Multilevel Collapsibility of Loess under Irrigation in Jinya Town, Gansu Province, China

open access: yesAdvances in Civil Engineering, 2019
The collapsibility of loess has constantly been a major problem in engineering geology. The determination of the collapsibility process and characteristics of loess are crucial to foundation construction and residents’ life in the Loess Plateau.

Collapse of rockfill

open access: yesInternational Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1991
Os materiais de enrocamento exibem deformações devidas à molhagem ou saturação. Nesta comunicação são apresentados resultados de enrocamentos de baixa e elevada resistência ensaiados em cmaras de compressão unidimensional e compressão triaxial com vista à quantificação do fenómeno.

The Relative Contributions of Arousal Presence and Arousal Intensity to Post‐Respiratory‐Event Ventilation in Obstructive Sleep Apnea

open access: yesJournal of Sleep Research, EarlyView.
In obstructive sleep apnea, the breathing after each obstructive event is affected by cortical arousal. Across two cohorts (N = 1781 and N = 67), arousal presence raised post‐event ventilation by 17–30%Eupnea, with each intensity step adding 1–4%Eupnea, independent of chemoreflex drive.

The Effects of Nasal and Multi‐Level Upper Airway Surgery on Upper Airway Collapsibility and Non‐Anatomical Endotypes in People With Obstructive Sleep Apnoea—A Pilot Study

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Nasal breathing is the preferred route of breathing during sleep. Indeed, nasal blockage can cause obstructive sleep apnoea (OSA) in otherwise healthy people. Whilst multi‐level pharyngeal surgery reduces OSA severity, efficacy varies and changes in OSA pathophysiology post‐surgery have not been well characterised.

Collapses Ahead: Foundations for a Sociology of Collapse

open access: yesSocijalna ekologija
Collapse has long been studied in archaeology, history, and ecology, but sociology has yet to systematically address it as a distinct social process. This article lays the groundwork for a sociology of collapse by synthesising major explanatory traditions—from ecological determinism and civilisational cycles to systemic, risk, and acceleration theories—

Does Hypoxic Burden Better Explain Sex Differences in Functional Impairments Than Apnoea‐Hypopnoea Index in Obstructive Sleep Apnoea?

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Women with obstructive sleep apnoea (OSA) report more severe functional impairments than men, despite lower apnoea‐hypopnoea index (AHI) values. This raises questions about the adequacy of AHI for capturing OSA severity. We explored sex differences in functional outcomes in OSA patients and examined whether AHI or hypoxic burden (HB) better ...
