Neutron irradiation of alloy N and 316L stainless steel in contact with a molten chloride salt
Ezell, N. Dianne Bull,Raiman, Stephen S.,Kurley, J. Matt,McDuffee, Joel Korean Nuclear Society 2021 Nuclear Engineering and Technology Vol.53 No.3
Capsules containing NaCl-MgCl<sub>2</sub> salt with 316L stainless steel or alloy N samples were irradiated in the Ohio State University Research Reactor for 21 nonconsecutive hours. A custom irradiation vessel was designed for this purpose, and details on its design and construction are given. Stainless steel samples that were irradiated during exposure had less corrosive attack than samples exposed to the same conditions without irradiation. Alloy N samples showed no significant effect of irradiation. This work shows a method for conducting in-reactor irradiation-corrosion experiments in static molten salts and presents preliminary data showing that neutron irradiation may decelerate corrosion of alloys in molten chloride salts.
Korean Cool: The impact of geek, tradition, and pop culture glocalization from Korea to America
( Karol Chandler-ezell ) 현대영미어문학회 2015 현대영미어문학회 추계학술대회 발표논문집 Vol.2015 No.-
Beginning with culture history writings from Daniel Tudor and Euny Hong and moving into anthropological theory on culture change; this presentation examines the way Korea’s unique traditions, social structure, and pop culture movements have influenced American “glocalized” culture. Local movements in Korean music, entertainment, fashion, and pop culture have created a distinct cultural identity with great international success thanks to the Hallyu. The Hallyu doesn’t end with Kpop music, K-drama, or even tech, however. Korean food, especially Korean-fusion food that mixes the traditional Korean cuisine with local and global tastes, has permeated the American food scene. Korean tech has become a symbol of reliability and innovation that supplants former Japanese and American products, making Korean the hot global flavor for pop, tech, and geek culture in the U.S. and beyond. Underlying all of this is the economic and technological success of the Republic of Korea itself. This combination of technological and pop culture success has made Korean culture the new local, global cool; as well as a fascinating model for reimagining revitalization movement theory within the context of glocalization.
STEREOSELECTIVITY IN ^4π_s^+4π_s PHOTOCYCLOADDITION OF 1,3-CYCLOHEXADIENE TO ARENES
Yang, Nien-chu C.,Kim, Sung Sik,Gan, Hong,Masnovi, John M.Yang, Nien-chu C.,Rafalko, P. White,Ezell, Edward F.,Lenz, George R. 全北大學校 基礎科學硏究所 1991 基礎科學 Vol.14 No.2
The stereoselectivity in photocycloaddition of 1,3-cyclohexadiene to unsymmetrical arenes may be controlled by the secondary orbital interactions between LUMOs of the arene and the diene.
Guided wave formation in coal mines and associated effects to buildings
Guzin G. Uyar,Ezel Babayigit 국제구조공학회 2016 Structural Engineering and Mechanics, An Int'l Jou Vol.60 No.6
The common prospect in diminishing mine-blast vibration is decreasing vibration with increasing distance. This paper indicates that, contrary to the general expectancy, vibration waves change their forms when they are travelling through the low velocity layer like coal and so-called guided waves moving the vibration waves to longer distances without decreasing their amplitudes. The reason for this unexpected vibration increase is the formation of guided waves in the coal bed which has low density and low seismic velocity with respect to the neighboring layers. The amplitudes of these guided waves, that are capable of traveling long distances depending on the seam thickness, are several times higher than that of the usual vibration waves. This phenomenon can many complaints from the residential areas very far away from the blasting sites. Thus, this unexpected behavior of the coal beds in the surface coal mines should also be considered in vibration minimization studies. This study developed a model to predict the effects of guided waves on the propagation ways of blast-induced vibrations. Therefore, vibration mitigation studies considering the nearby buildings can be focused on these target places.
