Explosives and propellants contain considerable chemical energy that can be converted into rapid expansion. In contrast to the simple burning of a fuel, explosives and propellants are self-contained and do not need an external supply of oxygen via air. Since their energy content inherently creates the risk of accidental triggering of the explosive reaction, the correct synthesis, formulation, and handling during production and use are of utmost importance for safety, necessitating specialist knowledge on energetic materials, their characteristics, handling and applications.
Although allostery plays a central role in driving protein–DNA interac-tions, the physical basis of such cooperative behavior remains poorly
understood. In the present study, using isothermal titration calorimetry in
conjunction with site-directed mutagenesis, we provide evidence that an
intricate network of energetically-coupled residues within the basic regions
of the Jun-Fos heterodimeric transcription factor accounts for its allosteric
binding to DNA.

It has always fascinated me how energetic, passionate, and in some cases fanatical
people get over a topic like performance management and cost management.
Over the years I have seen discussions that could have doubled as death matches
over whether you should use a verb/noun description of an activity in an ABC
I have always tried to boil it down to something simple. To me, performance
management is optimizing your organization’s performance.
In this concise and compelling history, Cambodia’s past is described in vivid detail, from the richness of the Angkorean empire through the dark ages of the 18th and early-19th centuries, French colonialism, independence, the Vietnamese conflict, the Pol Pot regime, and its current incarnation as a troubled democracy. With energetic writing and passion for the subject, John Tully covers the full sweep of Cambodian history, explaining why this land of contrasts remains an interesting enigma to the international community.

physics by application of conducting polymers; hydrogel films on optical fiber core;
thin film polymers; PDLC films application; photopolymers for holographic media;
microwave absorption and EMI shielding behavior of nanocomposites based on
intrinsically conducting polymers and graphene and carbon nanotubes; in the area of
polymer synthesis of conducting polymers; oxidative polymerization of aniline; electro

uclear magnetic resonance spectroscopy can now be used to investigate the biochemical energetics of human tissues and organs noninvasively. The method already has increased our understanding of some muscle diseases, has provided information from muscle metabolism about whole-body functions, control, and hormonal status, has helped in the elucidation of hitherto unrecognized causes of disease, and yielded new ideas about the control of bioenergetics in vivo. Studies on the biochemistry of human brain, liver, heart, and kidney are just beginning.
Physics explains everything from the beginning to the end of any complete
description of the human body. Such a comprehensive discussion should begin
with the basic structure of matter, as explained by quantum mechanics – the
physics at small dimensions, and end with the mechanics of human motion,
the energetics of metabolism, the fluid dynamics of blood flow through vessels,
the mechanisms for speaking and hearing, and the optical imaging system
we call the eye.
Amway Corporation marked its 50th anniversary in May 2009
with a glitzy celebration at the MGM Grand on the Las Vegas
Strip. Spotlights swept across the crowd of well-dressed people
who had come from all over the world for the event. A movie theater–
sized screen splashed the Amway logo against a cobalt blue background.
Cameras fl ashed and music pulsated. The upbeat mood and excitement
inside the auditorium felt similar to the energetic vibe at a national
political convention or a religious rally....
The state of aquatic ecosystems reflects the general state of the biosphere. The situation
in the biosphere affected by anthropogenic factors was characterized as “a slow
explosion” (Fedorov 1987). The global change in the biosphere and climatic system
of the Earth is a manifestation of this “slow explosion” (World Resources
1990–1991, Izrael et al. 1992).
Ion implantation represents a particularly useful means by which to modify the
surface properties of a variety of materials. This prosaic statement, however, does not
convey the depth of basic understanding which has been developed to fully utilize the
advantages of ion implantation. The interaction of a host lattice with the energetic
beams produces metastable states and structures which cannot be achieved by other
means. However, ion implantation also requires an understanding of the fundamental
physics and chemistry that dictate the interaction of the ion beam and the target.
However, from an energetic point of view, it has been
debated that phenolics favour hydrogen atom transfer mechanisms, in which lower energies
are involved (Leopoldini et al., 2011). The radicals derived from oxygen represent the most
important class of radical species generated in living systems. However the term antioxidant
is often used to describe the scavenging activity of all reactive radicals including e.g. RNS
This module outlines the basic mechanics of elastic response | a physical phenomenon that
materials often (but do not always) exhibit. An elastic material is one that deforms immediately
upon loading, maintains a constant deformation as long as the load is held constant, and returns
immediately to its original undeformed shape when the load is removed. This module will also
introduce two essential concepts in Mechanics of Materials: stress and strain
In defining a new paradigm it is difficult to know where to begin. How do you take fifteen years
of medical practice in pathology and ten years of clinical observation utilizing the theories of
traditional Chinese medicine, acupuncture, homeopathy, and therapeutic nutrition and meld them
into a model of biological understanding and medical practice? The answer is actually quite simple
— start from the beginning and build a convincing model based upon sound physics, physiology,
pathology, and clinical medicine and see if the model fits the expected outcome.
The bird soaring upward and forward on the cover of this new edition is a swallow. Found throughout the world, swallows are joyful, playful, energetic birds whose comings and goings announce changes in the seasons.
A thermodynamic decription of a process need a well - defined system. A thermodynamic system contain everything of thermodynamic interest for a particular chemical process within a boundary.. The buondary is either a real or hypothetical enclosure or sufaces that confines the system and separates it from it's surrounding
