Reduction Of Transportation Greenhouse Gas Emissions To Mitigate Climate Change Impacts, Mary Snow, Richard Snow May 2014

Reduction Of Transportation Greenhouse Gas Emissions To Mitigate Climate Change Impacts, Mary Snow, Richard Snow

Publications

Weather affects almost all modes of transportation in a modern society, and likewise, transportation has an enormous impact on the weather. Transportation greenhouse gas emissions (GHG) impact climate change, which impacts transportation in return. Reduction of transportation impacts on climate change can mitigate the reverse climate change impacts on transportation. This paper examines the relationship between transportation and climate change and establishes prospective solutions to reduce transportation greenhouse gas emission impacts on climate change and mitigate the reverse climate change impacts on transportation.


Economic And Environmental Comparison Of Different Ordering Policies For An Integrated Inventory Control And Supplier Selection Problem, Sepideh Almasi Monfared Jan 2014

Economic And Environmental Comparison Of Different Ordering Policies For An Integrated Inventory Control And Supplier Selection Problem, Sepideh Almasi Monfared

Masters Theses

"This study analyzes an integrated inventory control and supplier selection problem in stochastic demand environment under carbon emissions regulations. In particular, a continuous review inventory model with multiple suppliers is investigated under carbon taxing and carbon trading regulations. We analyze and compare the optimal supplier selection and order splitting decisions with single sourcing and two alternative delivery structures for multi-sourcing, namely, sequential ordering and sequential delivery. For each of the three ordering policies, a solution method is proposed and these policies are compared in terms of their economic as well as environmental performances. A numerical study is conducted to demonstrate …


An Experimental And Computational Evaluation Of The Importance Of Molecular Diffusion In Gas Gravity Currents, Jeremy Jac Herman Dec 2013

An Experimental And Computational Evaluation Of The Importance Of Molecular Diffusion In Gas Gravity Currents, Jeremy Jac Herman

Graduate Theses and Dissertations

The accidental release of hazardous, denser-than-air gases during their transport or manufacture is a vital area of study for process safety researchers. This project examines the importance of molecular diffusion on the developing concentration field of a gas gravity current released into a calm environment. Questions which arose from the unexpectedly severe explosion in 2005 at Buncefield, England were of particular interest. The accidental overfilling of a large tank with gasoline on a completely calm morning led to a massive open air explosion. Forensic evidence showed that at the time of ignition, a vapor cloud, most of which now appears …

Evaluation Of Broiler Litter Heat Production During Windrowing & Nitrogen Based Gas Emission Mitigation Using Biofilter, Min Lei Aug 2013

Evaluation Of Broiler Litter Heat Production During Windrowing & Nitrogen Based Gas Emission Mitigation Using Biofilter, Min Lei

Graduate Theses and Dissertations

Ammonia emission from animal feeding operations (AFOs) has negative effects on environment and animals' health. Thus measuring and mitigating ammonia emission from AFOs is important for environmental protection. In chapter I, different ammonia measurements were discussed and a mitigation technology- biofilter was represented.

In-house windrowing of built-up litter has been used by broiler producers to reduce pathogen loads and rejuvenate litter for the next flock. When litter is piled up for an extended period during downtime, heat generated by the litter pile can become a substantial heat source due to the metabolism of microorganisms. In chapter II, heat production rates …


Experiments To Measure The Effects Of Timber Harvesting Equipment On Surface Lithic Scatters, Douglas J. Baughman Jan 2013

Experiments To Measure The Effects Of Timber Harvesting Equipment On Surface Lithic Scatters, Douglas J. Baughman

All Master's Theses

The importance of cultural resource preservation cannot be overstated; however local economies are at least as important. Due to conservative archaeological site protection practices in Region 5 of the United States Forest Service, the economy of Northeastern California is being adversely affected. In an attempt to help the Forest Service make more informed management decisions and improve the Northeastern California economy, I undertook experiments on the effects of timber harvesting on lithic scatters on Modoc National Forest. The experiments involved placement of 225 glass tiles (proxy lithics) in each of three plots subject to vehicle traffic and log dragging by …


Factors For Improved Fish Passage Waterway Construction, David N. Sillars, Hamid Moradkhani, Nicholas Tymvios, Trevor D. Smith Jun 2011

Factors For Improved Fish Passage Waterway Construction, David N. Sillars, Hamid Moradkhani, Nicholas Tymvios, Trevor D. Smith

TREC Final Reports

Streambeds are important fish passageways in Oregon; they provide for the necessary habitats and spawning cycles of a healthy fish population. Oregon state law requires that hydraulic structures located in water properly provide fish passage. Increasingly stringent state and federal regulations apply to these fish passageways, and designers must become more cognizant of conditions over a range of flows to accommodate fish movement and avoid expensive structural failure of these passageways. Fish passage structures are built when roads cross streambeds and may include culverts, or bridges. When these structures are built, the streambeds are re-created using a technique called “roughened …


Energy Security: An Australian Nuclear Power Industry, Geoff I. Swan Jan 2009

Energy Security: An Australian Nuclear Power Industry, Geoff I. Swan

Australian Security and Intelligence Conference

Climate change and energy security are driving a worldwide renaissance in nuclear power. An Australian nuclear power industry has also been seriously investigated by the Australian government and its agencies. This paper provides a broad overview of the nuclear fuel cycle and the nuclear power industry. It identifies aspects that are sensitive to nuclear terrorism and nuclear weapons proliferation to help security professionals identify threats and prepare for a possible Australian nuclear power industry.


Nepa And The Dynamics Of Public Participation In The Environmental Review Process: An Analysis Of The Northmet (Polymet) Mining Project Near Hoyt Lakes Minnesota, Amber Neumann Jan 2009

Nepa And The Dynamics Of Public Participation In The Environmental Review Process: An Analysis Of The Northmet (Polymet) Mining Project Near Hoyt Lakes Minnesota, Amber Neumann

Political Science Theses and Capstones

Hypothesis: That comments collected from agency “experts” during the scoping phase of the National Environmental Policy Act (NEPA) process would be disproportionately represented as changes in subsequent drafts of NorthMet’s Environmental Impact Statement (EIS).

Methods: Tabular analysis of data collected from the Minnesota DNR publication of Response to the Public Scoping Projects PolyMet Mining Inc.; NorthMet Project. 2005

Results: There is an excellent cross section of comment sources represented in changes to subsequent drafts of NorthMet’s EIS. A lot of overlap exists between various types of participants and their concerns, resulting in many of the successful comments stemming from …

A Recommendation For An Enhanced Fujita Scale (Ef-Scale) Jun 2004

A Recommendation For An Enhanced Fujita Scale (Ef-Scale)

United States Department of Commerce: Staff Publications

Background

National Weather Service (NWS) personnel who are responsible for rating tornadoes have expressed frustrations in applying the Fujita Scale in a consistent and accurate manner. Weak links in a structural system or a slow-moving storm sometimes lead to an overrating of a tornado event. Several technical articles suggest that wind speeds associated with some descriptions of damage are too high. For example, a 260 mph wind speed is not required to completely destroy a well constructed house and blow away the debris. The damage occurs at significantly lower wind speeds. Minor et al. (1977) and Phan and Simiu (2003) …

A by-product of these centers is a strengthened core curriculum which brings the applied sciences into focus for all WKU students.


Plan Of Study For Cross Florida Barge Canal: Economic Analysis, United States. Army. Corps Of Engineers. Jacksonville District Mar 1983

Plan Of Study For Cross Florida Barge Canal: Economic Analysis, United States. Army. Corps Of Engineers. Jacksonville District

Correspondence and Textual Material

At the time of the previous study of transportation savings, commerce in coal primarily for electric power generation could not be ·projected with any degree of accuracy because most electric utilities had not developed firm plans for building new coal-fired plants· or for converting from petroleum products or natural gas to coal at existing plants. Today, with plants already constructed that will burn coal, there is a greater probability of defining coal needs. So there is a need to reevaluate potential coal traffic via the CFBC. Also there is a need to evaluate the other types of benefits mentioned under …
