faculty/staff NEWS

David Bowen, assistant professor, Department of Art and Design, opened his installation Tele-Present Wind on June 3 in Duluth and Moscow. Bowen's installation consists of a series of 21 x/y tilting devices connected to thin dried tansy plant stalks installed in the gallery in Moscow, Russia and a dried tansy plant stalk connected to an accelerometer installed outdoors. When the wind blows it causes the stalk outside to sway. The accelerometer detects this movement transmitting it in real-time to the grouping of devices in the gallery in Moscow.

The data collected by the sensor is sent in real-time via the internet to the installation in Moscow. Thus the individual components of this installation in Moscow move in unison as they mimic the direction and intensity of the wind in Minnesota. View the accelerometer via webcam at http://www.d.umn.edu/vdil/news/Wind-Cam.html.

Alexandra Luong, associate professor, Department of Psychology, received a Faculty Interactive Research Program (FIRP) award from the UM Center of Urban and Regional Affairs (CURA).

Eun-Kyung Suh, associate professor, Department of Art and Design, will exhibit her work Whispering Wishes at the show "North of the 45th 2010" in the Devos Art Museum at Northern Michigan University in Marquette, MI, June 4 - July 25. Eun-Kyung Suh's work Between is part of Minnesota Center for Book Art’s exhibition “Prints: Now in 3D.” The exhibition runs July 9 - Oct. 31.

NRRI NEWS

Subhash Basak was an author on two of the top cited articles by the Journal of Chemical Information and Computer Sciences:
1) “On 3-D Graphical Representation of DNA Primary Sequences and their Numerical Characterization” authored by M. Randic (National Institute of Chemistry, Slovania), M. Vracko (Iowa State University), A. Nandy, and Basak (both of UMD-NRRI).

Mike Cable and Sam Firoozi won first place in the Advanced Finishing category at the 3D Systems User Group annual conference in April with their model of a 1776 English dueling pistol. The model was made in the rapid prototyping center at UMD’s Natural Resources Research Institute on the selective laser sintering machine. The 3D Systems User Group is a professional network of manufacturing engineers, industrial designers, product development specialists and rapid prototyping technicians. The annual conference provides a forum for the presentation of new technologies related to 3D Systems equipment.

MN SEA GRANT NEWS

Jeff Gunderson facilitated a session at the Ecology of Lake Superior Conference held in May at the EPA Mid-continent Ecology Division Lab in Duluth. He also participated in the National Sea Grant review of Knauss Fellows in Silver Spring, Maryland in May. Gunderson also presented the session, "The risk of spreading AIS through the sale and distribution of live bait," at the Lake Superior Invasive Species Prevention Workshop held June 1 at the EPA Mid-continent Ecology Division Lab in Duluth.

Douglas Jensen, aquatic invasive species program coordinator, spoke at the Combating Aquatic Invaders Conference in the Flathead Watershed in Polson, Montana, in May, where he gave three presentations. He also co-hosted the Lake Superior Invasive Species Prevention Workshop held June 1 in Duluth, presenting two sessions. The workshop informed federal, state, provincial, and tribal agencies of the Lake Superior Aquatic Invasive Species Complete Prevention Plan and promoted the plan's recommendations. Jensen was interviewed by Boua Xiong, KBJR-TV, and the segment aired on the 6 p.m. news that day. Jensen was also elected chair of the Great Lakes Panel on Aquatic Nuisance Species' Information and Education Committee at the panel's spring meeting in Maumee, Ohio, in April, and participated in an Invasive Species Education Planning Committee Meeting, in April, in Andover, Minnesota. Jensen also earned a master's degree in education from the University of Minnesota Duluth this spring.

Sharon Moen, science writer, won a Gold Award, the top prize for writing, at the University of Minnesota's annual Communicators Forum awards ceremony in May in the Twin Cities. Moen's article, "Voracious Vegetation," with collaboration by Doug Jensen, was published in Cabin Life magazine in June 2009.

Jesse Schomberg presented a rip currents session at the Northland Water Safety Workshop, co-sponsored by Minnesota Sea Grant. Schomberg also helped facilitate the annual truckload sale of Systern rain barrels and Earth Machine composters in May at Lake Superior College.
