Residual Properties And Almost Equicontinuity, Ethan Akin, Eli Glasner

Mathematics and Statistics Faculty Research & Creative Works

A property P of a compact dynamical system (X, f) is called a residual property if it is inherited by factors, almost one-to-one lifts and surjective inverse limits. Many transitivity properties are residual. Weak disjointness from all property P systems is a residual property provided P is a residual property stronger than transitivity. Here two systems are weakly disjoint when their product is transitive. Our main result says that for an almost equicontinuous system (X, f) with associated monothetic group Λ, (X, f) is weakly disjoint from all P systems if the only P systems upon which Λ acts are …

Low-Saturated-Fat Soybean Oil Reduces Saturated Fat In School Menus, J. M. Mahnken, S. F. Lutz, C. J. Anders, W. R. Fehr

Journal of the Iowa Academy of Science: JIAS

This study evaluated the impact of using low-saturated-fat soybean {Glycine max (L.) Merr.} oil on the saturated fat content of school menus. Seventy-six weekly menus were obtained from the Iowa Department of Education during School Meals Initiative reviews for the 1996-1997 school year. Three modifications were performed on school menus using the Nuttikids computer program: Low-saturated- fat (LSF) soybean oil replaced traditional vegetable oil in menu items; LSF soybean oil was substituted for traditional vegetable oil, solid fats, and egg yolks in recipes; and a menu simulation was conducted where oils and solid fats used in menu items were …

Species Specific Odds Of Occurrence Of Blackspot Among Fish From The Maple River In Western Iowa, John W. Mellen

Journal of the Iowa Academy of Science: JIAS

Odds ratio analysis was used to evaluate the relative likelihood of occurrence of blackspot (Neascus pyriformil, Chandler) infections among 14 species of fish collected from the Maple River in Buena Vista and Ida Counties in western Iowa. Prevalence estimates ranged from 0% to 47.4% with a mean prevalence of 11.9%. The rank ordering of odds ratios of infection allowed the species to be categorized as those with risks greater than, less than, and not different from average risk to infection within the Maple River sample. The species with the largest odds ratio was the bluntnose minnow, (Pimephales notatus) (odds ratio …

Expression Of Heterosis In Leaming And Midland Corn Belt Dent Populations, M. J. Carena, A. R. Hallauer

Journal of the Iowa Academy of Science: JIAS

Successful maize (Zea mays 1.) breeding programs are based on specific heterotic patterns. The Iowa Stiff Stalk Synthetic x Lancaster Sure Crop heterotic pattern is widely exploited in U.S. maize breeding programs. Alternative U.S. heterotic patterns have been suggested, but they have received limited attention and improvement. The objectives of this study were to evaluate cultivar crosses between Leaming and Midland Yellow Dent cultivars before and after inbred progeny selection and to assess their potential as an alternative U.S. heterotic pattern. Grain yield had a midparent heterosis value of 4.9% before selection and 17.8% in the third cycle of selection. …

Myxomycetes Of Big Bend National Park, Texas, Lois H. Tiffany, George Knaphus

Journal of the Iowa Academy of Science: JIAS

Seventy species of Myxomycetes have been collected directly in the field or observed later in the laboratory from field materials in moist chambers from Big Bend National Park, Texas. Collections were made over a 10 year period, 1989-1997 and 1999, during intensive seven-day fungus collecting trips to Big Bend in late September each year. McGraw (1968) in an earlier study of Texas Myxomycetes had reported 28 species from Big Bend, some of which were also found in this study. A total of 81 species are reported from the park. A variety of environmental conditions occurred during the 10 years with …

Longshore Sediment Transport As A Function Of Energy Dissipation, Ernest R. Smith, Ping Wang

Geology Faculty Publications

Experiments to measure waves, currents, and sediment transport rate for two breaker types, plunging and spilling, were conducted in a large-scale three-dimensional physical model. It was found that there was a large difference in cross-shore distribution and total sediment transport rate between the two breaker types. Total transport rates compared to existing predictive equations. The equations generally did not predict the data well. With the exception of the Kamphuis (1991) equation, which included a dependence on wave period, the predictive equations did not differentiate between breaker types.

Crack Detection In A Simply Supported Rc Beam Using Simplified Laplacian, H.A. Razak, S.L. Teng, Z. Ismail, A.G. Abdul Rahman

Research Publications (2000 to 2005)

This paper describes the detection and identification of cracking severity in a reinforced concrete beam using modal data. Experimental modal test was performed on the beam before and after application of load of increasing intensity to induce a single crack at a fixed location. Modal parameters extracted were categorised into two groups, namely local response parameter (mode shape data) and global response parameters. Localised changes such as cracking reduce the stiffness of the structure, and therefore caused a localised change in the discrete function of the mode shape. From a previous research, Laplacian Operator was initially proposed. However, when applied …

Detection Of Defects In Reinforced Concrete Beams Using Modal Data, Z. Ismail, H.A. Razak, Z. Ibrahim, A.G.A. Rahman, P.A. Hin

Research Publications (2000 to 2005)

A control reinforced beam and four reinforced concrete beams with various extent of defects in the form of voids and load-induced cracking were analyzed. Local flexural stiffness at each coordinate point was derived by substituting the regressed data at that point and using the centered-finite-divided-difference formula. The results of the first derivative of the local flexular stiffness for the reinforced concrete beams with voids were compared with those obtained from a similar beam with cracks in the middle. The results were also compared with a similar beam with cracks on the right side of the beam.

Other components such as power system model and analytical analysis are developed in-house. The tool is built by architecting component systems, which play a role in drawing a one-line diagram, capturing database, and performing analysis such as load flow, symmetrical and unsymmetrical faults. By using this approach, a more flexible …

Synthesis Of Cyclopropanes Via Organoiron Methodology: Preparation Of 2-(2′-Carboxy-3′-Ethylcyclopropyl)Glycine, Kamil Godula, William A. Donaldson

Chemistry Faculty Research and Publications

A route to 1,2,3-trisubstituted cyclopropanes has been developed. The relative stereochemistry at the three cyclopropane centers is established by nucleophilic attack on the pentadienyl ligand on the face opposite to iron and subsequent oxidatively induced reductive elimination with retention of configuration. This methodology was applied to the synthesis of 2-(2′-carboxy-3′-ethylcyclopropyl)glycines. The diastereomeric glycine dimethyl esters are separable as their diphenylmethylene imines.

The conformationally restricted glutamate analogs (2S,1′S,2′S,3′R)- and (2R,1′S,2′S,3′R)-ECCG's 5a and5b were prepared in five steps (17 and 15% yield, respectively) from (pentadienyl)Fe(CO) …
