Enrollment Up Again

by Jennifer Donovan, director of public relations

Enrollment rose again this school year, topping last year’s number by 118 students. Fall enrollment figures tallied last night totaled 7,132.

A surge in Graduate School enrollment accounted for the increase, including increasing enrollment of international graduate students. The Graduate School reported 1,189 students, the most ever and a 21-percent increase over fall 2008. The number of international graduate students is up more than 17 percent.

“This is the highest headcount since 1983,” said President Glenn Mroz. “It shows that, increasingly, students see a Michigan Tech education as a high-return investment providing them with skills in great demand in our competitive world. Our strategic plan calls for increasing our graduate offerings while maintaining the size of undergraduate enrollment in high-demand science, technology, engineering and mathematics (STEM) fields. That is a critical way to provide the advanced training that will support the expansion of the entrepreneurial knowledge economy in Michigan.

“But to accomplish those goals,” Mroz continued, “something must be done about the issue of state funding. We are educating 40 percent more students than we did 40 years ago with the same level of state support.”

Jacqueline Huntoon, dean of the Graduate School, said she is extremely pleased to see such a large increase in graduate enrollment this year. “This shows that everyone at Michigan Tech is committed to increasing the size and quality of our graduate programs, in accordance with the University’s strategic plan,” she said. “It is because of our outstanding faculty, staff and current students that we are able to attract so many students from around the world.”

The record graduate student numbers include approximately 100 nondegree-seeking automotive engineers enrolled in a special advanced propulsion technology course offered in Detroit by Michigan Tech and the Engineering Society of Detroit.

Among undergraduates, the average ACT score of entering first-year students rose to 26.0 this year. The ACT score is one of Tech’s key indicators in achieving its strategic goal of attracting outstanding students, faculty and staff.

“We are attracting an academically more talented freshman class,” said John Lehman, assistant vice president for enrollment. “That indicates that our scholarship and financial aid programs are doing what they are supposed to do, enabling those who have need and are strong academically to attend Michigan Tech.”

The percentage of new female students at Tech also rose, from 23 percent last year to 26 percent this year. The University also saw a 9.8-percent increase in undergraduate transfer students, reflecting Michigan Tech’s enhanced efforts to reach out to community college students.

Undergraduate enrollment fell by 90 students this fall, to 5,943, although the number of transfer students rose by almost 10 percent. “The decrease is relatively minor and mostly related to the economy,” Lehman said. “Our undergraduate enrollment still stands well above totals from 2004 to 2007.”

Young researcher and his mentor team up on lake inquiry

Published in Tech Today

by John Gagnon, promotional writer

Scientists at Tech are known for their expertise in lake restoration and management, much of it applied to pristine Lake Superior. Now two researchers, an old hand and a budding scholar, are working on a small UP lake that is nearly choked to death.

Iron Mountain’s Crystal Lake, once a place for swimming and fishing on the southwest side of the city, doesn’t live up to its name anymore. A beautiful little lake has become a blight.

“People didn’t know where to begin to address the situation,” says graduate researcher Jarron Hewitt, a master’s student in environmental engineering. As part of a Senior Design project when he was an undergraduate, he and his fellow students helped out.

This 50-acre lake is fed by groundwater and has no natural inlets or outlets; but it receives storm-water discharges, which have proved to be its nemesis.

Storm water often has high levels of coliform bacteria from fecal pollution originating from animal waste (dogs and geese) and, potentially, humans. Following storm-water discharges, coliform levels in the lake exceed public-health standards for swimming.

Storm water also carries phosphorous-rich lawn fertilizer that stimulates algae growth. In the winter, when the lake freezes over, algae die off, sink to the bottom, decompose and turn into muck. “The history of the lake is in the muck,” Hewitt says, and there’s a lot of it–11 feet and counting. Historically, the lake was 20 feet deep; now it is 9 feet deep. The difference is muck. Core samples show that almost all of it is dead algae and other plant material, which, in the process of decomposing, use up oxygen. Telltale, then: lots of dead fish–mostly perch, bullheads, and minnows–in the spring. “The lake can’t provide a healthy environment for fish in its current state,” Hewitt says.

The charge for him and his fellow Senior Design students was: assess the condition of the lake and propose ways to restore it to beauty and “beneficial uses”–like recreation. The students started their inquiry in January and came up with three recommendations:

* Divert storm water, the source of the coliforms and fertilizer, from the lake.

* Aerate the lake to make sure there’s more oxygen for fish.

* Dredge the lake to get rid of the muck that recyles phosphorous and consumes oxygen.

Hewitt, who works under the guidance of Professor Marty Auer, is now refining the project on his own and coming up with an engineering plan to restore the lake. The work will be the basis for what Auer calls “a shovel-ready” restoration plan. “You can’t look for money unless you have a plan,” Auer says. So Hewitt is addressing more design detail and estimating the cost of the three fixes.

Hewitt is getting a taste not only of research and engineering, but also the shaping of public policy. He outlines the issue for public discourse this way: how good do you want your lake to be? “What we would like them to do is a complete restoration of the lake,” Hewitt says.

However, he confronts a reality of all enterprise: money to do the job. The biggest job, dredging, would cost several million dollars. It’s not an all-or-nothing situation. One possibility is to dredge part of the lake to improve the beach area. Also, diverting storm water would start the fix.

Auer’s time in this effort is pro bono; Hewitt needs to find money. “He’s bootstrapping this,” Auer says. “He’s supporting himself by delivering pizzas.”

Tech got involved with this issue when a Tech alumnus, who is a consulting engineering working with the City of Iron Mountain, asked Auer for help. “They’re a neighbor,” Auer says. “They’re part of our regional community. So it’s appropriate that we help them.”

He likes the job of mentoring students like Hewitt. “It’s huge for me. It’s what keeps me in it. Bringing experience to bear in partnership with students is really exciting and rewarding. It’s a great part of my job.”

He deflects attention, though, and says Hewitt “is the face of this project” who has “carried a lot of the responsibility,” including working with the city council and other civic leaders.

For his part, Hewitt is excited to help the people of Iron Mountain perhaps improve their community. Back in his hometown of Gwinn, before he ever came to Tech, he never imagined such a “hands-on, real-world opportunity.”

“I feel like I’m giving something back,” he says.

In late August, Hewitt and Auer visited Fergus Falls, Minnesota, to assess another lake severely polluted by storm water.

Auer is energized by these opportunities—what he calls “the excitement of being in a chase and pursuing mysteries.” He likens them to Sherlock Holmes, who, on learning of a new mystery, said, “Come quickly, Watson, the game is afoot.”

These days, then, Auer is inclined to say, “Come quickly, Hewitt….”

Better Safe than Sorry: Swine Flu Preparation at Michigan Tech

Published
By

Tech Today

Over a million Americans contracted swine flu between April and June 2009, most with no serious consequences, according to the federal Centers for Disease Control. But because the illness, caused by the H1N1 virus, is contagious and children and young adults have a higher hospitalization rate than adults (2.1 per 100,000 people for ages 5 to 24), schools and universities across the country are taking precautions in the event of an outbreak.

Here are some of the steps that are being taken at Michigan Tech:

* Hand sanitizer dispensers are being installed at the entrances to computer labs and other high-traffic locations. Everyone is encouraged to wash their hands regularly and have their own sanitizer for regular use.

* A hand washing and hygiene education plan is in place in the residence halls and will be expanded to include the rest of the campus.

* An H1N1 webpage is available with advice to prevent catching the flu, and what to do if you have the flu.

* A swine flu vaccination clinic is planned for fall semester, depending on the availability of the vaccine. It should occur in mid-October.

* As with any contagious illness, students and employees with flu-like symptoms are encouraged to isolate themselves as much as possible, either by staying home or in their residence hall room, until they feel better.

* Supervisors and faculty are being encouraged to be flexible in administering their absenteeism/excuse policy in the event of an outbreak.

The University communicates regularly with the Western Upper Peninsula Health Department and receives weekly updates on swine flu in the area. In addition, the University has a pandemic plan that will be activated in the event of an outbreak of H1N1 or other communicable diseases.

International Graduate Student Applications Continue to Rise at Michigan Tech

Published

Michigan Tech News

By Jennifer Donovan

August 26, 2009—

Unlike graduate schools nationwide, Michigan Technological University attracted more international graduate students this year than last. Numbers of applicants and accepted graduate students from India and South Korea—which dropped dramatically at graduate schools nationwide—also rose at Michigan Tech.

Last week, the Council of Graduate Schools issued a report showing that nationwide, admissions of international students to graduate schools dropped 3 percent, while admissions of students from India and South Korea dropped 16 percent   Applications for graduate school from international students rose only 4 percent nationwide, a lower rate of growth than in 2008.  Applications from India dropped 12 percent and from South Korea, 9 percent.

At Michigan Tech, applications from international graduate students rose 13 percent and admissions jumped 23 percent. Applications and admissions of graduate students from India and South Korea also rose at Tech.

“This is in part due to the fact that we offer STEM (science technology, engineering and mathematics) plus business, which draw students,” said Graduate School Dean Jacqueline Huntoon.  “It is also because Michigan Tech’s Graduate School staff work hard to recruit students, and the departments are helping out by responding to applications quickly. It’s really a team effort.”

Graduate school applications from US citizens and permanent residents also increased 28 percent from 2008 to 2009 at Michigan Tech. Nationally they also increased, but only by 6 percent. Admissions of US citizens and permanent residents increased 4 percent nationwide this year and 32 percent at Michigan Tech.

“Growing our Graduate School, both in numbers and in quality, is one of the goals in our Strategic Plan,” said President Glenn D. Mroz. “It’s an important way to increase our stature as a technological research university. This is also part of an effort to bring some of the best minds in the world to Michigan. That is critical for Michigan to be a player in the creative economy.”

The Council of Graduate Schools’ report was based on survey data submitted by 253 graduate schools, including Michigan Tech.

Michigan Technological University is a leading public research university, conducting research, developing new technologies and preparing students to create the future for a prosperous and sustainable world. Michigan Tech offers more than 130 undergraduate and graduate degree programs in engineering, forestry and environmental sciences, computing, technology, business and economics, natural and physical sciences, arts, humanities and social sciences.

Pandey Group Models Molecular Transistor

Published

Published in Tech Today

by Marcia Goodrich, senior writer

Electronic gadgetry gets tinier and more powerful all the time, but at some point, the transistors and myriad other component parts will get so little they won’t work. That’s because when things get really small, the regular rules of Newtonian physics quit and the weird rules of quantum mechanics kick in. When that happens, as physics professor and chair Ravindra Pandey puts it, “everything goes haywire.”

Theorists in the field of molecular electronics hope to get around the problem by designing components out of a single molecule. Pandey’s group has done just that–theoretically–by modeling a single-molecule field-effect transistor on a computer.

“Transistor” has been an oft-used but rarely understood household word since cheap Japanese radios flooded the US market back in the 1960s. Field-effect transistors form the basis of all integrated circuits, which in turn are the foundation of all modern electronics.

A simple switch either diverts current or shuts it off. Transistors can also amplify the current by applying voltage to it (that’s how amplifiers work).

A diagram of Pandey’s three-terminal single-molecule transistor looks like an elaborate necklace and pendant, made up of six-sided rings of carbon atoms bedecked with hydrogen and nitrogen atoms. His group demonstrated that the electrical current running from the source to the drain (through the necklace) rises dramatically when voltage applied at the gate (through the pendant) reaches a certain level.

This happens when electrons in the current suddenly move from one orbital path around their atoms to another. Or, as Pandey says, “Molecular orbital energies appear to contribute to the enhancement of the source-drain current.”

Their virtual molecule may soon exist outside a computer. “Several experimental groups are working to make real our theoretical results,” says Pandey.

An article on the molecular transistor, “Electronic Conduction in a Model Three-Terminal Molecular Transistor,” was published in 2008 in the journal Nanotechnology, volume 19. Coauthors are physics graduate student Haiying He and Sashi Karna of the Army Research Lab.
