Effects Of Preservation With Pre-Fermented Green Juice (Fgj) On Fermentation Quality And Energy And Nitrogen Utilization Of Round-Baled Alfalfa Silage By Dairy Cattle, Li-Man Cao, Yoshitaka Deguchi, M. Mizutani, M. Goto, Y. Yamamoto, S. Urakawa, Y. Yamada, M. Matsui, T. Masuko, Yasuhiro Kawamoto

IGC Proceedings (1993-2023)

This study was conducted to examine the effects of pre-fermented green juice (FGJ) of epiphytic lactic acid bacteria (LAB) on the fermentation quality and animal performance of round-baled alfalfa silage (Medicago stativa L.,cv. Dupuits). Ensiling treatments of wilting and FGJ additives (WFGJ) and direct-cut and FGJ additives (DFGJ) improved the fermentation quality of alfalfa silage more than that of wilting (W). Enhanced fermentation in the WFGJ and DFGJ silage was also associated with the increases of energy and nitrogen utilization of the silage by dry Holstein dairy cattle, as fed on diets formulated with alfalfa silage, oat …


Effect Of Application Of Farmyard Manure To Ley On Forage Yield And Quality Of Grass Silage, T. M. Pauly, L. Rodhe Dec 2021

Effect Of Application Of Farmyard Manure To Ley On Forage Yield And Quality Of Grass Silage, T. M. Pauly, L. Rodhe

IGC Proceedings (1993-2023)

A two-year field trial was performed on ley near Uppsala, Sweden, with the following treatments (3 plots/treatment): A, no manure or fertiliser; B, manure applied in Oct.; C, manure applied in Oct. followed by rolling plots in May; D, manure applied in May; E, mineral fertiliser only. Apart from cattle manure, plots allocated to treatments B, C and D received the same amount of mineral nutrients as treatment E. The objective of this experiment was to get an indication of how different times of manure application (before or after the growth period) affected forage yields and the quality of the …

The Effects Of Cellulase On Cell Wall Structure And The Rumen Digestion Of Alfalfa Silage, T. Ishida, A. Aisan, K. Tomiyama, T. Watanabe, H. Terui, E. No, K. Ataku

IGC Proceedings (1993-2023)

First- and second-cut alfalfa (Medicago sativa) was ensiled with no additive, microbial (Lactobacillus casei) inoculant, cellulase derived from Acremonium celluloytics Y-94, co-addition of inoculant and cellulase, and formic acid. The resultant silages were digested in the rumen of a dairy cow. The alfalfa and the silages were then examined with scanning electron microscope (SEM) and their chemical characteristics analyzed to evaluate the effects of cellulase on the quality of alfalfa silage and its cell wall structure.

The addition of cellulase lend to both a greater loss of parenchymal tissue and decrease in digestibility during rumen degradation …


Evidence For Quasi-Periodic Oscillations In The Recurrent Emission From Magnetars And Their Implications On The Neutron Star Properties And Equation Of State, Ahmed Monzer El Mezeini Dec 2021

Evidence For Quasi-Periodic Oscillations In The Recurrent Emission From Magnetars And Their Implications On The Neutron Star Properties And Equation Of State, Ahmed Monzer El Mezeini

Archived Theses and Dissertations

In this thesis, we present an analysis of highly magnetized neutron stars â magnetarsâ , in search for high frequency oscillations in the recurrent emission from the soft gamma repeater SGR 1806-20, and we discuss the physical interpretation of these oscillations and its implications on the neutron star properties and structure. We present evidence for Quasi-Periodic Oscillations (QPOs) in the recurrent outburst activity from the soft gamma repeater SGR 1806-20 using Rossi X-ray Timing Explorer (RXTE) observations. By searching a large sample of bursts for timing signals at the frequencies of the QPOs discovered in the 2004 December 27 giant …


Implications From Uranium-Series Disequilibria In A Bi-Lithologic Melt With Varying Lithospheric Caps, Juliet Messer Dec 2021

Implications From Uranium-Series Disequilibria In A Bi-Lithologic Melt With Varying Lithospheric Caps, Juliet Messer

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Both spreading rates and local magma supply to mid-ocean ridges affect crustal construction styles and ridge morphology, alternately leading to either asymmetrical (detachment faulting) or symmetrical faulting styles. Uranium-series isotopic disequilibria in mid-ocean ridge basalts (MORB) may provide insight into how melt supply variations relate to ridges’ accretion styles, a processes that are not well understood. I use Reactive Porous Flow (RPF) equilibrium and disequilibrium modeling to simulate U-series disequilibria at mid-ocean ridge (MOR) generated by melt supply variations at both asymmetrical and symmetrical ridge segments.

Guided by my modeling, I predict that enhanced melt contributions from enriched pyroxenitic mantle …

Soil Microbial Community Dynamics In Response To Prescribed Extreme Fires Following Juniperus Virginiana Invasion In The Loess Canyons Of Nebraska, Julie A. Fowler Dec 2021

Soil Microbial Community Dynamics In Response To Prescribed Extreme Fires Following Juniperus Virginiana Invasion In The Loess Canyons Of Nebraska, Julie A. Fowler

School of Natural Resources: Dissertations, Theses, and Student Research

In Nebraska and other regions of the Great Plains, the conifer Juniperus virginiana (eastern redcedar) is converting grasslands to dense woodlands. This is driven by the interacting drivers of fire suppression, altered grazing regimes, climate change and other anthropogenic factors, impacting the provisioning of ecosystem services. This vegetation state transition modifies water resource regulation and biogeochemical cycles leading to altered edaphic properties including soil microbial community composition. To restore these grasslands and control J. virginiana spread, prescribed extreme burns are implemented as a management tool through local prescribed burn associations. We hypothesized that the alternative state transition to dense J. …


Weak Cayley Table Groups Of Crystallographic Groups, Rebeca Ann Paulsen Dec 2021

Weak Cayley Table Groups Of Crystallographic Groups, Rebeca Ann Paulsen

Theses and Dissertations

Let G be a group. A weak Cayley table isomorphism $\phi$: G $\rightarrow$ G is a bijection satisfying two conditions: (i) $phi$ sends conjugacy classes to conjugacy classes; and (ii) $\phi$(g1)$\phi$(g2) is conjugate to $\phi$(g1g2) for all g1, g2 in G. The set of all such mappings forms a group W(G) under composition. We study W(G) for fifty-six of the two hundred nineteen three-dimensional crystallographic groups G as well as some other groups. These fifty-six groups are related to our previous work on wallpaper groups.

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

The Deepwater Horizon (DWH) oil spill occurred in a region of the Gulf of Mexico (GoM) supporting abundant, diverse and valuable communities of fishes and fishers. The economy of the northern GoM is inextricably tied to the natural resource bases of the region (tourism, fishing, oil and gas, etc.) and thus the coupling between the human and ecological systems is tight and subject both feed-back and, to some extent, feed-forward controls. Management actions taken during the 87-day DWH spill incident included the closure of over 280,000 km2 of productive fishing area (about 1/3 of USA federal waters in the …

Biostratigraphy Of Paleogene Diatom Assemblages In The Southern Ocean, Angela Kaup Dec 2021

Biostratigraphy Of Paleogene Diatom Assemblages In The Southern Ocean, Angela Kaup

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The record of siliceous microfossil sedimentation in the high latitude South Atlantic Ocean has great potential for dating seismic and stratigraphic units. Over the last several decades, scientists have documented diatom biostratigraphic record from sediment cores and drill cores in the Falkland Plateau and Maurice Ewing Bank region, as well as other areas of the Southern Ocean, and a robust chronostratigraphic framework is available for Neogene sequences. Given the complicated nature of ocean bathymetry, tectonic plate motion (vertical and lateral), and ocean current flow, the sedimentological evolution of this oceanic region is not well understood. Sampling sediment cores at high …


Computational Solutions To Exosomal Microrna Biomarker Detection In Pancreatic Cancer, Thuy T. An Dec 2021

Computational Solutions To Exosomal Microrna Biomarker Detection In Pancreatic Cancer, Thuy T. An

Department of Computer Science and Engineering: Dissertations, Theses, and Student Research

Pancreatic cancer is the fourth leading cause of cancer death in the United States and the 5-year survival rate is only 5% to 10%. There are only a few non-specific symptoms associated with the early-stage cancer, therefore most patients are diagnosed in a late stage. Due to the lack of effective treatments and the fact that the early stage has a 39% 5-year survival rate, the biggest hope to control this disease is early detection. Therefore, discovery of effective and reliable non-invasive biomarkers for early detection of pancreatic cancer has been a major topic. Very recently, exosomal microRNAs have become …


Anthropogenic Impacts To Essential Habitats In The Gulf Of Maine: A Case Study Of The American Lobster, Homarus Americanus, And Its Fishery, Andrew Goode Dec 2021

Anthropogenic Impacts To Essential Habitats In The Gulf Of Maine: A Case Study Of The American Lobster, Homarus Americanus, And Its Fishery, Andrew Goode

Electronic Theses and Dissertations

The Gulf of Maine has been fundamentally altered by anthropogenic forcings for decades and offers an ideal study system to monitor response to change. Through complex interactions between ocean warming, altered demographic bottlenecks, and reduced top-down controls, the American lobster (Homarus americanus Milne Edwards) capitalized on favorable conditions and proliferated within the Gulf of Maine. These changes catalyzed the expansion of the lobster fishery, elevated its status as North America’s most valuable marine resource, and shifted coastal communities towards a virtual lobster monoculture. The same processes that facilitated lobster to capitalize on favorable conditions may come with unintended consequences …


Fabrication Of Advanced Materials For Chromatography, Sample Preparation, And Separations, And Accompanying Material Characterization, Dhananjay I. Patel Dec 2021

Fabrication Of Advanced Materials For Chromatography, Sample Preparation, And Separations, And Accompanying Material Characterization, Dhananjay I. Patel

Theses and Dissertations

My dissertation primarily focuses on the fabrication of materials for solid phase microextraction (SPME) and separation devices. In my first project, I used direct current magnetron sputtering (DCMS) to prepare sputtered silicon coatings on fused silica fibers. These fibers were then subjected to the chemical vapor deposition of 6-phenyhexylsilane (6-PH) as a stationary phase. Six different types of fibers were made using two different throw distances (4 cm and 20 cm) and three different silicon thicknesses (0.5, 1.8, and 2.8 µm). These coatings were characterized by time-of-flight secondary ion mass spectrometry (ToF-SIMS), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), …


The Effect Of Cellulase On Cell Wall Structure And The Rumen Digestion Of Timothy Silage, A. Aniwaru, T. Ishida, T. Watanabe, K. Tomiyama, H. Terui, K. Ataku, L. E. Chase Dec 2021

The Effect Of Cellulase On Cell Wall Structure And The Rumen Digestion Of Timothy Silage, A. Aniwaru, T. Ishida, T. Watanabe, K. Tomiyama, H. Terui, K. Ataku, L. E. Chase

IGC Proceedings (1993-2023)

The objective of this study was to determine the effect of additives on the structure changes of related tissues during the ensiling process and the rumen digestion of timothy. In the first cut-timothy, the addition of LC+AC improved the fermentation qualities of the silage. Addition of cellulase resulted in significant decreases in NDF, ADF, cellulose, and hemicellulose content. SEM examination of the samples suggests that the degradation of parenchymal tissues was enhanced by the cellulase, but no significant differences were observed among the additives in the rumen digestion. The NDF and cellulose digestibility of the AC- and LC+AC-treated silages were …

Quality Of Ammoniated Brachiaria Decumbens Hay, L. O. Fernandes, Ricardo A. Reis, L. R. A. Rodrigues

IGC Proceedings (1993-2023)

The experiment was conducted at UNESP-Jaboticabal to evaluate the quality of Brachiaria decumbens hays harvested after seed ripening. The hays were submitted to the following treatments: control, anhydrous ammonia (3.0% NH3 in the DM), and urea (5.0% in the DM). The chemical composition, digestibility and the performance of steers were evaluated using a complete randomized block design with three treatments and six replications. The ammoniation either with NH3 or urea increased (P< 0.05) the CP content, and the IVDMD. The NH3 treatment reduced (P < 0.05) the contents of NDF and ADF, and the urea application reduced (P < 0.05) the contents of hemicellulose and lignin. The ammoniation did not affect (P > 0.05) the neutral detergent insoluble nitrogen, and acid detergent insoluble nitrogen values. Steers receiving Brachiaria hay plus soybean meal (1.08 kg DM.day), hay …
