Transforming Agricultural Water Management Through the Water–Energy–Food Nexus: Trends, Opportunities, Barriers and Solutions

Irrigation and Drainage, EarlyView.
ABSTRACT Agricultural water management (AWM) is increasingly transitioning towards transformative thinking, where interconnected sectors, including water, energy and food, are managed holistically. Trends point towards cross‐sectoral and harmonised strategies to optimise water use efficiency and productivity, integrate renewable energy, promote ...

Spherical Harmonics Expansion of the Vlasov-Poisson initial bounary value problem

, 2005
We derive and analyze the ‘SHE' (Spherical Harmonics Expansion) type system of equations coupled in energy. We also show that diffusive behavior occurs on long time and distance scales and we determine the diffusion tensor. The analysis is based on

Optimizing rapeseed protein purification: a continuous chromatographic approach for napin and cruciferin

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Napin and cruciferin, the predominant storage proteins in Brassica napus (rapeseed), exhibit favorable techno‐functional properties such as emulsification and gel formation, positioning them as promising candidates for the encapsulation and delivery of bioactive compounds. Their classification as GRAS (Generally Recognized As Safe),

Intrahour Direct Normal Irradiance Forecasting Based on Sky Image Processing and Time-Series Analysis

SolarPACES Conference Proceedings
The present paper exhibits a hybrid model for intrahour forecasting of direct normal irradiance (DNI). It combines a knowledge-based model, which is used for clear-sky DNI forecasting from DNI measurements, with a machine-learning-based model, that ...

Method Based on Continuous Artificial Dry and Humid UV Treatments to Reduce the Luminescence Background in the Raman Spectra of Plastics

Journal of Raman Spectroscopy, EarlyView.
We propose an UV photobleaching pretreatment to reduce the strong luminescence in the Raman spectra of plastic samples. Our protocol proves its efficiency whatever the luminescence origin (from the pigments or from a surface biofilm) but requires a careful optimization of the illumination conditions (UV wavelength, time, humidity) to reach the ...

Contrasted habitat selection among Eurasian curlew populations according to landscape heterogeneity and breeding stage

The Journal of Wildlife Management, EarlyView.
This study aimed to quantify the spatio‐temporal use of breeding environments by the Eurasian curlew in 5 contrasting agricultural landscapes. To this end, 64 individuals were tagged with GPS devices to assess their space use according to their breeding stages and define their foraging habitat selection.
