Response Functions of Quark-Gluon Plasma

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Study of quark-gluon plasma(QGP) has gained a lot of attention since last three decades. It is expected to be one of the most important and non trivial phase of hadronic matter under extreme conditions. In this monograph the response functions of QGP and their applications are studied in detail. This monograph contains an elementary introduction of QGP, basics of kinetic theory, coherent states in construction of the distribution function in phase space. A framework to determine the response functions of QGP is fixed. The explicit forms of the response functions for quarks as well as gluons for the ideal and non-ideal plasma are obtained separately. It is found that the response functions have two components: (i) Abelian and (ii) non Abelian. If the non Abelian interaction is switched off the non Abelian component vanishes. The response due to the gluonic component shows a richer structure in which it also possesses color tensor excitations. The static heavy quark potential and screening in QGP are analysed. The melting temperatures of heavy quarkonia are obtained. The Abelian and non Abelian components of response functions show two separate kind of Landau damping. ····· 10361134355

To establish a nuclear data group for medical applications in Pakistan is the major aim of our group. The idea of establishing such a group was given by Prof. Dr. Dr. h.c. (mult.) Syed M. Qaim (Professor of nuclear chemistry, institute für Nuklearchemie, Forschungszentrum Jülich, Germany and Hon. Professor of Physics at GCU Lahore). International collaboration has been established with the Institute of Experimental Physics, University of Debrecen (Hungary). EMPIRE training was arranged for nuclear model calculations at the headquarters of the International Atomic Energy Agency (IAEA). Now, the aim of involving the local bodies in multidisciplinary applications of nuclear data is in the way. The nuclear reaction cross section data relevant to the production of radionuclides in cyclotrons and at accelerators need more attention. The radionuclides are in practice for diagnostic and therapeutic purposes. The tumors are successfully detected by the emitted radiations and then the therapeutic techniques are adopted for their treatment. Nuclear science is for the peace of mankind. ····· 10361134287

A Proton Recoil Telescope for Neutron Spectroscopy

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
A new proton recoil telescope (PRT) is presented: it is composed by an active multilayer of segmented plastic scintillators as neutron to proton converter, by two silicon strip detectors and by a final thick CsI(Tl) scintillator. Plastic scintillators and silicon detectors are used to track the recoil proton and to measure the scattering angle, while the silicon strips and the final CsI scintillator can measure the proton energy: from these data it is possible to get the neutron energy. The PRT can be used to measure neutron spectra in the range 2-160 MeV. The detector characteristics have been studied in detail with the help of Monte Carlo simulations. The overall energy resolution of the system ranges from about 20% at the lowest neutron energy to about 2% at 160 MeV. The global efficiency is about 3x10^-5. Experimental tests have been performed by using the reaction 13C(d,n) at 40 MeV deuteron energy. ····· 10361134116

This timely book presents an assessment of heavy metal pollution in surface soils of an industrial cluster in Ghana, West Africa. It employs Energy-Dispersive (ED) X-Ray Fluorescence Spectroscopy, a nuclear analytical technique, for the qualitative and quantitative elemental analysis of soil samples. The book however, is aimed to investigate the extent of heavy metal pollution and distribution as well as to verify any significant industrial impact. Concentrations of nine (9) heavy metals (Zn, Pb, Cr, Cu, Co, Ni, Cd, Hg, and As) were measured and critically analyzed. These measured concentrations for each heavy metal were however compared to their respective threshold limit values (TLVs). The Particle-Size Distribution (PSD) analysis for the various sampled soils were also analyzed to verify any possibility of heavy metal seepage or infiltration, to establish any further possibility of underground water pollution. ····· 10361134046

Cylindrical detector and preamplifier design for detecting neutrons

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Tissue equivalent proportional counters are frequently used to measure dose and dose equivalent in mixed radiation fields that include neutrons however, detectors simulating sites 1µm in diameter underestimate the quality factor, Q, for low energy neutrons because the recoil protons do not cross the detectors. Proportional counters simulating different site-sizes can be used to get a better neutron dose equivalent measurement since the range and stopping power of protons generated by neutrons in the tissue-equivalent walls depend on the energy of the primary neutrons. The differences in the spectra measured by different size detectors will provide additional information on the incident neutron energy. ····· 10361133055

Aspects of Quantum Field Theories on Lattice

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
This book is intended for a beginner in Lattice Gauge Theory or even an outsider willing to get a quick glimpse of the subject. It provides a quick and simple outline of the nonperturbative formulation of Quantum Field Theory using a space-time lattice and Monte Carlo Simulation techniques. The introduction comprising the first twenty pages or so constitute the most useful part of this work where the basic formalism and its logical basis is briefly outlined with due emphasis on the extraction of continuum limit and connection to phenomenology. The rest of the book serves to provide illustrations, in rather simple and familiar settings, of how some of the aspects of the formalism are carried out in practice. The reader will also, hopefully, find the appendices useful. In particular, the section on estimators and uncertainties is of practical value and fundamental importance to the technique discussed here. ····· 10361132017

Correlations, Stabilities and Black Holes in String Theory and M-Theory

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
The present research offers thermodynamic geometric properties of black holes in string theory and M-theory. It systematically investigates the state-space and conformally related chemical geometries for extremal and non-extremal black holes, black strings, black rings and supertubes in four and higher spacetime dimensions. From the perspective of the intrinsic differential geometry, the questions of stability, regularity, existence of critical phenomena and phase transitions have been analyzed for charged anticharged black holes in a given basin of attractor. For the two parameter half BPS giants and superstars, an ensemble of arbitrary liquid droplets or irregular shaped fuzzballs shows that the chemical correlations involve ordinary summations, while the state-space correlations are depicted by standard polygamma functions. The state-space geometry provides definite stability character to black brane configurations under both the Planck length corrections and higher derivative stringy corrections. Perspective research includes D-branes, attractor mechanism, topological trees, Calabi-Yau compactifications, moduli space geometry and algebraic geometry. ····· 10361119344

Transverse Momentum Physics in hA and AA Interactions at High Energy

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
It is believed that the matter and radiation in the Universe were formed some fifteen billion years ago after a huge bang, called Big Bang. A fireball was created in this big bang. Now challenge is that how the fireball changed to the Universe we live in today. As laws of physics are improving day by day, we are becoming able to look further back in time, and to get knowledge about the evolution of this Universe. It is believed that matter and antimatter created in the big-bang were in equal amounts and also it is said that most of the antimatter was annihilated on matter during the formation of the Universe. This antimatter annihilation started when most of the matter we see in the Universe today was already in the form of hadrons made of quarks. But before this hadronized Universe, it had passed through a phase of quarks and gluons in free states. Physics of Quark Gluon Plasma QGP is the field in which physicists are trying to recreate this phase, and to study it in the laboratory. ····· 10361118434

Nuclear Fuel Rod Cracking

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Iodine induced stress corrosion cracking (I-SCC) in nuclear fuel rod sheathing is problematic for all nuclear reactors. The new Advanced CANDU Reactor (ACR) is discussed as a reactor design requiring related mitigation measures owing to a higher burn up and its unique refuelling scheme. A consequential release of iodine by the fuel pellets leads to stress corrosion induced failures and in extreme conditions can result in the release of radioactive contaminates into the atmosphere. This phenomenon is best exemplified by the disaster at the Fukushima Daiichi Nuclear Plant in Japan, March 2011, where melted fuel rods burnt holes in the containment vessels causing the release of radioactive iodine over land and the Pacific Ocean. This book develops a mechanistic kinetic model of the chemistry and thermodynamics in the fuel-to-sheath gap. The study also proposes remedies for I-SCC and suggests possible experimentation. The research in this book has been referenced in journal articles and conference proceedings. This book will be particularly useful as a reference source for professionals in the nuclear industry and others studying thermodynamics and kinetics. ····· 10361118330

Arsenic Contamination of Boreholes in the western region of Ghana

Surveillance of drinking water is a necessary action intended to prevent the general public from contaminating water borne diseases. In this study, arsenic concentrations in 22 borehole water samples from various locations in the Wassa West district have been studied using Instrumental Neutron Activation Analysis. The samples were irradiated using a 30 kW tank-in-pool Ghana Research Reactor-1 operating at a thermal neutron flux of 5 × 10 n s 1 cm-2. Elevated levels of arsenic were found in virtually all the 22 samples. Arsenic concentration in the samples ranged from 0.06 ppm to 9.43 ppm. (Mean-2.23, Standard Error of Mean-0.57) These values far exceed the World Health Organization s recommended value of 0.01 ppm for arsenic in drinking water. The occurrence of arsenic in the area is traced to the existence of sulphide minerals such as arsenopyrites (FeAsS2) present in the underlying Birimian Basement rocks in the area. ····· 10361117967

Overall Uncertainty Analysis

für 57.60€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
A study to perform an uncertainty analysis of the European accident consequence assessment system, Cosyma, has been carried out under contract to the European Commission. The study involved a series of analysis of the uncertainty in different sections of the system, followed by a final analysis of the uncertainty in the whole system. The overall aims of the study can be summarised as: - to formulate a state-of-the-art expert judgment methodology which is capable of finding broad acceptance - to apply the methodology to estimate uncertainties associated with the predictions of the probabilistic accident consequence system, Cosyma - to provide an input to identifying future research and development priorities. Uncertainties analysis involves specifying probability distributions for the values of each of the parameters involved, sampling sets of values from those distributions and propagating them through the model to derive information on the uncertainty in the model prediction. Those parameters whose uncertainties make major contributions to the overall uncertainty can then be identified using correlation coefficients between the input values and the model outputs. ····· 10361117731
