Food Waste In The United States: Issues, Ethics, And Solutions, Patrick Erickson

Honors College Theses

One-third of all food produced for human consumption is lost or wasted globally. In North America and Europe, 280-300 kg of food is wasted per capita each year, with more than 40% of the losses occurring at the retail and consumer level. In this paper, I compare the amount of food wasted in the United States to the amounts wasted by different societies around the world, and discuss the reasons for the food waste, and the consequences that the waste has on our society, in terms of resource consumption and production of pollution. The pragmatic philosophy of Richard Rorty states …

Water fluoridation has been one of many significant methods of incorporating fluoride into the oral cavity, enhancing …

The Interommatidial Bristle Variability Of Diptera, Kimberly Palmer

Honors College Theses

Insects of the order Diptera are a popular biological model for understanding morphological trait evolution. One area of particular interest is the development of the compound eyes. While the development of ommatidia and photoreceptors has been thoroughly studied in this case, little attention has been paid to the interommatidial bristles (IOBs) present on the eyes of some dipteran families. A preliminary survey suggested that these bristles exhibit high variability among IOB families on multiple taxonomic levels and are not uniformly present or absent in any suborder of the Diptera. To confirm this observation, I conducted a literature search to …

The Loaded Squat, Gianluca Scerri

Honors College Theses

Although torque on the knee joints and it’s various supporting structures has been shown to increase when an individual allows for their knees to track farther over their toes, this action alone should not stop an individual from performing a squat, because of a possible fear of “damaging” their knees. Instead, the individual should take three main aspects of proper squat technique into consideration, in order to maximize their squat potential using a barbell. These include: the force being placed upon their lumbar spine and the stability of the trunk, proper ankle dorsiflexion, and adequate knee flexion.

This thesis will …

Racial Microaggressions On An Online Anonymous Platform, Navneesh Pandher

Honors College Theses

In sociology there has been an increase amount of scholarly attention devoted to the microaggressions as a theoretical construct. Efforts have been devoted towards understanding the themes, track the progress of the term to its modern day use, the different forms that microaggressions take, and the consequences to individuals that suffer in these encounters. Typically, microaggression research is centered around interviews with minorities but there is minimal investigation into the presentation of these encounters on online platforms where users can maintain an anonymous identity. A content analysis with 5 codes was conducted of a blog that is open to anonymous …

Remote Preconditioning: Evaluating The Efficacy Of Cardioprotection In Type-2 Diabetes And Exploring The Mechanistic Role Of Exosomes, Joseph Michael Wider

Wayne State University Dissertations

Remote preconditioning is a promising and robust treatment for myocardial

ischemia/reperfusion injury that evokes cardioprotection through endogenous neural

and/or humoral signaling. A recent study has reported that protective signaling is

mediated by exosomes through the circulation; however this concept is supported by

limited and inconsistent evidence. Despite overwhelming success in preclinical studies,

the efficacy of remote preconditioning in human studies is inconclusive. Importantly, the

majority of remote preconditioning studies use healthy animal models despite growing

evidence that comorbidities, such as type-2 diabetes, may negatively influence

outcomes. Nonetheless, the efficacy of remote preconditioning in the setting of type-2

diabetes has not …

This dissertation explores feminism in the Michigan Republican Party from the late 1960s until the early 1980s through the activism of seven women. These women, Republicans before they were feminists, believed in the efficacy of party politics to bring about change. Therefore, it was only natural that once they became feminists they turned to the political system to effectuate gender equality. They sought to bring feminism into …

Effect Of Endoplasmic Reticulum Stress On Vascular Smooth Muscle Cells And Its Regulation Of Sm22Α, Neeraja Priyanka Annam

Wayne State University Dissertations

Background: The vascular smooth muscle cells(VSMC) possess the ability to differentiate into a synthetic phenotype in response to stress. This phenotypic modulation may be accompanied by inflammatory or osteogenic response in chronic stress. The synthetic state is characterized by low levels of contractile markers unlike the differentiated state.

Hypothesis: Endoplasmic reticulum (ER) stress causes phenotypic modulation in VSMCs leading to apoptosis. Many transcription factors induced by ER stress contribute to the downregulation of Sm22α. Perturbation in cytoskeletal dynamics exacerbates the ER stress response.

Methods: Ex-vivo culture was used to establish importance of Sm22 in ER stress. In vitro analysis was …

On The Design Of Low-Complexity High-Speed Arithmetic Circuits In Quantum-Dot Cellular Automata Nanotechnology, Amjad Almatrood

Wayne State University Dissertations

For the last four decades, the implementation of very large-scale integrated systems has largely based on complementary metal-oxide semiconductor (CMOS) technology. However, this technology has reached its physical limitations. Emerging nanoscale technologies such as quantum-dot cellular automata (QCA), single electron tunneling (SET), and tunneling phase logic (TPL) are major candidate for possible replacements of CMOS. These nanotechnologies use majority and/or minority logic and inverters as circuit primitives. In this dissertation, a comprehensive methodology for majority/minority logic networks synthesis is developed. This method is capable of processing any arbitrary multi-output Boolean function to nd its equivalent optimal majority logic network targeting …

Analyzing The Regulation, Stability And Functional Differences Between Sin3 Isoforms In Drosophila, Ashlesha Chaubal

Wayne State University Dissertations

SIN3 is a master transcriptional regulator, conserved from yeast to mammals, that acts as a scaffold protein for a histone modifying complex. In Drosophila, a single Sin3A gene is alternatively spliced to produce distinct SIN3 isoforms; SIN3 220, SIN3 190 and SIN3 187, that differ only at their C-terminus. These isoforms are differentially expressed during development. We have shown that there is an interplay between the predominant isoforms of SIN3, SIN3 220 and SIN3 187, that possibly regulates the overall level of SIN3 in the cell. Exogenous expression of SIN3 187 reduces the level of transcript and accelerates the proteasomal …

Development Of A Programmed Electrospun Three Dimensional (3d) Nanofiber Collecter And It’S Application To Orthopedic Implant Coatings, Liang Chen

Wayne State University Dissertations

Orthopedic implants might not directly unite with bones especially in compromised patients even if they have been appropriately fixed. The lack of early osseointegration would lead to the failure of the orthopedic implant. A “bone-like” implant surface is urgently needed to accelerate osseointegration. Electrospun nanofiber (NF) is a promising implant coating due to its highly porous nanoscale structure. It mimics the collagen I nanofibrous network of bone tissue; meanwhile it has been widely used as a drug delivery device. However, its compact and dense structure is not ideal for cell growth. Our strategy was to develop a functional three-dimensional (3D) …

How To Understand The Debate Over Presentism And Eternalism, Travis Matthew Figg

Wayne State University Dissertations

Presentism is the view that, with the possible exception of things outside of time, everything that exists, exists at the present time. It is contrasted with eternalism, the view that everything which ever did exist or ever will exist, exists. Some philosophers argue that presentism and eternalism are not really substantive, opposed metaphysical theses. I consider some attempts in the literature to rebut this skeptical position, and argue that they are unsatisfactory. Then I make my own case for the conclusion that presentism and eternalism are substantive metaphysical theses by drawing a distinction between two ways of talking about what …

Functional Analysis Of Rad6 In Brca1 Wild Type And Brca1 Mutant Triple Negative Breast Cancer Drug Response, Brittany Haynes

Wayne State University Dissertations

TNBCs account for 15-20% of all breast and are unsuitable for common targeted therapies as they lack expression of estrogen, progesterone, and Her2/neu receptors. Cisplatin, a DNA damaging agent, is currently under clinical investigation for treatment of TNBCs and paclitaxel, a mitotic spindle poison, is a first-line treatment option for this disease. While both agents elicit therapeutic benefit BRCA1 mutation status, toxicity, and resistance are limiting factors. Rad6 functions as an E2 ubiquitin conjugating protein and its enzymatic activity is critical for its cellular function. Rad6 is known to play a critical role in the translesion synthesis (TLS) damage response …

Evaluation Of Earth-Abundant Monometallic And Bimetallic Complexes For Catalytic Water Splitting, Kenneth Kwame Kpogo

Wayne State University Dissertations

The development of affordable water splitting catalysts from Earth-abundant transition metal ions such as Co and Mn is of immense scientific interest. Aiming to develop an efficient water splitting catalyst, a Co(II) complex featuring an asymmetric, pentadentate quinolyl-bispyridine ligand with a phenylenediamine backbone was synthesized and characterized by spectroscopic, spectrometric, and X-ray analysis. The Co ion was selected because of its ability to undergo redox conversions from 3d5 CoIV through 3d8 CoI thereby making it a suitable catalyst that can withstand harsh structural and electronic changes during catalysis. The electrocatalytic water reduction activity of the catalyst at neutral pH gave …

The aim of this dissertation is to unveil the mechanisms underlying the carcinogenic activities of environmental arsenic. The biological functions of arsenic had been studied for decades. However, there are still many questions that remain to be fully answered, such as whether and how arsenic contributes to the epigenetic regulations and migration or metastasis control of the cancer cells. In this regard, we focused our attention on both histone modifications and miRNA regulations in the arsenic-induced malignant transformation of the cells, …

Study Of Periodical Flow Heat Transfer In An Internal Combustion Engine, Xi Luo

Wayne State University Dissertations

In-cylinder heat transfer is one of the most critical physical behaviors which has a direct influence on engine out emission and thermal efficiency for IC engine. In-cylinder wall temperature has to be precisely controlled to achieve high efficiency and low emission. However, this cannot be done without knowing gas-to-wall heat flux. This study reports on the development of a technique suitable for engine in-cylinder surface temperature measurement, as the traditional method is “hard to reach.” A laser induced phosphorescence technique was used to study in-cylinder wall temperature effects on engine out unburned hydrocarbons during the engine transitional period (warm up). …

By

THOMAS MCFALL

December 2017

Advisor: Dr. Manohar Ratnam

Major: Cancer Biology

Degree: Doctor of Philosophy

Over 20% of breast cancer cases present with distal metastasis and they are predominantly of luminal subtypes. As luminal breast cancer is relatively indolent, it is believed that progression to metastasis must occur over many years, generally well into post-menopausal years. Unfortunately, very little is known about the mechanisms by which these hormone receptor positive tumors metastasize, likely in part due to their slow metastatic rates in animal model systems as …

A Narrative Study Of Chaldean Refugees And The Myth Of Return: From Chaldean Babylon To The New World, Joseph James Byle

Wayne State University Dissertations

With the removal of Saddam following the 2003 U.S. invasion of Iraq, life for all Iraqis changed for the worse, especially for minorities such as Christians, including Chaldeans. Considering the powerful push factors that have compelled Chaldean Refugees in the Detroit area to leave Iraq, the idea of returning to the homeland would seem like a remote possibility, however, these Chaldeans present an intriguing case, due to the fact that they are among the indigenous people in Iraq. Do their deep rooted ties to the homeland contribute to a desire to return? This research examines this possibility through an in-depth …

Development Of Tools For Phosphosite-Specific Kinase Identification And Discovery Of Phosphatase Substrates, Pavithra Maheshani Dedigama Arachchige

Wayne State University Dissertations

Phosphorylation is a ubiquitous post translational modification implicated in many diseases, such as cancer. The phosphorylation status of cellular proteins is regulated by the activity of kinases and phosphatases. The biological significance of many phosphorylation events remain unknown because the methods to determine which kinase or phosphatase is responsible for phosphorylation are limited. Previously, we established kinase-catalyzed labeling where kinases accept γ-modified ATP analogs, such as ATP-arylazide and ATP-biotin, to label phosphoproteins. To study substrates of kinases and phosphatases, here we developed two new methods using kinase-catalyzed labeling. As one application, we developed K-CLASP (Kinase-catalyzed CrossLinking And Streptavdin Purification) to …

Identifying The Function Of The Calpain Small Subunit In The Mechanics Of Cell Migration, Bingqing Hao

Wayne State University Dissertations

Cell migration plays a vital role in many physiological events including: morphogenesis, wound healing, and immune response. Dysfunctional cell migration results in multiple disease states including chronic inflammation, vascular disease, and tumor metastasis, to name a few. Progress in understanding the mechanism of cell migration had been slow until the turn of the century when rapid technological advances in microscopy and omics burst to the forefront. These advances led to the realization that physical factors (dimensions, fluid shear stress, hydrostatic pressure, compression stress, environmental stiffness, and topography) have profound effects on cell migration. This study of cell mechanics has expanded …

Automated Refinement Of Hierarchical Object Graphs, Mohammad Ebrahim Khalaj

Wayne State University Dissertations

Object graphs help explain the runtime structure of a system. To make object graphs convey design intent, one insight is to use

abstraction by hierarchy, i.e., to show objects that are implementation details as children of architecturally-relevant objects from the application domain. But additional information is needed to express this object hierarchy, using ownership type qualifiers in the code. Adding qualifiers after the fact involves manual overhead, and requires developers to switch between adding qualifiers in the code and looking at abstract object graphs to understand the object structures that the qualifiers describe. We propose an approach where developers express …

Exploring The Physics Of Proteins At Molecular Level By Neutron And X-Ray Scattering, Utsab Raj Shrestha

Wayne State University Dissertations

The protein structures revealed by the crystallographic studies have provided the valuable information over the years regarding their biological functions. However, such snapshots of protein fluctuations averaged over time may not be enough to fully capture the underlying biological phenomena. A deeper understanding of the protein dynamics is crucial for elucidating the structural pathways or the transition mechanism from the initial state to the final state necessary for regulating the physical and chemical processes. Hence, the biological activities and functions are mainly governed by the protein conformational dynamics. However, the direct correlation of a wide range of protein dynamics to …
