The structure of palladium(II) ethylenediaminetetraacetate (edta) in aqueous solutions and its adsorption on the surface of goethite (alpha-FeOOH) were studied using extended X-ray absorption fine structure spectroscopy and attenuated total reflection Fourier transform infrared spectroscopy. The obtained results show that in aqueous solutions, Pd-edta exists as a 1:1 complex, [P(edta)](2-), with e

Barnase folds cooperatively via an intermediate, followed by a rate-limiting transition state. We have probed possible movements of the intermediate and transition state on the energy landscape with changing temperature, from the temperature dependence of -values. These measure interaction energies at the level of individual residues. The results suggest that single destabilizing mutations can red

Rat adipocyte cGMP-inhibited cAMP phosphodiesterase (cGI-PDE) appears to be dually regulated in intact cells by serine phosphorylations induced by isoprenaline and insulin, respectively (Degerman, E., Smith, C. J., Tornqvist, H., Vasta, V., Belfrage, P., and Manganiello, V. C. (1990) Proc. Natl. Acad. Sci. U.S.A. 87, 533-537; Smith, C. J., Vasta, V., Degerman, E., Belfrage, P., and Manganiello, V.

BACKGROUND: The objective of this paper is to illustrate the effect of a gap of 5 mm, an overlap of 5 mm and a perfect match on the dose distribution across the junction of tangential breast fields and adjacent supraclavicular and axillary fields. MATERIALS AND METHODS: For this purpose film dosimetry was applied to measure relative dose distributions in two sagittal planes in an anthropomorphic b

Nitrogen (N) is often considered to be the major factor limiting tree growth in northern forest ecosystems. An increased N availability, however, increases the demand for other nutrients such as base cations and phosphorous (P) which in turn may change which nutrient is the limiting factor. If P or base cations become limiting, N will start to leach which means a risk of increased eutrophication o

RATIONALE AND OBJECTIVES. During coronary arteriography the blood is replaced for a short period of time with a contrast medium (CM) solution. The CM may cause a risk of arrhythmias and ventricular fibrillation (VF). Previous investigations have shown that the addition of small amounts of sodium (10-30 mmol/L) to nonionic CM may decrease the risk of VF from these media. Calcium addition to nonioni

A polyether containing Lewis acidic boron atoms in its branched chain architecture was synthesised by a condensation reaction of boron trioxide, triethylene glycol monomethyl ether and poly(ethylene glycol), the latter having a molecular weight of 300 g/mol. Electrolytes based on this polymer and several different alkali metal salts were prepared and investigated. The state of the ions in the elec

This paper investigates the effect of chlorine and silver ion solutions on the survival of Bacillus cereus (vegetative phase) and Staphylococcus aureus in batch cultures, representing dishwater. Dishwater contains organic matter and bacteria and bacterial activities are partly reduced by high pH (11-12) and temperature (55-65 degrees C) in professional and domestic dishwashers. in manual dishwashi

Recently, new cycles for power generation, such as wet cycles and cycles for CO₂ capture, have gained increasing interest. These new cycles use some sort of dilution in the air/fuel mixture, e.g. steam or CO₂. Gas turbine cycles using LCV gases can also be said to fit this description. Almost all modern gas turbines use a lean premixed combustion system, since it combines low

A major issue in Irish economic history is the lack of historical national accounts before the interwar period. This paper addresses the gap with new annual estimates of real GDP between 1842 and 1913 using an indirect estimation technique based on a set of macroeconomic variables and a dynamic factor model. Three major results emerge from the data. First, per capita growth was faster in this peri

Purpose – There is growing concern about the performance of public organizations (POs) in developing countries. Despite the fact that the advantages of innovation and learning orientation to organizations have been evidently documented in Western economies and private owned enterprises, there has been little research into these practices and their impact on enhancing competitive advantages in POs

European populations of the white-tailed eagle Haliaeetus albicilla suffered a drastic decline during the 20th century. In many countries, only a few dozen breeding pairs survived or the species disappeared completely. By today, the populations have recovered, naturally or through restocking (e.g. in Scotland or the Czech Republic). In the Carpathian Basin, which is now a stronghold in southern Eu

Diffusion phenomena through the gas diffusion layer (GDL) at the microscale are one of the most complex physical phenomena to be described in proton exchange fuel cell (PEFC) numerical models. Predicting transport parameter behavior in GDLs is a valuable stage to propose micro-architectural designs, which can improve the efficiency and performance of fuel cells (FCs). The purpose of this paper is

Mercury (Hg) is known to induce adverse immune reactions in sensitive individuals. e.g. selected inbred animal strains. Such reactions involve oral tissues and may reflect immune phenomena, that may also occur in some human oral diseases. Administration of low doses of HgCl₂ to the genetically Hg-sensitive BN rats results in the development of a syndrome with autoimmune features [BN(Hg
