An investigation into system security requirements and implementation in an Application Service Provider (ASP) environment
(Galway-Mayo Institute of Technology, 2006)Although the ASP model has been around for over a decade, it has not achieved the expected high level of market uptake. This research project examines the past and present state of ASP adoption and identifies security as ... -
An investigation into the detection and identification of OsHV-1 μvar virus and associated risk factors causing mortalities in Crassostrea gigas in Ireland.
(Galway-Mayo Institute of Technology, 2014)Part two of this study investigated the detection of OsHV-1 μvar and associated risk factors during mortality outbreaks. An epidemiological study was conducted during 2011. 17 bays from around the Irish Coast were selected, ... -
Investigation into the early life history of the European flounder (Platichthys flesus L.) with special emphasis in Galway Bay, Irish West Coast
(Galway-Mayo Institute of Technology, 2012)European flounder (Platichthys flesus L.) economic value is estimated to be worth over 68 million to the Irish economy (mainly from recreational angling activities). Despite such large species value, there is a considerable ... -
Investigation of multiwavelength correlations for the VHE gamma-ray blazar markarian 421 from 1995 to 2009
(Galway-Mayo Institute of Technology, 2011)The blazar Markarian 421 is an excellent laboratory for studying the physical processes within the jets of active galactic nuclei. In this thesis, a multiwavelength database has been compiled using data from the Whipple ... -
Investigation of the substrate specificity of glutamyl endopeptidase using casein substrates
(Galway-Mayo Institute of Technology, 2011)Electrophoretically and chromatographically pure P-casein was prepared from acid caseinate exploiting the differential solubility of different caseins in the presence of Ca2+ at 4°C and 30°C. The yield of P-casein was ... -
Ireland’s understudied flatfish: reproduction, age and growth of the dab Limanda limanda (L.) in Irish coastal waters
(Galway-Mayo Institute of Technology, 2012)In Ireland, although flatfish form a valuable fishery, little is known about the smallest, the dab Limanda limanda. In this study, a variety of parameters of reproductive development, including ovarian phase description, ... -

A molecular approach to the study of a mussel hybrid zone on the west coast of Ireland
(Galway-Mayo Institute of Technology, 2005)The shores of the northwestern Atlantic have two indigenous mussel species, the Blue mussel, Mytilus edulis and the Mediterranean mussel, Mytilus galloprovincialis. These two species once isolated by the last ice age, are ... -
Monitoring intertidal community change in a warming world
(Galway-Mayo Institute of Technology, 2004)If the earth’s climate is warming as predicted, the effects of this environmental change may begin to appear along a range of biological scales, including ecosystems, communities, populations and individual species. The ... -
Nutritional composition, quality and spoilage capacity of orange roughy (Hoplostethus atlanticus) from the North East Atlantic
(Galway-Mayo Institute of Technology, 2008)The nutritional composition o f orange roughy (collected from the Northeast Atlantic near the Rockall Trough) was studied on a seasonal basis. In addition samples were aged and stability assessed. Protein levels (16.68-16.21% ... -
On the ecology of rorqual whales (Balaenopteridae) in Irish waters using intrinsic markers
(Galway-Mayo Institute of Technology, 2012)Despite repeated calls for an ecosystem-based approach to the management of marine resources, little information exists on the ecosystem role and requirements of top predators such as baleen whales in Irish waters. Considering ... -
A phytochemical study of ilex and betula species
(Galway-Mayo Institute of Technology, 1999)A phytochemical study of the outer bark of native common holly (Ilex aquifolium), led to the isolation and identification of nine novel fatty acid esters of the pentacyclic triterpene a-amyrin. These compounds were the ... -
Phytoplankton precision trials in the enumeration and identification of marine microalgae through the scheme “Biological Effects Quality Assurance in Monitoring Programmes (BEQUALM)”.
(Galway-Mayo Institute of Technology, 2010)Scientists are coming under increased pressure in recent years to show that results they obtain arising from their scientific work are quality assured and stand up to scrutiny by independent expert auditors. This has meant ... -
Population Differentiation in Blue Whiting (Micromesistius poutassou) in the North East Atlantic Ocean
(Galway-Mayo Institute of Technology, 2005)Blue whiting is a commercially important gadoid fish found throughout the Atlantic Ocean and the Mediterranean. It is a pelagic, migratory species with feeding grounds in the Norwegian Sea and in the Bay of Biscay. The ... -
Population dynamics of 0-group flounder (Platichthys flesus L.) in Galway Bay, West of Ireland and the value of flounder from shore angling tourism in Ireland
(Galway-Mayo Institute of Technology, 2007)The economic value of flounder from shore angling around Ireland was assessed. Flounder catches from shore angling tournaments around Ireland were related to domestic and overseas shore angling expenditure in order to ... -
