 The agreement is concluded writing. If bank's certificates other documents that meet requirements legislation, regulations provisions which corresponds to written form (bank rules) c...
abstract petroleum pollution is one of the most common and dangerous pollutions that is due to petroleum industries such as refineries, and consequently of oil pipes and tanks leak causing environmental pollutions. one of the newest born technologies in this area is phytoremediation, in which plants are used for decreasing of petroleum pollution. this technology is used for remediation of soil,...
Two of the largest crude oil-polluted areas in the world are the semi-enclosed Mediterranean and Red Seas, but the effect of chronic pollution remains incompletely understood on a large scale. We compared the influence of environmental and geographical constraints and anthropogenic forces (hydrocarbon input) on bacterial communities in eight geographically separated oil-polluted sites along the...
Following a 120-h exposure period to 3 concentrations of oil dispersions (0.022 mg L(-1) , 1.8 mg L(-1) , and 16.5 mg L(-1) , plus controls) generated from a North Sea crude oil and a subsequent 21-d recovery, mortality, and several reproduction endpoints (egg production rates, egg hatching success, and fraction of females participating in reproduction) in Calanus finmarchicus were studied. Con...
Extracts from Curcuma zedoaria Inhibit Proliferation of Human Breast Cancer Cell MDA-MB-231 In Vitro
Objective. To evaluate the effect of petroleum ether extracts of Curcuma zedoaria on the proliferation of human triple negative breast cancer cell line MDA-MB-231. Methods. The reagents were isolated from Curcuma zedoaria by petroleum ether fraction. It was assayed by CCK8 for MDA-MB-231 cellular viability with various concentrations and days, cell cycle analyses, Western Blot analysis, and Rea...
Liquid transportation fuels derived from coal and natural gas could helpthe United States reduce its dependence on petroleum. The fuels could be produced domestically or imported from fossil fuel-rich countries. The goal of this paper is to determine the life-cycle GHG emissions of coal- and natural gas-based Fischer-Tropsch (FT) liquids, as well as to compare production costs. The results show...
Various concepts for oil evaporation prediction are summarized. Models can be divided into those models that use the basis of air-boundary-regulation or those that do not. Experiments were conducted to determine if oil and petroleum evaporation is regulated by the saturation of the air boundary layer. Experiments included the examination of the evaporation rate with and without wind, in which c...
The Pernambuco Basin represents one of the most prominent regions for deep water oil and gas exploration off the Brazilian coast. This study aims to identify and describe the occurrence of carbonate buildups in the offshore regions of the basin. The study was based on an analysis of a set of 143 2D time-migrated seismic sections that cover the offshore region of the Pernambuco Basin. An interpr...
Topological relationships between geological objects are of great interest in the process of mining and petroleum exploration. Indeed, adjacency, inclusion and intersection are common relationships between geological objects such as faults, geological units, fractures, reservoirs... However, in the context of 3D modeling, actual geometric data structures used to store objects of interest are no...
