Digital Bridges to Dance
-
Description
-
Digital Bridges to Dance is a collaborative project by Grinnell College professor Celeste Miller, MFA, and Grinnell College students Obuchi Adikema (Class of 2021, Vivero Fellow); Charlotte Richardson-Deppe (Class of 2019); and Naomi Worob (Class of 2019). The objects in this collection include methods for choreographers to collaborate across geographic distance for the purpose of professional artistic development; curriculum for dance-based experiential embodied practices that can be used by choreographers and other artists, classroom teachers, and community leaders; and documentation of the research and creative products of Miller, Adikema, Richardson-Deppe, and Worob.

Characterizing the soil microbiome and quantifying antibiotic resistance gene dynamics in agricultural soil following swine CAFO manure application
-
Description
-
As agriculture industrializes, concentrated animal feeding operations (CAFOs) are becoming more common. Feces from CAFOs is often used as fertilizer on fields. However, little is known about the effects manure has on the soil microbiome, which is an important aspect of soil health and fertility. In addition, due to the subtherapeutic levels of antibiotics necessary to keep the animals healthy, CAFO manure has elevated levels of antibiotic resistant bacteria. Using 16s rRNA high-throughput sequencing and qPCR, this study sought to determine the impact of swine CAFO manure application on both the soil microbiome and abundance of select antibiotic resistance genes (ARGs) and mobile element genes (erm(B), erm(C), sul1, str(B), intI1, IncW repA) in agricultural soil over the fall and spring seasons. We found the manure community to be distinct from the soil community, with a majority of bacteria belonging to Bacteroidetes and Firmicutes. The soil samples had more diverse communities dominated by Acidobacteria, Actinobacteria, Proteobacteria, Verrucomicrobia, and unclassified bacteria. We observed significant differences in the soil microbiome between all time points, except between the spring samples. However, by tracking manure associated taxa, we found the addition of the manure microbiome to be a minor driver of the shift. Of the measured genes, manure application only significantly increased the abundance of erm(B) and erm(C) which remained elevated in the spring. These results suggest bacteria in the manure do not survive well in soil and that ARG dynamics in soil following manure application vary by resistance gene.

Chicago, Burlington and Quincy Depot, Elliott, Iowa
-
Description
-
Looking northwest from Main Street at the Elliott Depot in Elliott, Iowa, with several railroad employees standing out front. The Chicago, Burlington and Quincy Railroad (reporting mark CBQ) was a railroad that operated in the Midwestern United States. Commonly referred to as the Burlington Route, the Burlington, or as the Q,[1][2] it operated extensive trackage in the states of Colorado, Illinois, Iowa, Kansas, Kentucky, Missouri, Montana, Nebraska, Wisconsin, Wyoming, and also in New Mexico and Texas through subsidiaries Colorado and Southern Railway, Fort Worth and Denver Railway, and Burlington-Rock Island Railroad.[citation needed] Its primary connections included Chicago, Minneapolis–Saint Paul, St. Louis, Kansas City, and Denver. Because of this extensive trackage in the midwest and mountain states, the railroad used the advertising slogans "Everywhere West", "Way of the Zephyrs", and "The Way West".

Chicago, Rock Island and Pacific Train Wreck, October 24, 1912, Eldon, Iowa
-
Description
-
Looking at a freight train wreck near Eldon, Iowa, on October 24, 1912. Construction of the Chicago and Rock Island Railroad began October 1, 1851, in Chicago, and the first train was operated on October 10, 1852, between Chicago and Joliet. Construction continued on through La Salle, and Rock Island was reached on February 22, 1854, becoming the first railroad to connect Chicago with the Mississippi River. Eldon had its start in the year 1870 by the building of the Keokuk and Des Moines Railway through that territory. Eldon was incorporated in 1872. 1912 postmark.
