Whitworth University is a private Christian liberal arts college located in Spokane, Washington, United States, that offers Bachelor's and Master's degrees in a variety of academic disciplines. The university, which has an enrollment of nearly 3,000 students, offers 60 undergraduate and graduate programs. Formerly Whitworth College, the board of trustees voted to change the institution's name to Whitworth University in 2006, which became effective July 1, 2007. Wikipedia.

Width-increased dual-pump enhanced coherent anti-Stokes Raman spectroscopy (WIDECARS) is a technique that is capable of simultaneously measuring temperature and species mole fractions of N2,O2,H 2, C2H4, CO, and CO2. WIDECARS is designed for measurements of all the major species (except water) in supersonic combustion flows fueled with hydrogen and hydrogen/ethylene mixtures. The two lowest rotational energy levels of hydrogen detectable by WIDECARS are H 2 S(3) and H2 S(4). The detection of these lines gives the system the capability to measure temperature and species concentrations in regions of flow containing pure hydrogen fuel at room temperature. © 2010 Optical Society of America.

A record of explosive eruptions over the last 1830 years reconstructed from a South Pole, Antarctica, ice core extends the coverage of volcanic history to the start of the first millennium A.D. The ice core dating by annual layer counting carries an uncertainty of 2% of the number of years from time markers, with the largest dating error of 20 years at the bottom of the 182 m core. Several aspects of the methodology of detecting and quantifying volcanic sulfate signals in ice cores are examined in developing this record. The new record is remarkably consistent with previous South Pole records. A comparison with records from several Antarctica locations suggests that the South Pole location is among the best for ice core reconstruction of volcanic records, owing to the excellent preservation of volcanic signals at the South Pole, the relatively low and uniform sulfate background, and the moderately high snow accumulation rates which allow for dating by annual layer counting. A prominent volcanic event dated at 531(15) A.D., along with evidence from other records, indicates that an unusually large eruption took place in the tropics and was probably responsible for the "mystery cloud" climate episode of 536-537 A.D. The date of 536 is suggested for a prominent volcanic signal that appears in the first half of the sixth century A.D. in ice cores, which can in turn be used as a time stratigraphic marker in dating ice cores by annual layer counting or by computing average accumulation rates or layer thicknesses with such markers.

By studying what comics and film theory suggest about selecting and sequencing images, both regular slideware users and students learning about multimodal communication can find ways to use the software more effectively, creating more productive relationships among their audiences, their slides, and their rhetorical goals. Though some, like designer Edward Tufte, have suggested that programs such as Microsoft PowerPoint are too flawed to be used effectively, it is possible to create rhetorically effective slide presentations that make excellent use of visual design and take audience response into account, a fact reflected in the commentary of professional presenters and designers like Seth Godin, Nancy Duarte, and Garr Reynolds. By joining their advice to the observations of visual communication theorists such as Lev Kuleshov, Roland Barthes, and Scott McCloud, it is possible to improve slideware presentations not only on a slide-by-slide basis but also at the level of the sequence, where multiple slides work together to convey meanings and create significant audience-speaker interactions. To take note of the family resemblances among slideware, film, and comics as sequential visual forms is to begin to unlock the greater potential of slideware applications like Microsoft PowerPoint. © 2012 Elsevier Inc.

Undergraduate biology labs often explore the techniques of data collection but neglect the statistical framework necessary to express findings. Students can be confused about how to use their statistical knowledge to address specific biological questions. Growth in the area of observational ecology requires that students gain experience in sampling design and the scope of inference relevant to observational studies. I developed a laboratory-based guided inquiry that illustrates these concepts by comparing ponderosa pine (Pinus ponderosa) trees in northeastern Washington State. This approach presents a hands-on experience whereby students apply the statistics they learn in the classroom to a field-based investigation, giving students an appreciation of the design and interpretation of observational studies in ecology. ©2015 by National Association of Biology Teachers.

A broadband dye laser pumped by a frequency-doubled Nd:YAG laser with a full width at half-maximum from 592 to 610 nm was created for the use in a dual-pump broadband coherent anti-Stokes Raman spectroscopy (CARS) system called width increased dual-pump enhanced CARS (WIDECARS). The desired broadband dye laser was generated with a mixture of Pyrromethene dyes as an oscillator gain medium and a spectral selective optic in the oscillator cavity. A mixture of Rhodamine dyes was used in the amplifier dye cell. To create this laser, a study was performed to characterize the spectral behavior of broadband dye lasers created with Rhodamine dyes 590, 610, and 640 and Pyrromethene dyes 597 and 650, as well as mixtures of these dyes. © 2011 Optical Society of America.
