Stability Analysis of “Support-Surrounding Rock” System for Fully Mechanized Longwall Mining in Steeply Dipping Coal Seams

open access: yesShock and Vibration, 2022
The key to safe and efficient longwall mining of steeply dipping seams lies in the stability control of the “support-surrounding rock” system. This study analyzes the difficulties encountered when controlling the stability of the support during the ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Infrasound early warning model for debris flow in a typical drainage basin in Beijing mountainous area

open access: yes地质科技通报
Objective Infrasound is an effective approach for debris flow warning. Traditional threshold-based warning methods focus solely on individual infrasound characteristics, which can lead to false alarms or missed detections.

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

HAZARDS ANALYSIS. RADIOLOGICAL HAZARDS [PDF]

open access: yes, 1962
ABS>Doses were calculated for persons off site and in the EGCR cortrol room following the maximum credible accident (depressurization), and for the public due to normal operational stack release. The assumptions and calculations used in the study are given in detail. (D.L.C.)

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Hydrologic sensitivity of flood runoff and inundation: 2011 Thailand floods in the Chao Phraya River basin [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2015
The Thailand floods in 2011 caused unprecedented economic damage in the Chao Phraya River basin. To diagnose the flood hazard characteristics, this study analyses the hydrologic sensitivity of flood runoff and inundation to rainfall. The motivation is to

The First-Year Gateway Experience: A Groundbreaking Model [PDF]

open access: yes, 2014
Based on calls for a paradigm shift in higher education, which have appeared in the literature for years (Barr &Tagg, 1995; Tagg, 2003, Bryant University transformed its first-year experience into an innovative model, The First-Year Gateway). Informed by
