in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
The aim, in almost all industries, is to have a high level of automation to increase productivity and efficiency. Industrial robots, which have been one important technology enabler in achieving this aim, are designed to perform repetitive, heavy, dirty and dangerous tasks. Within the oil and gas industry, robots have been used in very specific niche applications where the main driver has been ...
gas chromatography (gc) and gas chromatography mass spectrometry (gc-ms) were employed to determine the chemical composition of essential oil obtained from dry fruits of carum copticum. thymol (36.7%), -terpinene (36.5%) and -cymene (21.1%) were found to be the major constituents of the oil. the anti-bacterial activities of the oil were mainly investigated against food poisoning bacteria (sal...
Colorado and Pennsylvania, like parallel universes, provide strikingly different examples of how external forces affect the evolution of oil and gas conservation jurisprudence originating from a common starting point. This jurisprudence includes both “Classical” oil and gas conservation—measures to prevent waste of the oil and gas resource, and “Values” oil and gas conservation—measures that ad...
Oil-reservoir management using measurements and control techniques have been in use by oil and gas industries to improve the production and maintenance of the existing oil reservoirs. In the course of this project the applications of UWB radar systems and techniques to acquire near real-time information about the oil reservoir conditions are studied. Various oil reservoir structures such as oil...
Caspian Sea is the largest enclosed body of water on the earth. Since the collapse of Soviet Union in 1991 and discovering large oil and gas fields, some issues such as political, economic and environmental events, made the Caspian Sea important. The ecology of the Sea are being endangered due to several issues such as petroleum extraction, river and sea pollutions, water level rise, biological...
در حالت کلی معادلات حاکم بر یک مدل ریاضی از مخزن را نمی توان بوسیله روشهای تحلیلی حل کرد، در حالیکه یک مدل عددی می تواند بوسیله کامپیوتر جوابی تقریبی ارائه دهد. در این پایان نامه، یک دستگاه معادلات دیفرانسیل معمولی توسط گسسته-سازی معادله حاکم بر جریان شعاعی تک فازی نفت بسمت یک چاه (معادله چاه آزمایی) به دست آمده است. این سیستم شامل محاسبه تابع ماتریسی (exp(ka است که در آن k گام زمانی و a ماتریس...
One way to achieve economic growth is to invest in leading sectors. In addition, economic sectors can stimulate economic growth in other regions through the effects of spillover and feedback on their output. The purpose of this study is to identify the leading sectors, the effects of spillover and feedback on Oil-rich region. For this purpose, the two-region input-output table of Iranchr('39')s...
Nuclear Geophysics is essential to the oil, gas and uranium industries. The initial development of nuclear geophysics was focused on developing techniques needed by the oil industry. Developments in nuclear physics and computational analysis were immediately used this field. Today, techniques developed in nuclear geophysics are also used by the coal and metalliferous mining industries and contr...
