Victory marking. A victory marking (also called a victory mark, kill marking, or kill mark, or mission symbol) is a symbol applied in stencil or decal to the side of a military aircraft, ship or ground vehicle to denote a victory achieved by the pilot or crew against an aerial target. The use of victory markings originated during World War I, burgeoned during World War II and frequently took the form of the roundel or national flag of the nationality of the military target defeated. Sometimes damaged targets also included, but the mark will be slightly different to distinguish them from those targets that are destroyed. These enemy targets can be planes, helicopters, trains, ships and sea mines in World War II, which later also include cruise missiles and drones in subsequent conflicts. The manner of destruction that qualify for a victory mark also varies, from bombs and cannons by planes, deck guns by ships to torpedoes by submarines.

In 2012, a German Eurofighter was spotted with a kill mark denoting a simulated victory over a U.S. Air Force F-22 Raptor, achieved in a dogfight during a training exercise.

In the United States Air Force, as of 2010, victory markings are applied in the form of six inch green stars set within a black border with the type of aircraft defeated stencilled inside the star in white lettering.

In the Russo-Ukrainian War, Ukrainian anti-air defenses such as Flakpanzer Gepards and Patriot Missile systems are decorated with victory markings for successfully shooting down Russian aerial targets, missiles and Iranian Shahed drones.

Mission symbol 
Victory marks have been applied to aircraft for reasons other than aerial victories.  During the period of its use for astronaut recovery, the U.S. Navy's Helicopter 66 bore victory marks showing a space capsule silhouette, with one mark added for each recovery in which it participated.

Pentanenitrile. Pentanenitrile, valeronitrile or butyl cyanide is a nitrile with the formula C4H9CN. This can be written BuCN, with Bu representing an n-butyl (linear butyl group).

Production
Pentanenitrile can be produced by heating 1-chlorobutane with sodium cyanide in dimethyl sulfoxide. This reaction takes about 20 minutes, keeping the temperature below 160 °C. The yield is about 93%.

Another way to get the substance is by heating valeraldehyde with hydroxylamine.

Pentanenitrile is contained in bone oil.

Properties
The pentanenitrile molecule is flexible and can adopt a number of different conformers, so that it will naturally be a mixture. These conformers are called anti-anti (30%), anti-gauche (46%), gauche-anti, gauche-gauche-cis, and gauche-gauche-trans.

Biology
Pentanenitrile is toxic to animals, and produces its action by the liberation of cyanide by cytochrome P450. The cyanide is detoxified and excreted in urine as thiocyanate.

Pentanenitrile is found in Brassica species and varieties such as broccoli.

Pentanenitrile is hydrolyzed to valeric acid by the fungi Gibberella intermedia, Fusarium oxysporum, and Aspergillus niger in which it induces production of the nitrilase enzyme.

1KUNS-PF. 1KUNS-PF (1st Kenyan University NanoSatellite-Precursor Flight) was the first Kenyan-owned satellite. The cubesat was developed and assembled by the University of Nairobi for the Kenya Space Agency, with technical support provided by Japan's Aerospace Exploration Agency. The spacecraft was deployed from the International Space Station after being launched by a SpaceX Falcon 9 rocket.

Background  
The idea to launch a Kenyan-built satellite began in September 2015 with the planning and design of the space module. Financial support was obtained for the project when the University of Nairobi won a competitive grant from the United Nations Office for Outer Space Affairs (UNOOSA) in 2016. The University of Nairobi was the first institution to benefit from a joint project between the United Nations and JAXA. The satellite was given the acronym 1KUNS-PF, which stands for which First Kenya University Nano Satellite-Precursor Flight. External technical support was provided by Sapienza University along with two Italian companies. The cost of the programme was roughly one million dollars. The satellite orbited  above the Earth.

Launch and purpose 
On 2 April 2018, the satellite was carried to the International Space Station on board the SpaceX CRS-14 mission which launched on a Falcon 9 rocket with help from the National Aeronautic and Space Administration. It was deployed from the space station into orbit from the Kibō module on 11 May 2018. Its signal was successfully received from a ground station in Rome by the students of Sapienza University. Its launch was the third for an African country after GhanaSat-1 and Nigeria EduSat-1, which went into service in 2017. In addition to 1KUNS-PF two other nano satellites, Ubakusat and Proyecto Irazú were also on board the Falcon-9 rocket to the ISS. All three satellites were deployed into space from the ISS by Japanese astronaut Norishige Kanai.

The 1KUNS-PF was a 1 unit cubesat. It was an experimental cubesat, with the main mission being to create awareness to the locals on the benefits of space uses. On board the cubesat, there were camera payloads, which were used to take mapping images of Kenya and other East Africa countries within the vicinity of its orbit. The cubesat was designed to have a lifespan of one year and its operations were within the UN space use mitigation measures. 1KUNS-PF deorbited in June 2020.

Irazú (satellite). Irazú was the first Costa Rican satellite to be launched into space. The nanosatellite was launched into space on 2 April 2018, on board a Falcon 9 rocket headed for the International Space Station. It was expected to orbit the Earth for six months with the function of monitoring carbon, humidity, and temperature levels in Costa Rican forests. Funds for the launch of satellite were provided, in a significant part, through a Kickstarter crowdfunding campaign.

Background 
The design, development, and financing of the Irazú satellite involved the Central American Association for Aeronautics (ACAE), based in Costa Rica, and engineers from the Costa Rica Institute of Technology. Fifteen professors and students from Costa Rica Institute of Technology and from the National Training Institute worked on the project. 

The 10-centimeter cube "nano" satellite monitored temperature, humidity, and carbon dioxide fixation with the purpose of climate change analysis. Building the satellite from its individual component took six months and required an additional six months for testing. After the initial testing period, Irazú was sent to Japan where it was further tested at the Kyushu Institute of Technology. It was later sent to the Japan Aerospace Exploration Agency for onward delivery to NASA. 

The total cost of the project was US$500,000 with much of the money coming from ACAE. The Costa Rica Institute of Technology was tasked to provide the final $75,000 needed to complete the last stages of construction, testing and deployment into space. The institute turned to crowdfunding experts from Ernst & Young to raise the expected amount. Through Kickstarter, about 800 donors from all over the world helped to raise the funds needed.

Launch 
On 2 April 2018, the satellite was carried to the International Space Station (ISS) on board a Falcon 9 rocket with help from NASA. It was deployed from the space station into its orbit from the KIBO satellite deployment module on 11 May 2018. Its launch coincided with two other satellites namely Ubakusat and 1KUNS-PF. All three satellites were deployed into space from the ISS by Japanese astronaut Norishige Kanai through the Kibo module. The satellite orbited the Earth at a height of about  above the Earth and was expected to operate for six months.

Communication 
Irazú communicated with two Earth stations: the experimental station at San Carlos, and the monitoring station on the central Campus of Costa Rica Institute of Technology in Cartago. At the monitoring station, information was relayed from space concerning the level of tree growth in the country. The data was used to determine the approximate carbon fixation rate of Costa Rican forests.

Sinéad Griffin. Sinéad Majella Griffin (born July 20, 1986) is an Irish physicist working at Lawrence Berkeley National Laboratory on condensed matter physics and materials science. She won the 2017 Swiss Physical Society Award in General Physics.

Early life 
Griffin was born in 1986 in Rush, Dublin, Ireland.

Education 
Griffin studied physics at Trinity College, Dublin, graduating in 2008 with a bachelor's degree in theoretical physics. She moved to Imperial College London for her master's studies, working with Ray Rivers on topological defects in condensed matter and cosmology. She worked at the University of California, Santa Barbara, for her doctoral studies, studying superconductors and spintronics with Nicola Spaldin. When Nicola Spaldin joined ETH Zurich, Griffin accompanied her, earning a PhD, in 2014 looking at the Hubbard model for hexagonal manganites. During her PhD she tested the Kibble–Zurek mechanism in YMnO3. She won the 2015 Materials and Processes (MaP) Award for the best interdisciplinary thesis at ETH Zurich.

Career 
In 2015 Griffin joined Jeffrey Neaton's laboratory at Lawrence Berkeley National Laboratory. She recognized that multiferroic hexagonal manganites exhibited the same symmetry as those proposed shortly after the Big Bang, testing phenomena that occur on galactic scales with those that occur in a laboratory. Her work explored symmetry-breaking conditions that lead to topological defects. Griffin has also worked on materials for high-energy physics experiments.

In 2023, she won the Early Career Scientist Prize in Computational Physics from the International Union of Pure and Applied Physics. In the same year, Griffin published an arXiv preprint, presenting density functional theory augmented with a on-site Hubbard-like model (i.e., DFT+U) calculations  of Cu-substituted lead phosphate apatite (i.e., suspected structure of LK-99), identifying correlated isolated flat bands at the Fermi level, a debated signature of superconductors. Per the author, this work did not show that LK-99 is a superconductor at room temperature, but suggested the possibility of a room temperature superconductivity. Her findings propose a simplified two-band model for understanding this behavior in LK-99, and potentially other superconductors. Similar theory preprints by other academics and researchers did not entirely agree with Griffin's results.

XOD (programming language). XOD is a visual programming language for microcontrollers, started in 2016. As a supported platform, XOD started with Arduino boards compatibility and Raspberry Pi. It is free and open-source software released under the GNU Affero General Public License, version 3.0.

Basics 
The basic elements of XOD programming are nodes. XOD is based on functional reactive programming principles and provides graphical flow-based application programming interface. XOD can compile a native machine code for the low-ended controllers. A node is a block that represents either some physical device like a sensor, motor, or relay, or some operation such as addition, comparison, or text concatenation. XOD is also able to let the user build up some missing node using other nodes, without switching to textual programming.

Analogs 
Node-RED and NoFlo are the closest analogs of XOD.
