Basal Autophagy Promotes Accurate Chromosome Segregation In Drosophila Oocytes And Declines During Oocyte Aging, Diana C. Hilpert

Dartmouth College Ph.D Dissertations

The frequency of trisomic pregnancies exponentially increases with advanced maternal age, a phenomenon known as the maternal age effect. The majority of these aneuploid pregnancies arise from meiotic segregation errors in the oocyte and premature loss of sister chromatid cohesion is a contributing factor. However, the mechanisms that lead to premature cohesion loss during oocyte aging are not fully understood.

Using Drosophila melanogaster as a model organism, work described in this dissertation demonstrates that basal levels of autophagy, a degradation process for damaged organelles and protein aggregates, are required during meiotic prophase for arm cohesion maintenance and accurate meiotic segregation …

The Rose That Grew From Concrete: Exploring The Romantic Experiences Of Black Men With Histories Of Childhood Sexual Abuse, Tatyana Nichelle Smith

Dissertations

Contemporary research typically characterizes Black heterosexual relationships by dismal marriage and divorce rates, largely ignoring the reality of how Black men develop attachments with their romantic partners and therefore continuing to perpetuate deficit perspectives of Black men (e.g., the cause of conflictual romantic relationships and “broken” Black families). What may be less understood about these relationships is the influence of childhood trauma, such as childhood sexual abuse, and Black men’s experiences of gender role conflict. Research shows that Black men’s experiences of childhood sexual abuse and socialization about masculinity have important implications for how they come to view themselves and …

Third-Party Funding Of Patent Litigation: Problems And Solutions, Korok Ray, Adam Olson

Utah Law Review

This Article documents the rise of third-party funding in patent litigation. We track funding sources for patent lawsuits in the United States from 2002 to 2021, which show an increase in cases and percentage funded by third parties. While we cannot say third-party funding increased patent litigation, we can observe the correlation. The use of the champerty doctrine by patent trolls distorts the marketplace and causes frivolous litigation.

The secondary patent market created a robust litigation market in which non-practicing entities (NPEs) can buy from innovators and sue defendants. Capital investments bet on litigation, hoping for a return without interest …

A diagnostic rubric is required to distinguish between limbic-predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) and frontotemporal lobar degeneration with TDP-43 inclusions (FTLD-TDP). In LATE-NC Stage 3, TDP-43 proteinopathy is present in the middle frontal gyrus (MFG), thus posing a potential diagnostic challenge in differentiating these severe LATE-NC cases from FTLD-TDP. LATE-NC Stage 3 cases and other TDP-43 proteinopathies were analyzed from the University of Kentucky (total n = 514 with TDP-43 pathology assessed), The 90+ Study at the University of California Irvine (n = 458), and the Mayo Clinic (n = 5067) brain banks. Digital pathology was used to …

Uv Vessel Hoist Scope Of Work, Quinn J. Horak, Harvey Perkins, Andrew A. Osborn, Mikayla H. Nieman

Mechanical Engineering

The San Luis Obispo Wastewater Treatment Plant uses ultraviolet (UV) tubes to purify water. These tubes are cleaned by an internal wiping mechanism that must be removed for servicing and replacing damaged tubes. Currently, this is accomplished by using an engine hoist, but this method requires a large amount of effort and is not safe. Technicians have requested a new method of lifting wiper mechanisms that is safer, faster, and easier to use than their current method.

To solve this problem, we have developed a design that consists of a custom gantry crane with a hoist on a trolley. The …

Trailer Transport System For Multi-Ton Bins, Joanna Lizbeth Bendy, Kevin Matthew Creel, Annelise Vaara Cuneo, Hugo Alonso Valdez

Brush Seal Cycling Test Rig, Angelo J. Reis, Neil M. Bedagkar, Max A. Soury, Eoin K. Lenham

Mechanical Engineering

To prevent backflow from the high pressure compressor stages of their gas turbines to lower pressure regions, Solar Turbines utilizes brush seals along their driveshafts. Due to manufacturing limitations, no shaft is perfectly symmetric about its rotating axis, leading to orbiting that creates asymmetric friction on the shaft through rubbing. With this biased application of friction comes a hotspot on one side of the shaft, causing bowing of the shaft and cascading into an amplified vibrational response. Our goal is to gather data on this phenomenon and offer a potential solution.

Anything No Longer Goes: How The Eleventh Circuit Has Settled On One Standard To Determine Deliberate-Indifference Claims, Sarah Beth Scarborough

Mercer Law Review

Deliberate indifference to the medical care of a loved one, or oneself, rightly causes outrage. When such an occurrence takes place behind prison walls, inmates or loved ones on their behalf, file a deliberate indifference claim under 42 U.S.C. § 1983,and they allege a violation of their Eighth Amendment right to be free of cruel and unusual punishment. However, the test for deliberate indifference has been misconstrued and misapplied for decades within the United States Court of Appeals for the Eleventh Circuit. Such a malleable test leads to different standards of proof for a plaintiff to meet, and confusion among …

Repugnant Verdicts For $1000: Navigating The Intersection Of Double Jeopardy And Conflicting Verdicts In Mcelrath V. Georgia, Talia Levine

Mercer Law Review

“No man is to be brought into jeopardy of his life, more than once, for the same offense.” This ancient maxim, preserved in the Double Jeopardy Clause of the Fifth Amendment, is a hallmark of the American justice system. The Double Jeopardy Clause gives a criminal defendant the constitutional right not to be tried again for the same offense after being acquitted. This guarantee stands as “[p]erhaps the most fundamental rule in the history of double jeopardy jurisprudence.”

The Supreme Court of the United States has repeatedly upheld these principles; by refusing to allow retrial following an acquittal, the Court …
