Скачать книгу - Dawn-Dusk Asymmetries in Planetary Plasma Environments
Dawn­Dusk Asymmetries in Planetary Plasma Environments Dawn-dusk asymmetries are ubiquitous features of the plasma environment of many of the planets in our solar system. They occur when a particular process or feature is more pronounced at one side of a planet than the other. For example, recent observations indicate that Earth's magnetopause is thicker at dawn than at dusk. Likewise, auroral breakups at Earth are more likely to occur in the pre-midnight than post-midnight sectors. Increasing availability of remotely sensed and in situ measurements of planetary ionospheres, magnetospheres and their interfaces to the solar wind have revealed significant and persistent dawn-dusk asymmetries. As yet there is no consensus regarding the source of many of these asymmetries, nor the physical mechanisms by which they are produced and maintained. Volume highlights include: A comprehensive and updated overview of current knowledge about dawn-dusk asymmetries in the plasma environments of planets in our solar system and the mechanisms behind them Valuable contributions from internationally recognized experts, covering both observations, simulations and theories discussing all important aspects of dawn-dusk asymmetries Space weather effects are caused by processes in space, mainly the magnetotail, and can be highly localized on ground. Knowing where the source, i.e., where dawn-dusk location is will allow for a better prediction of where the effects on ground will be most pronounced Covering both observational and theoretical aspects of dawn dusk asymmetries, Dawn­-Dusk Asymmetries in Planetary Plasma Environments will be a valuable resource for academic researchers in space physics, planetary science, astrophysics, physics, geophysics and earth science.


From the Campfire to the Holodeck. Creating Engaging and Powerful 21st Century Learning Environments From the Campfire to the Holodeck. Creating Engaging and Powerful 21st Century Learning Environments

Автор: David Thornburg

Год издания: 

How to optimize educational spaces and teaching practices for more effective learning Author David Thornburg, an award-winning futurist and educational consultant, maintains that in order to engage all students, learning institutions should offer a balance of Campfire spaces (home of the lecture), Watering Holes (home to conversations between peers), Caves (places for quiet reflection), and Life (places where students can apply what they've learned). In order to effectively use technology in the classroom, prepare students for future careers, and incorporate project-based learning, all teachers should be moving from acting as the «sage on the stage» to becoming the «guide on the side.» Whether you are a school administrator interested in redesigning your school or a teacher who wants to prepare better lessons, From the Campfire to the Holodeck can help by providing insight on how to: Boost student engagement Enable project-based learning Incorporate technology into the classroom Encourage student-led learning From the Campfire to the Holodeck is designed to help schools move from traditional lecture halls (Campfires) where students just receive information to schools that encourage immersive student-centered learning experiences (Holodecks).

Fundamentals of Ionized Gases. Basic Topics in Plasma Physics Fundamentals of Ionized Gases. Basic Topics in Plasma Physics

Автор: Boris Smirnov M.

Год издания: 

A comprehensive and readily accessible work for studying the physics of ionized gases, based on «Physics of Ionized Gases». The focus remains on fundamentals rather than on the details required for interesting but difficult applications, such as magnetic confinement fusion, or the phenomena that occur with extremely high-intensity short-pulse lasers. However, this new work benefits from much rearranging of the subject matter within each topic, resulting in a more coherent structure. There are also some significant additions, many of which relate to clusters, while other enlarged sections include plasmas in the atmosphere and their applications. In each case, the emphasis is on a clear and unified understanding of the basic physics that underlies all plasma phenomena. Thus, there are chapters on plasma behavior from the viewpoint of atomic and molecular physics, as well as on the macroscopic phenomena involved in physical kinetics of plasmas and the transport of radiation and of charged particles within plasmas. With this grounding in the fundamental physics of plasmas, the notoriously difficult subjects of nonlinear phenomena and of instabilities in plasmas can then be treated with comprehensive clarity. The work is rounded off with appendices containing information and data of great importance and relevance that are not easily found in other books. Valuable reading for graduate and PhD physics students, and a reference for researchers in low-temperature ionized gases-plasma processing, edge region fusion plasma physics, and atmospheric plasmas.
