The coexistence of numerous Mississippi Valley-type (MVT) Pb-Zn deposits and oil/gas reservoirs in the world demonstrates that a close genetic link between them. northern Yunnan–Guizhou depression (NYGD) is tectonic unit containing Pb–Zn deposits, paleo-oil shale gas. However, previous studies on relationship hydrocarbon accumulation mineralization have been ignored. Maoping deposit large-sized...

Petroleum-based products are the major source of energy for industry and daily life. Petroleum is also the raw material for many chemical products such as plastics, paints, and cosmetics. The transport of petroleum across the world is frequent, and the amounts of petroleum stocks in developed countries are enormous. Consequently, the potential for oil spills is significant, and research on the ...

Purpose: To determine the effectiveness of lid scrub with petroleum jelly versus lid scrub with tea tree oil and tea tree facial wash in patients with symptomatic blepharitis associated with above-normal Demodex counts Methods: Patients with symptomatic anterior blepharitis (AB), meibomian gland dysfunction (MGD), or mixed blepharitis (MB) were recruited into the study. Pertinent data, includin...

The microbial community response to petroleum seepage was investigated in a whole round sediment core (16 cm length) collected nearby natural hydrocarbon seepage structures in the Caspian Sea, using a newly developed Sediment-Oil-Flow-Through (SOFT) system. Distinct redox zones established and migrated vertically in the core during the 190 days-long simulated petroleum seepage. Methanogenic pet...

Taknar Polymetal (Cu-Zn-Au-Ag-Pb) Deposit: A New Type Magnetite-Rich VMS Deposit, Northeast of Iran

PURPOSE A cardinal pathological feature of age-related macular degeneration (AMD) is the deposition of extracellular material between the retinal pigment epithelium (RPE) and Bruch's membrane, pathologically described as sub-RPE deposits. Both the presence and local organization of these deposits contribute to the clinical manifestations of AMD, including localized deposits clinically recognize...

the analyze of petroleum contracts demonstrate that in respect to the intensity of the cooperation between the state company and oil companies, we could find the different evaluative categories of the contracts on upstream oil industry.historically, the first generation of the petroleum contracts was the concession agreement in which the transferring of ownership was the base. the license agree...
