A recent tight-binding scheme provides a method for extending the results of first principles calculations to regimes involving $10^2 - 10^3$ atoms in a unit cell. The method uses an analytic set of two-center, non-orthogonal tight-binding parameters, on-site terms which change with the local environment, and no pair…

The human immunodeficiency virus type 1 (HIV-1) matrix protein forms a structural shell associated with the inner viral membrane and performs other essential functions throughout the viral life cycle. The crystal structure of the HIV-1 matrix protein, determined at 2.3 angstrom resolution, reveals that individual matr…

The flow of an electrically conducting fluid in an open channel in the presence of a strong magnetic field of oblique incidence to both the channel walls and the force of gravity is explored. This type of flow has possible applications to the protection of high heat flux surfaces in magnetic confinement fusion reactor…

Iron spectra were measured with the Physical Electronics Model 5400 x-ray photoelectron spectrometer using unmonochromated Mg Kα x-rays at three pass energy settings corresponding to analyzer energy resolutions of 1.34, 0.54, and 0.13 eV. The specimen is a high purity 0.25 mm thick iron foil that was obtained from Joh…

Full-thickness, circular, cutaneous wounds (4 cm diameter) were created on metacarpi and metatarsi of 5 horses. On day 6, all 4 wounds on each horse received a stored autogenous split-thickness sheet graft. Grafts were obtained from the horse's ventrolateral thorax with a pneumatic dermatome at the time the cutaneous…

XPS spectra of Pt black in the as received state showed O and C impurities along with Pt. An in situ treatment by O2 and H2 increased Pt intensity and removed a part of oxygen and carbon impurities. The quasihomogeneous model was used for quantitative evaluation applying atomic sensitivity factors published in the lit…

A molybdenum σ= 5 [001](310) symmetrical tilt boundary has been examined following carburization heat treatments. The resulting structure was studied by 400 kV high-resolution electron microscopy and compared with the structure of the pure boundary. It is shown that two different morphologies and carbide structures ex…

The surface emittance of fully oxidized copper is experimentally determined as functions of wavelength between 2-10 /tin, the direction between the normal and grazing angles, and the temperature between 400-700°C. Clean copper surfaces, heated and exposed to air, begin to oxidize immediately. After a sufficient heatin…

Abstract Aluminoxane catalysts and anionic initiators can polymerize 3‐butyrolactone, 3‐BL, to high molecular weight stereoregular polymers. With the racemic monomer, [R,S]‐3‐BL, anionic polymerization with alkali metal complexes can form syndiotactic polymers and aluminoxane catalysts can form either highly isotactic…

The orientation of an object is determined by rotation angle and rotation axis. In the case of randomly oriented nonsymmetric objects, the distribution of rotation axes is uniform. But symmetry destroys uniformity. An orientation of a symmetric object can be represented by different but symmetrically equivalent sets o…

Germanosilicate glasses exhibit a significant photosensitive response which has been linked to the presence of oxygen-deficient germanium point defects in the glass structure. Based on this correlation, a process which produces highly photosensitive thin films without the use of hydrogen exposures, has been developed.…
