Free Download Marko Miliša, "Plitvice Lakes " English | ISBN: 3031203771 | 2023 | 380 pages | EPUB | 241 MB After providing a historical overview, this book highlights the current state of knowledge, gaps in our knowledge, recent findings and future prospects with regard to the biological, chemical, geological, and geographical specificities of the Plitvice lakes in Croatia. The Plitvice lakes are a unique environment and home to tufa - a type of calcium carbonate deposit that provides a substrate for living organisms. Its formation process has resulted in a vastly diverse environment of lakes, streams and riparian habitats. The Plitvice lakes have, therefore, historically been both an inspiration and a challenge for scientists, nature enthusiasts, artists, etc. Today, the lakes continue to offer an in-situ laboratory for new discoveries in all aspects of freshwater science.  Free Download Azra Moeed, "Playful Science Investigations in Early Childhood: A Longitudinal Case Study " English | ISBN: 981997285X | 2024 | 116 pages | EPUB | 12 MB This book showcases a case study of the development of a generalist early childhood education (ECE) teacher into a confident and competent teacher of science in early childhood with support from a mentor. It argues that with guided mentoring, and later, timely support of a mentor as and when required, ECE teachers can deliver the curriculum, teach science by providing opportunities to explore and then build on children's interest through intentionally planned activities, dialogue, and discourse.  Free Download Sue Dale Tunnicliffe, "Play and STEM Education in the Early Years: International Policies and Practices" English | ISBN: 3030998290 | 2022 | 502 pages | EPUB | 55 MB This edited book provides an overview of unstructured and structured play scenarios crucial to developing young children's awareness, interest, and ability to learn Science, Technology, Engineering and Mathematics (STEM) in informal and formal education environments. The key elements for developing future STEM capital, enabling children to use their intuitive critical thinking and problem-solving abilities, and promoting active citizenship and a scientifically literate workforce, begins in the early years as children learn through play, employing trial and error, and often investigating on their own.  Free Download Robert Nzengwa, "Plate and Shell Models: Variational Methods in Plate and Shell Theory" English | ISBN: 9819727790 | 2025 | 309 pages | EPUB | 35 MB This book presents, in a variational form, very many two dimensional models which have been developed to overcome some weaknesses of the Kirchhoff-Love and Reissner-Mindlin's models. More precisely the N-T and N models are particularly treated because they clearly show the impact of the change in the third fundamental form whose contribution to the strain energy becomes important when the characteristic ratio of the shell is roughly greater than 0.3. Transverse stresses through-the-thickness are calculated. Gradient Recovery and Strain deformation approach with Curve triangular and Shifted Lagrange elements are implemented. These new FEM appear to be memory less greedy.  Free Download Wolfgang Frisch, "Plate Tectonics: Continental Drift and Mountain Building " English | ISBN: 303088998X | 2022 | 255 pages | EPUB | 229 MB This textbook explains how mountains are formed and why there are old and young mountains. It provides a reconstruction of the Earths paleogeography and shows why the shapes of South America and Africa fit so well together. Furthermore, it explains why the Pacific is surrounded by a ring of volcanos and earthquake-prone areas while the edges of the Atlantic are relatively peaceful.  Free Download Eric Maréchal, "Plastids: Methods and Protocols " English | ISBN: 1071637282 | 2025 | 333 pages | EPUB | 39 MB This second edition volume expands on the previous edition with new and updated chapters that explore our current view on plastid evolution, structure, and function. The chapters in this book are organized into three parts and cover topics such as plastid evolution, plasticity, and functional and structural diversity; techniques used to visualize, fractionate, purify, and study primary plastids from plant materials, and secondary plastids; and methods to analyze plastids by integrated biology strategies based on genetics, genomics, proteomics, and lipidomics. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.  Free Download Ololade Olatunji, "Plastic and Polymer Industry by Region: Production, Consumption and Waste Management in the African Continent" English | ISBN: 9811952302 | 2022 | 224 pages | EPUB | 65 MB This book addresses the need for a technical guided thought on production, consumption, and waste management of plastic and polymers in the African continent. Issues such as resource availability, processing technologies, plastic policies, and much more are covered in the book. While Africa is made up of several different countries which might be different from each other in many ways, these countries within the African continent have some commonalities such as region, some shared history, resources, and some shared policies through organizations such as the African Union, African Free trade Zone, and ECOWAS. With a population of over a billion, the African continent has become an attractive market for various businesses. Several publications in recent years have pushed for the advancement of the African continent toward increased manufacturing as a road to development. This inevitably includes the plastics and other polymers industry. Careful consideration must be taken to ensure thatthis growth will focus on more sustainable and greener manufacturing; otherwise, this anticipated growth in the plastics and polymer industry will only spell increased pollution and worsening of the environment.  Free Download Peng Yu, "Plasmon-enhanced light-matter interactions " English | ISBN: 3030875431 | 2022 | 355 pages | EPUB | 69 MB This book highlights cutting-edge research in surface plasmons, discussing the different types and providing a comprehensive overview of their applications. Surface plasmons (SPs) receive special attention in nanoscience and nanotechnology due to their unique optical, electrical, magnetic, and catalytic properties when operating at the nanoscale. The excitation of SPs in metal nanostructures enables the manipulation of light beyond the diffraction limit, which can be utilized for enhancing and tailoring light-matter interactions and developing ultra-compact high-performance nanophotonic devices for various applications. With clear and understandable illustrations, tables, and descriptions, this book provides physicists, materials scientists, chemists, engineers, and their students with a fundamental understanding of surface plasmons and device applications as a basis for future developments.
