Concrete Pavement Mixture Design and Analysis (MDA): Development and Evaluation of Vibrating Kelly Ball Test (VKelly Test) for the Workability of Concrete, 2015

Due to the low workability of slipform concrete mixtures, the science of rheology is not strictly applicable for such concrete. However, the concept of rheological behavior may still be considered useful. A novel workability test method (Vibrating Kelly Ball or VKelly test) that would quantitatively assess the responsiveness of a dry concrete mixture to vibration, as is desired of a mixture suitable for slipform paving, was developed and evaluated. The objectives of this test method are for it to be cost-effective, portable, and repeatable while reporting the suitability of a mixture for use in slipform paving. The work to evaluate and refine the test was conducted in three phases: 1. Assess whether the VKelly test can signal variations in laboratory mixtures with a range of materials and proportions 2. Run the VKelly test in the field at a number of construction sites 3. Validate the VKelly test results using the Box Test developed at Oklahoma State University for slipform paving concrete The data collected to date indicate that the VKelly test appears to be suitable for assessing a mixture’s response to vibration (workability) with a low multiple operator variability. A unique parameter, VKelly Index, is introduced and defined that seems to indicate that a mixture is suitable for slipform paving when it falls in the range of 0.8 to 1.2 in./√s.

Investigation of Maquoketa's Pit Bull Ban Ordinance and Enforcement, 2006

Case File 0603634 On September 13, 2006, Kelly Wilslef submitted a complaint to the Ombudsman about the Maquoketa City Council (Council). Ms. Wilslef stated a Maquoketa police officer served her an abatement notice for violating the city ordinance preventing owners from keeping pit bull terrier dogs in the city. The Council subsequently determined her dog was a pit bull mix, and ordered her to remove the dog from the city. Ms. Wilslef claimed the Council unreasonably relied on non-expert testimony supporting the city’s position her dog was a pit bull mix. She further claimed that if her dog was in fact a pit bull mix, the city ordinance did not apply to mixed-breed pit bulls; therefore, the Council acted contrary to law when it concluded she violated the city ordinance and ordered her to remove her dog from the city.

Pieces of Iowa’s Past, January 18, 2012

Pieces of Iowa’s Past, published by the Iowa State Capitol Tour Guides weekly during the legislative session, features historical facts about Iowa, the Capitol, and the early workings of state government. All historical publications are reproduced here with the actual spelling, punctuation, and grammar retained. January 18, 2012 THIS WEEK: Report by Annie Wittenmyer, State Sanitary Agent BACKGROUND: The 10th General Assembly convened on January 11, 1864, and adjourned on March 29—a 79-day session. There were 138 members in the legislature. The members included 42 Republicans in the Senate and 87 Republicans in the House of Representatives. Democrats numbered four in the Senate and five in the House. Jacob Butler was the Speaker of the House, and Enoch W. Eastman was the Lt. Governor presiding in the Senate. William Stone was Iowa’s governor. Stone was inaugurated on January 14, 1864. He was 36 years old. Governor Stone, a friend of President Abraham Lincoln, rode Lincoln’s funeral train to Springfield, Illinois
