The sounds of STEAM


By Jennifer Tidball

If a Kansas State 1xbet online games login researchermakes a discovery and no one is around to hear it, does it make a sound?

Of course it does. We collected the sound bites to prove it.

The perception of sound is more than a philosophical thought experiment. Sound plays an active role inSTEAM — science, technology, engineering, art and mathematics — 1xbet online games login at Kansas State University. These 1xbet online games login noises come from laboratories, studios, industrial plants and the great outdoors.

This interactive text describes 1xbet online games login projects at Kansas State University and the sounds associated with them.

Listen to the multidisciplinary symphony of 1xbet online games login in science, technology, engineering, art and mathematics.

Nuclear noises

When the countdown reaches zero, theTriga Mark II nuclear reactor facility executes its special capability: a reactor pulse. With a loud “ca-chunk,” the reactor ejects a control rod using air pressure, which causes the power to increase by a factor of 100 million in 0.01 seconds and then rapidly return to low power. Six seconds later, a “clank” means the rod has fallen back into place in the core.

The special capability produces a large amount of neutron flux in a short period of time, which can be used for analyzing materials and developing radiation detectors, said Jeff Geuther, nuclear reactor manager.

The nuclear reactor, part of the mechanical and nuclear engineering department, has other important 1xbet online games login capabilities and also supports academic and education programs, industrial service and outreach.

The Flint Hills are alive with the sounds of ... bison, bugs, birds and burning.

Those sounds are part of 1xbet online games login atthe Konza Prairie Biological Station, an 8,600-acre native tallgrass prairie jointly owned by Kansas State University and The Nature Conservancy. The Konza Prairie — nestled in the Flint Hills just south of Manhattan — provides an outdoor laboratory for long-term ecological 1xbet online games login , education and prairie conservation.

1xbet online games login at the Konza Prairie includes watershed-level experiments focused on tallgrass prairie ecosystems and the effects of fire, bison grazing and cattle grazing, as well as other basic biological 1xbet online games login . A recent study found that more frequent burnings in the Flint Hills are needed to keep the tallgrass prairie ecosystem from transitioning to woodland, said John Briggs, director of the Konza Prairie.

Birds of a feather make sounds together. Aflock of flamingos can be especially noisy. 1xbet online games login flapping of feathered wings to low grunts and higher-pitched honking, flamingos are social birds.

Researchers with the 1xbet online games login ’s Veterinary Health Center are improving the health of the pink birds. James Carpenter, professor of zoological medicine, and veterinary medicine interns and students are collaborating with Manhattan’s Sunset Zoo to study the zoo’s Caribbean flamingo flock. The researchers are determining the proper dosages for antibiotics and anti-inflammatory drugs that can treat disease in this species. They also have tested a vaccine that prevents West Nile virus infections, which can be fatal to flamingos and other birds.

Flamingos are also susceptible to eye infections, and Carpenter and the Veterinary Health 1xbet online games login ophthalmologists have performed ocular examinations in flamingos to develop better diagnostic procedures and earlytreatment options.

Feeding sounds

FeedingSounds


1xbet online games login whirling of the pellet-makingskip touch to the pouring of corn and other grains, the university’s O.H. Kruse Feed Technology Innovation Center is full of the sounds of industrial 1xbet online games login .

The center includes a modern, automated 5-ton per-hour production and teaching feed mill and a biosafety level-2 teaching and 1xbet online games login feed mill. The center is the home of the university’s feed science and management program — one of only two such university programs in the country, said Charles Stark, director of the center.

Several times a week, the mill receives grain from delivery trucks. Researchers grind the grain, weigh it and then mix it to make various feeds. Finished feed goes to the cattle, swine and other animals in Kansas State University units and also is used for 1xbet online games login and industry projects.

Listen to the day-to- day sounds at the feed mill.

Taking off

TakingOff


Unmanned aircraft systems, or UAS, are a common sound at the Kansas State 1xbet online games login Polytechnic Campus. After a few start-up beeps and noises, the whirling of motors and blades begins and the UAS is ready for takeoff.

Kansas State Polytechnic is a national leader in UAS 1xbet online games login , education and flight training. The UAS program is the principal initiative of the university’s Applied Aviation 1xbet online games login Center, which completes hundreds of missions yearly and allows students to participate in these missions, said Kurt Carraway, UAS program executive director.

Some UAS 1xbet online games login projects involve mapping natural resources and using UAS to inspect power infrastructure, such as power lines or wind turbines. The program operates under numerous FAA operational regulations, including Part 107 — the FAA’s newest regulations for small UAS commercial operations. The program began training students in those operations the day the regulations went into effect.

The harmony of clay

TheHarmonyOfClay


When graduate student Eliza Weber creates a ceramic bowl or vase, she also creates a ceramic chorus.

Weber, master’s student in fine arts,starts a new piece of pottery by wedging or slamming the clay against a table to remove all air bubbles. She rolls clay with a squeaky slab roller, throws clay on the potter’s wheel and uses the rhythmic wheel to form shapes. The clicking noises of the electric kiln or the burning noises of the gas kiln signify the artistic process is nearly complete.

Through ceramics, Weber is studying the continuity between form and pattern. Her pottery portfolio includes bowls, vases, plates, cups and 1xbet online games login vessels — often decorated in colorful geometric shapes, flowers and designs.

Exercising on Mars

ExercisingOnMars


Before astronauts explore Mars, NASAhas to make sure they are healthy and fit enough for outer space. 1xbet online games login kinesiology researchers have a solution.

Carl Ade, assistant professor of kinesiology, and his 1xbet online games login team have designed a Martian obstacle course — complete with red rubber mulch — that resembles the terrain of Mars. The NASA-funded course simulates critical mission tasks that astronauts may perform on the red planet — unloading cargo, walking for 1.5 kilometers and rescuing a crew member.

A key piece of equipment is a portable rowing system, which NASA plans to send to outer space with astronauts to measure their fitness level during long-duration missions. Using breath-by-breath metabolic and ventilatory data and ergometers such as the rowing system, 1xbet online games login can measure astronaut fitness to predict successful completion of the simulated critical mission tasks.

Listen to the rowing machine and 1.5 kilometer walk on the Martian obstacle course.

Fracturing and shattering

FracturingAndShattering


The road to stronger, safer concrete startswith the sound of it breaking.

Bob Peterman, professor of civil engineer- ing, manages the Structural Mechanics Laboratory where his 1xbet online games login teamtests the materials used to manufacture concrete railroad ties. Some machinescan apply up to 400,000 pounds of force to determine the compressive strength of concrete cylinders while others pull steel reinforcing wires in tension until they break.

These tests help Peterman determine at what point concrete and 1xbet online games login materials crack, shatter or break. His team uses that knowledge to improve concrete by making it safer and stronger.

Listen to the engineers conduct two tests: a compression test for a concrete cylinder and a tension test for a steel wire used in concrete railroad ties.

A 'glimmer' of sound

AGlimmerOfSound


For composer Craig Weston, sound begins with an idea: a pattern, an emotion ora tune. He often writes musical compositions in segments — one segment may focus on a faster tempo while another segment may feature only two instruments. Using notation software on the computer, Weston puts the segments together to create the finished work.

Weston, associate professor of music, has composed dozens of pieces and teaches student composition courses. He composes music for a variety of instruments in a variety of styles — 1xbet online games login orchestral to chamber to electronic music. His newest composition, “Glimmer,” is for clarinet, cello and piano and premiered in October at the College Music Society Conference in Santa Fe, New Mexico.

Listen to Weston explain the composition of “Glimmer” and listen to the computer program play a facsimile of the final piece.

Laser-induced thunder

LaserInducedThunder

Researchers at the 1xbet online games login ’s J.R. Macdonald Laboratory can use ultrafast lasers to create a thunderous sound. The laboratory, part of the physics department, hosts one of the country’s largest atomic, molecular and optical physics programs.

Physicists use the laboratory’s ultrafast lasers to expose ions, atoms, molecules, surfaces and nanostructures to short, intense bursts of electromagnetic radiation. 1xbet online games login — such as physics doctoral students Travis Severt and Brandin Davis — study these interactions to understand the properties of the systems and the dynamical processes that occur.

In one example, laser pulses are focused in air, which creates a plasma and induces a shockwave that creates sound, similar to lightning creating thunder. The frequency of the resulting sound is the repetition rate of the laser — 10,000 pulses a second 1xbet online games login lab’s PULSAR laser is a high squeal while the 1,000 pulses a second 1xbet online games login HITS laser is a muchlower hum.

Listen to the high pitch of the PULSAR laser.
