We discuss the problem of counting the maximum number of distinct states that an isolated physical system can pass through in a given period of time—its maximum speed of dynamical evolution. Previous analyses have given bounds in terms of ∆E, the standard deviation of the energy of the system; here we give a strict bound that depends only on E−E0, the system’s average energy minus its ground st...

The elementary particle physics community in the United States is proposing the construction of a very high energy, high luminosity, proton-proton collider called the Superconducting Super Collider1 (SSC) The proposed SSC has a maximum energy of 20 TeV per beam, yielding a total energy of 40 TeV; and a maximum luminosity of 1033~m-2s-1. The design is based upon the use of 6.6 Tesla superconduct...

Fresh ripened Guavas were procured from entrepreneur’s field and were weighed, sorted, washed, lye peeled before crushing and sieving to get guava pulp for preparation of different products such as RTS, Nectar and guava bar. Physico-chemical properties (Total Soluble Solids (TSS) Acidity, Ascorbic acid Content (AAC), Thermal properties, Particle Size analysis) and microbial properties (bacteria...

BACKGROUND Mortality for liver resection has remarkably improved owing to multiple factors. We sought to determine the impact of the various types of fellowship training on patient survival after liver resection. METHODS Patients who underwent hepatic resection between 1995 and 2004 in either the Calgary or Capital health regions (Edmonton) of Alberta, Canada, were identified using ICD-9 and ...

The sources of the May 1202 and November 1759, M 7.5 Near East earthquakes remain controversial, because their macroseismal areas coincide, straddling subparallel active faults in the Lebanese restraining bend. Paleoseismic trenching in the Yammoûneh basin yields unambiguous evidence both for slip on the Yammoûneh fault in the twelfth–thirteenth centuries and for the lack of a posterior event. ...

We carried out Chandra observations of two low-luminosity low-mass X-ray binaries, 1RXS J170854.4–321857 and 1RXS J171824.2–402934, for which previously single X-ray bursts were detected with the Wide Field Cameras (WFCs) on board BeppoSAX. Both were detected in our Chandra observations in an actively accreting state three to eight years after the X-ray bursts, with 0.5–10 keV luminosities betw...

We estimated direct medical and nonmedical costs associated with a false diagnosis of tuberculosis (TB) caused by laboratory cross-contamination of Mycobacterium tuberculosis cultures in Massachusetts in 1998 and 1999. For three patients who received misdiagnoses of active TB disease on the basis of laboratory cross-contamination, the costs totaled U.S. dollars 32618. Of the total, 97% was attr...

The protein Mpn474 encoded by the mpn474 gene of the human-pathogenic Mycoplasma pneumoniae contains 1033 amino acids and has an isoelectric point of 4.79, which is caused by the large excess of glutamic acid residues (11 %). Although the protein lacks recognizable export signals we showed by immuno-electron microscopy that Mpn474 is surface exposed, covering the cell completely. By combining c...

We present a detailed investigation of atmospheres around accreting neutron stars with high magnetic field (B ∼> 1012 G) and low luminosity (L ∼< 1033 erg/s). We compute the atmospheric structure, intensity and emergent spectrum for a plane–parallel, pure hydrogen medium by solving the transfer equations for the normal modes coupled to the hydrostatic and energy balance equations. The hard tail...
