Synthesis And Antibacterial Evaluation For Some New Schiff-Bases Derived From P-Aminoacetanilide, Eman M. Hussain

Baghdad Science Journal

Derivatives of Schiff-bases possess a great importance in pharmaceutical chemistry. They can be used for synthesizing different types of bioactive compounds. In this paper, derivatives of new Schiff bases have been synthesized from several serial steps. The acid (I) was synthesized from the reaction of dichloroethanoic acid with 2 moles of p-aminoacetanilide. New acid (I) converted to its ester (II) via the reaction of (I) with dimethyl sulphate in the present of anhydrous of sodium carbonate and dry acetone. Acid hydrazide (III) has been synthesized by adding 80% of hydrazine hydrate to the new ester using ethanol as a solvent. …

Uniquely Tailored Ionic Materials For Implementation In Energy, Imagining, And Antibacterial Applications, Amanda Jalihal

Theses and Dissertations

In this dissertation, the novel class of ionic materials is explored. Ionic materials are easily tuned and tailored to fit a wide variety of applications. The synthesis of ionic materials is extremely simple and prompt. Briefly, two ionic moieties are joined electrostatically through a double displacement resulting in a new compound without complicated synthesis. This process leads to a close proximity of the ions which allows for enhancement of the FRET mechanism between a fluorophore and chromophore. A potential application of a FRET active ionic material is explored as a photosensitizer using IR820 and Nile Blue A. The ionic material, …

Overcoming Foreign Language Anxiety In An Emotionally Intelligent Tutoring System, Daneih Ismail

College of Computing and Digital Media Dissertations

Learning a foreign language entails cognitive and emotional obstacles. It involves complicated mental processes that affect learning and emotions. Positive emotions such as motivation, encouragement, and satisfaction increase learning achievement, while negative emotions like anxiety, frustration, and confusion may reduce performance. Foreign Language Anxiety (FLA) is a specific type of anxiety accompanying learning a foreign language. It is considered a main impediment that hinders learning, reduces achievements, and diminishes interest in learning.

Detecting FLA is the first step toward reducing and eventually overcoming it. Previously, researchers have been detecting FLA using physical measurements and self-reports. Using physical measures is direct …

Robust Color Image Encryption Scheme Based On Rsa Via Dct By Using An Advanced Logic Design Approach, Khalid Kadhim Jabbar, Fahmi Ghozzi, Ahmed Fakhfakh

Baghdad Science Journal

Information security in data storage and transmission is increasingly important. On the other hand, images are used in many procedures. Therefore, preventing unauthorized access to image data is crucial by encrypting images to protect sensitive data or privacy. The methods and algorithms for masking or encoding images vary from simple spatial-domain methods to frequency-domain methods, which are the most complex and reliable. In this paper, a new cryptographic system based on the random key generator hybridization methodology by taking advantage of the properties of Discrete Cosine Transform (DCT) to generate an indefinite set of random keys and taking advantage of …

Alexnet Convolutional Neural Network Architecture With Cosine And Hamming Similarity/Distance Measures For Fingerprint Biometric Matching, Ahmed Sabah Ahmed Al-Jumaili, Huda Kadhim Tayyeh, Abeer Alsadoon

Baghdad Science Journal

In information security, fingerprint verification is one of the most common recent approaches for verifying human identity through a distinctive pattern. The verification process works by comparing a pair of fingerprint templates and identifying the similarity/matching among them. Several research studies have utilized different techniques for the matching process such as fuzzy vault and image filtering approaches. Yet, these approaches are still suffering from the imprecise articulation of the biometrics’ interesting patterns. The emergence of deep learning architectures such as the Convolutional Neural Network (CNN) has been extensively used for image processing and object detection tasks and showed an outstanding …

Ecofriendly Control For Stored-Product Pest, Oryzaephilus Surinamensis (Order: Coleoptera, Family: Silvanidae), Fatma H. Galal

Baghdad Science Journal

Dates are considered one of the most important foods consumed in Arab countries. Dates are commonly infested with the sawtoothed grain beetle, Oryzaephilus surinamensis. Consequently, the date yield, quantity, and quality (economic value and seed viability) are negatively affected. This study was designed to investigate the effectiveness of air evacuation as eco-friendly and safe control method against adult O. surinamensis. Insects were obtained from the infested date purchased from a private store in sakaka city, Aljouf region, Saudi Arabia. Air evacuation (using a vacuum pump) and food deprivation were applied to O. surinamensis, and insect mortality was observed daily in …

Cytotoxic Activities, Determining Toxin, And Molecular Docking Of Ovary Pufferfish (Tetraodon Leiurus) In Singkarak Lake As Cancer Chemoprevention Candidate, Dewi Imelda Roesma, Djong Hon Tjong, Monica Mulnia Hanif

Baghdad Science Journal

The primary toxin class discovered in freshwater pufferfish is a category of neurotoxins called PSTs (Paralytic shellfish toxins) and pufferfish toxin has been observed to have biological, biochemical, and cytotoxic effects on cancer cell lines. Therefore, it is crucial to determine the cytotoxic activity, toxins present in the ovary of T. leiurus, and interaction between ligand (toxin compound) and receptors test. This study used the MTT method in the T47D cell lines, liquid chromatograph-tandem mass spectrometry (LC-MS/MS), and analysis of the molecular interaction using molecular docking. The ovary of T. leiurus had cytotoxicity on the T47D cell, having an IC50 …

Adverse Childhood Experiences And College Attainment: A Moderated Moderation Exploring Safe, Stable & Nurturing Relationships, Race/Ethnicity And Gender, Alicia Vincent Stires

Electronic Theses and Dissertations Archive

Abstract Statement of the Problem: This study aimed to understand the impact of exposure to ACEs in childhood on college attainment in adulthood and if safe, stable, and nurturing relationships (SSNRs) in childhood mitigate the risks of exposure to trauma through a contextual lens by exploring results by race/ethnicity and gender. Research: Exposure to adverse and traumatic experiences in childhood can adversely impact learning, behavior, and health outcomes throughout the lifespan (Shonkoff et al., 2012). Supportive adults that provide SSNRs can buffer adverse childhood events and help foster children’s resiliency by buffering or eliminating risk factors. Research has been limited …

One Man’S Trash, Jordan Tavan

Theses

This thesis explores perception through ambiguous mixed-media sculpture in order to create the potential for people to question their assumptions of what “is.” Judgments, categorization, and assumptions are big parts of the ways we make sense of our world. Often, we’re wrong about them. This artwork is created in response to the lifelong experience of existing outside the lines – the experience of breaking social rules and the desire for others to realize the potential for multiple truths.

Journal on Empowering Teaching Excellence

Access the online Pressbooks version of this article here.

In the world of higher education, expectations of college-level instructors have shifted significantly in the last few years due to the COVID-19 global pandemic. Instructors were required to be more flexible than ever before, oftentimes across different modalities. This essay models an evidence-based teaching method, interteaching (IT), that was originally created for use in a traditional face-to-face classroom and suggests an adaptation of that method for a hybrid classroom. The theoretical framework of IT is explained and an adaptation of IT for hybrid classrooms is provided with a specific college-level course …
