Biodegradation characteristics of bitumen from the Upper Devonian carbonates (Grosmont and Nisku formations) in Alberta, Canada
In this study, we investigated the biodegradation processes of bitumen from the Upper Devonian carbonates (Grosmont and Nisku formations) in Alberta using GC and GC-MS analyses of four drilling cores. The anal...

Identification of Pseudoperonospora cubensis using real-time PCR and high resolution melting (HRM) analysis
To develop a molecular method to identify Pseudoperonospora cubensis in cucumber leaves with signs of downy mildew, we compared the nucleotide sequences of ribosomal DNA-internal transcribed spacer, cytochrome ox...

Estimation of the CO2 storage capacity of the structural traps in the southern Jeju Basin, offshore southern Korea, northern East China Sea
We analyzed 2-D seismic and well-log data from the southern Jeju Basin, offshore southern Korea, northern East China Sea to estimate the CO2 storage capacity of the structural traps in the area. Sand intervals wi...

Modeling of Spatiotemporal Thermal Response to CO2 Injection in Saline Formations: Interpretation for Monitoring
We evaluated the thermal processes with numerical simulation models that include processes of solid NaCl precipitation, buoyancy-driven multiphase SCCO2 migration, and potential non-isothermal effects. Simulation...

Molecular and isotopic signatures in sediments and gas hydrate of the central/southwestern Ulleung Basin: high alkalinity escape fuelled by biogenically sourced methane
Natural marine gas hydrate was discovered in Korean territorial waters during a 2007 KIGAM cruise to the central/southwestern Ulleung Basin, East Sea. The first data on the geochemical characterization of hydr...

Framboidal pyrites in late Quaternary core sediments of the East Sea and their paleoenvironmental implications
The three piston cores, collected from the East Sea, were analyzed to detect changes of sedimentary environment during the late Quaternary. The cores consist mainly of muddy sediments that are interbedded with...

Distribution of late Quaternary tephra layers in the western part of the Ulleung Basin, East Sea
Lithologies and stratigraphic relationships of late Quaternary core sediments were examined in three piston cores, recovered from the western Ulleung Basin. The approximately 8-m long cores consist of muddy se...

Abrupt climatic changes induced by ice-rafting events in the eastern North Atlantic during the late Quaternary: stable isotope and X-ray mineralogical analyses
Stable oxygen- and carbon-isotope and X-ray mineralogical analyses are used to obtain information on ice-rafting (Heinrich) events in the eastern North Atlantic during the last glacial period. A sediment core ...

The effect of swirling flow in the mixing chamber of atomizer and the length/diameter ratio of atomizer exit on the distribution of coal particles in CWM spray
This research is aimed to investigate how the swirling phenomena in an atomizer and the ratio of length/diameter of the atomizer exit affect the size distribution of coal particle in spray. CWM slurries are in...
