Flux-Based Estimation of Field Capacity

Journal of Geotechnical and Geoenvironmental Engineering, 1999
Field capacity has been defined as the water content at which the drainage flux from a soil ceases, or becomes negligible. Field capacity is most commonly estimated as the water content at a pressure head of 1/3 bar, which ignores its flux-based nature.

Effects of a super-absorbent polymer derived from poly-γ-glutamic acid on water infiltration, field water capacity, soil evaporation, and soil water-stable aggregates

, 2020
The poly-γ-glutamic acid super-absorbent polymer (γ-PGA SAP) is an environmentally friendly material. Five different γ-PGA SAPs contents based on weight, including 0% (CK), 0.05% (T1), 0.10% (T2), 0.15% (T3), and 0.20% (T4), were added to the soil in ...

Adaptive capacity to climate change: A synthesis of concepts, methods, and findings in a fragmented field

WIREs Climate Change, 2019
Adaptive capacity is an important element of long‐term adaptation to climate change and is the focus of a rapidly growing body of research. Interdisciplinary growth has the potential to introduce new methods and insights, but it could also cause ...

A Field's Capacity to support a Butterfly Population

Nature, 1964
THE controversy among ecologists on ‘density dependence’ swelled out of all proportion due to differences among authors in the meaning and use of such words as ‘carrying capacity’, ‘competition’ and ‘density’. Beneath these unimportant disagreements, however, there lies at least one fundamental question which has seldom been investigated: Does an area ...

Heat capacity of Gd0.06Er0.94Al2 in magnetic fields

Journal of Applied Physics, 1988
We have measured the specific heat of an arc-melted specimen of Gd0.06Er0.94Al2 in applied magnetic fields of 1, 3, 5, and 8 T from 4.5 to 40 K, and in zero field from 1.4 to 98 K. Inspection of entropy versus temperature with the lattice included shows that the maximum adiabatic cooling is 13 K and occurs from 30 K at 8 T to 17 K at zero field.

Peak Capacity in Field-Flow Fractionation

Separation Science and Technology, 1981
Abstract Field-flow fractionation (FFF) peak capacity values have been computed with only two major assumptions: first, the plate height is supposed the sum of only two contributions, axial molecular diffusion and transversal nonequilibrium, and second, the steric effect has been neglected in the equations of retention and peak broadening.

Field Validation of Collaborative Capacity Audit

2008
Abstract : This phase of our study further develops and refines a collaboration capacity survey that was designed by the authors in 2003. Using verbal protocols with subject-matter experts in the DoD acquisition arena, field-testing, and a literature review, the researchers piloted alternative forms of the diagnostic survey.

Taking State-Capacity Research to the Field: Insights from Collaborations with Tax Authorities

Annual Review of Economics, 2019
No modern state can exist in the long term without effective taxation. Recent research emerging from close collaboration of academics with tax authorities has shed new light on how states can build such tax capacity.

Regenerative Capacity of Field Bindweed Roots

Weed Science, 1976
Lateral roots of a clone of field bindweed (Convolvulus arvensis L.) were dug each month for 12 months, cut into 6-cm long sections and grown in the dark on moist paper at 23 C to determine if regeneration varies seasonally. New shoots and roots were measured after 8, 11, and 14 days. After 14 days, 69% to 98% of the sections had produced shoots.
