Kalman filters are often used to estimate the state variables of a dynamic system. However, in application some known signal information is either ignored or dealt with heuristically. For instance, state-variable constraints (which may be based on physical considerations) neglected because they do not fit easily into structure filter. Thus, two analytical methods incorporate inequality filter now derived. The first method general technique that uses hard enforce inequalities estimates....
Nanotechnology is a much promising field of science and technology with applications in wide range areas such as electronics, biomedical applications, energy cosmetics. Metal-based engineered nanoparticles (ENPs) are common many technological applications; some the most available commercially silver, gold, copper oxide (CuO), zinc (ZnO) cadmium sulphide (CdS). The toxicity metal-based NPs may be either due to their specific physical characteristics or metals released from under environmental...
Rare earth elements (REE) are emerging contaminants due to their increased use in diverse applications including cutting-edge and green-technologies. Their environmental concerns contradicting results concerning biological effects require an extensive understanding of REE ecotoxicology. Thus, we have studied the fate, bioaccumulation three representative REE, neodymium (Nd), gadolinium (Gd) ytterbium (Yb), individually mixture, using freshwater bivalve Corbicula fluminea. The organisms were...
Since 1995, Dikerogammarus villosus Sowinski, a Ponto-Caspian amphi- pod species, has been invading most of Western Europe' s hydrosystems. D. geographic extension and quickly increasing population density enabled it to become major component macrobenthic assemblages in recipient ecosystems. The ecological characteristics on mesohabitat scale were investigated at station the Moselle River. This amphipod is able colonize wide range sub- stratum types, thus posing threat all freshwater Rivers...
Summary Ecological stoichiometry, that is, the study of mass balance multiple key chemical elements during ecological interactions, has recently been generalized to most ecosystems. Yet, effects stoichiometric constraints on life‐history traits detritivores, one important trophic level through its importance in nutrient cycling, are still poorly documented. Forested headwater streams constitute representative detritus‐based ecosystems, relying leaf litter inputs as main energy and source for...
Non-indigenous species are increasingly recognized as altering local com- munities in newly colonized areas. In some north European freshwater systems, the Ponto-Caspian invasive crustacean Dikerogammarus villosus (Amphipoda) is im- plicated to have such an effect, with general monitoring of its progress and pact required. The present study contributes this monitoring. D. was ob- served 2003 all major French rivers prospected (i.e. Rhine, Meuse, Moselle, Sao ne, Rho Seine, Loire), a region...
Abstract The latest threatening invader in European freshwaters is Dikerogammarus villosus , a large gammarid of Ponto‐Caspian origin exhibiting predatory behaviour. Its biology and population dynamics were studied over one‐year period recipient ecosystem to determine bio/ecological traits having facilitated its rapid establishment. study revealed that D. reaches sexual maturity early, at six mm length, produces three reproductive peaks, though the species reproduces all year long, hence...
Exposures in realistic environmental conditions are essential to properly assess the effects of emerging pollutants on ecosystems. While ceria nanoparticles (nCeO2) production and use expanding quickly, ecotoxicity studies remain very scarce. In this study, we set up experimental systems reproducing a simplified ecosystem chronic exposure citrate-coated nCeO2 (ci-CeO2) bare (ba-CeO2) freshwater mussel Dreissena polymorpha using an integrated multibiomarker approach. The fate was tightly...
Because of their antibacterial properties, silver (Ag) engineered nanomaterials are included in many products. The present study used a standardized Ag nanomaterial (NM-300K, 20 nm) supplied with stabilizing agent. aim was to investigate the behavior an estuarine-like medium at 2 salinities (15 psu and 30 psu). Uptake as well sublethal effects (10 μg Ag/L), its agent, AgNO3 Ag/L) were assessed clam Scrobicularia plana, after 7 d exposure. release soluble from experimental media quantified by...
This study provides a comparative analysis of the National Pension System (NPS) and Unified Scheme (UPS) from perspective government employees in India. The research evaluates financial fiscal implications transitioning between these two pension models. While NPS, introduced 2004, emphasizes market-linked contributions to alleviate pressure, it is perceived as riskier due its dependence on investment returns. In contrast, UPS, which offers defined benefit scheme, ensures guaranteed...
Climate change, compounding with non-climatic stressors, threatens the human habitability of Earth’s environments. The complex interplay multiple drivers increases uncertainty, challenging stakeholders to make long-term decisions. Enhancing decision-makers' knowledge and awareness is key navigating this uncertainty developing effective adaptive strategies. While has been recently recognised as an important condition in adaptation studies, its definition conceptualisation are still...
Abstract : A key to producing reliable engine diagnostics and prognostics resides in the fusion of different processing techniques. Fusion techniques has been shown improve diagnostic performance while simultaneously reducing false alarms. Presented here is an approach that fuses a physical model called STORM (Self Tuning Onboard, Real-time Model) developed by Pratt & Whitney, with empirical neural net provide unique hybrid enhanced (eSTORM) for diagnostics. piecewise linear approximation...
Amphipods are recognised as an important component of freshwater ecosystems and frequently used ecotoxicological test species. Despite this double interest, there is still a lack information concerning toxic impacts on ecologically relevant behaviours. The present study investigated the influence cadmium (Cd), non-essential heavy metal, both antipredator behaviours antitoxic responses in invasive amphipod Dikerogammarus villosus under laboratory conditions. Amphipod behaviour (i.e. refuge...
Summary 1. Dam presence is commonly associated with strong accumulation of polluted sediments. In spite this context multiple stressors, physical effects are often solely considered in the ecological assessment dam impacts. 2. We studied four ‘reservoir/downstream reach’ systems differing levels sediment contamination reservoirs. Using assemblages and biotrait (i.e. or biological attribute) responses macroinvertebrate communities leaf litter breakdown, we examined individual potential...
