Numerical Solution Of Linear Integro-Ordinary Differential Equations Using Taylor Series, Muna M. Mustafa

Baghdad Science Journal

Taylor series is applied to treat two types of higher order linear integro-ordinary differential equations: linear Fredholm and Volterra integro-ordinary differential. In this technique Taylor series is substituted for the unknown function after differentiating both sides of linear integro-ordinary differential equation with respect to x. The required derivatives and the involved integrals have been approximated using central differences and quadrature rules respectively. The resulting algebraic equations are solved by Gauss elimination technique. Program is written in MATLAB language and examples are presented to illustrate the results of this method.

Survival Of Patients Treated With Intra-Aortic Balloon Counterpulsation At A Tertiary Care Center In Pakistan - Patient Characteristics And Predictors Of In-Hospital Mortality., Fahim H. Jafary, Sohail A. Khan, Haresh Kumar, Numaan F. Malik, K. Kazmi, Sajid Dhakam, Azam Shafquat, Aamir Hameed, Javed Tai, Najaf Nadeem

Department of Medicine

BACKGROUND: Intra-aortic balloon counterpulsation (IABC) has an established role in the treatment of patients presenting with critical cardiac illnesses, including cardiogenic shock, refractory ischemia and for prophylaxis and treatment of complications of percutaneous coronary interventions (PCI). Patients requiring IABC represent a high-risk subset with an expected high mortality. There are virtually no data on usage patterns as well as outcomes of patients in the Indo-Pakistan subcontinent who require IABC. This is the first report on a sizeable experience with IABC from Pakistan.

METHODS: Hospital charts of 95 patients (mean age 58.8 (+/- 10.4) years; 78.9% male) undergoing IABC between 2000-2002 …

Health Alert: Underreported Medical Errors, Anna H. Gibson

Student Scholarship

Patient medical errors cause thousands of individual injuries and deaths each year. Avoidable medical errors occur every day, thus creating serious concern as to the safety, ethical and legal implications in healthcare delivery. A literature review of scholarly work indicates medical errors are underreported both at the institutional level and on the individual level. This paper attempts to explain why medical errors are underreported. It considers reporting practices from other industries that are applicable to the medical industry, the importance of reporting medical errors along with those incidents that have the potential to improve patient safety and patient quality of …

Corrective Justice, Equal Opportunity, And The Legacy Of Slavery And Jim Crow, David B. Lyons

Faculty Scholarship

Chattel slavery was a brutally cruel, repressive, and exploitative system of racial subjugation. When it was abolished, the former slaveholders owed the freedmen compensation for the terrible wrongs of enslavement. Ex-slaves sought reparations, especially in the form of land, but few received any sort of recompense. The wrongs they suffered were never repaired.

No one alive today can be held accountable for the wrongs of chattel slavery, and those who might now be called upon to pay reparations were not even born until many decades after slavery ended. For some scholars, the lack of accountable parties makes current reparations claims …

Trend And Cycle Analysis Of Unemployment Insurance And The Employment Service, Wayne Vroman, Stephen A. Woodbury

External Papers and Reports

This report traces historical developments in two major DOL programs: State Unemployment Insurance (UI) and the federal-state Employment Service (ES). Developments in the UI program are traced from the late 1940s while ES program activities are traced from the late 1960s. For both programs, the report emphasizes long term trends as well as changes that have occurred over the course of the business cycle. The analysis uses annual data and is conducted at three levels of geographic detail: national, regional and state. A major objective of the project was to create data files useful for other researchers in studying the …

How To Influence States: Socialization And International Human Rights Law, Ryan Goodman, Derek Jinks

Duke Law Journal

Regime design choices in international law turn on empirical claims about how states behave and under what conditions their behavior changes. Substantial empirical evidence suggests three distinct mechanisms whereby states and institutions might influence the behavior of other states: coercion, persuasion, and acculturation. Several structural impediments preclude effective implementation of coercion- and persuasion-based regimes in human rights law--yet these models of social influence inexplicably predominate in international legal studies. In this Article, we first describe in some detail the salient conceptual features of each mechanism of social influence. We then link each of the identified mechanisms to specific regime design …

Crystal Eastman And The Internationalist Beginnings Of American Civil Liberties, John Fabian Witt

Duke Law Journal

The modern American civil liberties movement famously began with the United States's intervention in World War I. Yet these beginnings have long raised a conundrum for civil liberties historians. Why did the American civil liberties movement arise precisely when so many sophisticated legal and political thinkers began to call into question the truth value of abstract rights claims? The puzzling rise of civil liberties in an age of pragmatic skepticism is all the more startling given that early leaders of the civil liberties movement were themselves leading rights skeptics. This Article offers a new interpretation of the rise of the …

Stress Corrosion Cracking And Hydrogen Embrittlement Of Martensitic Alloy Ep-823, Mohammad K. Hossain

UNLV Theses, Dissertations, Professional Papers, and Capstones

This investigation is focused on the evaluation of stress corrosion cracking (SCC), localized corrosion, and hydrogen embrittlement (HE) susceptibility of martensitic Alloy EP-823 in neutral and acidic solutions at ambient and elevated temperatures. While no failures were observed in smooth specimens in the neutral solution, failures were noticed in the 90°C acidic solution at constant-load (CL) leading to a threshold stress (O'_th) of 102 ksi. The presence of a notch reduced the O'_th value to 91 ksi in a similar environment. The ductility (%El and %RA), time-to-failure (TTF), and true failure stress (O'_r) were gradually …
