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 ...


Untangling The Economic And Social Impediments To Producer Adoption Of Organic Wheat, Donya L. Ralph-Quarnstrom May 2019

Untangling The Economic And Social Impediments To Producer Adoption Of Organic Wheat, Donya L. Ralph-Quarnstrom

All Graduate Theses and Dissertations

Consumer demand for organic products has shown double-digit growth in recent years encouraging the development of a wider range of goods (Greene, 2017). Americans with an annual household income under $30,000 actively purchase organic foods at nearly the same rate as households with over $75,000 in annual incomes, 42% versus 49% (Greene et al., 2017). Previous research observed the adoption of organic farming practices on a combination of different grains, fruits and vegetables, meat, and dairy products from across the globe. However, this is the first study to examine the adoption of organic wheat in the Western U ...


Exterranean [Table Of Contents], Phillip John Usher Mar 2019

Exterranean [Table Of Contents], Phillip John Usher

Literature

“For anyone who might be suffering from Anthropocene fatigue, this is a book to jolt you from your slumbers. What happens to the globe when we shift attention from the outward projection of emissions to extraction ? The Earth we thought we knew, and were already mourning, takes on a stunning new critical light.”—Claire Colebrook, Pennsylvania State University

Exterranean concerns the extraction of stuff from the Earth, a process in which matter goes from being sub- to exterranean. By bringing a rich archive of nonmodern texts and images from across Europe, into conversation with the contemporary work of Bruno Latour ...


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 Mar 2019

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 ...

Investigations Of The Potential For Irrigated Agriculture On The Bonaparte Plains: Bore Completion Report, 2nd Edition, D L. Bennett Feb 2019

Investigations Of The Potential For Irrigated Agriculture On The Bonaparte Plains: Bore Completion Report, 2nd Edition, D L. Bennett

Resource management technical reports

Drilling programs were undertaken in 2013 and 2016 by the former Department of Agriculture and Food, Western Australia and in 2017 by DPIRD, at 10 sites in the Bonaparte Plains area, north of Kununurra in the East Kimberley region of Western Australia (WA).

These drilling programs were a component of resource availability and risk investigations conducted to determine the potential for developing irrigated agriculture on 30 000 hectares of Cockatoo Sands — free-draining loamy soils that have the potential to support crops in the wet and dry seasons. There was limited hydrogeological information available at a suitable scale for the area ...


Sharing The Gift Of Water: A Hoosier-Haitian Partnership, Lauren Ward Jan 2019

Sharing The Gift Of Water: A Hoosier-Haitian Partnership, Lauren Ward

Purdue Journal of Service-Learning and International Engagement

Engagement Methods for International Food Security (YDAE 49100) provided an opportunity for enrolled students to travel abroad to Cap-Haitïen, Haiti. As both a course in agriculture and a service-learning study abroad, the overarching goal was to inspire, engage, and teach Purdue and Haitian students through service learning in agriculture. This was done by developing a project with teammates during the fall semester that was then presented to students in Haiti during the International Agri-Symposium at Université Antenor Firmin over winter break.

An Online Tool For Estimating Evapotranspiration And Irrigation Requirements Of Crops In South Carolina, Jose O. Payero Jan 2019

An Online Tool For Estimating Evapotranspiration And Irrigation Requirements Of Crops In South Carolina, Jose O. Payero

Journal of South Carolina Water Resources

In recent years, there has been an increased interest in South Carolina regarding the amount of water used by different consumers, especially agricultural producers. This interest has sparked conversations among different stakeholders, including the media, policy makers, producers, scientists, and the general public, regarding the current state and future of water resources in the state. Central to these discussions, from the agricultural sector perspective, is the question of how much water producers really need to grow crops. The objective of this study was, therefore, to develop an online tool to use local South Carolina historic weather data to estimate daily ...

Development Of Time-Weighted Average Sampling Of Odorous Volatile Organic Compounds In Air With Solid-Phase Microextraction Fiber Housed Inside A Gc Glass Liner: Proof Of Concept, Madina Tursumbayeva, Jacek A. Koziel, Devin L. Maurer, Bulat Kenessov, Somchai Rice Jan 2019

Development Of Time-Weighted Average Sampling Of Odorous Volatile Organic Compounds In Air With Solid-Phase Microextraction Fiber Housed Inside A Gc Glass Liner: Proof Of Concept, Madina Tursumbayeva, Jacek A. Koziel, Devin L. Maurer, Bulat Kenessov, Somchai Rice

Agricultural and Biosystems Engineering Publications

Finding farm-proven, robust sampling technologies for measurement of odorous volatile organic compounds (VOCs) and evaluating the mitigation of nuisance emissions continues to be a challenge. The objective of this research was to develop a new method for quantification of odorous VOCs in air using time-weighted average (TWA) sampling. The main goal was to transform a fragile lab-based technology (i.e., solid-phase microextraction, SPME) into a rugged sampler that can be deployed for longer periods in remote locations. The developed method addresses the need to improve conventional TWA SPME that suffers from the influence of the metallic SPME needle on the ...

Grazing Myths That Reduce Profitability, Greg S. Halich Jan 2019

Grazing Myths That Reduce Profitability, Greg S. Halich

Forage Symposium at the Kentucky Cattlemen’s Convention

Many cattle farms have moved to rotational grazing in the past decade, and there are significant benefits associated with this grazing technique. However, one thing that I have noticed is that costs are not always accounted for when it comes to recommended rotational grazing practices. If you ignore costs, partially or fully, you will invariably do too much of whatever you are considering. In this light, I will highlight four grazing recommendations (myths) that many folks are often taking to extremes related to rotational grazing, and one additional myth (generic to grazing style) that is reducing the overall profitability of ...

Economics Of Grazing Cover Crops, Ed Ballard

Forage Symposium at the Kentucky Cattlemen’s Convention

Feed costs represent the major cost in most livestock production systems. A completed analysis of 225 Standardized Performance Analysis (SPA) Beef Cow Records on herds in Illinois and Iowa showed that feed cost was the overriding factor determining profitability, explaining over 57 percent of the herd-to-herd variation.

Profitability At Eldon Farms: Guiding Principles, John Genho

Forage Symposium at the Kentucky Cattlemen’s Convention

Eldon Farms is a 7,000-acre farm in the Northern Piedmont of Virginia. Over the past 15 years, we have adopted a grazing program based on three principles. While the specifics of each operation are different, I believe these principles can be applied across a host of situations.

1912 - The Missions Of California And The Old Southwest, Jesse S. Hildrup Jan 2019

1912 - The Missions Of California And The Old Southwest, Jesse S. Hildrup

Miscellaneous Documents and Reports

A publication exhorting the glory of the California and Old Southwest missions, the golden climate and the efforts by the padres to save the Indian from his primitive life and ultimately prepare them for the civilization which came later under American sovereignty. The author viewed the region as the "chosen land, so wonderfully endowed by Nature, made possible the spiritual and civilizing purposes of the Church by the very configuration of its surface, the fertility of its soil, its temperate and subtropical climates, and its abundant water, which were stored in natural reservoirs and available for lowland cultivation by the ...
