Impact of a place-based professional development experience on middle school teachers and their students
No full textThe United States faces a critical need for scientifically literate citizens, yet many students struggle to achieve science proficiency. To address this issue, educators must provide engaging learning experiences that foster a deep understanding of science and the natural world. One promising strategy is fostering sense of place to increase student engagement and learning. This study investigates the impact of a place-based professional development experience on middle school science teachers and their students. The study examined changes in teachers' and students' science content knowledge, place attachment, and place meaning. The findings suggest that science lessons based on a specific place can impact teachers’ content knowledge. Further, students demonstrated gains in both science content knowledge and sense of place. The implications of this study highlight the potential of place-based lessons to transform science teaching and learning. By providing teachers with the necessary tools and knowledge, we can empower them to create engaging and meaningful experiences that inspire students to become scientifically literate citizens
Evaluation of genome assemblies and annotations using publicly available platforms
No full textIntroduction/Objectives: Options for assembling the DNA pieces generated by short-read Illumina sequencing into a completed assembly or shorter contiguous regions for submission to the National Center for Biotechnology Information GenBank include purchased services, Python-based programs available from GitHub, and open source web-based platforms using graphical user interfaces. The goal of the present study was to evaluate assembly and annotation of a single strain of Serratia marcescens using programs available on four different web-based platforms: BV-BRC (BV-BRC.org), Galaxy (https://genome.usegalaxy.org.au/), KBase (kbase.us) and Proksee (proksee.ca/users/). Each of these allows users a free account with the ability to store data online and to export results, but each also has unique programs. Common to all are programs to evaluate read quality (such as FastQC), trim reads (such as Trimmomatic), assemble reads (Velvet, SPAdes and Unicycler), and analyze the assembly (Quast). The four platforms differ regarding the available annotation programs, which include Prokka, Bakta, RAST and DRAM.Methods: SeqCenter performed Illumina sequencing of a clinically isolated strain of S. marcescens, 131 Watkins. Read files were imported into accounts at each of the platforms. Two platforms, Proksee and BV-BRC, use an automated pipeline of programs to assemble reads into genomes. In Galaxy and KBase, each program was individually chosen and used. Once assembled and annotated, parameters were compared for the different assemblies and annotations.Results: Nine assemblies (5 on Galaxy, 1 on BV-BRC, 1 Proksee, and 2 on KBase) were completed. The SPAdes program on KBase was unable to be completed. Each of these 9 assemblies was then annotated using the annotation programs available on the platform: Prokka (Galaxy, KBase, Proksee), RAST (BV-BRC), DRAM (KBase) and Bakta (Proksee). The assembly length varied from 4.9 to 5.3 million base pairs (Mbp), with 7 assemblies being 5.2 Mbp. The longest contigs, 3.1 Mbp long, were obtained with Unicycler and Velvet on Galaxy, but the assembly with the fewest contigs was created with Unicycler on BV-BRC. The largest N50, which measures assembly contiguity, was 3.1 Mbp with Galaxy-based Unicycler. Results of the annotation programs on different platforms also varied. Six of the 10 assembly annotations found ~4700 coding sequences, while one (Prokka of the KBase Unicycler assembly) located 7100 coding sequences.Conclusions: These comparisons supported the conclusion that one version of the Galaxy Unicycler program would be the most appropriate assembly program to use for submission to GenBank, while several of the annotation programs (DRAM on KBase, Bakta on Proksee, and Prokka on Galaxy or Proksee) will yield comparative results

On-land manifestation of along strike transitioning of the Red Sea from continental rifting to sea floor spreading using aeromagnetic, satellite gravity, and remote sensing data
No full textThis doctoral dissertation examines the region between Ad Damm Fault Zone (AFZ) and the Fatima Fault Zone (FFZ) and harrat Rahat in the western Arabian Shield. The area of deformation under consideration exhibits a combination of brittle structures associated with Red Sea activity during the Cenozoic. These structures have overlaid ductile structures formed during the Precambrian. The volcanic rocks that formed during Cenozoic in the Harrats region are believed to potentially serve as the future route for the Red Sea floor spreading center. This project uses a combination of different geophysical and remote sensing methods separated as follows; Aeromagnetic studies have examined the on-land manifestation of the transitioning of the Red Sea from sea floor spreading to a continental rift. It indicated that there are evidence of reactivation: (1) the AFZ and FFZ largely control the old-drainage system. (2) Sharp difference in the elevation of the Red Sea topographic escarpment across the AFZ. (3) NNW- to NW-trending mafic dike swarms intrude the Precambrian crystalline basement rocks in Jeddah and Asir terranes. Gravity studies examined gravity anomalies and differences of upper and lower crust, subcontinental lithospheric mantle, and asthenosphere structure across the on-land manifestation of this transition. This study is the first attempt to measure the depth of Moho and LAB using a 2D model beneath AFZ and FFZ . The Results from this project modeling showed that the average thickness of the crust beneath the AFZ and FFZ is ~28 km and that of the upper crust is ~12 km. and showed thicker crust (~32 km) beneath the AFZ and the thickness of lithosphere beneath the AFZ and FFZ to be between ~58 km and ~68 km. Remote sensing studies have been used to map the Red Sea related brittle structure that follows the Cenozoic volcanic rocks. The information of these studies is compounded into three chapters in this dissertation. The project three indicated that there is a domal topographic vent trending N-NW which characterized late-stage continental drift. This research conclude that there is a possible pathway for a new sea flood spreading center a long AFZ and across Harrat
Evaluation of short and long-term performance of a dual-source heat pump
No full textA dual-source heat pump is a heat pump coupled with two heat sources/sinks, such as the ground and the air. Such solutions allow to balance the thermal load to the ground, shifting part of the heating or cooling thermal load to the finned coil heat exchanger and preventing the possible degradation of the long-term ground-source heat pump performance. In addition, a similar configuration can be more economically convenient than a ground source heat pump. Depending on the plant configuration and the boundary conditions (mainly climatic area), the control strategy to switch between the two heat sources and sinks is crucial to ensure good heat pump performance in the short and long-term operation of the system. This work investigates a control strategy to choose the value of switch temperature, which establishes the most favorable heat source or sink to be used by the heat pump. A dynamic model is developed using TRNSYS to study and predict the thermal and electrical behavior of double-source heat pumps, which can be used in the context of retrofitted and new buildings under different weather conditions. The modeled system simulates an existing commercial building, where a dual-source heat pump is installed and whose operation data are monitored
Unveiling hidden stories: Interactive digital humanities resources empower research on underrepresented communities
No full textIn three case studies, we show how the transformation from a static bibliography to an interactive digital humanities resource connects student researchers to the cultural heritage of often overlooked communities, including Indigenous artists and Indigenous architects and architecture. In addition to modernizing pre-existing metadata on Indigenous artists and the built environment of Oklahoma, we created an entirely new bibliography dedicated to the under-represented field of Indigenous Architecture of Oklahoma. These case studies show how unearthing and enhancing existing resources can help researchers develop new narratives about the history and culture of Oklahoma.Librar

Development and mathematical modeling of a metachronal paddling remotely operated vehicle
No full textMetachronal swimming is the primary underwater propulsion strategy many aquatic crustaceans use, varying in size from krill to lobsters. Characterized by the coordination of multiple swimming appendages moving in an oscillatory motion with a constant phase lag between adjacent appendages, metachronal swimming achieves high swimming speeds by taking advantage of unsteady hydrodynamic effects. Inspired by this widely observed swimming technique, a metachronal paddling-powered remotely operated vehicle (MP²ROV) was developed. On the MP²ROV, eight legs are actuated using one servomotor per leg, and a joint controller was used to prescribe kinematic parameters and phase lags to each leg. Two different models for its surge dynamics were developed by the desire to create a fully autonomous system eventually. The first model is a nonlinear ordinary differential equation derived from first principles and experimental data. In this model, each paddle is approximated as two plates oscillating about their edges with no fluid interactions between adjacent paddles. Using an assumed constant drag coefficient and experimentally informed joint angle trajectories, the total propulsive force is calculated as the sum of the drag force experienced by each paddle. The second model is a data-driven model where the total propulsive force is parameterized as a function of the stroke parameters by a neural network trained on thrust measurements. This model improves upon the prior by accounting for hydrodynamic interactions between paddles. A comparison between swimming performance and model predictions for the MP²ROV will be presented
