September 18-20, 1991 International Conference Manchester, on Earthquake, Blast and Impact England Organised by the Society for Earthquake and Civil Engineering Dynamics, this conference will bring together clients, consultants, contractors, manufacturers, academics and researchers to discuss the state of the art and future developments in this field. Particular emphasis will be given to the measurement and testing of the dynamic behavior of structures and structural elements, and their effects on plant and people. The muin emphasis will be on: Sources and measurement (earthquake, blast, shock, impact); Response and measurement (displacement and stresses); Industrial case histories (plantYequipment/structures); Testing equipment (on site/in laboratory); Construction effects (piling and demolition); Analysis and design aspects; Code issues; and Mitigation of effects. Call for papers: Anyone wishing to present a paper should submit two copies of a typed abstract (200-500 words) by August 31, 1990, to the ICE Conference Office.

Call for Papers: Send a 500-word abstract, in duplicate, by September 1, 1990, to the following address: Dr. Ilan Juran, Dept. of Civil Engineering, Louisiana State University, Baton Rouge, LA 70803 U.S.A. Tel. (504) 3888699. Fax: (504) 388-5990. August 23-26, 1993 International Congress o n Kingston, Ontario, C a n a d a Mine Design "Mining into the 21st Century" is the theme of this congress, which is sponsored by the Queen's University Faculty of Applied Science and the Canadian Institute of Mining and Metallurgy. The congress is intended to establish a forum in which to discuss state-of-the-art technology, innovative mining practice, and the anticipated evolution of mining trends. The international scope of the forum will be used to introduce global changes in technology that will shape the future of world mining into the next century. Plenary papers discussing mine design and pecific regional problems from all continents will promote a global interchange of mining technology. Parallel specialty sessions will cover advances in specific topic areas, including computer applications; backfill technology; microseismic technology; mine automation and materials handling; blasting technology; open pit technology; underground support design; mine sequencing; mine ventilation; mine dewatering; and instrumentation technology. A trade show will feature displays of the latest in mining equipment and technology, including heavy equipment and automated machinery demonstrations. Official languages of the congress are English and French. The first call for papers will be issued in January 1991.
