Welcome Ask anyone who has ever been associated with the Department of Agricultural and Biosystems Engineering, and they’ll all say the same thing – our new building was a long time coming. For years, the department was housed in no less than four buildings, including Davidson Hall – a building with a rich history which included educating and employing the pioneers of our field. The Biorenewables Complex grew out of a need for modern research and teaching facilities to accommodate our growing department. These new facilities are critical for the future of our department. They allow us to recruit the best and brightest faculty, staff and students. They also allow us to educate students in modern facilities with modern tools and technology that helps us meet today’s needs from industry, institutions and organizations that employ our students. Additionally, we can better conduct critical research and extension projects important to the economic development of the State of Iowa and our great nation. We continue to employ high quality faculty and staff in the department. The following people joined the ABE ranks in 2013: •Norm Muzzy, retired from John Deere, is a lecturer for the engineering senior capstone courses. •Tamara Kerns is an academic adviser for Industrial Technology students. •Dana Woolley spends ½ time in ABE as our communications specialist. •Jennifer Grouwinkel is our account specialist. Also, our faculty have hired several staff members to support their ongoing research projects. As you read through our 2013 Annual Report, you will see the tremendous growth and impacts of our teaching, research and extension programs within ABE. We are very excited about the successes we have had in 2013 and what the future will bring for ABE in 2014 and beyond. Within these buildings, I see the future of our department, the future of our profession, and I can’t wait for the next chapter.

Undergraduate Highlights Letter from the Associate Chair for Teaching, D. Raj Raman: 2013 was a banner year for ABE teaching programs. The department broke through the 700 mark for total undergraduate students, an amazing milestone. Our teaching highlights over the past year include: adoption of blended learning models in an increasing number of courses; revision of a long-standing numerical methods course; development of a new continuous improvement process by the engineering curriculum committee that allows for better tracking and easier reporting for accreditation purposes; creation of a freshman engineering problem solving course specifically for ABE students; and the addition of a highly qualified engineer with decades of industrial experience to teach the engineering capstone courses. In blended learning models, faculty do more than just lecture. Many of our faculty have been doing more than just lecturing in our classes for years, but in blended learning models, they are more intentional about this, and typically leverage the use of technology. For example, in ABE 316 Numerical Methods, students viewed video lectures prior to class. When in the classroom, students worked on MATLAB VBA and Simulink programs with instructors serving in a mentor role rather than spending class time lecturing. Challenges with our experiences in 316 led us to take a slightly different blended approach in the spring 2014 offering of ABE 160, the freshman problem solving class for our engineering students. Instead of having students watch a video prior to coming to class, each student in ABE 160 watched the video during class with their own set of headphones. Students could watch the videos at whatever speed they wanted, work through the tasks and better understand the videos during class time with instructors present. Student performance, particularly in the programming portion of ABE 160, was far higher than in prior, 8

normal course offerings. We will take a similar approach in the numerical methods classes for 2015.

them indicating that they more clearly understood the relevance of mathematics in their practice engineerâ&#x20AC;&#x2122;s exam thanks to the class.

Other major revisions were made to the instruction of numerical methods of teaching class that the department had been offering for well over a decade. To more effectively give students exposure to modern engineering methods, the course shifted its focus to using MATLAB and Simulink for the simulation of dynamic systems. The course also incorporated a five-week section on the principles underlying, and the details on the usage of and interpretation of, data coming from the built-in solver capabilities in Microsoft Excel. This section also included additional VBA programming, which students see as freshman but which we in the department feel is important to reemphasize in a studentâ&#x20AC;&#x2122;s junior year. Student response to the new class was highly positive with many of

ABE has always been dedicated to the idea of hands on, problem oriented, student learning. At the senior level this includes a capstone experience for both our technology and engineering students. Last year, the department hired Mr. Norman Muzzy who had a distinguished career at John Deere as a design engineer. Muzzy has been leading the engineering capstone classes. Not only has he provided leadership in this area, but Muzzy has been a driving force behind new efforts to make available to students the fantastic fabrication facilities that we now have in Sukup Hall. Muzzy has created a proposal to develop what we are tentatively calling the ABE Maker Space, a place that will allow our creative students to make their visions into reality.

2013 ANNUAL REPORT

Graduate Highlights Grad student works to revolutionize grain storage, eliminate insecticides

Using six 55-gallon barrels, three will be open to the atmosphere with screens on top to avoid weevils escaping and allowing oxygen flow, and three will be sealed until the oxygen level drops below 4 percent, at which weevils cannot survive.

The amaranth for his project is provided by Mark and Marcy Jones, farmers from Oshkosh, Nebraska. When the research team initially contacted the Joneses to buy the grain, the couple decided to donate their own because they liked the research.

“With hermetic storage, we try to create an environment whereby the weevils will assume all the oxygen that is in the barrel,” explained Bbosa. “At the end of the day when they use up the oxygen, they have to die.”

Once Bbosa finishes the research here, he will visit another country in Africa to conduct the same research and confirm his results. He says he hopes it will be ready for use by farmers in the next three years.

Bbosa, a graduate assistant for research in agricultural and biosystems engineering, came from Uganda to get his master’s degree at Iowa State and began studying grain storage with his adviser, Tom Brumm, associate professor of agricultural and biosystems engineering.

Hermetic storage comes with more advantages than just killing off weevils: it also keeps rodents out of the storage structures, saves seeds for use during future growing seasons and eliminates the need for insecticides, which can be too costly for many farmers.

The project is funded by Sukup Manufacturing Company, and Bbosa said his research group is very thankful for the company’s support. “This project is expected to reduce the number of hungry people in developing countries.”

Bbosa, who earned his bachelor’s degree from Makerere University in Uganda, is working with Brumm to reduce grain storage losses caused by insects called maize weevils in Africa.

Bbosa said this method is a more cost-effective solution to grain storage. The airtight metal or plastic structures can last more than 20 years, compared to plastic bags that only last about two or three years.

The project developed when Carl Bern, professor of agricultural and biosystems engineering, saw the amount of grain loss in Tanzania and changed his research focus to hermetic grain storage, a form of airtight storage commonly used in developing nations.

While the focus is currently on helping subsistence farmers in Africa, Bbosa believes all farmers can start using this method and reduce use of insecticides worldwide. “It becomes environmentally friendly to the consumer because no chemicals have been used to preserve the grains,” he said.

Maize is a chief source of nutrition for about 900 million of the world’s poorest consumers and about one-third of all malnourished children, but poor grain storage can cut the amount of available maize in half. That’s why Denis Bbosa is at Iowa State studying new methods of safely storing grains.

“The idea is that if you deprive insects of oxygen in stored grain, they die, thus reducing or eliminating the loss of grain,” said Brumm. Current storage in Sub-Saharan African countries can result in up to 50 percent grain loss in some cases, which is often the difference between having extra grain to sell and going hungry, he added. Bbosa has been raising weevils to test hermetic storage, and the group is now ready to move the research to a larger scale.

12 WWW.ABE.IASTATE.EDU/REPORTS

Bbosa’s group is also looking at an alternative method to eliminate the weevils. They blend corn and amaranth—a small grain—to fill all the space within the stored corn. “By filling the interspaces between the corn kernels,” Bbosa said, “we assume that it eliminates the movement of maize weevils so they can’t get to a breeding spot or the kernels. Automatically they will die because they will not have access to food.”

Bret Euken BS, Agricultural Engineering - 2007 Process Water Recovery Supervisor for the Grain Processing Corporation in Muscatine, IA Why did you choose ISU? I knew I wanted to study engineering, and I knew that ISU had a great engineering school. Plus, I grew up on a farm and loved seeing and understanding how things worked. This naturally led me to study agricultural engineering. When did you first start working for Grain Processing Corporation (GPC)? I first found them at the engineering career fair in the fall of 2006. I started working for GPC

right out of college. I currently manage the process water recovery department. What is the process water recovery department responsible for? The process water recovery department is responsible for monitoring water quality going to the Mississippi river from the GPC Muscatine plant and operating the process water recovery water treatment facility. Where do you apply your engineering background in the workplace? As process water recovery supervisor, I use water balances daily in figuring out how best to divert flows to different equipment within the process water recovery water treatment facility. I also use engineering economics, physics, heat and mass transfer and unit conversions on a regular basis. Original interview by Eric Debner

ABE pioneers major growth for ISU’s Digital Repository

materials for anyone with an Internet connection, unlike a library catalogue or online database, which require login credentials or subscriptions.

The Department of Agricultural and Biosystems Engineering was the first to take advantage of Digital Repository @ Iowa State University when it was unveiled in April 2012, and ABE Chair Steve Mickelson has no regrets.

In the beginning, Mickelson wasn’t sure how faculty would respond to the idea, but he said they’ve been both “collaborative and pretty open-minded” as a whole.

The repository is “an online platform we can use to provide access to different types of materials,” according to Harrison W. Inefuku, the digital repository coordinator for Iowa State. Faculty, students and staff can place research, journal articles, graduate dissertations and other creative works online to provide open access to their work. “As department chair, I’m always looking for ways to expand our exposure across the world—as far as the research, teaching and other innovative extension work we’re doing,” he said. “I knew we’d be a good test case for this.” The online storage facility participates in a feature called the Digital Commons Network that aggregates all the content from every university that uses it. “You go to a specific discipline and you can look at a pie chart that shows you what percentage of those articles are coming from which university,” said Inefuku. When Iowa State started the repository, it held third place behind Nebraska and California Polytechnic State University. With the addition of Mickelson’s vitae alone, it surpassed Cal Poly. While Nebraska still boasted more than half the agricultural engineering works in the digital commons network, Inefuku pressed the department to build its presence. In less than three months, Iowa State’s ABE section surpassed that of Nebraska’s, climbing to about twothirds of the agricultural engineering works from universities across the commons—including Purdue, Tennessee, Kentucky and others. The repository provides open access to these

Even though journal articles are a large part of the material published on the repository, graduate theses and dissertations are also extremely prevalent. “It’s really great exposure for our grad students,” said Inefuku. “The theses and dissertations are very popular— they’re by far the most downloaded items we have in our repository,” he added. In the short time since the repository has been up, the most-downloaded theses have been downloaded more than 6,000 times and cited in peer review journals and by other universities. As the repository begins to grow and more colleges and departments begin to utilize it, Inefuku said he expects some difficulties in getting permissions even for manuscripts in other disciplines, especially humanities, where he said the culture of sharing is trickier. As for the time it takes for other departments to join the repository, Inefuku and Mickelson are unsure. “I think definitely every department will get on board,” said Mickelson. “Some will catch on quicker than others; some will be more pioneers like us and others will wait until almost everybody does it and then they’ll jump on board. “If more people are looking at Iowa State and citing our research, not only will our department’s rankings go up, but ISU’s ranking will as well,” he added.
