Perturbations Observed In The Orbital Elements Of The Spectroscopic Binary 57 Cygni, Kenneth W. Mclaughlin, Janak Panthi
Perturbations Observed In The Orbital Elements Of The Spectroscopic Binary 57 Cygni, Kenneth W. Mclaughlin, Janak Panthi
Journal of the Iowa Academy of Science: JIAS
We present spectroscopy that confirms periodic Doppler-shifts along with photometry that reinforces a lack of eclipsing in the double-lined spectroscopic binary 57 Cygni. Our spectroscopy concentrates on a range encompassing H-alpha and the helium 667.8 nm line, where we find Doppler-shifts of both stars resolved in the helium line but less so in the broader H-alpha profile. Although we find the radial velocities derived from both lines reasonably consistent, we retained only the helium-line derived velocities for sinusoidal curve-fits to the orbital dependence. The fit-amplitudes specify the ratio of the stellar masses as 1.03 ± 0.05, in agreement with previous …

Herbaceous Vascular Flora Of Forested Seep Wetlands In Winneshiek County, Iowa, Usa, Elizabeth A. Lynch, Anna Burke Weckwerth
Herbaceous Vascular Flora Of Forested Seep Wetlands In Winneshiek County, Iowa, Usa, Elizabeth A. Lynch, Anna Burke Weckwerth
Journal of the Iowa Academy of Science: JIAS
Forested seep wetlands dominated by skunk cabbage (Symplocarpus foetidus) occur frequently in the Canoe Creek watershed of the Upper Iowa River, but this type of wetland has not been described systematically in the upper Midwest. The goal of this study is to document the herbaceous plant flora of five seeps. Although individual seeps are small (200-500 m2), they provide habitat for a high number of plant species. Five seeps with total area less than 0.2 ha supported more than 120 native vascular herbaceous taxa, 20 of which have a coefficient of conservatism (C-value) of 7 or …
A Statistical, Spatial, And Hydrologic Comparison Of Gauge-Based And Mpe-Based Rainfall Measurements, Richard Bernatz
A Statistical, Spatial, And Hydrologic Comparison Of Gauge-Based And Mpe-Based Rainfall Measurements, Richard Bernatz
Journal of the Iowa Academy of Science: JIAS
Gauge-based and multi-sensor precipitation estimation (MPE) data are compared on hourly, daily, monthly and event time scales at site locations over a 12-year period. Gauge data is collected at 16 sites within a 950 km2 portion of the Upper Iowa River in northeast Iowa. Average relative MPE bias is positive for all but the event time scale, and has a magnitude of less than 0.10 for all scales. Gauge and MPE average correlation coefficients range from 0.73 on the hourly scale to 0.92 on the event and monthly scales. The MPE relative bias standard deviation decreases from 1.70 mm on …

Ion Trap Mass Analyzer Apparatus, Methods, And Systems Utilizing One Or More Multiple Potential Ion Guide (Mpig) Electrodes, Curtiss Dwight Hanson
Ion Trap Mass Analyzer Apparatus, Methods, And Systems Utilizing One Or More Multiple Potential Ion Guide (Mpig) Electrodes, Curtiss Dwight Hanson
Patents (University of Northern Iowa)
In one aspect of the invention, an ion trap mass analyzer includes a variable- or multi-potential type ion guide (MPIG) assembly which has been pre-configured to produce a parabolic-type potential field. Each MPIG electrode has a resistive coating of designed characteristics. In one example the coating varies in thickness along the length of an underlying uniform substrate. The MPIG assembly can be a single MPIG electrode or an array of a plurality of MPIG electrodes. An array can facilitate delocalization for improved performance. This chemical modification of a uniform underlying substrate promotes cheaper and flexible instruments. The modified MPIG electrodes …
