Economic and Input-use Efficiency of Nitrogen Management Techniques in Non-irrigated Maize Production

The efficiency of nitrogen (N) management has become a main concern in agricultural cropping systems for understanding the optimal N rate to help producers improve economically and reduce the exhaustion of natural resources environmentally. Nitrogen rates vary both temporally and spatially by the interactions of the soil environment and rainfall through a growing season. Thus, a site-specific approach can further optimize this variability with the understanding of the role soil variability plays in the N rate applied to a non-irrigated field. The objective of this study was to evaluate the various nitrogen treatments for their nutrient use efficiency and economic measures depending on the timing of the treatments. The experimental design was arranged in a randomized complete block design. The nitrogen treatment rates are in the format of NH3_UAN as follows: 80_0, 120_0, 160_0, 200_0, 80_40, 80_80, and 80_120. For example, this reads as 80 lbs NH3_ 0 lbs of 32% UAN applied in the 80_0 treatment. Each treatment rate was also tested with an N stabilizer. The treatment plan also included zero N blocks through the design to serve as a control for the study. Equipment (i.e., precision ag) data of target N rate, applied N rates, and yield data were collected for further analysis of the relationship occurring between total N applied and yield per treatment plan. Normalized Difference Red-Edge (NDRE) reflectance measurements were also collected throughout the growing season to then be converted to geospatial imagery for analysis of crop stress, temporally and spatially throughout the field. In this specific field system, a lower rate of N treatment was economically favored. This indicated the soil had the presence of adequate mineralization prior to any application of N. For the additional rates of N to only yield less than 10 (bu/ac) more than the control would economically favor a lower rate of N for this specific field system

Bottom-Up Cubosome Synthesis Without Organic Solvents

This dataset contains processed SAXS data for mixtures of phytantriol with different diluents, and also following bottom-up synthesis of cubosomes. This data was collected to demonstrate the phase formations of phytantriol under different conditions.SAXS data was collected on an Anton-Parr SAXSpoint 2.0.SAXS data was collected on an Anton-Parr SAXSpoint 2.0, using an SDD of 556.9mm. The instrument is known to have a single dead pixel which sometimes results in an anomolous single-point peak

Understanding and Assessing Climate Change: Implications for Nebraska

This report was commissioned by the UNL Institute of Agriculture and Natural Resources (IANR) with the objective of evaluating and summarizing the existing scientific literature related to our changing climate. Scientists from the IANR’s School of Natural Resources and the Department of Earth and Atmospheric Sciences in the College of Arts and Sciences have been the principal contributors to the report under the able leadership of long-time, internationally leading applied climate scientist Professor Don Wilhite. Their efforts have resulted in a timely and seminal reference for state and local policy-makers, government agency leaders, private industry, and indeed all citizens of our great state. Globally, we face significant economic, social, and environmental risks as we confront the challenges associated with climate change. The body of scientific evidence confirms with a high degree of certainty that human activities in the form of increased concentrations of greenhouse gases (GHGs) since the beginning of the Industrial Revolution, changes in land use, and other factors are the primary cause for the warming that the planet has experienced, especially in recent decades. Is there a debate within the scientific community with regard to observed changes in climate and human activities as the principal causal factor? The short answer here is “no”, at least certainly not among climate scientists—that is, those scientists who have actual expertise in the study of climate and climate change. For more than a decade, there has been broad and overwhelming consensus within the climate science community that the human-induced effects on climate change are both very real and very large. The debate in 2014 is restricted to precisely how these changes will play out and what actions we will need to take to adapt to and mitigate the effects of these changes. The magnitude and rapidity of the projected changes in climate are unprecedented. The implications of these changes for the health of our planet, and the legacy we will leave to our children, our grandchildren and future generations are of vital concern. Therefore, it is imperative that we develop strategies now to adapt to the multitude of changes we are experiencing and will continue to experience in our climate. This process of adaptation must begin at the local level, where these changes are being observed and their impacts felt. However, global agreements on the reduction of GHG emissions are a critical part of the solution in terms of mitigating as much future warming as possible. The approach taken in this report is to review the voluminous scientific literature on the subject and interpret—given time and resource constraints—our current understanding of the science of climate change and the implications of projections of climate change for Nebraska. The goal of this report is to inform policy makers, natural resource managers, and the public about 1) the state of the science on climate change, 2) current projections for ongoing changes over the twenty-first century, 3) current and potential future impacts, and 4) the management and policy implications of these changes. Hopefully, this report will lead to a higher degree of awareness and the initiation of timely and appropriate strategic actions that enable Nebraskans to prepare for and adapt to current and future changes in our climate

Studienerfahrungen von Studenten im Abschlußjahr ihres 4jährigen Hochschulstudiums: Praktika und Diplomarbeit als Formen wissenschaftlich-produktiver Arbeit ; Forschungsbericht als Erstinformation zu SIL D 86

Mit diesem Forschungsbericht soll anhand einer Teilpopulation der "Studenten-Intervallstudie Leistung" (SIL) überwiegend Studenten, die 1986 ein vierjähriges Hochschulstudium abgeschlossen haben, über wesentliche Entwicklungsprozesse informiert werden. Insgesamt wurden 568 Studenten von 7 Universitäten und Hochschulen befragt. Die Autoren stellen Entwicklungstendenzen und Probleme heraus. Von besonderem Interesse ist das "wissenschaftlich-produktive Studium". Es geht u.a. um die Durchführung von Praktika und die Realisierung der Diplomarbeit. Weiterhin wird das Hochschullehrkräfte-Studenten-Verhältnis im letzten Studienjahr untersucht. (psz
