Polarization in p−p elastic scattering at high energies

Abstract

Some recent data on polarization in p-p elastic scattering are briefly surveyed and their characteristics reviewed. A new 28 GeV/c measurement of A, the analyzing power is presented. A few interesting theories are also briefly discussed. We plan more measurements of A soon and planto measure ANN when the polarized beam comes on at the A.G.S.

Light Absorption of Secondary Organic Aerosol: Composition and Contribution of Nitroaromatic Compounds

“…(16) Multiple studies have demonstrated the formation of secondary BrC through laboratory experiments. (9,(17)(18)(19)(20)(21)(22)(23)(24)(25) Laboratory-based chamber experiments suggest that a variety of factors impact the light absorption of SOA, including precursor composition (volatile organic compounds, VOC), (17) oxidants (e.g., hydroxyl radical, OH; nitrogen oxides NO X ), (20) aging, (9) and seed acidity. (25) These studies conclude that the SOA derived from the photo-oxidation of anthropogenic aromatic VOCs (e.g., toluene) has stronger light absorption than typical biogenic (e.g., α-pinene) SOA reaction products.…”

FEM-Analysis of the One-Dimensional Coupled Thermomechanical Problem of TiNi SMA

“…In Figures 3 and 4 comparisons of numerical results with experimental one, that presented in paper [4] are shown. The stress-strain curves are for element 1 (see Figure 1).…”

“…Equations (4) and ( 6 ) constitute field equations of the thermomechanical rate problem. They must be satlsfied identically at any time, in the whole volume of the investigated structure V and should be augmented with appropriate boundary and initial conditions:…”

“…Several authors (Ortin [6], Leo et al [3], Lin et al [4] and the others) reported on influence of the rate of strain during mechanical tests of SMA samples on the size and shape of hysteresis loop on o-E charts. All of them were unanimous to attribute this fact to heat exchange conditions during sample testing.…”

“…All of them were unanimous to attribute this fact to heat exchange conditions during sample testing. The paper [4] delivers valuable experimental data for TiNi alloy, theoretical discussion contained in the paper [6] is not concentrated on the dependence of o-E curves for CuZnAl on strain-rate. The theoretical model proposed in paper [3], while delivering theoretical investigation of the observed experimentally by the authors thermomechanical phenomena, does not seem to have broad range of application.…”
