ABSTRACT

ANALYSIS OF MICROMIXERS TO MINIMIZE SCALING EFFECTS ON REVERSE OSMOSIS MEMBRANES

by

Jeremy Walker

December 2018

Advisor: Dr. Shawn McElmurry

Major: Civil Engineering

Degree: Doctor of Philosophy

Structural elements, typically mesh spacers, are required between membrane leaves in spiral

wound elements to ensure flow through reverse osmosis (RO) modules. The standard diamond-shaped

mesh spacer results in non-ideal hydrodynamics that can lead to fouling, which ultimately reduces the

flux of water through the membrane and the operational life of the unit. Additionally, traditional mesh

feed spacers do not allow for reverse flow cleaning due to obstructed flow paths and, once …

Objective: The objective of this study was to assess the effectiveness of a routine multivitamin supplementation program for adults living with HIV in Tanzania.

Design: We conducted a retrospective cohort study of 67,707 adults enrolled in the Dar es Salaam HIV care and treatment program during 2004-2012.

Methods: The Dar es Salaam HIV care and treatment program intended to provide all adult patients with multivitamin supplements (vitamins B-complex, C, and E) free of charge; however, intermittent stockouts and other implementation issues did not afford universal coverage. We use Cox proportional hazard models to assess the time-varying association of multivitamin supplementation …

West Virginia ranks first in the nation for opioid overdose deaths, with an estimated 60,000 people needing treatment for Opioid Use Disorder (OUD) and approximately 280 physicians certified to provide MAT. Semi-structured individual interviews lasting one hour were the primary source of information …

The Life History Of Faxonius Rusticus (Girard, 1852) In Sunfish Creek, Monroe County, Ohio, Kyle Mcgill

Theses, Dissertations and Capstones

Crayfish are among the most imperiled faunal groups globally. The continued spread of invasive species is a major impact to crayfish. Invasive species, much like the native species, are often understudied. As declines continue, invasive species spread, and new species are discovered; additional life history studies are as important as ever for crayfish conservation. Life history data was collected for rusty crayfish (Faxonius rusticus) from October 2017 to September 2018 in Sunfish Creek, Monroe County, Ohio. Faxonius rusticus are native to the Ohio River drainage around Cincinnati, Ohio but have extensively expanded their range over the past 30 years. Sunfish …

Family Structure And Family Management Practices: Associations With Positive Aspects Of Youth Well-Being, Jonathon J. Beckmeyer, Luke T. Russell

Faculty Publications - Family and Consumer Sciences

Using data from a national sample of 15-year olds (N = 681) we tested if four family management practices (parental knowledge, behavioral control, parental academic involvement, and unsupervised time with peers) differed between family structures (i.e., biological-parent, stepfather, or single-mother family). We then identified the family management practices associated with positive youth well-being (psychosocial maturity, positive friendship networks, and school bonding) within each family structure. Parental knowledge, academic involvement, and behavioral control were greater in biological-parent than single-mother families. Stepfather families only differed from biological-parent and single-mother families on parental academic involvement. Although family management practices were associated with youth …

Multiple Signaling Functions Of Song In A Polymorphic Species With Alternative Reproductive Strategies, M. L. Grunst, A. S. Grunst, Vincent A. Formica, R. A. Gonser, E. M. Tuttle

Biology Faculty Works

Vocal traits can be sexually selected to reflect male quality, but may also evolve to serve additional signaling functions. We used a long-term dataset to examine the signaling potential of song in dimorphic white-throated sparrows (Zonotrichia albicollis). We investigated whether song conveys multifaceted information about the vocalizing individual, including fitness, species identity, individual identity, and morph. We also evaluated whether song traits correlate differently with fitness in the two morphs, as the more promiscuous strategy of white, relative to tan, morph males might impose stronger sexual selection. Males with high song rates achieved higher lifetime reproductive success, and this pattern …

Using Regular Languages To Explore The Representational Capacity Of Recurrent Neural Architectures, Abhijit Mahalunkar, John D. Kelleher

Conference papers

The presence of Long Distance Dependencies (LDDs) in sequential data poses significant challenges for computational models. Various recurrent neural architectures have been designed to mitigate this issue. In order to test these state-of-the-art architectures, there is growing need for rich benchmarking datasets. However, one of the drawbacks of existing datasets is the lack of experimental control with regards to the presence and/or degree of LDDs. This lack of control limits the analysis of model performance in relation to the specific challenge posed by LDDs. One way to address this is to use synthetic data having the properties of subregular languages. …

S-Plot2: Rapid Visual And Statistical Analysis Of Genomic Sequences, Laurynas Kalensinskas, Evan Cudone, Yuriy Fofanov, Catherine Putonti

Bioinformatics Faculty Publications

With the daily release of data from whole genome sequencing projects, tools to facilitate comparative studies are hard-pressed to keep pace. Graphical software solutions can readily recognize synteny by measuring similarities between sequences. Nevertheless, regions of dissimilarity can prove to be equally informative; these regions may harbor genes acquired via lateral gene transfer (LGT), signify gene loss or gain, or include coding regions under strong selection. Previously, we developed the software S-plot. This tool employed an alignment-free approach for comparing bacterial genomes and generated a heatmap representing the genomes’ similarities and dissimilarities in nucleotide usage. In prior studies, this tool …

Bionic Wings, Jacob Bruggeman

Compass: An Undergraduate Journal of American Political Ideas

In an infinite expanse such as the one we inhabit, we are mere mites in the soil, “creatures weak and fragile, small and helpless, finite and mortal” (Tucker, First Things, online). Our eyes always fixed upon the future, blooming ad infinitum, we will “run faster,” “stretch” ourselves farther, yet never fail to fall back to the ground. Our hands in the dirt, our fingers moving upon blades of grass, we still hunger for a future of our own design. We are born without wings and bogged down by both our human history and our only true human birthright: to fail, …

Dethroning State Security: Introducing A Human Security Perspective To Absorb The Dangers Of Climate Change To The Self-Determination Of Island State Inhabitants, Anemoone Soete

Buffalo Environmental Law Journal

One unmistakable and indisputable consequence of Climate Change is found in the realm of oceans. Sea-levels are currently rising at a pace unknown to mankind and as a consequence island states are destined to lose habitable land territory. Whereas some may lose parts, others will lose all of it in the current business as usual scenario. This reality first begs the question as to whether an island state will continue to be a state once bereft of a territorial basis. Secondly, it must be considered how islanders might retain legal personality should this is no longer be possible through the …

To Kill A Migratory Bird: How Incidental Takes By Commercial Industry Activity Should Be Regulated By A New Civil Penalty Regime, Not The Current Mbta, Brittany E. Barbee

Buffalo Environmental Law Journal

Migratory birds are at odds with commercial industries in the United States. Industries are occasionally and accidentally killing migratory birds through their legal activity. Such actions against migratory birds are known as incidental takes. While the century-old Migratory Bird Treaty Act (MBTA) prohibits the taking of migratory birds, it is unclear as to whether it prohibits these modern-day incidental takes. The MBTA imposes criminal strict liability on those who violate its prohibitions, regardless of one's mental state at the time of the incident. Should the federal government hold commercial industries criminally liable for incidentally taking migratory birds through otherwise legal …

A Targeted Genetic Screen To Identify Meiotic Cohesin Regulators, Urja Patel, Emilia Kalutskaya, Alexis Brown, Ali Ahsan

Undergraduate Research Posters 2018

During oogenesis in animals deficient for REC-8, a cohesin subunit required for sister chromatids cohesin (SCC), Co recombination fails and sister chromatids segregate away from one another prematurely in meiosis I. Consequently, zygotes inherit two copies of each chromosome. Chromosome segregation in meiosis II fails and the progeny of rec-8 mutant mothers usually survive as viable polyploids. In contrast, homologs segregate randomly during meiosis I in oocytes produced by spo-11 mutants, which lack the transesterase required for crossover recombination. This results in aneuploidy, and nearly all the embryos die. We have shown that mutations disrupting SCC mediated by REC-8 cohesion, …

Methodology Development For The Implementation Ofmicrofluidic Mixers, Tahir Butt, Gautam Mahajan

Undergraduate Research Posters 2018

Microfluidic platforms have been widely regarded as defining technologies for the development of chemical and biological synthesis and analysis systems, due to benefits associated with reduced reactant consumption, increases by orders of magnitude of the surface-to-volume ratios, and greatly enhanced control over reactions variables such as temperature and pressure. However, one of the bottlenecks for their wide application is the difficulty in achieving mixing, given the typical laminar flows in these systems. In this work we implement experimentally, various strategies using geometrical features to control the fluid motion and induce stirring flows. The mixers are fabricated using soft-lithography in PDMS …

Surface Functionalization Of Pure-Chirality Carbon Nanotubes By Covalent And Noncovalent Chemistry, Fjorela Xhyliu, Niyousha Mohammad Shafie

Undergraduate Research Posters 2018

Single-wall carbon nanotubes (SWCNTs) are one-dimensional cylindrical nanostructures with distinct electronic and optical properties. With all its atoms on the surface, SWCNTs have been widely explored for chemical modification through noncovalent and covalent chemistry, which can provide promising applications in bioimaging and sensing. Here we investigated surface functionalization of purechirality SWCNTs with various glycopolymers, surfactants, and RPMI cell culture media with and without fetal bovine serum (FBS). Raman, vis-NIR absorption, and vis-NIR fluorescence spectra of SWCNTs in various solvent environments were monitored over time. While nanotube aggregation was not observed for incubation in FBS containing RPMI for 8 hours, interactions …

Evaluating Intellectual Disability: Clinical Assessments In Atkins Cases, James W. Ellis, Caroline Everington, Ann M. Delpha

Faculty Scholarship

The intersection of intellectual disability and the death penalty is now clearly established. Both under the U.S. Supreme Court’s constitutional decisions and under the terms of many state statutes, individual defendants who have that disability cannot be sentenced to death or executed. It now falls to trial, appellate, and post-conviction courts to determine which individual criminal defendants are entitled to the law’s protection. This Article attempts to assist judges in performing that task. After a brief discussion of the Supreme Court’s decisions in Atkins v. Virginia, Hall v. Florida, and Moore v. Texas, it analyzes the component parts and terminology …

Growth Rate And Hatch Date Of Age-0 Fishes On Leech Lake, Minnesota Before Zebra Mussel Establishment, Kayla Morey, Emily Larson

Journal of Earth and Life Science

The introduction of an invasive species to an ecosystem is considered a very severe environmental problem. Zebra Mussel veligers Dreissena polymorpha have recently been found in Leech Lake, Minnesota, and are likely going to have a large influence on this ecosystem. Zebra Mussels are filter-feeders that rely on phytoplankton and zooplankton as their main source of energy. A shift in populations of plankton due to Zebra Mussels may affect the growth rates of larval fish. Median hatch dates and growth rates were estimated from four age-0 fish species (Yellow Perch Perca flavescens, Walleye Sander vitreus, Smallmouth Bass Micropterus …
