USS Elk River. USS LSM(R)-501 was the lead ship of the LSM(R)-501-class landing ship medium built in 1945 for service in World War II. She was later converted into a test range support ship and renamed USS Elk River (IX-501). Her namesake was a Minnesota town named Elk River.

Construction and career 
LSM(R)-501 was laid down on 24 March 1945 at Houston, Texas, by the Brown Shipbuilding Company. She was launched on 21 April 1945 and commissioned on 27 May 1945.

LSM(R)-501 served in the Pacific before and after the Japanese Surrender in September 1945. This vessel was designed to carry both shorter range guns and rocket launchers to deliver large volumes of fire in short periods. Decommissioned on 1 August 1946 at Astoria, the vessel was laid up in the reserve fleet Columbia River Group.

Renamed and redesignated USS Elk River (IX-501) on 1 October 1955, she was converted into a test range support ship at Avondale Shipyards and at San Francisco Bay Naval Shipyard.

In November 1967, she was underway off Long Beach, California in support of the SEALAB III Project.

In early 1982, Elk River began her installation of the Mk.14 CCSDS until the summer of that year. The ship later served as a barracks craft in October 1986.

Struck from the Naval Register in August 1999, Elk River was sunk as a target in February 2001.

A model of USS Elk River (LSM(R)-501, later IX-501) is on display in the Cold War Gallery, Building 70.

Samuel L. Higginbottom. Samuel L. Higginbottom (October 5, 1921 – November 13, 2016) was an American aerospace businessman. He served as president of Eastern Air Lines and Rolls-Royce North America and was chairman of the board of trustees of Columbia University.

Biography 
Higginbottom was born in North Lawrence, Ohio and graduated from Columbia University with a BS in civil engineering in 1943. After graduation, Higginbottom enrolled in the U.S. Army Air Corps and served in World War II, earning a Bronze Star Medal.

After the war, Higginbottom worked for Trans World Airlines, becoming senior vice president of engineering and maintenance. He then joined Eastern Airlines, where he served as president, CEO, and a member of the board of directors from 1970 to 1973. As chief executive, he was responsible for enlarging the airlines' engine service center as well as its business operations during the early 70s.

From 1974 to his retirement in 1986, Higginbottom was chairman, President and chief executive officer of Rolls-Royce North America. In 1982, he was appointed chairman of the board of trustees of Columbia University, of which he had been a trustee since 1978, and served until 1989. As chairman of the trustees, he was criticized for refusing to divest from South Africa.

He was made an honorary Commander of the British Empire by Elizabeth II for his work with Rolls-Royce.

Higginbottom retired to Miami, where he remained active in the business world, serving as director of HEICO from 1989 until his death in 2016.

Shearing (textiles). Shearing is a kind of mechanical finish in which the appearance of the fabric is enhanced by cutting the loops or raised surface to a uniform and even height. The machine may have a spiral blade similar to a  reel lawn mower. A shearing machine can cut the loop or the pile to a desired level. Shearing was most commonly used to make woollens and worsted materials. It was a part of dry finishing of woollen and worsted goods. Previously, shearing was also a component of gigging or napping; when partially produced goods were exposed to shear in order to improve the impact of gigging or napping, the process was referred to as "cropping".

History
Most of the Medieval clothing and textiles were processed and finished manually. The finishing of English Woollens includes shearing. Shearmen were skilled artisans who used to shear the fabric by hand. Shearman's job was to nap the cloth manually, using teasels and shears to trim the pile. A silky and smooth feeling was produced by the gradual lowering of the nap. The process was referred to as "dry shearing". It was formerly an expensive and lengthy process compared to the "wet shearing" that was a rough process. During the early 17th century, two shearmen spent two weeks dry shearing three broadcloths.

Shearing machine 

A shearing machine is a machine equipped with shearing cylinder, ledger blade, fluff exhaust, and joint seam sensors. The machine operates similarly to a lawn mower. Seam joint sensors prevent seams from being cut.

Advantages 
Moleskin and velvet are shorn materials in which pile is cut to a certain level. Other than imparting an aesthetic finish, shearing was also used to cut certain deformations, unwanted surface defects such as protruding yarns. In the case of polyester blends, a shearing machine is also useful for removing surface beads or naps of dyed fibers.

Sculptured effect
Shearing can also create certain effects, sculpted effects are achieved by flattening sections of the pile with an engraved roller and then the remaining upright sections are shorn off. Flattened portions are then steamed and raised.

Embossed velvet and plush fabric are created by weaving the pile high and shearing it to various levels, or by pressing a portion of the pile flat.

Bara Pulah Bridge. The Bara Pulah Bridge or Barapullah Bridge is a busy road-passing in Delhi, India, near Humayun's Tomb and Khan-i-Khana's Tomb. It is surrounded by the fruit and vegetable market behind the Nizamuddin railway station. Due to the increasing population and traffic problems, the government announced a new Barapullah Elevated Road project during the Delhi Commonwealth Games. The new overpass bridge has marginally solved the traffic problems, but has overshadowed the historic bridge which is now almost invisible and overrun by squatters. The BaraPullah Bridge is a monument of national importance and protected by the Archaeological Survey of India (ASI).

History 
The Barapullah bridge was built by Mihr Banu Agha nearly 400 years ago. According to historians, the bridge was built under Jahangir's rule and personally commissioned by him. The Mughals used the bridge to cross the Yamuna river to reach Nizamuddin Dargah and Humayun's Tomb while returning from Agra. In 1628 the road between the bridge and Humayun's Tomb was a wide tree-lined path and was considered the most beautiful bridge of Delhi.

In August 2024, the ASI started restoration of the bridge. They removed silt and garbage collected on the neglected bridge and aim to restore it as a pedestrian bridge.

Architecture 
The bridge structure has 12 piers and 11 arches, and it is  in length.

Memve'ele Hydroelectric Power Station. Memve'ele Hydroelectric Power Station is a 211 megawatt hydroelectric power station in Cameroon. Construction of this dam began in April 2012 and the dam produced its first 80 megawatts in April 2019. Full commercial operations are expected to begin once the 225 kiloVolt high voltage transmission line to Yaounde is completed.

Location
The power station is located at the village of Nyabissan, in Ntem Valey Département, in the South Region of Cameroon, across the Ntem River. Nyabissan is located approximately , by road, southwest of Ebolowa, the nearest large town.

Nyabissan is located approximately , by road, southwest of Yaoundé, Cameroon's capital and second largest city.

Overview
The development of this power station was originally led by a consortium comprising Globeleq and Sud Energie,
based in the United Kingdom. In May 2009, that consortium backed out of the deal. That same year, Sinohydro, the Chinese state-owned construction company took over the development rights, as engineering, procurement and construction (EPC) contractor.

According to online reports, the construction phase began in earnest after the EPC contract with Sinohydro was executed in April 2012. The design calls for an earth fill dam measuring  high, creating a reservoir lake containing  of water.

The design also calls for a 225kV high voltage evacuation line from the power station to Yaoundé, where most of the generated energy is destined. The installation of three 225kV/90kV transformers at Ebolowa, Nkoumou and Ahala, is part of the design.

Construction costs
Due to multiple delays, the cost for this project has kept increasing over time. In May 2009, the cost estimates were €556 million (approx. US$795 million). As of August 2021, total cost for all the project components totaled US$831.6 million (approx. €727.2 million). As of December 2021, €5 million (approx. US$5.7 million) was still needed to compensate landowners, in order to allow the completion of the high voltage electricity evacuation line.

Funding
The table below illustrates the funding sources for the power station, evacuation line and associated infrastructure, including electricity substations.

Operations
The energy generated at this power station is sold to Eneo Cameroon SA, the national electricity utility company.
