Journal of Fish Biology, EarlyView.Abstract Sex is an important driver of variation in behaviour, ecology and physiology. Sex identification in the Critically Endangered European eel (Anguilla anguilla) currently requires fish sacrifice, or the use of morphological differences such as body length, which can be inaccurate in certain habitats and at intermediate body lengths.

The significance of flotation froth appearance for machine vision control
, 1996 The development of robust automatic control systems has proved difficult because of the complexity of the problem. Flotation is notorious for its susceptibility to process upsets and consequently its poor performance, making successful flotation control ...

FieldDino: Rapid In‐Field Stomatal Anatomy and Physiology Phenotyping
Plant, Cell &Environment, EarlyView.ABSTRACT Stomatal anatomy and physiology define CO2 availability for photosynthesis and regulate plant water use. Despite being key drivers of yield and dynamic responsiveness to abiotic stresses, conventional measurement techniques of stomatal traits are laborious and slow, limiting adoption in plant breeding.

Fine coal beneficiation by pilot column flotation [PDF]
Journal of Mining and Metallurgy. Section A: Mining, 2018 Beneficiation of coal fines with high ash content was attempted in an operating coal preparation plant by retrofitting a 0.5 m diameter pilot plant scale flotation column in the circuit. The collector and frother dosage were optimized as 0.680 kg/t and 0.

Microplastic Dynamics in Sediment Layers of Two Ramsar‐Designated Wetlands
Water and Environment Journal, EarlyView.ABSTRACT Little is known about the vertical and spatial dynamics of microplastics in relation to hydrology and land use, particularly in African context. This study aimed to assess the abundance, type, colour and vertical distribution of microplastics in sediment from two Ramsar‐designated wetlands, the Makuleke and Nylsvley. Sediment core samples were

A study of flotation froth phase behaviour
, 2015 The performance of the froth phase, usually evaluated as froth recovery determines overall flotation performance. In most flotation operations, recovery across the froth is rate controlling; consequently understanding the froth phase is very critical ...

Effect of froth stability on dewatering of coal flotation concentrates
, 2015 This study was conducted to investigate the effect of froth stability on coal filtration and dewatering characteristics by comparing the filtration and dewatering responses of flotation concentrates and unfloated coal slurries. The results show that high
