High-Energy Kink Observed In The Electron Dispersion Of High-Temperature Cuprate Superconductors, T. Valla, T. E. Kidd, W.-G. Yin, G. D. Gu, Z.-H. Pan, A. V. Fedorov
High-Energy Kink Observed In The Electron Dispersion Of High-Temperature Cuprate Superconductors, T. Valla, T. E. Kidd, W.-G. Yin, G. D. Gu, Z.-H. Pan, A. V. Fedorov
Faculty Publications
Photoemission studies show the presence of a high-energy anomaly in the observed band dispersion for two families of cuprate superconductors, Bi2Sr2CaCu2O8+δ and La2-xBaxCuO4. The anomaly, which occurs at a binding energy of approximately 340 meV, is found to be anisotropic and relatively weakly doping dependent. Scattering from short range or nearest neighbor spin excitations is found to supply an adequate description of the observed phenomena.

Weather Factors Influencing Winter Roosts Of American Crows In Central Iowa, Joshua D. Obrecht, Stephen J. Dinsmore
Weather Factors Influencing Winter Roosts Of American Crows In Central Iowa, Joshua D. Obrecht, Stephen J. Dinsmore
Journal of the Iowa Academy of Science: JIAS
We investigated the effects of season and weather on the winter roosting behavior of American Crows (Corvus brachyrhynchos) in central Iowa from January through March 2006. The peak number of birds recorded at a roost in Ames, Story County was 9,000+ in early February, and the number of individuals entering the roost decreased through February and March. Crows tended to enter the roost later in the day as winter neared completion. High wind speed and low light intensity caused individual to enter the roost earlier in the day. Temperature did not affect arrival time of crows. Wind speed, light intensity, …

Playing Games To Build Understanding, Michele Carnahan, Bridgette Stevens
Playing Games To Build Understanding, Michele Carnahan, Bridgette Stevens
Faculty Publications
I am fortunate. I teach from Investigations in Number, Data, and Space [TERC] (1996), a standards-based elementary mathematics curriculum. My evolution from teaching in a traditional teacher-centered approach to one that supports a student-centered community of learners has been a slow and gradual process during the past six years of teaching. Fortunately, through experience, professional development, and graduate level courses, I have come to appreciate the conceptual understanding students acquire from learning mathematics via a student-centered approach and how playing games is an effective instructional strategy for learning mathematics. As intended by the authors of Investigations and envisioned by the …

An Inventory Of The Vascular Flora Of Hamilton County, Iowa (2001-2004), Jimmie D. Thompson
An Inventory Of The Vascular Flora Of Hamilton County, Iowa (2001-2004), Jimmie D. Thompson
Journal of the Iowa Academy of Science: JIAS
A botanical survey of the vascular flora of Hamilton County, Iowa was conducted from 2001 to 2004. During this survey 973 taxa (761 native) were encountered. A search of the literature and a survey of Iowa State University's Ada Hayden Herbarium for additional documented specimens added 28 taxa to the flora. This total of 1001 taxa places Hamilton County fourth in vascular plant richness among inventories conducted in Iowa since 1950. A checklist including common names of most taxa, habitat and abundance data for all taxa encountered during the current survey is presented. Information on earlier collections includes source and …
Narrow Sense Heritability And Additive Genetic Correlations In Alfalfa Subsp. Falcata, Heathcliffe Riday, E. Charles Brummer
Narrow Sense Heritability And Additive Genetic Correlations In Alfalfa Subsp. Falcata, Heathcliffe Riday, E. Charles Brummer
Journal of the Iowa Academy of Science: JIAS
The complex genetics of autotetraploid alfalfa (Medicago sativa L.) make additive genetic variance component estimation difficult. Halfsib family variances often are used to estimate additive genetic variances and, by extension, narrow sense heritabilities and additive genetic correlations. These estimates contain a portion of the dominance variance. Using such calculations, in conjunction with parent-offspring covariance estimates, the dominance component can be separated from the additive genetic component. This is rarely done. This study reports average estimates across 30 populations, of both additive and dominance variance component estimates based on between halfsib family variance and parent-offspring covariance for biomass yield, plant height, …
Fall And Winter Food Habits Of Bobcats (Lynx Rufus) In Iowa, Kelcey J. Brockmeyer, William R. Clark
Fall And Winter Food Habits Of Bobcats (Lynx Rufus) In Iowa, Kelcey J. Brockmeyer, William R. Clark
Journal of the Iowa Academy of Science: JIAS
The bobcat (Lynx rufus) is a widely distributed native felid of North America but nearly disappeared from Iowa due to habitat loss and unregulated harvest that occurred during the century after European settlement. Bobcats are repopulating the state and are now relatively common in southern Iowa. This study was part of a research project to understand the ecology of the species in Iowa's landscape so that conservation plans could be established. We determined food habits by the examination of stomach contents from 100 bobcat carcasses that were accidentally killed in traps, killed by automobiles, or radio-marked individuals found dead during …

It’S Time For A Change, Storm Project
Open Educational Resources
Learning Objective: (adapted from the Secondary National Science Content Standards)
1 .Chemical reactions may release or consume energy. Some reactions, such as burning fossil fuels, release large amounts of energy by losing heat and emitting light.
2. Light can initiate many chemical reactions such as the evolution of urban smog.
3. The total energy of the universe is constant. Energy can be transferred by collisions in chemical reactions. However, it can never be destroyed.
4. Everything becomes less orderly over time. In energy transfer the overall effect of the energy spreads out uniformly like the warming of our surroundings as …
