The cereal leaf beetle in Iowa oats: Research and education program for biological control and sustainable management practices

The cereal leaf beetle, (Oulema melanopusj, a serious insect pest of small grains, including oats, was detected in the eastern half of Iowa in the early 1990s. Iowa\u27s five leading counties for oat production are located in northeastern Iowa, and field surveys were conducted in this area to document Entomology the levels of cereal leaf beetle infestations, potential impact on production, and the presence of natural enemies. Findings showed that current cereal leaf beetle numbers are too low to cause economic damage and no compelling need exists to establish a management program aimed against this particular pes

The Legality and Morality of Using Deadly Force to Protect Unborn Children from Abortionists

Is killing abortionists as they arrive at abortuaries to perform regularly scheduled abortions a legally justifiable use of force in defense of another person\u27s life? Under commonly accepted criminal law principles of justification, a person normally is entitled to use force—even deadly force—when necessary to save a person\u27s life from an aggressor bent on taking that life. But because Roe and its progeny have made abortion a constitutionally protected right, courts would predictably hold that using force against an abortionist is not legally justified, despite the fact that the motive for that force is to defend innocent human life. Even if intentionally killing an abortionist can be legally justified, is it morally justified? Roman Catholics apply Catholic moral teaching to this question. That teaching embodies universal moral principles that are useful to anybody—Catholic or non-Catholic—who cares to analyze the moral issue. Based on Catholic moral teaching, intentionally killing abortionists as Griffin and Hill did is morally wrong, at least at a time when we are not in a state of justified rebellion. For now, there are alternatives to violence—particularly prayer and the uncompromising proclamation of the truth about abortion—that are more appropriate, prudent, and in the long run, effective than escalating the violence that abortionists, spurred by the Supreme Court, have started

Placing Confidence Limits on Polarization Measurements

The determination of the true source polarization given a set of measurements is complicated by the requirement that the polarization always be positive. This positive bias also hinders construction of upper limits, uncertainties, and confidence regions, especially at low signal-to-noise levels. We generate the likelihood function for linear polarization measurements and use it to create confidence regions and upper limits. This is accomplished by integrating the likelihood function over the true polarization (parameter space), rather than the measured polarization (data space). These regions are valid for both low and high signal-to-noise measurements.Comment: 8 pages, 3 figures, 1 table, submitted to PAS

Applying X-ray Imaging Crystal Spectroscopy for Use as a High Temperature Plasma Diagnostic

X-ray spectra provide a wealth of information on high temperature plasmas; for example electron temperature and density can be inferred from line intensity ratios. By using a Johann spectrometer viewing the plasma, it is possible to construct profiles of plasma parameters such as density, temperature, and velocity with good spatial and time resolution. However, benchmarking atomic code modeling of X-ray spectra obtained from well-diagnosed laboratory plasmas is important to justify use of such spectra to determine plasma parameters when other independent diagnostics are not available. This manuscript presents the operation of the High Resolution X-ray Crystal Imaging Spectrometer with Spatial Resolution (HIREXSR), a high wavelength resolution spatially imaging X-ray spectrometer used to view hydrogen- and helium-like ions of medium atomic number elements in a tokamak plasma. In addition, this manuscript covers a laser blow-off system that can introduce such ions to the plasma with precise timing to allow for perturbative studies of transport in the plasma.

Revisiting an integrated approach to bean leaf beetle and bean pod mottle virus management

This article originally appeared in the 2005 ICM newsletter. However, the significance of the bean leaf beetle and bean pod mottle virus has not diminished in recent years. There is still the potential of economic damage from either or both pests. We have recently completed a three-year study that examines the complex issues of managing these two pests, but the data are still being analyzed. We also have identified potential field tolerance to virus disease. Growers are encouraged to query seed dealers regarding tolerance of varieties to virus disease. Ultimately, this will likely be the best management tool for disease control. In the meantime, we give you our best recommendations as we understand the situation in Iowa

Recent bean leaf beetle and bean pod mottle virus research

Soybean growers face a dilemma when considering management options for bean leaf beetles and bean pod mottle virus. Rayda Krell recently completed a research program at Iowa State University that focused on immediate solutions for this pest problem. This article summarizes her research from which we suggest some short-term management options
