The Electoral College in the American Mind Dataset, September 13-17, 2024
The dataset was generated by a study titled “The Electoral College in the American Mind,” the purpose of which was to better understand people’s thoughts and feelings about the Electoral College. The study’s survey instrument was a questionnaire that posed thirty Electoral College-themed questions: twenty-eight of the questions were written in a multiple-choice format; two were written in an open-ended format. The dataset consists of the aggregate responses to the former, cross-tabulated by the respondents’ demographic characteristics.
The study was administered online by a national firm, SurveyUSA, from September 13, 2024, through September 17, 2024. Using a web-based format, SurveyUSA administered the study’s questionnaire to 1,500 adults in the United States, using a non-probability sample provided by Lucid Holdings LLC of New Orleans. The pool of adult survey respondents was weighted to US Census American Community Survey targets for gender, age, race, education, and home ownership
Infographic | SEAL!ND Reach and Impact in 2024-2025
Over the past decade, the North Dakota Health & Human Services Oral Health Program (OHP) has completed more than 23,000 student visits through SEAL!ND, a statewide school-based sealant program that brings preventive dental care directly into schools. In 2024–25, SEAL!ND reached 69 schools across North Dakota, providing dental screenings, sealants, fluoride varnish applications, oral health education, and referrals to students who might otherwise lack access to care
United Hospital on Columbia Road North in the early 1970s
A view from Columbia Road looking southwest toward the United Hospital in the early 1970s. The large brick building has five main floors, with a smaller sixth floor above the central entryway. The roof has three tall chimneys, and a concrete cross atop the sixth floor. A line of vehicles are parked in the front driveway, around a lawn with short, leafless trees.https://commons.und.edu/gf-herald-photos/1014/thumbnail.jp
Response Surface Analysis of Biopolymer Gel Performance in Fractured High Temperature Formations
This study investigates the performance of a hydroxyethyl cellulose (HEC)–based biopolymer gel for fracture conformance control in high-temperature geothermal reservoirs using a statistically driven experimental framework. Laboratory core-flooding experiments were conducted on fractured limestone and sandstone samples from the Deadwood Formation under controlled thermal and chemical conditions, with temperatures reaching 160 °C. The effects of temperature, gel formulation salinity, and lithology on key performance indicators—including residual resistance factor (RRF), resistance factor (RF), gel extrusion pressure gradient (GEPG), and heat retention—were quantified. Response Surface Methodology (RSM) was applied using Minitab to capture variable interactions and develop predictive models for gel behavior under geothermal conditions. Results indicate strong thermal and chemical resilience of the HEC-based gel, particularly in limestone cores, where RRF values exceeded 10⁸ and heat retention approached 80% at elevated temperatures. The statistical models highlight the dominant influence of lithology and salinity on treatment effectiveness and provide a practical framework for optimizing gel-based conformance treatments in fractured geothermal systems
Governors Guy and Williams, undated
Undated group photograph of (left to right) North Dakota Governor Bill Guy, Michigan Governor G. Mennen Williams, Raymond Vendsel, Mary Lanier, and Walter Lanier (from back of photograph). Williams was likely in North Dakota to campaign for Vendsel, who was an unsuccessful candidate for the U.S. House of Representatives in 1954 and the U.S. Senate in 1958.https://commons.und.edu/nd-politics-photos/1568/thumbnail.jp
Using TinyLev acoustic levitator at low temperatures to generate atmospheric ice crystals (obstacles to hypersonic flights)
Atmospheric clouds contain supercooled water droplets, frozen droplets, and ice crystals ranging in size from a few nm to 100’s of µm. These elements form crystal chain aggregates of varying lengths, though their aggregation process remains unknown. Hypersonic flights, which travel at speeds at least five times faster than sound, gain excessive momentum. As a result, tiny atmospheric ice crystal aggregates can cause damage to the vehicle’s nose cone and exterior. However, these atmospheric ice crystals are not well studied and require advanced laboratory facilities for analysis. At the Aerosol Engineering Lab at UND, atmospheric ice crystals are generated using a TinyLev acoustic levitator combined with liquid nitrogen (N₂). These ice crystals are produced to drop in front of the shockwave (inside Purdue’s 3-inch shock tube) to study their behavior in a hypersonic environment. This research also contributes to a deeper understanding of climate science and global atmospheric models.https://commons.und.edu/grad-posters/1011/thumbnail.jp
Senator Burdick with two pilots at the Minot Air Force Base
(From back of photograph): Minot AFB, North Dakota...U.S. Senator Quentin N. Burdick (Dem., N. Dak., center) with Lt. Colonel Jacksel M. Broughton, 5th Fighter Interceptor Squadron Commander (right) and Captain Lawrence C. Huseman of the interceptor unit. Senator Burdick visited the squadron on April 27th in conjunction with a tour of the Minot Air Force Base. Colonel Broughton held a briefing and tour of the squadron and scrambled an F-106 for the Senator and his party.
The son of Representative Usher Burdick, Quentin Burdick represented North Dakota in the United States House of Representatives from 1958 to 1960 and the United States Senate from 1960 until his death in 1992.https://commons.und.edu/nd-politics-photos/1590/thumbnail.jp

Signing Autographs for the Fans!
Deputy State Treasurer Robert Hanson signs an inflatable donkey. Governor Art Link previously signed the item. Robert Hanson served as State Treasurer from 1979 until 1980 and from 1985 until 1992. He was also the North Dakota Tax Commissioner from 1993 to 1996.https://commons.und.edu/nd-politics-photos/1621/thumbnail.jp
