What's The Sleepgram Pillows Made Of ?, Jmes Modmd

jmes modmd

The spread texture of this pad is produced using 100% cotton, and Sleepgram pillow feels excessively delicate and light. A zipper traverses the side of the cushion enabling sleepers to effectively evacuate the spread when it's a great opportunity to be washed. Inside the spread are two separate pads shrouded in 100% polyester and loaded up with a cushy down-elective called poly microfiber. These internal pads are named with a blue marker, and a red marker, signifying delicate and medium firmnesses individcually. This enables the sleeper to blend and match cushion arrangements so as to alter firmness.Leave just the blue …


Matrix-Infrared Spectra Of Structural Isomers Of The Phosphorus Oxysulfide P4s3o, Zofia Mielke, Lester Andrews, Kiet A. Nguyen, Mark S. Gordon Dec 1990

Matrix-Infrared Spectra Of Structural Isomers Of The Phosphorus Oxysulfide P4s3o, Zofia Mielke, Lester Andrews, Kiet A. Nguyen, Mark S. Gordon

Mark S. Gordon

Photolysis of the P 4S3--03 molecular complex in solid argon with red light produced two sets of new infrared absorptions including terminal PO and symmetric P-S-P stretching modes, which are assigned to structural isomers of P4S30 with terminal oxygen at the apex and base phosphorus positions of P4S3. Further ultraviolet photolysis produced evidence for oxo-bridged P4S30 and a secondary product, P4S30 2.

Elastic Magnetic Electron Scattering From 'Ca, H Baghaei, A Cichocki, J B. Flanz, M Frodyma, Y Han, R S. Hicks, R A. Miskimen, Gerald Alvin Peterson, S H. Rokni Dec 1990

Elastic Magnetic Electron Scattering From 'Ca, H Baghaei, A Cichocki, J B. Flanz, M Frodyma, Y Han, R S. Hicks, R A. Miskimen, Gerald Alvin Peterson, S H. Rokni

Gerald Alvin Peterson

The elastic magnetic form factor of 41Ca has been determined by 180° electron scattering in the momentum-transfer range 0.9–2.0 fm-1. An analysis of the data indicates that the amplitudes of the M3 and M5 multipoles are quenched by factors of 0.57±0.16 and 0.68±0.07 relative to the simple shell model. In contrast, the magnitude of the M7 form factor is in good accord with this model. Calculations that include multiparticle-multihole configurations in the 1f7/2 and 1d3/2 subshells, first-order core polarization to higher excited orbitals, and meson exchange currents give reasonable agreement with the data for all multipoles. The rms radius of …


Higgs-Boson Production In Peripheral Heavy-Ion Collisions: Electromagnetic Production, Alec Schramm, Burndt Muller Nov 1990

Higgs-Boson Production In Peripheral Heavy-Ion Collisions: Electromagnetic Production, Alec Schramm, Burndt Muller

Alec J Schramm

Higgs-boson production via fusion of two virtual photons in nuclear collisions at energies of several TeV per nucleon is calculated. It is shown that although a trigger on quasielastic nuclear collisions suppresses the Higgs-boson production cross section, this mechanism could still provide a method for producing and detecting intermediate-mass Higgs bosons (MZ≲MH≲2MW).

A Small Area Simulation Approach To Determining Variation In Dental Procedure Rates, Paula Diehr Nov 1990

A Small Area Simulation Approach To Determining Variation In Dental Procedure Rates, Paula Diehr

Paula Diehr

All small area analyses need to compare the observed variability in rates to that expected by chance alone, but the expected variability is usually not known. This paper uses patient-level data for five dental procedures to simulate the distributions of the summary statistics that are usually generated in such studies. These statistics are found to vary greatly even under the "null hypothesis" that all dentists are using procedures at the same rates. The simulated dentist rates are compared to observed rates obtained in a different study. These findings illustrate problems that can occur in small area analysis studies, and emphasize …


Use Of A Preferred Provider Plan By Employees Of The City Of Seattle, Paula Diehr Nov 1990

Use Of A Preferred Provider Plan By Employees Of The City Of Seattle, Paula Diehr

Paula Diehr

Little is known about the use of services in a preferred provider organization (PPO). We studied a preferred provider arrangement between Pacific Medical Center and employees of the City of Seattle. In the second 12 months of this program 8,529 subjects submitted at least one claim; of these, only 420 (4.9%) ever used the preferred provider. Those who used the PPO at least once differed significantly from those who never used it on age, sex, employee/dependent status, and utilization in the previous year. Outpatient and total charges were higher for PPO users than for nonusers before and after control for …

Structure And Stability Of Hexacoordinated Sila Dianions, Mark S. Gordon, Marshall T. Carroll, Larry P. Davis, Larry W. Burggraf Oct 1990

Structure And Stability Of Hexacoordinated Sila Dianions, Mark S. Gordon, Marshall T. Carroll, Larry P. Davis, Larry W. Burggraf

Mark S. Gordon

The structures and stabilities of hexacoordinated silicon-containing dianions SiX6 2- have been investigated by using both ab initio (X= H, F) and semiempirical AMI (X= H, F, OH, Me, Cl) calculations. Both methods predict the hexacoordinated structures to be minima on the potential energy surfaces, although the semiempirical barriers for the reactions SiX6 2- -+ Six5- + x- appear to be rather overestimated based on the ab initio results for X = H, F. The positive charge on the central silicon atom actually increases as the number of ligands increases, and the role of d orbitals on that atom appears …

Theory Of Compositional And Magnetic Correlations In Alloys: Interpretation Of A Diffuse Neutron-Scattering Experiment On An Iron-Vanadium Single Crystal, J. B. Staunton, Duane D. Johnson, F. J. Pinski Sep 1990

Theory Of Compositional And Magnetic Correlations In Alloys: Interpretation Of A Diffuse Neutron-Scattering Experiment On An Iron-Vanadium Single Crystal, J. B. Staunton, Duane D. Johnson, F. J. Pinski

Duane D. Johnson

We describe a first-principles theory for compositional and magnetic correlations in alloys and compare the results of the theory with recent diffuse, unpolarized, neutron-scattering measurements on a single crystal of ferromagnetic Fe0.865V0.135. The nuclear cross section is described very well by the theory and we are able to connect the q-dependent structure to the underlying electronic structure of the alloy. The magnetocompositional and magnetic correlations also may be obtained for comparison to polarized measurements.


Theoretical Study Of Pseudorotation Of Pentacoordinated Silicon Anions: The Prototypical Sih5-, Mark S. Gordon, Theresa L. Windus, Larry W. Burggraf, Larry P. Davis Sep 1990

Theoretical Study Of Pseudorotation Of Pentacoordinated Silicon Anions: The Prototypical Sih5-, Mark S. Gordon, Theresa L. Windus, Larry W. Burggraf, Larry P. Davis

Mark S. Gordon

Ab initio and semiempirical calculations are used to analyze the minimum energy path for the pseudorotation of SiH5-. Both AMI and MP2/6-31++G(d,p) predict pseudorotation barriers of 2.4 kcal/mol. A decomposition of the projected vibrational frequencies along the path is used to assist in the interpretation of the process.


Predicted Enthalpies Of Formation For Silaethylene, Disilene, And Their Silylene Isomers, Jerry A. Boatz, Mark S. Gordon Sep 1990

Predicted Enthalpies Of Formation For Silaethylene, Disilene, And Their Silylene Isomers, Jerry A. Boatz, Mark S. Gordon

Mark S. Gordon

Enthalpies of formation of silaethylene (SiH2=CH2), methylsilylene (HSiCH3), disilene (SiH2=SiH2), and silylsilylene (HSiSiH3) are predicted by using the recently developed GAUSSIAN-! method for computing accurate molecular energies. The predicted enthalpies of formation of the silylenes are compared with enthalpies of formation determined from isodesmic reactions. Very good agreement is found between these two methods and improved values for the enthalpies of formation of silaethylene and disilene are suggested.
