  • 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 collaboration.

  • 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.

  • 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 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 E.g....

  • 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.

  • 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.
