Environmental Impacts Of Stover Removal In The Corn Belt, Alicia English, Wallace E. Tyner, Juan Sesmero, Phillip Owens, David J. Muth Jr. Aug 2012

Environmental Impacts Of Stover Removal In The Corn Belt, Alicia English, Wallace E. Tyner, Juan Sesmero, Phillip Owens, David J. Muth Jr.

David J. Muth

When considering the market for biomass from corn stover resources erosion and soil quality issues are important to consider. Removal of stover can be beneficial in some areas, especially when coordinated with other conservation practices, such as vegetative barrier strips and cover crops. However, benefits are highly dependent on several factors, namely if farmers see costs and benefits associated with erosion and the tradeoffs with the removal of biomass. This paper uses results from an integrated RUSLE2/WEPS model to incorporate six different regime choices, covering management, harvest and conservation, into a simple profit maximization model to show these tradeoffs.

Transcendental Thermodynamics, Richard E. Morel, George Fleck Jun 2012

Transcendental Thermodynamics, Richard E. Morel, George Fleck

Kahn Institute Projects

Thermodynamics is often viewed as a narrow, introspective discipline, trapped by its origins in the 18th and 19th centuries. By dramatic contrast, we show that the Fourth Law of Thermodynamics provides explanations and interpretations of all natural events, extending across artificial boundaries of tradition- al academic disciplines. The Fourth Law of Thermodynamics states that far-from-equilibrium systems increase entropy at the maximum rate available to them. This broadly inclusive paradigm applies to systems from molecules, to organisms, to the biosphere. The Fourth Law is the Law of Evolution. All systems that communicate with their environment exhibit self-organization and self-optimization, enabling the …

It is an essential ingredient in food production, but poor management means bad news downstream. Understanding the way phosphorus behaves in the environment calls for soil and plant biology, and some new soil chemistry.


Engaging With The (Un)Familiar: Field Teaching In A Multi-Campus Teaching Environment, Nicholas Gill, Michael Adams, Christine Eriksen Jan 2012

Engaging With The (Un)Familiar: Field Teaching In A Multi-Campus Teaching Environment, Nicholas Gill, Michael Adams, Christine Eriksen

Field trips have long been central to geography, but have been subject to assessment of the role of the 'field' in teaching. At the same time, academics face barriers to running field trips. Distance education and enhanced educational access for non-metropolitan students represented such an obstacle at an Australian university. These obstacles were taken as an opportunity to draw on the regional nature of the students and staff to enhance teaching goals, run critically informed field trips by and manage academic workloads. We evaluate the field trips by conducting surveys and interviews with students and tutors, and as an example …


The Environmental And Cultural Effects On The Conquest Of Mexico, Tristan Siegel Jan 2012

The Environmental And Cultural Effects On The Conquest Of Mexico, Tristan Siegel

Senior Projects Spring 2012

In this work I examine the environment and cultural attitudes of Mesoamericans, specifically the Mexica (Atzec), and how these factors played a role in the Conquest of Mexico by Hernan Cortes. I begin by examining Mesoamerican agriculture, lithic technology, and metallurgy. I conclude by examining how these factors played out in the Conquest.
