This book presents the select proceedings of the Virtual Conference on Disaster Risk Reduction (VCDRR 2021). It emphasizes on the role of civil engineering for a disaster-resilient society. It presents latest research in geohazards and their mitigation. Various topics covered in this book are earthquake hazard, seismic response of structures and earthquake risk. This book is a comprehensive volume on disaster risk reduction (DRR) and its management for a sustainable built environment. This book will be useful for the students, researchers, policy makers and professionals working in the area of civil engineering and earthquake engineering.

This book gathers selected high-quality research papers presented at the Sixth International Congress on Information and Communication Technology, held at Brunel University, London, on February 25–26, 2021. It discusses emerging topics pertaining to information and communication technology (ICT) for managerial applications, e-governance, e-agriculture, e-education and computing technologies, the Internet of things (IoT) and e-mining. Written by respected experts and researchers working on ICT, the book offers a valuable asset for young researchers involved in advanced studies. The book is presented in four volumes.

This book presents the first detailed study of one of the most important masterpieces of Renaissance cartography, Martin Waldseemüller’s Carta marina of 1516. By transcribing, translating into English, and detailing the sources of all of the descriptive texts on the map, as well as the sources of many of the images, the book makes the map available to scholars in a wholly unprecedented way.

This book describes the photocatalytic mechanism, factors affecting photocatalytic activity, design and preparation of different kinds of nanostructured photocatalysts, and their applications in the environmental and energy fields. Further, it illustrates a broad range of modification methods including ion-doping, heterojunction, noble metal deposition, morphological control and sensitizations, which are used to extend the light absorption range of photocatalysts and reduce recombination between electrons and holes. Promising applications include water splitting, contaminant decomposition and photocatalytic reduction of CO2, which are closely related to environmental redemption and new energy development. The book offers an intriguing and useful guide for a broad readership in various fields of catalysis, material sciences, environment and energy.

This sixth volume describes 226 species of 32 families of medicinal plants, which are commonly used in Chinese medicine. The most important species are Aquilaria sinensis and Daphne genkwa of Thymelaeaceae; Benincasa hispida, Siraitia grosvenorii, Trichosanthes kirilowii and Trichosanthes rosthornii of Cucurbitaceae; Camellia sinensis of Theaceae; Cleistocalyx operculatus, Eugenia caryophyllata and Rhodomyrtus tomentosa of Myrtaceae; Osbeckia chinensis of Melastomataceae; Quisqualis indica and Terminalia chebula of Combretaceae; Hypericum japonicum of Hypericaceae; Microcos paniculata of Tiliaceae; Hibiscus mutabilis of Malvaceae; Croton crassifolius, C. lachnocarpus, C. tiglium, Euphorbia humifusa, E. lathyris, E. pekinensis, Phyllanthus emblica and Sauropus spatulifolius of Euphorbiaceae.

This atlas covers all aspects of retina, retinal pigment epithelium, and choroidal tumors, as well as other simulating lesions of intraocular tumors and paraneoplastic syndromes. Each chapter features numerous high-quality pictures based on multimodal imaging, including color fundus photography, fundus autofluorescence, optical coherence tomography, ultrasonography, ultra-widefield imaging, and fundus angiography.
Designed to assist in the diagnosis and treatment of posterior segment intraocular tumors and simulating lesions, this book is intended for ocular oncologists, retina specialists, general ophthalmologists, residents and retina fellows.

This first of two fully updated volumes provides an in-depth account of breast disease characteristics, imaging and diagnosis. Covering from breast anatomy and tumor biology to benign and malignant lesions this is an indispensable companion for breast specialists, medical oncologists, radiologists and pathologists. The new edition contains chapters covering nuclear medicine and a chapter explaining biostatistical and epidemiological terms and has been updated to reflect the latest changes in biomarkers and cancer staging. The book explores topics such as epidemiology, risk factors, pathological evaluation of tumors and biopsy techniques.

The central theme of the present book is zigzags and central-circuits of three- or four-regular plane graphs, which allow a double covering or covering of the edgeset to be obtained. The book presents zigzag and central circuit structures of geometric fullerenes and several other classes of graph of interest in the fields of chemistry and mathematics. It also discusses the symmetries, parameterization and the Goldberg–Coxeter construction for those graphs.

Magic labelings Magic squares are among the more popular mathematical recreations. Their origins are lost in antiquity; over the years, a number of generalizations have been proposed. In the early 1960s, Sedlacek asked whether "magic" ideas could be applied to graphs. Shortly afterward, Kotzig and Rosa formulated the study of graph label­ ings, or valuations as they were first called. A labeling is a mapping whose domain is some set of graph elements - the set of vertices, for example, or the set of all vertices and edges - whose range was a set of positive integers. Various restrictions can be placed on the mapping. The case that we shall find most interesting is where the domain is the set of all vertices and edges of the graph, and the range consists of positive integers from 1 up to the number of vertices and edges. No repetitions are allowed. In particular, one can ask whether the set of labels associated with any edge - the label on the edge itself, and those on its endpoints - always add up to the same sum. Kotzig and Rosa called such a labeling, and the graph possessing it, magic. To avoid confusion with the ideas of Sedlacek and the many possible variations, we would call it an edge-magic total labeling.
