Outside back cover : "This book covers recent substantial improvements in diagnosis and treatment of anterior skull base tumors. This has been fostered by the introduction and rapid expansion of transnasal endoscopic techniques, in parallel with extraordinary progress made in all the other disciplines (pathology, radiology, neurosurgery, radiation oncology, medical oncology) which are involved in the complex process of managing these tumors. Chapters address nuances of treatment in relation to histology, as well as present views on selection criteria for surgical techniques"

This book is a comprehensive guide to skull base imaging. Skull base is often a “no man’s land” that requires treatment using a team approach between neurosurgeons, head and neck surgeons, vascular interventionalists, radiotherapists, chemotherapists, and other professionals. Imaging of the skull base can be challenging because of its intricate anatomy and the broad breadth of presenting pathology. Although considerably complex, the anatomy is comparatively constant, while presenting pathologic entities may be encountered at myriad stages. Many of the pathologic processes that involve the skull base are rare, causing the average clinician to require help with their diagnosis and treatment. But, before any treatment can begin, these patients must come to imaging and receive the best test to establish the correct diagnosis and make important decisions regarding management and treatment. This book provides a guide to neuoradiologists performing that imaging and as a reference for related physicians and surgeons. The book is divided into nine sections: Pituitary Region, Cerebellopontine Angle, Anterior Cranial Fossa, Middle Cranial Fossa, Craniovertebral Junction, Posterior Cranial Fossa, Inflammatory, Sarcomas, and Anatomy. Within each section, either common findings in those skull areas or different types of sarcomas or inflammatory conditions and their imaging are detailed. The anatomy section gives examples of normal anatomy from which to compare findings against. All current imaging techniques are covered, including: CT, MRI, US, angiography, CT cisternography, nuclear medicine and plain film radiography. Each chapter additionally includes key points, classic clues, incidence, differential diagnosis, recommended treatment, and prognosis. Skull Base Imaging provides a clear and concise reference for all physicians who encounter patients with these complex and relatively rare maladies. .

The South African Taxonomic soil classification system (SAT) is well established and utilised in South Africa. However, it is not internationally well known and therefore the need arose to provide a tool by which South African soil taxonomists can convert South African soil classifications and profile descriptions to the international classifications of the World Reference Base (WRB) for soil resources. The diagnostics and tacit knowledge presented in this publication are therefore based on the SAT and the WRB. When necessary, further substantiation was derived from the Land Type Survey of South Africa. The adopted procedure is effective in providing a reasonable classification based on the South African soil forms and families, while excluding certain WRB soil groups and qualifiers, because these are irrelevant to South African taxonomy. Lastly, this publication also highlights some peculiarities, omissions and inconsistencies observed between the SAT and WRB.

The OECD/G20 Base Erosion and Profit Shifting (BEPS) Project laid the foundations of the project to address the tax challenges arising from the digitalisation of the economy with the release of the BEPS Action 1 Report. Since then, the OECD/G20 Inclusive Framework on BEPS has been working on the issue, delivering an interim report in March 2018, at the request of the G20. In May 2019, the Inclusive Framework adopted a Programme of Work, which was endorsed by the G20 Finance Ministers and G20 Leaders in June 2019. The Programme of Work outlined proposals in two pillars that could form the basis for a multilateral consensus-based solution. It also provided that the OECD Secretariat would undertake an economic impact assessment of the proposals to ensure that all members of the Inclusive Framework could be kept fully informed of the economic and tax revenue impact of key decisions relating to the proposals. This report presents an ex ante analysis of the economic and tax revenue implications of the Pillar One and Pillar Two proposals under discussion by the Inclusive Framework as part of its work to address the tax challenges arising from the digitalisation of the economy.
