Engineering Characteristics Of Compacted Sand-Bentonite Mixtures, Ali Faisal Ghazi

Theses: Doctorates and Masters

Sand-clay mixtures are commonly used as a liner/barrier material in various engineering applications, such as construction of hydraulic and waste containments. Permeability, compressibility and strength are important properties of sand-clay mixtures and are often required for the design of the liner/barrier of the containments.

In states like Western Australia, which is covered mostly by sandy soils, engineers face difficulties with economically sourcing clays for liner/barrier applications. Any reliable research finding that recommends an optimum clay content to be used with sandy soil can be of significant importance. Such findings for the local Perth sandy soil are rarely available in the …

Professional Formation Of Engineers: Enhancing The First Year Student Experience, Eileen Goold

Conference Papers

This paper reports on a study investigating engineering students’ perceptions of engineering practice and whether engineering students’ cognitive engagement benefits from bridging the gap between the technical issues in their education and the practical realities of modern engineering practice.

Engineering Students’ Perceptions Of Their Preparation For Engineering Practice, Eileen Goold Dr

Conference Papers

A common theme in the scholarly literature describing engineering is associated with the conception of the term global engineer where the role of the engineer has become quite broad. This study investigates engineering students’ perceptions of their future careers and their preparation for professional practice. This is important information for engineering educators as students with heightened interest in professional practice demonstrate more cognitive engagement. Additionally many graduate engineers are challenged by the transition into engineering practice. A mixed methods approach is employed. The degree competencies are required and learned by electronic engineering students, at the Institute of Technology Tallaght Dublin, …

A Critical Realist Approach To Engineering Ethics, Eddie Conlon

Conference papers

This paper is focused on the teaching of engineering ethics (EE). Through a focus on safety and the lens of what sociologists call the agency/ structure relationship it examimes various approaches to this teaching. Drawing on Critical Realism it argues there are deficiencies in both the dominant approach and a number of proposed alternatives as they suffer from various forms of conflationism . By drawing on Critical Realism (CR) a more robust agenda for teaching engineering ethics can be developed. It is argued that CR offers a basis for understanding the range of factors which lead to accidents and disasters. …

Atmospheric Cold Plasma As A Tool For Microbiological Control, Dana Ziuzina

Doctoral

Outbreaks of foodborne human illnesses resulting from contaminated raw or minimally processed fruits and vegetables have been widely reported globally. The microbiological challenges associated with fresh produce are diverse and respond differently to minimal processing technologies. Atmospheric cold plasma is a relatively new technology and represents a potential alternative to traditional methods for decontamination of foods. The objective of this work was to determine the influence of extrinsic atmospheric cold plasma (ACP) treatment control parameters and to optimize treatment parameters for decontamination with respect to different forms of key safety challenges pertinent to fresh produce.

The optimisation studies demonstrated that …

An Analysis Of The Impact Of Playout Delay Adjustments Introduced By Voip Jitter Buffers On Listening Speech Quality, Peter Počta, Hugh Melvin, Andrew Hines

Articles

This paper investigates the impact of frequent and small playout delay adjustments (time-shifting) of 30 ms or less introduced to silence periods by Voice over IP (VoIP) jitter buffer strategies on listening quality perceived by the end user. In particular, the quality impact is assessed using both a subjective method (quality scores obtained from subjective listening test) and an objective method based on perceptual modelling. Two different objective methods are used, PESQ (Perceptual Evaluation of Speech Quality, ITU-T Recommendation P.862) and POLQA (Perceptual Objective Listening Quality Assessment, ITU-T Recommendation P.863). Moreover, the relative accuracy of both objective models is assessed …

Medical Versus Surgical Methods Of Early Abortion: Protocol For A Systematic Review And Environmental Scan Of Patient Decision Aids, Kyla Z. Donnelly, Rachel Thompson

Dartmouth Scholarship

Introduction: Currently, we lack understanding of the content, quality and impact of patient decision aids to support decision-making between medical and surgical methods of early abortion. We plan to undertake a systematic review of peer-reviewed literature to identify, appraise and describe the impact of early abortion method decision aids evaluated quantitatively (Part I), and an environmental scan to identify and appraise other early abortion method decision aids developed in the US (Part II).

Methods and analysis: For the systematic review, we will search PubMed, Cochrane Library, CINAHL, EMBASE and PsycINFO databases for articles describing experimental and observational studies evaluating …

Reorienting Restorative Justice: Initiating A New Dialogue Of Rights Consciousness, Community Empowerment And Politicization, Thalia Gonzalez

Faculty Scholarship

For the last three decades scholars have explored the practice of restorative justice as a crime control mechanism in a multitude of settings. Much of the discourse has focused on restorative justice as an alternative to traditional punitive and retributive criminal justice processes. Whether restorative or punitive, criminal justice processes that seek to address harm are not apart, above, or outside social, cultural and political relations. This Article seeks to initiate a new dialogue of justice and argues that the ontology of restorative justice should to be viewed to include a liberatory moment of politicization focused on promoting equality and …

Hiv Prevalence In Blood Donors And Recipients In Pakistan: A Meta-Analysis And Analysis Of Blood-Bank Data, Bushra Moiz, Barkat Ali, Muhammad Hasnain Chatha, Ahmed Raheem, Hasan Abbas Zaheer

Department of Pathology and Laboratory Medicine

Background:
The first instances of HIV-antibody detection in donated blood in Pakistan were reported in 1988. Since then, documentation of HIV in blood donors and of rates of transmission via transfusion has been limited. Previously assumed to have a low prevalence, HIV is an increasing health concern in Pakistan. Since there is no national, centralized blood-banking system, there are no reliable data on which to base estimated risks of transfusion-associated HIV infection. This study was therefore conducted to estimate the prevalence of HIV in blood donors and recipients in Pakistan between 1988 and 2012.
Methods:
Meta-analyses were undertaken of reported …

Planning For Digitization Of University Libraries In Ghana: Challenges And Prospects, Perpetua Sekyiwa Dadzie, Thomas Van Der Walt

Library Philosophy and Practice (e-journal)

The study investigates the availability of strategic plans or policies for the development of digital libraries in selected universities in Ghana. A case study approach was adopted and interviews were held with three university librarians to determine their views on planning and budgeting for digitization. The findings reveal that all three university libraries have strategic plans, though some are outdated and therefore, rely on policies to ensure that digitization activities are enhanced. Budgetary support for digitization activities range from 16.6% - 50% of the total library budget. The study recommends that the libraries should have an up-to-date strategic plan which …
