    The Projected Al Qaeda Use of Body Cavity Suicide Bombs Against High Value Targets

    This work is initially derived from a non-public disclosure series of early warning presentations, first delivered in September 2006, by the author on the projected terrorist use of body cavity suicide bombs against high value targets. Subsequent terrorist use of such a device, in August 2009 in Saudi Arabia by an Al Qaeda operative, has allowed for this body of research (along with post-incident analysis) to now be published in an open venue. The work provides a historical overview of the use of suicide bombs by military forces and terrorists; addresses the co-evolution of suicide bombs and countermeasures by security groups; analyzes future suicide bomb placement options; and explores Islamic views on the acceptability of foreign object placement in body cavities. It then focuses on issues pertaining to body cavity bomb placement options; bomb components, assembly, and detonation issues; putty, cheese, and the Fadhel al-Maliki incident; Al Qaeda use validation— the Abdullah al-Asiri incident; and concludes with a discussion on body cavity bomb countermeasures and strategic use implications. The work signifies the value of early warning and futures analysis applied to counter-terrorism activities and also highlights the tensions and inherent contradictions involved with individuals who wear the dual hats of practitioner and scholar. These individuals, given the requirements of operational security and secrecy, are challenged with ensuring that open discourse and publication in no way threatens the greater public good

    The goal of the Fall 1987 class of EGM 4000 was the investigation of engineering aspects contributing to the development of NASA's Controlled Ecological Life Support System (CELSS). The areas investigated were the geometry of plant growth chambers, automated seeding of plants, remote sensing of plant health, and processing of grain into edible forms. The group investigating variable spacing of individual soybean plants designed growth trays consisting of three dimensional trapezoids arranged in a compact circular configuration. The automated seed manipulation and planting group investigated the electrical and mechanical properties of wheat seeds and developed three seeding concepts based upon these properties. The plant health and disease sensing group developed a list of reliable plant health indicators and investigated potential detection technologies

    A History of Materials and Technologies Development

    Get PDF
    The purpose of the book is to provide the students with the text that presents an introductory knowledge about the development of materials and technologies and includes the most commonly available information on human development. The idea of the publication has been generated referring to the materials taken from the organic and non-organic evolution of nature. The suggested texts might be found a purposeful tool for the University students proceeding with studying engineering due to the fact that all subjects in this particular field more or less have to cover the history and development of the studied object. It is expected that studying different materials and technologies will help the students with a better understanding of driving forces, positive and negative consequences of technological development, etc
