Expanding Potential Dental Applications Of Glass Ionomer Cement By Incorporating With Nano-Hydroxyapatite, Kifayah K. Thbayh, Rafid M. Albadr, Kareema M. Ziadan, Béla Fiser

Karbala International Journal of Modern Science

Glass ionomer cement (GIC) is a common restorative material in dentistry, but it exhibits relatively weak mechanical properties. The present study focuses on incorporating nano-hydroxyapatite (nHAP) with different ratios (1, 3, 5, and 7wt%) in GIC to improve its properties. Mechanical properties, sorption, solubility, and diffusion coefficients after storage in distilled water for 60 days were studied. The highest sorption was measured at 7%wt (46.66 µg/mm3), and the lowest solubility was in the case of the sample containing 5% (29.166 µg/mm3). Moreover, the highest value of diffu-sion coefficient was 8.5 mm/s in the case of the sample with 7%wt nHAP. …

Biofunctionalization Of Polyetheretherketone Implant Material By Bone-Forming Peptide-2 Immobilization, Mustafa S. Tukmachi, Hikmat J. Abdul-Baqi, Falah H. Hussein

Karbala International Journal of Modern Science

Polyetheretherketone (PEEK) has favorable biomechanical properties to be used as an implant material. Unfortunately, it is hydrophobic and does not promote cellular adhesion, which could result in poor integration with bone tissue. Bio-functionalization of PEEK surface with osteogenic peptides derived from bone extracellular matrix proteins is an excit-ing approach to encourage bone formation around the implant. In the current study, bone-forming peptide-2 was immo-bilized on PEEK surface using two different methods, using dopamine and a diglycidyl ether as conjugate compounds, respectively. Peptide quantification test revealed that the two strategies resulted in the most amount of peptides were attached with 0.5 …

Electrochemically Synthesized Biogenic Silver Nanoparticles Using Green Tea Extract As A Promising Antioxidant, Dhony Hermanto, Nurul Ismillayli, Irmawanti Irmawanti, Ilfa Fathulloh, Diska Nila, Ulul Khairi Zuryati, Handa Muliasari, Rahadi Wirawan

Karbala International Journal of Modern Science

The role of an antioxidant in cancer prevention has led to the development of its synthesis, including green tea-capped silver nanoparticles (AgNPs), which are natural antioxidants. The biogenic AgNPs were synthesized electrochemically from pure silver wire using local green tea extract for the first time, with a characteristic peak at 420 nm. The method shortened the reaction time and produced long-term stable and narrow-size distribution nanoparticles. The spherical AgNP with an average size of ~17 nm was confirmed in TEM analysis. Furthermore, FTIR analysis and phytochemical assays revealed that the -OH group of flavonoids and terpenoids was responsible for the …

In Search Of Belonging Online: Achieving Equity Through Transformative Professional Development, Michelle Pacansky-Brock, Michael Smedshammer, Kimberly Vincent-Layton

Journal of Educational Research and Practice

Abstract

Online classes hold the potential to expand college access to Black, Latino/a/x, Indigenous, and other students of color who must be supported to diversify the STEM workforce. Research shows that fostering belonging is key to the academic success of students from minoritized groups. However, online classes often lack interpersonal interactions and are often left out of research about the positive impacts of belonging. This paper summarizes an equity-focused STEM grant project that produced an openly-shared online professional development program, the Humanizing Online STEM Academy. Through the Academy, STEM faculty are introduced to a model of humanized online teaching that …

Illuminating Chinese Aesthetics With Kant’S Account Of Genius? Possibility And Difficulty, Kefu Zhu

Comparative Philosophy

Many scholars interpret Chinese Aesthetics with the Kantian theory of genius because they seem to form a parallel: similar innate and spontaneous mental talents that exceed normal cognition and imagination generates beautiful arts with similar extraordinary qualities. I argue that projecting Kant’s genius to illuminate the creative power analogically, i.e., the carefree-wandering mind, is infeasible. The theory of genius assumes a critical project that stipulates a valuable way to exercise the power of judgment. Genius is only a postulated idea for successfully making aesthetic judgments on artworks. In contrast, the carefree-wandering mind assumes a Daoist metaphysical-ethical theory centering on the …

The Best Confucian Hybrid Meritocracy-Democracy For Liberal Democracies, John J. Park

Comparative Philosophy

Several contemporary Confucian philosophers have posited differing hybrid views fusing meritocracy to democracy. There is a good deal of interest in a meritocracy in contemporary Confucian thought, and such a view perhaps should receive more serious consideration in liberal democratic thought since it may make for a stronger form of government when appended to democracy. In this paper, four contemporary hybrid theorists who combine elements of a meritocracy with a democracy are critically analyzed concerning an ability for their views to be instantiated in liberal democracies for the legislative branch only. Finally, I provide a modified hybrid view for the …

The Methodology Of Multiple Regressions For Gdp Per Capita For Nations In The World Between 0 Ce And 1940, Robert Rogers

The Journal of Economics and Politics

A reduced-form model of GDP per capita is estimated using the classical econometric method and two Bayesian techniques, Extreme Bounds Analysis (EBA) and Bayesian Analysis of Classical Estimation (BACE) for the two millenniums. For several variables, such as the impact of colonialism, the Goldstone hypothesis of efflorescence increasing economic growth, and the impact of technology, this paper lends support, especially when the Bayesian methods are applied. Other results are mixed. Generally, the results support use of Bayesian methods by eliminating hypotheses that are not consistently supported over all models.

Skin Stories And Family Feelings: The Contradictions Of Skin Picking In Mother And Daughter, Katrina Jacinto

Crossings: Swarthmore Undergraduate Feminist Research Journal

Skin picking, otherwise known as dermatillomania, is considered to be a medical disorder by the DSM-5. However, the embodied experiences of skin picking in myself and my mother do not align with the neat definitions offered by psychiatry. Through autoethnographic material and an ethnographic interview with my mother, I argue that skin picking is a bodily technique that is pathologized through stigma. In particular, I suggest that skin picking reveals the body as a polyvalent entity, in which the same features and practices take on different meanings in different bodies. This frames the discrepancies between mine, and my mother's, experiences. …

Malintzin: La Mujer Americana, Alma D. Elías Nájera

Crossings: Swarthmore Undergraduate Feminist Research Journal

Malintzin was a controversial Indigenous woman whose contributions to the Aztec conquest raised questions about what it meant to be a traitor with a limited agency. This essay recontextualizes Malintzin’s demonized identity and challenges masculinist sociocultural curations of gender, history, and knowledge production by infusing feminist theory into the cultural imaginaries of gender and racial stratification. By reintroducing Malintzin as a feminist emblematic figure trying to regain selfhood within an exploitative White cisheteropatriarchal society, her existence gives voice to those silenced by the violence of colonization, Manhood, and gender oppression. To do this, the author takes up the work of …

Hija De La Chingada: Visibility And Erasure Of La Malinche In Contemporary Mexican Discourse, Tania Del Moral

Crossings: Swarthmore Undergraduate Feminist Research Journal

The mystification and subsequent reduction of La Malinche in Mexican national discourse presents a problem in which patriarchy and colonialism bind the native Mexican women into two archetypes: either traditional or treacherous. Historical accounts have fallen short of describing the woman behind the myth of La Malinche, further compartmentalizing her into a traitor to her people. Scholars such as Octavio Paz and Gloria Anzaldúa have illustrated her subjugation and erasure, highlighting this binary. This paper, however, considers a postcolonialist perspective to analyze La Malinche's story as one of erasure; particularly the ways that language was used by the Spanish Crown …

Àṣẹ After Man: The Rupture Of The Christian-Colonial Project As Decolonial Ceremony, Eden Segbefia

Crossings: Swarthmore Undergraduate Feminist Research Journal

This project is a theoretical exploration of the Yoruba concept of àṣẹ and its role in unsettling the hierarchies imposed by Christian colonialism. Sylvia Wynter's explanation of the ways in which Christian colonialism has affected the very concept of Man proves crucial here. Àṣẹ is an example of a decolonial concept because of its ability to rearrange animacy, especially as it is conceived in Western European epistemology. Wynter and other interlocutors are utilized to support this argument and imagine new possibilities in considering the relationships between Christian colonialism, alterity, plasticity, and animacy.

Queer Ecologies: A Final Syllabus/Zine Product Of Our Independent Study, Yeh Seo Jung, Ray Craig

Crossings: Swarthmore Undergraduate Feminist Research Journal

This zine is the product of our independent study course Queer Ecologies, which is an exploration of bio-social systems using a queer and feminist theoretical lens. We aim to look critically at knowledge formation and construct alternative visions for more just and sustainable relationships between science, nature, and ourselves. While queer theory most directly interrogates the normative structure of heterosexuality both in humans and in biology more broadly, these studies include analyses of hierarchy, power, and value. Queer Ecology can be used to examine phenomena such as climate change, extinction, pollution, species hierarchies, agricultural practices, resource extraction, and human population …

Masculinized Sovereignty: Understanding Violence Towards Mice And The Nonhuman, Anisha Prakash

Crossings: Swarthmore Undergraduate Feminist Research Journal

This paper attempts to analyze how the definition of the normative “human” categorizes bodies that represent alternative political order against settler colonialism, and how the subjects that go against the dominant ideal of human are prohibited from living a free life, if not altogether eliminated. While conducting research, I view the lab as a site of social advancement where the differences between humans and nonhumans create a community of shared purpose. An interrogation of the laboratory as a site of violence can help us better understand how the State’s capitalist modes of advancement and production harm those of indigenous people, …

Sitting Here With You In The Future: Reimagining The Human Through Digital Art, Jared Z. Sloan

Crossings: Swarthmore Undergraduate Feminist Research Journal

This paper presents a novel construction of the Human that arises from digital art. Taking an interdisciplinary approach incorporating perspectives from queer theory, afropessimism, science and technology studies, and more, I analyze the works of three digital artists: Lucas LaRochelle, Arafa Hamadi, and Natalie Paneng. I chart the ways in which these artists negotiate borders between the physical and digital, human and non-human, and real and fantastical to challenge hegemonic Western ideas about humanity and the individual. I claim that by restricting the information available to the user in various ways, the picture of the Human that emerges from each …

Habitat Equivalency Analysis Software to Facilitate Calculation of Compensatory Restoration following Natural Resource Injury

Habitat Equivalency Analysis (HEA) is a means to determine the amount of compensatory restoration required to provide services that are equivalent to the interim loss of natural resource services following injury. The lost services are calculated from the time of injury through the recovery process. Recovery could be either via natural recovery or active restoration. The compensatory restoration services are calculated from the time of commencement through process of the chosen restoration. An injury to natural resources therefore involves a time component during which the ecological …

Pbl, Change Or Risk Irrelevance: A Friendly Warning, Virginie Servant-Miklos, Diana Dolmans, Thomas Ryberg

Health Professions Education

The world is already facing the consequences of climate change and biodiversity collapse, yet current trends suggest a far more difficult future in which the existence of human civilization is at stake. This commentary addresses the PBL community's lukewarm engagement with sustainability questions with a friendly warning. Unless PBL practitioners and scholars take the full measure of the emergency and change in proportion to the threat, PBL risks becoming irrelevant. Several avenues for changing PBL in a more sustainable direction are suggested, but this commentary is an invitation for all PBL scholars and educators to come together and bring forward …

Larval Dispersal Patterns And Connectivity Of Acropora On Florida’S Coral Reef And Its Implications For Restoration, Samantha King, Antoine Saint-Amand, Brian K. Walker, Emmanuel Hanert, Joana Figueiredo

Marine & Environmental Sciences Faculty Articles

Since the 1980s, populations of Acropora cervicornis and A. palmata have experienced severe declines due to disease and anthropogenic stressors; resulting in their listing as threatened, and their need for restoration. In this study, larval survival and competency data were collected and used to calibrate a very high-resolution hydrodynamic model (up to 100m) to determine the dispersal patterns of Acropora species along the Florida’s Coral Reef. The resulting connectivity matrices was incorporated into a metapopulation model to compare strategies for restoring Acropora populations. This study found that Florida’s Coral Reef was historically a well-connected system, and that spatially selective restoration …

The Effects Of Salinity And Acetaminophen On The Aquatic Snail Physa Acuta, Michelle Sackey-Ansah, Megan Mackey, Daniel Elias, Jason Doll, Alyssa Brookhart

Journal of the South Carolina Academy of Science

Pharmaceuticals are increasingly detected in water bodies, and their presence can negatively impact aquatic organisms. This effect can be amplified when combined with increasing salinity in freshwater ecosystems. Acetaminophen is a widely used analgesic that is commonly found in river, streams, and waters where it is discharged directly. Therefore, organisms present in these locations (e.g., insects, snails, amphibians, and fish) are likely to be affected by acetaminophen. In this study, we determined the effects of elevated salinity (0.68 g/L), acetaminophen (500 µg/L) and combined elevated salinity (0.68 g/L) and acetaminophen (500 µg/L), on the growth, reproduction, and movement of the …

A Process Evaluation Of Post-Secondary Programs For High Functioning Students On The Autism Spectrum, Richard A. Spirito Jr.

Seton Hall University Dissertations and Theses (ETDs)

ABSTRACT

The purpose of this study was to evaluate how the post-secondary programs in the Mid-Atlantic region of the United States are supporting the needs of students with autism spectrum disorder (ASD) and preparing them for future independence.

According to the CDC (Centers for Disease Control and Prevention), the number of children diagnosed with autism spectrum disorder is on the rise. In 2000, one in 150 children were identified with autism spectrum disorder. That number rose to one in every 44 children in the United States that have been identified with autism spectrum disorder in 2010.

Antibody-Dependent Enhancement Activity Of A Plant-Made Vaccine Against West Nile Virus, Haiyan Sun, Dhiraj Acharya, Amber M. Paul, Huafang Lai, Junyun He, Fengwei Bai, Qiang Chen

Faculty Publications

West Nile virus (WNV) causes annual outbreaks globally and is the leading cause of mosquito-borne disease in Unite States. In the absence of licensed therapeutics, there is an urgent need to develop effective and safe human vaccines against WNV. One of the major safety concerns for WNV vaccine development is the risk of increasing infection by related flaviviruses in vaccinated subjects via antibody-dependent enhancement of infection (ADE). Herein, we report the development of a plant-based vaccine candidate that provides protective immunity against a lethal WNV challenge mice, while minimizes the risk of ADE for infection by Zika (ZIKV) and dengue …

Anaerobic Toluene Biodegradation Potential At A Superfund Site Where Toluene Biosynthesis Was Observed, George Carson

LSU Master's Theses

At a Superfund site near Baton Rouge, LA, the subsurface injection of molasses has been used to stimulate anerobic reductive dechlorination of halogenated organic compounds (e.g., 1,2-dichloroethane and vinyl chloride) present in the groundwater. Following some molasses injections, temporary accumulation of toluene and p-cresol was observed in the groundwater. Accumulation of these aromatic hydrocarbons, which were not detected in the molasses, has been attributed to anaerobic biotransformation of the amino acids phenylalanine and tyrosine. Experiments reported here were conducted in support of an effort to determine if toluene biodegrading bacteria were present in the area where anaerobic toluene accumulation was …
