Ec98-899 Sorghum Basis Patterns From Selected Sites In Nebraska Dec 2009

Ec98-899 Sorghum Basis Patterns From Selected Sites In Nebraska

University of Nebraska-Lincoln Extension: Historical Materials

The following publication contains the sorghum basis patterns for several towns in Nebraska. Price information was collected through surveys, newspapers, electronic media, etc. The listing includes towns representative of different geographic locations in Nebraska. The amount of data varies among locations. This publication will be updated each year by adding a year's data to each locations. This allows the user to observe the changing of basis patterns over time.

Encomium: Rolliin Harold Baker: 1916-2007, Carleton J. Phillips, Robert J. Baker, Hugh H. Genoways Oct 2009

Encomium: Rolliin Harold Baker: 1916-2007, Carleton J. Phillips, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Rollin H. Baker passed away on November 12, 2007, one day after reaching his 91st birthday. Rollin was a living legend, famous for his pioneering research on biogeography and natural history of Mexican mammals, especially rodents, for his contributions to the understanding of Michigan mammals, and for being a mentor and friend to all young, aspiring mammalogists. Rollin Baker’s career lasted way beyond his traditional retirement, and in his final months he was still active in the Texas Society of Mammalogists and in conservation issues in Texas. Indeed, when he was 89 years old he presented a guest lecture in …

Modeling And Analysis Of Biological Populations, Joan Lubben Jul 2009

Modeling And Analysis Of Biological Populations, Joan Lubben

Department of Mathematics: Dissertations, Theses, and Student Research

Asymptotic and transient dynamics are both important when considering the future population trajectory of a species. Asymptotic dynamics are often used to determine whether the long-term trend results in a stable, declining or increasing population and even provide possible directions for management actions. Transient dynamics are important for estimating invasion speed of non-indigenous species, population establishment after releasing biocontrol agents, or population management after a disturbance like fire. We briefly describe here the results in this thesis.

(1) We consider asymptotic dynamics using discrete time linear population models of the form n(t + 1) = An(t) where …

Drug Release And Its Relationship With Kinetic And Thermodynamic Parameters Of Drug Sorption Onto Polylactide, Starch Acetate, Wheat Gluten And Soy Protein Fibers, Weijie Xu Mar 2009

Drug Release And Its Relationship With Kinetic And Thermodynamic Parameters Of Drug Sorption Onto Polylactide, Starch Acetate, Wheat Gluten And Soy Protein Fibers, Weijie Xu

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Drug release and its relationship with kinetic and thermodynamic parameters of drug sorption onto biodegradable and biocompatible fibers made of polylactic acid (PLA), starch acetate (SA), wheat gluten (WG) and soy protein (SP) have been studied using Diclofenac, 5 Fluorouracil (5-Fu) and Metformin as drug models. To understand drug release from these four fibers using sorption, kinetic and thermodynamic parameters, such as the diffusion coefficient, activation energy for diffusion, affinity, and sorption enthalpy and entropy, have been investigated. Quantitative relationship between drug release and drug loading concentration, affinity, and activation energy for diffusion was established to predict initial bursts and …

Using The World Wide Web To Educate And Inform The Public About Risk And Agricultural Biotechnology, Douglas A. Golick, Robert D. Peterson, Leon G. Higley Jan 2009

Using The World Wide Web To Educate And Inform The Public About Risk And Agricultural Biotechnology, Douglas A. Golick, Robert D. Peterson, Leon G. Higley

Department of Entomology: Faculty Publications

The University of Nebraska and AgBios, Inc. launched the AgBiosafety website (http://agbiosaftzy.unl.edu) with the purpose of educating the public about agricultural biotechnology risk and safezy issues through science-based content. This article discusses the creation ofthe website, its components, and data gathered from usage statistics and a web-delivered survey. Also included is a discussion of the results ofdata gathered and recommendations for future web-based educational efforts in biotechnology safety and risk assessment.

Farming Systems Education: Case Study Of Swedish Test Pilots, Lennart Salomonsson, Anna Nilsson, Sofia Palmer, Adam Roigart, Charles A. Francis Jan 2009

Farming Systems Education: Case Study Of Swedish Test Pilots, Lennart Salomonsson, Anna Nilsson, Sofia Palmer, Adam Roigart, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

We describe and analyze a pedagogical experiment that introduced a broad and holistic perspective on complete farming systems, systemic learning tools, and a participatory learning strategy at an early stage in agronomy education. The paper describes the adventure of three students, who came from a conventional agronomy program at the Swedish University of Agricultural Sciences (SLU), who were frustrated with the lack of integrated approaches to the study of agricultural systems and a strong focus on molecular-level processes in their first year of education. They encountered a narrow focus in most courses and the overall curricula of agricultural education that …

Ec09-130 2009 Guide For Weed Management, Mark L. Bernards, Roch E. Gaussoin, Robert N. Klein, Stevan Z. Knezevic, Drew J. Lyon, Lowell D. Sandell, Robert G. Wilson Jr., Patrick J. Shea, Clyde Ogg Jan 2009

Ec09-130 2009 Guide For Weed Management, Mark L. Bernards, Roch E. Gaussoin, Robert N. Klein, Stevan Z. Knezevic, Drew J. Lyon, Lowell D. Sandell, Robert G. Wilson Jr., Patrick J. Shea, Clyde Ogg

University of Nebraska-Lincoln Extension: Historical Materials

The 2009 Guide for Weed Management in Nebraska is a valuable tool for anyone with responsibility for controlling weeds in crop, pasture, range, turf or aquatic environments in Nebraska. Our goal is to provide a comprehensive publication that will enable the user to make sound weed control decisions based on unbiased, research-based information, and to carry out weed control activities in a safe and responsible manner.

This publication deals principally with herbicides as an aid for crop production. The suggestions for use are based on research at the University of Nebraska–Lincoln Research and Extension Centers and elsewhere.
