Development of a recording water flow meter using ultrasonic measurement of water levels in a slotted U-pipe
(Elsevier, 2007)
The accurate measurement and recording of water flow rates is necessary in the perfor-mance of field experiments in irrigation, overland flow or drainage studies. There is a lack of reliable, low-cost commercial flow ...

Dispersion analysis of periodic structures in anisotropic media: application to liquid crystals
(IEEE Computer Society, 2022)
This paper presents an efficient method to compute the dispersion diagram of periodic and uniform structures with generic anisotropic media. The method takes advantage of the ability of full-wave commercial simulators ...

Analytical approach to soliton ratchets in asymmetric potentials
(2005)
We use soliton perturbation theory and collective coordinate ansatz to investigate the mechanism of soliton ratchets in a driven and damped asymmetric double sine-Gordon equation. We show that, at the second order of the ...

Forced nonlinear Schrödinger equation with arbitrary nonlinearity
(2012)
We consider the nonlinear Schrödinger equation (NLSE) in 1+1 dimension with scalar-scalar self-interaction g2κ+1(ψ☆ψ)κ+1 in the presence of the external forcing terms of the form re−i(kx+θ)−δψ. We find new exact solutions ...

Modelos para toma de decisiones en el litoral andaluz
(Sociedad Española de Protección Radiológica (SEPR), 2008)
Se han desarrollado tres modelos de dispersión de respuesta rápida que cubren el litoral andaluz en su totalidad para su uso en caso de emergencia tras un vertido radiactivo. Estos modelos pueden ayudar en el proceso ...

AMS measurements of 129I in seawater around Iceland and the Irminger Sea
(ScienceDirect, 2013-01)
Large amounts of iodine-129 were, and still are, released into the environment from nuclear facilities, in particular from two reprocessing facilities located on the east coast of the North Atlantic Ocean (Sellafield and ...

Kinetic reactive transport explains distinct subsurface deposition patterns of pollutants in sediments. The case of the Sellafield-derived 236U, 137Cs and 239,240Pu in the Esk Estuary, UK
(ScienceDirect, 2023-04-15)
The kinetics of the uptake of pollutants by solids in sediments interacts with transitional eddy diffusivity in the pore fluid, leading to different depth-distribution patterns. This work aims to gain insights into the ...

Implications for food safety of the uptake by tomato of 25 trace-elements from a phosphogypsum amended soil from SW Spain
(Elsevier, 2014)
Phosphogypsum (PG) has been usually applied as Ca-amendment to reclaim sodic soils such as those in the marshland area of Lebrija (SW Spain). This work aimed at the effects of PG amendments on the uptake of trace-elements ...

Transfer of Cd, Pb, Ra and U from Phosphogypsum Amended Soils to Tomato Plants
(Springer, 2009)
About 170 million tons of phosphogypsum (PG) are annually generated worldwide as a by-product of phosphoric acid factories. Agricultural uses of PG could become the main sink for this waste, which usually contains significant ...

The cumulative effect of three decades of phosphogypsum amendments in reclaimed marsh soils from SW Spain: 226Ra, 238U and Cd contents in soils and tomato fruit
(Elsevier, 2008)
Phosphogypsum (PG), a by-product of the phosphate fertiliser industries, has been applied as soil amendment to reduce Na saturation in soils, as in the reclaimed marsh area from SW Spain, where available PG has a typical ...
