Effect Of External Energy On The Atomic, Crystalline, And Powder Characteristics Of Antimony And Bismuth Powders, Mahendra Kumar Trivedi Sep 2099

Effect Of External Energy On The Atomic, Crystalline, And Powder Characteristics Of Antimony And Bismuth Powders, Mahendra Kumar Trivedi

Mahendra Kumar Trivedi

Next to atoms and molecules the powders are the smallest state of matter available in high purities and large quantities. The effect of any external energy on the shape, morphology and structure can thus be studied with relative ease. The present investigation deals with the effect of a non-contact external energy on the powders of antimony and bismuth. The characteristics of powders treated by external energy are compared with the as received powders (control). The average particle sizes, d50 and d99, the sizes below which 99% of the particles are present showed significant increase and decrease indicating that the energy ...

Stability Analysis Of Kernel Quality Traits In Exotic-Derived Doubled Haploid Maize Lines, Adam Vanous, Candice Gardner, Michael Blanco, Adam Martin-Schwarze, Jinyu Wang, Xianran Li, Alexander E. Lipka, Sherry Flint-Garcia, Martin Bohn, Jode Edwards, Thomas Lubberstedt

Agronomy Publications

Variation in kernel composition across maize (Zea mays L.) germplasm is affected by a combination of the plant’s genotype, the environment in which it is grown, and the interaction between these two elements. Adapting exotic germplasm to the US Corn Belt is highly dependent on the plant’s genotype, the environment where it is grown, and the interaction between these components. Phenotypic plasticity is ill-defined when specific exotic germplasm is moved over large latitudinal distances and for the adapted variants being created. Reduced plasticity (or stability) is desired for the adapted variants, as it allows for a more rapid ...

Risks And Opportunities Of Gm Crops: Bt Maize Example, Andrea K. Carzoli, Siddique I. Aboobucker, Leah L. Sandall, Thomas T. Lubberstedt, Walter P. Suza

Agronomy Publications

The anticipated world population growth emphasizes a need to produce more food on less land. Cutting-edge technologies, including genetic engineering, can help to develop improved crop varieties and protect natural resources. In spite of the potential for genetically-modified (GM) crops to make crop production more efficient, they remain a polarizing issue due to safety concerns. This paper provides an overview of the risk assessment process. The safety of Bacillus thuringiensis (Bt) proteins is used as an example for how risk assessment is applied to GM crops. Risks associated with GM crops have proven to be low to non-existent. Developing countries ...

Analyzing Large Workers’ Compensation Claims Using Generalized Linear Models And Monte Carlo Simulation, Fatemeh Davoudi Kakhki, Steven A. Freeman, Gretchen A. Mosher

Agricultural and Biosystems Engineering Publications

Insurance practitioners rely on statistical models to predict future claims in order to provide financial protection. Proper predictive statistical modeling is more challenging when analyzing claims with lower frequency, but high costs. The paper investigated the use of predictive generalized linear models (GLMs) to address this challenge. Workers’ compensation claims with costs equal to or more than US$100,000 were analyzed in agribusiness industries in the Midwest of the USA from 2008 to 2016. Predictive GLMs were built with gamma, Weibull, and lognormal distributions using the lasso penalization method. Monte Carlo simulation models were developed to check the performance ...

Fiscal Reform Scenarios And Accessibility 2018.08.20.Docx, Guillermo Fernandez Nov 2018

Fiscal Reform Scenarios And Accessibility 2018.08.20.Docx, Guillermo Fernandez

Guillermo Fernandez

Since signing the peace accords in 1996, the Guatemalan government committed to increase the tax burden of 1995 by 50% to a total of 13%. This target has only been reached 4 times in more than two decades. There have been multiple attempts at tax reforms that have failed or been incomplete. Guatemala exhibits much income inequality and is one of the poorest countries in the region.  
Given this background, the problem to be considered in this analysis is that there is little information regarding how different tax reforms would affect the accessibility to food in Guatemala. With information regarding ...


Profitability Of Developing Beef Heifers On Stockpiled Winter Forages, Zachary David Mcfarlane, Chris Boyer, J. Travis Mulliniks Nov 2018

Profitability Of Developing Beef Heifers On Stockpiled Winter Forages, Zachary David Mcfarlane, Chris Boyer, J. Travis Mulliniks

Journal of Applied Farm Economics

We estimate the profitability of developing heifers on one stockpiled cool-season grass and two stockpiled warm-season grasses during the winter months by comparing distributions of net present value (NPV) over an 11-year useful life. Furthermore, distributions of payback period and the break-even price for each calf over the heifer’s production life were generated for each forage species. These results are compared across forages as well as to a simulated drylot system for heifer development. Data comes from a grazing experiment in Tennessee, where heifers grazed big bluestem and Indian grass combination (BBIG), switchgrass (SW), or endophyte-infected tall fescue (TF ...

Utilizing Municipal Compost And Equine Stall Waste As Potential Economic Alternatives In An In-Ground Pot-In-Pot Production System, Ashley Robert, Alyx Shultz Nov 2018

Utilizing Municipal Compost And Equine Stall Waste As Potential Economic Alternatives In An In-Ground Pot-In-Pot Production System, Ashley Robert, Alyx Shultz

Posters-at-the-Capitol

For Western Kentucky farmers, one viable income source could be a pot-in-pot nursery production. One of the highest costs of production in this system was the planting media that the plants were grown in. Economical alternatives to high-priced, non-renewable peat-based mixes were important to consider. Unique to this region, were two renewable soil amendments that may help farmers to widen their profit margin in a pot-in-pot system. This research looked at the economic viability of locally sourced horse stall waste and municipal compost as soil amendments to a traditional bark and peat based mix. Initial cost projections were favorable for ...


Assessing Water Policy Implications Of The Changing Agriculture In New Mexico, Trevor A. Birt Nov 2018

Assessing Water Policy Implications Of The Changing Agriculture In New Mexico, Trevor A. Birt

Shared Knowledge Conference

Agriculture is the dominant water sector in New Mexico, responsible for more than 80% of water withdrawals in 2015 (USGS 2018). Water policy needs to be extremely adaptive and informed to meet the needs of not only farmers, but cities, industry and riparian uses. Since 1840, the U.S. Department of Agriculture (USDA) has conducted census surveys assessing all levels of agriculture. These data are physically published at the county, state, and national level on a 5-year cycle, detailing various material counts such as acreage, yields, and water usage, as well as socioeconomic estimates of farm costs, revenues, and hired ...


A Perplexing Process: Understanding How Agricultural Producers Process Best Management Practice Information, Audrey E. H. King, Lauri M. Baker Nov 2018

A Perplexing Process: Understanding How Agricultural Producers Process Best Management Practice Information, Audrey E. H. King, Lauri M. Baker

Journal of Applied Communications

Best management practices (BMPs) are suggested practices that help agricultural producers optimize production while reducing pollution, soil erosion, and other environmental impacts. Many audiences, including scientists and policy makers, have expressed disappointment at the current level of BMP use. Elaboration likelihood model (ELM) is used to understand how people process messages. ELM states that people can process messages either centrally or peripherally. This study sought to understand how producers processed information related to BMP adoption in grazing systems. Researchers conducted qualitative, in-depth interviews with 42 beef-cattle producers in Kansas and Oklahoma. It was found producers process information both centrally and ...

Haile, Kirby T. Nilsen, Sean Walkowiak, Yuefeng Ruan, Asheesh K. Singh, Fran R. Clarke, John M. Clarke, Curtis J. Pozniak

Agronomy Publications

Durum wheat was introduced in the southern prairies of western Canada in the late nineteenth century. Breeding efforts have mainly focused on improving quality traits to meet the pasta industry demands. For this study, 192 durum wheat lines were genotyped using the Illumina 90K Infinium iSelect assay, and resulted in a total of 14,324 polymorphic SNPs. Genetic diversity changed over time, declining during the first 20 years of breeding in Canada, then increased in the late 1980s and early 1990s. We scanned the genome for signatures of selection, using the total variance Fst-based outlier detection method (Lositan), the hierarchical ...

Perennial Biomass Crop Establishment, Community Characteristics, And Productivity In The Upper Us Midwest: Effects Of Cropping Systems Seed Mixtures And Biochar Applications, Catherine L. Bonin, Rivka B. Fidel, Chumki Banik, David A. Laird, Robert Mitchell, Emily A. Heaton

Agronomy Publications

Native perennial plants have potential as bioenergy feedstocks, but their use is currently limited by relatively long establishment times and low biomass yields. Some research suggests that incorporating plant species diversity and applying biochar as a soil amendment might alleviate these limitations by creating a more resilient crop and soil system. The objective of this research was to investigate how 1) seeded plant diversity and 2) biochar soil amendments interact to affect the establishment, yield, and plant species composition of biomass cropping systems during the first four years of growth on productive soils. We measured species emergence, cover, peak and ...

Identification Of Genes/Genomic Regions Controlling Resistance To Biotic And Abiotic Stresses In Synthetic Hexaploid Wheat, Madhav Bhatta

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Synthetic hexaploid wheat (SHW; 2n=6x=42, AABBDD, Triticum aestivumL.) is produced from an interspecific cross between durum wheat (2n=4x=28, AABB, T. turgidumL.) and goat grass (2n=2x=14, DD, AegilopstauschiiCoss.). It is reported to have a considerable amount of genetic diversity and is a potential source of novel alleles controlling abiotic and biotic stresses resistance and improving wheat quality. Therefore, the first study was to understand the genetic diversity and population structure of SHWs and compare the genetic diversity of SHWs with elite bread wheat (BW) cultivars. The result of this study identified a ...
