Nanotechnology is regarded as one of the key technologies of the future and associated with high expectations by politics, science and economy. Artificially produced nanosized particles and nanoscale system components have new properties which are of importance for the development of new products and applications. Such new properties of materials and substances result from the special properties of surfaces and interfaces and in part, from the geometric shape of the material. In theory nanoparticles (NPs) can be produced from nearly any chemical; however, most NPs that are currently in use today have been made from transition metals, silicon, carbon (single-walled …

Technology-Aided Participative Methods In Environmental Assessment: An International Perspective, Ainhoa Gonzalez, Alan Gilmer, Ronan Foley, John Sweeney, John Fry

Articles

Provisions for citizen involvement in the assessment of potential environmental effects of certain plans, programmes and projects are present in current legislation. An international survey revealed that public participation is common practice in European and some other countries worldwide. However, a number of issues are observed to affect public involvement in EIA/SEA processes and expert opinion differs when evaluating the effectiveness of existing participative methods. Results suggest that technology-aided methods can improve traditional participation processes. In particular, GIS has the potential to increase community knowledge and enhance involvement by communicating information more effectively. Variable accessibility to technology and data quality …

Development Of A Novel Modular Mid-Infrared Sensor For The In-Situ Detection Of The Btex Compounds In Water, Raymond Mccue

Doctoral

This research thesis describes the design, construction and testing of a novel modular mid-infrared fibre optic sensing system for the detection of hydrocarbons in water. It is the adverse effects to these hydrocarbon pollutants on flora and fauna that has led to the development of sensing systems for their detection and quantification. The key sensor design feature, its modularity, utilises simple low cost commercially available optical components, which are inherently suited to construct compact rugged sensing systems to perform in-situ measurements which are ideally preferred for environmental sensing. The various laboratory-based prototypes constructed weee calibrated for two target analytes over …

A Critical Appraisal Of The Opportunities Currently Available For A More Energy Conscious Approach To Residential Building In Ireland, John Mcdonagh, Louis Gunnigan Jan 2006

A Critical Appraisal Of The Opportunities Currently Available For A More Energy Conscious Approach To Residential Building In Ireland, John Mcdonagh, Louis Gunnigan

Conference papers

This paper focuses on the particular advantages which off-site housing construction has over the more traditional methods of building especially where the efficient use and conservation of energy is concerned. It will explain why modern innovative methods of house construction not only have a clear advantage environmentally (big reductions in CO2 emissions) but also deliver substantial benefits to the end user or householder especially in the form of lower energy bills.

The ecological argument for off-site systems is a very powerful one but on its own is still unlikely to be the prime driver for widespread implementation. That growth is …

Point Of Care Healthcare Quality Control For Patients Using Mobile Devices, Owen Lynch

Masters

The advances made in the domain of mobile telecommunications over the last decade offer great potential for developments in many areas. One such area that can benefit from mobile communications is telemedicine, which is the provision of medical assistance, in one form or another, to patients who are geographically separated from the healthcare provider. When a person is ill, individual attention from medical professionals is of the utmost importance until they have returned to full health. However, people who suffer with long term and chronic illnesses may need life long care and often must manage their condition at home. Many …

Evaluating The Use Of In Vitro Bioassays For The Ecotoxicological Assessment Of Irish Estuarine Sediments, Sharon Ni Shuilleabhain

Doctoral

Sediments, as a repository for persistent anthropogenic contaminants, have the potential to cause deleterious effects in the aquatic environment. Particular attention to the quality of sediment is, therefore, warranted in the ecotoxicological risk assessment of aquatic systems. An assessment methodology combining chemical, ecotoxicological and ecological evaluations in a hierarchial test strategy, where toxicological significant and complexity increases with the tiers, is recommended for a thorough appraisal of sediment toxicity. The aim of the present study was to assess the potential of in vitro bioassays to be employed as screening tools got Tier 1 ecotoxicity evaluation of Irish estuarine sediments. Chemical …

Chp And Energy Conservation, Jim Mcgovern Sep 1995

Chp And Energy Conservation, Jim Mcgovern

Articles

The principles of the use of 'combined heat and power' (CHP) for the achievement of fuel energy conservation, minimisation of environmental impact and economic advantage are explained. A distinction is made between the two types of outputs: heat and work. It is argued that an efficiency value that is defined as the sum of the heat and work outputs divided by the energy of the fuel used is not very meaningful. An alternative, rational, efficiency is explained. It is concluded that CHP is an option to be considered where both heating and power are required, but is not a general …
