The Seismic Analysis Code

A Primer and User's Guide

By: George Helffrich,James Wookey,Ian Bastow

The Seismic Analysis Code (SAC) is one of the most widely used analysis packages for regional and teleseismic seismic data. For the first time, this book provides users at introductory and advanced levels with a complete guide to SAC. It leads new users of SAC through the steps of learning basic commands, describes the SAC processing philosophy, and presents its macro language in full, supported throughout with example inputs and outputs from SAC. For more experienced practitioners, the book describes SAC's many hidden features, including advanced graphics aspects, its file structure, how to write independent programs to access and create files, and much more. Tutorial exercises engage users with newly acquired skills, providing data and code to implement the standard methods of teleseismic shear-wave splitting and receiver function analysis. Methodical and authoritative, this is a key resource for researchers and graduate students in global seismology, earthquake seismology and geophysics.

Green Adsorbents

By: George Z. Kyzas

Adsorption technology is a promising avenue for wastewater treatment. Numerous adsorbent materials are presently synthesized. Green or environmental friendly adsorbents are derived from plants and agricultural crop sources, giving them a very low production cost when compared to synthetic polymers. This monograph explains the basic principles of green adsorption technology, their production processes and strategies to remove different categories of environmental pollutants (dyes, heavy metals and phenols/pesticides). The book explains details in terms of features such as adsorption capacity, physico-chemical kinetics and reuse potential. A summary of the economics and future prospect for green adsorption technology is also given. This text is a handy reference for environmental chemistry students, researchers and policy makers.

An Hour with George Muller

The Man of Faith to Whom God Gave Millions

By: George Muller

The eccentric pastor and orphan-lover George Muller cared for at least 10, 000 orphans in his lifetime and after his death through his legacy of inspiring others to do the same, the number of children increased to 100,000. He prayed in millions of dollars (in today's currency the estimate is 150 million) for the orphans and never asked anyone directly for money. He never took a salary in the last 68 years of his ministry, but trusted God to put in people's hearts to send him what he needed. And neither he nor the orphans were ever hungry or lacking in any necessities.

George MacDonald and the Late Great Hell Debate

By: Michael Phillips,George MacDonald

The leading MacDonald scholar settles the longstanding debate about the author’s views on hell with an in-depth analysis of his thought on the afterlife. Throughout his extensive and influential writings on Christian theology, George MacDonald only hints at his perspectives on hell, atonement, and everlasting punishment. Nowhere does he clearly state a doctrinal position on the subject. As a result, a controversy has raged for more than a century about whether or not MacDonald was a universalist. Now MacDonald scholar and biographer Michael Phillips tackles the “great hell debate” head on in this authoritative book. With numerous quotes from MacDonald’s writings and his extensive knowledge of MacDonald’s work, Phillips blows the lid off the debate by illuminating the full scope of MacDonald’s afterlife vision. One of the most significant studies of MacDonald’s theological perspectives ever written, this is a must-read for all serious students of George MacDonald.
