Gaming and Geography: A Multi-perspective Approach to Understanding the Impacts on Geography (Education) (Key Challenges in Geography)
by Michael Morawski Sebastian Wolff-SeidelThis book explores the uncharted territory where gaming and geography intersect in "Gaming and Geography (Education)." This book bridges the gap between video games and geography, delving into the constructivist creative processes of game development, gameplay, and critical reflections on video games' role in geographical discourses. Through a multi-perspective lens, the book examines how video games can facilitate the exploration of geographic questions and act as catalysts for critical discourses. Scholars shed light on the geographies presented in video games, including their representations, spatial images, and policies. By viewing video games as cultural and critical geography practices, the authors enrich the political, socio-cultural, and critical geographies associated with this medium. A key argument of the book is that video games can foster systemic competence and networked thinking, particularly in addressing complex socio-ecological challenges like climate change and migration. In contrast to traditional geography classes, digital games provide valuable simulations of complex systems, enhancing students' understanding and skills. The book also explores other possibilities such as digital field trips and language support to enhance the educational experience. "Gaming and Geography (Education)" offers a compelling narrative that highlights the diverse roles video games can play in geographic education. By exploring the intersection of gaming and geography, this book deepens our understanding of this dynamic relationship and its impact on critical geographies within the realm of video games.
Gamma Cameras for Interventional and Intraoperative Imaging (Series in Medical Physics and Biomedical Engineering)
by Alan C. Perkins John E. LeesGamma cameras are traditionally large devices that are situated in nuclear medicine departments, but recent advances in detector design have enabled the production of compact gamma cameras that allow nuclear imaging at the patient bedside and in the operating theatre. Gamma Cameras for Interventional and Intraoperative Imaging is the first book to cover this new area of imaging, and provides a unique insight into the experimental and clinical use of small field of view gamma cameras in hospitals. This book explores advances in the design and operation of compact gamma cameras and conducts a thorough review of current SFOV systems, before exploring the clinical applications of the technology. It is an essential reference for surgeons, operating theatre staff, clinical scientists (medical physicists), technologists, nuclear physicians and radiologists whose patients could benefit from this technology.

Gamma Rays in the 100 TeV Region from Potential Galactic PeVatron Candidates: Observation with the Tibet Air Shower Array and the Muon Detector Array (Springer Theses)
by Sei KatoThis book presents two candidates for astrophysical accelerators of cosmic rays with petaelectron-volt (PeV) energies in our Galaxy, the so-called PeVatrons, through the observation of sub-PeV gamma rays performed by the Tibet air shower array. The two gamma-ray sources are TASG J1844-038—a newly detected source in this presented work—and HESS J1849-000. Reconstructing their gamma-ray energy spectra up to the sub-PeV range and also analyzing the archive data published by a radio survey, the book discusses in depth the emission mechanisms of the observed gamma rays and suggests that these two gamma-ray sources are candidates for PeVatrons. The results give insights into the population of PeVatron in the Galaxy, which is important to consider their contribution to the PeV cosmic rays observed at the Earth.
Gamma-Glutamyl Transpeptidases: Structure and Function
by Immacolata Castellano Antonello MerlinoGamma-Glutamyl Transpeptidases (γ-GTs) are members of the N-terminal nucleophile hydrolase superfamily, enzymes that cleave the γ-glutamyl amide bond of glutathione to liberate cysteinylglycine. The released γ-glutamyl group can be transferred to water (hydrolysis) or to amino acids or short peptides (transpeptidation). γ-GT plays a key role in the gamma glutamyl cycle by regulating the cellular levels of the antioxidant glutathione, hence it is a critical enzyme in maintaining cellular redox homeostasis.γ-GT is upregulated during inflammation and in several human tumors, and it is involved in many physiological disorders related to oxidative stress, such as Parkinson's disease and diabetes. Furthermore, this enzyme is used as a marker of liver disease and cancer. This book covers current knowledge about the structure-function relationship of γ-GTs and gives information about applications of γ-GTs in different fields ranging from clinical biochemistry to biotechnology and biomedicine.
Gamma-Hydroxybutyrate: Pharmacological and Functional Aspects
by Godfrey Tunnicliff Christopher D. CashGamma-hydroxybutyrate (GHB) has come a long way since early experiments in animals where it was found to induce a sleep-like state and from its use in general anaesthesia in human subjects. It has been found to be a naturally-occurring compound in the brain, a metabolite of GABA, the emerging ubiquitous inhibitory neurotransmitter. This has opened
Gamma-ray Bursts
by Chryssa Kouveliotou Ralph A. M. J. Wijers Stan WoosleyCosmic gamma ray bursts (GRBs) have fascinated scientists and the public alike since their discovery in the late 1960s. Their story is told here by some of the scientists who participated in their discovery and, after many decades of false starts, solved the problem of their origin. Fourteen chapters by active researchers in the field present a detailed history of the discovery, a comprehensive theoretical description of GRB central engine and emission models, a discussion of GRB host galaxies and a guide to how GRBs can be used as cosmological tools. Observations are grouped into three sets from the satellites CGRO, BeppoSAX and Swift, and followed by a discussion of multi-wavelength observations. This is the first edited volume on GRB astrophysics that presents a fully comprehensive review of the subject. Utilizing the latest research, Gamma Ray Bursts is an essential desktop companion for graduate students and researchers in astrophysics.
Gamma-ray and Neutrino Signatures of Galactic Cosmic-ray Accelerators (Springer Theses)
by Silvia CelliThis book addresses three “hot” topics concerning the general problem of the origin of Galactic cosmic rays, namely (1) the acceleration, propagation, and radiation of particles in supernova remnants; (2) very high energy neutrinos from the Galactic Center; and (3) the potential held by the next-generation gamma-ray and neutrino detectors CTA and KM3NeT for studying extended non-thermal sources in the Galaxy. The topics are intrinsically connected to determining the nature (“hadronic or leptonic?”) of gamma-ray emissions from young and middle-aged supernova remnants and the search for cosmic-ray PeVatrons. The results and conclusions provided here are based on extensive analytical and numerical simulations, which are formulated and presented in a straightforward format that can be readily used in the interpretations of gamma-ray and neutrino observations, as well as for confident predictions for future measurements.
Gamma: Exploring Euler's Constant (Princeton Science Library #53)
by Julian HavilAmong the many constants that appear in mathematics, π, e, and i are the most familiar. Following closely behind is y, or gamma, a constant that arises in many mathematical areas yet maintains a profound sense of mystery. In a tantalizing blend of history and mathematics, Julian Havil takes the reader on a journey through logarithms and the harmonic series, the two defining elements of gamma, toward the first account of gamma's place in mathematics. Introduced by the Swiss mathematician Leonhard Euler (1707-1783), who figures prominently in this book, gamma is defined as the limit of the sum of 1 + 1/2 + 1/3 + . . . Up to 1/n, minus the natural logarithm of n--the numerical value being 0.5772156. . . . But unlike its more celebrated colleagues π and e, the exact nature of gamma remains a mystery--we don't even know if gamma can be expressed as a fraction. Among the numerous topics that arise during this historical odyssey into fundamental mathematical ideas are the Prime Number Theorem and the most important open problem in mathematics today--the Riemann Hypothesis (though no proof of either is offered!). Sure to be popular with not only students and instructors but all math aficionados, Gamma takes us through countries, centuries, lives, and works, unfolding along the way the stories of some remarkable mathematics from some remarkable mathematicians.
Gamow Shell Model: The Unified Theory of Nuclear Structure and Reactions (Lecture Notes in Physics #983)
by Nicolas Michel Marek PłoszajczakThis book provides the first graduate-level, self-contained introduction to recent developments that lead to the formulation of the configuration-interaction approach for open quantum systems, the Gamow shell model, which provides a unitary description of quantum many-body system in different regimes of binding, and enables the unification in the description of nuclear structure and reactions. The Gamow shell model extends and generalizes the phenomenologically successful nuclear shell model to the domain of weakly-bound near-threshold states and resonances, offering a systematic tool to understand and categorize data on nuclear spectra, moments, collective excitations, particle and electromagnetic decays, clustering, elastic and inelastic scattering cross sections, and radiative capture cross sections of interest to astrophysics. The approach is of interest beyond nuclear physics and based on general properties of quasi-stationary solutions of the Schrödinger equation – so-called Gamow states. For the benefit of graduate students and newcomers to the field, the quantum-mechanical fundamentals are introduced in some detail. The text also provides a historical overview of how the field has evolved from the early days of the nuclear shell model to recent experimental developments, in both nuclear physics and related fields, supporting the unified description. The text contains many worked examples and several numerical codes are introduced to allow the reader to test different aspects of the continuum shell model discussed in the book.
Gandhi and the Psychology of Nonviolence, Volume 2: Applications across Psychological Science
by Rita Agrawal V. K. KoolIn volume 1 of Gandhi and the Psychology of Nonviolence the authors advanced a scientific psychology of nonviolence, derived from principles enunciated by Gandhi and supported by current state-of-the-art research in psychology. In this second volume the authors demonstrate its potential contribution across a wide range of applied psychology fields. As we enter the era of the Anthropocene, they argue, it is imperative to make use of Gandhi’s legacy through our evolving noospheric consciousness to address the urgent problems of the 21st century. The authors examine Gandhi’s contributions in the context of both established areas such as the psychology of religion, educational, community and organizational psychology and newer fields including environmental psychology and the psychology of technology. They provide a nuanced analysis which engages with both the latest research and the practical implications for initiatives like the Intergovernmental Panel on Climate Change and the UN’s Sustainable Development Goals.The book concludes with an overview of Gandhi’s contribution to modern psychology, which encompasses the history, development, and current impetus behind emerging work in the field as a whole. It marks an exciting contribution to studies of both Gandhi and psychology that will also provide unique insights for scholars of applied psychology, education, environmental and development studies.

Gangs, Pseudo-Militaries, and Other Modern Mercenaries: New Dynamics in Uncomfortable Wars (International and Security Affairs Series #6)
by Max G. Manwaring Edwin G. Corr John T. Fishel<p>As the first decade of the twenty-first century has made brutally clear, the very definitions of war and the enemy have changed almost beyond recognition. Threats to security are now as likely to come from armed propagandists, popular militias, or mercenary organizations as they are from conventional armies backed by nation-states. In this timely book, national security expert Max G. Manwaring explores a little-understood actor on the stage of irregular warfare—the gang. <p>Since the end of the Cold War, some one hundred insurgencies or irregular wars have erupted throughout the world. Gangs have figured prominently in more than half of those conflicts, yet these and other nonstate actors have received little focused attention from scholars or analysts. This book fills that void. <p>Employing a case study approach, and believing that shadows from the past often portend the future, Manwaring begins with a careful consideration of the writings of V. I. Lenin. He then scrutinizes the Piqueteros in Argentina, gangs in Colombia, private armies in Mexico, Hugo Chavez's use of popular militias in Venezuela, and the looming threat of Al Qaeda in Western Europe. <p>As conventional warfare is increasingly eclipsed by these irregular and “uncomfortable” wars, Manwaring boldly diagnoses the problem and recommends solutions that policymakers should heed.</p>
Ganoderma Diseases of Tropical Crops
by Paul Bridge Dr Carmel A PilottiThe fungal genus Ganoderma includes around 80 currently recognized species that are widely distributed in temperate, subtropical and tropical regions, and cause disease in a range of economically important perennial crops and tree-like plants. Ganoderma root and lower stem rots have a significant impact on yields from crops including oil palm, coconut, beverage crops, Acacia and rubber. The identification of species responsible for stem and butt rots is often ambiguous as closely related species may only be distinguished by subtle morphological differences. Within species there can be considerable morphological plasticity and this can make morphology-based identification difficult, particularly for species described from a single specimen. Molecular techniques are helping to slowly resolve Ganoderma taxonomy but it will be some time (if ever) before the taxonomy is fully resolved. This book brings together information on Ganoderma species that are reported to be responsible for crop diseases in tropical and sub-tropical agriculture and covers taxonomy, biology, genetics, aetiology, epidemiology and control. This book is an essential resource for researchers in Ganoderma in crop science and tropical agriculture, as well as practitioners and industry.
