in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Strategic planning of technology in Iran's oil industry has a long history, however, the knowledge-based sectors of the oil industry, despite their different characteristics, have been less exposed to such experiences, and hence the study of the experience in one of the key sub-sectors of this industry, namely the exploration geochemical sector, can be innovative. This article seeks to answer t...
To meet future global oil and gas demands, unconventional gas resources will play an important role in the U.S and world energy supply. To develop unconventional gas resources, we must first identify their occurrences and quantify their potential. The analog methodology that provides supplementary analysis to characterize the less accessible reservoirs has been employed in the oil & gas industr...
biodegradation of petroleum hydrocarbons (20 g/kg dw soil) was investigated in 3 media, differing in the kind of petroleum fractions. in the laboratory experiments, during 5 months, the activities of petroleum hydrocarbon-degrading microorganisms and dehydrogenase activity of soil was determined. gas chromatographic analysis showed the biological decontaminations for gas oil, kerosene and synth...
abstract the aim of this study was threefold: (1) to investigate the relationship between knowledge of semantic prosody and efl learners general language proficiency; (2) to examine the relationship between qualitative as well as quantitative knowledge of words, and (3) to compare the performance of efl learner on receptive and productive measures of semantic prosody. the study is based on a...
Gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. Experimental studies showed that an application of a combined technology of Gas Assisted Gravity Drainage (GAGD) and Vapor Extraction (VAPEX) could increase final oil recovery of a candidate viscous oil reservoir. In this paper the results of laboratory investigation are presented, including Pressure-Volu...
The use of induced polarization (IP) methods in oil and gas exploration dates back to the 1930s, but the validity of anomalies has been difficult to establish. Although recent geochemical and downhole research has verified the source of IP anomalies in some geologic environments, the influence of cultural (anthropogenic) features on the electrical data remains a serious stumbling block to the a...
Background and objectives: The majority of the Achillea spp. are used as medicinal plants with therapeutic applications worldwide. Achillea aucheri was selected in our study to assess its essential oil chemical composition along with antimicrobial evaluation. Methods: The essential oil of A. aucheri achieved ...
