Sidi Rached Viaduct. The Sidi Rached Viaduct (), The Sidi Rached bridge is a road viaduct that crosses the Rhummel gorges and connects the Coudiat district (city center) to Constantine Train station. It was built in Constantine in French Algeria, between 1908 and 1912, by the engineer Aubin Eyraud, with the help of Paul Séjourné who designed the hangers and finished the construction. It was the tallest Concrete bridge in the world when it was built until .

Its length is 447 meters with 27 arches including one of 70 meters, the highest culminating at 107 meters. This was Aubin Eyraud's last work of art before he entered Oxford University as a professor. It was initiated by the then mayor Émile Morinaud, in the administrative framework of the department of Constantine at the time. It was inaugurated in 1912.

Poly Bridge (video game). Poly Bridge is a bridge-building simulation-puzzle game, developed by New Zealand–based indie studio Dry Cactus with music by Canadian composer Adrian Talens, where players build bridges for vehicles to cross. Poly Bridge was released for Microsoft Windows on July 12, 2016, iOS on June 13, 2017. Steel, wood, rope, and cable can be combined and used to strengthen a designed bridge and "hydraulics" are used to move pieces of the bridge. The game is made more difficult with the availability of different building materials of different prices. A sequel to the game titled Poly Bridge 2 was released on May 28, 2020 for Windows, macOS, and Linux.

Gameplay
The objective of the game is to build bridges to allow vehicles to cross them. That is done via 2D bridge model by creating a blueprint, and working with the materials which are given at use. Poly Bridge has a campaign mode with a series of scenarios that require different things to accomplish and introduce certain geographic features. In each level (more than 100 overall), there are two requirements: the building cost must come in under budget and the bridge has to be strong enough for a specific number of cars. There is also a sandbox mode that allows free building without restrictions, where the parameters can be set for creation. There is a variety of vehicles, ranging from motorcycles (fast and light) to dump trucks and cranes (slow and heavy). Since every vehicle has a different body and weight, that means longer cars may not be able to drive up steep slopes and the structure might need to adapt to the situation. The game also features obstacles such as jumps and boats, forcing the player to design their bridge creatively.  A badly built bridge will collapse under the weight of a crossing vehicle. The game includes a GIF generator, allowing players to capture certain moments while playing and share them online.

UBAKUSAT. UBAKUSAT was a Turkish nanosatellite that was developed by Istanbul Technical University. It was launched into space on board a Falcon-9 rocket in April 2018 and was deployed into its orbit from the International Space Station in May 2018. It was built as a technology demonstration and Earth observation satellite to provide voice communications for amateur radio stations around the world. It carried an experimental card, TAMSAT Simplesat, which allowed scientists to test its accuracy of measuring radiation from space. It was the fifth satellite to be built by students of Istanbul Technical University.

Development 
The contractual agreement covering the development and launching UBAKUSAT was signed between the Japanese government and the Istanbul Technical University on 8 September 2016, in Ankara. UBAKUSAT is a nanosatellite built by students of Istanbul Technical University's Faculty of Aeronautics and Astronautics, Space Systems Design and Test Lab (SSDTL). Technical support was provided by Turkey's Ministries of Transportation, Communication and Maritime in collaboration with the Japan Aerospace and Exploration Agency (JAXA) and Kyushu Institute of Technology. The satellite has an amateur radio and a linear transponder. UBAKUSAT's linear transponder is similar to the TURKSAT-3USAT satellite which was launched on 26 April 2013. UBAKUSAT is the fifth satellite to have been built by students of SSDTL. The first was ITUpSAT1 which was launched into low Earth orbit about  above Earth, on 23 September 2009 by a Polar Satellite Launch Vehicle rocket.

On February 23, 2018, UBAKUSAT was delivered to JAXA officials at Tsukuba Space Center in Ibaraki. The satellite then underwent several tests at the space centre to simulate conditions that will be faced in space.

Launch
On 2 April 2018, the satellite was carried on the International Space Station (ISS) on board a Falcon-9 rocket with help from the National Aeronautic and Space Administration (NASA). It was deployed from the space station into its orbit from the KIBO module on 11 May 2018. Its launch coincided with that of the 1KUNS-PF from Kenya and Irazú from Costa Rica. All three CubeSats carry amateur radio payloads with Irazú and 1KUNS-PF have telemetry beacons while UBAKUSAT carries a linear transponder for amateur radio. All three satellites were deployed into space from the Kibo module of the ISS by Japanese astronaut Norishige Kanai. UBAKUSAT was expected to orbit the Earth for a duration of between six and twelve months before de-orbiting.

Purpose  
UBAKUSAT was launched into space with the aim of providing voice communications for amateur radio stations around the world. The satellite had an experimental TAMSAT Simplesat card onboard which relayed data about space radiation to ground stations. The card was used in an experiment to assess its space radiation measuring technology.

Clyde Chambliss. Clyde Lee Chambliss Jr. (born April 16, 1969) is an American Republican politician who has served in the Alabama Senate from the 30th district since 2014. He completed his degree in Civil Engineering from the University of Alabama in 1992, after which he started his civil engineering firm.

Alabama abortion law 
In May 2019, he sponsored the Human Life Protection Act, which bans all abortions except in the case of endangerment to the mother’s health. Abortions in the cases of rape and incest are banned under the statute, which subjects those who perform abortions to a prison sentence of 10 to 99 years. When asked about the issue, Chambliss said: "When God creates the miracle of life inside a woman’s womb, it is not our place as human beings to extinguish that life."

The legislation only applied to zygotes or fertilized eggs that are inside the womb, not those used in fertility treatments. Chambliss explained the discrepancy, "The egg in the lab doesn’t apply. It’s not in a woman. She’s not pregnant."

Beijing BJ30. The Beijing BJ20/BJ30 is a compact CUV produced by BAIC Motor since 2015. It was first introduced in 2015 as the BAIC BJ20, and later in 2020, it received a major facelift and was renamed to Beijing BJ30. The second generation model was introduced in 2024.



BAIC BJ20 (2015-2020)

First introduced as the BAIC BJ20 concept car at the 2015 Shanghai Auto Show and previously the Beijing Auto Concept 500 that debuted on the Shanghai Auto Show in April 2013, the BAIC BJ20 production model was launched in August 2016, with the final production version of the Beijing Auto BJ20 debuting on the 2016 Chengdu Auto Show in China. The design of both the Concept 500 and the BJ20 were inspired by the Beijing BJ212, a classic Chinese off-road vehicle. 

The BAIC BJ20 is based on the same platform as the Senova X65, and is powered by a Mitsubishi-sourced ‘4A91T’ 1.5 liter turbo engine producing 147hp and 210nm. The only transmission offered is a six-speed manual gearbox and only front-wheel-drive is available. Pricing for the BJ20 starts at 96,800 yuan and ends at 139,800 yuan ($14.300 – 20.600).

Beijing BJ30 (first generation, 2021-2023)

Being essentially the facelift model of the BJ20, the BAIC BJ30 launched during the 2020 Guangzhou Auto Show in November 2020 is the first model to utilize Beijing Auto’s updated product naming system, using 2, 4, 6, 8-sequenced numbers for rugged off-roaders, and employing 3, 5, 7 and 9 monikers for urban off-road models. Compared to the BJ20, the BJ30 features a completely redesigned front and rear while still equipped with the same powertrain which is a 1.5-liter turbocharged gasoline engine producing 150 HP and 210 Nm (155 lb-ft) of torque, mated to a 6-speed manual transmission or a CVT.

Beijing BJ30 (second generation, 2024-present)

The second generation Beijing BJ30 is powered by a 1.5 liter A156T2H turbo engine produced by Beijing Automotive Powertrain Co., Ltd., producing a maximum power of 138 kilowatts paired to a 7-speed Dual-clutch transmission. A range extended electric version is also offered powered by the 1.5 liter A156T2H-H1 turbo engine produced by Beijing Automotive Powertrain Co., Ltd., specially tuned for REEV and mated a 2-speed Dedicated Hybrid Transmission (DHT).

The BJ30e was released in the Philippines in 2024 as the BAIC B30e Dune.
