Soil Solution Analysis With Untargeted GC–MS—A Case Study With Different Lysimeter Types

open access: yesFrontiers in Earth Science, 2021
Surface-sourced organic compounds in infiltrating waters and percolates are transformed during their belowground passage. Biotic and abiotic processes thereby lead to continuously changing chemical environments in subsurface compartments.

Storage seepage and evaporation: a summary of the results from the measurement of seepage and evaporation losses from 136 on-farm storages across the cotton industry [PDF]

open access: yes, 2011
On-farm storages can be a major source of water loss on cotton farms. Previous studies in the Macintyre valley (Dalton 2001)indicated seepage losses of between 2% and 10% and evaporation losses of between 14% and 40% of all farm water in a year. In order

Preparation and Performance Evaluation of a Self‐Generated Particle Plugging Agent Based on Thermosetting Resin

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A thermosetting in situ curing resin microsphere system has been developed. It has controllable phase transition time and particle size. This system addresses the current challenges of low strength, shear susceptibility, and short phase transition time in polymer microsphere blockers and thermoplastic particle blockers.

Factors affecting the estimation of seepage rates from channel automation data

open access: yes, 2014
Seepage is the dominant process by which water is lost from well-managed earthen distribution channels. Pondage tests are acknowledged as the best direct method for seepage measurement, and the recorded water level data from automated systems during ...

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

open access: yesThe Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

Detection of seepage zones in artificial levees: A case study at the Körös River, Hungary

open access: yesOpen Geosciences
This study evaluates the impact of seepage on the integrity of artificial levees in low-lying regions, with a particular focus on Hungary, where levees built over a century ago lack comprehensive construction documentation, complicating current ...

Modified Shields number for sediment incipient motion around a pile with impact of three-dimensional seepage in a porous seabed

open access: yes, 2021
Sediment incipient motion is one of main forms to undermine the stability of piled-type foundations in the coastal environment. Unlike previous studies ignoring the impact of seabed seepage, the three-dimensional seepage is included in the process of ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

open access: yesAnimal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.
