Elliott Bridge, Sirajganj. Elliott Bridge (locally known as Boropool) is an old bridge over the Boral River in Sirajganj, north-western Bangladesh. The pillarless bridge is named after the Lieutenant Governor named Charles Alfred Elliott. It cost 45 thousand takas to make it. It is one of the major attractions of Sirajganj city.

History
The river Boral or Katakhali, which flows through the town named Sirajganj, divides the city into two parts, East and West. Due to its connection with the river Jamuna, the flow of water in this Katakhali was much higher. So in 1892, the then sub-divisional officer Bitson Bell, planned to build a bridge to solve the traffic problem between the two banks.

The Hartland Company built the bridge, designed by Stuart Hartland who was a British engineer. Charles Alfred Elliott, the then Lieutenant Governor of Bengal laid its foundation stone on 6 August 1892. The bridge, named Elliott Bridge, is named after him. The bridge has since been renovated several times.

Funding
It cost Tk 45,000 to build the bridge at that time. Magistrate of Pabna District Julius gave a grant of Tk 15,000 from the district board. The rest of the money was collected from donations from local zamindars and rich people.

Architecture
It is an arch bridge without pillars. The entire structure of the 160 feet long and 18 feet wide bridge is made of steel. Above it was a wooden deck. As they were destroyed, concrete was used later.

The height of the bridge is 30 feet. The bridge was raised and built without pillars so as not to disrupt the movement of large cargo ships plying the Katakhali river. Apart from this, standing on the bridge so that the view of Sirajganj city could be seen was also another reason for building the bridge.

Current status
The bridge is one of the sights of Sirajganj city. In 1962, the construction of the Sirajganj City Protection Dam on the Jamuna made the mouth of a sluice gate at the Baitara end of the Katakhali River and the other mouth closed. In 2019, the re-excavation of the river happened by Sirajganj Water Development Board. The river Jamuna was then connected to Baitara through a switch gate. As a result, water flows in the river and the bridge regains its beauty. Heavy vehicles are not allowed to cross the bridge to protect it.

Advanced Research and Invention Agency Act 2022. The Advanced Research and Invention Agency Act 2022 (c. 4) is an act of Parliament of the United Kingdom that creates the Advanced Research and Invention Agency. It was introduced in the House of Commons by the Secretary of State for Business, Energy and Industrial Strategy Kwasi Kwarteng on 2 March 2021.

Background 

The government have said that the Advanced Research and Invention Agency (ARIA) is an attempt to emulate the United States' Advanced Research Projects Agency (ARPA) and similar governmental agencies such as in Germany and Japan.

Former adviser to Prime Minister Boris Johnson, Dominic Cummings, is credited with inspiring the Government to push forward with this policy. Cummings was called in front of the Science and Technology Select Committee's inquiry into the plans for ARIA.

Notable amendments

Purpose of ARIA 
The SNP's Business spokesperson Stephen Flynn and Labour's Shadow Minister for Science, Research and Digital Chi Onwurah pushed an amendment to a division that would have changed the primary objective of ARIA to focus on net-zero technologies. All parties supported the amendment except the Conservatives and the DUP. The amendments failed.

Freedom of information 
Labour also put forward an amendment that would have put ARIA under the scope of the Freedom of Information Act 2000 as the Act has an exemption. This amendment also failed.

Diglycidyl aniline. Diglycidyl aniline is an aromatic organic chemical in the glycidyl compound family. It is used to reduce the viscosity of epoxy resin systems. It has the empirical formula C12H15NO2 and the IUPAC name is N,N-bis(oxiran-2-ylmethyl)aniline. The CAS number is 2095-06-9. It is REACH registered in Europe with the EC number 218-259-5. A key use is in the viscosity reduction of epoxy resin systems functioning as a reactive diluent.

Alternative names
 Diglycidylaniline
 N,N-Diglycidylaniline
 N,N-bis(oxiran-2-ylmethyl)aniline
 Oxiranemethanamine, N-(oxiranylmethyl)-N-phenyl-
 Bis(epoxypropyl)phenylamine
 Bis(2,3-epoxypropyl)aniline
 Bis(oxiranylmethyl)benzenamine
 Benzenamine, bis(oxiranylmethyl)-

Manufacture and synthesis
Many glycidyl ethers are manufactured by addition of epichlorohydrin to a species with the aid of a Lewis acid as catalyst to form a halohydrin. This process is followed by washing with sodium hydroxide in a dehydrochlorination reaction. This diglycidyl compound being basic and nitrogen based, does not need this type of catalyst. One of the quality control tests would involve measuring the Epoxy value by determination of the epoxy equivalent weight in addition to viscosity.

Uses
The use of the diluent in epoxy systems affects the mechanical properties and microstructure of epoxy resins. The kinetics of cure of this Diglycidyl amine with epoxy resin networks have been studied. It has also been used to synthesize other materials including ion-exchange resins.

Toxicity
The toxicity profile has been studied and published.

Gelt Bridge. The Gelt Bridge or Gelt Viaduct (also known as Middle Gelt Bridge) is a skew arch railway viaduct in the parish of Hayton, east of Carlisle in Cumbria, north west England. Built from 1832, it is one of the earliest and largest skew bridges in Britain. It is a Grade II* listed building.

Background
The idea of linking Newcastle upon Tyne on England's east coast with Carlisle on the west dates back to at least the 1770s, when proposals were tabled for a canal. The prospectus for the Newcastle & Carlisle Railway was published in 1825 and construction work began in 1829 under the supervision of Francis Giles. The line was one of the earliest mainline railways and Britain's first major east-west line.

Giles was the consulting engineer for the entire line but was also directly responsible for the principal works at the western end, which presented some of the greatest engineering challenges on the route, including the Gelt Bridge and the Corby Bridge (or Wetheral Viaduct) and Corby Viaduct some five miles closer to Carlisle.

Design
The bridge consists of three skew arches, each with a span of , standing on two rusticated pillars. It carries the railway  over the River Gelt in a deep  but narrow gorge. The bridge has a skew angle of 27 degrees. It is built from rusticated red sandstone, with smoothed voussoirs and V-shaped joints. An iron railing forms the bridge parapet. A plaque is built into each of the abutments; one reads "Gelt Bridge: Francis Giles Engineer, John McKay Builder, MDCCCXXXII; MDCCCXXXV"; The other has the same inscription in Latin.

History
The bridge was designed by Francis Giles, engineer to the Newcastle & Carlisle Railway, and built by the contractor, John McKay. Construction began in 1832 and the bridge was completed by 1835, making it one of the earliest railway skew bridges and one of the largest of its era. The viaduct is still in use, carrying the modern Tyne Valley line. It is a grade II* listed building.
