  • Flight controls have advanced considerably throughout the years. In the earliest biplanes flown by the pioneers flight control was achieved by warping wings and control surfaces by means of wires attached to the flying controls in the cockpit. Figure 1.1 clearly shows the multiplicity of rigging and control wires on an early monoplane. Such a means of exercising control was clearly rudimentary and usually barely adequate for the task in hand.

  • Many American history books begin with the year 1492 and the discovery of the Caribbean Islands by Spanish explorer Christopher Columbus (1451–1506).

The products of thousands of years of history—the cities, the architecture, markets, governments, economic systems, legal systems, schools, books, holy shrines—even the daily prayers of the people—were about to be willfully eliminated by the conquering European nations.

By the Second World War, technology began to be integrated into combat. The invention of radar and sonar extended the field of combat to greater and greater ranges, and it was no longer necessary to sight targets directly. As technology progressed, the very nature of weapons also changed. Now, it is no longer sufficient to discuss individual pieces of weaponry, they must be taken in the context of...

  • The oviduct is an exquisitely designed organ that functions in picking-up ovulated oocytes, transporting gametes in opposite directions to the site of fertilization, providing a suitable environment for fertilization and early development, and transporting preimplantation embryos to the uterus. A variety of biological processes can be studied in oviducts making them an excellent model for toxicological studies.

  • Rheumatoid arthritis is a chronic systemic inflammatory arthritis of auto-immune origin that affects primarily the synovial joints, usually in a symmetrical pattern. It is the most common and most serious of the inflammatory arthritides, and it dominates clinical rheumatological practice (Silman 2002). Current evidence shows that prompt diagnosis and early instigation of definitive disease-modifying treatment can delay or avoid progression and enable patients to retain function that would otherwise be lost in this progressive and frequently disabling disease....
