Rapid chemical test for the identification of chromium-molybdenum steel

This note describes a simple, rapid, qualitative test which can be applied to solutions of drilling or chips for the identification of chromium-molybdenum steel. The test is based on the orange-red compound which is formed when thiocyanate and inequivalent molybdenum react. This test is much more reliable than the potassium ethylxanthate test which has been recommended for a like purpose. A list of the apparatus and reagents which are required, and a description of the procedure follows

Forest cover estimation in Ireland using radar remote sensing: a comparative analysis of forest cover assessment methodologies

Quantification of spatial and temporal changes in forest cover is an essential component of forest monitoring programs. Due to its cloud free capability, Synthetic Aperture Radar (SAR) is an ideal source of information on forest dynamics in countries with near-constant cloud-cover. However, few studies have investigated the use of SAR for forest cover estimation in landscapes with highly sparse and fragmented forest cover. In this study, the potential use of L-band SAR for forest cover estimation in two regions (Longford and Sligo) in Ireland is investigated and compared to forest cover estimates derived from three national (Forestry2010, Prime2, National Forest Inventory), one pan-European (Forest Map 2006) and one global forest cover (Global Forest Change) product. Two machine-learning approaches (Random Forests and Extremely Randomised Trees) are evaluated. Both Random Forests and Extremely Randomised Trees classification accuracies were high (98.1–98.5%), with differences between the two classifiers being minimal (<0.5%). Increasing levels of post classification filtering led to a decrease in estimated forest area and an increase in overall accuracy of SAR-derived forest cover maps. All forest cover products were evaluated using an independent validation dataset. For the Longford region, the highest overall accuracy was recorded with the Forestry2010 dataset (97.42%) whereas in Sligo, highest overall accuracy was obtained for the Prime2 dataset (97.43%), although accuracies of SAR-derived forest maps were comparable. Our findings indicate that spaceborne radar could aid inventories in regions with low levels of forest cover in fragmented landscapes. The reduced accuracies observed for the global and pan-continental forest cover maps in comparison to national and SAR-derived forest maps indicate that caution should be exercised when applying these datasets for national reporting

AN INITIAL EVALUATION OF THE EFFECTIVENESS OF INTREO ACTIVATION REFORMS. ESRI RESEARCH SERIES NUMBER 81 MARCH 2019

This report presents results from an initial evaluation that the Economic and Social Research Institute (ESRI) has undertaken of the effectiveness of the most recent set of activation reforms that have been made to Ireland’s public employment services (PES). The modifications, which are known as the Intreo activation process reforms, were first introduced in 2012 for all newly unemployed Jobseeker’s Allowance (JA) and Jobseeker’s Benefit (JB) recipients only. The reforms have focused on making changes to how benefit and employment services are delivered to jobseekers as opposed to what types of employment services are delivered (i.e., job search assistance, training, education courses, etc.)

Incumbency Advantage in Irish Elections: A Regression Discontinuity Analysis

Ireland provides an interesting setting for the study of incumbency advantage. Its electoral system creates incentives for political candidates to cultivate a loyal, personal following and the rate of incumbent re-election is one of the highest in the world. This paper exploits the quasi-experimental features of the system of proportional representation with a single transferable vote (PR-STV) to estimate incumbency advantage in Ireland’s lower house of parliament. In very close elections, where there is a narrow margin of victory, it is likely that bare winners are comparable in their unobservable characteristics to bare losers. Regression discontinuity design (RDD) identifies the causal effect of incumbency by comparing the subsequent electoral outcomes of bare winners and losers. The analysis indicates that incumbency causes an eighteen percentage point increase in the probability that a candidate is successful in a subsequent election. We show that Ireland’s multi-party, multi-candidate system is particularly suited to the application of the RDD methodology. JEL: C21

Development and characterisation of collagen-based scaffolds for breast cancer research

Collagen is the most abundant component of the extracellular matrix, and therefore represents an ideal platform for culture of a variety of cell types. Collagen has been widely used in 3D culture models for tissue engineering and musculoskeletal-related research. Recently, attempts to extend the use of collagen-based 3D culture models to cancer research have shown promise. While 2D culture presents a useful tool for cancer research, it is ultimately flawed due to poor replication of the tumour microenvironment, the lack of three- dimensional cell-cell/cell-matrix interactions and often exaggerated response to therapeutic agents. 3D models that aim to overcome the issues associated with 2D culture research offer a new frontier for cancer research with cell growth, morphology and genetic properties that more closely match in vivo cancer. The focus of this thesis was to develop 3D collagen- based scaffolds for use in breast cancer research. A range of collagen-based scaffolds were successfully fabricated using a freeze-drying procedure. Scaffolds were highly porous with homogenous pore sizes and an interconnected structure that was suitable for cell infiltration and nutrient/waste exchange. All scaffolds demonstrated appropriate mechanical properties for mimicking cancerous breast tissue stiffness and displayed high in vitro stability with low degradation. Cell line studies demonstrated scaffold biocompatibility with sustained breast cancer cell proliferation over 21 days, with cells fully infiltrating throughout the scaffolds. 3D culture led to an increase in cell malignancy compared to 2D, with MCF7 cells displaying properties of ECM modification, hypoxia and glycolysis. The fabricated scaffolds were successfully applied as an in vitro drug testing model, with cells cultured in the 3D scaffolds displaying increased chemoresistance compared to 2D cultured cells. Overall, this thesis successfully delivered a biologically relevant in vitro culture model that offers significant potential to deliver an increased understanding of breast cancer progression and augment drug discovery

The NCBO OBOF to OWL Mapping

Two of the most significant formats for biomedical ontologies are the Open Biomedical Ontologies Format (OBOF) and the Web Ontology Language (OWL). To make it possible to translate ontologies between these two representation formats, the National Center for Biomedical Ontology (NCBO) has developed a mapping between the OBOF and OWL formats as well as inter-conversion software. The goal was to allow the sharing of tools, ontologies, and associated data between the OBOF and Semantic Web communities.

OBOF does not have a formal grammar, so the NCBO had to capture its intended semantics to map it to OWL.

This official NCBO mapping was used to make all OBO Foundry ontologies available in OWL. 

Availability: This mapping functionality can be embedded into OBO-Edit and Protégé-OWL ontology editors. This software is available at: http://bioontology.org/wiki/index.php/OboInOwl:Main_Pag
