BACKGROUND Information describing variation in health outcomes for individuals with diabetes related foot disease, across socioeconomic strata is lacking. The aim of this study was to investigate variation in rates of hospital separations for diabetes related foot disease and the relationship with levels of social advantage and disadvantage. METHODS Using the Index of Relative Socioeconomic D...

Although acromioclavicular joint separations are fairly common, the occurrence of high-grade acromioclavicular separations that require surgery is low. Various modifications of the Weaver-Dunn procedure have been popular and fairly successful methods to treat severe acromioclavicular separations, despite the fact that reconstructions have been done a number of ways. We report on the results of ...

Using an analytical model, we compute the distribution of image separations resulting from gravitational lensing of distant sources, for 7 COBE-normalized CDM models with various combinations of Ω0 and λ0. Our model assumes that multiple imaging results from strong lensing by individual galaxies. We model galaxies as nonsingular isothermal spheres whose parameters are functions of the luminosit...

We prove a separation between monotone and general arithmetic formulas for polynomials of constant degree. We give an example of a polynomial C in n variables and degree k which is computable by an arithmetic formula of size O(k2n2), but every monotone formula computing C requires size (n/kc)Ω(log k), with c ∈ (0, 1). This also gives a separation between monotone and homogeneous formulas, for p...

There are 103 commercial nuclear power stations currently operating in the United States, generating a total of about 2 000 t of spent fuel each year. Over 40 000 t of spent fuel have accumulated since these plants began operation, with the fuel being stored first in at-reactor spent fuel storage pools and later in independent spent fuel storage installations and dry cask storage facilities. Th...

One of the problems encountered in CE separations of basic compounds is the adsorption of analytes onto the negatively charged capillary wall which could lead to poor repeatability of migration time and peak area. Additionally, separation of enantiomers of chiral of basic drugs is commonly carried out in low pH buffer which contributes to strong ionic interaction of the cationic drug ions with ...
