In vitro bioactivity of various pure flavonoids in ruminal fermentation, with special reference to methane formation
rumen ammonia Hohenheim Gas Test epicatechin isoquercetin luteolin-7-glucoside quercetin catechin tannic acid
2018/11/23
Polyphenols, like flavonoids, have been investigated when present in intact plants or in extracts as methane mitigating dietary supplements in ruminants. The aim of the present study was to examine pu...
BASELINE ERROR ANALYSIS AND EXPERIMENTAL VALIDATION FOR HEIGHT MEASUREMENT OF FORMATION INSAR SATELLITE
InSAR Height Measurement Baseline Error DEM Simulation Validation SRTM TerraSAR-X/TanDEM-X
2018/5/14
In this paper, we proposed the stochastic model of InSAR height measurement by considering the interferometric geometry of InSAR height measurement. The model directly described the relationship betwe...

2018/3/23
The paper focuses on the formation of Nanzhangzhuang ground fissure through emphatically analysing factors including the intersection fault dislocation, the deep ground-water over-exploitation togethe...
Multiple Dolomitization and Fluid Flow Events in the Precambrian Dengying Formation of Sichuan Basin, Southwestern China
Precambrian dolomite geological fluid flow meteoric water hydrothermal activity Sichuan Basin
2018/4/10
The Precambrian Dengying Formation is a set of large-scale, extensively dolomitized, carbonate reservoirs occurring within the Sichuan Basin. Petrographic and geochemical studies reveal dolomitization...
Mathematical modeling of heat transfer in counter-current multiphase flow found in gas-drilling systems with formation fluid influx
Gas-drilling Temperature Prediction Influx Joule–Thomson Cuttings
2018/4/2
The performance of gas-drilling (drilling oil and gas wells with air, nitrogen, or natural gas) is very unpredictable in many areas due to lack of proper design of drilling parameters because of limit...
Mineral composition and organic geochemistry of the Lower Cretaceous Xiagou Formation source rock from the Qingxi Sag, Jiuquan Basin, Northwest China
Mineral composition Geochemistry Source rock Xiagou Formation Qingxi Sag Jiuquan Basin
2018/4/2
The Lower Cretaceous Xiagou Formation contains the major source rocks for the crude oils discovered in the Qingxi Sag and the South Uplift in the Jiuquan Basin, northwestern China. The Xiagou Formatio...
Constraints on mechanisms of chondrule formation from chondrule precursors and chronology of transient heating events in the protoplanetary disk
chondrules refractory inclusions chondrule precursors transient heating
2017/4/10
The mineralogy, petrography, and oxygen-isotope compositions of porphyritic chondrules—dominant chondrule type
in most chondrite groups—suggest formation by incomplete melting of isotopically diverse...
Meteor induced ridge and trough formation and the structuring of the nighttime E-region ionosphere
Meteor induced ridge trough formation
2017/3/22
When meteor-generated plasma trails diffuse into the
ionosphere they create large ambipolar electric fields
mainly perpendicular to the Earth’s geomagnetic field
(B) and extending many kilometers f...
Microscopic characterization and formation mechanisms of deepwater sandy-debris-flow and turbidity-current sandstones in a lacustrine basin: a case study in the Yanchang Formation of the Ordos Basin, China
Sandy debris flow Turbidite Ordos Basin Petrology Reservoir properties
2018/4/2
Deep-water deposition is a current issue in sedimentological research. Sandy-debris-flow sandstones and turbidity-current sandstones are the main types of sandstone that are the focus of considerable ...
