Gas chromatography (GC), gas chromatography-mass spectrometry (GC/MS), supercritical fluid chromatography (SFC), elemental analysis, infrared absorption spectroscopy (IR), thermal analysis (TG/DTA), Rock-Eval pyrolysis, as well as viscosity and density analysis revealed that oil sands from Qaidam basin, Qinghai Province of China, are highly concentrated in light components (£C23), with saturate...

This study relates to the input and fate of fossil organic matter (FOM) in the modern environment, and focuses on two experimental watersheds overlying Jurassic marls: Le Laval and Le Brusquet (1 km 2 in area), located near Digne, Alpes-de-Haute-Provence, France. Considering that FOM delivery is mainly a result of different processes affecting sedimentary rocks [(bio)chemical and mechanical wea...

A~tract--The Cretaceous/Tertiary (K/T) boundary is marked by extensive changes in the sedimentary fossil record of continental and marine life. Organic matter in sediments from above and below the K/T boundary has been studied to identify consequences of the biotic extinctions and of the changes in biological productivity which occurred at this time. Data from locations encompassing a variety o...

In this paper, we describe the system jointly developed by IBM Research and Columbia University for video copy detection and multimedia event detection applied to the TRECVID-2010 video retrieval benchmark. A. Content-Based Copy Detection: The focus of our copy detection system this year was fusing three types of complementary fingerprints: a keyframe-based color correlogram, SIFTogram (bag of ...

Understanding the performance and role of each formation in a petroleum play is crucial for the efficient and precise exploration and exploitation of trapped hydrocarbons in a sedimentary basin. The Lorestan basin is one of the most important hydrocarbon basins of Iran, and it includes various oil-prone potential source rocks and reservoir rocks. Previous geochemical studies of the basin were n...

The purpose of the study in Karangkobar area was to investigate source rock potential fine-grained surface samples clastic sediments. use for Indonesia is still limited. We conducted geochemical laboratory analyses this research, including Total Organic Carbon (TOC), Rock-Eval Pyrolysis (REP), and Gas chromatography–mass spectrometry (GCMS). Seventeen have been analyzed their TOC content. resul...

We determine the organic matter content, its thermal maturity, genetic type, and source rock potential of Miocene sedimentary rocks in Czech Carpathian Foredeep. In Republic Foredeep represents a peripheral foreland basin formed due to tectonic emplacement loading Alpine-Carpathian Thrust Wedge onto passive margin Bohemian Massif. Random vitrinite/huminite reflectance measurements maceral analy...

the purposes of this article are studying the effects of oxygen presence on waste wood pyrolysis process in order to produce bio-char. to reach the goal, cubic samples of size 2.5 cm pyrolized at 300 and 400 °c. the surface and center temperatures of samples were measured and their mass losses were calculated from the ratio of pyrolized mass to initial mass of the sample. increase in temperatur...

Brewery`s spent grain (BSG) and sewage sludge (SS) were used as raw material at the temperature from 400°C to 700 °C and limited oxygen (O2<5%) conditions to prepare biochar (BC). One aim is to examine the BC characterization prepared under different temperatures and various proportions of SS. Another aim is to find the optimum preparation conditions of BC for treating wastewater. Results showe...

Nanostructural evolution of II-VI semiconductors emerges as a hot research field because it offers a novel route for the synthesis of functional semiconductor nanomaterials. Here, we report a "top-down" process of structural evolution from two dimensional Cd(2)Se(2)(pa) hybrid structures to zero- or one- dimensional CdSe nanostructures. We firstly synthesized the Cd(2)Se(2)(pa) hybrid by a faci...
