    Abstract: This book covers topics related to viral and fungal infections of the central nervous system (CNS), with a multidisciplinary reach, discussing associated immunology, microbiological aspects, pathologies, timely management, and prevention. The book is structured into five broad sections. The first section provides the reader with valuable insights into the aetiologies and underlying pathophysiological mechanisms of neurological diseases, including host responses. It mentions all bacterial, fungal, parasitic, and viral causes of neuro-infections, along with rarer neuropathogenesis such as prions and mycoplasmas. The chapter also presents detailed epidemiology and prevalence of different CNS infections worldwide. It also reviews various infectious diseases that target the nervous system, such as focal lesions, meningitis, and neurological complications of venous sinus thrombosis. The next two sections delve deep into pathogen-specific diseases of the CNS, namely the viruses and fungi associated with neuro-infections. It mentions detailed excerpts on encephalitic viruses, long-term consequences of neurotropic viruses, mycological neuroinfectious, and even the emerging, less talked of viruses and fungi causing neurological disease. Topics such as principles of vigorous antifungal therapy and surgeries are also discussed in the chapter. The fourth section gives an insight on prospects for efficiently diagnosing and managing viral and fungal CNS infections, to tackle associated morbidities. Features that are often less documented, yet of considerable interest in current times, such as the role of immunosuppression in neurological infections and newer microbiological diagnostic strategies are covered. The last section uniquely provides clinicians with relatable case scenarios. Real case descriptions are included, such as cases of fungal meningitis and other difficult-to-diagnose infections produced by viruses. This book serves as a guide for neurologists, medical microbiologists, and clinical practitioners who deal with patients suspected of neurological infection.

    Abstract: This book includes over three hundred and seventy-five short papers presented during the second EMCEI, which was held in Sousse, Tunisia in October 2019. After the success of the first EMCEI in 2017, the second installment tackled emerging environmental issues together with new challenges, e.g. by focusing on innovative approaches that contribute to achieving a sustainable environment in the Mediterranean and surrounding regions and by highlighting to decision makers from related sectors the environmental considerations that should be integrated into their respective activities. Presenting a wide range of environmental topics and new findings relevant to a variety of problems in these regions, this volume will appeal to anyone working in the subject area and particularly to students interested in learning more about new advances in environmental research initiatives in view of the worsening environmental degradation of the Mediterranean and surrounding regions, which has made environmental and resource protection into an increasingly important issue hampering sustainable development and social welfare.

    Abstract: This book focuses on the evolution of sedimentary basins of the Arabian Plate and its surroundings. Because these sedimentary basins developed in various tectonic settings, from extensional or transtensional to flexural, transpressional or compressional, their sedimentary sequences provide unique records of the regional geology. Georesources of the Arabian Plate are also described here, including petroleum potential, reservoirs, water resources, fresh water and deep saline aquifers, as well as materials and ore deposits. The book is made by a set of papers authored by geoscientists working in both academia and industry. Numerous chapters describe some regional important geologic features and selected sedimentary basins from the Middle East, North Africa and the Arabian Peninsula domains. Other chapters focus on georesources. A particular focus is given to the geology of Saudi Arabia. This book is an important contribution to the geology of the Arabian Peninsula and its surroundings. In view of the strategic and economic importance of the regional geology and georesources of the Arabian Plate and Surroundings, this volume will constitute an important reference for a wide range of geoscientists interested in the geology of this region, especially those active in petroleum geosciences and related industry. Ultimately, readers will discover important thematic maps in this book.

    Abstract: This book summarizes the links between the evolution of sedimentary basins of Northern Africa and Peri-Mediterranean in different tectonic settings and the distribution of georesources in those basins. Georesources include fossil energy, geothermal energy, deep aquifers, minerals and deposits. This book also provides key information for energy resources in these important areas. The book is in part a compilation of selected papers from Atlas Georesources International Congress, Hammamet, Tunisia, (AGIC 2017) which were extended after the congress in addition to other contributions from geoscientists based at some universities and companies from the region. It is organized in a set of research studies focusing on the architecture, geodynamic evolution and modeling of sedimentary basins in the Middle East, North Africa and the Mediterranean domain. Future developments in the exploration for water, energy and other georesources are very important in these regions. In this context, this book constitutes an important reference for a wide range of geoscientists and companies as it defines the distribution and potentialities of these resources. .

    Reassessing evidence of Moon–Earth dynamics from tidal bundles at 3.2 Ga (Moodies Group, Barberton Greenstone Belt, South Africa) (2022)
    Details
    Publication Date: 2022-10-04
    Description: Past orbital parameters of the Moon are difficult to reconstruct from geological records because relevant data sets of tidal strata are scarce or incomplete. The sole Archean data point is from the Moodies Group (ca 3.22 Ga) of the Barberton Greenstone Belt, South Africa. From the time‐series analysis of tidal bundles from a well‐exposed subaqueous sand wave of this unit, Eriksson and Simpson (Geology, 28, 831) suggested that the Moon’s anomalistic month at 3.2 Ga was closer to 20 days than the present 27.5 days. This is in apparent accordance with models of orbital mechanics which place the Archean Moon in a closer orbit with a shorter period, resulting in stronger tidal action. Although this study’s detailed geological mapping and section measuring of the site confirmed that the sandstone bed in question is likely a migrating dune, the presence of angular mud clasts, channel‐margin slumps, laterally aggrading channel fills and bidirectional paleocurrents in overlying and underlying beds suggests that this bedform was likely located in a nearshore channel near lower‐intertidal flats and subtidal estuarine bars; it thus carries risk of incomplete preservation. Repeated measurements of foreset thicknesses along the published traverse, measured perpendicular to bedding, failed to show consistent spectral peaks. Larger data sets acquired along traverses measured parallel to bedding along the 20.5 m wide exposure are affected by minor faulting, uneven outcrop weathering, changing illumination, weather, observer bias and show a low reproducibility. The most robust measurements herein confirm the periodicity peak of approximately 14 in the original data of Eriksson and Simpson (Geology, 28, 831). Because laminae may have been eroded, the measurements may represent a lower bound of about 28 lunar days per synodic month. This estimate agrees well with Earth–Moon dynamic models which consider the conservation of angular momentum and place the Archaean Moon in a lower orbit around a faster‐spinning Earth.
