  • Astronomers have studied the heavens for more than two millennia, but in the twentieth century, humankind ventured off planet Earth into the dark vacuum void of space, forever changing our perspective of our home planet and on our relationship to the universe in which we reside. Our explorations of space—the final frontier in our niche in this solar system—first with satellites, then robotic probes, and finally with humans, have given rise to an extensive space industry that has a major influence on the economy and on our lives. In 1998, U.S.

  • As populations increase and countries industrialize, the world’s demand for energy increases. Our supply of petroleum and gas is limited, but the photovoltaic cell offers a solution to the problem of a future energy shortage. This cell is already an important source of energy. In fact, it seems almost like magic. The photovoltaic cell changes sunlight directly into energy. Solar energy – energy from the sun – is clean, easily available, inexhaustible, and free, if the equipment is available....

  • When we talked to colleagues and friends during the last few months about our e-business book project, many of them asked whether we were arriving too late with this book. They reminded us that the Internet bubble had burst three years ago and that most online companies had since gone bankrupt. This is certainly true, yet we nonetheless believe that it is indeed a very timely moment to publish a book on e-business and strategy.

  • Recent advents in laser technology and discoveries in laser physics have enabled their very new and exciting applications. Some of them cover production of new materials: nano-particles, periodic structures in nano-scale, and thin films. Others allowed better understanding of laser-matter interaction when sample is subjected to intense laser pulses of various time duration, shape in space and time domains as well as different spectral components contained in a pulse.

  • Difficulty in addressing contamination in low permeability soils may be alleviated to some degree by controlled pneumatic or hydraulic fracturing of the soil. However, engineered hydraulic fractures generally cannot be spaced more closely than about 5 feet, which means that chemical oxidants must still penetrate a substantial thickness of low permeability soil to come into contact with the contamination. Deep soil mixing with large diameter drill augers is the most effective method currently available to increase contact between adsorbed contaminants and the oxidants.

  • Aluminium alloys have undergone a dramatic transformation in areas of extrusion, machining, welding, heat treatment, structural changes, created by ultra fine particles and enhanced corrosion resistance. Hence, these alloys have made rapid gains in European automotive and space industry. These developments have been described by experts in the book with new data and attractive graphics. The effect of processing parameters, including welding and deep rolling on their performance have been highlighted to alleviate the concerns of manufacturers and designers for new applications.

  • Important as is the rainfall in making dry-farming successful, it is not more so than the soils of the dry-farms. On a shallow soil, or on one penetrated with gravel streaks, crop failures are probable even under a large rainfall; but a deep soil of uniform texture, unbroken by gravel or hardpan, in which much water may be stored, and which furnishes also an abundance of feeding space for the roots, will yield large crops even under a very small rainfall. Likewise, an infertile soil, though it be deep, and under a large precipitation, cannot be depended on for...

  • One factor that discourages the use of new organizational techniques is the dependence of email clients, legacy file systems, and other applications on their own independent hierarchical structures. We agree with Boardman [Boardman02] that folder structures should be integrated – in our case, also integrated with our more flexible collection structure. Reporting tools with appropriate visualization are another class of very useful apps. A simple query based tool can be remarkably insightful and useful from “how I spend my time” to “count and space used” by different items.

But the agencies responsible for those pictures, other missions to Earth orbit, and probes to deep space are inevitably national or multinational. Each has its own set of constituencies, procedures, capabilities, and limitations.

  • Much has been written in the West on the history of the Soviet space program but few Westerners have read direct first-hand accounts of the men and women who were behind the many Russian accomplishments in exploring space.The memoirs of Academician Boris Chertok, translated from the original Russian, fills that gap. Chertok began his career as an electrician in 1930 at an aviation factory near Moscow.Twenty-seven years later, he became deputy to the founding figure of the Soviet space program, the mysterious “Chief Designer” Sergey Korolev. Chertok’s sixty-year-long career an...

  • The luxury goods industry is unique in that it is an industry that relies strictly on marketing and promotion to sell products to a specified group of people. It is also an industry that is well guarded and difficult to find any information on. However, the luxury goods industry is very fascinating and the products themselves signify prestige and status. Although a select few are able to afford luxury goods, the vast majority of people who are exposed to advertisements for certain products generally have aspirations of being able to own these products someday. ...

  • This brings us to the most complicated issue of Pakistan’s Dairy supply chain namely; achieving a “Level Playing Field” between the middlemen Dhodhis and the processors. At present, middlemen play a critical role in the Pakistan dairy industry: Without them, a far smaller proportion of milk would find its way from the farmer to the consumer. To varying extents, processors rely on dhodhis collecting milk and transporting it to collection centers. It is well known that adulteration of milk occurs in Pakistan on a broad scale.

  • Our study assessed the opportunity for library space saving and cost avoidance through the systematic and intentional outsourcing of local management operations for digitized books to shared service providers and progressive downsizing of local print collections in favor of negotiated access to the digitized corpus and regionally consolidated print inventory. As detailed in the report that follows, the organizational change required to achieve these gains is likely to be substantial and challenging to implement.

  • Despite the long-established recommendations and public health messages, the population is still failing to achieve a healthy balanced diet. To date public health messages for dietary intakes have focused on the impact on health outcomes and have not addressed any of the wider issues relating to sustainability. It is recognised that this could be complex, but it is important to add some of the wider issues of sustainability into current dietary advice if a single, consistent message about the diet is to be given to the public, government and industry.

  • The last edition of the report came out soon after the onset of the global financial crisis, leaving out little scope for incorporating a detailed analysis of its impact on the media industry. We have tried to more than compensate for that in the present edition, providing a much more focused assessment of the media industry against the backdrop of the financial meltdown. The impact of the crisis, needless to say, varies from country to country, depending on the extent to which each market is exposed to global markets.

  • Some sites are presented as virtual cities where digital individuals live their lives parallel to the ‘real ones’, some promote the images of real cities being an increasingly important place marketing tool. Especially the most iconic global tourist cities provide images that aim to give to these material places new meaning in the virtual space. Apart from being part of the virtual realm, webcams can, indeed, create ‘real interest on a real place’ adding to them “a whole new stratum of cultural space” (Campanella, 2004: 59).
