ANNOUNCEMENTS MECHANICS
OF
FIBROUS
STRUCTURES
A special course Of lectures on the Mechanics of Fibrous Structures has been arranged at the University of Manchester Institute of Science and Technology, Sackville Street, Manchester 1, to be given during 3 to 7 July next. It is hoped the following will be among the lecturers: R. ARRIDGE, S. BACKER, H. CORTE, P. GROSBERG, J. C. HALPIN, J. W. S. HEARLE, M. KONOPASEK, E. SMITH and S. W. TSAI. Subjects for the lectures will include the engineering approach to textiles; general methods of analysis; structural mechanics of fibres, yams, woven and knitted fabrics, non-woven fabrics, fibre-reinforced materials, paper, and fabricated textiles; use of computer methods and of dynamic modulus measurements. Application forms and details can be obtained from the Registrar, at the address given above. CONFERENCE
