Charged Dilatonic Black Holes in Gravity's Rainbow

In this paper, we present charged dilatonic black holes in gravity's rainbow. We study geometric and thermodynamic properties of black hole solutions. We also investigate the effects of rainbow functions on different thermodynamic quantities for these charged black holes in dilatonic gravity's rainbow. Then, we demonstrate that first law of thermodynamics is valid for these solutions. After that, we investigate thermal stability of the solutions using canonical ensemble and analyze the effects of different rainbow functions on thermal stability. In addition, we present some arguments regarding the bound and phase transition points in context of geometrical thermodynamics. We also study the phase transition in extended phase space in which cosmological constant is treated as the thermodynamic pressure. Finally, we use another approach to calculate and demonstrate that obtained critical points in extended phase space are representing a second order phase transition for these black holes.Comment: 17 pages with 9 captioned figures: Accepted in EPJ

People with learning disabilities and mental health problems: the impact of ethnicity

There is increasing awareness of the needs of people with learning disabilities from different ethnic communities. This paper focuses on the impact of ethnicity on the presentation of mental health problems. The main aim of the paper is to inform those planning and delivering mental health services for people with learning disabilities of the current evidence, in order to enable their practice to improve health outcomes for people from minority ethnic communitie

Supporting the complexity of managing information technology projects : application of living systems theory

University of Technology Sydney. Faculty of Engineering and Information Technology.The main objective of this research is motivated by the challenge of IT project failure in terms of cost overrun and time delays which is a common practice and is being investigated for years now. Increasing complexity of projects or an underestimation of the project complexity is one of the reasons for project failure, which is the main focus of this study. For this reason, the present work seeks to understand how to apply living systems theory as new lens to investigate and support the complexity of managing IT projects; where management is about “preparation and facilitation” of the project tasks. To achieve research objectives, this study defined management framework based on interpretation of the literature and elicitation of expert opinions through online questionnaire. This framework provide guidelines for project managers to map and study project management processes to identify important issues that leads project to complexity and failure. It also provides suggestion on how to deal with these issues. Through presentation of the framework and supporting guidelines during semi-structured interview with experts, this research investigates the applicability and appropriateness of the proposed approach. The outcomes of this research help project managers to identify important issues that might arise in the project and assist them on how to facilitate and prepare management processes. Academia’s can use the result of the project to develop tools to measure complexity in projects. With this measurement, they will be able to estimate project timelines and costs more precisely

In vivo evaluation of ziram induced acute toxicity on pathomorphology of broiler chicken

Fungicides are usually used in agriculture and often find their way in poultry feed. Therefore, a study was undertaken to study the in vivo effect of one such fungicide (ziram) induced intoxication on pathomorphology of broiler chicken. After 2 weeks of age the birds were given fungicide (Ziram) in feed as a single oral dose of 100 mg/kg body weight. Out of 10 birds, 3 died due to ziram intoxication (30% mortality rate). Birds that died rapidly showed pronounced neurological signs like convulsions. The carcasses of ziram intoxicated birds appeared dehydrated and their mucous membrane was pale in colour. Marked vascular congestion was observed in brain on gross examination. The livers showed congestion and haemorrhages with necrotic foci. Kidneys and lungs had ecchymotic haemorrhages and heart revealed gelatinization of pericardium, distention and pericarditis. Atrophy of bursa of Fabricius and thymus; hypertrophy of thyroid was found. Histopathological examination revealed neuronal degeneration and necrosis associated with mild gliosis in brain. Lungs, pericardium and epicardium had severe congestion and there was degeneration with separation of myofibers. Glomeruli were congested and frequently revealed hypercellularity. There were sinusoidal congestion and varying degrees of hepatocellular degeneration. Bursa revealed mild depletion of lymphoid cells in few lobules while as thymus showed hypoplasia with depletion of lymphocytes. Thyroid had mild mononuclear cell infiltration and caecum showed marked necrosis and denudation of the mucosa. In conclusion, the depletion of lymphoid tissue from lymphoid organs was suggestive of immunosuppressive and immunomodulatory effects of ziram toxicity in broiler chicken

Holographic Complexity and Fidelity Susceptibility as Holographic Information Dual to Different Volumes in AdS

The holographic complexity and fidelity susceptibility have been defined as new quantities dual to different volumes in AdS. In this paper, we will use these new proposals to calculate both of these quantities for a variety of interesting deformations of AdS. We obtain the holographic complexity and fidelity susceptibility for an AdS black hole, Janus solution and a solution with cylindrically symmetry, an inhomogeneous background and a hyperscaling violating background. It is observed that the holographic complexity depends on the size of the subsystem for all these solutions and the fidelity susceptibility does not have any such dependence.Comment: Slighly updated version.
