A comparative study of high-field diamagnetic fluctuations in deoxygenated YBa2Cu3O(7-x) and polycrystalline (Bi-Pb)2Sr2Ca3O(10)

We studied three single crystals of YBa2Cu3O{7-x} with Tc= 62.5, 52, and 41 K, and a textured specimen of (Bi-Pb)2Sr2Ca2Cu3O10 with Tc=108 K, for H//c axis. The reversible data were interpreted in terms of 2D lowest-Landau-level fluctuation theory. The data were fit well by the 2D LLL expression for magnetization obtained by Tesanovic etal., producing reasonable values of kappa but larger values of dHc2/dT. Universality was studied by obtaining a simultaneous scaling of Y123 data and Bi2223. An expression for the 2D x-axis LLL scaling factor used to obtain the simultaneous scaling was extracted from theory, and compared with the experimental values. The comparison between the values of the x-axis produced a deviation of 40% which suggests that the hypothesis of universality of the 2D-LLL fluctuations is not supported by the studied samples. We finaly observe that Y123 magnetization data for temperatures above $T_c$ obbey a universal scaling obtained for the diamagnetic fluctuation magnetization from a theory considering non-local field effects. The same scaling was not obbeyed by the corresponding magnetization calculated from the two-dimensional lowest-Landau-level theory.Comment: 7 pages 5 figures, accept in Journ. Low Temp. Phy

PATIENT SATISFACTION EVALUATION ON HOSPITALS; COMPARISON STUDY BETWEEN ACCREDITED AND NON ACCREDITED HOSPITALS IN JORDAN

The research aim is to compare accredited and non-accredited hospitals in relation to patient's satisfaction in Jordan and to address the question if there is a correlation between patient's satisfaction and accreditation. The researchers adopt a quantitative methodology. T test was used to test the main hypotheses. Patient satisfaction was measured using the SERVQUAL scale (tangibility, reliability, responsiveness, assurance and empathy). 1000 questionnaires were distributed to stratified random sample of hospitals' inpatients. The results show considerable evidence that accreditation significantly improves patients' satisfaction. Accordingly, accreditation programs should be reinforced as a tool to improve health service quality

The State of the Animals III: 2005

In this third, all new, volume in the State of the Animals series, scholars and experts in animal protection examine the challenges facing companion animals, marine mammals, and nonhuman primates and review legal protection for animals here and abroad.https://www.wellbeingintlstudiesrepository.org/humspre/1002/thumbnail.jp
