Ughelli Power Plant. Transcorp Power Limited's Ughelli Power Plant is a gas-fired thermal plant located in Ughelli, Delta State in the Niger Delta region of Nigeria. It is the largest fossil-fuel based power-generating station in the country. The plant has an installed capacity of 972 MW and is capable of generating 2,500 GWh of electricity annually.

The plant meets current world specifications for plants of its type and includes an updated control room, a switchgear room, a staff training school, and recreational facilities.

Most of the electricity produced by Ughelli is transported through a network of conductors, to the national grid.

The plant is an asset of Transnational Corporation of Nigeria Plc (Transcorp)’s power subsidiary, Transcorp Ughelli Power Limited (Transcorp Power).

History 
The station was built in 1964 with an installed capacity of 2X36MW or 72MW from two Stal-Laval gas turbines and began operations in 1966. Then the station was called Delta I under the Electricity Corporation of Nigeria (ECN), a precursor to the Nigerian Electric Power Authority (NEPA) and its successor, the Power Holding Company of Nigeria (PHCN).

In 1975, six units of General Electric (GE) Frame 5 gas turbines (20MW each) were installed in the station known as Delta II, after the merger of Niger Dam Authority (NDA), Kainji, and the ECN to form the National Electric Power Authority (NEPA).

In 1978, an additional six units of GE Frame 5 gas turbines, like the ones installed in 1975, were added to Delta Power Station (Known as Delta III) to boost the installed capacity to a total of 312MW. In 1991, six 100MW (600MW) GE Frame 9 gas turbines were added. From 2000 to 2008 Delta II and Delta III GE units were upgraded to 150MW stations each: built by Hitachi. The control systems were upgraded to Mark V, a fully computerized control system for Delta II and III. While Delta I was scrapped. Delta IV control system was also upgraded to Mark V by GE of USA which built the station.

On September 25, 2012, Transcorp Ughelli Power Limited (TUPL) (which comprises Wood Rock Energy Resources Limited, Symbion Power LLC, Thomassen Holding Limited, Medea Development S.A., Tenoil Petroleum and Energy Services Limited and PSL Engineering and Control Limited) won the $300m bid for the acquisition of the Ughelli Power Plant, one of the six power generation companies of the Power Holding Company of Nigeria (PHCN) being privatized by the Federal Government of Nigeria. Symbion Power was divested in September 2015.

On November 1, 2013, Transcorp Power officially took physical ownership of Ughelli Power Plc, the owner and operator of Ughelli Power Plant following a handover ceremony hosted by the Federal Government of Nigeria.

Naphthalenetetracarboxylic diimide. Naphthalenetetracarboxylic diimide (NTCDI) is a solid organic compound and one of the simplest naphthalenediimides (NDIs). NTCDI is produced from the parent naphthalene via an intermediate compound naphthalenetetracarboxylic dianhydride.

Properties

NTCDI is redox-active, forming stable radical anions at –1.10 V vs. Fc/Fc+ in Dichloromethane. Its ability to accept electrons reflects the presence of an extended conjugated ring system and the  electron withdrawing groups (carbonyl centers). NDI is used in supramolecular chemistry owing to its tendency to form charge-transfer complexes with crown ethers, e.g., to give rotaxanes and catenanes. As another consequence of their planar structure and electron-acceptor properties, NDIs intercalate into DNA. It is also suitable for fabrication of soft electronic devices.

Zhao Yufen. Zhao Yufen (; born 1948) is a Chinese chemist at the college of chemistry and chemical engineering at Xiamen University. She has been an outspoken critic of chemical plants. She was the youngest female member elected to the Chinese Academy of Sciences.

Biography 
Zhao was born in Qi County, Hebi, Henan, and moved to Taiwan in 1949 with her parents. Zhao graduated from National Tsing Hua University (Taiwan) in 1971, and received her Ph.D from State University of New York at Stony Brook in 1975. In 1979, she went on to become a researcher at the Institute of Chemistry, Chinese Academy of Sciences. She became a professor at Tsinghua University (Beijing) in 1988 and in 1991, was elected to the Chinese Academy of Sciences, then the youngest female academician.

In March 2007, Zhao created a petition to halt the construction of a chemical plant in Xiamen. Zhao was against the plant, which was going to produce paraxylene (PX), a carcinogenic petrochemical, due to health risks and pollution of the environment. She said that "As a project with a high risk of poisonous emissions and explosions, the project should not be located close to a city." She also started writing letters to propose a relocation of the plant to He Lefeng, the Party chief of Xiamen.  Months later, protesters used text messages to spread the word of a demonstration against the plant. Xiamen lawmakers voted overwhelmingly against the plant, which was located to Gulei Peninsula.

June 15, 2014, Zhao, as the head of the Academy Zhao Yufen of Xiamen University, along with BIOasis, signed on for the construction of a Phosphorus & Marine Science Research Center to be built at the Shandong International Biotechnology Park.

Zhao has work published in the Journal of the American Chemical Society, Journal of Organic Chemistry, Angewandte Chemie, Bioorganic & Medicinal Chemistry, Chemical Communications, Advanced Synthesis & Catalysis, and other journals.

Rambakan Oya Dam. The Rambakan Oya Dam is an embankment dam in Maha Oya, Eastern Province, Sri Lanka. The reservoir was designed and constructed by the Sri Lanka Mahaveli Authority and currently functions under the direction of the Ministry of Irrigation and Water Resources Management. It has been created by building an Earthen dam which is about 1,225m in length across the Mundeni Aru river.

The Rambakan Oya reservoir project is a multipurpose irrigation project which is commissioned to find a solution for the drinking water issue and irrigation problems in the area. It is the 10th zone of Mahaweli Development scheme and located bordering Badulla, Monaragala and Ampara districts.

History

Ancient time
There are archaeological evidences, those reveals about previous attempts to construct an irrigation tank here during the ancient time periods. According to them there are different legends and archaeological views on ancient construction of Rambakan Oya Reservoir. It is believed that construction of Rambaken Oya Reservoir was commenced by prince Giri Abaya who ruled the East, in third century, B.C. According to some other historical evidences it was commenced by Prince Saddhatissa (137-119 BC).

Ruins

There is a one-mile longed old earthen dam can be seen, near to the newly constructed dam. It was constructed between Gorikanda and Galkanda with rip rap, in high quality. Around 250 feet long dressed stones made to use for the twin Barrel Sluice are still remaining in surrounding. Any way there is no evidence to prove that the construction was completed or the reservoir was functioned.

Near to the old Sluice, a stone slab inscription belonging to 12th – 13th centuries can be seen and which identified as Rambakan Oya Slab Inscription. It describes that the stone canal was built by Liyana Nayakayan and Kanathkan Vahanse, who lived in the Gal Weta area.

Recent project
The recent project to develop the Rambakan Oya reservoir was commenced on 12 February 2007 and the opening ceremony was held on 20 July 2013 with the participation of then Sri Lanka President Mahinda Rajapaksa and Irrigation and Water Resources Management Minister.

Laboratory scissor jack. Laboratory scissor jacks are lifting stages for beakers, flasks, water baths, stirrer, or other lab tools used to elevate equipment height to the user's needs, usually around 5 to 20 cm. It consists of metal pieces connected together in a scissor-like shape between a top and a bottom platform. The metal pieces acting as an adjustable lift using the scissors mechanism (or pantograph) in changing its height and also can withstand a wide range of weight.

Manual lab jack 
The manual laboratory scissor jack works mechanically by having a central screw connected to the central piece of metal between two layers of crossing metal pieces. The screw performs the same task as screws in hydraulic car lift, supporting the metal pieces in withstanding the oppressing weight. Turning the screw increases and decreases the angle between the metal pieces, resulting in extension and contraction of the platform height.
