Comparing phreatic evaporation at zero water table depth with water surface evaporation [PDF]
Journal of Arid Land, 2018 Salt-affected soils are mostly found in irrigated areas within arid and semi-arid regions where the groundwater table is shallow. Soils of this type have become an increasingly severe problem because they threaten both the environment and the sustainable development of irrigated agriculture. A tool to estimate phreatic evaporation is therefore urgently

Advanced Engineering Materials, EarlyView.Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Preparation and analysis of testate amoebae in peatland palaeoenvironmental studies [PDF]
Mires and Peat, 2010 The use of testate amoebae in studies of peatland hydrology and palaeohydrology has been increasing, and considerable efforts have been made over the past decade to standardise techniques as much as possible.

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Prey – predator model on the interaction between the drawdown level of an aquifer and maize yield
Journal of Applied Sciences and Environmental Management, 2017 Groundwater is a major source of water for irrigation purposes and for sustainable growth of Agricultural development. In this paper we formulated a mathematical model to analyse the interaction between the Draw-down levels in an unconfined aquifer with
