Linking Water Quality Improvement with Economic Benefits to the Iowa Population

The Iowa Nutrient Reduction Strategy (INRS) establishes a goal of reducing nutrient discharge by 45% to Iowa streams and water bodies by 2035 (IDALS 2020), consistent with the nutrient reduction goal reported in the Gulf Hypoxia Action Plan (MRGMWN Task Force 2008). The INRS also embraced an interim Hypoxia Task Force goal to reduce nutrient losses 20% by 2025 (IDALS 2020). However, formidable challenges remain to attaining these goals as evidenced by pervasive elevated in-stream nitrogen (N) and phosphorus (P) levels in Iowa streams reported by Jones et al. (2018a; 2018b; 2019) and Schilling et al. (2020). Algal blooms have also been increasing in Iowa lakes and rivers, resulting in eutrophication, fish-kills, and harmful impacts on drinking water supplies, outdoor recreation, and tourism (IEC 2023; INRS 2023; Christianson et al. 2013). Mitigation of the seasonal hypoxic zone in the northern Gulf of Mexico, which is driven by nutrient export from the Mississippi River, has also proved elusive (Rabalais and Turner 2019)

Asymmetric Ramsey properties of random graphs involving cliques and cycles

We prove that for every ℓ, r ≥ 3, there exists c > 0 such that for (image found), with high probability there is a 2-edge-colouring of the random graph Gn,p with no monochromatic copy of Kr of the first colour and no monochromatic copy of Cℓ of the second colour. This is a progress on a conjecture of Kohayakawa and Kreuter

Reliability prediction for structures under cyclic loads and recurring inspections

This work presents a methodology for determining the reliability of fracture control plans for structures subjected to cyclic loads. It considers the variability of the parameters involved in the problem, such as initial flaw and crack growth curve. The probability of detection (POD) curve of the field non-destructive inspection method and the condition/environment are used as important factors for structural confidence. According to classical damage tolerance analysis (DTA), inspection intervals are based on detectable crack size and crack growth rate. However, all variables have uncertainties, which makes the final result totally stochastic. The material properties, flight loads, engineering tools and even the reliability of inspection methods are subject to uncertainties which can affect significantly the final maintenance schedule. The present methodology incorporates all the uncertainties in a simulation process, such as Monte Carlo, and establishes a relationship between the reliability of the overall maintenance program and the proposed inspection interval, forming a “cascade” chart. Due to the scatter, it also defines the confidence level of the “acceptable” risk. As an example, the damage tolerance analysis (DTA) results are presented for the upper cockpit longeron splice bolt of the BAF upgraded F-5EM. In this case, two possibilities of inspection intervals were found: one that can be characterized as remote risk, with a probability of failure (integrity nonsuccess) of 1 in 10 million, per flight hour; and other as extremely improbable, with a probability of nonsuccess of 1 in 1 billion, per flight hour, according to aviation standards. These two results are compared with the classical military airplane damage tolerance requirements
