Investigation and Stability Assessment of Three Sill Pillar Recovery Schemes in a Hard Rock Mine

open access: yesEnergies, 2022
In Canada, many mines have adopted the sublevel stoping method, such a blasthole stoping (BHS), to extract steeply deposited minerals. Sill pillars are usually kept in place in this mining method to support the weight of the overburden in underground ...

Experimental and numerical study of sluice gate flow pattern with non- suppressed sill and its effect on discharge coefficient in free-flow conditions [PDF]

open access: yesJournal of Hydraulic Structures, 2022
The purpose of this study is to investigate the flow pattern and discharge coefficient of sluice gate with the non-suppressed sill in experimental and numerical conditions. For this purpose, the sill of a rectangular cube in widths of 7.5, 10, 15, and 20

Does Neuroticism Disrupt the Psychological Benefits of Nostalgia? A Meta‐analytic Test

open access: yesEuropean Journal of Personality, EarlyView., 2020
Abstract Nostalgia, a sentimental longing or wistful affection for the past, confers self‐oriented, existential, and social benefits. We examined whether nostalgic engagement is less beneficial for individuals who are high in neuroticism (i.e. emotionally unstable and prone to negative affect).

Burial-Related Compaction Modifies Intrusion-Induced Forced Folds: Implications for Reconciling Roof Uplift Mechanisms Using Seismic Reflection Data

open access: yesFrontiers in Earth Science, 2019
Space for shallow-level sills and laccoliths is commonly generated by bending and uplift of overlying rock and sediment. This so-called “roof uplift” produces forced folds, the shape and amplitude of which reflect the geometry of underlying intrusions ...

Mineralogy and Petrology of an Olivine Diabase Sill Complex and Associated Unusually Potassic Granophyres, Sierra Ancha, Central Arizona [PDF]

open access: yes, 1969
The Precambrian Sierra Ancha sill complex, 700 to 800 feet thick, was intruded into flat-lying sedimentary rocks of the Apache Group in central Arizona. The bulk of the complex consists of a central layer of feldspathic olivine-rich diabase and upper and

Coefficient of Discharge for Free Flow Sluice Gates

open access: yesJournal of King Saud University: Engineering Sciences, 1999
This paper aims to investigate the effect of sill shape located under the sluice gate on the coefficient of discharge for free gate flow conditions. Both sill shape and sill height are studied. Shapes tested include both polygonal and non polygonal sills.

Fault inversion contributes to ground deformation above inflating igneous sills

open access: yesVolcanica, 2021
Magma emplacement is commonly accommodated by uplift of the overburden and free surface. By assuming this deformation is purely elastic, we can invert the shape and kinematics of ground deformation to model the geometry and dynamics of underlying ...

A Pivotal Stride towards Learner Autonomy: Utilising Language Learning Strategies in an ESL University

open access: yesREiLA, 2023
Research has revealed that utilisation of the English language learning strategies (ELLSs) is essential for supporting learner autonomy (LA). Yet, most of these studies focus on English as a foreign language, leaving studies on English as a second ...
