Using a New Glacial History Paradigm and Bald Eagle Through Valley Topographic Map Evidence to Determine Central Pennsylvania’s Geomorphic History, USA
《Open Journal of Geology》2024年第9期880-899,共20页Eric Clausen 
A new glacial history paradigm that describes huge and prolonged southwest-oriented meltwater floods flowing along the rising rim of a deep “hole” (which a large continental icesheet created and occupied) is used to...

The formation of orthogonal joint systems and cuboidal blocks:New insights gained from flat-lying limestone beds in the region of Havre-Saint-Pierre(Quebec,Canada)
《Journal of Rock Mechanics and Geotechnical Engineering》2023年第12期3079-3093,共15页Shaocheng Ji Yvéric Rousseau Denis Marcotte Noah John Phillips 
The authors express their gratitude to the Natural Sciences and Engineering Research Council of Canada for financial support through a Discovery Grant(Grant No.06408).
Vertical orthogonal joints are a common feature in shallow crustal rocks.There are several competing theories for their formation despite the ubiquity.We examined the exceptional exposures of orthogonal joints in flat...

Use of tree species by three species of Magicicada(Hemiptera:Cicadidae)in an Appalachian forest被引量：1
《Journal of Forestry Research》2023年第6期2051-2063,共13页Cindy Perkovich David Ward 
supported by the Herrick Foundation,Kent University。
Periodical cicadas(Magicicada spp.)are endemic to deciduous forests in the eastern United States.In successional forests,they must partition resources such as host trees to coexist.We measured tree size,emergence hole...

川东南下志留统与Appalachian泥盆系典型常压页岩气藏富集特征对比被引量：6
《地球科学》2023年第1期77-91,共15页蒋恕 张天宇 郭彤楼 何希鹏 高玉巧 薛冈 张培先 陈国辉 
国家自然科学基金重点项目(No.42130803);中石化华东分公司项目(No.34600000-19-ZC0607-0004)。
经各国持续攻关,超压页岩气在大多国家实现了商业化开发,但常压页岩气仅美国实现了商业化开发.为了摆脱我国高天然气对外依存度的现状,应尽快实现常压页岩气的商业化开发,亟需对其富集特征展开研究,期望对勘探开发方案的制定提供指导....

Leaching of lanthanide and yttrium from a Central Appalachian coal and the ashes obtained at 550-950℃被引量：2
《Journal of Rare Earths》2022年第5期807-814,I0005,共9页Ronghong Lin Yee Soong Bret H.Howard Murphy J.Keller Elliot A.Roth Ping Wang Evan J.Granite 
Project supported by the U.S.Department of Energy(DOE)National Energy Technology Laboratory(NETL)Research and Innovation Center(R&IC)Rare Earth FWP;supported in part by appointment(R.H.Lin)to the NETL Research Participation Program;sponsored by the U.S.DOE;administered by the Oak Ridge Institute for Science and Education(ORISE)。
In this work,we investigated leaching of lanthanide and yttrium(REY) from a Central Appalachian coal and its ashes obtained at 550-950℃ with the main purpose of understanding the impact of ashing temperature on REY l...

Predisposing factors’effects on mortality of oak (Quercus) and hickory (Carya) species in mature forests undergoing mesophication in Appalachian Ohio被引量：3
《Forest Ecosystems》2021年第1期81-94,共14页Don C.Radcliffe David M.Hix Stephen N.Matthews 
funded by United States Department of Agriculture Forest Service Northern Research Station agreement 15-CS-11242302-122(to S.N.M.);the Ohio Agricultural Research and Development Center SEEDS Project OHOA1572(to D.M.H.);The Ohio Agricultural Research and Development Center and The Ohio State University provided fellowship funding to D.C.R。
Background:Mature oak(Quercus spp.)and hickory(Carya spp.)trees are gradually being replaced by more shadetolerant tree species across the eastern U.S.,likely due to fire suppression and increased precipitation.Oaks a...

Numerical analysis for the prediction of bump prone conditions:A southern Appalachian pillar coal bump case study被引量：2
《International Journal of Mining Science and Technology》2021年第1期75-81,共7页Christopher Newman David Newman 
The authors would like to acknowledge Mr. Eric Legg and Mr.Gary Hensley who were fatally injured during the coal pillar bumpthat occurred on May 12, 2014 on the No. 1 Section in the 4 EastMain of Brody No. 1 Mine. May the continued analysis of the BrodyNo. 1 Mine bring the industry closer to understanding the coal pillarbump failure mechanism such that further loss of life can beprevented.
Two miners were fatally injured when a pillar bump occurred during retreat mining in a southern West Virginia coal mine.The mine was operating in the Eagle seam with overmining in the No.2 Gas and Powellton seams.A co...

Application of the coal mine floor rating(CMFR)to assess the floor stability in a Central Appalachian Coal Mine被引量：1
《International Journal of Mining Science and Technology》2021年第1期83-89,共7页Sena Cicek Ihsan Berk Tulu Mark Van Dyke Ted Klemetti Joe Wickline 
The authors would like to thank Dr.Serkan Saydam and Dr.Sungsoon Mo from the University of New South Wales for their kind support and guidance during the preparation of this manuscript.
Estimating the overall floor stability in a coal mine using deterministic methods which require complex engineering properties of floor strata is desirable,but generally it is impractical due to the difficulty of gath...
