Fourier transform infrared (FTIR) studies showed the changes in a relative intensity of stretching vibrations of the PANI and PANI-Ni films, in a band of 1480 and 1590 cm-1 , as well as those in a band of 1200 and 1350 cm-1 , and evidenced the conversion of quinoid form of PANI to bipolaron structure, and finally to the more delocalized polaronic sites during protonation. This also shows that nickel-nanoclusters play a role as a source supplying protons to promote the protonation, giving a change in population of quinoid and aromatic forms of PANI, and increasing a number of NH bond.
Eckhart Tolle is emerging as one of today's most inspiring teachers. In The Power of Now , already a word-of-mouth bestseller in Canada, the author describes his transition from despair to self-realization soon after his 29th birthday. Tolle took another ten years to understand this transformation, during which time he evolved a philosophy that has parallels in Buddhism, relaxation techniques, and meditation theory but is also eminently practical.
This book, based on intensive research I have conducted since the late 1970s,
is my attempt to cover in one monograph the modern theory of surface generation
with a focus on kinematic geometry of surfacemachining on amultiaxis
numerical control (NC) machine. Although the orientation of this book
is toward computer-aided design (CAD) and computer-aidedmanufacturing
(CAM), it is also useful for solving problems that relate to the generation of
surfaces on machine tools of conventional design (for example, gear generators,
and so forth)....
The idea of using ultrasonic waves in medical and engineering fields came from
military applications of sound waves in sonar systems. Sokolov, Firestone, Simons,
and several other researchers are among the ones who studied this high frequency
kind of wave in the first half of twentieth century.
Ultrasonic waves are defined as those with frequencies higher than 20 kHz. The
constant development of data acquisition systems and probes seems to work,
removing the upper limit of the wave frequency that can be acquired.
The first is Faraday’s law of induction, the second is Amp`ere’s law as amended by
Maxwell to include the displacement current ∂D/∂t, the third and fourth are Gauss’ laws
for the electric and magnetic fields.
The displacement current term ∂D/∂t in Amp`ere’s law is essential in predicting the
existence of propagating electromagnetic waves. Its role in establishing charge conservation
is discussed in Sec. 1.7.
Eqs. (1.1.1) are in SI units.

Globally, clinker is typically produced in rotary kilns. Rotary kilns can be either wet
process or dry process kilns. Wet process rotary kilns are more energy-intensive and have
been rapidly phased out over the past few decades in almost all industrialized countries
except the US and the former Soviet Union.
The contribution of inorganic fertilizer to surface water N
contamination increased after 1960 as the widespread and
intensive use of inorganic N fertilizers rapidly
The use of N fertilizer has allowed greater
production of feed and food crops per unit area cultivated.
In the United States, 75% of N fertilizer is applied to
maize, while in other countries, N fertilizer is primarily
used on wheat and rice.
Hydrogenation is one of the most intensively studied fields of metal complex catalyzed homogeneous transformations. There are several reasons for such a strong interest in this reaction. First of all, there are numerous important compounds which can be produced through hydrogenation, such as pharmaceuticals, herbicides, flavors, fragrances, etc [1-3]. Activation of is involved in other important industrial processes, such as hydroformylation, therefore the mechanistic conclusions drawn from hydrogenation studies can be relevant in those fields, as well.
At the same time, high tech professionals often perceive work as a “serious game” (Strannegård & Friberg,
2001), and not drudgery: they involve in playful behaviors at work (Hunter, Jemielniak, & Postuła, 2010).
Software engineers often participate in non-paid, open collaboration production (Lakhani & Von Hippel, 2003).
Modes of collaboration established in virtual and high-tech communities are similarly transforming
workplace relations in the brick-and-mortar organizations (Benkler, 2006).
Since the 1980s, the food and beverage industry has made children and adolescents the targets
of intense and specialized food marketing and advertising efforts. The proliferation of
electronic media, the deregulation of and declining support for public service advertising, and
the booming economy of the 1990s all contributed to the transformation of children into a
consumer group (Packaged Facts, 2000). In addition, the overabundance of certain foods in the
U.S. food supply (such as corn and grains) along with decreased food production costs, allows
The statistical analysis of multivariate data requires a variety of techniques
that are entirely different from the analysis of one-dimensional data. The study
of the joint distribution of many variables in high dimensions involves matrix
techniques that are not part of standard curricula. The same is true for transformations
and computer-intensive techniques, such as projection pursuit.
Given the strong leadership evidenced by the current Governors of New York and New Jersey,
and their appropriate and intense focus on responsible government, increased transparency,
organizational efficiency and fiscal responsibility, the Port Authority now has a window of
opportunity to drive the transformational changes fundamental to addressing the challenges of
The crisis can, however, magnify the competitive advantage of research-intense firms who seize
the opportunity to reinforce market leadership through increased spending on innovation and R&D.
Many of today’s leading firms such as Microsoft or Nokia were born or transformed in the “creative
destruction” of economic downturns. And several of today's leading technology firms such as
Samsung Electronics, or Google strongly increased their R&D expenditures during and after the “new
economy” bust of 2001. ...
Solving the system of equations describing the stationary operation of a two-mode random microlaser we have found the transformation of saturated values of mode intensity when laser parameters as gain and loss coefficients as well as field coupling, photon hopping coefficients vary. From obtained results we determined which parameter takes the most important role for stationary operation of random microlasers.
Practically speaking, because buildings are
made from a series of parts, their assembly relies on
techniques of aggregating and manipulating two
dimensional materials. Computer fabrication has
opened a realm for architects to perceptually heighten
and make visible the nature of this accretion through
constructed repetition and difference.
Wild birds have taken much of the blame for the spread of H5N1 across the world
but this report by Compassion in World Farming unveils evidence showing that the
development of highly pathogenic strains of bird flu lies at the door of factory
The past two decades have seen a complete transformation in the poultry industry
with a 300% increase in production across the world. This increase is, by and large,
thanks to reliance on intensive farms and a transnational production system. Poultry
production is now a global affair.
