OBJECTIVE To test the tensile properties of knotted suture made of 4 different suture materials and exposed to petroleum gauze. STUDY DESIGN We tested the tensile strength of United States Pharmacopeia size 0-0 gauge polydioxanone, polyglyconate, glycolide/lactide copolymer, and silk when exposed to petroleum packing or saline. Suture materials were randomized, and knots were tied and then ev...

Since the end of previous century, the role of petroleum as a raw material of synthetic surfactant gradually deflated due to the reasons such as decreasing of the relative abundance of petroleum, leading to soared prices of petroleum and increasing of carbon dioxide emission by heavy utilization of petroleum. Instead, the industries concerning in the surfactants and detergents are focusing on t...

A variety of factors, including concentration of oil, antibiotics, dyes, and inoculum washes, were examined to determine their effect on the total counts of microorganisms on oil-containing media. The media found to be best for enumerating petroleum-degrading microorganisms contained 0.5% (vol/vol) oil and 0.003% phenol red, with Fungizone added for isolating bacteria and streptomycin and tetra...

Software Interoperability for Petroleum Applications — In this introduction to the thematic dossier on software interoperability, we emphasise the key role of software for the petroleum industry, and we give market and technical motivations for interoperability. This is followed by a brief overview of the technologies used in the search for interoperability and by a summary of the five technica...

We present a coherent and unified group of general explanations for the various phase transitions, which may occur in the seven naturally occurring petroleum fluids with emphasis on their heavy organics. The seven petroleum fluids include, in the order of their fluidity, natural gas, near-critical gas-condensate, light crude, intermediate crude, heavy oil, tar sand and oil shale. At first the n...

Greenhouse gas emissions cause many global problems. Under the strong promotion of government’s two-carbon goals policy, China’s petroleum industry is actively carrying out application carbon capture, utilization, and storage (CCUS). The energy consumption in China are reviewed, importance process emission reduction clarified. applications, advantages, disadvantages sequestration technologies s...

In the presented research we have tested the application of photo ionization detector of ECOPROBE 5 analyzer to monitoring of low concentrations of petroleum products in water. Petroleum products are organic pollutants that are present in wastewater most frequently, which is caused by their broad applications and frequent incidents. Emergency leakage of petroleum and its products is predominant...

Many organizations interested in renewable, domestic energy have switched from petroleum diesel to biodiesel blends for use in transportation and heavy-duty equipment. Although considerable evidence exists on the negative health effects of petroleum diesel exhaust exposures in occupational settings, there has been little research examining biodiesel exposures. Working collaboratively with a loc...
