Air Commando Rifle Regiments. The air commando rifle regiments are specialized regiments belonging to the Algerian Air Force.

History and service
Air commando rifle units dates back to the 1970s, when a special air component was proposed to President Houari Boumediène. In 1990, the first air commando riflemen began training at the National School of Air Technology in Blida. Non-commissioned Algerian Air Force officers also trained there. Commando riflemen training was later transferred to the Air Rifle Training Centre in Mechria and in 1992, the first regiments appeared in the Air Force under Major General Benslimani. This followed the release of the first promotion of air rifle commandos.

As of 2021, the Algerian Air Force has six regiments of air fusilier commandos and battalions of air fusiliers to protect airbases across different military regions. Now, initial training, which involves parachuting, weapons handling, close combat techniques, and shooting from helicopters, is held at the Fusiliers Commandos de l'Air in Mechria. Following training, they are certified; soldiers then undergo additional selection, training, and education within their regiments.

The 772nd Regiment is the only special forces regiment and is based in Aïn Oussera, though the 782nd regiment, located in Laghouat, is also considered an elite unit. The air commandos also have specialized units such as dog units. These spearheaded the Air Force and were heavily involved in the fight against terrorism during the Black Decade, particularly in the mountains. They are still heavily involved in these operations today. Air commando rifle regiments generally work on reconnaissance missions, human intelligence, air support, search and rescue operations, helicopter-borne shooting, hostage release, neutralization, sabotage, seizure and reinstatement of airport areas, recognition or destruction of targets, and combat search and rescue. Police dog teams search for explosive materials or weapons.

Armament and equipment
Air commando rifle regiments use a number of guns and assault weapons, including handguns (Glock 17s and Caracal pistols), assault rifles (AKMs and AKMS), machine guns (RPD machine guns, RPKs, and PK machine guns), precision rifles (Zastava M93 Black Arrow and Dragunov sniper rifles), shotguns (SR202Ps), and grenade launchers (RPG-7s). They are issued a SPECTRA helmet, protection glasses, an Algerian Army lattice, an Algerian Air Force lattice sata, gloves, knee and elbow pads, a bullet-proof vest, a tactical vest, a thigh or hip holster, and a balaclava. Some soldiers use night vision binoculars; thermal, infrared binoculars, sights, lasers, and lamps. Air commando rifle regiments typically use Air Force airplanes and Mil Mi-17s in the air and Mercedes-Benz G Class, Zetros, Unimogs, and SNVI M120s on the ground.

1,6-Hexanediol diacrylate. 1,6-Hexanediol diacrylate (HDDA or HDODA) is a difunctional acrylate ester monomer used in the manufacture of polymers. It is particularly useful for use in ultraviolet light cure applications. Furthermore, it is also used in adhesives, sealants, alkyd coatings, elastomers, photopolymers, and inks for improved adhesion, hardness, abrasion and heat resistance. Like other acrylate monomers it is usually supplied with a radical inhibitor such as hydroquinone added.

Preparation 
The material is prepared by acid-catalyzed esterification of 1,6-hexanediol with acrylic acid.

Other uses

As the molecule has acrylic functionality, it is capable of undergoing the Michael reaction with an amine. This allows it use in epoxy chemistry where its use speeds up the cure time considerably.

ASUSat. ASUSat (Arizona State University Satellite, also known as ASU-OSCAR 37) was a U.S. amateur radio satellite that was developed and built for educational purposes by students at Arizona State University. It was equipped with two digital cameras for tracking changes to Earth's coasts and forests.

ASUSat was launched on January 27, 2000, along with JAWSAT with a Minotaur I rocket from Vandenberg Air Force Base, Lompoc, California. ASUSat was received 50 minutes after the start in South Africa, later also in New Zealand and the United States. During two overflights over Arizona, Arizona State University students were able to receive and control the satellite remotely. A problem with the power supply was reported on the third pass, 14 hours after take-off. The solar cells did not provide any electrical energy, so the batteries were exhausted shortly afterwards.

Hydrodimerization. Hydrodimerization is an organic reaction that couples two alkenes to give a symmetrical hydrocarbon.  The reaction is often implemented electrochemically; in that case the reaction is called electrodimerization. The reaction can also be induced with samarium diiodide, a one-electron reductant.

Hydrodimerization is the basis of the Monsanto adiponitrile synthesis:
2CH2=CHCN  +  2e−  + 2H+   →  NCCH2CH2CH2CH2CN

The reaction applies to a number electrophilic alkenes (Michael acceptors).

DR2800 series. The DR2800 series is a series of diesel multiple unit trains operated by the Taiwan Railways Administration as Tze-chiang limited express on non-electrified mainlines. They were originally built by Tokyu Car Corporation of Japan in 1982 for the Taiwan Railways Administration to provide better service on the eastern mainline of Taiwan.

In early 1980s, the North-link line was completed, the Yilan line was expanded to double track, and the gauge of Taitung line was changed to 1067 mm. In response to the demand for air-conditioned express trains in eastern Taiwan, Taiwan Railways Administration ordered 10 sets of  diesel multiple unit trains from Tokyu Car. These train sets were heavily specialized under license from Budd, and each set consists of 2 power driving cars and a trailer. Each power driving car (designated as DR2800s) was equipped with a Cummins NT855-R4 diesel engine producing  to move the train. The trailer (designated as DR2850s) has a diesel engine to provide head-end power for the entire three-car set. Each power driving car only has a cab at one end and two power driving cars bracket a trailer in a standard set. To prevent dependency on the trailer's engine for cooling, the cooling fans of the driver cars are driven hydraulically instead of electrically. Besides, the DR2800 series is the first series of diesel railcars of Taiwan Railways Administration equipped with bogies containing air suspension.

The DR2800 series operated as Tze-chiang limited express between Taipei and Hualien on June 1, 1982. With a top speed of  and air-conditioning, the demand was so high that Taiwan Railways Administration  ordered another 5 sets (15 cars) in 1984. 

The interior was refurbished between 2001 and 2002. The original Cummins NT855R-4 diesel engines were replaced by Cummins NTA855-R1 in 2002 and 2003, and the total output of a set increased to . 

DR2800 series mainly operated as Tze-chiang limited express on the eastern mainline (including Yilan line, North-link line, and Taitung line) and South-link line. In 1991 it even ran on the west line to provide more seats during Chinese New Year. Nowadays all 15 sets are still in service. But owing to the greater gap between the platform and the car, DR2800 series now runs on Yilan line and North-link line only.

Kuwait Space Rocket. The Kuwait Space Rocket (KSR), is a Kuwaiti project to build and launch the first suborbital liquid bi-propellant rocket in Arabia. The project is intended to be the first step towards starting a space industry in the country and a launch service provider in the GCC region. The project is divided into two phases with two separate vehicles. An initial testing phase with KSR-1 as a test vehicle capable of reaching an altitude of  and a more expansive suborbital test phase with the KSR-2 planned to fly to an altitude of . in May 16 Ambition-1 launched but had a malfunction with the parachute and crashed in free fall.

History 
The project began in January 2018 for conceptual design and planning. The team started the fabrication of KSR-1 in early 2019, and as of January 2020, KSR-1 was fully built.

KSR-1 
KSR-1 is a vertically-launched single stage rocket. It uses a liquid bi-propellant rocket engine burning methanol as fuel and nitrous oxide as the oxidizer. KSR-1 is intended to be a test vehicle for the development of KSR-2, the goal of which is to reach space. As such, all the major components and technologies that are expected to be used in KSR-2 are present in KSR-1. The main components of KSR 1 are the engine—consisting of the injector, nozzle, and cooling jacket— with fuel and oxidizer tanks, a nitrogen gas tank, and various valves and pressure regulators.

KSR-1 Development Process

Engine Fabrication 

The KSR-1 engine was built locally in Kuwait and it utilizes a pressure fed cycle. The engine utilizes the nitrous not only as an oxidizer but as a cooling agent, that flows around the nozzle and back into the injector again.

Cold Flow Testing 
The KSR team performed a cold flow testing in October 2019 to verify the engine's flow rate and plumbing.

Static Testing 

KSR performed a static testing of the Injector in November 2019.

Structural Assembly 
The KSR-1 was fully assembled and presented at the Kuwait Aviation Show 2020.

KSR-2 
KSR-2 is a planned liquid bi-propellant suborbital launch vehicle. It is the second installment of the KSR Rocket Family, composed of a single stage, fueled by nitrous oxide and methanol. KSR-2 will have a total length of 4 m, a diameter of 0.4 m and a total mass of 591 kg, its apogee will be around 100 km.
