  • By the middle of the seventeenth century it had come to be understood that the world was enclosed in a sea of air, much as the greater part of it was covered by water. A scientist of the period, Francesco Lana, contended that a lighter-than-air ship could float upon this sea, and he suggested how such a ship might be built. He was unable to put his invention to a practical test, but he saw only one reason why it might not work:

  • ver fifty years ago, Vannevar Bush released his enormously influential report, Science, the Endless Frontier, which asserted a dichotomy between basic and applied science. This view was at the core of the compact between government and science that led to the golden age of scientific research after World War II--a compact that is currently under severe stress. In this book, Donald Stokes challenges Bush's view and maintains that we can only rebuild the relationship between government and the scientific community when we understand what is wrong with that view.

  • Anorexia nervosa and bulimia nervosa are characterized by severe disturbances of eating behavior. The salient feature of anorexia nervosa (AN) is a refusal to maintain a minimally normal body weight. Bulimia nervosa (BN) is characterized by recurrent episodes of binge eating followed by abnormal compensatory behaviors, such as self-induced vomiting. AN and BN are distinct clinical syndromes but share certain features in common. Both disorders occur primarily among previously healthy young women who become overly concerned with body shape and weight. ...

  • This paper presents the experiences gained from ongoing research collaboration between the School of Computer Engineering at Nanyang Technological University and the Southampton e-Science centre at the University of Southampton using a serviceoriented approach for complex engineering design optimization. The service-oriented approach enables programmatic collaboration to be realized while maintaining the autonomy of individual codes at the different institutes and organizations. In the current work, a Genetic algorithm optimization logic implemented as a Grid...

  • The third stage characterizes the progression to professional expertise in writing. The writer must maintain and manipulate in working memory a representation of the text that might be constructed by an imagined reader as well as the author and text representations. Notice that this stage now involves modeling not just the reader's view of the writer's message but also the reader's interpretation of the text itself. In knowledge-crafting, the writer shapes what to say and how to say it with the potential reader fully in mind.

  • During biosynthesis of chlorophyll, Mg 2+ is inserted into protoporphyrin IX by magnesium chelatase. This enzyme consists of three different subunits of 40, 70 and 140 kDa. Seven barley mutants deficient in the 40 kDa magnesium chelatase subunit were analysed and it was found that this subunit is essential for the maintenance of the 70 kDa subunit, but not the 140 kDa subunit. The 40 kDa subunit has been shown to belong to the family of proteins calledATPases associated with various cellu-lar activities, known to form ring-shaped oligomeric complexes working as molecular chaperones....

  • This module outlines the basic mechanics of elastic response | a physical phenomenon that materials often (but do not always) exhibit. An elastic material is one that deforms immediately upon loading, maintains a constant deformation as long as the load is held constant, and returns immediately to its original undeformed shape when the load is removed. This module will also introduce two essential concepts in Mechanics of Materials: stress and strain
