The play pokes fun at social climbing Monsieur Jourdain. 1979-01-01T00:00:00Z https://www.um.edu.mt/library/oar/handle/123456789/20422 Title: Polymers Abstract: From the chemical point of view, polymers comprise long molecules in which the same basic unit is replaced many times. Polyvinyl chloride, P.V.C., a typical polymer consists of vinyl chloride units linked together. Polymers occur widely in nature. In the inorganic world, rocks, clays and sands are all polymers based on units containing silicon and oxygen. In the organic realm, the structural materials of living organisms are polymers: cellulose in plants and proteins in animals. The products of metabolism of plants and animals may also be polymeric. One important example is natural rubber - a long chain of isoprene units. In physical properties most polymers fall into one of the three classes - plastics, rubbers and fibres. Some polymeric materials can be stretched to many times their initial length, yet on releasing return to their original dimensions. These are called rubbers. Plastics cannot be reversibly deformed in this manner, and are often hard and glassy. Nylon and other high polymers are characterised by marked readiness to form fibres strong along their length but often weak laterally. Such man-made fibres can be spun woven or knitted into fabrics. 1979-01-01T00:00:00Z https://www.um.edu.mt/library/oar/handle/123456789/20420 Title: A brief account of territorial behaviour in animals Abstract: Hitler called it Lebensraum. Some are of the opinion that it is the cause of all capitalistic evils, while others defend it as an essentially basic human right. The acquisition of private property and the passion for a place of one's own is at the root of many of our economic and political issues. It may come as a surprise to some that this is no passion which man has acquired as a result of his culture or society. As an instinct, territorial behaviour - the need to acquire and defend a place of one's own, is widespread amongst many animals. 1979-01-01T00:00:00Z
