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.
During the last two decades, increase in electricity demand and environmental
concern resulted in fast growth of power production from renewable sources. Wind
power is one of the most efficient alternatives. Due to rapid development of wind
turbine technology and increasing size of wind farms, wind power plays a significant
part in the power production in some countries.
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....
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.
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.
Globally, we are utilizing government benchmarking
programs to measure performance and comply with local
and federal regulations and disclosure requirements. these
include programs such as EnERGy staR in the u.s.,
Energy performance Certificates (EpCs) across Europe, the
national australian built Environment Rating system
(nabERs), and the Comprehensive assessment system for
built Environment Efficiency (CasbEE) in Japan.
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.
Victoria Johnson is a rock star, but not just any rock
star. She’s not backing down from heralding a self-love, selfempowerment,

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
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....
Researchers are trying to meet the challenge posed by the rapidly evolving landscape
of sustainability. All in all, a lot has been done but a lot more needs to be done on the
part of researchers to meet the pace of the sustainability movement. In order to
address the sustainability deficit in education and research, InTech has invited
submissions of manuscripts for publication in its focused issue on sustainability.
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.
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.
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
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...
