Radiation-driven evolution of low-mass x-ray binaries and the formation of millisecond pulsars

Description: Recent data on low-mass X-ray binaries (LMXBs) and millisecond pulsars (MSPs) pose a challenge to evolutionary theories which neglect the effects of disk and comparison irradiation. Here we discuss the main features of a radiation-driven (RD) evolutionary model that may be applicable to several LMXBs. According to this model, radiation from the accreting compact star in LMXBs vaporizes'' the accretion disk and the companion star by driving a self-sustained mass loss until a sudden accretion-tur… more

Application of telerobotic control to remote processing of nuclear material

Description: In processing radioactive material there are certain steps which have customarily required operators working at glove box enclosures. This can subject the operators to low level radiation dosages and the risk of accidental contamination, as well as generate significant radioactive waste to accommodate the human interaction. An automated system is being developed to replace the operator at the glove box and thus remove the human from these risks, and minimize waste. Although most of the processi… more

Interface stability and defect formation during crystal growth

Description: Unidirectional solidification experiments have been carried out in organic crystals with the aim of improving our knowledge on the effects of constraints on the interface morphology and to increase our understanding of the growth of anisotropic materials. The experimental information shows that lateral constraints such as a sharp change in the cross-sectional area in the solid liquid interface path, can produce important changes in the microstructure if the interface morphology is planar, cellu… more

Gas-phase generations and rearrangement of silathiones, R sub 2 Si=S

Description: Three routes are explored for the generation of silathiones: (1) the retroene elimination of propene from allythiodimethylsilane and 1-allythio-1-hydrido-1,2,2,2-tetramethylsilane; (2) the reaction of silylene, Me{sub 2}Di, with carbon disulfide which is thought to form a transient 3-membered ring with CS{sub 2} and the elimination of carbon disulfide to produce diethylsilathione; and (3) the beta-elimination of bis(trimethylsilythio)dimethylsilane. All these methods are explored in some detail… more

Competing electron-electron/electron-phonon interactions and polyacetylene

Description: Using Lanczos exact diagonalization, we investigate the effects of the competition between the electro-electron and electron-phonon interactions in the context of the 1-D tight-binding Peierls-Hubbard Hamiltonian, studying various structural, optical, and vibrational properties of strongly correlated systems. We use polyacetylene as our experimental guide, and perform a parameter space search to determine the level at which a unique set of parameters can model this prototypical conducting polym… more

[Assessment of effects of surfactants in a heavy oil reservoir]

Description: During the past three months we have carefully negotiated a joint venture to implement a pilot for testing the two enhanced oil recovery processes developed at CLD Technology, Inc. The technical staff at CLD Technology, Inc. has decided to model the heavy oil reserve on the Cantleberry Lease, the Jasmin oil field in Kern County, California. Staff members have designed a new sand pack to represent one-eighth (1/8) of a one, ten-acre, five-spot well pattern that will represent the sands of the Ca… more

False color viewing device

Description: This invention consists of a viewing device for observing objects in near-infrared false-color comprising a pair of goggles with one or more filters in the apertures, and pads that engage the face for blocking stray light from the sides so that all light reaching, the user`s eyes come through the filters. The filters attenuate most visible light and pass near-infrared (having wavelengths longer than approximately 700 nm) and a small amount of blue-green and blue-violet (having wavelengths in th… more
