Preparation And Characterization Of Salvia Triloba Extract And Evaluation Of Its Cytotoxic Effect On Bone Cancer Cell Line, Basma Hossam Abdelmonem

Theses and Dissertations

Background: Osteosarcoma is a tumor of mesenchymal origin characterized by uncontrolled production of immature osteoid tissue. It is more common in children and adults over the age of 65. Many studies reported the cytotoxic effect of many plant extracts, including Salvia triloba, on different cancer cell lines when used alone or in combination with other chemotherapeutic agents.

Methods: In our study, the methanolic extract obtained from the air-dried leaves of Salvia triloba leaves from Palestine was screened for its total phenolic and flavonoid contents. The major components of phenolics and flavonoids were detected using LC-QToF-MS technique. The two phenolics …

Perceptions Of The Culinary Art Community On Their Higher Education Programs In Egypt: The Way Forward, Kadria Ali Abdel Motaal

Theses and Dissertations

Culinary art education used to have a narrow focus that forgoes its richness and ignores its infiltration into economic, political, and cultural aspects within society. Recently the world witnessed an evolution in this field of study as it reached tertiary education institutions. However, in Egypt, culinary art studies are integrated into hospitality education and are still confined to a shallow concept. This study aimed to explore the perception of the culinary art community in Egypt on their higher education programs from a sociocultural perspective. It also explored the possible new frameworks, and core competencies to improve culinary arts higher education …

Multicollinearity Applied Stepwise Stochastic Imputation: A Large Dataset Imputation Through Correlation‑Based Regression, Benjamin D. Leiby, Darryl K. Ahner

Faculty Publications

This paper presents a stochastic imputation approach for large datasets using a correlation selection methodology when preferred commercial packages struggle to iterate due to numerical problems. A variable range-based guard rail modification is proposed that benefits the convergence rate of data elements while simultaneously providing increased confidence in the plausibility of the imputations. A large country conflict dataset motivates the search to impute missing values well over a common threshold of 20% missingness. The Multicollinearity Applied Stepwise Stochastic imputation methodology (MASS-impute) capitalizes on correlation between variables within the dataset and uses model residuals to estimate unknown values. Examination of the …

Examining Dimensionality And Validity Of The Academic Integrity Survey Instrument, Zhidong Zhang, Luis Garcia

Teaching and Learning Faculty Publications

Dimensional reduction is one of the methods to ensure the quality of a questionnaire. This study examined two methods to reduce the dimension of the questionnaire: multidimensional scaling (MDS) and exploratory factor analysis (EFA). The questionnaire, Awareness of Academic Dishonesty consists of 30 questions. Participants included 110 college students. Multidimensional scaling analysis reduced the multidimensions to essentially two dimensions. The exploratory factor analysis reduced the multidimensions to three dimensions. MDS allowed the researchers to evaluate the questionnaire items by looking at the similarities of these data points. EFA provided an alternative thought about the construct of the questionnaire.

Timing And Magnitude Of Drought Impacts On Carbon Uptake Across A Grassland Biome, Andrew Felton, Gregory R. Goldsmith

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Although drought is known to negatively impact grassland functioning, the timing and magnitude of these impacts within a growing season remains unresolved. Previous small-scale assessments indicate grasslands may only respond to drought during narrow periods within a year; however, large-scale assessments are now needed to uncover the general patterns and determinants of this timing. We combined remote sensing datasets of gross primary productivity and weather to assess the timing and magnitude of grassland responses to drought at 5 km² temporal resolution across two expansive ecoregions of the western US Great Plains biome: the C₄-dominated shortgrass steppe and …

Named Entity Recognition From Biomedical Text, Maged Guirguis

Theses and Dissertations

As vast amounts of unstructured data are becoming available digitally, computer-based methods to extract relevant and meaningful information are needed. Named entity recognition (NER) is the task of identifying text spans that mention named entities, and to classify them into predefined categories. Despite the existence of numerous and well-versed NER methods, the bio-medical domain remains under-studied. The objective of this research is to identify an efficient technique for NER tasks from biomedical data. This is achieved by investigating using deep learning technologies namely pre-trained BERT [1] model and its variances SciBERT [2] and BioBERT [3]. Preprocessing the data before passing …

Invisibility And Dis-Identification Of Algerian Women: Feminist Jurisprudence Eyes On The Legal Provisions Related To Personal Status And Criminal, Sophia Lina Meziane

Theses and Dissertations

Much of the debate around women’s rights in legal systems focuses on the increase of protection as a legal mechanism for approaching and guaranteeing gender equality. Yet, what extensive or comprehensive analysis has been done on how effective such laws are when applied? This thesis discusses the extent to which a feminist legal theory, separate and distinct from the patriarchal legal system, can demonstrate how an Islamic or Napoleonic order is conceptually another male rationality. While one could possibly identify inefficiencies of laws proclaiming equality and protection for women, the context of the question is inevitably entrenched in the very …

Minimal Auxiliary Basis Set Approach For The Electronic Excitation Spectra Of Organic Molecules, Zehao Zhou, Shane M. Parker

Faculty Scholarship

We report a minimal auxiliary basis model for time-dependent density functional theory (TDDFT) with hybrid density functionals that can accurately reproduce excitation energies and absorption spectra from TDDFT while reducing cost by about \change{two} orders of magnitude. Our method, dubbed TDDFT-ris, employs the resolution-of-the-identity technique with just one $s$-type auxiliary basis function per atom for the linear response operator, where the Gaussian exponents are parametrized across the periodic table using %using tabulated atomic radii with a single global scaling factor. By tuning on a small test set, we determine a single functional-independent scale factor that balances errors in excitation energies …

Mechanisms For Change: A Theoretical Pathway For A School-Wide Social–Emotional Learning Initiative In An Urban Middle School, Gwyne W. White, Danielle R. Hatchimonji, Esha Vaid, Christopher C. Simmons, May Yuan, Angela Wang, Maurice J. Elias

Psychology Faculty Publications

Introduction: Investment in academic instruction without complementary attention to the social-emotional environment of students may lead to a failure of both. The current study evaluates a proposed mechanism for change, whereby academic achievement occurs as a result of the social-emotional learning environment impacting behavioral (discipline) outcomes.

Methods: We tested the hypothesized model during each year of a 3-year intervention to determine whether the relations among these constructs held potential as a pathway for targeted improvement.

Results: Path analysis for each year demonstrated excellent fit [Year 1: χ2 (19) = 76.16, CFI = 0.99, RMSEA = 0.05,TLI = 0.98; Year 2: …

Primary Production Modeling Identifies Restoration Targets For Shifting Shallow, Eutrophic Lakes To Clear-Water Regimes, Leighton King, Janice Brahney, Scott Daly, Michael J. Paul, Kateri R. Salk, Soren Brothers

Watershed Sciences Faculty Publications

Benthic primary production (BPP) plays an important functional role in lakes, improving water quality by stabilizing clear-water regimes. Shallow, eutrophic lakes lacking BPP communities can be difficult to restore because self-stabilizing feedbacks of phytoplankton dominance can impede the establishment of BPP. BPP in lakes is light limited, and ecosystem models can provide guidance for determining the water clarity necessary to re-establish BPP dominance. We developed a multi-tiered framework for the restoration of shallow, eutrophic lakes that incorporates multiple turbidity sources, lake morphometry, and water-level fluctuations to determine water-clarity thresholds above which BPP dominance may be established. We present a case …

Classifying Emotions And Toxicity On Audio To Text Signals From Videos On Youtube, Connice Trimmingham

Theses and Dissertations

Recent technological advancements have pushed humans past the boundaries of a computer screen. They have facilitated human-computer-interaction that were once inconceivable including emotional and audio engagement. Users are now able to utilize technology in more human-like ways and instantaneously transfer depth of opinions and emotions. This global prominence of modern technology, specifically with social media, has spawned a new norm, in which it is now a reasonable expectation of encountering high online toxicity on social media platforms. In addition, the complexities of human emotions make it challenging to determine whether toxic comments trigger certain emotions or vice versa. This study …

Estimated Impact Of Low Isolate Numbers On The Reliability Of Cumulative Antibiogram Data, Christian Tran, John Hargy, Bryan Hess, Matthew Pettengill

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Antibiograms are cumulative reports of antimicrobial susceptibility results that are used to guide the selection of empirical antibiotic therapy. Although Clinical and Laboratory Standards Institute (CLSI) guidelines recommend including only organisms that have at least 30 isolates in an antibiogram, previous studies demonstrated that adherence to this recommendation is highly variable. This paper aims to model the impact of small sample sizes on expected levels of error in cumulative antibiograms by comparing percent susceptibility results for random samples to those of the larger, entire data set. The results demonstrate relatively high error rates when utilizing low numbers of isolates in …

Electro- And Photoactivation Of Silver–Iron Oxide Particles As Magnetically Recyclable Catalysts For Cross-Coupling Reactions, Qi Wang, Zhongxia Shang, Haiyan Wang, Alexander Wei

Department of Chemistry Faculty Publications

Colloidal Ag particles decorated with Fe3O4 islands can be electrochemically or photochemically activated as inverse catalysts for C(sp2)–H heteroarylation. The silver–iron oxide (SIO) particles are reduced into redox-active forms by cathodic charging at mild potentials or by short-term light exposure, and can be reused multiple times by magnetic cycling without further activation. A negative shift in the reduction peak is attributed to an overpotential produced by surface Fe3O4 which separates residual Ag ions or clusters from bulk silver. The catalytic efficiency of SIO is maintained even with acid degradation, which can be countered simply by adding water to the reaction …
