Effect Of Additives On Mineral Trioxide Aggregate Setting Reaction Product Formation, Angela M. Zapf, Sharath C.V. Chedella, David W. Berzins

School of Dentistry Faculty Research and Publications

Introduction

Mineral trioxide aggregate (MTA) sets via hydration of calcium silicates to yield calcium silicate hydrates and calcium hydroxide (Ca[OH]₂). However, a drawback of MTA is its long setting time. Therefore, many additives have been suggested to reduce the setting time. The effect those additives have on setting reaction product formation has been ignored. The objective was to examine the effect additives have on MTA's setting time and setting reaction using differential scanning calorimetry (DSC).

Methods

MTA powder was prepared with distilled water (control), phosphate buffered saline, 5% calcium chloride (CaCl₂), 3% sodium hypochlorite (NaOCl), or …

Through The Looking Glass To A Shared Reflection: The Evolving Relationship Between Administrative Law And Financial Regulation, Gillian E. Metzger

Faculty Scholarship

Administrative law and financial regulation have an uneasy relationship today. It was not always so. Indeed, the two were closely intertwined at the nation's birth. The Treasury Department was a major hub of early federal administration, with Alexander Hamilton crafting the first iterations of federal administrative law in his oversight of revenue generation and customs collection. One hundred and fifty years later, administrative law and financial regulation were conjoined in the New Deal's creation of the modern administrative state. This time it was James Landis, Chair of the newly formed Securities and Exchange Commission (SEC) and author of the leading …

Appointments, Innovation, And The Judicial-Political Divide, Gillian E. Metzger

Faculty Scholarship

The federal appointments process is having its proverbial day in the sun. The appointment and removal of federal officers figured centrally in the Supreme Court's two major recent separation-of-powers decisions, Free Enterprise Fund v. Public Company Accounting Oversight Board and National Labor Relations Board v. Noel Canning. The appointments process has featured even more prominently in the political sphere, figuring in a number of congressional-presidential confrontations. Such simultaneous top billing in the judicial and political spheres is hardly coincidental. After all, it was President Obama's use of the Recess Appointments Clause in response to pro forma sessions that triggered …

Monroe Freedman: Servant Leader, Bridge Builder, Susan Saab Fortney

Faculty Scholarship

Without question, Monroe was dedicated to serving others, wholeheartedly committed to helping clients and community members achieve their potential. As many have attested, Monroe epitomized the servant leader who freely gives time and support to others. I hope that the many people whom Monroe touched will continue to be sustained by Monroe’s ethic of service.

Intellectual Property Infringement As Vandalism, Irina D. Manta, Robert E. Wagner

Hofstra Law Faculty Scholarship

Defenders of strong intellectual property rights often maintain that intellectual property infringement is theft and that the sanctions associated with it ought to be high. Others are skeptical of the property comparison and think that much lower sanctions are appropriate.

In this Article, we argue that a careful analysis demonstrates: 1) that intellectual property infringement can be analogized to a property crime, but 2) that the more analogous crime is vandalism or trespass rather than theft. This categorization takes the rhetorical punch out of the property comparison. In addition to analyzing the natures of the various offenses, this Article investigates …

Attending To Reality: Iris Murdoch On The Moral Good, Ante Jeroncic

Faculty Publications

Even a scant acquaintance with current cultural and philosophical trends will readily point to a widespread predilection for subjectivist forms of moral reasoning. By “subjectivist” I refer to various non-cognitivist and constructionist paradigms in moral philosophy and popular parlance that reduce ethical statements to expressions of individual or collective preferences, feelings, or prejudices stripped of any object-given normativity. Th e following are but some of the factors that fuel such perspectives: the proverbial fact/value dichotomy and anti-realist sentiments pervading large swaths of analytic philosophy; poststructuralist and postcolonial “genealogies” that tie the language of universal morality to discourses of power, patriarchy, …

No Execution If Four Justices Object, Eric M. Freedman

Hofstra Law Faculty Scholarship

I. DRIVING A NAIL WITH A SCREWDRIVER IN CAPITAL CASES

Today’s Supreme Court defines its role as choosing from the thousands of cases pressed upon it annually those very few that will best serve as vehicles for the resolution of legal issues of general importance.

1. A. Ordinary Cases

(1) The necessary consequence is that some litigants will seek review and fail to attain it for reasons having nothing to do with the merits of their claims (e.g., the Court desires to have the issue percolate for a while in the lower courts or in the public arena), and will find …

Trotting Out The White Horse: How The S.E.C. Can Handle Bitcoin’S Threat To American Investors, J. Scott Colesanti

Hofstra Law Faculty Scholarship

Bitcoin has entered the kingdom to stay, yet few are willing to shield its most likely victims.

The cryptocurrency is a mysterious amalgam of technology, transparency, and secrecy. Despite its initial mission of bypassing commercial fees, the currency alternative, presently valued at over $400 a coin, is a more likely candidate for hoarding and speculation. Surprisingly, while its brazen use to facilitate money laundering and drug purchases have been met with prosecution and headlines, Bitcoin’s everyday rapidly growing appeal to investors has been left largely unaddressed.

As an investment, Bitcoin’s chief marketing tool appears to be conversion mechanisms declaring themselves …

Lgbtq Relationships, Barbara J. Stark

Hofstra Law Faculty Scholarship

Perhaps nowhere in family law is this evolution more dramatic than in the burgeoning recognition of rights of lesbian, gay, bisexual, transgendered, and questioning (LGBTQ) couples. Within the past twenty- five years courts, legislatures, and international bodies have addressed the extent to which rights and obligations formerly reserved to heterosexual married spouses should be conferred on other partners.

Most western democracies now recognize same- sex unions, assuring the partners in such unions a range of rights and benefits, similar to but distinct from the rights and benefits enjoyed by married couples. Part A of this Chapter describes the legal mechanisms …

On Bargaining For Development, Timothy M. Mulvaney

Faculty Scholarship

In his recent article, Bargaining for Development Post-Koontz, Professor Sean Nolon concludes that the Supreme Court’s recent ill-defined expansion of the circumstances in which land use permit conditions might give rise to takings liability in Koontz v. St. John’s River Water Management District will chill the state’s willingness to communicate with permit applicants about mitigation measures. He sets out five courses that government entities might take in this confusing and chilling post-Koontz world, each of which leaves something to be desired from the perspective of both developers and the public more generally.

This responsive essay proceeds in two parts. First, …

De Novo Protein Structure Modeling And Energy Function Design, Lin Chen

Computer Science Theses & Dissertations

The two major challenges in protein structure prediction problems are (1) the lack of an accurate energy function and (2) the lack of an efficient search algorithm. A protein energy function accurately describing the interaction between residues is able to supervise the optimization of a protein conformation, as well as select native or native-like structures from numerous possible conformations. An efficient search algorithm must be able to reduce a conformational space to a reasonable size without missing the native conformation. My PhD research studies focused on these two directions.

A protein energy function—the distance and orientation dependent energy function of …

Modeling And Simulation Of Molecular Couette Flows And Related Flows, Wei Li

Mathematics & Statistics Theses & Dissertations

In this thesis, molecular Couette flow is clearly defined and the modeling and simulation of this kind of flow is systematically investigated. First, the integral equations for the velocity of gaseous Couette flow and related flows are derived from linearized Boltzmann BGK equation with Maxwell boundary condition and solved with high precision by using Chebyshev collocation and chunk-based collocation methods. The velocity profiles of gaseous Couette flows and related flows with a wide range of Knudsen number and the Maxwell boundary condition of various accommodation ratios are obtained. Moreover, the order of convergence of the numerical methods is also discussed …

Correcting The Record Regarding Therestatement Of Property’S Slayer Rulein The Brooklyn Law Review’Ssymposium Issue On Restatements, Lawrence W. Waggoner, John H. Langbein

Articles

In 2014, the Brooklyn Law Review published a symposium issue on Restatements of the Law. The organizer of the symposium, Professor Anita Bernstein, did not afford an opportunity for Restatement reporters to comment on the articles. The organizer did invite the Director of the American Law Institute, Lance Liebman, to contribute an essay commenting on the symposium as a whole. Liebman’s essay—unintentionally no doubt—misstated the position that we took in formulating the slayer rule for the Restatement (Third) of Property: Wills and Other Donative Transfers. Liebman’s misstatement—that we recommended that the Institute adopt a rule allowing a murderer to inherit …

Abdominal Lymphonodular Cryptococcosis In An Immunocompetent Child, Mehjabeen Zaidi, Sonia Qureshi, Sadia Shakoor, Saira Fatima, Fatima Mir

Department of Paediatrics and Child Health

We describe our experience with an apparently immunocompetent child presenting with pyrexia of unknown origin without focal signs. Investigations revealed lymphadenopathy at lung hila, mesentery, and porta hepatis. The child had received at least two months of empiric antituberculous therapy (ATT) before she came to us. A CT-guided biopsy revealed granulomatous inflammation. PAS stain showed yeasts which stained blue with Alcian blue, suggesting C. neoformans.

Can Routine Screening And Iron Supplementation For Iron Deficiency Anemia In Nonsymptomatic Pregnant Women Improve Maternal And Infant Health Outcomes?, Anoosh Moin, Zohra S. Lassi

Department of Paediatrics and Child Health

Pregnant women have an increased need for iron that might not be met with diet alone. Due to physiologic anemia and population differences, no set criteria for defining iron deficiency anemia (IDA) are available globally. Serum ferritin and transferrin levels are often used to guide therapy by clinicians. Studies have reported an association between poor iron status and negative health outcomes such as low birth weight, premature birth, and perinatal death for women and their infants, although the evidence is weak.

Department of Paediatrics and Child Health

Background: Breast milk contains anti-rotavirus IgA antibodies and other innate immune factors that inhibit rotavirus replication in vitro. These factors could diminish the immunogenicity of oral rotavirus vaccines, particularly if breastfeeding occurs close to the time of vaccine administration.
Methods: Between April 2011 and November 2012, we conducted an open label, randomized trial to compare the immunogenicity of Rotarix (RV1) in infants whose breastfeeding was withheld one hour before through one hour after vaccination with that in infants breastfed at the time of vaccination. The trial was conducted in the peri-urban area of Ibrahim Hyderi in Karachi, Pakistan. Both groups …

Revisiting The Revolution: Reintegrating The Wealth Transmission System, Melanie B. Leslie, Stewart E. Sterk

Articles

Thirty years ago, John Langbein published "The Nonprobate Revolution and the Future of Succession." The article celebrated testators' newfound ability to avoid the expense and delay of the probate court system by holding assets in a variety of non-probate devices, such as retirement and bank accounts with beneficiary designations and revocable trusts. Langbein high-lighted problems the revolution might generate and predicted how they might be resolved. Since then, significant problems have indeed developed. First, wills law doctrines designed to effectuate intent of testators have not been universally extended to non-probate transfers. Second, the fragmentation of the wealth transmission process has …

Pay For Play: The Compensated Leisure Flaw Of Contract Damages, Mitchell L. Engler

Articles

Contract damages aim to leave the injured party in as good a position as if the contract had been fulfilled. But discharged laborers often obtain a much better result due to the lack of a reduction for their excused work effort on breach. After first exposing the problematic ramifications of this unjustified deviation, this Article then provides two workable corrections.

Expired Patents, Saurabh Vishnubhakat

Faculty Scholarship

This article presents a comprehensive empirical description of the public domain of technologies that have recently passed out of patent protection. From a new dataset of over 300,000 patents that expired during 2008–2012, the study examines technological, geographical, and procedural traits of newly public inventions as a basis for exploring the social value associated with their competitive use. Moreover, comparing these inventions to inventions newly patented during the same period enables more specific discussion of how the balance of innovation in the United States continues to change.
