Decades of research have demonstrated that the parent-child dyad and the environment of the familyâ€"which includes all primary caregiversâ€"are at the foundation of children's well- being and healthy development. From birth, children are learning and rely on parents and the other caregivers in their lives to protect and care for them. The impact of parents may never be greater than during the earliest years of life, when a child's brain is rapidly developing and when nearly all of her or his experiences are created and shaped by parents and the family environment. Parents help children build and refine their knowledge and skills, charting a trajectory for their health and well-being d...
Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thru...

This book of ICSDWE2022 aims to advance the understanding of both the fundamentals of related fields in sustainable development of water and environment and its application to the solution of challenges and problems in engineering. The committee of ICSDWE2022 gathers scholars and experts in related fields both at home and abroad. Under the guidance of the committee, we are confident to the publication of high-quality papers on all aspects of water and environment. The book features graduate-level texts and professional books in related fields. We hope that most scholars, researchers, and engineers can find what they really need in our book.
