Aeschynomene And Carpon Desmodium: Legumes For Bahiagrass Pasture In Florida, Lynn E. Sollenberger, R. S. Kalmbacher Jun 2023

Aeschynomene And Carpon Desmodium: Legumes For Bahiagrass Pasture In Florida, Lynn E. Sollenberger, R. S. Kalmbacher

IGC Proceedings (1977-2023)

Soils and climate are very diverse across Florida, and no single legume has state-wide adaptation. However, aeschynomene (Aeschynomene americana), an annual, and carpon desmodium (Desmodium heterocarpon) cv. Florida, a perennial, are the most commonly used legumes for grazing on the central and southern peninsula, which produces 65% of Florida's beef calves. Both grow well with bahiagrass (Paspalum notatum), which is the main pasture grass, with ~1M ha state-wide. Circa 65K ha of bahiagrass contain at least limited quantities of aeschynomene and 14K ha contain carpon desmodium.


Rhizoma Peanut: More Than A ‘Lucerne’ For Subtropical Usa, M. J. Williams, K. H. Quesenberry, G. M. Prine, C. B. Olson Jun 2023

Rhizoma Peanut: More Than A ‘Lucerne’ For Subtropical Usa, M. J. Williams, K. H. Quesenberry, G. M. Prine, C. B. Olson

IGC Proceedings (1977-2023)

Rhizoma peanut (Arachis glabrata) was introduced to Florida from South America in the 1930s. Selections 'Arb' (PI 118457) and 'Arblick' (PI 262839) were released in the 1960s, but their use was very limited due to slow establishment and low productivity. The University of Florida released 'Florigraze' (PI 421707) in 1978 and 'Arbrook' (PI 262817) in 1986. These cultivars produced much higher dry matter yields. Thereafter, rhizoma peanut began to gain commercial acceptance. These cultivars are used throughout the Gulf Coast region of the USA for commercial hay production, pasture, creep grazing, silage, balage, and living mulch (French et …


Species And Chlorine Fertilisation Affect Dietary Cation-Anion Difference Of Cool-Season Grasses, Gilles Bélanger, Sophie Pelletier, H. Brassard, Gaëtan F. Tremblay, Philippe Seguin, R. Drapeau, A. Brégard, Réal Michaud, Guy Allard Jun 2023

Species And Chlorine Fertilisation Affect Dietary Cation-Anion Difference Of Cool-Season Grasses, Gilles Bélanger, Sophie Pelletier, H. Brassard, Gaëtan F. Tremblay, Philippe Seguin, R. Drapeau, A. Brégard, Réal Michaud, Guy Allard

IGC Proceedings (1977-2023)

The Dietary Cation-Anion Difference [DCAD = (Na + K) - (Cl + S); Ender et al., 1971] is used in balancing rations for dry dairy cows. Low DCAD diets induce a mild, compensated metabolic acidosis that stimulates bone resorption, improves Ca homeostasis, and prevents milk fever. Dry cow rations contain a high proportion of forage and, therefore, forages fed two to four weeks prepartum should have a low or negative DCAD value. Our objectives were to evaluate the DCAD of five cool-season grass species grown in eastern Canada and to determine the effect of Cl fertilisation on the DCAD …


Forage Quality Of Cool Season Pasture Species Under Two Rotational Grazing Height Regimes, H. D. Karsten, M. Carlassare Jun 2023

Forage Quality Of Cool Season Pasture Species Under Two Rotational Grazing Height Regimes, H. D. Karsten, M. Carlassare

IGC Proceedings (1977-2023)

To optimize animal and pasture performance in management intensive grazing systems, pasture production and quality often must be compromised. Rotationally-stocking pastures at slightly taller grazing heights can increase pasture productivity, but lower forage quality may limit animal performance. Our objective was to compare the forage quality of common cool season pasture species in the Northeastern U.S., under two rotational grazing regimes defined by slightly different grass heights.

There is a need to assess challenges in smart sustainable cities based on IoT. This paper is …


Consistency Of Effective Field Theory Analyses Of The Boss Power Spectrum, T. Simon, P. Zhang, V. Poulin, Tristan L. Smith Jun 2023

Consistency Of Effective Field Theory Analyses Of The Boss Power Spectrum, T. Simon, P. Zhang, V. Poulin, Tristan L. Smith

Physics & Astronomy Faculty Works

We assess the robustness of Λ cold dark matter (Λ CDM) results from the full-shape analysis of BOSS power spectrum using the one-loop prediction of the effective field theory of large-scale structure (EFTofLSS). In former EFT analyses, the two public likelihoods pybird and class-pt lead to results in agreement only at the 1σ level, which may appear unsatisfactory given that they are derived from the same BOSS dataset and the same theory model. To identify the origin of the difference, we perform a thorough comparison of the various analyses choices made between the two pipelines. We find that most …

We investigate the star formation main sequence (MS; SFR-M ∗) down to 108-9 M o˙ using a sample of 34,061 newly discovered ultrafaint (27 mag ≲ i ≲ 30 mag) galaxies at 1 < z < 3 detected in the GOODS-N field. Virtually none of these galaxies are contained in previous public catalogs, effectively doubling the number of known sources in the field. The sample was constructed by stacking the optical broadband observations taken by the HST/GOODS-CANDELS surveys, as well as the 25 ultradeep medium-band images gathered by the GTC/SHARDS project. Our sources are faint (average observed magnitudes 〈i〉 ∼28.2 and 〈H〉 ∼27.9 mag), blue (UV slope 〈β〉 ∼-1.9), star-forming (rest-frame colors 〈U - V〉 ∼0.10 and 〈V - J〉 ∼0.17 mag) galaxies. These observational characteristics are identified with young (mass-weighted age 〈t M-w 〉 ∼0.014 Gyr) stellar populations subject to low attenuations (〈A(V)〉 ∼0.30 mag). Our sample allows us to probe the MS down to 108.0 M o˙ at z = 1 and 108.5 M o˙ at z = 3, around 0.6 dex deeper than previous analyses. In the low-mass galaxy regime, we find an average value for the slope of 0.97 at 1 < z < 2 and 1.12 at 2 < z < 3. Nearly 60% of our sample presents stellar masses in the range 106-8 M o˙ at 1 < z


Limits On Leptonic Tev Emission From The Cygnus Cocoon With Swift-Xrt, David Guevel, Andrew Beardmore, Kim L. Page, Amy Lien, Ke Fang, Luigi Tibaldo, Sabrina Casanova, Petra Huentemeyer Jun 2023

Limits On Leptonic Tev Emission From The Cygnus Cocoon With Swift-Xrt, David Guevel, Andrew Beardmore, Kim L. Page, Amy Lien, Ke Fang, Luigi Tibaldo, Sabrina Casanova, Petra Huentemeyer

Michigan Tech Publications, Part 1

3-ray observations of the Cygnus Cocoon, an extended source surrounding the Cygnus X star-forming region, suggest the presence of a cosmic-ray accelerator reaching energies up to a few PeV. The very-high-energy (VHE, 0.1-100 TeV) 3-ray emission may be explained by the interaction of cosmic-ray hadrons with matter inside the Cocoon, but an origin of inverse Compton radiation by relativistic electrons cannot be ruled out. Inverse Compton 3-rays at VHE are accompanied by synchrotron radiation peaked in X-rays. Hence, X-ray observations may probe the electron population and magnetic field of the source. We observed 11 fields in or near the Cygnus …

The Applicability Of The Postmortem Submersion Interval Estimation Formula For Human Remains Found In Subtropical Aquatic Environments, Kara L. Dicomo Jun 2023

The Applicability Of The Postmortem Submersion Interval Estimation Formula For Human Remains Found In Subtropical Aquatic Environments, Kara L. Dicomo

USF Tampa Graduate Theses and Dissertations

Within the past decade, several attempts have been made to standardize a method for estimating postmortem submersion intervals (PMSI); however, the majority of these studies have focused on data from a temperate climate which cannot be taken as representative of large portions of the globe. Thus, there are large portions of the earth in which the methodology from these studies may not be able to accurately estimate PMSI which has the potential to leave investigators in these other climatic zones at a disadvantage. This presentation presents a case study into the applicability of two Total Body Scoring Systems (TADS) utilized …


Supramolecular Architectures Generated By Self-Assembly Of Guanosine And Isoguanosine Derivatives, Mengjia Liu Jun 2023

Supramolecular Architectures Generated By Self-Assembly Of Guanosine And Isoguanosine Derivatives, Mengjia Liu

USF Tampa Graduate Theses and Dissertations

This dissertation is primarily divided into three parts: 1) Anion, solvent-mediated, tunable self-assemblies of isoguanosine (isoG). 2) Post-assembly modification of the non-covalent isoG-pentaplex for Cesium extraction. 3) Supramolecular asymmetric amine catalysis.

The structural conformational design of the isoG decamer was employed for systematic investigations involving various substituted groups at the C8 position of purine and ribose. A series of isoG analogs with C8-phenyl substitutions were synthesized and utilized for Cesium coordination. The proximity between purine and ribose structures limited pentaplex formation for C8-phenyl substituted isoG derivatives. Based on this observation, a deoxy isoG derivative with a modified ribose was employed …


Atomistic Assessment Of Drug-Phospholipid Interactions Consequent To Cancer Treatment: A Study Of Anthracycline Cardiotoxicity, Yara Elsayed Ahmed Jun 2023

Atomistic Assessment Of Drug-Phospholipid Interactions Consequent To Cancer Treatment: A Study Of Anthracycline Cardiotoxicity, Yara Elsayed Ahmed

Theses and Dissertations

Despite being one of the most effective chemotherapeutic agents developed to date, Anthracyclines are notorious for their cardiotoxicity. Their clinical use is frequently limited both in dosage and in prescription due to the severe cardiac damage they cause. The mechanism of anthracycline-induced cardiotoxicity is not yet fully understood. However, it is hypothesized that interactions with the myocardial membrane play an important role in imparting cardiotoxicity. In this study, we use molecular dynamics simulations and density functional theory calculations to study the anthracycline drug molecules and the interactions that they have with the myocardial membrane. We construct a myocardial membrane model …

Lagrangian Displacement Field Estimators In Cosmology, Atsuhisa Ota, Hee Jong Seo, Shun Saito, Florian Beutler

Physics Faculty Research & Creative Works

The late-time nonlinear Lagrangian displacement field is highly correlated with the initial field, so reconstructing it could enable us to extract primordial cosmological information. Our previous work [A. Ota et al., Phys. Rev. D 104, 123508 (2021)PRVDAQ2470-001010.1103/PhysRevD.104.123508] carefully studied the displacement field reconstructed from the late-time density field using the iterative method proposed by Schmittfull et al. [Phys. Rev. D 96, 023505 (2017)PRVDAQ2470-001010.1103/PhysRevD.96.023505] and found that it does not fully converge to the true, underlying displacement field (e.g., ∼8% offset at k∼0.2 h Mpc-1 at z=0.6). We also constructed the Lagrangian perturbation theory model for the reconstructed field, but the …


Anderson Localization Of Electromagnetic Waves In Three Dimensions, Alexey Yamilov, Sergey E. Skipetrov, Tyler W. Hughes, Momchil Minkov, Zongfu Yu, Hui Cao Jun 2023

Anderson Localization Of Electromagnetic Waves In Three Dimensions, Alexey Yamilov, Sergey E. Skipetrov, Tyler W. Hughes, Momchil Minkov, Zongfu Yu, Hui Cao

Physics Faculty Research & Creative Works

Anderson localization is a halt of diffusive wave propagation in disordered systems. Despite extensive studies over the past 40 years, Anderson localization of light in three dimensions has remained elusive, leading to the question of its very existence. Recent advances have enabled finite-difference time-domain calculations to be sped up by orders of magnitude, allowing us to conduct brute-force numerical simulations of light transport in fully disordered three-dimensional systems with unprecedented dimension and refractive index difference. We show numerically three-dimensional localization of vector electromagnetic waves in random aggregates of overlapping metallic spheres, in sharp contrast to the absence of localization for …

Blatter radical derivatives are very attractive due to their potential applications, ranging from batteries to quantum technologies. In this work, we focus on the latest insights regarding the fundamental mechanisms of radical thin film (long-term) degradation, by comparing two Blatter radical derivatives. We find that the interaction with different contaminants (such as atomic H, Ar, N, and O and molecular H2, N2, O2, H2O, and NH2) affects the chemical and magnetic properties of the thin films upon air exposure. Also, the radical-specific site, where the contaminant interaction takes place, plays …
