What Water Works for SWOSU?

Bottled water has become a staple of our fast paced lives. Between 2000 to 2008, the sales of bottled water in the United States doubled from $6.1 to$12.6 billion (“Bottled Water,” 2008). One of the major reasons that bottled water drinkers give for their preference is convenience. Alternatively, critics assert that bottled water hurts the environment, is overpriced, and is no safer than tap water. This raises the question: does taste or other less physiological factors such as cost and availability affect what water people choose to drink? A study conducted at University of Applied Sciences Hamburg sampled females on whether type of water affecd sensitivity to taste (Hoehl, Schoenburger, & Busch- Stockfishch, 2010). Researchers found most subjects tasted a sourness when sampling water containing minerals. Nordin, Razani, Markison, & Murphy (2003) reported older subjects to have a poorer ability to discriminate between taste intensities. These researchers also observed some gender differences. Therefore, the objective of our study was to determine whether taste, age, gender, cost and/or availability have an effect on what water that people at Southwestern Oklahoma State University (SWOSU) actually prefer

Precision measurements of A1N in the deep inelastic regime

We have performed precision measurements of the double-spin virtual-photon asymmetry A1A1 on the neutron in the deep inelastic scattering regime, using an open-geometry, large-acceptance spectrometer and a longitudinally and transversely polarized 3He target. Our data cover a wide kinematic range 0.277≤x≤0.5480.277≤x≤0.548 at an average Q2Q2 value of 3.078 (GeV/c)2, doubling the available high-precision neutron data in this x range. We have combined our results with world data on proton targets to make a leading-order extraction of the ratio of polarized-to-unpolarized parton distribution functions for up quarks and for down quarks in the same kinematic range. Our data are consistent with a previous observation of anA1n zero crossing near x=0.5x=0.5. We find no evidence of a transition to a positive slope in(Δd+Δd¯)/(d+d¯) up to x=0.548x=0.548
