    Semileptonic Decays of Heavy Omega Baryons in a Quark Model

    Full text link
    The semileptonic decays of Ωc\Omega_c and Ωb\Omega_b are treated in the framework of a constituent quark model developed in a previous paper on the semileptonic decays of heavy Λ\Lambda baryons. Analytic results for the form factors for the decays to ground states and a number of excited states are evaluated. For Ωb\Omega_b to Ωc\Omega_c the form factors obtained are shown to satisfy the relations predicted at leading order in the heavy-quark effective theory at the non-recoil point. A modified fit of nonrelativistic and semirelativistic Hamiltonians generates configuration-mixed baryon wave functions from the known masses and the measured \lcle rate, with wave functions expanded in both harmonic oscillator and Sturmian bases. Decay rates of \ob to pairs of ground and excited \omc states related by heavy-quark symmetry calculated using these configuration-mixed wave functions are in the ratios expected from heavy-quark effective theory, to a good approximation. Our predictions for the semileptonic elastic branching fraction of ΩQ\Omega_Q vary minimally within the models we use. We obtain an average value of (84±\pm 2%) for the fraction of ΩcΞ()\Omega_c\to \Xi^{(*)} decays to ground states, and 91% for the fraction of ΩcΩ()\Omega_c\to \Omega^{(*)} decays to the ground state Ω\Omega. The elastic fraction of \ob \to \omc ranges from about 50% calculated with the two harmonic-oscillator models, to about 67% calculated with the two Sturmian models.Comment: 52 pages, 8 figure

    Integration of Value Management (VM) Process in Bangladesh: Disaster Management (DM) projects

    Over the past decades global leaders and communities’ attention have increased to the management of natural and human induce disasters because of significant intensity and frequency of disasters all over the world. Now a day’s disaster and its management have intersected and transcend country’s local boundaries and geographical area. From the time immemorial Bangladesh is one of the worst and wide varieties of disaster victim countries in this world which are tropical cyclones, floods, tornadoes, storm surges, river and coastal erosion, torrential rains, earthquake, droughts, epidemics and arsenic contamination. The main reasons behind this are - geographical location, multiplicity of rivers, land characteristics, coastal morphology and the monsoon climate. For that reason so many projects and programs are running in this country to face the problem and manage hazards. Critical learning from over decades with many programs and projects a mentionable initiatives “Comprehensive Disaster Management Program” (CDMP) in Bangladesh is a holistic collaborative effort of GoB, UNDP, DFID and a host of stakeholders. But overall result is still unsatisfactory. To overcome (DM) problems and establish an effective DM system in Bangladesh, it is important to evaluate current systems and projects structures. In contemporary world (VM) as a tool is now widely accepted for offering more values of the projects by engaging stakeholders at all stages of a project. VM always gives more emphasis on people’s participation from policy making to implementation. One of the most important matters in VM is quality assurance of project. Before initiating DM project, it also set plan or actions, workshops for feedback from all level stakeholders, assess needs, follow up meeting, training etc. to improve merit and adequate confidence about optimally fulfilling the customer’s expectation which carry out the spirit of VM.  VM tools and techniques are generally used by practitioners to instigate projects providing support and adding value. So, for establishing an effective DM system in Bangladesh integration VM techniques in different stages of DM projects is very much essential.

    Investigating the Communicativeness of Teacher-Learner Interaction by Focusing on Teacher Talk in a Turkish University English Preparatory Classroom Context in North Cyprus

    Get PDF
    This study aimed to provide an empirical background about the interaction pattern and teacher talk in the English classrooms of universities in North Cyprus. The results suggest that, the Turkish university classroom context in North Cyprus is still teacher-centered with little genuine interaction between the learners and the teachers

    Law of Murder under Islamic Criminal Law: An Analysis

    Get PDF
    Islam considers murder to be the most heinous crime against a person. The blood of a human being is sacred in Islam. Prophet Muhammad (SAW) reportedly stated that the first act of Allah on the Day of Judgment would be to punish murderers by making them suffer the torment of Hell. Prophet Muhammad (SAW) at his last pilgrimage declared that the blood of human being, their property and prestige are as sacred as the city of Haram of Makkah and the day of Arafah. Undoubtedly the greatest crime known to mankind is murder. It has been punishable under all systems of law since early in the history of mankind and throughout the ages up to the present. This article explores the law of murder and its punishment under Islamic criminal law. It also examines the origin of punishment and way of proving of Islamic criminal law of murder.
