Tahir Shah – författare

The monograph critically reviews most commonly used geotextile structures, their properties and performance characteristics. In general, both natural and synthetic fibres are used for the production of geotextiles, and the advantages and disadvantages of each type of fibre are discussed for various applications of geotextiles. The important functions of geotextiles, i.e. filtration, drainage, separation and reinforcement have been identified and have been related to several properties and major applications of geotextiles. Various geotextile properties, namely mechanical, hydraulic and chemical and their test methods have been critically discussed. A process-structure-property relationship for most commonly used geotextiles is also analysed. Furthermore, the design of a geotextile is of paramount importance for any civil engineering application. Thus, the design criteria for various functions of geotextiles have been addressed. Subsequently, the durability characteristics of geotextile have been introduced for analysing the performance over its lifetime.

Look into the eyes of a jinn and you stare into the depths of your own soul...Writer and film-maker Tahir Shah - in his 30s, married, with two small children - was beginning to wilt under brash, cramped, ennervating British city life. Flying in the face of friends' advice, he longed to fulfil his dream of finding a place bursting with life, colour, history and romance - somewhere far removed from London - in which to raise a family. Childhood memories of holidaying with his parents, and of a grandfather he barely knew, led him to Morocco and to 'Dar Khalifa', a sprawling and, with the exception of its jinns, long-abandoned residence on the edge of Casablanca's shanty town that, rumour had it, once belonged to the city's Caliph. And so begins Tahir Shah's gloriously vivid, funny, affectionate and compelling account of how he and his family - aided, abetted and so often hindered by a wonderful cast of larger-than-life local characters: guardians, gardeners, builders, artisans, bureacrats and police (not forgetting the jinns, the spirits that haunt the house) - returned the Caliph's House to its former glory and learned to make this most exotic and alluring of countries their home. The Caliph's House is a story of home-ownership abroad - full of the attendant dramas, anxieties and frustrations - but it is also much more. Woven into the narrative is the author's own journey of self-discovery, of learning about a grandfather he hardly knew, and of coming to love the magical, multi-faceted, contradictory country that is Morocco.

Shortly after the 2005 London bombings, Tahir Shah was thrown into a Pakistani prison on suspicion of spying for Al-Qaeda. What sustained him during his terrifying, weeks-long ordeal were the stories his father told him as a child in Morocco.Inspired by this, on his return to his adopted homeland he embarked on an adventure worthy of the mythical Arabian Nights, going in search of the stories and storytellers that have nourished this most alluring of countries for centuries. Wandering through the medinas of Fez and Marrakech, criss-crossing the Saharan sands and tasting the hospitality of ordinary Moroccans, he collected a treasury of traditional stories recounted by a vivid and eccentric cast of characters: from master masons who work only at night to Sufi wise men who write for soap operas and Tuareg guides addicted to reality TV. Himself a link in the chain of scholars and teachers who have passed such tales down from father to son, mother to daughter, Shah reveals a world and a way of thinking that most visitors to Morocco barely know exist.
