Heavy metal pollution in soil has seriously affected the living environment of human beings Among all heavy metal pollution, cadmium (Cd) is one of the most difficult to migrate pollutants in soil. Therefore, this systematic review includes the remediation techniques of Cd-contaminated groundwater that using. Different remediation techniques, including pump and treat, permeable reactive barrier, adsorption, biosorption, electrochemical, precipitation, ion exchange and bioremediation are reviewed. The advantages and disadvantages of some remediation technologies for cadmium from groundwater are outlined in order to assist the selection of a suitable technology for a groundwater remediation project. Bioremediation is a common remediation strategy …

Effect Of Kelp Gull Harassment On Southern Right Whale Calf Survival: A Long-Term Capture–Recapture Analysis, Macarena Agrelo, Carina F. Marón, Fábio G. Daura-Jorge, Victoria J. Rowntree, Mariano Sironi, Philip S. Hammond, Simon N. Ingram, Florencia O. Vilches, Jon Seger, Paulo C. Simões-Lopes

School of Biological and Marine Sciences

Kelp gulls (Larus dominicanus) commonly feed on the skin and blubber of surfacing southern right whales (SRW, Eubalaena australis) in the near shore waters of Península Valdés (PV), Argentina. Mothers and especially calves respond to gull attacks by changing their swimming speeds, resting postures and overall behaviour. Gull-inflicted wounds per calf have increased markedly since the mid-1990s. Unusually high mortality of young calves occurred locally after 2003, and increasing evidence points to gull harassment as a factor contributing to the excess deaths. After leaving PV, calves undertake a long migration with their mothers to summer feeding areas; their health during …

An Assessment Of The Ecosystem Services Of Marine Zooplankton And The Key Threats To Their Provision, Zara L.R. Botterell, Penelope K. Lindeque, Richard C. Thompson, Nicola J. Beaumont

School of Biological and Marine Sciences

Zooplankton are a key group of organisms at the base of the marine food web and are fundamental to providing a broad range of societal and economic benefits which have previously remained poorly defined. This research addresses this knowledge gap through the provision of a first full assessment of zooplankton ecosystem services and disservices. Anthropogenic stressors such as microplastic pollution, climate change, and fisheries, could negatively affect the marine ecosystem services provided to humans and therefore have a negative impact on human well-being through reduction in food security, livelihoods, income, and good health. Deploying a mixed methodology approach including a …

Artificial Light At Night (Alan) Disrupts Behavioural Patterns Of Reef Corals, M. L. Mardones, J. Lambert, J. Wiedenmann, T. W. Davies, O. Levy, C. D'Angelo

School of Biological and Marine Sciences

Increasing levels of Artificial Light At Night (ALAN) alter the natural diel cycles of organisms at global scale. ALAN constitutes a potential threat to the light-dependent functioning of symbiotic scleractinian corals, the habit-founders of warm, shallow water reefs. Here, we show that ALAN disrupts the natural diel tentacle expansion and contraction behaviour, a key mechanism for prey capture and nutrient acquisition in corals. We exposed four symbiotic scleractinian coral species to different ALAN treatments (0.4–2.5 μmol quanta m−2 s−1). Exposure to ALAN levels of 1.2 μmol quanta m−2 s−1 and above altered the normal tentacle expansion response in diurnal species …

Marine Spatial Planning (MSP) has become a priority for many states wanting to develop national blue economy plans and meet international obligations in response to the increasing cumulative impacts of human activities and climate change. In areas beyond national jurisdiction (ABNJ), MSP is proposed as part of a package of solutions for multi-sectoral management at the ocean basin scale. To facilitate planning, maps showing the spatial distribution of marine biological diversity are required. In areas lacking data, like the South Atlantic, environmental proxies can be used to predict these distributions. We undertook broad-scale benthic habitat classification of the South Atlantic, …

Ordered Liberty After Dobbs, Linda C. Mcclain, James E. Fleming

Faculty Scholarship

This Essay explores the implications of Dobbs v. Jackson Women’s Health Organization for the future of substantive due process (SDP) liberties protecting personal autonomy, bodily integrity, familial relationships (including marriage), sexuality, and reproduction. We situate Dobbs in the context of prior battles on the Supreme Court over the proper interpretive approach to deciding what basic liberties the Due Process Clause (DPC) protects. As a framing device, we refer to two competing approaches as “the party of [Justice] Harlan or Casey” versus “the party of Glucksberg.” In Dobbs, the dissent co-authored by Justices Breyer, Sotomayor, and Kagan represents the party of …

Nonconsensual Family Obligations, Emily Stolzenberg

Faculty Publications

Even as the pandemic has both highlighted and compounded the challenges many U.S. families face in meeting their members’ basic needs, efforts to expand public subsidies for caretaking have gained little traction. Scholars have identified many historical and practical reasons for Americans’ entrenched skepticism toward the welfare state. Ideas matter, too, and this Article uncovers and critiques one that works to limit collective financial responsibility for families: the conviction that family support obligations must be legitimated through consent.

In family law, as in liberal political theory, consent works to reconcile state regulation with individual freedom. But because consent is a …

Nature-Based Education: Expanding The Walls Of The Classroom, Halle Louise Kilburg

Honors Program Theses

Are the current practices of education one that best benefits a student? Every day, millions of children go to school. While there is a wide variety of what this experience may look like, there are common factors, such as sterile classroom environments, canned experiences, and dry lectures that often contribute to leaving students feeling burnt out, exhausted, and unmotivated. The purpose of this study was to explore how various schools use Nature-Based education to run their programs and the impact of this approach on students and teachers. For this study, four educators from three various programs were interviewed and asked …

Design, Evolution, And Evaluation Of A General Chemistry-Bridging Course, Scott A. Reid

Chemistry Faculty Research and Publications

General chemistry I/II courses are important gateway courses for a variety of STEM majors, as poor performance in these courses is often associated with lower rates of student success and retention. Much research has explored preparatory or remedial strategies to improve student outcomes. In this article, we report a different approach, which involved the development of a bridging or intervention course designed to capture students who are not or have not succeeded in general chemistry I and prepare them to retake the course in the following semester or summer. The course was initially developed as an eight-week module in the …

Measuring How Kinetochore-Microtubule Detachment Contributes To Chromosome Movement And The Correction Of Attachment Errors, Melissa K. Parks

Dartmouth College Ph.D Dissertations

The goal of mitosis is to achieve faithful chromosome segregation; ensuring that the daughter cells inherit equal numbers of chromosomes. This is vital to cell health and viability and if mis-regulated can result in birth defects and disease such as cancer. There are many intricately regulated processes that occur throughout mitosis to achieve proper chromosome segregation, and one such example is the dynamic attachments formed between cytoskeletal structures, known as microtubules, and chromosomes, the carriers of genetic material. These attachments occur at structures called kinetochores, and the microtubules attached here are referred to as kinetochore-microtubules (k-MTs). These k-MTs are inherently …

Identifying Spatial Heterogeneity In And Potential Biological Consequences Of River Thermal Environments, Keith Jeffrey Fritschie

Dartmouth College Ph.D Dissertations

Temperature is a nearly ubiquitous driver of ecological and evolutionary processes, especially for organisms whose body temperature changes with the environment. The overarching biological importance of environmental temperature and increased availability of temperature datasets have led to its inclusion in spatially continuous models of species’ performance, abundance, and distribution. However, variation in both environmental temperature and animal behavior at finer scales than captured by these models may reduce the accuracy of their scientific conclusions and conservation recommendations. Here I contribute to an improved understanding of thermal variability in river systems and its potential biological consequences for an iconic coldwater species, …

Machine Learning For Electronic And Atomistic Simulations, Jun Yang

Dartmouth College Ph.D Dissertations

The demand for accurate and efficient atomistic simulations and electronic structure calculations in materials science and quantum chemistry has motivated the development of novel computational methodologies. The rapid evolution of machine learning has brought new techniques for advancing the accuracy, efficiency, and predictive power of atomistic simulations and electronic structure calculations.

In this thesis, we explore the symmetry requirements and physics intuitions needed for developing machine-learning interatomic potentials, which are the most critical component in atomistic simulations. Specifically, we introduce a novel physics-inspired graph neural network interatomic potential that enables accurate and efficient atomistic simulations of complex materials. The machine …

Airborne Sound And Substrate-Borne Vibration In Orthopteran Communication, Ciara E. Kernan

Dartmouth College Ph.D Dissertations

The challenge of attracting and locating potential mates has driven the evolution of diverse mate-finding signaling systems. These systems can be complex, with multiple signals or signal components spread across different sensory modalities. When multiple modalities are combined in one communication system, features of each can be important to individual fitness; over evolutionary time, these can shape investment in different parts of a signal repertoire. One group of animals that commonly uses multiple signal modalities is Orthoptera. Cricket and katydid species within this order often produce airborne sound calls to advertise to potential mates. Many also produce substrate-borne vibrational signals. …

Accelerated Forgetting In People With Epilepsy: Pathologic Memory Loss, Its Neural Basis, And Potential Therapies, Sarah Ashley Steimel Phd

Dartmouth College Ph.D Dissertations

While forgetting is vital to human functioning, delineating between normative and disordered forgetting can become incredibly complex. This thesis characterizes a pathologic form of forgetting in epilepsy, identifies a neural basis, and investigates the potential of stimulation as a therapeutic tool. Chapter 2 presents a behavioral characterization of the time course of Accelerated Long-Term Forgetting (ALF) in people with epilepsy (PWE). This chapter shows evidence of ALF on a shorter time scale than previous studies, with a differential impact on recall and recognition. Chapter 3 builds upon the work in Chapter 2 by extending ALF time points and investigating the …

Advanced Tools For Time-Resolved Imaging Of Tissue Metabolism, Arthur Petusseau

Dartmouth College Ph.D Dissertations

Medical imaging is a crucial tool in diagnosing and treating diseases, and by far the most common set of tools used for point-of-care guidance between a physician and patient are optical devices. For example, visible light imaging has unique applications in endoscopy, dermatology, microscopy, and this range of devices utilize a wide range of optical signals for sensing the tissue. Fluorescence imaging has become a niche but growing methodology in medical diagnostics and treatment because of its simplicity and the ability to integrate reporter molecules, that can reveal detailed information about cellular structures, metabolism, signaling, and other biomolecular features of …

Inhibition Of Cal Pdz Domain Via Non-Canonical And Allosteric Interactions Reveals New Targeting Sites And Strategies, Nicholas Paul Gill

Dartmouth College Ph.D Dissertations

Significant therapeutic achievements have been made in the past decade towards increasing the pool of correctly folded F508del-CFTR and enhancing its activity at the apical membrane. Despite this success, there are still no FDA-approved therapeutics that directly target the post-endocytic stability of F508del-CFTR. Upon internalization, it is rapidly degraded through binding the CFTR-associated ligand (CAL) PDZ domain (CALP), which triggers its degradation in the lysosome. Our group and others have shown that inhibiting CAL increases the half-life of functional F508del-CFTR at the cell‑membrane and significantly enhances ion transport, suggesting that ‘stabilizer’ compounds, especially in conjunction with current CF therapeutics, would …

The Gender Of Gideon, Kathryn A. Sabbeth, Jessica Steinberg

Faculty Publications

This Article makes a simple claim that has been overlooked for decades and yet has enormous theoretical and practical significance: the constitutional guarantee of counsel adopted by the U.S. Supreme Court in Gideon v. Wainwright accrues largely to the benefit of men. In this Article, we present original data analysis demonstrating that millions of women face compulsory and highly punitive encounters with the justice system but do so largely in the civil courts, where no right to counsel attaches. The demographic picture that emerges is one in which the right to counsel skews heavily against women’s interests. As this Article …

The Nightmare Of Dream Advertising, Dustin Marlan

Faculty Publications

Advertisers are attempting to market to us while we dream. This is not science fiction, but rather a troubling new reality. Using a technique dubbed “targeted dream incubation” (TDI), companies have begun inserting commercial messages into people’s dreams. Roughly, TDI works by: (1) creating an association during waking life using sensory cues (for example, a pairing of sounds, visuals, or scents); and (2) as the subject is drifting off to sleep, the association is again introduced with the goal of triggering related dreams with related subject matter. Based on a 2021 American Marketing Association survey, 77 percent of 400 companies …

A Synthesis Of The Science And Law Relating To Eyewitness Misidentifications And Recommendations For How Police And Courts Can Reduce Wrongful Convictions Based On Them, Henry F. Fradella

Seattle University Law Review

The empirical literature on perception and memory consistently demonstrates the pitfalls of eyewitness identifications. Exoneration data lend external validity to these studies. With the goal of informing law enforcement officers, prosecutors, criminal defense attorneys, judges, and judicial law clerks about what they can do to reduce wrongful convictions based on misidentifications, this Article presents a synthesis of the scientific knowledge relevant to how perception and memory affect the (un)reliability of eyewitness identifications. The Article situates that body of knowledge within the context of leading case law. The Article then summarizes the most current recommendations for how law enforcement personnel should—and …

Adapting Grief And Bereavement-Focused Cognitive Behavioral Therapy For Chinese-Identifying Individuals In America: A Cultural Analysis, Ian Tsang

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Anti-Asian hate as well as shifting circumstances brought on by current events all around the world highlight the increased need for mental health support and services in an ever-growing Chinese population in the United States, particularly in regard to grief work. Additionally, Chinese Americans demonstrate a disproportionate and lower utilization of mental health services, especially in comparison to the general population in the country. This paper discusses the various factors contributing to this phenomenon before presenting recommendations for culturally adapting evidence-based approaches to grieving individuals in the target population. More specifically, a cultural analysis consisting of topics such as Chinese …

Rethinking Innovation At Fda, Rachel Sachs, W. Nicholson Price Ii, Patricia J. Zettler

Scholarship@WashULaw

In several controversial drug approval decisions in recent years, the Food & Drug Administration (FDA) has publicly justified its decision partly on the ground that approving the drugs in question would support innovation in those fields going forward. To some observers, these arguments were surprising, as the agency’s determination whether a drug is “safe” and “effective” does not seem to depend on whether its approval also supports innovation. But FDA’s use of these innovation arguments in drug approval decisions is just one example of the ways in which the agency has come to make many innovation-related judgments as part of …

Heterologous Mrna-Protein Vaccination With Tc24 Induces A Robust Cellular Immune Response Against Trypanosoma Cruzi, Characterized By An Increased Level Of Polyfunctional Cd8+ T-Cells, Cristina Poveda, Ana Carolina Leão, Chiara Mancino, Francesca Taraballi, Yi-Lin Chen, Rakesh Adhikari, Maria Jose Villar, Rakhi Kundu, Duc M Nguyen, Leroy Versteeg, Ulrich Strych, Peter J Hotez, Maria Elena Bottazzi, Jeroen Pollet, Kathryn M Jones

Tc24 is a Trypanosoma cruzi-derived flagellar protein that, when formulated with a TLR-4 agonist adjuvant, induces a balanced immune response in mice, elevating IgG2a antibody titers and IFN-γ levels. Furthermore, vaccination with the recombinant Tc24 protein can reduce parasite levels and improve survival during acute infection. Although some mRNA vaccines have been proven to elicit a stronger immune response than some protein vaccines, they have not been used against T. cruzi. This work evaluates the immunogenicity of a heterologous prime/boost vaccination regimen using protein and mRNA-based Tc24 vaccines. Mice (C57BL/6) were vaccinated twice subcutaneously, three weeks apart, with …

Neprilysin is an endopeptidase that cleaves a variety of peptides such as natriuretic peptides, bradykinin, adrenomedullin, substance P, angiotensin I and II, and endothelin. It has a broad role in cardiovascular, renal, pulmonary, gastrointestinal, endocrine, and neurologic functions. The combined angiotensin receptor and neprilysin inhibitor (ARNi) has been developed with an intent to increase vasodilatory natriuretic peptides and prevent counterregulatory activation …

Evaluating The Proportion Of Isolated Cases Among A Spectrum Of Birth Defects In A Population-Based Registry, Peter H Langlois, Lisa Marengo, Philip J Lupo, Margaret Drummond-Borg, A J Agopian, Wendy N Nembhard, Mark A Canfield

Faculty, Staff and Students Publications

INTRODUCTION: Because the etiology and outcomes of birth defects may differ by the presence vs. absence of co-occurring anomalies, epidemiologic studies often attempt to classify cases into isolated versus non-isolated groupings. This report describes a computer algorithm for such classification and presents results using data from the Texas Birth Defects Registry (TBDR).

METHODS: Each of the 1,041 birth defects coded by the TBDR was classified as chromosomal, syndromic, minor, or "needs review" by a group of three clinical geneticists. A SAS program applied those classifications to each birth defect in a case (child/fetus), and then hierarchically combined them to obtain …

Center for Medical Ethics and Health Policy Staff Publications

Psychedelic therapy is, arguably, the next frontier in psychiatry. It offers a radical alternative to longstanding, mainstays of treatment, while exciting a paradigm shift in translational science and drug discovery. There is particular interest in 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT)—a serotonergic psychedelic—as a novel, fast-acting therapeutic. Yet, few studies have directly examined 5-MeO-DMT for trauma- or stress-related psychopathology, including post-traumatic stress disorder (PTSD). Herein, we present the first longitudinal case study on 5-MeO-DMT for chronic refractory PTSD, in a 23-year-old female. A single dose of vaporized bufotoxin of the Sonoran Desert Toad (Incilius alvarius), containing an estimated 10−15 mg …
