Abstract:
Wildlife and humans are exposed to a complex mixture of endocrine active chemicals. The activity of a specific chemical in any mixture can be modified through interactions with other components of the mixture. The toxic equivalency factor (TEF) approach for risk assessment was developed for chemicals such as halogenated aromatics that induce their effects through ligand-activated receptors. For persistent halogenated aromatic AhR agonists, this approach has some utility. However, the use of the TEF approach for endocrine active compounds is confounded by the unique tissue- and response-specifi

Abstract:
The morphology of a mixture made of a polar active gel immersed in an isotropic passive fluid is studied numerically. Lattice Boltzmann method is adopted to solve the Navier–Stokes equation and coupled to a finite-difference scheme used to integrate the dynamic equations of the concentration and of the polarization of the active component. By varying the relative amounts of the mixture phases, different structures can be observed. In the contractile case, at moderate values of activity, elongated structures are formed when the active component is less abundant, while a dynamic emulsion of pass

In the case of simple vapour mixtures adsorbed by active carbons, the activity coefficients seem to depend essentially on the composition of the adsorbed phase, rather than on the degree of micropore filling. Consequently, the liquid–solid adsorption equilibrium of benzene + 1,2-dichloroethane mixtures has been investigated at 293 K, using a typical active carbon and following earlier work for adsorption from the vapour phase. This system has the advantage that the mixture is ideal in the liquid state, which provides a convenient reference for the study of the adsorbed phase. The activity coef

Pesticide resistance poses a critical threat to agriculture, human health and biodiversity. Mixtures of fungicides are recommended and widely used in resistance management strategies. However, the components of the efficiency of such mixtures remain unclear. We performed an experimental evolutionary study on the fungal pathogen Z. tritici to determine how mixtures managed resistance. We compared the effect of the continuous use of single active ingredients to that of mixtures, at the minimal dose providing full control of the disease, which we refer to as the “efficient” dose.

Abstract Corrosion in process industries often occurs in mixtures of various acids and salts. Such corrosion behavior cannot be predicted simply by extrapolation from the behavior in pure acids. For example, corrosion behavior in wet process phosphoric acid is significantly different from that in pure orthophosphoric acid due to a variety of impurities in the former. Corrosion behavior in sulfuric and hydrofluoric acid mixtures is quite different from that in either of the pure acids.

The corrosion tests show that this alloy can be used for heat-exchangers to recover waste heat at low temperatures in fossil fuel-fired power plants. This new alloy, which is composed of 20% chromium, 20% molybdenum, 2% tantalum and balance nickel, shows excellent corrosion resistance to sulfur dewpoint corrosion. The general and localized corrosion resistance behavior of this new alloy has been tested in different candidate solutions such as sulfuric acid so

Abstract:
Abstract Discrete embedded zinc anodes have been proposed to extend the service life of concrete patch repair by providing localized cathodic protection to adjacent steel. The performance of such anodes must be enhanced by chemical agents, which maintain the zinc in an electrochemically active state and increase the flow of protective current to the steel. In this study, the effects of various chemical agents were studied by monitoring both the flow of current and steel polarization on laboratory test blocks. Protective current for test blocks containing zinc anodes and lithium-based activatin

Abstract:
Abstract Barium sulfate scale deposits are serious impediments in the gas and oil production industry, as they are tenaciously adhering on surfaces and they are hard to remove due to the independence of their solubility on pH. The practice most commonly applied is prevention of their formation using water soluble compounds acting as inhibitors which block active crystal growth sites. Blocking efficiency depends to a large extent on their molecular structure. In the present work we report on the kinetics of nucleation and crystal growth of Barium Sulfate from aqueous supersaturated solutions us

Abstract:
Abstract The objective of the present study is to evaluate the corrosion properties of carbon steel in MDEA / H2O / CO2 / O2 / HSSs mixtures related to the CO2 capture process in fossil fuel-fired power plants. Short-term and long-term corrosion tests were performed in 50 wt.% methyldiethanolamine (MDEA) solutions at 50°C under atmospheric pressure with different combinations of CO2, O2 and HSSs (bicine, formate, sulfate). Corrosion behavior of carbon steel was evaluated by using electrochemical methods (LPR, EIS and cyclic polarization), weight loss measurements, and surface analytical techni

Abstract:
Induced Systemic Resistance (ISR) is a highly variable property that can be induced by compost amendment of potting media and soils. For example, previous studies showed that only 1 of 79 potting mixes prepared with different batches of mature composts produced from several different types of solid wastes were able to suppress the severity of bacterial leaf spot of radish caused by Xanthomonas campestris pv. armoraciae compared with disease on plants produced in a nonamended sphagnum peat mix. In this project, microbial consortia in the rhizosphere of plants grown in ISR-active compost-amended

Abstract:
To assist US Army Corps of Engineers resource managers in monitoring for cyanobacteria bloom events, a laboratory method using hyperspectral imaging has been developed. This method enables the rapid detection of cyanobacteria in large volumes and has the potential to be transitioned to aerial platforms for field deployment. Prior to field data collection, validation of the technology in the laboratory using monocultures was needed. This report describes the development of the detection method using hyperspectral imaging and the stability/reliability of these signatures for identification purpo

Abstract:
This project was based on the hypothesis that nematodes interacting with plants as either parasites or beneficial saprophytes are attracted to their host by natural products. This concept was supported by numerous observations that parasitic nematodes are attracted to root exudates. Our overall goal was to identify nematode sensory compounds from root exudates and to use that information for reducing nematicide applications. We applied skills of the investigators to achieve three specific objectives: 1) Identify nematode behavioral cues (e.g., attractants or repellents) in root exudates; 2) Id

Abstract:
The Montney Formation in Alberta and British Columbia, Canada is an early Triassic siltstone currently in an active diagenetic environment at depths greater than 1,000 m, but with maximum burial depths potentially exceeding 5,000 m (Ness, 2001). It has undergone multiple phases of burial and uplift and there is strong evidence for multiple generations of hydrocarbon maturation/migration. Understanding the origin and history of diagenetic fluids within these systems helps to unravel the chemical changes that have occurred since deposition.

In the process, approximately 300 rural girls have participated in a life-transforming chance to learn, play, and grow into productive members of their local communities. Currently other villages—and soon other governorates—are joining the Ishraq network. Ishraq is a mixture of literacy, life-skills training, and—for girls who have been sheltered in domestic situations of poverty and isolation—a chance to play sports and games with other girls their age and

Abstract:
Tire rubber waste (TRW) is a complex mixture of materials, such as rubbers, steel, textile fibers, carbon black, and other additives. Its polluting capacity is a severe environmental problem, especially in landfills and waste management processes. As a practical solution to mitigate TRW’s environmental impact, thermoplastic elastomers (TPE) commonly reuse the ground tire rubber (GTR). This work presents an in-situ devulcanization of ground tire rubber (DGTR) and re-vulcanization of devulcanized ground tire rubber using dicumyl peroxide (DCP) and waste ethylene-vinyl-acetate (wEVA).
