Neuromodulation With Electromagnetic Stimulation For Seizure Suppression: From Electrode To Magnetic Coil, Hui Ye, Stephanie Kaszuba

Biology: Faculty Publications and Other Works

Non-invasive brain tissue stimulation with a magnetic coil provides several irreplaceable advantages over that with an implanted electrode, in altering neural activities under pathological situations. We reviewed clinical cases that utilized time-varying magnetic fields for the treatment of epilepsy, and the safety issues related to this practice. Animal models have been developed to foster understanding of the cellular/molecular mechanisms underlying magnetic control of epileptic activity. These mechanisms include (but are not limited to) (1) direct membrane polarization by the magnetic field, (2) depolarization blockade by the deactivation of ion channels, (3) alteration in synaptic transmission, and (4) interruption of ephaptic …

Biology Faculty Publications

We analyse the impact of ship traffic in the vicinity of navigation channels in a wide shallow waterbody. The crucial hydrodynamic driver in this situation is the depression (Bernoulli) wake that may be transferred into a long-living solitary wave of depression over the shoals. The analysis considers navigation channels in the Venice Lagoon using a new large dataset of approximately 600 measured wake events associated to specific ships whose data are provided by the AIS system. Since the development of the modern industrial port and the opening of the Malamocco–Marghera channel in the late 1960s, growing pressure on the lagoon …

Feasibility Analysis Of Adipic Acid Production, Serpil Unlu

Department of Chemical and Biomolecular Engineering: Dissertations, Theses, and Student Research

Adipic acid is an essential intermediate chemical feedstock for the production of nylon-6,6; hence it is valuable from an industrial perspective. Currently, commercial adipic acid production includes a combination of two stages. The first stage produces a mixture of cyclohexanone and cyclohexanol called ‘’KA oil” derived from cyclohexane. In the second stage, KA oil is reacted with nitric acid to produce adipic acid. The second stage generates excess N₂O emission, which is considered as 310 times more potent than CO₂. Renewable feedstocks that can be converted to value-added chemicals offer significant potential for the necessary transition …

Policing The Painted And Powdered, Anthony Michael Kreis

Cardozo Law Review

Is homophobia also sexism?

This question was the focus ofpioneering scholarship nearly three decades ago and has been the subject ofreignited controversy because of litigation over marriage rights, employment discrimination, educational opportunities, fair housing, religious exemptions, and military service. Even though some courts, federal agencies, and state employment commissions have recognized that sexual orientation and gender identity discrimination are subsets ofsex discrimination, including the landmark Title VII decisions Hively v. Ivy Tech Community College and Zarda v. Altitude Express, academics, judges, andpublic administrators have been unable to articulate a plain theory ofsexual orientation discrimination as sexism. Without a straightforward theory …

The Role Of A Peer-Led Academic Intervention In College Students' Development Of Self-Regulated Learning: A Person-Centered Approach, Soojeong Jeong

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to its unsupervised nature, undergraduate education requires students to manage their own learning. They need to use self-regulated learning (SRL) strategies in order to achieve academic success. However, college students often have insufficient regulatory skills and strategies, suggesting the need for substantive and practical support. Supplemental Instruction (SI) is a well-recognized academic intervention that utilizes peer-led study groups for difficult college courses, through which students can develop their SRL abilities.

This study focuses on the role of the SI program in college students’ development of SRL from a person-centered perspective. First, this study examines the heterogeneous effects of the …

A Model Explaining Medusahead Invasion And Novel Targeted Grazing Approaches Of Control, Casey N. Spackman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Medusahead (Taeniatherum caput-medusae (L.) Nevski) is currently one of the biggest threats to rangelands and livestock operations in the Western US. High silica concentrations in medusahead contribute to its invasiveness. I developed a model to explain how silica is involved in the invasion process, and attempted to manipulate silica to increase use of the grass by livestock. Experiments were conducted to determine: 1) whether rotational grazing on established forages of improved nutritional quality would provide supplemental nutrients to increase cattle use of medusahead; 2) evaluate intake of and preference for medusahead treated with a glyphosate herbicide at different rates …

Abc Transporter Genes Abc-C6 And Abc-G33 Alter Plant-Microbe-Parasite Interactions In The Rhizosphere, Deborah Elizabeth Cox, Steven Dyer, Ryan Weir, Xavier Cheseto, Matthew Sturrock, Danny Coyne, Baldwyn Torto, Aaron G. Maule, Johnathan J. Dalzell

All Peer-Reviewed Publications

Plants are master regulators of rhizosphere ecology, secreting a complex mixture of compounds into the soil, collectively termed plant root exudate. Root exudate composition is highly dynamic and functional, mediating economically important interactions between plants and a wide range of soil organisms. Currently we know very little about the molecular basis of root exudate composition, which is a key hurdle to functional exploitation of root exudates for crop improvement. Root expressed transporters modulate exudate composition and could be manipulated to develop beneficial plant root exudate traits. Using Virus Induced Gene silencing (VIGS), we demonstrate that knockdown of two root-expressed ABC …

Thermococcus Thioreducens' Inorganic Pyrophosphatase Purification, Christopher Nozum, Zeina Sleiman

Perpetua: The Journal of Undergraduate Research at UAH

Protein purification requires an intensive multi-step process that is customized to every protein’s characteristic for optimal results. In this study, we looked at the purification process of Inorganic Pyrophosphatase (IPPase), an essential protein found in all living organisms. The commonality of the protein does not veil the fact that the mechanism by which IPPase is hydrolyzed into two orthophosphates is not fully understood. To comprehend the mechanism, recombinant mutants of the conservative region in IPPase were expressed. However, to observe a possible change in structure of the recombinant mutants with crystallization, pure concentrated protein is needed. Therefore, protein purification is …
