This book presents a detailed review of the mineral deposits and occurrences in the Arabian-Nubian Shield (ANS), including their distribution, mineralization styles, economic importance, and geological controls on the mineralization. The purpose of the book is to compile the results of past and recent investigations on mineral deposits and occurrences in the ANS that covering the countries of (Saudi Arabia, Yemen, Egypt, Sudan, Eritrea, and Ethiopia). In this regard, it discusses in detail the various genetic mineralization styles in the ANS including: (1) magmatic mineral deposits associated with mafic-ultramafic rocks (e.g. chromite, Ni-Cu-Co-PGE magmatic sulfides, Fe-Ti-V oxides), (2) intrusion-related (magmatic-hydrothermal) deposits associated with felsic to intermediate rocks (porphyry, epithermal Au-Ag/sulfide vein type family, skarn, granite-related pegmatite-REE deposits), (3) hydrothermal orogenic gold and volcanogenic massive sulfide (VMS) deposits, as well as (4) surficial mineral deposits (chemical-sedimentary, residual, mechanical and supergene enrichment deposits).

This book empirically explores assessment of EFL (English as a Foreign Language) writing in different Arab world contexts at the university level, which often presents a challenge for teachers and students alike. Analysing a number of different practices throughout the chapters including peer assessment, self-assessment, e-rubrics and writing coherence, the authors highlight different issues and challenges that affect the assessment of EFL writing in the Arab world, and provide valuable insights into how it can be improved. This book is sure to become an important practical resource for practitioners, researchers, professors and graduate students working on EFL writing in this region.

Teaching EFL Writing in the 21st Century Arab World addresses a range of issues related to researching and teaching EFL writing in different countries in the Arab World including Egypt, Morocco, Oman, Palestine, Tunisia, UAE and Yemen. Both theoretically and practically grounded, chapters within discuss the different contexts in which EFL writing is taught, from primary school to university. The book sheds light on how EFL writing is learned and taught at each educational stage, exposing the different challenges encountered in the teaching and learning. The focus on EFL writing in the Arab World makes this a unique and long overdue contribution to the field of research around EFL writing and will be an invaluable resource for researchers, curriculum designers and students.

This volume constitutes short papers and DETECT 2022 workshop papers, presented during the 11th International Conference on Model and Data Engineering, MEDI 2022, held in Cairo, Egypt, in November 2022. The 11 short papers presented were selected from the total of 65 submissions. This volume also contains the 4 accepted papers from the DETECT 2022 workshop, held at MEDI 2022. The volume focuses on advances in data management and modelling, including topics such as data models, data processing, database theory, database systems technology, and advanced database applications.
