TECHNOLOGY & MATERIAL 1. There’s no arguing that technology has helped make life easier. Americans use it every day to communicate‚ travel‚ build and entertain themselves‚ but is it all positive? Does technology replace that which makes us human? Is technology harmful to the preservation of cultural values? Think about these questions as the effects of technology and material on American culture are explored. In the first point‚ the production element of technology and material will be covered

The respiratory system of the horse is well adapted to athletic exercise‚ with unrestricted upper airway diameters‚ and a large lung capacity afforded by 18 ribs. These combine to enable air intakes of up to 1800 litres per minute in a galloping horse. Volumes of up to 300 litres of blood are pumped at high pressure through small lung capillaries surrounding 10 million air sacs to take up and deliver over 70 litres of oxygen per minute to the working muscles at the gallop. As a result‚ any restriction

Introduction To Indian Pharmacompanies The pharmaceutical industry of India has matured over the years into a major producer of bulk drugs‚ rated among the top five in the world. The industry is largely concentrated in the production of ‘generics’ on account of the Process Patent Law introduced in the seventies (repealed under the recent TRIPS Agreement). India has since been able to establish technological capability for manufacture and supplying of generic drugs. This ‘generics capability’ of
