This third volume of Concrete in the Service of Mankind focuses on appropriate concrete technology. Concrete is ubiquitous and unique, and is found in every developed and developing country. Indeed, there are no alternatives to concrete as a volume construction material for infrastructure. This raises important questions of how concrete should be designed and constructed for cost effective use in the the short and long term, and to encourage further radical development. Equally, it must be environmentally friendly during manufacture, in an aesthetic presentation in structures and in the containment of harmful materials. This book should be of interest to concrete technologists; contractors; civil engineers; consultants; government agencies; research organizations.
Concrete: We use it for our buildings, bridges, dams, and roads. We walk on it, drive on it, and many of us live and work within its walls. But very few of us know what it is. We take for granted this ubiquitous substance, which both literally and figuratively comprises much of modern civilization's constructed environment; yet the story of its creation and development features a cast of fascinating characters and remarkable historical episodes. Featuring a new epilogue on the Surfside condominium collapse and the current state of infrastructure in America, this book delves into this history, opening readers' eyes at every turn. In a lively narrative peppered with intriguing details, author Robert Courland describes how some of the most famous personalities of history became involved in the development and use of concrete-including King Herod the Great of Judea, the Roman emperor Hadrian, Thomas Edison (who once owned the largest concrete cement plant in the world), and architect Frank Lloyd Wright. Courland points to recent archaeological evidence suggesting that the discovery of concrete directly led to the Neolithic Revolution and the rise of the earliest civilizations. Much later, the Romans reached extraordinarily high standards for concrete production, showcasing their achievement in iconic buildings like the Coliseum and the Pantheon. Amazingly, with the fall of the Roman Empire, the secrets of concrete manufacturing were lost for over a millennium. The author explains that when concrete was rediscovered in the late eighteenth century it was initially viewed as an interesting novelty or, at best, a specialized building material suitable only for a narrow range of applications. It was only toward the end of the nineteenth century that the use of concrete exploded. During this rapid expansion, industry lobbyists tried to disguise the fact that modern concrete had certain defects and critical shortcomings. It is now recognized that modern concrete, unlike its Roman predecessor, gradually disintegrates with age. Compounding this problem is another distressing fact: the manufacture of concrete cement is a major contributor to global warming. Concrete Planet is filled with incredible stories, fascinating characters, surprising facts, and an array of intriguing insights into the building material that forms the basis of the infrastructure on which we depend.
Concrete will be the key material for Mankind to create the built environment of the next millennium. The requirements of this infrastructure will be both demanding, in terms of technical performance and economy, and yet be greatly varied, from architectural masterpieces to the simplest of utilities.This volume is a compilation of the Opening Addresses and Leader Papers for the five Conferences and fove Seminars held during the Congress, Creating with Concrete, 6-10 September 1999, organised by the Concrete Technology Unit, University of Dundee.

George Lindbeck wrote one of the most often read and debated theological works of the twentieth century, The Nature of Doctrine. Despite the work’s wide readership, few read the book considering his work as an ecumenist. In addition, few have read Lindbeck’s other writings. This work seeks to remedy this situation by providing (1) a context for understanding The Nature of Doctrine, (2) a corrective to misreadings of Lindbeck’s work, (3) an introduction to his broader corpus, and (4) some possible ways in which Lindbeck’s work can contribute to future ecumenical discussion and to Christian theological practice more broadly. It will do so by focusing upon several key roles or aspects of Lindbeck’s life and thought, from his understanding of his own Lutheran background and his participation in Lutheran-Catholic dialogue, to his training in medieval philosophy and theology and later work on the church as Israel.
Started in 1958, Sanathana Sarathi is a monthly magazine devoted to Sathya (Truth), Dharma (Righteousness), Shanti (Peace) and Prema (Love) - the four cardinal principles of Bhagawan Baba's philosophy. It is published from Prasanthi Nilayam (the Abode of Highest Peace) and acts as a mouthpiece of Baba's Ashram as it speaks of the important events that take place in His sacred Abode, besides carrying Divine Messages conveyed through Divine Discourses of Bhagawan Sri Sathya Sai Baba. The word meaning of Sanathana Sarathi is the 'Eternal Charioteer'. It signifies the presence of the Lord in every being as the atma guiding their lives like a charioteer. It implies that he who places his life, the body being likened to a chariot, in an attitude of surrender in the hands of the Lord, will be taken care of by the Lord even as a charioteer would take the occupant of his chariot safely to its destination. The magazine is an instrument to disseminate spiritual knowledge for the moral, physical and mental uplift of humanity without any discrimination as the subject matter discussed therein is always of common interest and of universal appeal. The fifteen Vahinis - streams of sacredness - known as the Vahini Series comprising annotation and interpretation of the Upanishads and other scriptures, Itihasas like the Ramayana, the Bhagavatha and the Mahabharata, and authentic explanations on Dhyana, Dharma, Prema, etc., have been serially published in this magazine as and when they emanated from the Divine pen of Bhagawan Baba. This magazine is published in almost all Indian languages, English and Telugu from Prasanthi Nilayam and others from respective regions. Every year Sanathana Sarathi comes out with a special issue in November commemorating the Divine Birthday. The English and Telugu magazines are posted on the 10th and 23rd respectively, of every month, from Prasanthi Nilayam. This magazine has wide, ever increasing circulation in India as well as abroad, as the study of it brings the reader closer to the philosophy of the Avatar in simple understandable language THUS SPAKE SAI... Discoursing during the launch of Sanathana Sarathi... From this day, our Sanathana Sarathi will lead to victory the cohorts of truth - the Vedas, the Sastras and similar scriptures of all faiths, against the forces of the ego such as injustice, falsehood, immorality and cruelty. This is the reason why it has emerged. This Sarathi will fight in order to establish world prosperity. It is bound to sound the paean of triumph when universal Ananda is achieved.
