Applied Environmental Research

In this work, biochar synthesized from orange peel modified with magnetite was used as an alternative magnetic adsorbent for dye removal. The magnetization of the synthesized biochar was done using the co-precipitation method. The obtained composite was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Raman spectroscopy. The efficiency of magnetized biochar (OPB/Fe3O4) was studied in the process of removing crystal violet (CV) from an aqueous solution at different temperatures. The experimental data obtained for the kinetic studies were better fitted to the pseudo-second-order model, and the isotherms data were well fitted to the Langmuir model. The results …

Performance Of Porous Substrates For Domestic Wastewater Treatment Under Prolonged Hydraulic Retention Time, Pakawat Janyasupab, Arunothai Jampeetong

Applied Environmental Research

Physicochemical characteristics of porous substrates (longan biochar, corn biochar, and pumice) including specific surface area (SSA), pore volume (Vp), and cation exchange capacity (CEC) were determined. Longan biochar had the highest SSA, Vp, and CEC, followed by corn biochar and pumice. Then, columns filled with each of these 3 substrates together with gravel as a control treatment, were evaluated to compare wastewater treatment efficiency under different hydraulic retention times (HRTs). Each system had been acclimatized with wastewater for 8 weeks. Then, influent and effluent were analyzed at 1, 3, 5, and 7 day intervals. Water analysis revealed that biochar-based systems …

Applied Environmental Research

Biochar made from agricultural waste products can be used as a low-cost adsorbent targeting dissolved organic matter (DOM). In water treatment plant (WTP), DOM reacts with chlorine-based disinfectant and forms carcinogenic disinfection by-products. The objective of this study was to investigate the applicability of bamboo biochar derived from wood vinegar production waste as an adsorbent for DOM removal and subsequently trihalomethane formation potential (THM-FP) reduction. Raw biochar (BCRaw) and 800°C post-heated biochar (BC800) was tested for its surface characteristics including scanning electron microscopy, Fourier transform infrared spectroscopy and Brunauer, Emmett and Teller analysis. The post-pyrolysis treatment increased the surface area …

Spatial Distribution Of Bioavailable Metal Concentrations And Total Metal Concentration-Depth Relationship Along The Sediment Profile Within Phuket Bay, Pensiri Akkajit, Danai Tipmanee, Kaimook Jaileak

Applied Environmental Research

Heavy metals in coastal sediments can adversely affect human health and the environment. The distribution and metal bioavailability of Pb and Zn in 21 sediment samples collected from Phuket Bay, Phuket, Thailand using the first-two steps of sequential extraction proposed by the Standards, Measurements and Testing programme (known as BCR) was determined. The results showed that Pb formed weak complexes contributing up to 11.2% to 33% of its total concentration (1.7 to 7.5 mg kg-1) in the first fraction (BCR1), while Zn in the BCR1 fraction ranged from 4.9% to 9.9%. The results suggest that Pb could easily enter the …

Trump’S Legacy: The Long-Term Risks To American Democracy, Michael Vitiello

McGeorge School of Law Scholarly Articles

While President Trump was extreme in his contempt for legal and political norms, his presidency was consistent with the direction in which the Republican Party has moved over the past several decades. Strategies put in place by Trump and other Republicans, along with institutional aspects of our country’s “democracy,” assure the Republican Party’s continued, outsized controll despite Trump’s failure to achieve a second term.

This Article reviews Trump and his Administration’s contempt for political norms, explores the Republican Party’s hard turn to the right, and discusses how the Republicans have been able to hold onto power greater than one would …

The Constitutional Right To “Establish A Home", John G. Sprankling

McGeorge School of Law Scholarly Articles

Everyone needs a home. But exclusionary zoning ordinances in many communities prevent low-income and moderate-income families from securing affordable homes, disproportionately harming people of color. Because these ordinances satisfy the rational basis test, they have been immune from substantive due process attack. This Article provides a new method to challenge the constitutionality of exclusionary zoning.

For decades, the Supreme Court has recognized that the Due Process Clause of the Fourteenth Amendment protects the right to “establish a home.” The Clause was adopted, in part, as a response to the “Black Codes” enacted by southern states in the post-Civil War era …

Amblyomma Quadricavum (Schulze, 1941) (Acari:Ixodidae): First Description Of The Nymphal Stage And Phylogenetic Assessment Of Its Taxonomic Status, Ashleigh V. Riggs

College of Graduate Studies: Theses & Dissertations

The hard tick (Acari: Ixodidae) Amblyomma quadricavum (Schulze, 1941) is a parasite of snakes and is endemic to the Caribbean region. Morphological characters of this species, namely its rudimentary eye structures, have led to debate about its taxonomic status. The species was originally assigned to the genus Aponomma. However, with revisions of the genus Aponomma, and the recent creation of new genera created for some basal former-Aponomma, it has been suggested that perhaps Amblyomma quadricavum might be a close relative of Robertsicus elaphensis, the Trans-Pecos rat snake tick of the southwest United States and New Mexico, another eyeless former-Aponomma species …

À La Carte Cable: A Regulatory Solution To The Misinformation Subsidy, Christopher R. Terry, Eliezer J. Silberberg, Stephen Schmitz, John Stack, Eve Sando

Catholic University Journal of Law and Technology

Although “fake news” is as old as mass media itself, concerns over disinformation have reached a fever pitch in our current media environment. Online media outlets’ heavy reliance on user-generated content has altered the traditional gatekeeping functions and professional standards associated with traditional news organizations. The idea of objectivity-focused informational content has primarily been substituted for a realist acceptance of the power and popularity of opinion-driven “news.” This shift is starkly visible now: mainstream news media outlets knowingly spread hoaxes, conspiracy theories, and the like.

This current state of affairs is not some freak accident. The Supreme Court’s First Amendment …

Representation Learning On Heterogeneous Spatiotemporal Networks, Dakshak Keerthi Chandra

Doctoral Dissertations

“The problem of learning latent representations of heterogeneous networks with spatial and temporal attributes has been gaining traction in recent years, given its myriad of real-world applications. Most systems with applications in the field of transportation, urban economics, medical information, online e-commerce, etc., handle big data that can be structured into Spatiotemporal Heterogeneous Networks (SHNs), thereby making efficient analysis of these networks extremely vital. In recent years, representation learning models have proven to be quite efficient in capturing effective lower-dimensional representations of data. But, capturing efficient representations of SHNs continues to pose a challenge for the following reasons: (i) Spatiotemporal …

Mechanical Properties Of Boride Based Ceramics, Alec Murchie

Doctoral Dissertations

“This research focuses on the elevated mechanical properties of diboride based materials at room and elevated temperatures. These materials include a ZrB₂ ceramic, a ZrB₂-WC-SiC ceramic, and a (Hf,Mo,Nb,Ta,W,Zr)B₂ high entropy boride (HEB). The room temperature flexural strength for the ZrB₂ ceramic was 447 MPa and the fracture toughness was 2.3 MPa·m^1/2. The strength decreased to 196 MPa at 1800°C, and then increased to 360 MPa at 2300°C. The fracture toughness increased to 3.1 MPa·m^1/2 at 2200°C. The strength up to 1800°C was likely controlled by a combination of effects: surface damage …

Peritectic Behavior Detection And Prediction In Fe-C-Si-Mn-Al System, Damilola Balogun

Doctoral Dissertations

"The non-uniformity of shell growth in the continuous casting of peritectic steels constitutes a major barrier to the commercial production of many steel grades such as Advanced high strength steels (AHSS), transformation induced plasticity (TRIP) steels, abrasion-resistant steels, advanced armor plate steels, and many newly proposed steel grades that contain high levels of silicon, manganese, and aluminum.

The shell growth non-uniformity experienced in the continuous casting of peritectic steels results in the formation of defects in the as-cast slab and therefore increases the operating risk from cast aborts and breakouts. The ability to predict and avoid peritectic behavior at the …

Sustainable Face Milling Of Inconel 718 Using Mql And Nanofluids Mql With Vegetable Oil As Base Fluid, Theodore Obumselu Nwoguh

Doctoral Dissertations

"Extreme heat and friction are generated in machining difficult-to-cut metals used in aerospace and nuclear industries leading to poor machinability (high cutting forces, rapid tool wear, shorter tool life, and poor surface integrity). Conventional flood coolant (CEC) used in industry is environmentally unfriendly, hazardous to operators, and unsustainable. These problems motivated this research, which can be mitigated with the use of effective biodegradable cutting fluids, appropriate cutting conditions, and lubrication/cooling strategies. This research provides a sustainable and environmentally friendly replacement to CEC. Firstly, the research characterized three vegetable oils (High Oleic Soybean Oil (HOSO), Low Oleic Soybean Oil (LOSO), and …

Design And Synthesis Of Purine Based Neuroprotectors And Novel Synthetic Methods For The Trifluoromethylation Of Aldehyde Hydrazones, Puspa Aryal

Doctoral Dissertations

"Purine-derived compounds are widely investigated as cyclin-dependent kinase inhibitors that have broad applications in the design of pharmaceuticals for treating diseases, such as diabetes, atherosclerosis, and cancers. Towards the goal of effective AGE-inhibitors, and neuroprotector compounds we have synthesized a series of novel purine-based triazoles and investigated their neuroprotective effects, using SHSY-3Y human neuroblastoma cell line. Through these studies, we have identified purine-based neuroprotector compounds that favorably modulate oxidative stress induced by the Fenton reaction-generated reactive oxygen species (ROS).

The C(sp²−H)-trifluoromethylation of hydrazones would give access to the αtrifluoromethylated hydrazones that can serve as intermediates in the synthesis …

Femininity Reclaiming Chivalry In The Harry Potter Series, Ashley M. Watson

College of Graduate Studies: Theses & Dissertations

This paper focuses on the reclaiming of chivalric values by female characters in the Harry Potter series by comparing them to Arthurian characters. Scholars have extensively compared the narrative of the Knights of the Round Table to the global phenomenon of the Harry Potter series, but in this paper I explore, through a feminist lens, a character comparison of the Harry Potter novels and Sir Thomas Malory’s Le Morte D’Arthur. I will show how female characters in modern literature reclaim chivalry. This is important because it exemplifies a shift in the position of women into a more active role. I …

The ‘Poetry Of Old Roofs’: Edith Wharton And The Art Of Architecture, Elizabeth Emery

Department of World Languages and Cultures Faculty Scholarship and Creative Works

Known internationally for novels such as The House of Mirth (1905) and The Age of Innocence (1921), New York-born Edith Wharton (1862-1937) began her writing career as a poet in 1878 with a self-published volume of Verses. She equated the work of architects and garden designers to that of poets in travel essays from the 1890s and early 1900s, many of which were collected and republished under the titles Italian Villas and their Gardens (1904), Italian Backgrounds (1905), and A Motor-Flight Through France (1908). The present article explores the aesthetics of writing, architecture, and home design in the earliest part …

Disentangling Mtor Complexes Underlying Pten-Loss-Associated Autism Spectrum Disorder, Kamran Tariq

Dartmouth College Ph.D Dissertations

Phosphatase and tensin homolog deleted on chromosome 10 (PTEN) protein is a negative regulator of the AKT serine threonine kinases (Protein Kinase B) in the mechanistic target of rapamycin (mTOR) signaling pathway. Mutations in PTEN are found in patients with autism, epilepsy, or macrocephaly. In mouse models, Pten-loss results in neuronal hypertrophy, hyperexcitability, seizures, and social deficits. The underlying molecular mechanisms of these phenotypes are not well-delineated. I aimed to disentangle the role of the downstream mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2) in orchestrating aberrations in neuronal form and function resulting from Pten-loss. First, we found that …

Communicating Clinic Visit Information To Family Caregivers, Reed Wr Bratches

Dartmouth College Ph.D Dissertations

Statement of the Problem: Information from clinic visits is critical to family caregivers, who are the family members or friends who provide at-home care for their loved ones. However, patient’s clinic visits are infrequently attended by caregivers. While methods exist to communicate information from visits to patients, little is known about the methods used to communicate with caregivers, or their effects on caregiver outcomes. I address this gap in this dissertation through three studies.

Methods: A systematic review was used synthesize the methods used to communicate information to family caregivers and their impact on caregivers. A national survey of family …
