  • The most important function of lubricants is the reduction of friction and wear and in some cases, the relative movement of two bearing surfaces is only possible if a lubricant is present. In times when saving energy and resources and cutting emission have become central environmental matters, lubricants are increasingly attracting public awareness. Scientific research has shown that 0.4% of gross domestic product could be saved in terms of energy in Western industrialized countries if current tribological knowledge, i.e.

  • What does a Distributer do? While Distributers are invisible to most consumers their role is to bridge the geographical gap between producer and retailer. Supermarkets and department stores couldn't exist without a complicated distribution system, capable of moving enormous amounts of product from point A – the producer to point C – the consumer. Distributors add significantly to the cost of the products we buy but they deliver a valuable service in providing access to the marketplace so producers can focus their energies on manufacturing the product.

  • In my forty years within the natural health movement, I’ve been blessed to witness the living food lifestyle spread its wings and soar. When I started the Hippocrates Health Institute with Dr. Ann Wigmore in the 1960s, “raw” and “living” were not words commonly associated with the way we eat. I developed a living foods program, a radically new paradigm at the time, which demonstrated unquestionable healing powers. One by one people would arrive at the Institute with grave illnesses and depart revitalized by the simple preparations created from the uncooked bounty of nature....

  • MOST OF US are familiar with the observation that house plants placed near a window have branches that grow toward the incoming light. This response, called phototropism, is an example of how plants alter their growth patterns in response to the direction of incident radiation. This response to light is intrinsically different from light trapping by photosynthesis. In photosynthesis, plants harness light and convert it into chemical energy (see Chapters 7 and 8). In contrast, phototropism is an example of the use of light as an environmental signal.

  • Water and energy are two critical ingredients of modern civilization. Without clean water, life cannot be sustained. Without energy, we cannot run computers, power homes or manufacture products. As the world’s population grows in number and affluence, demand for both resources is increasing faster than ever, with far-reaching implications for both water scarcity and rising levels of global warming pollution. Woefully underappreciated, however, is the fact that water and energy oftentimes compete with one another.

  • The energy crisis of the mid 1970’s gave birth to a movement to conserve energy. Over the ensuing years much has been done to reduce the energy consumption of new and existing buildings. Lighting efficiency has improved so much that today we use ½ the wattage without sacrificing lumens. Improved construction methods, better insulation and high efficiency windows have also helped reduce energy consumption. However, all of these measures have resulted in a reduction of Sensible heat gains while Latent heat gains have increased.

  • Through the efforts of a wide array of public and private organizations around the globe, a strong and growing movement is beginning the process of transforming the systems that create the built environment from ones that pay no attention to resources and the environment to a new variety in which these considerations are the pre-eminent criteria for “good” construction. Although dating back only to the early 1990s, there is already ample evidence that the “green building” movement is affecting the design, construction, operation, and disposal of the built environment....

  • Green projects - particularly sustainable energy sources and clean technology - include multiple technologies, at different stages of maturity, and require different types of financing vehicle. Most pension funds are more interested in lower risk investments which provide a steady, inflation adjusted income stream - with green bonds consequently gaining interest as an asset class, particularly - though not only - with the SRI universe of institutional investors.

  • The way we design, plan and build our cities and their infrastructure is critical for developing competitive and liveable cities. Cities are already suffering from severe environmental problems, such as pollution, congestion and excessive waste, while the basic needs of hundreds of millions of urban residents are yet to be met. The unprecedented urbanization imposes an even greater challenge for providing adequate housing, energy, water, sanitation and mobility to all. Cities are at a crossroads.

  • This paper describes the work performed on two programs supported in part by the U.S. Department of Energy. These programs are aimed at evaluating the potential of using slurries of chemical hydrides and organic liquids to store hydrogen. The projects have been very successful in meeting all project objectives. After a detailed analysis of chemical hydrides, lithium hydride was selected for use in these programs.

  • The environmental justice movement brings together all elements of the social justice movement, espousing a more holistic definition of environment that embraces public health, economic development, housing, energy and transportation as well as preservation of natural resources. Environment is defined as where we live, work, learn and play. As children of the larger civil rights movement, environmental justice advocates organize from the bottom up and seek to cultivate and empower community-based leadership.

  • I am think- ing here of Allan Kaprow, John Cage, or George Maciunas. They sensed that the depictive arts could not be displaced by any more upheavals from within, any more radical versions of depic- tion or anti-depiction. They came to recognize that there was something about the depictive arts that would not permit an- other art form or art dimension to evolve out of them. The new challenge to western art would be advanced in terms of move- ment and the arts of movement. Cage’s piano concert, 4’33”, first presented in 1952, can be seen as the first explicit statement of this...

  • When I began research for the Nutrition Almanac in the early seventies, scientific information on health and nutrition was scarce and difficult to find. In recent years, however, there has been a plethora of studies and most are easier to access. The database of the National Library of Medicine, for example, lists over 40,000 articles specifically on alternative medicine. Alternative therapies focus on the underlying cause.

  • Similarly, the reverse movement represents a decrease in demand. The beauty of the connection between demand and marginal value is that an increase in demand could in principle have meant either more units demanded at a given price, or a higher willingness to pay for each unit, but those are in fact the same concept – both create a movement up and to the right. For many goods, an increase in income increases the demand for the good. Porsche automobiles, yachts, and Beverly Hills homes are mostly purchased by people with high incomes. Few billionaires...
