This book includes recent articles with new findings in Mathematics and Computer Science, Microbiology and Biotechnology, Environmental Science and Oceanography, Physics and Physical Chemistry, Chemistry, and Biochemistry. Also, it contains some articles on the state of the art. The books shows the interaction of the different disciplines of basic sciences and their roles to achieve the green environment and sustainable development via the application of green sciences. Also, the data and information in this book include solving problems in the statistic statistical and computer analysis of many experimental data; broaden the understanding for of many environmental phenomena; broaden the understanding on of how many green synthetic materials could be achieved and examples of their application in biochemistry and microbiology fields; explain how the basic sciences can help in the sustainable development; and explain how deep learning could be used in predicting some phenomena. Additionally, the book enriches understanding of many microbiological and biochemical phenomena and provides complete instructions for many biotechnological aspects. It provides complete instructions for representative waste treatment; enriches understanding of how some biochemical compounds could be tested for representative disease management; case studies that illustrate newly developed equation equations in physics; and summarizes the latest studies in the completeness between basic sciences and climate changes.
