In this paper, a new approach is presented for improving image quality. It provides a new outlook on how to apply the enhancment methods on images. Image enhancement techniques may deal with the  illumination, resolution, or distribution of pixels values. Issues such as the illumination of the scene and reflectance of objects affect on image captures. Generally, the pixels value of an image is ...

To evaluate the reservoir characteristics of siliceous shale in Dalong Formation within late Permian intra-platform rift trough Western Hubei (China), we studied a drill core from well ED-2 Hubei. analyze physical characteristics, pore structure, methane adsorption performance, and their influences on reservoir, performed X-ray diffraction, total organic carbon (TOC) content, vitrinite reflecta...

Shale oil has become a global hotspot of unconventional exploration and development. In this study, the latest drill core experiment analyses Qingshankou Formation in northern Songliao Basin were used to evaluate its lithofacies classification, sedimentary environment, pore types, pore-throat structure characterization, shale potential. Lithofacies classification was determined according total ...

An assessment performed using raman spectroscopy has found space in the black shales of Cisuralian-age rocks Karoo Basin South Africa, particularly those from Guadalupian Ripon, Cisuralian Whitehill and Prince Albert Formations. It is used conjunction with geochemical screening techniques such as organic petrology programmed pyrolysis. In turn, combination these for thermal maturity sedimentary...

The Carboniferous–Palaeogene Wandel Sea Basin of eastern North Greenland (north 80°N, east 40°W) is an important piece in the puzzle Arctic geology. It particularly for understanding how Paleocene–Eocene convergence between Greenland, Canadian and Svalbard relates to compressional tectonics High Arctic, collectively known as Eurekan Orogeny. In this study, we present apatite fission-track analy...

The Cenomanian-Turonian Eagle Ford Formation is a widespread organic-rich mudrock in Texas and northern Mexico. economic significance of this unit for oil gas production USA has led to numerous investigations documenting its lithological geochemical variability. Comparatively little known about facies distribution source rock potential Here, we studied section the central part Sabinas basin. In...

Rock pyrolysis, organic petrology, vitrinite reflectance, gas chromatography-mass spectrometry (GC-MS) analysis, and biomarker compound analysis were performed to comprehensively analyze the geochemical characteristics of Jurassic Da’anzhai Member (J 1 da) shale strata in Yuanba Puguang areas northeastern Sichuan Basin. Then matter provenance sedimentary environment further analyzed. Finally, s...

epilepsy is among the most common disorders of the central nervous system and there is not an absolute method for its treatment. it has been shown that each seizure has a depressing effect on the following seizure. thus, finding the mechanisms responsible in this phenomenon can improve our knowledge toward new ways for epilepsy treatment. in this study, the role of adenosine a1 receptors in pos...

background: many of health system services are done in clinical counseling. a patient’s expectation of clinical consultation and physician office visits is to obtain diagnostic-remedial results, while such an expectation can be fulfilled only through an active relationship between the doctor and the patient. the aim of this study is to evaluate the quality of doctor- patient interaction in an e...

Lithium isotopes (δ7Li) in coals have been shown to increase with thermal maturity, suggesting preferential release of 6Li from kerogen porefluids. This has important implications for paleoclimate studies based on δ7Li buried marine carbonates, which may incorporate Li porefluids during recrystallization. Here, the content and isotopic composition macerals two coal seams intruded by dikes, were...
