Carbonyl dyes. Carbonyl dyes are dyes which comprise at least two conjugated carbonyl groups. Both anthraquinone dyes and indigo dyes belong to the group of carbonyl dyes. The most important natural dyes - indigo, Tyrian purple, alizarin and carmine - have this partial structure. The most important synthetic carbonyl dyes are based on anthraquinone.

The main advantages of carbonyl dyes are the possibility of reducing the carbonyl groups to water-soluble dienols (→Vat dyes), which is advantageous in industrial applications. On the other hand, by introducing suitable electron donating groups, the absorption maximum of the resulting dyes can be shifted to almost any region of the VIS spectrum.Reduction/Oxidation of carbonyl dyestuffs / examples: anthraquinone and indigo

Eagle Bluffs Conservation Area. Eagle Bluffs Conservation Area is a nature preserve and wetland in Boone County, Missouri. Located mainly in the Missouri River floodplain southwest of Columbia, Missouri and managed by the Missouri Department of Conservation, the wetlands are a refugee for migrating birds and home to several breeding pairs of bald eagles. The area is named after these eagles and the tall bluffs along the eastern edge of the Missouri River floodplain. Perche Creek flows through the refuge. McBaine, Missouri is located at the north entrance to the area. The Katy Trail State Park traverses the area.

The conservation area was created after the Great Flood of 1993 destroyed farmland. Water for the wetlands is provided by the Missouri River, but also, an innovative system to supply wastewater from the City of Columbia's treatment plant.

Rubber pollution. Rubber pollution, similar to plastic pollution, occurs in various environments, and originates from a variety of sources, ranging from the food industry processing chain to tire wear. Synthetic and natural rubber dust and fragments now occur in food, airborne as particulates in air pollution, hidden in the earth as soil pollution, and in waterways, lakes and the sea.

Causes

Tire wear is a major source of rubber pollution.
A concern is that, unlike exhaust emissions, vehicle tire wear pollution is not regulated.
Some devices are nonetheless being developed in an effort to reduce the amount of particulates coming from the tire and otherwise ending up in the atmosphere.
Although not immediately visible to the naked eye, tire dust makes up a significant portion of road debris.

Other sources can be artificial turf and rubber O-rings and seals.

Classification
Very fine rubber dust particles can depending on the classification be counted among microplastic (because rubber is just another polymer) or separately (because its constituent monomers, the required additives, and the type of chemical bond mesh is slightly different). In a similar vein, rubber pollution is often implicitly mentioned when plastic pollution is addressed.

6PPD-quinone, an antiozonant used in rubber tires, has been found to kill salmon when it accumulates into waterways from tire wear pollution.

List of Artemis missions. The Artemis program is a human spaceflight program by the United States. The Artemis program is intended to reestablish a human presence on the Moon for the first time since Apollo 17 in 1972; mid-term objectives include establishing an international expedition team, and a sustainable human presence on the Moon. Long-term objectives for Artemis are laying the foundations for the extraction of lunar resources, and eventually making crewed missions to Mars and beyond feasible.

To date, missions in the program are aimed at exploration of the Moon, including crewed and robotic exploration of the lunar surface. These explorations will be more focused towards areas such as the lunar poles and the far side of the moon. Three flights of the Orion Multi-Purpose Crew Vehicle are currently planned for launch in the Artemis program in the early 2020s, beginning with Artemis 1. Before Artemis was named, the flights were referred to as "Orion missions". Numerous supporting scientific and technology demonstration missions are planned for launch under the program's Commercial Lunar Payload Services (CLPS), in addition to planned and proposed uncrewed logistical missions to construct and resupply the Gateway and its expendable and reusable lunar landers in lunar orbit.

Main missions

Support missions

Technology demonstrations

Launched on 28 June 2022, the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment ("CAPSTONE") mission is a small (25 kg) technology-demonstration spacecraft designed to test a low-energy trans-lunar trajectories and to demonstrate the near-rectilinear halo orbit (NRHO) intended to support lunar polar missions.

Surface missions 

The Commercial Lunar Payload Services (CLPS) program will support the Artemis program by landing several small payloads focused on scouting for lunar resources, in situ resource utilization (ISRU) experiments and lunar science, in preparation for an extended human presence on the lunar surface.

Logistics missions 

Uncrewed missions to assemble and resupply the Gateway will be executed as part of the Artemis program.

Sound chip. A sound chip is an integrated circuit (chip) designed to produce audio signals through digital, analog or mixed-mode electronics. Sound chips are typically fabricated on metal–oxide–semiconductor (MOS) mixed-signal chips that process audio signals (analog and digital signals, for both analog and digital data). They normally contain audio components such as oscillators, envelope controllers, samplers, filters, amplifiers, and envelope generators.

History
A number of sound synthesis methods for electronically producing sound were devised during the late 20th century. These include programmable sound generators (PSG), wavetable synthesis, and frequency modulation synthesis (FM synthesis). Such sound chips were widely used in arcade game system boards, video game consoles, home computers and digital synthesizers.

Since the late-1990s, pulse-code modulation (PCM) sampling has been the standard for many sound chips, as used in the Intel High Definition Audio (IHDA) standard of 2004. The PCM sampling method is used in many mobile phones and sound cards for personal computers. This widespread use is part of the digital sound revolution that started in the 1980s.

Types
There are multiple types of sound chips, which are divided based on their use.

List of sound chips

Sound chips come in different forms and use a variety of techniques to generate audio signals. A list of all of the different sound chips produced by a certain company or manufacturer can be found in the List of sound chips article.

Applications
Sound chips are commonly used in various digital electronic devices, particularly personal computers (including sound cards and motherboards), video game systems (including arcade system boards and video game consoles), electronic musical instruments (including synthesizers, digital synthesizers and electronic keyboards), and digital telecommunications (including digital telephony, digital television, mobile phones and smartphones).

Leia Stirling. Leia Abigail Stirling (née Blumenthal) (born 1981) is the Charles Stark Draper Professor of Aeronautics at Massachusetts Institute of Technology, where she is the co-director of the human systems laboratory. She was elected an American Association for the Advancement of Science Leshner Leadership Institute Fellow in 2019.

Early life and education 
Stirling studied engineering at the University of Illinois at Urbana–Champaign, completing her master's degree in 2005. She earned her PhD at Massachusetts Institute of Technology in 2008. After graduating, Stirling completed a postdoctoral fellowship at the Boston Children's Hospital. She moved to the Wyss Institute for Biologically Inspired Engineering at Harvard University in 2009, where she worked as director of the Motion Capture Laboratory. There, she worked on robotic devices that could improve the function of the hands of people who had suffered from stroke or cerebral palsy.

Research and career 
Stirling joined Massachusetts Institute of Technology in 2013, where she co-directs the Human Systems Laboratory. She works on human–computer interaction and computational dynamics. She seeks to quantify the fluency of humans and machines in tightly coupled systems through the use of wearable sensors. She works on how to map wearable sensor information to a visible display. This information can help in the design of spacesuits, as well as helping people who have sensory disorders identify ways to interact with their environment. In the design of spacesuits, Stirling has studied whether haptic feedback could be used to help astronauts feel around their environments. Amongst these sensors, Stirling is interested in using them for the rehabilitation of stroke patients. Stirling believes that the development of high fidelity sensors will help rehabilitation survivors monitor their well-being and performance.

Stirling is interested in the use of exoskeletons for humans to enhance performance and reduce workplace injuries. Whilst exoskeletons have been proposed for use in the military, Stirling identified that they can reduce a soldier's response times. Stirling serves on the ASTM International F48 Committee on Exoskeletons and Exosuits.

In 2019, Stirling was selected as an American Association for the Advancement of Science Leshner Leadership Institute Fellow. She leads public engagement activities at the MIT Museum, including leading a wearable technology challenge for teachers and high school students.
