3D Growth Substrates in Mammalian Cell Culture in Vitro, their Effects on Cellular Function and Response

Mahmoud Gargotti
Three-dimensional (3D) cell culture systems have gained increasing interest in drug discovery and tissue engineering due to a number of advantages in providing more physiologically relevant information and potentially more predictive data for in vivo tests. Extracellular matrix (ECM) proteins have been developed over in recent years to simulate a natural microenvironment for cells cultured in vitro. Conventional cell culture or 2D cell culture form monolayers of cells on a solid surface, which is typically...

Multivariate Statistical Methodologies used in In-vitro Raman Spectroscopy: Simulations and Applications for Drug and Nanoparticle Interactions

Mark Edward Keating
Raman spectroscopy is a growing technology in the fields of in-vitro drug and nanoparticle screening. The label free capability provided by vibrational spectroscopy, as well as the ability of the technique to probe the chemical nature of samples, makes it a good candidate for use in these fields. Crucial to the progress of these methods is the development and validation of robust and accurate multivariate statistical analysis protocols. In this thesis, both established and novel...

An Examination of the Smote and Other Smote-based Techniques That Use Synthetic Data to Oversample the Minority Class in the Context of Credit-Card Fraud Classification

Eduardo Parkinson de Castro
This research project seeks to investigate some of the different sampling techniques that generate and use synthetic data to oversample the minority class as a means of handling the imbalanced distribution between non-fraudulent (majority class) and fraudulent (minority class) classes in a credit-card fraud dataset. The purpose of the research project is to assess the effectiveness of these techniques in the context of fraud detection which is a highly imbalanced and cost-sensitive dataset. Machine learning...

Essays in Energy Economics and Policy

Michael Chesser
The world is currently going through an ‘Energy Transition’ and it is changing how our economies, culture and society operate. The research presented in this thesis emanates from large scale changes and is investigated through three distinct research papers, with separate but interlinked themes. Research paper 1 (Chapter 2) profiles households that have adopted of micro renewable energy systems (micro-RES) and examines whether micro-RES installations have impacted energy consumption based on data from the Irish...

Mechanisms Driving Digital New Venture Creation & Performance: An Insider Action Research Study of Pure Digital Entrepreneurship in EdTech

Kisito Futonge Nzembayie
Digitisation has ushered in a new era of value creation where cross border data flows generate more economic value than traditional flows of goods. The powerful new combination of digital and traditional forms of innovation has seen several new industries branded with a ‘tech’ suffix. In the education technology sector (EdTech), which is the industry context of this research, digitisation is driving double-digit growth into a projected $240 billion industry by 2021. Yet, despite its...

SYMMETRY AND REDUCTIONS OF INTEGRABLE DYNAMICAL SYSTEMS: PEAKON AND THE TODA CHAIN SYSTEMS

Vladimir Gerdjikov
We are analyzing several types of dynamical systems which are both integrable and important for physical applications. The first type are the so-called peakon systems that appear in the singular solutions of the Camassa-Holm equation describing special types of water waves. The second type are Toda chain systems, that describe molecule interactions. Their complexifications model soliton interactions in the adiabatic approximation. We analyze the algebraic aspects of the Toda chains and describe their real Hamiltonian...

Our Reliance on Family for Housing Support Won’t last Forever

Lorcan Sirr
History is more important than geography in explaining our relationship with housing. We have a funny relationship with housing in Ireland, one that goes beyond the usual explanation of our land and property obsession being a post-colonial hang-up. Given our location at the northwest edge of Europe, it would be logical to assume Ireland would have a similar approach to housing as Germany, France and the Netherlands. We are different from our regional neighbours, however,...

Environment Department Doesn’t Have a Clue on Housing

Lorcan Sirr
Over the past two years Sherlock Holmes’s evil foe Professor Moriarty has been wandering the corridors of the Department of the Environment, Community and Local Government, wreaking sublime havoc and leaving several reputation-damaging debacles in his wake. The damage has been so bad that in late 2014 an internal review was carried out. Released to RTE under freedom of information laws, the report was critical of the housing capabilities and activities of the department. Given...

To Solve Housing Crisis, we Must get over our Problem With Cities

Lorcan Sirr
Housing is a many-headed beast with elements of technology, planning, finance, sociology and of course, politics. At its core, however, it is a simple thing: buildings for people and this is why it’s crucial to keep an eye on our population statistics. Preliminary results fromthe recent census are throwing up some interesting figures, all of which have implications for where we should be focusing our efforts to build housing. The location of our empty houses...

Want to end Rental Bias? Start Building More Social Housing.

Lorcan Sirr
When the rent supplement was introduced in 1977 for people in financial need within the private rented sector, the intention was that it would be temporary. Almost 40 years on, it is stillwith us.

Stumbling Block of Social Housing Stalls O’Devaney Gardens

Lorcan Sirr
Last week, Dublin city council (DCC) resolved a dispute with its own councillors over the regeneration of O’Devaney Gardens, a council estate behind Arbour Hill in Dublin. Named after Bishop O’Devaney, who was hanged at Arbour Hill in 1612 as a friend of Tyrone rebel chief Hugh O’Neill, O’Devaney Gardens is a 1950s corporation-built estate of 300 flats in 12 (originally 13) blocks.

That’s Enough Talking, Let’s Have a Proper Plan for Housing

Lorcan Sirr
On March 31 acting environment minister Alan Kelly assembled the third housing and homeless forum in two years. It brought together housing NGOs, Nama, local authorities and bodies such as the Central Bank and Construction Industry Federation, as well as TDs from all political parties. The forum was interesting for a few reasons. First, the issues facing housing haven’t changed in the past 24 months. If anything, they’ve intensified, but the underlying problems remain the...

Let’s Look to UK to Solve Problems of our Ageing Population

Lorcan Sirr
Europe is going grey, very grey. In 1800 no country had a life expectancy beyond age 40, but by 2050 one in three people in Europe will be over 60. By then, one in 10 will be over 80—nearly 500,000 people in Ireland. The ageing population will bring its own problems, caused mainly by health, income and government support. Denmark spends about €5,000 a year on social protection in old age; Latvia, Romania and Croatia...
