  • The automobile has come to symbolize the essence of a modern industrial society. Perhaps more than any other single icon, it is associated with a desire for independence and freedom of movement; it is an expression of economic status and personal style. Automobile production is also critically important to the major industrial economies of the world. In the United States, for instance, about 5 percent of all workers are employed directly (including fuel production and distribution) by the auto industry.

  • In a 1786 letter to a friend, Thomas Jefferson called for “the diffusion of knowledge among the people. No other sure foundation can be devised for the preservation of freedom and happiness.”1 Jefferson saw clearly what has become increasingly evident since then: the fortunes of a nation rest on the ability of its citizens to understand and use information about the world around them. We are about to enter a century in which the United States will be even more dependent on science and technology than it has been in the past.

  • The discovery and utilization of fire, a simple energy source with many profound uses, was a turning point in the technological evolution of humankind.[26] The exact date of its discovery is not known; evidence of burnt animal bones at the Cradle of Humankind suggests that the domestication of fire occurred before 1,000,000 BC;[27] scholarly consensus indicates that Homo erectus had controlled fire by between 500,000 BC and 400,000 BC.

  • VNU Journal of Science, Natural Sciences and Technology 26 (2010) 161-164 Fresh leaves of Litsea glutinosa (Lour.) C. B. Rob. from Ha Tinh were steam distilled to produce an oil in 0.15% yield. The essential oil was analysis by a combination of capillary GC and GC/MS. Seventy eight compounds were detected in the oil, of which more than 95.18% were terpenoids. The major components were (E)-β-ocimene (13.35%), β-caryophyllene (27.20%) and bicyclogermacrene (18.16%).

  • This study focuses on incentives that target small-scale renewable energy technologies intended for on-site use in residential or small commercial applications. Solar and small wind were naturally the primary relevant technologies given this scope. For incentives that were available to owners of large- and small-scale systems, the discussion centers primarily on the impact of the incentive on smaller applications.

  • The United States has been in the process of destroying its chemical munitions for well over a decade. Initially, the U.S. Army, guided by recommendations from the National Research Council (NRC), decided to use incineration as its destruction method at all sites. However, citizens in some states with stockpile storage sites oppose incineration on the grounds that the exact nature of the effluents escaping from the stacks cannot be determined.

  • The medical devices industry is booming. Growth in the industry has not stopped despite globally fluctuating economies. The main reason for this success is probably the self-sustaining nature of health care. In essence, the same technology that makes it possible for people to live longer engenders the need for more health-care technologies to enhance the quality of an extended lifetime. It comes as no surprise, then, that the demand for trained medical-device designers has increased tremendously over the past few years.

  • The industry approach to environmental issues has moved from ‘end-of-pipe’ solutions, towards a pollu- tion prevention strategy. This strategy requires an integrated, holistic view of activities. Tools have been developed to assist management, including cleaner production, life cycle assessment and industrial ecolo- gy. Each of these looks at the life cycle of the product or service, to identify where the major environmental issues or problems may arise and where the most cost- effective solutions can be developed.

  • The process, as described in step (c) is repeated for a shorter time to expose the bottom silicon surface for further dry etching, as shown in Fig. 9(g). In order to expose sidewalls for the wet etch release, the structure is deepened using a similar multi-step dry etch process as described in step (d), except that low energy, high pressure isotropic dry etching is used instead of high energy, high pressure to preserve the less robust silicon dioxide that had taken the place of Cr as the etch mask. This deepening of the structure determines the gap between the...

  • Fe3O4 nanoparticles have been prepared by the microemulsion technique with water as the aqueous phase, n-hexane as the oil phase and Span 80 as the surfactant. The reaction occurred under air, N2 or high temperature and high pressure atmosphere. Particle size can be controlled by the concentration of the reactants dissolved in water, the ratio of water/surfactant and the atmospheric conditions.
