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. 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; scholarly consensus indicates that Homo erectus had controlled fire by between 500,000 BC and 400,000 BC.
The dynamic nature of the Jepara industrial complex also affects the Indonesian wood products
chain, attracting timber produced from forests located throughout Central Java (Figure 1) and
beyond, including the outer islands. Thousands of trucks and pickups bring logs into the district
from distant places, including state and community forest plantations.
Biometrics-Unique and Diverse Applications in Nature, Science, and Technology provides a unique sampling of the diverse ways in which biometrics is integrated into our lives and our technology. From time immemorial, we as humans have been intrigued by, perplexed by, and entertained by observing and analyzing ourselves and the natural world around us.
Some events may appeal to terrorists for a number of reasons, including an anniversary
date, religious holiday, a particular location, the nature of the event, or those who will be
included among the participants. Communities can identify terrorist organizations that may
be attracted to their event for any number of reasons and can prepare accordingly.
Knowledge is an advantage. Know the possible risks that the event poses and the audience
that the event will attract.
Some larger businesses and industrial establishments have medical practitioners,
advisors or physicians on site or on payroll. Smaller businesses may not currently staff
In preparing your business continuity plan, it is advisable that you ensure access to a
medical practitioner or advisor for assistance and advice in the event of a pandemic. If
your company already has medical staff on site, they should be made aware of the
nature of the disease, how it is transmitted, its symptoms and health care precautions
available and appropriate.

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.
Evidence-based medicine (EBM) has been famously characterized by
David Sackett as the “conscientious, explicit, and judicious use of current
best evidence in making decisions about individual care.” The central
in EBM of the importance of integrating individual clinical expertise
with the best available external evidence provides a helpful framework for
providers navigating the uncertainty inherent in patient care.
Rapid improvements in health and nutrition in developing
countries may be ascribed to specific, deliberate, health- and
nutrition-related interventions and to changes in the underly-
ing social, economic, and health environments. This chapter
is concerned with the contribution of specific interventions,
while recognizing that improved living standards in the long
run provide the essential basis for improved health.
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.
