valley where maize could be cultivated successfully or that they engaged in trade relationships with their valley neighbours. A third possibility is that increased maize consumption at Ancón during the Middle Horizon resulted from Wari imperial influence and interregional exchange. Comparisons of δ13C values in enamel and bone carbonate from Ancón individuals indicate that δ13Ccarb-enamel values are significantly more positive than δ13Ccarb-bone values. This suggests that the diets of young children were systematically enriched in 13C compared to that of adults, perhaps as a result of nursing activity and/or differential dietary practices among various age groups at the site. © 2009 John Wiley & Sons, Ltd.

The Dirac equation electron is modeled as a helically circulating charged photon, with the longitudinal component of the charged photon's velocity equal to the velocity of the electron. The electron's relativistic energy-momentum equation is satisfied by the circulating charged photon. The relativistic momentum of the electron equals the longitudinal component of the momentum of the helically-circulating charged photon, while the relativistic energy of the electron equals the energy of the circulating charged photon. The circulating charged photon has a relativistically invariant transverse momentum that generates the z-component of the spin /2 of a slowly-moving electron. The charged photon model of the electron is found to generate the relativistic de Broglie wavelength of the electron. This result strongly reinforces the hypothesis that the electron is a circulating charged photon. Wave-particle duality may be better understood due to the charged photon model-electrons have wavelike properties because they are charged photons. New applications in photonics and electronics may evolve from this new hypothesis about the electron. © 2015 SPIE.
