Cyclic-nucleotide-specific phosphodiesterases (PDEs) are key players in the
intracellular signaling pathways of the important human pathogen Trypano-soma cruzi. We report herein the identification of an unusual PDE from
this protozoal organism. This enzyme, TcrPDEC, is a member of the class
I PDEs, as determined from the presence of a characteristic signature
sequence and from the conservation of a number of functionally important
amino acid residues within its catalytic domain.
For the first time, the detection of DNA sequences, related to HIV (found in AIDS patients), using Methylene Blue (MB) as the redox indicator was performed. The voltametric signals have been investigated on bared chitosan (CS) modified; probe immobilized (DNA single strand) and target-hybridized (DNA double strand) electrodes sequentially by means of Cyclic Voltammetry (CV) and Square Wave Voltammetry (SWV). The response of hybridization between the probe and perfectly complementary, double-base mismatch, single-base mismatch of analyzed targets were clearly identified.
This is a dangerous combination. The persistence and mobility of POPs means that they
are literally everywhere in the world, even in the Arctic,Antarctica, and remote Pacific islands.
Their attraction to fatty tissue, known as "bioaccumulation", means that even though a
poison is first dispersed widely and thinly it gradually starts to concentrate as organisms
consume other organisms as they move up the food chain.
We have built a “production” system and an advanced research prototype. The production
system uses the commercial Java Message Service (SonicMQ) and has been used very
successfully to build a synchronous collaboration environment applied to distance education.
The publish/subscribe mechanism is powerful but this comes at some performance cost
and so it is important that it satisﬁes the reasonably stringent constraints of synchronous
While Nesjar created the sculpture on the green in front of The Art
Museum, he conducted a unique, outdoor seminar. The process
involved building wooden forms to establish the basic shapes of the
columnar pedestal and then a similar structure for the head itself. After
completion of the wooden form, a mixture of crushed stone (imported
from Norway) and iron tie-rods was packed within, and liquid concrete
was injected under pressure from the base up. Nesjar later sandblasted
the outer skin to expose the colorful aggregate.
Controlled oxidation is increasingly being practiced using solid peroxides, pH
modifiers, and catalysts that promote the generation of free radicals. This new
approach moderates the rate of dissolution and peroxide generation, which in turn
controls that rate of reaction between peroxide and the petroleum contaminants.
The use of slurried peroxides creates the opportunity to release oxidants and
oxygen over a longer period, which can promote subsequent aerobic remediation.
The sensory networks that transduce information starting with the capture of a photon into
a suite of downstream responses are well known. Historically these pigments were
postulated to control various aspects of plant growth and development, particularly
germination, phototropic movements and the transition between vegetative and
reproductive growth. Long before the genes and proteins were identified and characterized,
a tremendous body of work produced evidence of their activities and effects on physiology.
Light quality effects on germination were examined by Lewis H.
The impact of human activities on the environment – and on climate change in particular – are issues
of growing concern confronting life on Earth. At the same time, information and communication
technologies (ICTs) are being rapidly deployed around the world. Although ICTs require energy
resources, they also offer a number of opportunities to advance global environmental research,
planning and action. This includes monitoring and protecting the environment as well as mitigation of
and adaptation to climate change.
The manufacturing sector has always had strong linkages with the agricultural sector, with agriculture sourcing from it over half of intermediate goods, such as insecticides, stock feeds, and fertilizer, while nearly half of agricultural produce is supplied to the manufacturing sector. The performance of the two sectors has historically been closely correlated. The collapse of agricultural activities associated with the implementation of the fast track land reform program by the Government had a devastating impact on the manufacturing sector in the past decade.
Internal Rate of Return (IRR) is the discount rate at which the Present
Value of future cash flows equals the initial capital invested (i.e. the discount rate at which the
Net Present Value of a series of cash flows equals 0) expressed as a percentage.
An IRR less than your targeted rate of return suggests you are paying too much for the property
to get your targeted rate of return
An IRR greater than your target rate of return suggests you could pay more for the property and
still get your targeted rate of return
Central to these conditions are developments
in benchmark interest rates. These comprise
mainly the key ECB interest rates, money
market rates and government bond yields,
with the latter containing the term structure of
risk-free rates, domestic sovereign credit risk
and liquidity premia (see Chart 1). These rates
are the main determinants of the conditions of
direct ﬁ nancing in ﬁ nancial markets for both
non-ﬁ nancial and ﬁ nancial corporations and,
consequently, for the wholesale market funding
and deposit funding of banks.
The potential impact of debt on inflation depends on the response of monetary policy. High
government debt could well constrain the ability of the central banks to set the policy rate to
control inflation. This is the “fiscal dominance” view. Heavily debted governments force the
central bank to accept inflation in order to reduce the real value of their debt. Historically,
inflation has helped governments to reduce their public debt burdens.
Panel C of Table 5 describes the board’s audit committee for our restating
and control samples. With the exception of one restating firm (Oil-Dry Company),
each firm in both our samples has an audit committee. In many
respects, the structure of this committee is similar for the two groups of
firms. The median size of this committee is three members in each group.
The mean (median) proportion of independent directors on this committee
(PIDAUD) is about 94 percent (100 percent) in both groups. But there is
one striking difference between the two groups.
Scope of decision-making: Amajor factor is the scale at which query processing and viewmaterialization decisions
are made. At one extreme, all queries in the entire system are optimized together, using complete knowledge of the
available materialized views, resources, and network bandwidth constraints — this poses all of the challenges of
multi-query optimization plus a number of additional difﬁculties. In particular, work must be distributed globally
across many peers, and decisions must be made about when and where to materialize results for future use.
Building engineering physics is a relatively new scientific discipline which
investigates the areas of natural science that relate to the performance of
buildings and their indoor and outdoor environments. The field deals
principally with the flows of energy, both natural and artificial, within and
Banks’ main vulnerabilities are their exposure to highly indebted households through
residential mortgage lending, together with their sizable short-term offshore borrowing.
Household debt is high at about 150 percent of disposable income but is held mainly by
higher income households. Moreover, exposure to high-risk mortgages is small.
Note that the above list does not include installment premiums. This is because the decision to
use installments versus an up-front premium is often a function of the billing system and does
not affect written premium. In the U.S., the total of all known future installment premiums is
generally booked up front as written premiums. Installments due but not yet collected are
categorized in one premium receivable account, while those to-be-billed in the future and not yet
due are in another premium receivable account.
The above items may apply to either direct...
Lead is the most pervasive pollutant found in the Blacksmith Institute’s database and is a well-documented
health hazard. The Blacksmith Institute has identified over 500 sites polluted by lead, putting an estimated
16 million people at risk. Based on the Blacksmith Institute’s investigations, the top sources contributing
to lead pollution, by population, are lead smelting, mining and ore processing, industrial estates and
lead-acid battery recycling and manufacturing.
