Irrigation Restriction and Biomass Market Interactions: The Case of the Alluvial Aquifer [PDF]

open access: yes
The U.S. Geological Survey has determined that irrigation in Arkansas’ Delta is unsustainable. This study examines how irrigation restrictions would affect county net returns to crop production.

Water Infiltration and Redistribution in Soil Aggregate Packings

open access: yesVadose Zone Journal, 2009
Aggregation of soil particles is crucial for water flow in the vadose zone. Recent studies demonstrated that the unsaturated water flow through an aggregate pair is controlled by the contacts between aggregates. In these studies, the hydraulic conductivity of an aggregate pair was calculated as the harmonic mean of the conductivities of one aggregate ...

Hydrogen‐Bond‐Rich Supramolecular Multiblock Copolymers Facilitate Rapid Zn2+ Migration in Quasi‐Solid‐State Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The disordered growth of dendrites, corrosion, parasitic side reactions, slow de‐solvation kinetics, and inherent safety risks significantly hinder the practical deployment of conventional liquid electrolyte zinc‐ion batteries. In contrast, the novel PU‐EG+DMPA‐Zn polyurethane quasi‐solid‐state electrolyte, enriched with abundant polar functional ...

Simulation of the influence of rainfall redistribution in spruce and beech forest on the leaching of Al and SO4 2- from forest soils

open access: yesJournal of Hydrology and Hydromechanics, 2013
The aim of this study was to assess the impact of different vegetation on the distribution of rainfall (due to throughfall and stemflow), water regime, and Al and SO4 2- leaching from forest soils.

Nonlocal theory of area-varying waves on axisymmetric vortex tubes [PDF]

open access: yes, 1994
Area and axial flow variations on rectilinear vortex tubes are considered. The state of the flow is characterized by two dependent variables, a core area, and an azimuthal circulation per unit length, which vary in time and in distance along the length ...

Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.

Efficiency and equity considerations in pricing and allocating irrigation water [PDF]

open access: yes
Economic efficiency has to do with how much wealth a given resource base can generate. Equity has to do with how that wealth is to be distributed in society. Economic efficiency gets far more attention, in part because equity considerations involve value

Full‐Spectrum Solar Harvesting and Desalination Enabled by Supra‐Nano Amorphous Ruthenium Dioxide – Mineral Composites

open access: yesAdvanced Functional Materials, EarlyView.
A mineral‐based supra‐nano amorphous ruthenium dioxide composite (a‐Ru0.5‐AM) was designed, achieving 97% broadband solar absorption. Under one sun, it reaches 87.91 ± 0.32 °C with a distinct thermal buffering effect that favors thermal confinement.

Menakar Konstitusionalitas Kebijakan Redistribusi Tanah untuk Lahan Pertanian dalam UU No. 19 Tahun 2013

open access: yesVolksgeist, 2018
Land redistribution is government policy to implement Article 33 Paragraph (3) of the 1945 Constitution, where the people is the holders of authority over the earth, the water and the other natural resources of Indonesia. In fact, the land redistribution
