Badylak - SIS2-- Dr. Stephen F. Badylak holds newly developed material made from pigs' intestines that is being used in a clinical trial to replace damaged ligaments. The material can be configured into sheets as thin as two or three cells.
Badylak - DePuy-- Rhonda Clarke, senior biomaterials research scientist, prepares processed SIS for packaging in DePuy's pilot manufacturing facility in Warsaw, Ind. The material will be used to replace ruptured anterior cruciate ligaments of the knee.
Goodman - Ceiling-- Research on women in management positions suggests that women are cracking, but still rarely breaking through, the corporate "glass ceiling." The study, co-authored by Jodi S. Goodman, assistant professor of organizational behavior at Purdue University's Krannert Graduate School of Management, notes that althought the percentage of women in management positions has grown for 18.5 percent in 1970 to more than 40 percent today, only 3 percent to 5 percent of top managers are women.
Frederickson - Dissection-- This illustration shows how five 10-sided figures can be cut to make one large decagon. The 17-piece dissection first appeared in 1974.
Minchella - Housecalls-- Associate Professor Dennis Minchella tutors students at Purdue's Shealy Residence Hall. Pictured clockwise from Minchella are freshman Jackie Webster, a pre-veterinary science major from Crown Point, Ind., and freshman Lisa Graves, a neurobiology major from Southport, Ind.
Chapple - Lignin-- Purdue biochemist Clint Chapple raises Arabidopsis plants in a growth chamber. His research with the plants could help the wood industry produce paper with less waste and fewer harmful chemicals.
Snyder - Otter-- Paul W. Snyder, left, is a Purdue veterinary pathologist studying the effects that the Exxon Valdez oil spill has had on Alaskan sea otters. He and a member of the National Geologic Survey carefully take a blood sample from an anesthetized otter.
Harbor - Lots-- Which lot would you choose? A Purdue University study finds that homebuyers perceive a seeded lot to be worth $750 more than a comparable bare lot. These lots, in Walden Oaks subdivision in Geauga County, Ohio, are identical in size, though the grassy lot may produce a larger profit for the developer.
May - Literature-- Natalie Kinsey-Warnock, a children's author from Vermont, reads one of her yet-to-be published books to fifth-grade students at Klondike Elementary School in West Lafayette, Ind. It's part of a Purdue program based on the belief that classroom visits are an important tool for building enthusiasm about reading for fun and leisure.
Blume - New 4H-- 4-H'er Shannon Grimes of Columbus, Ind., gives a guiding hand to A.J. Sherman (middle) and Alison Turner during Pre-Schooler Day at the Bartholomew County Fair.
Sparks - Survey-- For persons uncertain about their beliefs in flying saucers, witches and other paranormal phenomenon, seeing such oddities on television may influence their decisions about the existence of such things, based on a survey by a Purdue communication professor.
Hengst - Dinosaur-- This life-size model of Pianitskisaurus, a Jurassic carnivore of modest breathing capabilities, is at the Museum of Paleontology, Patagonia, Argentina. This medium-sized dinosaur, dating back 137 million to 190 million years, had not evolved the more advanced breathing systems of its North American cousins. By the middle Cretaceous period, about 100 million years ago, the Argentine carnivores became the aerobic equals of North American dinosaurs.
Chaturvedi -Wargame-- Purdue management students check their market position in a computer-simulated market economy. Purdue's Shailendra Mehta (standing left) and Alok Chaturvedi (standing right) are the developers of the program.
Chaturvedi -Wargame-- Participants follow the outcomes of a simulated market economy game, through 3-D graphic projections, which Chandrajit Bajaj, Purdue professor of computer science, helped develop.
Finke - Nuns-- Reforms meant to make life in Catholic religious orders more appealing may do just the opposite. Purdue sociologist Roger Finke says a 1993 survey of women's religious orders found that the new-member rate for orders that had lessened requirements after Vatican II was 41 per 1,000 members in final vows. That compares to a rate of 95 per 1,000 members for orders that hadn't changed.
Haring - Charter-- Charter school status for each of the 50 states as of August, according to the Center for Education Reform.
Brentari - ASL-- American Sign Language classes are filled to capacity at Purdue. This popular class provides a different perspective on learning a foreign language because it's visual and gestural, as instructor Donald Haring demonstrates.
Diamond - Preschool-- Children at a Purdue University preschool left, and Purdue entomology Professor Jeff Stuart stand in a field of corn damaged by the western corn rootworm. The weakened roots - shown on the plant held by Stuart - can cause the plants to fall over during summer storms. Researchers at Purdue have determined for the first time that a new genetic variant of the No. 1 pest of corn actually prefers soybeans over corn for laying its eggs. That is bad news for farmers in the Eastern Corn Belt, who use corn-soybean crop rotation to control the pest.

That is bad news for farmers in the Eastern Corn Belt, who use corn-soybean crop rotation to control the pest.
Gore - Flame-- Gore - Lab-- Jay Gore, Purdue professor of mechanical engineering (foreground), and his doctoral student Xian-Chua Zhou use a sophisticated laser technique called particle imaging velocimetry to investigate how air flows into a fire. These data are being used to better estimate how much carbon monoxide and other toxic products are emitted from a fire, information that could affect building ventilation codes and help firefighters better estimate how much of the poisonous gases are present in areas such as corridors. To measure the velocity of the air flow into the flame, the researchers artificially seed a special flame chamber with particles. When a flame is lit, the particles travel with the air into the flame. A laser, pulsing once every 150 microseconds, shines on the flame and reflects off the particles and into a camera, which records an image of the particles with each pulse. By carefully measuring the tiny distance a particle moves between laser pulses, the researchers can determine the velocity of the particle, and hence the speed of the air flow.
Gore - Detector-- Yudaya Sivathanu, a Purdue research scientist (right), and graduate student Andrew Lloyd are part of a team that has developed a new type of fire detector that may one day be hooked up to a home personal computer or telephone to automatically notify the fire department when a fire is detected. The device uses fiber optics to detect the characteristic infrared radiation signature of an uncontrolled flame.
Weaver - Adolescents-- Connie Weaver, Purdue professor of foods and nutrition, and lab assistant Leslie Borman use a bone densitometer to measure an adolescent girl's bone strength. Weaver's research has found that adolescent girls don't get enough calcium during their "window of opportunity" of bone growth during puberty, which may result in osteoporosis later in life.
Reicher - Spikes-- Many golfers are replacing the metal cleats in their golf shoes with nonmetal or alternative cleats, like the ones shown here. More than 1,500 U.S. golf courses have banned metal spikes because they tear up the turf on golf courses, says Purdue turf expert Zac Reicher.
Smith - Foodsci-- Purdue food scientist Steve Smith (right) mixes tomato paste into water for testing on the McNabb Turbidity Sensor and the Maselli Refractometer, as Kent Wert, manager of Purdue's computer-integrated food processing lab, monitors the computer and food science junior Ben Siurek of Greenfield, Ind., controls the flow rate.

The dog had swallowed a fish hook that became stuck in its throat.
Mongeau - Graphic-- Purdue engineers are developing a thermoacoustic refrigeration device that uses sound waves to cool. A vibrating acoustic driver (left) causes gas atoms inside the device to oscillate, setting up pressure fluctuations, or sound waves, which in turn cause temperature fluctuations. The result - the one end of the device (right) becomes cooler than the other.
Mongeau - Refrig-- Brian Minner, left, a doctoral student, and Luc Mongeau, assistant professor of mechanical engineering at Purdue, perform an impact test on the acoustic (loudspeaker) driver, a component of their prototype thermoacoustic cooling system, which should be complete and ready to test in early July.
Tishmack - Soil-- Purdue researchers have developed a process to make a nutrient-rich soil additive from coal ash, industrial byproducts and yard waste. Here, oxygen levels inside the composting material are closely monitored by Patrick Tishmack, left, a graduate student in chemistry at Purdue, and Alexander Bunn, assistant site manager with ReUse Technology, a North Carolina company.
Haring - Hopes-- Francie Powers of Monticello, a sophomore in elementary education at Purdue, learns new teaching methods in the High Hopes project while helping Andre Turner, a first-grader at P.S. 65 in Indianapolis, finish a homework assignment.
Sullivan - Credit-- Charlene Sullivan, associate professor of management at Purdue, is a fan of "affinity" credit cards sponsored by a store or organization. She says they often are good deals for consumers, the banks that issue them and the organizations that sponsor them.
Morrison - Adventure-- Aging baby boomers are participating in one of the fastest-growing areas of the travel industry: adventure vacations. Here Purdue News Service photographer David Umberger scales Der Zerkle, in the Flatirons near Boulder, Colo. Travel expert Alastair Morrison says adventure vacations need not be strenuous, they just need to be active.
Schmieder - Grading-- Purdue University chef Hubert Schmieder and Tippecanoe County ostrich farmer Jim Jones look on as some playful ostriches play keep-away with the chef's hat. Schmieder has been working to standardize the worldwide grading system for ostrich meat.

The study aims to provide data that will allow manufacturers to boost the power of their systems without causing uncomfortable sensations in patients.
Schweitzer - CD-- Purdue University's "Corn Growth, Development and Diagnostics - Germination to Knee High" CD-ROM packs bushels of corn and crop problem information and pictures onto one disk. Useful for corn farmers and crop consultants, the multimedia program also has proven its worth in the classroom.
Rube - National-- This cartoon, showing a machine that helps a numskull become an engineer, was drawn for Purdue students by Rube Goldberg in the early '50s. According to Goldberg: Seal balances ball and applauds self, causing string to start one-man band. Co-ed, hearing music, does Charleston, kicking over oil lamp and burning string, dropping basketball on switch, which starts atomic machine, lifting numskull so he can crib answers and become a successful engineer.
Nelson - Citizenship-- All these report cards from the 1960s and '70s included grades for citizenship. The highlighted section is from a 1963 report card.
Ejeta - Seeds -- Purdue Professors Larry Butler (left) and Gebisa Ejeta not only developed pest-resistant sorghum for African farmers, they also grew eight tons of seed and arranged for it to be distributed in Africa. Butler, who died in February, told colleagues that the effort was the happiest and most satisfying of his career.

Rowe - Homebiz-- Jean E. Ness of rural Lafayette takes time out to help her granddaughter, Micah, with a project of her own. Ness, who runs Ness Financial Services Inc. out of her home, says being attentive to grandchildren and other family members is just one of the many distractions she faces working at home.
Rube - State-- At the Rube Goldberg Machine Contest, the machines don't always work as planned, as these Purdue students learned the hard way during the 1996 contest. The challenge for the 1997 contest is to build a machine that uses at least 20 steps to load a CD into a computer and run a program, or into a CD player and play music.
Koltick - Electron-- According to recent measurements made by Purdue physicists, an electron may not be a simple point charge, as previously thought. Instead, the particle may be thought of as being at the center of a fuzzy "cloud," as in this artist's conception, where the electromagnetic force increases toward a central core. The "cloud" consists of virtual particles, which wink in and out of existence in pairs - one particle positively charged (light gray), the other negatively charged (dark gray).
Peppas - Adhesive-- Purdue biomedical engineer Nicholas Peppas has developed a new type of material that adheres to the skin and can be used to deliver drugs to wounds in a slow, controlled manner, speeding up the healing process.
Sahley - Leech-- The medicinal leech, once used in medicine to draw blood from patients, may provide new clues to neural regeneration. Purdue researcher Christie Sahley and her research assistant, Orie Shafer (background), are using the leeches to analyze the role nitric oxide synthase plays in a regenerating nervous system.
