The long-range interactions of two atoms, of an atom and a dielectric wall, of an atom and a perfectly conducting wall, and of an atom between two perfectly conducting walls are calculated, including the effects of retardation, for Li using dynamic polarizabilities determined from highly correlated, variationally determined wave functions. PACS numbers: 34.50.Dy, 31.90.+s, 31.30.Jv Typeset usin...

eart pressure problems are encountered in retaining walls, bulkheads, sheeting and bracing in cuts,culverts, tunnels, and cofferdams. in many cases, the lateral pressure is determined by use of classical earth pressure theories, such as coulomb's, where the equilibrium conditions of a failure wedge of soil is considered. excessive dynamic lateral earth pressure on retaining structures resu...

We investigate the motion of fermions in the presence of an electroweak phase transition bubble wall. We derive and solve the Dirac equation for such fermions, and compute the transmission and reflection coefficients for fermions traveling from the symmetric to the asymmetric phases separated by the domain wall. PACS number(s): 12.15.Ji, 98.80.Cq

Abstract Aim Abdominal Wall Repair (AWR) is a surgical procedure with risk of bleeding during and after its performance. Patients who reject blood transfusion require strategies to avoid or increase the margin indication for transfusion. Materials methods We analyzed Jehovah's Witnesses patients underwent AWR in our hospital perioperative management aiming prevent fatal anemia allow performance...

We study domain wall dynamics in Permalloy nanowires excited by alternating spin-polarized current applied perpendicular to the nanowire. Spin torque ferromagnetic resonance measurements reveal that domain wall oscillations at a pinning site in the nanowire can be excited with velocities as high as 800 m/s at current densities below 10{7} A/cm{2}.

A characterization of the S. cerevisiae KRE6 and SKN1 gene products extends previous genetic studies on their role in (1-->6)-beta-glucan biosynthesis (Roemer, T., and H. Bussey. 1991. Yeast beta-glucan synthesis: KRE6 encodes a predicted type II membrane protein required for glucan synthesis in vivo and for glucan synthase activity in vitro. Proc. Natl. Acad. Sci. USA. 88:11295-11299; Roemer, ...

Existing data for soft magnetic materials of critical current for domain-wall motion, wall speed driven by a magnetic field, and wall electrical resistance, show that all three observable properties are related through a single parameter: the wall mobility μ. The reciprocal of μ represents the strength of viscous friction between domain wall and conduction-electron gas. And μ is a function of t...

PURPOSE The aim of the present study is to examine cell wall and septum thickening of methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant S. aureus (MRSA), and methicillin- and linezolid-resistant S. aureus (MLRSA) isolates by transmission electron microscopy to correlate the association of resistance mechanisms with major changes in the morphology of membrane or septum. ...

In this review, we discuss new insights in cell wall architecture and cell wall construction in the ascomycetous yeast Saccharomyces cerevisiae. Transcriptional profiling studies combined with biochemical work have provided ample evidence that the cell wall is a highly adaptable organelle. In particular, the protein population that is anchored to the stress-bearing polysaccharides of the cell w...
