text: the production of a safety manual for persons handling these substances. The manual, in three parts, contains comprehensive information on about 3,000 substances, including their chemical and physical properties, their potential hazards and the measures to be taken in the event of an emergency; (i) Design of construction system No. 5. This system, which is suitable for use by persons with limited means, is based on the use of concrete blocks which were specially designed by the Society. The system ensures rapid construction and allows scope for both vertical and horizontal expansion; it is also earthquake-resistant and provides excellent thermal insulation, thereby reducing energy consumption; (j) Use of photovoltaic cells and wind power for the development and electrification of remote areas and the pumping of water from deep wells; (k) Projects for the production of scientific reading books for children and young persons, translation of scientific and mathematical works, and conduct of scientific studies and research activities. 49. The Higher Council for Science and Technology was established on 1 December 1987 with a view to the establishment, preservation and development of a national scientific and technological base for the achievement of the objectives of socio-economic and cultural development in the Kingdom (art. 4 of Act No. 30 of 1987 establishing the Higher Council for Science and Technology). 50. In 1988, the Council pursued the following two principal objectives: formulation of scientific and technological policies, with associated plans, programmes and projects linked to the needs of the various developmental sectors; and establishment of priorities for research, development and the transfer of technology yielding socio-economic benefits consistent with world-wide technological progress, and formulation of appropriate strategies. 51. The authorities represented on the Council are those basically concerned with socio-economic and cultural development in the Kingdom and it is they who 
analysis: The text appears to be discussing various initiatives and projects aimed at promoting scientific and technological development in a kingdom, with a focus on providing a safety manual for handling hazardous substances, designing and constructing buildings, generating energy through renewable sources, and conducting scientific research and studies. These initiatives seem to be driven by a desire to achieve socio-economic and cultural development in the kingdom.
