Quantitating Active Photosystem Ii Reaction Center Content From Fluorescence Induction Transients, Cole D. Murphy, Guangyan Ni, Gang Li, Audrey Barnett, Kui Xu, Jessica Grant-Burt, Justin D. Liefer, David J. Suggett, Douglas A. Campbell

Michigan Tech Publications, Part 1

Photosystem II (PSII) is a pigment-protein complex that photochemically extracts electrons from water, generating the reductant that supports biological productivity in all biomes. Estimating the content of active PSII reaction centers in a liquid sample is a key input for estimating aquatic photosynthesis rates, as well as for analyzing phytoplankton stress responses. Established procedures for PSII content quantification based on oxygen evolution are slow, imprecise and require dense cell suspensions, and are thus inapplicable to many laboratory or field studies. A new approach uses baseline chlorophyll fluorescence emission divided by the effective absorbance cross section for PSII photochemistry, with both …

Statistical Shape Modeling To Quantify Variation In The Proximal Humeral Anatomy, Paul B. Sade Sr.

Electronic Theses and Dissertations

The fit of the humeral prosthesis to the intramedullary canal and the replication of the anatomic humeral head center are important factors in Total Shoulder Arthroplasty (TSA). The objective of this thesis was to develop a Statistical Shape Model (SSM) of the cortical and cancellous bone regions of the proximal humerus, and to assess potential shape differences with gender and ethnicity, with a goal of informing implant design. An SSM was used and Principal Component Analysis (PCA) was applied to data that represented both the cancellous and cortical humeral bone of 63 healthy subjects and cadavers. Anatomical measurements and PC …

Ior Methods In Unconventional Reservoirs Of North America: Comprehensive Review, Dheiaa Alfarge, Mingzhen Wei, Baojun Bai

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Unconventional resources have played a significant role in changing oil industry plans recently. Shale formations in North America have huge oil in place, 900 billion barrels of recoverable oil in Bakken only. However, the predicted primary recovery is still low as less than 10%. Therefore, seeking for improved oil techniques to increase oil recovery in these complex plays is inevitable. In this paper, three stages of review have been combined to find out the applicability of the most feasible IOR methods in these unconventional reservoirs. Firstly, the most common fluid and rock properties of these reservoirs have been investigated and …

Selection Criteria For Miscible-Gases To Enhance Oil Recovery In Unconventional Reservoirs Of North America, Dheiaa Alfarge, Mingzhen Wei, Baojun Bai, Mortadha Alsaba

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Unconventional resources have played a significant role in changing oil industry plans recently. Shale formations in North America such as Bakken, Niobrara, and Eagle Ford have huge oil in place, 100-900 billion barrels of oil in Bakken only. However, the predicted primary recovery is still low as 5-10%. Therefore, seeking for techniques to enhance oil recovery in these complex plays is inevitable. In this paper, two different approaches have been integrated to investigate the feasibility of three different miscible gases which are CO₂, lean gases, and rich gases. Firstly, numerical simulation methods of compositional models have been incorporated …

Wellbore Stability Evaluation For Mishrif Formation, Ethar H.K. Alkamil, Husam R. Abbood, Ralph E. Flori, Andreas Eckert

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

During drilling operations for the E oilfield in the Mishrif formation in southern Iraq, stuck pipe has been identified as a significant geomechanical problem for several wells. In this study, a 1-D mechanical earth model (MEM) of the Mishrif formation is compiled based on its state of stress and rock strength parameters and is utilized to assess the contribution of borehole collapse leading to the stuck pipe problems. The MEM model is based on the principal in situ stresses and their orientation obtained from wireline logs measurements, measuring while drilling (MWD), and leak off test (LOT). Rock strength properties are …

Effect Of Molecular-Diffusion Mechanisim On Co2 Huff-N-Puff Process In Shale-Oil Reservoirs, Dheiaa Alfarge, Mingzhen Wei, Baojun Bai, Abdullah Almansour

Unconventional resources have played a significant role in changing oil industry plans recently. Shale formations in North America such as Bakken, Niobrara, and Eagle Ford have huge oil in place, 100-900 billion barrels of recoverable oil in Bakken only. However, the predicted primary recovery is still low as less than 10%. Therefore, seeking for techniques to increase oil recovery in these complex plays is inevitable. In this paper, three different approaches have been combined to investigate the effect of molecular-diffusion mechanism on CO₂ huff-n-puff process in Bakken formation. Firstly, comprehensive review has been conducted on the reported experimental studies …

Optimizing Injector-Producer Spacing For Co2 Injection In Unconventional Reservoirs Of North America, Dheiaa Alfarge, Mingzhen Wei, Baojun Bai, Abdullah Almansour

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Shale oil reservoirs such as Bakken, Niobrara, and Eagle Ford have become the main target for oil and gas investors as conventional formations started to deplete and diminish in number. These reservoirs have a huge oil potential; however, the predicted primary oil recovery is still low as average of 7.5 %. Carbon dioxide (CO₂) flooding has been a controversial approach to increase oil recovery in these poor-quality formations. This study investigated the effect of injector-producer spacing, in range of 925-1664 ft, on CO₂ performance in these plays by using numerical simulation methods. CO₂ utilization value under …

Novel Environmentally Benign Hydrogel: Nano-Silica Hybrid Hydrolyzed Polyacrylamide/ Polyethyleneimine Gel System For Conformance Improvement In High Temperature High Salinity Reservoir, Liping Ma, Shitou Wang, Yifu Long, Changqian Zhu, Hongbin Yang, Tangying Yang, Xiaochun Liu, Xiaorong Li, Baojun Bai, Wanli Kang

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

In order to address the conformance problem in high temperature and high salinity/hardness reservoir, an environmentally benign in-situ gel was developed based on hydrolyzed polyacrylamide (HPAM) and polyethyleneimine (PEI). Moreover, silica nanoparticle (SNP) was embedded to improve the performance of HPAM/PEI gel. To achieve the optimum formulation of HPAM/PEI-SNP gel, a comprehensive investigation was first conducted with the respect of gelation time, gel strength, and thermal stability. In addition, the particle size of SNP was determined by Dynamic Light Scatter (DLS) and the microstructure of HPAM/ PEI-SNP gel was characterized via Scanning Electron Microscopy (SEM). The optimum formulation, containing the …

Linking A Dermal Permeation And An Inhalation Model To A Simple Pharmacokinetic Model To Study Airborne Exposure To Di(N-Butyl) Phthalate, Matthew Lorber, Charles J. Weschler, Glenn Morrison, Gabriel Bekö, Mengyan Gong, Holger M. Koch, Tunga Salthammer, Tobias Schripp, Jørn Toftum, Geo Clausen

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Six males clad only in shorts were exposed to high levels of airborne di(n-butyl) phthalate (DnBP) and diethyl phthalate (DEP) in chamber experiments conducted in 2014. In two 6 h sessions, the subjects were exposed only dermally while breathing clean air from a hood, and both dermally and via inhalation when exposed without a hood. Full urine samples were taken before, during, and for 48 h after leaving the chamber and measured for key DnBP and DEP metabolites. The data clearly demonstrated high levels of DnBP and DEP metabolite excretions while in the chamber and during the first 24 h …

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

We present probabilistic and deterministic seismic and liquefaction hazard maps for the densely populated St. Louis metropolitan area that account for the expected effects of surficial geology on earthquake ground shaking. Hazard calculations were based on a map grid of 0.005°, or about every 500 m, and are thus higher in resolution than any earlier studies. To estimate ground motions at the surface of the model (e.g., site amplification), we used a new detailed near-surface shear-wave velocity model in a 1D equivalent- linear response analysis. When compared with the 2014 U.S. Geological Survey (USGS) National Seismic Hazard Model, which uses …

A Study Of Scattering From Snow Embedded With Non-Spherical Shapes Of Scatterers With Relaxed Hierarchical Equivalent Source Algorithm (Rhesa), Chan Fai Lum, Fu Xin, Hong Tat Ewe, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Remote sensing has been used widely in studying the earth terrain such as snow or sea ice due to its fast, convenient and long-term monitoring capabilities. SAR images acquired could be used to analyze the condition of snow, snow water equivalent (SWE), surface roughness and others. Theoretical models have also been developed to understand how microwave interacts with the snow medium and the scatterers embedded inside the medium. Conventionally, spherical shape of scatterers is commonly used to represent the ice particles embedded inside snow where the actual shape of scatterers can vary. This paper is to present a theoretical model …

Masculinity On Women In Japan: Gender Fluidity Explored Through Literature And Performance, Jessica M. Perreira

Scripps Senior Theses

The first half of my thesis are my translations from Yumi Hirosawa’s Onna O Aisuru Onnatachi. The first translation is excerpts from a high school girls journal documenting her realization and acceptance of being lesbian, and her time with her first girlfriend. The second translation is a report by a freelance writer on three different lesbian bars in Shinjuku Ni-Chome. The most notable bar is an onabe bar called Little Prince. Onabe in the simplest terms are women who dress and act like men. Onabe are important to the research portion of my thesis because they allowed me to research …

The Rise Of The Far Right: Explaining Popularity And Potential Influence, Vanessa Rosato

Scripps Senior Theses

The 2016 election cycle has shown a dramatic radicalization of the right, featuring elements such as out-group demonization, law and order rhetoric, and populist strategies that have not been so prevalent in the US since the rise of Nixon’s Silent Majority in the 1970s. The UK has experienced a similar ideological shift, though its emergence has perhaps not been so notoriously outspoken. All the same, the fervent anti-statist and anti-elitist narrative employed by the Leave Campaign is starkly similar to language historically associated with the populist rhetoric of the Far Right. Drawing on analyses of economic, socio-cultural, and geopolitical trends …

Isolation And Spectroscopic Characterization Of Zn(Ii), Cu(Ii), And Pd(Ii) Complexes Of 1,3,4-Thiadiazole-Derived Ligand, Dariusz Karcz, Arkadiusz Matwijczuk, Bozena Boron, Bernadette Creaven, Leszek Fiedor, Andrzej Niewiadomy, Mariusz Gagos

Articles

A series of complexes incorporating Zn(II), Cu(II), and Pd(II) ions, and 4-(5-heptyl-1,3,4-thiadiazol-2-yl)benzene-1,3-diol (L1) as model ligand, was synthesized in order to examine the nature of potential interactions between biologically active ligands, 1,3,4-thiadiazoles and metal ions with proven biological relevance. The structures of the compounds isolated were characterized using a number of spectroscopic methods including IR, Uv–vis, AAS, steady state and time-resolved fluorescence (TRF). The results obtained suggest that the L1-Zn(II) and L1-Pd(II) complexes consist of one molecule of L1 and one acetate ion acting as ligands, while the L1-Cu(II) complex adapts a 2:1 (L1: metal) stoichiometry. The coordination of L1 …

Informal, Inquisitorial, And Accurate: An Empirical Look At A Problem-Solving Housing Court, Jessica K. Steinberg

GW Law Faculty Publications & Other Works

Substantive justice is often seen as elusive in courts dominated by low-income individuals. Complex court rules, coupled with pervasive lack of counsel, can make it difficult for the traditional adversary process to identify and redress legitimate grievances. This Article takes on the social problem of substandard housing and examines whether inquisitorial procedure has the potential to produce accurate outcomes in a tribunal dominated by the unrepresented.

Relying on in-court observations of nearly 300 hearings, and a longitudinal review of nearly 75 cases, this Article surfaces the regularized procedures utilized by a purported “problem-solving” housing court, and theorizes that the inquisitorial …

The Mystery Of Unanimity In Hosanna-Tabor Evangelical Lutheran Church & School V. Eeoc, Ira C. Lupu, Robert W. Tuttle

GW Law Faculty Publications & Other Works

In Hosanna-Tabor Evangelical Lutheran Church & School v. EEOC (2012), the Supreme Court held that the First Amendment supports a “ministerial exception” defense in anti-discrimination suits by clergy against their institutional religious employers. In advance of the decision, the outcome seemed unpredictable, and the Court’s unanimity arrived as a shock.

This paper illuminates the result, reasoning, and unanimity in Hosanna-Tabor. We explain how Hosanna-Tabor stands in a long line of decisions, grounded in both the Establishment Clause and the Free Exercise Clause, that prohibit state adjudication of “strictly and purely ecclesiastical" questions.

Part I examines why unanimity on the Supreme …

The Holding-Dicta Spectrum, Andrew Michaels

GW Law Faculty Publications & Other Works

The distinction between holding and dictum is often treated under a binary paradigm; either a proposition is binding holding, or unconstraining dictum. But the binary paradigm is too simplistic to adequately model our complex system of precedent. This article suggests an alternative spectrum paradigm where the constraining force of a precedent proposition is inversely correlated with its breadth. This article explains the spectrum approach, compares it with prevailing approaches, and evaluates some cases in light of the spectrum model. The spectrum framework has the potential to facilitate judicial candor and make the concepts of holding and dicta more consistently meaningful.

Agency Behavior And Discretion On Remand, Robert L. Glicksman, Emily Hammond

GW Law Faculty Publications & Other Works

Despite the prevailing focus of administrative law on judicial review of agency discretion, scholars are increasingly asking what we can learn about agency discretion in the absence of judicial review. Indeed, such work prompts a reexamination of administrative law and our assumptions about agencies’ legitimacy. When a court invalidates an agency action, the agency’s response on remand is often left open to the agency’s discretion. Agencies frequently have significant latitude in whether, how, and when (if ever) to remedy the initial flaw.

What is the extent of agency discretion following a remand, and how do agencies use that discretion? In …

Identifying Anticompetitive Agreements In The United States And The European Union: Developing A Coherent Antitrust Analytical Framework, William E. Kovacic

GW Law Faculty Publications & Other Works

Commentary in both the US and the EU has repeatedly debated whether, and when, it is more efficient to use “rules” or “standards” to determine the legality of conduct subject to the antitrust laws and how such rules or standards should be formulated. This paper concentrates principally on the question of how this debate impacts on the analyticalframework for identifying infringing agreements in the US and EU. It sets out the view that the question of how agreements are to be analysed under both the US and the EU jurisprudence is unduly opaque. Confusion as to, in particular, the role …

Civil Procedure And The Ministerial Exception, Peter J. Smith, Robert W. Tuttle

GW Law Faculty Publications & Other Works

In Hosanna-Tabor Evangelical Lutheran Church and School v. Equal Employment Opportunity Commission, the Court recognized a ministerial exception to the ordinary rules of employer liability. The Court also concluded that the exception operates as an affirmative defense rather than a jurisdictional bar. This conclusion raises quite significant questions about how courts should address the exception in the course of litigation.

We argue that courts should approach these procedural questions in light of the underlying justification for the ministerial exception. The exception reflects a longstanding constitutional limitation on the competence of courts to resolve “strictly and purely ecclesiastical” questions. To conclude …

Comparing The Competition Law Regimes Of The United States And India, Richard J. Pierce Jr

GW Law Faculty Publications & Other Works

In this article, Professor Pierce compares the oldest system of competition law—the U.S. system—with one of the youngest systems of competition law—the Indian system. He identifies several strengths and weaknesses of the U.S. system. He then gives the Indian Parliament high marks for creating an institutional environment that has the potential to produce an excellent body of law.

Heteronormativity In Employment Discrimination Law, Naomi Schoenbaum

GW Law Faculty Publications & Other Works

This symposium Essay responds to the EEOC’s new decision to interpret federal employment discrimination law’s ban on discrimination on the basis of sex to include a ban on discrimination on the basis of sexual orientation. It argues that although the EEOC’s decision does provide cause to celebrate, ongoing heteronormativity in federal employment discrimination law will continue to stand as a barrier to equal employment opportunity for gay workers. First, Title VII provides an exception to the sex discrimination ban in the context of intimate spaces, allowing, for example, only women to be hired to serve as labor and delivery nurses. …

Risky Business: Should The Fda Pay Attention To Pharmaceutical Prices?, David A. Hyman, William E. Kovacic

GW Law Faculty Publications & Other Works

People are angry about drug prices. What role, if any, should the FDA play in addressing this issue? Historically, the FDA’s answer has been “not our problem.” As the quality and safety agency, the FDA has repeatedly refused to get involved in drug pricing matters, even when its actions (and inactions) have contributed to the problem. We examine the circumstances under which the FDA should pay attention to pharmaceutical prices, and discuss the implications of it doing so.

Awareness As A First Step Toward Overcoming Implicit Bias, Cynthia Lee

GW Law Faculty Publications & Other Works

In this book chapter, Cynthia Lee explains that raising awareness of implicit bias is a necessary first step toward eliminating such bias. Lee discusses various ways legal actors can raise awareness about implicit bias, including implicit bias trainings and jury instructions attempting to educate jurors about implicit bias. She concludes that making racial bias (or other types of bias) salient is probably the most effective way to raise awareness of implicit bias in the courtroom setting and discusses the social science literature that supports this conclusion. In light of some studies suggesting that making bias salient may backfire, she suggests …

Properly Funding The Copyright Office: The Case For Significantly Differentiated Fees, Robert Brauneis

GW Law Faculty Publications & Other Works

The United States Copyright Office performs a variety of functions crucial to the copyright system. Through its core registration and recordation functions, it provides critical information about the authorship, ownership, and copyright status of millions of works of authorship created over the last century; it also advises Congress, other federal agencies, and the courts on copyright law; conducts studies on various aspects of copyright law; participates in international meetings; produces educational programs and publications; and engages in many other activities relating to the administration of copyright law. However, the Copyright Office is seriously underfunded, compromising all of its functions. The …
