Social Structure of Bats Helps Them Survive
Study of Quake Damage Aided by New Machine
By GARY PETERSON Kansan Staff Writer
The study and prevention of severe earthquake damage to buildings and bridges will be possible with the aid of a new machine purchased by the Kansas School of Engineering.
The machine, called an electrohydraulic closed-loop testing machine. The name MATERIN'S Testing System) will be used by graduate students in the Engineering and Architecture Schools as a

Pressure may take the form of stretching, compressing, or vibrating.
A house has been constructed in which learned Hat. To its waste are wills and the pressure unit, Vibrations are created to find the point at which the air is compressed.
In later experiments, human subjects will be stationed in the house and three psychologists will observe the vibration affects them on.
"No one wants to walk down the hall of a building and feel the wall of concrete walking" Kenneth H. Lenzen, professors of civil engineering.
Stanley Rolfe, professor of civil engineering, said that the MTS
would be used to teach engineering and architecture students to design lighter, less expensive buildings with less floors. You'll also compensate for the previously unmeasured stress factors.
Rolf said that most buildings and bridges have been designed to be twice as strong as they need to be.
Machine to Help Deaf, Changes Sound to Sight
By KAY CHRISTENSEN
The psychology department also plans to use the MTS to simulate earthquakes and study their affects on people.
COLUMBUS, Ohio (UPI)—Learning how to speak properly can be a trying experience for the deaf, but the development of a language which changes sound to sight may bring to a valuable teaching aid.
The Voecore changes sound into distinct patterns of vibration which is then patterned on a screen lit up by light bulbs.
The machine, called the Voeder, was developed recently at Ohio State University under the supervision of Dr. R. Weed, an electrical engineer.
Heilen Reynolds, an oral instructor at the Ohio School for the Deaf, used the Vocoder with two students for a brief period of time.
"My experience with it was with two children," over a period of three weeks—four one-hour lessons a week. she explained
The University of Kansas is behind most other engineering schools in getting an MTS, a truck said. The MTS costs $40,000.
A deaf person has difficulty learning how to speak because he cannot hear the correct pronunciation of words or a gesture with his mouth the Vocoder, however, a person could attempt to voice the correct sound by matching the visual pattern on the screen. When it is not the student, he knows he has obtained the right pronunciation.
Miss Reynolds said with such limited use it was difficult to tell if the Vocoder would become a revolutionary advance for the deaf people, but "they were encouraged and they were motivated."
"It can be a very useful and helpful device. It does have the potential to analyze the letter patterns carefully project the speech patterns."
We said he hoped the machine would be further developed as a teaching machine to help us understand what is required to help. More work is needed, he said, to give some "leeuw" so when a student turns his head while speaking, it will not affect the speech pattern.

Bats that live together stay fat together, Thomas H. Kunz, independence, Mo., graduate student, has discovered
Kunz said the bats he was studying were found from Mexico to the Central Plains, but his research only included an area known as the Gypsum Hills. For one of the three years he studied volcanoes, a series of bat, commonly known as cave or Mexican brown bat.

Group Living Beneficial
Kunz used a special method to catch the bats. He trapped them by suspending several strands of tape on their backs. The bats, unable to perceive the obstacle, flew into the trap and fell into plastic bags. By trapping them in plastic bags, he weighed and banded them, and then repeating this procedure when the bats returned from the rain to calculate the bats' daily consumption.
Kunz also studied their social structure. He found that during the winter "bats that tend to cluster in groups lose sight of their environment," *isolated*.
He said this was because groups were less exposed to fluctuating temperatures which could affect individual body temperature.
Bats are heterothermic mammals in winter. Kunz said. This means their body temperatures change.
regulating their body temperature and lose more weight than bats that cluster.
The bats spend their winters in caves for protection from the constantly changing temperature outside of the cave.
In caves the bats reduce their body temperature and slow their metabolite rate, which enables them to survive. November to March, Kunz said.

--bats hang in a type of suspended physical state, in which their functions and the process of breathing are involved. Their heart rate is around 200 beats a minute when resting and 600 beats a minute when flying. These muscles are ceiling in winter it slows to two or three beats a minute. Their body temperature drops from around 15°C to about 48 degrees Fahrenheit.

Kunz said he became interested in bats as an undergraduate at Central Missouri State, where he obtained his bachelor's degree in biology. Since then he has obtained his degree from Drake and will receive his doctorate here this spring.
Kunz obtained a three year research fellowship from the Kansas Biological Survey to make his study on cave bats.
