Development Of Polymer Blends Of Poly(Methyl Methacrylate) And Poly(Lactic Acid) As Denture Base Material, Taksid Charasseangpaisarn

Chulalongkorn University Theses and Dissertations (Chula ETD)

Nowadays, poly(lactic acid) (PLA) usage in dentistry is increasing due to its mechanical and physical properties close to those of poly(methyl methacrylate) (PMMA). However, the thermal properties of PLA is poor due to its low glass transition temperature, which leads to distortion when used in high temperatures. The blending of polymers is an easy and cost-effective method to improve the desired properties of polymers. The objective of this study was to develop the PMMA/PLA blend in various compositions for use as denture base materials. The three PMMA/PLA blend compositions (M75, M50, and M25) were conducted by melt blending with a …

Notch2 Activation Of Full-Length And Truncated Recombinant Jagged1 Fused With Human Igg1 Fc Produced In Mammalian Expression System, Y Tran Nhu

Chulalongkorn University Theses and Dissertations (Chula ETD)

Osteoporosis associated with old ages has emerged in 21st century as an increasing issue. To stimulate the mineral deposition in bone cells, Jagged1 (Jag1) protein has been demonstrated to trigger mineralization via Notch signaling pathway by binding to Notch2 receptor. Therefore, the Jag1 protein is one of promising candidates for osteoporosis treatment. However, Jag1 consisting of 1218 amino acids is infeasible to apply in clinical uses. Here we engineered Jag1 into truncated proteins containing key domains, Delta–Serrate–Lag-2 domain, N-terminal C2 domain and several epidermal growth factor–like domains which could be responsible for the binding of Notch receptor. To ensure the …

With optimized condition at room temperature in our hand, isothiocyanate derivatives were isolated by column chromatography in low to high yields (37-94%). Additionally, the aqueous medium can be recycled at least two cycles without significantly losing the yield of products. …

The Democracy Crisis In El Salvador: An Overview, Mneesha Gellman

Emerson Authors, Researchers, & Creators

This paper examines the current democratic breakdown in El Salvador, identifying factors and events in the country from 2019 to 2022 that have led to democratic backsliding, the process by which democracy as a political system loses traction. Indicators of backsliding show that El Salvador’s shared characteristics of liberal democracy — free and fair electoral procedures accessible to all; freedoms of the press, to assembly, and to express political opinions; the rule of law; and basic human rights protections — are in peril. Given the events of the last several years under President Nayib Bukele, El Salvador’s regime more closely …

Unsettling Settler Colonialism In Words And Land: A Case Study Of Far Northern California, Mneesha Gellman

Emerson Authors, Researchers, & Creators

This article examines two case studies of unsettling settler colonialism in the far north of California: the inclusion of Yurok language electives in public high schools, and land return to the Wiyot Tribe. These two cases demonstrate repertoires of Indigenous resistance to historic and ongoing culturecide—the killing of culture—and show what unsettling settler colonialism looks like in the region. The central research question in this article is: How does unsettling happen in settler colonial-controlled public institutionalised spaces in far northern California? I argue that acts of Indigenous voice-raising and place-making constitute forms of resistance to ongoing erasure of Indigenous peoples …

On Rotationally Driven Nonlinear Inclined Polymeric Jet With Gravity Effect, Daniel N. Riahi, Saulo Orizaga

School of Mathematical & Statistical Sciences Faculty Publications

We consider rotationally driven nonlinear polymeric fiber jet, whose centerline is in an inclined plane, in the presence of gravity force. An empirical viscosity model is used for the polymeric fluid flow to investigate properties of the rotating inclined polymeric fiber jet. The aim of the study is to understand properties of such inclined fiber jet shape, which can be due to orientation change of an orifice in a rotating spinneret that generates such jet. Perturbation, asymptotic, scaling and numerical techniques are used to determine the nonlinear steady solutions for the jet quantities for different values of the parameters due …

The Entity Attorney-Client Privilege Meets The Twenty-First Century: Rethinking Functional Equivalent Analysis In The Time Of A Nonemployee Workforce., Grace M. Giesel

Faculty and Staff Scholarship

Courts have struggled with whether an entity’s attorney-client privilege can protect communications between the entity’s lawyer and a nonemployee who has information the entity’s lawyer needs to best advise the entity. The nonemployee might be a former employee. But increasingly in recent times, the nonemployee is an individual who was never an entity employee. Corporations and other entities have incorporated nonemployees in their economic enterprises in all sorts of roles—roles employees may have held in the past. Many courts have accepted that the privilege can apply to communications involving former employees.

When faced with nonemployees who are not former employees, …

On (Not) Seeing The Chicken: Perdue, Animal Welfare, And The Failure Of Transparency, Calvin Coker, Rachel A. Coker

Faculty and Staff Scholarship

In this essay, we analyze Perdue’s animal welfare campaign from 2016 to 2020 to isolate how demands for transparency are mediated and subverted by Perdue’s public facing rhetoric. Though Perdue’s annual releases and commitments to change nominally constitute a victory for animal welfare advocates, the company’s campaign enacts transparency as a sort of publicity for the company that belies marginal gains for the lives of chickens and may ultimately result in increased meat consumption. In providing trackable metrics, offering paternalistic justifications for their treatments of chickens, and through strategic omissions of language and visuals, Perdue satisfies demands for transparency without …

Cambridge 1629 Anglican Trilogy, Dale B. Billingsley

Faculty and Staff Scholarship

In 1629, Thomas and John Buck, Cambridge University Press printers, published three texts—the Book of Common Prayer, the Bible and the Whole Book of Psalmes (known as the “Metrical Psalter”)—that were often bound together in one volume [UL], 1 one copy of which is now on permanent loan to the Archives & Special Collections of Ekstrom Library, University of Louisville. We do not know with any certainty when UL was bound, but because the KJV second edition was published in 1638, with many scholarly corrections based on the original languages, we can assume that the three texts were bound together …

Electrical and Computer Engineering Faculty Research & Creative Works

The growing popularity of big data and machine learning applications call for a more powerful and energy-efficient way to execute deep learning workflows. Neuromorphic chips provide a potential solution, as they attempt to mimic the neuronal architectures in human brain and show great potentials in reducing energy consumption in the order of magnitude and also improve the computational performance. However, the fabrication process for neuromorphic chips is costly and currently based on trial-and-error, which adds complexity to the design process. In this paper, we address this challenge by designing and developing machine learning guided microfabrication process for Resistive Random Access …

Longevity Of An Immunocontraceptive Vaccine Effect On Fecundity In Rats, Rebecca Pinkham, Douglas C. Eckery, Richard E. Mauldin, M. Gomm, F. Hill, F. Vial, G. Massei

United States Department of Agriculture Wildlife Services: Staff Publications

Increases in human-wildlife conflicts alongside cultural shifts against lethal control methods are driving the need for alternative wildlife management tools such as fertility control. Contraceptive formulations suitable for oral delivery would permit broader remote application in wildlife species.

This study evaluated the contraceptive effect and immune response to two novel injectable immunocontraceptive formulations targeting the Gonadotropin Releasing Hormone (GnRH): MAF-IMX294 and MAF-IMX294P conjugates, both identified as having potential as oral contraceptives. The study also explored whether in multiparous species immunocontraceptives may either totally prevent reproduction or also affect litter size.

Female rats, chosen as a model species, were given three …
