Zhanping You (CEGE/MTTI) has been appointed to the Michigan Department of Environment, Great Lakes, and Energy (EGLE) Scrap Tire Advisory Committee.

Section 16911(3) of Part 169, Scrap Tires, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended, states:

“The director of the department shall appoint a scrap tire advisory committee of individuals interested in the management of scrap tires to advise the department on the implementation of this part. In addition to such other issues as the department may request the committee to consider, the committee shall advise the department on the report required by subsection (2) and the relevance of a national standard or specification under section 16901(1)(f).”

Daniel Dowden (CEGE) was credited by DBusiness in a story about the benefits and potential of mass timber in the construction industry. Dowden provided info on mass timber buildings’ ability to withstand earthquakes.

Cited by National Geographic as the sustainable material with which future cities could be built, mass timber is an engineered wood that architects and builders increasingly see as a structural alternative to steel and concrete.

According to Dowden, steel and mass timber buildings can be built to respond in an equivalent manner to an earthquake of the same magnitude, but a mass timber structure built with cross-laminated timber walls that are designed to resist lateral forces must also be designed to withstand larger forces because wood is a brittle material compared to steel.

Organic molecules dissolved in rivers, lakes, seas and oceans are essential to plant and animal life. Some of these molecules are also degraded and enter a complex cycle of carbon, nitrogen and sulphur containing compounds. Surprisingly, scientists currently have a limited understanding of the fate of these molecules. Dr. Daisuke Minakata and his colleagues from Michigan Technological University are involved in an ambitious programme to overcome this critical knowledge gap.

Minakata was prompted to develop a theory to explain the loss of critical amino acids from water. He assumed that other organic molecules absorb the energy carried by the rays of sunshine and those reactive intermediates transform amino acids into small pieces. According to his theory, such light-activated compounds could act as catalysts, inducing the indirect breakdown of critical amino acids.

The Department of Biological Sciences recently acquired a new liquid scintillation counter through a collaboration with the Vice President for Research Office; College of Sciences and Arts; Department of Civil, Environmental, and Geospatial Engineering; Ecosystem Science Center; and Great Lakes Research Center.

This counter replaces an older, obsolete unit and is an essential piece of equipment for researchers working with or planning to work with radioisotopes. Researchers interested in using the new counter, or simply learning more about the about it, should contact David Dixon, director of biological laboratory operations, at dcdixon@mtu.edu.

Several of Michigan Tech’s ongoing rail transportation research projects were highlighted in Washington, DC, in early January, either as part of the Transportation Research Board (TRB) Annual Meeting, or as separate workshops and demonstrations.

Thomas Oommen (GMES) presented in a TRB workshop titled “International Perspectives on Strategies to Reduce Track-Caused Derailments,” and in a Track Support and Substructure Research Review organized by the Federal Railroad Administration.

Department of Cognitive and Learning Sciences PhD student Tauseef Ibne Mamun (applied cognitive science and human factors) presented our early work, titled “Multi-Site Simulation to Examine Driver Behavior Impact of Integrated Rail Crossing Violation Warning and In-Vehicle Auditory/Visual Alert System,” to the TRB AR080 Highway-Rail Grade Crossing Committee.

Richard Dobson (MTRI) gave an update on the Crossing-i drone technology development for improving grade crossing safety.

Pasi Lautala and John Velat (CEGE/MTTI), in collaboration with Battelle, hosted a booth in the TRB Exhibition and organized a daylong event outside the U.S. Department of Transportation headquarters to demonstrate the rail crossing violation warning (RCVW) technology.

Urban Milwaukee and Wisconsin Public Radio mentioned a Michigan Tech study in stories about advice from a panel of scientists that Great Lakes communities prepare for swings in high and low water levels in the face of climate change.

The study, led by Pengfei Xue (CEGE/GLRC), projected Lake Superior to rise 7.5 inches and the Lake Michigan-Huron system to rise 17 inches by 2050 due to climate change. From the study:

Climate modeler Pengfei Xue, of Michigan Technological University, and his team for the first time combined a high-resolution regional climate model and a 3D hydrodynamic model, along with hydrologic models to hone projections for lake-level rise.

“What we have built is a system that gives a better representation of the complexity of hydrodynamics and lake-atmosphere interaction and contributes to a more advanced modeling framework necessary for improving the Great Lakes’ hydroclimate projections. This is particularly evident through the markedly improved simulation of lake evaporation.”

Effective today (Oct. 10, 2022), Pengfei Xue (CEGE/GLRC) will become the Great Lakes Research Center’s first associate director.

Established in 2013, the Great Lakes Research Center (GLRC) has grown to include more than 100 affiliated faculty and research staff, achieving $9.2 million in new research awards and $7.1 million in research expenditures in fiscal year 2022. The GLRC’s portfolio includes core research in the areas of Great Lakes science and system processes, sustainability and marine technology adaptation.

Xue, an associate professor in the Department of Civil, Environmental, and Geospatial Engineering (CEGE), will lead the GLRC’s Hydrodynamics, Climate, and Environment Research Team, and contribute to the center’s long-term strategy development.

“I couldn’t be more pleased to support Dr. Xue’s appointment as associate director,” stated Tim Havens, director of the GLRC. “His leading hydrodynamic modeling research has been a shining example of the high-quality research going on at the GLRC, and his commitment to the strategic growth of the GLRC is evident in his mentoring of new scientists and engineers in his group. I’m thrilled to welcome him to the GLRC executive team.”

“I am proud of Pengfei’s success and the impact his research has had. He is an expert in the development of numerical models and computer simulations for the Great Lakes, as well as environmental risk analysis, seasonal forecasting and regional climate change, ” said Audra Morse, CEGE department chair. “More importantly, the appointment acknowledges the impact Pengfei has had on his colleagues and the work he will continue in an effort to support his colleagues’ growth as scholars.”
