Update On Technologies For Producing And Feeding Silage, P. D. Forristal, P. O'Keily

IGC Proceedings (1997-2023)

Key Points

1. Mechanisation and engineering inputs are key factors which contribute to silage costs.
2. Sensing technologies will improve management precision in many areas of ensilage.
3. While current harvesting machines have high output capacity reflecting mature design, there is a need to revisit the area of energy efficiency.
4. Baled silage technology, particularly in the areas of covering film and wrapping technology, needs further research.
5. Feeding systems are well researched but there is a need for systems research to underpin farmers’ decisions concerning housing design and feeding system.

Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski

Theses and Dissertations (Comprehensive)

The vast majority of the research into the performance of stormwater management ponds (SWMPs) has been performed in warm regions or during the warmer seasons in temperate regions. It is presumed that SWMPs are inactive in the winter as any potential stormwater is trapped in snow and ice. The main goal of this thesis was to test this presumption and to study the dynamics and performance of three SWMPs during the winter. Remote water level loggers were installed into the three SWMPs and daily grab samples from the influents and effluents were taken and analyzed for total phosphorus (TP), chloride, …

Subsurface Analytics: Contribution Of Artificial Intelligence And Machine Learning To Reservoir Engineering, Reservoir Modeling, And Reservoir Management, Shahab D. Mohaghegh

Faculty & Staff Scholarship

Subsurface Analytics is a new technology that changes the way reservoir simulation and modeling is performed. Instead of starting with the construction of mathematical equations to model the physics of the fluid flow through porous media and then modification of the geological models in order to achieve history match, Subsurface Analytics that is a completely AI-based reservoir simulation and modeling technology takes a completely different approach. In AI-based reservoir modeling, field measurements form the foundation of the reservoir model. Using data-driven, pattern recognition technologies; the physics of the fluid flow through porous media is modeled through discovering the best, most …

Lnfluence Of Persulfate On Solidification/Stabilization Characteristics Of Iss Treatment, Jeffrey M. Hudson

Masters Theses

Two environmental remediation technologies that lend themselves well to being combined in a single application are In Situ Chemical Oxidation (ISCO) using activated persulfate (PS), and In Situ Stabilization (ISS). Persulfate can be activated by increasing the pH to 10.5 and/or increasing temperatures to 30ºC. Many common ISS amendments increase temperature to 30°C and/or pH to 10.5 when in contact with soil water. Laboratory experiments were conducted with various soils to determine the ability of eight ISS amendments to activate persulfate. All eight ISS amendments activated persulfate. This work also showed that the relative contribution of heat vs. alkaline activation …

The Quasi-Static Deformation, Failure, And Fracture Behavior Of Titanium Alloy Gusset Plates Containing Bolt Holes, Therese Hurtuk, Craig Menzemer, Anil Patnaik, Tirumalai Srivatsan, Kannan Manigandan, T. Quick

Craig Menzemer

In this article, the influence of bolt holes, specifically their number and layout on strength, deformation, and final fracture behavior of titanium alloy gusset plates under the influence of an external load is presented and discussed. Several plates having differences in both the number and layout of the bolt holes were precision machined and then deformed under quasi-static loading. The specific influence of number of bolt holes and their layout on maximum load-carrying capability and even fracture load was determined. The conjoint influence of bolt number, bolt layout pattern, nature of loading, contribution from local stress concentration, and intrinsic microstructural …

Stratigraphic Framework And Landsystem Correlation For Deposits Of The Saginaw Lobe, Michigan, Usa, Ivan R. Guzman

Masters Theses

Since the time of the Last Glacial Maximum (LGM) the south-central portion of the Lower Michigan Peninsula has been subject to several glacial advances and retreats by the Saginaw lobe. As part of the U.S Geological Survey Great Lakes Geological Mapping Coalition projects, several rotosonic borings were drilled between 2006 and 2013 in Barry, Kalamazoo and Calhoun Counties. Gamma ray logs and textural analyses were completed for each core. Five of these borings were selected according to their diamicton (till) content and correlated using water well logs and surficial geology maps. Glacial deposits such as diamicton serve as evidence of …

Remote Analysis Of Grain Size Characteristic In Submarine Pyroclastic Deposits From Kolumbo Volcano, Greece, Clara Smart, D. P. Whitesell, Christopher N. Roman, Steven Carey

Graduate School of Oceanography Faculty Publications

Grain size characteristics of pyroclastic deposits provide valuable information about source eruption energetics and depositional processes. Maximum size and sorting are often used to discriminate between fallout and sediment gravity flow processes during explosive eruptions. In the submarine environment the collection of such data in thick pyroclastic sequences is extremely challenging and potentially time consuming. A method has been developed to extract grain size information from stereo images collected by a remotely operated vehicle (ROV). In the summer of 2010 the ROV Hercules collected a suite of stereo images from a thick pumice sequence in the caldera walls of Kolumbo …

Records Of Natural Fires And The Sorption Of Polycyclic Aromatic Hydrocarbons (Pahs) By Black Carbon And Carbon Chars In Sediments From Oriole Lake (Sequoia National Park), Kevyn Bollinger

Senior Honors Projects

This project investigates the interaction between Black Carbon and Polycyclic Aromatic Hydrocarbons (PAHs) in lake sediments from Oriole Lake in Sequoia National Park California. The interaction between Black Carbon and PAHs is of interest because little is known with respect to the availability and the time scale within which black carbon adsorbs PAHs in a natural system. Black Carbon and PAHs both will eventually be degraded in the environment but the relevant timescales of sorption and degradation are unknown. Field work for this project was conducted July 16-21, 2007 at Oriole Lake in Sequoia National Park California. Sequoia National Park …

Polarographic Determination Of Germanium, Calvin Leo Stevenson

Bachelors Theses and Reports, 1928 - 1970

In the past germanium has been determined by either wet methods or by the spectograph; the spectograph being used for the determination of very small amounts of ger­manium and wet methods used when more than one hundredth of one percent germanium is present. Both of these analyti­cal schemes have weaknesses.

A Study Of The Effects Of The Chloride Ion On The Lead-Silver Anodes And On The Lead Tenor Of The Zinc Deposit In Zinc Electrolysis, William A. Mitchell

Bachelors Theses and Reports, 1928 - 1970

The electrolyte used in the commercial production of electrolytic zinc from zinc sulphate solutions contains small amounts of impurities each of which has its own effects upon the process. Impurities such as antimony, cobalt, nickel, and iron tend to lower the current efficiency while other impurities such as chlorine, fluorine, and nitrates tend to increase the corrosion of the lead anodes and thereby increase the lead tenor of the zinc deposit.
