'Hill's advice is straightforward and no-nonsense' - The Guardian 'A life-transforming book... fascinating - Daily Mail 'Maisie Hill has written a bloody brilliant book (pun intended). Everything you need to know about periods and how they affect you and your life is here. It's revolutionary' - Miranda Sawyer 'Thank GOODNESS for Maisie Hill! Flipping open the lid on a vital conversation. It's about time we claimed the power of our periods!' - Gemma Cairney, broadcaster & co-founder of Boom Shakalaka Productions 'This is such an important book. Maisie's insights and cycle strategy have changed my life and my cycle. Period Power is written with such intelligence, humour and a deep understanding of women's health. If you have a period you need to read this book.' - Anna Jones, author of The Modern Cook's Year A profound and practical blueprint for aligning daily life with your menstrual cycle. Period Power is the handbook to periods and hormones that will leave you wondering why the hell nobody told you this sooner. The hormones of the menstrual cycle profoundly influence our energy, mood and behaviour, but all too often we're taught that our hormones make us unreliable, moody bitches, or that it's our lot in life to put up with 'women's problems'. Maisie Hill, a women's health practitioner, knows the power of working with the menstrual cycle and refuses to accept this theory. Instead, Maisie believes that our hormones are there to serve us and, if utilized correctly, can be used to help you get what you want out of life. Yes, we are hormonal, and that's a very good thing. This revolutionary book reveals everything you need to know about taking control of your menstrual cycle and outlines The Cycle Strategy to help us perform at our best, throughout our cycle. In Period Power you will discover how to: - maximise your natural superpowers each month while making adjustments for the darker days, and use Maisie's favourite tips to improve them - identify your personal patterns, powers and pitfalls for each phase of the menstrual cycle - plan your month to perform at your best in all aspects of your life - figure out if you have a hormonal imbalance and what to do about it. Period Power is a no-nonsense guide with all the tools you need to improve your menstrual health.

Systems, Cycles, Seasons, and Processes takes you on a journey to discover the laws, concepts, and principles that govern the seen and unseen realms of life. Emjay helps the reader identify the cues that unlock the mysteries that determine success or failure in a person's life. You'll never again ask why this or that happened, you'll know why and you'll know exactly what you need to do to change the outcome in any situation.

We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet presents prioritized science, applications, and observations, along with related strategic and programmatic guidance, to support the U.S. civil space Earth observation program over the coming decade.

A comprehensive guide to carbon inside Earth - its quantities, movements, forms, origins, changes over time and impact on planetary processes. This title is also available as Open Access on Cambridge Core.

The interactions of biogeochemical cycles influence and maintain our climate system. Land use and fossil fuel emissions are currently impacting the biogeochemical cycles of carbon, nitrogen and sulfur on land, in the atmosphere, and in the oceans.This edited volume brings together 27 scholarly contributions on the state of our knowledge of earth system interactions among the oceans, land, and atmosphere. A unique feature of this treatment is the focus on the paleoclimatic and paleobiotic context for investigating these complex interrelationships.* Eight-page colour insert to highlight the latest research* A unique feature of this treatment is the focus on the paleoclimatic context for investigating these complex interrelationships.

Ovarian Cycle, Volume 107, the latest in the Vitamins and Hormones series first published in 1943, and the longest-running serial published by Academic Press, covers the latest updates on hormone action, vitamin action, X-ray crystal structure, physiology and enzyme mechanisms. This latest release includes an overview of the ovarian cycle, a section on ovarian hyperstimulation syndrome, information on androgens and ovarian follicular maturation, information on peptide inhibitors of human thymidylate synthase to inhibit ovarian cancer cell growth, sections on nodal and luteolysis, neurokinins, dynorphin and pulsatile Lh secretion, Lh receptor expression by Mir12, and gonadotrophin-surge attenuating factor, melatonin and Bmp-6 regulation, amongst other topics. Focuses on the newest aspects of hormone action in connection with diseases Lays the groundwork for the focus of new chemotherapeutic targets Reviews emerging areas in hormone action, cellular regulators and signaling pathways

Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.

Over the last decade, the study of cycles as a model for the earth's changing climate has become a new science. Earth Systems Science is the basis for understanding all aspects of anthropogenic global change, such as chemically forced global climate change. The work is aimed at those students interested in the emerging scientific discipline.Earth Systems Science is an integrated discipline that has been rapidly developing over the last two decades. New information is included in this updated edition so that the text remains relevant. This volume contains five new chapters, but of special importance is the inclusion of an expanded set of student exercises.The two senior authors are leading scientists in their fields and have been awarded numerous prizes for their research efforts.* First edition was widely adopted* Authors are highly respected in their field* Global climate change, integral to the book, is now one of the most important issues in atmospheric sciences and oceanography
