The Committee to Review Assembled Chemical
Weapons Alternatives Program Detonation Technologies
was appointed by the National Research Council
(NRC) in response to a request by the U.S. Army’s
Program Manager for Assembled Chemical Weapons
Three types of detonation technologies available
from technology vendors and the Army’s explosive
destruction system (EDS), collectively known as
explosive destruction technologies (EDTs), are being
considered for use at the Blue Grass Army Depot in
Richmond, Kentucky, and the Pueblo Chemical Depot
in Pueblo, Colorado....
In terms of both speed and memory consumption, graph uniﬁcation remains the most expensive component of uniﬁcation-based grammar parsing. We present a technique to reduce the memory usage of uniﬁcation algorithms considerably, without increasing execution times. Also, the proposed algorithm is thread-safe, providing an eﬃcient algorithm for parallel processing as well.
Resonant frequency measurements provide useful insight into the
repeatability of MicroElectroMechanical Systems (MEMS) manufacturing
processes. Several techniques are available for making this
On close examination, the glowing promise of coal quickly turns to ash. Coal mining remains a deadly and environmentally destructive industry. Nearly forty percent of the carbon dioxide released into the atmosphere each year comes from coal-fired power plants. In the last two decades, air pollution from coal plants has killed more than half a million Americans. In this eye-opening call to action, Goodell explains the costs and consequences of America's addiction to coal and discusses how we can kick the habit....
After the ore is extracted, it is generally transferred by
bridge conveyor, shuttle cars or load-haul-dump units
to a system of conveyors that carry it to underground
storage bins, prior to haulage to the surface through a
shaft by automated skips. On rare occasions shallow
mines may use a decline and conveyor arrangement.
Solution mining is currently used at a number of
operations in North America. The process relies on
the greater solubility at elevated temperatures in brine
of sylvite in comparison to salt (NaCl).
“Junk” bonds, as they are popularly called, or “high-yield’’
bonds, as they are termed by those wishing to avoid pejorative
connotations, are simply bonds that are either rated below
investment grade or unrated altogether.’ Fueled by the introduction
of newly issued junk bonds in 1977, this segment of
the bond market has grown rapidly in recent years and now
accounts for more than 15 percent of public corporate bonds
outstanding. However, the growth of junk bond financing, particularly
in hostile takeover situations, has been bitterly
Hydraulic fracturing is an industrial process used to extract fossil fuel reserves that
lie deep underground. With the introduction of horizontal drilling, new commercial sources
of energy have become available. Wells are drilled and injected with large quantities of water
mixed with specially selected chemicals at high pressures that allow petroleum reserves to
flow to the surface. While the increased economic activities and the outputs of domestic energy
are welcomed, there is growing concern over negative environmental impacts from horizontal
drilling in shale formations.
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 chapters that follow offer fi rst-person accounts of the career journeys of
13 distinguished social psychologists. The authors describe their personal
career journeys, the signifi cant people and events that infl uenced their
paths, the major turning points, the main decisions, the challenges, the opportunities
and setbacks they experienced, and how the lessons they learned along the way
may shine a beacon for future social psychologists. Taken together, these chapters
chronicle the history of modern social psychology.
Criminals (thieves, terrorists, competitors, employees, etc.)—Criminal scenarios in-
clude simply gathering information that would give knowledge of the buildings and
how to break in, or maybe getting into the security system and having doors open.
DoS attacks could be used for a variety of purposes including: making a political
statement, interfering with business, etc. Terrorists could use low security on a net-
work to shut down facility operation (i.e. as a smokescreen or disruption) that facili-
tates other destructive activity.
Volcanic eruptions are awesome and destructive; however, this natural phenomenon
is beneficial in the long term. One of the earliest known written records
of a natural disaster concerned the eruption of Pompeii in A.D. 79, and was
recorded by Pliny the Younger in his letters to the historian Tacitus (Jashemski,
1979). Volcanic eruptions, ranging in intensity and numbering between 17 and
27 per year during the past decade (Bullard, 1984), continue to remind us of
their potential impacts on the environment.
Metaphorically, achievements, ideas, and theories are often seen as buildings, with an idea or the
process of achieving something being similar to the process of building, and the failure of something
being similar to the destruction of a building. Metaphorically, ideas are also like plants, and
developing an idea is like getting plants to grow.
The biological changes underlying the transition process from gingival health to early
inflammatory changes involve local increase in vascular permeability, edema and the
recruitment and activation of polymorphonuclear neutrophils (PMN) (Delima and Van
Dyke 2003). Acquired immune response becomes involved once antigen-presenting cells
interact with immunocompetent cells, such as T and B lymphocytes, leading to the
expansion of antibody-secreting plasma cells and the development of the chronic lesion
(Gemmell and Seymour 2004).

Myocarditis is a clinical syndrome characterized by inflammation of myocardium. It can be
produced by a myriad of etiologies including infectious, autoimmune, myocardial toxins,
hypersensitivity reactions and physical agents. Virtually any infectious agent can produce
myocardial inflammation and injury. Human myocarditis is most frequently caused by viral
infection. Ongoing viral infection, myocardial destruction, and adverse remodeling can lead
to persistent ventricular dysfunction and dilated cardiomyopathy.
The short life span of mature blood cells requires their continuous replacement, a process termed
hematopoiesis. New cell production must be responsive to both basal needs and situations of
increased demand. For example, red blood cell production can vary over more than a fivefold range
in response to anemia or hypoxia. White blood cell production increases dramatically in response to
a systemic infection, and platelet production can increase severalfold when platelet destruction
results in thrombocytopenia....
Nature has created numerous elegant living systems, including the human, based on the
hierarchical functional units—molecule, cell, tissue, and organ. A living system develops
through a long evolutionary process, during which the system undergoes genotypic and
phenotypic changes in response to environmental simuli.
process both reduces collagen synthesis by
inhibiting the smooth muscle cell and causes its
death by apoptosis. Macrophages also produce
a wide range of metalloproteinases capable of
degrading all the components of the connective
tissue matrix, including collagen. These metalloproteinases
are secreted into the tissues in an
inactive form and then activated by plasmin.
Metalloproteinase production by macrophages
is upregulated by inflammatory cytokines such
