Published 1996Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: The front-end Equipment Protection System (FE-EPS) at the Advanced Photon Source (APS) is a high reliability, fail-safe single-chain interlock and control system. It consists of an Allen-Bradley PLC-5/30 processor, local and remote I/O racks, monitoring and control panels, serial communication links, and field devices. Each front end is equipped with a dedicated EPS. The system monitors a variety of sensors (e.g., vacuum, cooling water, temperature, pneumatic pressure), and controls front-end (FE) photon shutters and UHV valves. The main functions of the FE-EPS are to guard the integrity of the storage ring vacuum against vacuum excursions in the FE and beam transport line, as well as to protect the front-end and beamline components from being damaged by synchrotron radiation. The FE-EPS interfaces to six other APS interlock and control systems. Information about FE interlocks and devices is displayed on UNIX machines using the EPICS software tool kit. The system design is presented. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: Matrices formed by subjecting methanol vapor diluted in argon/krypton mixtures to electron bombardment and subsequent matrix isolation (EBMI) reveal a new feature at 885.3 cm−1 which is assigned to the v3 fundamental of the triatomic cation (ArHKr)+. In samples containing about 5% krypton, the v3 fundamental of Kr2H+ is also observed in a predominantly solid argon environment. These assignments are supported by annealing experiments and by density functional theory calculations reported in a separate paper. Similar experiments with xenon diluted in argon yield infrared spectra showing the v3 and v3+v1 bands of (ArHXe)+, and v3 of Xe2H+ in predominantly argon environments. EBMI of methanol diluted in krypton in the presence of xenon gives rise to infrared bands assigned to the v3 and v3+v1 fundamentals and combination bands of both (KrHXe)+ and Xe2H+ isolated in predominantly krypton environments. The energetics and plausible mechanisms to the formation of these homogenous and mixed proton-bound rare-gas dimers are considered. © 1998 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: Density functional theory calculations have been performed on the various proton-bound rare-gas dimers Rg2H+ and (RgHRg′)+ (Rg=Ar, Kr, or Xe, and Rg≠Rg′) employing the BP86 method coupled with either a Gaussian split valence basis set (DZVP) or a numerical split valence basis set (DN**). The calculations with the DN** basis represent the first calculations in which correct qualitative agreement is obtained with respect to the trend in experimental data for the antisymmetric stretching wavenumbers of the three Rg2H+ cations. Good qualitative agreement is also obtained for the antisymmetric stretching wavenumber of the mixed-rare-gas species (ArHKr)+. For the xenon-containing mixed-rare-gas cations, the agreement with experimental wavenumbers is not good as is the case for the DZVP basis set with any of the aforementioned cations. This is believed to be due to the inability of these basis sets to predict some physical and chemical properties for these species. Quantitative agreement between theory and experiment with respect to the antisymmetric stretch of the Rg2H+ cations is improved when four radial argon atoms are placed at a fixed distance from the central H, intended to mimic the matrix environment. Based on these calculations, an inverse hydrogen-isotope dependence for the dissociation energy of these species is predicted. No center atom isotope dependence is predicted for the symmetric stretching vibration. Employing a polyatomic model, we have reanalyzed previously published combination band data for Xe2H+ and Xe2D+, and concluded that there is no evidence for an inverse isotope dependence for the symmetric stretching vibrations of these species. © 1998 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-9559Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract An extensive study of the propyne optically pumped laser is presented. 32 new far infrared and 8 new mid infrared outputs are reported, together with pump frequency offset data. Complete assignments of some far infrared transitions and partial assignments of the mid infrared outputs are given. Very strong interactions occur between the mid and far infrared laser transitions. These interactions are of vital importance in obtaining high output energies.Type of Medium: Electronic ResourceURL: -

Published 1993Staff ViewISSN: 1018-5054Keywords: Chemistry ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyPhysicsNotes: The calculation of the stress tensor from molecular simulations of atomistic model polymer systems employing periodic boundary conditions is discussed. Starting from the dynamical equations governing the motion of sites, correct double summation forms of the atomic and the molecular virial equations are derived, which are valid for flexible, infinitely stiff and rigid chain models even in the presence of interactions between different images of the same parent macromolecule. A new expression for the true instantaneous stress (flux of momentum through the faces of the simulation box) is derived and shown to exhibit large fluctuations when applied in molecular dynamics simulations. A new equation for the thermodynamic stress, cast exclusively in terms of intermolecular forces on interaction sites, is also derived. Application to Monte Carlo simulations shows that the molecular virial expression exhibits the smallest fluctuations among all stress expressions discussed, and thus allows computation of the thermodynamic stress with least uncertainty. A scheme is developed for the calculation of surface tension from intermolecular forces only.Additional Material: 13 Ill.Type of Medium: Electronic ResourceURL: -

Published 1995Staff ViewISSN: 0739-4462Keywords: juvenile hormone kinase ; tritiation ; HPLC ; Chemistry ; Food Science, Agricultural, Medicinal and Pharmaceutical ChemistrySource: Wiley InterScience Backfile Collection 1832-2000Topics: BiologyNotes: Juvenile hormone epoxide hydrolase (JHEH) and juvenile hormone diol phosphotransferase (JHDPT) were characterized from the Malpighian tubules of day 1 fifth instar Manduca sexta. An improved RP-HPLC assay is described for the major metabolites of (10R, 11S) juvenile hormone I: diol, acid, aciddiol, and diol-phosphate. JHEH is strictly associated with membrane fractions, while JHDPT is cytosolic. JHEH may be solubilized in active form by the nonionic detergents Thesit or MEGA-8. Separation of Malpighian tubule cytosol proteins using preparative isoelectric focusing yields two zones which contain JHDPT activity, at pl 4.8-5.1 and 6.8-8.2. The partially purified JHDPT from either zone requires both ATP and Mg2+ for activity, so this enzyme may be formally called either ATP:juvenile hormone diol phosphotransferase or juvenile hormone diol kinase (EC 2.1.7.3.). Metabolites more polar than JH I aciddiol and JH I diol-phosphate are generated in vivo from either [3H]JH I or [3H]JH I diol. © 1995 Wiley-Liss, Inc.Additional Material: 4 Ill.Type of Medium: Electronic ResourceURL:
