Abstract Natural gas has become an important source of energy in the world. Throughout the 19th century, natural gas was used almost exclusively as a source of light and its use remained localized because of lack of transport structures, making it difficult to transport large quantities of natural gas long distances. There was an important change in 1890 with the invention of leak-proof pipeline couplings, but transportation of natural gas to long distance customers did not become practical until the 1920s as a result of technological advances in pipelines. Moreover, it was only after World War II that the use of natural gas grew rapidly because of the development of pipeline networks and storage systems. Gas pipe lines are operated under steady state conditions. However, when transporting high temperature wet gas the gas getting cooled and heavy components condensate, Hence, pigs is usually are wanted to clean the pipe line to reduce pressure drop along the pipe In this study an existing pipeline was studied under steady and unsteady state. HYSYS and ProFES programs were utilized. Result show that gas temperature changes with time and distance. Results show that temperature and gas approach the ambient temperature at about 20 Km of pipe line length consequently, liquid phase volume fraction increase in first 20 Km of the pipe.

A Pilot study on Open Educational Resources and experimental carried out by higher educational in Libya

Open Educational Resources (OER) is simple but powerful educational materials made freely and legally available on the Internet for anyone to reuse, revise, and redistribute. These materials have the potential to give people everywhere equal access to our collective knowledge and provide many more people around the world with access to quality education by making lectures, books and curricula widely available on the Internet. In this paper a brief history of OER is stated and then Creative Commons Licenses are explained and finally the steps to implement OER in Libya are outlined

influence of fine aggregate type and content on the properties of grout for two stageconcrete

Two-stage concrete (TSC) is characterized by its exceptional placement technique, whereby aggregates are first pre-placed in the formwork then injected with a flowable grout. The quality of TSC grout is a controlling factor of the mechanical strength and durability of TSC. Therefore, this study investigates the properties of grout mixtures incorporating two types of fine aggregate including natural sea sand and crushed fine aggregate. The grout mixtures proportions were prepared at a water-to-cement ratio (w/c) of 0.45. Three fine aggregate-to-cement ratios (fa/c) of 0.5, 1.0 and 1.5 were tested. Results indicate that grout mixtures made with natural sand exhibited higher flowability and lower bleeding resistance than those made with crushed fine aggregate. Moreover, increasing the fine aggregate content reduced the grout flowability, while it improved the bleeding resistance and compressive strength. It was concluded that grout mixture made with crushed fine aggregate, (fa/c) = 1.0, and 0.8% high-range water-reducing admixture (HRWRA) was the best for successful TSC grout since it exhibited acceptable flowability, excellent bleeding resistance and high compressive strength. arabic 14 English 79
