Screening Fresh Forages For Protein Degradation And Nutritive Value, Garry C. Waghorn, J. L. Burke

IGC Proceedings (1977-2023)

A method has been developed to prepare fresh forages for in sacco and in vitro incubation by freezing and mincing to achieve a particle size distribution of dry matter (DM) similar to in vivo conditions. The method is described and data presented to indicate losses of nitrogen (N) during in sacco digestion and net yield of ammonia from proteolysis in vitro for 22 fresh and conserved forages. Grasses, legumes and herbs were evaluated, with fractional degradation rates of forages ranging from 0.07h^-1 with tall fescue (Festuca arundinacea) to 0.24 h^-1 with chicory (Cichorium intybus). …

Study Of Safety And Efficacy Of Novel Sirolimus-Eluting Stent Incorporating Properties Of Drug Coating Balloon Among Real World Patients Focusing Among Younger Population ( Under 35 Years), Santosh Kumar Sinha, Umeshwar Pandey, Mahmodullah Razi, Awadesh K. Sharma, Puneet Aggarwal, Mohit Sachan, Praveen Shukla, Ramesh Thakur

Journal of the Saudi Heart Association

Objective- Aim of study was to evaluate safety and efficacy of abluminal Mitigator DES+ Sirolimus Eluting Stent (Envision Scientific, Surat, India) incorporating novel technology of fusion coating of bioresorbable polymer on both abluminal surface of stent and exposed parts of balloon among real world patients specially focusing younger patients ( < 35 years). Method- 1293 patients received Mitigator DES+ at LPS Institute of Cardiology, Kanpur, India. Primary outcome was target lesion failure (TLF)- composite of cardiovascular death, target vessel myocardial infarction (TVMI), and target lesion revascularization (TLR) and secondary end points including peri-procedural device failure (failure of stent delivery, change of stent, stent fracture), target vessel failure (TVF), and patient oriented composite end point (POCE)- composite of all deaths, MI, and revascularization and stent thrombosis (ST) at 1-year follow-up. Result- Younger population comprised of 374(29%) patients. Various indications of interventions were STEMI (n=614, 47.4%), NSTEMI (n=416, 32.2%), UA (n=161, 12.5%), and CCS (n=102, 7.9%). TLF at 1 year in overall population was 3.5% which was driven by TVMI and TLR in 1.3% and 1.1% patients respectively. POCE was observed in 9.5% mainly contributed by any revascularization (3.9%). Failure of stent delivery (1.1%) and edge dissection (0.5%) caused stent failure (2.2%). Definite and probable ST was observed in 1% and 0.8% patients respectively. Young patients showed insignificantly lower TLF, TVF, ST and POCE and significantly lower device failure (1.3% vs. 2.6%, p=0.04) when compared to patients >35 years. Conclusion- Mitigator DES+™ is safe among real world patients especially young population.

The Algorithmic Divide And Equality In The Age Of Artificial Intelligence, Peter K. Yu

Florida Law Review

In the age of artificial intelligence, highly sophisticated algorithms have been deployed to provide analysis, detect patterns, optimize solutions, accelerate operations, facilitate self-learning, minimize human errors and biases, and foster improvements in technological products and services. Notwithstanding these tremendous benefits, algorithms and intelligent machines do not provide equal benefits to all. Just as the “digital divide” has separated those with access to the Internet, information technology, and digital content from those without, an emerging and ever-widening “algorithmic divide” now threatens to take away the many political, social, economic, cultural, educational, and career opportunities provided by machine learning and artificial intelligence. …

Channelling Bamberger: An Unorthodox Appreciation Of Jeanne Bamberger's Work On Musical Development And Musical Understanding, Craig Graci

Visions of Research in Music Education

This article serves as a tribute to Bamberger as a notable researcher and teacher. The author articulates “working principles” that characterize Bamberger’s work and draws comparisons between two programs, Impromptu and Music Exploration Machine (MxM). From the perspective of music cognition, the most significant elements of this paper concern explicitly representing grouping structure and reductional structure of melodies within a computational formalism. From a developmental perspective, the most salient element is the identification and discussion of working principles associated with Bamberger’s compelling and challenging approach to research on musical development.

Alternative Representations For Music Composition, Kimberly Lansinger Ankney

Visions of Research in Music Education

Music teachers use standard notation and alternative representations of music in software programs to engage children in composition. However, there are benefits and limitations to these representations. This paper examines the relationship between children’s internal representations of music and standard notation. In addition, this paper seeks to determine how alternative representations of music through music technology can enhance students’ compositional abilities and concludes with a review of Impromptu, Hyperscore, GarageBand, and the O-Generator that can be used for composition.

Equality In Music Education: An Analysis And A Model Program, Steven J. Holochwost

Visions of Research in Music Education

This paper offers a review of the literature concerning how music is taught to school-aged children in America, in terms of frequency and content of instruction. It then outlines how music should be taught to children to optimize both the musical and the extra-musical benefits of music education, according to current research. A number of music education programs that successfully incorporate some elements of these research findings are then discussed. Finally, a model that incorporates the best elements of these programs is presented, along with guidelines for implementation. Throughout, the discrepancy between how music is taught and how it should …

Geodetic Model For Teaching Motion On The Earth's Spheroidal Surface, Boyd F. Edwards, John M. Edwards

All Physics Faculty Publications

We explore the forces that shape our spheroidal Earth and the forces that govern the motion of a puck that slides without friction on its surface. The Earth's stable spheroidal shape (apart from small-scale surface features) is determined by balancing the gravitational forces that hold it together against the centrifugal forces that try to tear it apart. The motion of a puck on its surface differs profoundly from motion on a sphere because the Earth's spheroidal deformations neutralize the centrifugal and gravitational forces on the puck, leaving only the Coriolis force to govern the motion. Yet the Earth's spheroidal deformations …

The Real Me: Shared Technology’S Impact On Status From The Lens Of Positioning Theory, Christina Nishiyama, Michael E. Nussbaum, Michael S. Van Winkle

College of Education Faculty Research

Participation in collaborative learning environments has demonstrated significant learning advantages due to opportunities for group members to contribute to shared problem-solving processes, shared goals, and co-elaboration of knowledge. Furthermore, research has shown that higher levels of social perceptiveness are positively correlated with higher levels of group performance. However, collaboration is not always successful, sometimes exhibiting imbalances of power and status. In this study, positioning theory and interaction analysis were used to investigate (a) interactions in four racially and gender-mixed groups (of three university students each) working with technology and (b) their negotiated positions of power and status. Results showed that …

Ionospheric F-Layer Dipole Flute Instability Effects On Electromagnetic Scattering In A Magnetohydrodynamic Plasma, Andrew J. Knisely

Theses and Dissertations

The ionosphere has significant impact on radio frequency (RF) applications such as satellites, over-the-horizon radar, and commercial communication systems. The dynamic processes effecting the behavior of the ionic content leads to a variety of instabilities that adversely affect the quality of RF signals. In the F-layer ionosphere, flute instability persists, appearing as two radial regions of high and low density perturbations elongated along the earth's geomagnetic field lines. The sizes of flute structures are comparable to the wavelengths in the high frequency spectrum. The objective is to characterize the high frequency scattering of an incident field by developing a 3D …

Budlayan, Jonathan N. Patricio, Jeanne Phyre B. Lagare, Susan D. Arco, Arnold C. Alguno, Antonio M. Basilio, Felmer S. Latayada, Rey Y. Capangpangan

Physics Faculty Publications

A straightforward approach to recycle waste expanded polystyrene (EPS) foam to produce polystyrene (PS) microfibers using the improvised centrifugal spinning technique is demonstrated in this work. A typical benchtop centrifuge was improvised and used as a centrifugal spinning device. The obtained PS microfibers were characterized for their potential application for oil adsorption. Fourier transform infrared spectroscopy results revealed similarity on the transmission bands of EPS foam and PS microfibers suggesting the preservation of the EPS foam’s chemical composition after the centrifugal spinning process. Scanning electron microscopy displayed well-defined fibers with an average diameter of 3.14 ± 0.59 μm. At the …

Examining The Effects Of Hydrology And Reclaimed Water Application On Nutrient Retention In Wetlaculture Mesocosms In Southwest Florida, Andrew Wilson

USF Tampa Graduate Theses and Dissertations

The substantial increase among agricultural and urban land use over the past century is widely regarded as the leading cause in a variety of negative environmental impacts, particularly regarding eutrophication of both salt and fresh surface waters. Usage of both synthetic and natural fertilizers on agricultural fields and residential lawns has increased significantly in order to achieve maximum crop yield and green lawns. The nitrogen and phosphorus in these fertilizers inevitably run off the landscape and into downstream surface waters. The geographic scale of this issue makes it a challenge to overcome, as targeting specific sources/polluters is nearly impossible. Landscape-scale …

Evaluation Of Centrosema Rotundifolium For Sand-Soil Savannas In Eastern Venezuela, I. Rodríguez, R. Schultze-Kraft, S. González

IGC Proceedings (1977-2023)

An evaluation of a collection of amphicarpic Centrosema rotundifolium showed considerable variability among the six accessions tested, regarding above- and below-ground seed production. Dry-season forage yields were very low but rainy-season yields reached acceptable levels. Contents of crude protein, P and Ca were intermediate to high (CP and P) or low (Ca). Three accessions are suggested for on-farm testing in association with grasses in order to explore the plant persistence implications of belowground seed production under practical conditions. Furthermore, the potential of this amphicarpic species for the conservation of sandy soils deserves attention.

Methodology To Evaluate Forage Legumes For Oversowing Grasslands In The Basaltic Region Of Uruguay, D. Real, J. Franco, J. Crossa

IGC Proceedings (1977-2023)

A methodology used to evaluate around 300 temperate and subtropical forage legumes for oversowing the native grasslands of the Basaltic Region of Uruguay is presented in a four-year plan using the minimum amount of seeds per accession and resources. Row-column experimental designs are used to reduce the error variance existing due to the large soil heterogeneity intrinsic to the Region. The ability of the species to grow and reproduce was measured and adjusted least square means were estimated to rank them. Cluster analysis was also useful to group species with similar behaviour overall traits. Preliminary results for the temperate species …

Reflecting On Belonging: Stories To Normalize College Transition And Encourage Engagement, Emily K. Suh, Sam Owens

Journal of Access, Retention, and Inclusion in Higher Education

Students’ capacity to develop a sense of belonging during the transition to college is recognized as a critical aspect of student retention. A lay theory of belonging was introduced on a regional, mostly-commuter campus of a midwestern public university during a summer bridge program for 21 upper-year student mentors and 29 incoming first-year students through a social-belonging growth-mindset intervention. Participants viewed a video of upper-year students and recent alumni sharing their personal stories of gaining a sense of belonging on campus, interspersed with facts about the transition to college. Students were asked to respond to writing prompts about the video. …

Detecting Perturbations In Seawater Carbonate Chemistry With The Δ44/40ca-Δ88/86sr Multi-Proxy, Jiuyuan Wang

Sustainability Seminar Series

Ocean acidification is one predictable consequence of rising atmospheric CO2. Understanding how the seawater carbonate chemistry changed during historical climate changes will help us better predict the ocean’s response to the present one. In this talk, I will introduce a novel means for tracking changes of seawater carbonate chemistry: the δ44/40Ca-δ88/86Sr multi-proxy. I will exploit emergent properties of δ44/40Ca and δ88/86Sr systems from two extreme climatic events: the Cretaceous Oceanic Anoxic Event 1a (OAE1a, ~120 Ma) and the Neoproterozoic Marinoan deglaciation (~635Ma).

Eigenfunction Restriction Estimates On Curves With Nonvanishing Geodesic Curvatures, Chamsol Park

Shared Knowledge Conference

There have been ways to study the eigenfunctions of the Laplace-Beltrami operator on compact Riemannian manifolds (without boundary), one of which is to consider the L^p estimates of the eigenfunctions restricted to submanifolds in the given manifolds. Burq, Gérard, and Tzvetkov, and Hu studied many types of these restricted estimates, and one of them was the L^2 restriction estimates on curves with nonvanishing geodesic curvatures. In this talk, we would like to talk about their logarithmic improved analogues, in the presence of nonpositive sectional curvatures in the given compact Riemannian manifolds.
