Partial regularity for flows of H-surfaces, II

open access: yesElectronic Journal of Differential Equations, 1999
We study the regularity of weak solutions to the heat equation for H-surfaces. Under the assumption that the function $H:{Bbb R}^3 o {Bbb R}$ is bounded and Lipschitz, we show that the solution is $C^{2,alpha}$ on its domain, except for a set of measure ...

Hardy and Hardy-Sobolev Spaces on Strongly Lipschitz Domains and Some Applications

open access: yesAnalysis and Geometry in Metric Spaces, 2016
Let Ω ⊂ Rn be a strongly Lipschitz domain. In this article, the authors study Hardy spaces, Hpr (Ω)and Hpz (Ω), and Hardy-Sobolev spaces, H1,pr (Ω) and H1,pz,0 (Ω) on , for p ∈ ( n/n+1, 1].

Bahaman patch reefs: Numerous and neglected

open access: yesThe Depositional Record, EarlyView.
Abstract Phanerozoic patch reefs are extensively studied because they are abundant and are potential reservoirs for valuable fluids. In contrast, geologic studies of modern reefs have largely focused on platform margins, leaving patch reefs comparatively neglected. What conditions favour patch‐reef development?

Sediment‐stressed reefs over the past 420 Myr

open access: yesThe Depositional Record, EarlyView.
In order to fully elucidate the relationship between siliciclastic sedimentation and reef development, there needs to be a significant step change in how we record ancient and recent reefs. Only through the collection of constrained quantitative data, we can progress beyond the largely conjectural associations postulated for many ancient reefal systems.

Orbital and eustatic control of basin hydrology during the first stage of the Messinian Salinity Crisis

open access: yesThe Depositional Record, EarlyView.
The paleo‐hydrology of the Sorbas Basin (SE Spain) and the wider Mediterranean region during the deposition of the Primary Lower Gypsum (PLG) stage of the Messinian Salinity Crisis, from ~5.97 to ~5.60 Ma, was affected by tectonics, precession‐forced climate oscillations, and eustatic sea‐level change.

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

open access: yesDeep Underground Science and Engineering, EarlyView.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

Evaluation of fall‐seeded cover crops for grassland nesting waterfowl in eastern South Dakota

open access: yesWildlife Society Bulletin, EarlyView., 2023
Cover crops are experiencing a revival among Midwestern farmers, and we assessed their attractiveness and safety for nesting ducks in South Dakota. Nest success was markedly lower in cover crops than in perennial cover during both years of our study, including 2019 which was a best‐case scenario for cover crops, with extremely wet conditions delaying ...
