Research on Optimal Width of Coal Pillars in Both Sides of Abandoned Mining Areas and Tunnel Control Technology

open access: yesEnergy Science &Engineering, EarlyView.
This study primarily investigates the optimal width for coal pillar retention in both sides of the worked‐out face section. Taking the 42201 haulage roadway of the 42201 working face at Shengxin Coal Mine as the primary research target, it analyses the optimum width for coal pillar retention through theoretical calculations, numerical simulations, and ...

The Distribution Characteristics of Frost Heaving Forces on Tunnels in Cold Regions Based on Thermo-Mechanical Coupling

open access: yesApplied Sciences
To address the freezing damage to tunnel lining caused by frost heaving of the surrounding rock in water-rich tunnels in cold regions, a numerical thermo-mechanical coupling model for tunnel-surrounding rock that considers the anisotropy of frost heave ...

Oscillometric assessment of bronchodilator response in horses with severe asthma during remission

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background During clinical remission of severe equine asthma (SEA), affected animals can be challenging to distinguish from healthy horses. In humans, the degree of bronchodilation achieved with a β2‐adrenergic bronchodilator is helpful in differentiating asthmatics from healthy subjects.

Correlation Analysis on Frost Heaving Ratio of Subgrade Soil and Plasticity Index under Freeze-Thaw Cycles

open access: yes, 2011
Three kinds of subgrade soils with different plasticity index are selected from seasonally frozen soil region. Frost heaving ratio of volume and height was performed on the samples exposed to 0 to 8 times closed-system freeze-thaw cycles.

Keeping their powder dry: Purity, pollution, and handgun ownership among Jewish women in Israel

open access: yesFeminist Anthropology, EarlyView.
Abstract This article examines the gendered practices through which Jewish women in Israel experience and negotiate personal handgun ownership in everyday life. Drawing on interviews, participant observation in gun‐related spaces, and analysis of women‐only online forums, we explore the expanding participation of Jewish women in civilian gun ownership,

Aftasten/Tantear: A sensorial, coalitional wayfinding among Muslim runners

open access: yesFeminist Anthropology, EarlyView.
Abstract Muslim recreational runners in Muslim‐minority settings that take up running as their preferred form of leisure indicate that they feel they have to navigate a sense of exclusion when running outdoors. This article explores the process of exploration and sensing in public, represented by the Dutch verb aftasten, to investigate the way Muslim ...

Thermochronologic Constraints on the Extensional History of the Ibex Hills, Southeastern Black Mountains, Death Valley, California

open access: yesGeological Journal, EarlyView.
A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

Three-dimensional Unsteady Flow over a Heaving Rectangular Wing [PDF]

open access: yes, 2013
Three-dimensional unsteady RANS computations are performed for the flow past a pure heaving/plunging rectangular wing to study the effect of reduced frequency and heaving amplitude on the thrust generation and propulsive efficiency.
