Three-Dimensional Morphology and Connectivity of Organic Pores in Shale from the Wufeng and Longmaxi Formations at the Southeast Sichuan Basin in China

open access: yesGeofluids, 2021
Organic pores play an important role in shale reservoirs. Organic pores occur where shale gas was produced and accumulated. However, there is little scientific understanding of the distribution and connectivity of organic pores.

Enriched order polytopes and enriched Hibi rings [PDF]

open access: yesEuropean Journal of Mathematics, 2020
AbstractStanley introduced two classes of lattice polytopes associated to posets, which are called the order polytope $${{\mathscr {O}}}_P$$ O P and the chain polytope $${{\mathscr {C}}}_P$$ C P

Contract and Unjust Enrichment: Lessons from History?

open access: yes, 2023
This chapter suggests that supporters of unjust enrichment may have adopted an unduly narrow view of contract law which is at odds with the historical narrative. The term ‘quasi-contract’ is commonly equated with a fictious implied contract.

Effects of environmental enrichment on the behaviour of captive great green macaws (Ara ambiguus) [PDF]

open access: yes, 2022
openThe great green macaw is a species threatened by extinction and classified as critically endangered by the IUCN. Thus, ex-situ maintenance plays a significant role in the conservation of this species and can be considered an insurance against ...

Unjust enrichment and equity

open access: yes, 2020
This chapter addresses the complex relationship between unjust enrichment and equity. It examines their theoretical relationship to one another as categories, the role of ideas of conscience, unconscionability and ‘unconscientious retention’ as the ...

Evaluating Pore Structure of Shale Reservoirs through Pore Space Multifractal Characterization

open access: yesGeofluids, 2023
Characteristics of pore structure are crucial to oil exploration and development in shale reservoirs, but practical evaluation of shale pore structure remains a longstanding challenge.

A partition of unity FEM for time-dependent diffusion problems using multiple enrichment functions [PDF]

open access: yes, 2013
An enriched partition of unity FEM is developed to solve time-dependent diffusion problems. In the present formulation, multiple exponential functions describing the spatial and temporal diffusion decay are embedded in the finite element approximation ...

Keeping Environmental Enrichment Enriching

open access: yesInternational Journal of Comparative Psychology, 2002
The use of novel objects as environmental enrichment devices is a key aspect of many environmental enrichment programs, regardless of whether the animals being enriched are housed in aquaria, zoos, or laboratories. The effectiveness of novel objects as enrichment devices depends on a number of factors, many of which are based on findings from ...
