Effect Of Fracture Heterogeneity On Proppant Transport And Settling Mechanism, Dhurgham Abdulameer Kadhim Jan 2017

Effect Of Fracture Heterogeneity On Proppant Transport And Settling Mechanism, Dhurgham Abdulameer Kadhim

Masters Theses

"Proppant transport modeling through fractures with slickwater fluid systems assumes uniform and homogeneous fracture widths by implying constant fluid behavior at wall boundaries. Hydraulic fracturing mineback operations have demonstrated that induced fractures are heterogeneous and varying in width. This work investigates the impact of fracture width heterogeneity, roughness, and leak-off on ceramic proppant transport and settling, using proppant distribution concepts of Equilibrium Dune Level (EDL) and equilibrium Dune Length (EDX). Experimental work was conducted to investigate the impact of fracture width heterogeneity by varying fracture width along two plexiglass sheets. To mimic actual hydraulic fractures, the injection side was designed …

A Replication Study: 20 Years Later Correctional Officers: How Do They Perceive Sexual Offenders?, Kimberlie Massnick

Theses and Dissertations

Correctional officers represent a large, influential group working within the criminal justice system; as such they have long attracted the interest of social scientists. These professionals, their attitudes towards inmates and the impact of these attitudes, have received scrutiny, especially since Zimbardo’s (1973) study of a mock prison, commonly referred to as the Stanford Prison Experiment. When compared to other professionals within the criminal justice system, correctional officers are often the least empathic, the most punitive, and the least supportive of rehabilitation. These potential attitudes this is unfortunate since correctional officers are ideally placed to improve the social atmosphere of …

On The Precipice: Prospects For Free Labor Unions In Vietnam, Tran Thi Kieu Trang, Richard Bales

San Diego International Law Journal

Vietnam (officially, the “Socialist Republic of Vietnam”) is rapidly transitioning economically, in large part due to pro-trade policies that have attracted international capital. A necessary component for Vietnam to further integrate into the world economy is to develop a system of industrial relations that will ensure industrial stability and reassure international manufacturers that there is no risk of embarrassment resulting from revelations of brutal or unsafe working conditions. Positive signs for rapid labor reform were visible as recently as early 2016 with the Trans-Pacific Partnership (“TPP”), a trade agreement intended to integrate trade among twelve countries (including Vietnam), which would …


Physician-Assisted Suicide: Removing Residency Requirements In The U.S. To Comport With An International Right To Health, Alexi Silverman Jan 2017

Physician-Assisted Suicide: Removing Residency Requirements In The U.S. To Comport With An International Right To Health, Alexi Silverman

San Diego International Law Journal

In 1948, the UN General Assembly passed a resolution, known as the International Bill of Human Rights. The Bill contains the Universal Declaration of Human Rights, articulating a human right to health. A subsequent treaty, the International Covenant on Civil and Political Rights states that “every human being has the inherent right to life.” Furthermore, the International Covenant on Economic, Social and Cultural Rights protects access to healthcare. However, these treaties do not explicitly recognize a “right to die,” leaving the decision of whether to allow euthanasia and physician-assisted suicide within the discretion of individual countries.

With this international background …
