The webvolution’s impact on vocational classrooms and administration

We are eyewitnesses of a Webvolution; a revolution brought about by the explosion of the Internet and the World Wide Web (WWW). Few innovations have been embraced more quickly than the Internet. The current trend of the Internet will change the face of education, as we know it. Almost every public school in the United States has Internet access and other countries are adopting these technologies at a rapid pace. The Internet is perhaps the first truly global environment. This paper will explore the potential of utilizing the WWW as a resource for vocational classrooms and administration. It provides informative information on such topics as: (1) true cost of information technology ownership; (2) using an Application Service Provider (ASP); (3) using the Internet as a communication tool; (4) data security issues; and (5) fundamental changes in the infrastructure requirements of information technology

Ice Initiation by Aerosol Particles: Measured and Predicted Ice Nuclei Concentrations versus Measured Ice Crystal Concentrations in an Orographic Wave Cloud

The initiation of ice in an isolated orographic wave cloud was compared with expectations based on ice nucleating aerosol concentrations and with predictions from new ice nucleation parameterizations applied in a cloud parcel model. Measurements of ice crystal number concentrations were found to be in good agreement both with measured number concentrations of ice nuclei feeding the clouds and with ice nuclei number concentrations determined from the residual nuclei of cloud particles collected by a counterflow virtual impactor. Using lognormal distributions fitted to measured aerosol size distributions and measured aerosol chemical compositions, ice nuclei and ice crystal concentrations in the wave cloud were reasonably well predicted in a 1D parcel model framework. Two different empirical parameterizations were used in the parcel model: a parameterization based on aerosol chemical type and surface area and a parameterization that links ice nuclei number concentrations to the number concentrations of particles with diameters larger than 0.5 μm. This study shows that aerosol size distribution and composition measurements can be used to constrain ice initiation by primary nucleation in models. The data and model results also suggest the likelihood that the dust particle mode of the aerosol size distribution controls the number concentrations of the heterogeneous ice nuclei, at least for the lower temperatures examined in this case

Evaluation of Foliar Fungicides on Soybeans in 2018

Soybean foliar fungicides were evaluated for foliar disease management and yield response across seven Iowa State University research and demonstration farms in 2018. These included the Northwest Research and Demonstration Farm(Sutherland), Northern Research and Demonstration Farm (Kanawha), Northeast Research and Demonstration Farm(Nashua), Central Iowa Research Farms (Ames), Armstrong Memorial Research and Demonstration Farm (Lewis), McNay Memorial Research and Demonstration Farm (Chariton), and Southeast Research and Demonstration Farm(Crawfordsville)
