An investigation of the theory of the dispersion formula for nuclear reactions
(University of Kansas, 1949-08-31)The purpose of this investigation is to gain insight into the theory of nuclear structure and the theory of resonances in scattering processes. -
Methodological considerations of microdialysis sampling for determination of cerebral basal glucose concentration in extracellular space of freely moving rat
(University of Kansas, 1998-05-31)In the recent past there has been a controversy about the basal glucose levels in the brain of freely moving rats. Kinetic rate constants and transport parameters across the blood brain barrier and in the brain tissue ... -
The Catholic Bohemian German dialect of Ellis, Kansas
(University of Kansas, 1998-05-31)Beginning in the 1880s, many German speaking immigrants left the Austrian settlements in Bukovina for the United States. The Bukovina immigrants to the Ellis area in west central Kansas formed two distinct groups in Ellis. ... -
MO02 Lafayette County, Missouri
(1995)Wenker sentences and an anecdote recorded in 1995 for the West Low German dialect of Concordia, MO. Female speaker born in 1912. -
The printing of Shakespeare's Titus Andronicus, 1594

Activating dinitrogen for chemical looping ammonia Synthesis: Mn nitride layer growth modeling
(Chemical Engineering Science, 2022-04-28)The earth-abundant transition metal manganese (Mn) has been shown to activate dinitrogen (N2) and store nitrogen (N) as nitride for subsequent chemical reaction, for example, to produce ammonia (NH3). Chemical looping ... -
Activating dinitrogen for chemical looping ammonia synthesis: nitridation of manganese
(Journal of Materials Science, 2021-04-23)The earth-abundant transition metal manganese (Mn) has been shown to be useful to activate dinitrogen at atmospheric pressure and elevated temperature by forming bulk Mn nitrides. Mn nitrides could then be used, for example, ... -
Relating agriculture, energy, and water decisions to farm incomes and climate projections using two freeware programs, FEWCalc and DSSAT
(Agricultural Systems, 2021-10)Context: The larger scale perspective of Integrated Assessment (IA) and smaller scale perspective of Impacts, Adaptation, and Vulnerability (IAV) need to be bridged to design long-term solutions to agricultural problems ... -
Consequences of climate change on food-energy-water systems in arid regions without agricultural adaptation, analyzed using FEWCalc and DSSAT
(Resources, Conservation and Recycling, 2021-05)Effects of a changing climate on agricultural system productivity are poorly understood, and likely to be met with as yet undefined agricultural adaptations by farmers and associated business and governmental entities. The ... -
Chemical Looping of Manganese to Synthesize Ammonia at Atmospheric Pressure: Sodium as Promoter
(Chemical Engineering & Technology, 2020-08-10)Affordable synthetic ammonia (NH3) enables the production of nearly half of the food we eat and is emerging as a renewable energy carrier. Sodium-promoted chemical looping NH3 synthesis at atmospheric pressure using manganese ... -
Beyond fossil fuel–driven nitrogen transformations
(Science, 2018-05-25)How much carbon does it take to make nitric acid? The counterintuitive answer nowadays is quite a lot. Nitric acid is manufactured by ammonia oxidation, and all the hydrogen to make ammonia via the Haber-Bosch process comes ... -
Towards sustainable agriculture: Fossil-free ammonia
(Journal of Renewable and Sustainable Energy, 2016-12-28)About 40% of our food would not exist without synthetic ammonia (NH3) for fertilization. Yet, NH3 production is energy intensive. About 2% of the world's commercial energy is consumed as fossil fuels for NH3 synthesis based ... -
Legitimate to whom? The challenge of audience diversity and new venture legitimacy
(Journal of Business Venturing, 2017-01)We examine how entrepreneurs manage new venture legitimacy judgments across diverse audiences, so as to appear legitimate to the different audience groups that provide much needed financial resources for venture survival ... -
The role of network density and betweenness centrality in diffusing new venture legitimacy: an epidemiological approach
(International Entrepreneurship and Management Journal, 2017)To survive and grow, new ventures must establish initial legitimacy, and subsequently diffuse this legitimacy through a given population. While the notion of initial legitimacy has received substantial attention in the ... -
Regulating the Ogallala: Paradox and Ambiguity in Western Kansas
(The Economics of Ecology, Exchange, and Adaptation: Anthropological Explorations, 2016-09-01)Purpose: To illuminate the underlying logic of western Kansas farmers’ decisions to irrigate at unsustainable rates and the state’s regulatory policies and practices that enable depletion of the Ogallala aquifer. Meth ... -
Economic feasibility of algal biodiesel under alternative public policies
(Renewable Energy, 2014-07)The motivation for this research was to determine the influence of public policies on economic feasibility of producing algal biodiesel in a system that produced all its energy needs internally. To achieve this, a steady-state ... -
Actor–Networks, Farmer Decisions, and Identity
(Culture, Agriculture, Food and Environment, 2013)Climate change and industrial agricultural practices pose threats to the future of Kansas agriculture. To inform the debate about sustainable agriculture that must soon occur, we seek to illuminate the factors involved in ... -
Solar thermochemical production of ammonia from water, air and sunlight: Thermodynamic and economic analyses
(Energy, 2012-06)Ammonia is an important input into agriculture and is used widely as base chemical for the chemical industry. It has recently been proposed as a sustainable transportation fuel and convenient one-way hydrogen carrier. ... -
Sustainability of algae derived biodiesel: A mass balance approach
(Bioresource Technology, 2011-01)A rigorous chemical engineering mass balance/unit operations approach is applied here to bio-diesel from algae mass culture. An equivalent of 50,000,000 gallons per year (0.006002 m3/s) of petroleum-based Number 2 fuel ...
