    Get PDF
    Over the last three decades, treating health economics as an independent scientific discipline and providing specific treatment to the topics related to the economics of the health care sector have become more and more common. Currently, the field is so well established that it has appeared in the ordinary curriculum of most universities, and even if health economists are mainly to be found in the medical departments, the connections to economics proper are being strengthened, and the methodologies applied are getting refined. In this connection the paper highlights about the concept of health, why does health matter, relationship between health and Health Economics, and the justification of health economics

    The aim of this paper is to provide an analysis on the relationship between InformationTechnology (IT) usage, CRM and performance of bank (state bank group) in Bhubaneswar,Odisha, India. Most of the banks in INDIA are geared for comprehensive banking solutionswith extensive branch networks. Empirical data collection was done in the year 2012 andanalyzed with the theoretical data. A sample of 18 branches was selected using the nonprobabilitysampling technique. Perceptions of branch managers, staff members andcustomers were collected using a survey method. All 18 branches selected are of anequivalent grade according to the grading set by the bank. Three different types ofquestionnaires were designed for branch managers, branch staff and customers. Bothstructured and semi structured questions were included in the questionnaires with 7 pointlikert scale. Using bivariate correlation and linear regression, data analysis was done. Thelinear relationship between variables was measured by using Pearson’s correlation coefficient.The analysis suggested that IT usage has a positive linear relationship with financialperformance and quality performance of bank branches. Bank performance was found to havea correlation with factors such as staff attitude towards IT usage, IT literacy level of bankstaff and scope and complexity of the IT applications

    Biosubstitutes for dural closure: Unveiling research, application, and future prospects of dura mater alternatives

    Get PDF
    The dura mater, as the crucial outermost protective layer of the meninges, plays a vital role in safeguarding the underlying brain tissue. Neurosurgeons face significant challenges in dealing with trauma or large defects in the dura mater, as they must address the potential complications, such as wound infections, pseudomeningocele formation, cerebrospinal fluid leakage, and cerebral herniation. Therefore, the development of dural substitutes for repairing or reconstructing the damaged dura mater holds clinical significance. In this review we highlight the progress in the development of dural substitutes, encompassing autologous, allogeneic, and xenogeneic replacements, as well as the polymeric-based dural substitutes fabricated through various scaffolding techniques. In particular, we explore the development of composite materials that exhibit improved physical and biological properties for advanced dural substitutes. Furthermore, we address the challenges and prospects associated with developing clinically relevant alternatives to the dura mater

    Anomalous Quantum Diffusion at the Superfluid-Insulator Transition

    Full text link
    We consider the problem of the superconductor-insulator transition in the presence of disorder, assuming that the fermionic degrees of freedom can be ignored so that the problem reduces to one of Cooper pair localization. Weak disorder drives the critical behavior away from the pure critical point, initially towards a diffusive fixed point. We consider the effects of Coulomb interactions and quantum interference at this diffusive fixed point. Coulomb interactions enhance the conductivity, in contrast to the situation for fermions, essentially because the exchange interaction is opposite in sign. The interaction-driven enhancement of the conductivity is larger than the weak-localization suppression, so the system scales to a perfect conductor. Thus, it is a consistent possibility for the critical resistivity at the superconductor-insulator transition to be zero, but this value is only approached logarithmically. We determine the values of the critical exponents η,z,Μ\eta,z,\nu and comment on possible implications for the interpretation of experiments

    Black Holes at Future Colliders and Beyond: a Topical Review

    Full text link
    One of the most dramatic consequences of low-scale (~1 TeV) quantum gravity in models with large or warped extra dimension(s) is copious production of mini black holes at future colliders and in ultra-high-energy cosmic ray collisions. Hawking radiation of these black holes is expected to be constrained mainly to our three-dimensional world and results in rich phenomenology. In this topical review we discuss the current status of astrophysical observations of black holes and selected aspects of mini black hole phenomenology, such as production at colliders and in cosmic rays, black hole decay properties, Hawking radiation as a sensitive probe of the dimensionality of extra space, as well as an exciting possibility of finding new physics in the decays of black holes.Comment: 31 pages, 10 figures To appear in the Journal of Physics

    Intersecting black branes in strong gravitational waves

    Full text link
    We consider intersecting black branes with strong gravitational waves propagating along their worldvolume in the context of supergravity theories. Both near-horizon and space-filling gravitational wave modes are included in our ansatz. The equations of motion (originally, partial differential equations) are shown to reduce to ordinary differential equations, which include a Toda-like system. For special arrangements of intersecting black branes, the Toda-like system becomes integrable, permitting a more thorough analysis of the gravitational equations of motion.Comment: 17 pages; v2: cosmetic improvements, published versio

    Extended black holes in strong gravitational waves

    Full text link
    We describe a large class of solutions in pure gravity, dilaton gravity and supergravity corresponding to extended higher-dimensional black holes with strong (non-linear) gravitational waves propagating along their worldvolume. For pure gravity, the extended black holes are higher-dimensional analogs of the point-like Schwarzschild black hole in four dimensions. For supergravity, they are non-extremal p-branes. The gravitational waves can be both space-filling and localized around the worldvolume of the extended black holes. The solutions we present contain a large number of arbitrary functions of the light-cone time describing the amplitudes of different non-linear gravitational wave modes.Comment: 14 pages; v3: commentary and references extended, published versio

    Al2O3-based nanofluids: a review

    Get PDF
    Ultrahigh performance cooling is one of the important needs of many industries. However, low thermal conductivity is a primary limitation in developing energy-efficient heat transfer fluids that are required for cooling purposes. Nanofluids are engineered by suspending nanoparticles with average sizes below 100 nm in heat transfer fluids such as water, oil, diesel, ethylene glycol, etc. Innovative heat transfer fluids are produced by suspending metallic or nonmetallic nanometer-sized solid particles. Experiments have shown that nanofluids have substantial higher thermal conductivities compared to the base fluids. These suspended nanoparticles can change the transport and thermal properties of the base fluid. As can be seen from the literature, extensive research has been carried out in alumina-water and CuO-water systems besides few reports in Cu-water-, TiO2-, zirconia-, diamond-, SiC-, Fe3O4-, Ag-, Au-, and CNT-based systems. The aim of this review is to summarize recent developments in research on the stability of nanofluids, enhancement of thermal conductivities, viscosity, and heat transfer characteristics of alumina (Al2O3)-based nanofluids. The Al2O3 nanoparticles varied in the range of 13 to 302 nm to prepare nanofluids, and the observed enhancement in the thermal conductivity is 2% to 36%
