The German Soil Systematics and the Rationale Behind Its Revision

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.

A novel, free regional conference model to increase interest and engagement of medical trainees in pediatrics and pediatric gastroenterology research

JPGN Reports, EarlyView.
Abstract Declining interest in pediatrics, contraction of the pediatric gastroenterology fellowship applicant pool, and the long‐standing erosion of the physician–scientist workforce threaten the future of pediatric academic medicine. Cost and logistical barriers to traditional academic conferences disproportionately affect trainees from ...

Planting Density Effect on Soil Functions With Specific Response to Rhizobacteria in Drought‐Prone Maize Field in the Yunnan Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Soil multifunctionality (SMF) governs terrestrial biogeochemical cycles and ecosystem services, yet whether belowground SMF exhibits saturating density‐dependent responses analogous to the aboveground constant final yield law remains unclear. In a two‐year field experiment across five planting densities (D1–D5) in drought‐prone maize farmland ...

CFD–DEM Modelling of Ground Collapse Induced by Underground Pipeline Leakage in Water-Rich Sand Layers

Modelling
Urban underground pipeline aging and leakage can result in soil erosion and ground collapse, constituting a major threat to urban public safety. To investigate this disaster mechanism, this present study established a two-dimensional numerical model ...

Corrosion of Potential Canister Materials During Oxic to Anoxic Transient in Compacted Bentonite

Materials and Corrosion, EarlyView.
A comprehensive analytical approach was applied to investigate material degradation phenomena of cast iron and copper as potential canister materials for the safe disposal of high‐level radioactive waste, as well as compacted bentonite exposed to artificial water relevant for disposal. ABSTRACT The long‐term performance of the engineered barrier system

Developing the Dopamine D3 Receptor (D3R) Antagonist, (R)‐VK4‐116, as a Non‐Opioid Medication for the Treatment of Opioid Use Disorder

Medicinal Research Reviews, EarlyView.
ABSTRACT Opioid use disorder (OUD) remains a major global health challenge, and currently approved treatments (methadone, buprenorphine, and naltrexone) are all opioid receptor‐targeting drugs with limitations in access, adherence, stigma, and use in polysubstance use disorders. Because the dopamine D3 receptor (D3R) is enriched in limbic brain regions
