Tritium Modelling in Aquatic Systems
نویسندگان
چکیده
Models commonly used in tritium dose assessment are steady state specificactivity models based on the assumption of complete isotopic mixing with the stable element, and isotopic equilibrium between all environmental compartments (IAEA, 2010). These models may not be adapted to situations with fluctuating tritium levels in rivers, resulting from discontinuous radioactive discharges or accidental release. To take into account these variations in radioactive discharges, dynamic river, lakes and coastal waters models have been developed (IAEA 2008a, SisBAHIA®, TELEMAC (ref), Mascaret (ref), RIVTOX (Zheleznyak et al., 2000), POSEIDON (Heling et al., 2000)) supplemented by time-dependent food chain models (Ciffroy et al 2005; Galeriu et al 2005; Melintescu and Galeriu, 2011).

Photocatalytic Reduction of Ni (II) Ions Using Low Amounts of Titania Nanoparticles: RSM Modelling, Kinetic
Background: Heavy metals in aquatic systems usually interfere with many beneficial uses of water. Divalent nickel is a commonly occurring toxic metal in natural ecosystems due to the effluent of refineries, electroplating, and casting industries. In aquatic environments, nickel appears as Ni (II) and Ni0. Despite the high reported toxicity for Ni (II), Ni0 is only slightly toxic. Various meth...

This systematic review considers how water quality and aquatic ecology models represent the phosphorus cycle. Although the focus is on phosphorus, many of the observations and discussion points here relate to aquatic ecosystem models in general. The review considers how models compare across domains of application, the degree to which current models are fit for purpose, how to choose between mu...

This study aims to examine the ability of free floating aquatic plants to remove phosphorus and to predict the reduction of phosphorus from rice mill wastewater using soft computing techniques. A mesocosm study was conducted at the mill premises under normal conditions, and reliable results were obtained. Four aquatic plants, namely water hyacinth, water lettuce, salvinia, and duckweed were use...

Several approaches have been introduced in literature for active noise control (ANC)systems. Since Filtered-x-Least Mean Square (FxLMS) algorithm appears to be the best choice as acontroller filter. Researchers tend to improve performance of ANC systems by enhancing andmodifying this algorithm. This paper proposes a new version of FxLMS algorithm. In many ANCapplications an online secondary pat...
