Contaminated Aquatic Sediments [PDF]

Water Environment Research, 2007
A review of the literature published in 2014 relating to the assessment, evaluation and remediation of contaminated aquatic sediments is presented. The review is divided into the following sections: policy and guidance, methodology, distribution, fate and transport, bioavailability, bioaccumulation, risk, toxicity and remediation.

In vitro studies to characterise different physico-chemical properties of some feed grains and their impact in monogastric nutrition

Italian Journal of Animal Science, 2021
Characterisation of the variations in physico-chemical properties of grains may help to improve the feeding value of grains for animal nutrition. Thus, this study aimed to obtain more extensive quantitative ideas concerning different physico-chemical ...

The effect of $^{22}$Ne diffusion in the evolution and pulsational properties of white dwarfs with solar metallicity progenitors [PDF]

, 2016
Because of the large neutron excess of $^{22}$Ne, this isotope rapidly sediments in the interior of the white dwarfs. This process releases an additional amount of energy, thus delaying the cooling times of the white dwarf.

Combining transient dynamics and logistic‐asymptotic growth to study the recovery of two seabird populations after rat eradication

Population Ecology, EarlyView.
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

The Effect of Helium Sedimentation on Galaxy Cluster Masses and Scaling Relations

, 2011
Recent theoretical studies predict that the inner regions of galaxy clusters may have an enhanced helium abundance due to sedimentation over the cluster lifetime.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

Population Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Mechanical and toxicological effects of deep-sea mining sediment plumes on a habitat-forming cold-water octocoral

Frontiers in Marine Science, 2022
Deep-sea mining activities are expected to impact deep-sea biota through the generation of sediment plumes that disperse across vast areas of the ocean. Benthic sessile suspension-feeding fauna, such as cold-water corals, may be particularly susceptible ...

Numerical and experimental analysis of the sedimentation of spherical colloidal suspensions under centrifugal force

, 2018
Understanding the sedimentation behaviour of colloidal suspensions is crucial in determining their stability. Since sedimentation rates are often very slow, centrifugation is used to expedite sedimentation experiments.

Faunal response to benthic and hyporheic sedimentation varies with direction of vertical hydrological exchange [PDF]

, 2014
1. Sedimentation and clogging of benthic and hyporheic zone substrates is increasingly being recognised as one of the greatest threats to the ecological integrity of riverine ecosystems globally. This ex-situ study examined the influence of sedimentation
