In this volume, practical questions that confront every history teacher are addressed using the latest research on cognition, teaching, and learning.

Provides a survey of the "Lattice Boltzmann equation" (LBE) theory and its major applications. Suitable for scientists dealing with complex system dynamics, this book also portrays future developments in allied areas of science, such as material science, biology and others, where fluid motion plays a distinguished role.

Exploring and Engaging Spirituality for Today's Children: A Holistic Approach answers questions about the most effective ways to help children, pre-teens, and teens develop spiritually. This collection of research gleaned from presentations during the Fourth Triennial Children's Spirituality Conference at Concordia University in 2012 is divided into four major sections: (1) theological and historical foundations, (2) engaging parents and congregations, (3) engaging methodologies, and (4) exploring children at risk, child pornography, social justice, intercultural diversity, and abstinence education. Researchers acknowledge that the home is the foundation for Christian nurture. In Exploring and Engaging Spirituality for Today's Children, both scholars and ministry leaders come together with parents to promote a holistic environment where children are encouraged to love, respect, and obey God. From birth to high school, children's voices resonate throughout these studies as they are invited to share their reflections and experiences. Exploring and Engaging Spirituality for Today's Children is a lively, easy-to-read collection that reflects a broad range of faith traditions and is ideal for all those who are committed to the spiritual development of children.

As the worldwide demands for basic minerals increase and some resources on land show signs of rapid decrease, it is inevitable that the search for new sources will extend to the oceans - the largely unexplored 71 percent of the planet's surface. Of great importance is the rich reserve of hard minerals in the oceans - for example the so-called manganese nodules, which vary in size and shape from small pebbles to massive pavements, containing economically attractive deposits of manganese, copper, cobalt, and nickel. It is important to assess the nature and extent of the mineral resources of the seabed and to devise ways of recovering them with a minimal impact on the environment. This report (based on an 18-month study) of a panel of the National Academy of Sciences examines the potential of the resources, evaluates the state of the art of ocean mining, identifies the legal, regulatory, and jurisdictional problems involved, considers the possible environmental questions, and determines how to meet the need for trained engineers to do the job.

This reprint of the 1985 architectural classic discusses a technology that offers an important alternative to conventional construction, having unique properties that make it useful for certain applications. Due to improvements in materials, structural analysis, and environmental control, these structures can often be considered permanent buildings. The membrane is the principal structural component of a tensioned fabric structure. Under certain circumstances, a tensioned fabric structure can reduce energy consumption in a building. The natural light from the translucent surface reduces requirements for artificial lighting, the reflectivity of the skin reduces heat gain, and the radiation of waste heat from the warm fabric surface to cool sky results in an energy-efficient building in warm climates. In cold climates, a second skin or liner is often used, often with glass fiber insulation in the cavity to further reduce heat loss. In general, as permanent structures, tensioned fabric technology is underutilized. There are many projects or parts of projects that could employ this system.
