Great Decline

Abstract. Traces of Persian Culture at Barrus. From the middle of the first millenium C.E., or even before, Barus has been known as a trading mart for camphor and gold.Archaeological researches conducted in Barus from 1995 until 2005, as part of the cooperation program between The National Research and Development Centre of Archaeology, Indonesia and École française d'Extrême-Orient (EFEO), highlight the ancient relation between Persia and the Indonesia archipelago.A number of artefacts coming for Persia, made of stone and glass, as well as pottery, were collected during the excavations of the Lobu Tua site (mid-9th c.-end of the 11th c). Although analyses of the finds collected during the excavations at the Bukit Hasang site ( 12th c- beg. of the 16th c.) arenot completed yet, it is clear that at that time Barus experienced a great decline in the use of objects made of permanent material coming from the Middle East. But two inscribed tombstones, dating to the end of the 14th c. and to beginning of the 15th c, using Persian language or grammar prove that relation with Persia were not completely severed.Abstrak. Barus terkenal dari Asia Barat sampai Cina sebagai tempat perdagangan kuno untuk kamper dan emas sejak paling tidak pertengahan milenium pertama Masehi. Penelitian arkeologi yang telah dijalankan dari tahun 1995 hingga tahun 2005 di Barus, dalam rangka kerjasama Pusat Penelitian dan Pengembangan Arkeologi Nasional dengan École française d'Extrême-Orient (EFEO), menunjukkan hubungan yang berlangsung lama antara Persia dan Nusantara.Ekskavasi di situs Lobu Tua khususnya menghasilkan sejumlah artefak asal Persia dari batu dan kaca, serta sejumlah pecahan tembikar yang dipakai di Barus antara pertengahan abad ke-9 M dan akhir abad ke-I 1. Walaupun analisis mengenai hasil penggalian di situs Bukit Hasang (abad ke-12 hingga awal abad ke-16) belum selesai, sudah jelas bahwa pemakaian benda-benda permanen asal wilayah Timur Tengah pada umumnya menurun drastis di situs tersebut dibandingkan dengan Lobu Tua. Tetapi dua batu nisan dari akhir abad ke-14 dan awal abad ke-15, yang bertuliskan bahasa Persia atau menggunakan tata bahasa Persia, merupakan bukti bahwa hubungan dengan Persia tidak putus sama sekali.

Abstract To access a larger amount of pay zone, well trajectories are becoming longer and more complex, creating greater challenges for running completion liners. A liner shoe is a casing accessory tool that aids in the running of completion liners in long wells by allowing auto-filling of the liner and enabling pumping through the bottom of the liner. Upon reaching planned liner depth, the liner shoe is closed to allow for pressure testing and subsequent completion operations. Conventional methods used to close a liner shoe involve well intervention to set plugs or by dropping a ball, and there are inherent costs and risks associated with these operations. This paper presents the development and deployment of a remotely activated electronic liner shoe (ELS) for offshore applications that enables interventionless closing of the liner shoe, thereby improving operational efficiency, and reducing potential operational issues that could occur while closing the liner shoe conventionally. The ELS allows the operator to precisely control when the liner shoe closes – either based on pre-programmed pressure signals, a timer, or a combination of the two. A major operator in the Middle East required an ELS to be developed and qualified specifically for their offshore well conditions. A new technology qualification program was devised in collaboration with the operator to qualify both the electronic and mechanical functionalities of the tool. This paper documents the methods and results of the extensive qualification test program. The development and qualification process were successfully completed within 10 months at research and development facilities in Norway. Following qualification testing, the ELS was first deployed for the operator in an offshore well in Q4 of 2019. Operational considerations in programming the remote functionality of the tool is presented in this paper. After a successful field trial, the ELS has been run in more than 15 offshore wells and has become the standard option in the operator's completion program.

AAC Big Ben is a high yielding, soybean cyst nematode resistant food-grade soybean [Glycine max (L.) Merr.] cultivar with yellow hilum and acceptable processing quality for foreign and domestic tofu, soymilk, and miso markets. AAC Big Ben was developed at the Agriculture and Agri-Food Canada (AAFC) Harrow Research and Development Centre (Harrow-RDC), Harrow, ON. AAC Big Ben is adapted to areas of southwestern Ontario with 3300 or more crop heat units and has a relative maturity group of 2.3 (MG 2.3).
