The Geography of Revolution: The case of Longford, 1917-1921

Why were some areas of the Ireland more active than others during the War of Independence, and why did the areas of most activity change over the course of the war between 1919 and 1921? In the context of the Irish midlands, County Longford stands out as one of the most violent counties surrounded by areas where there was much less activity by the IRA. Even within the county there was a significant difference in the strength of republican activity between north and south Longford. This article will examine the factors that were responsible for the strength of the IRA campaign in this midland enclave, including socio-economic conditions, administrative decisions and failures, and the contemporary political context.
Much of the evidence upon which the paper is based comes from applications made by Longford Volunteers for military service pensions, granted to veterans of the campaign by the Irish government after 1924. Many of these documents are soon to be released by the Irish government. The paper will also include a discussion of these sources and the way in which they can be used by historians to advance our understanding of Ireland’s revolutionary decade.

'Off-On' Fluorescent Sensors for Physiological levels of Magnesium Ions based on Photoinduced Electron Transfer (PET) which also behave as OR Logic Gates

The fluorescence of molecules 1-3 is enhanced by factors of up to 67 in the presence of magnesium and calcium ions in neutral water which allows the selective monitoring of magnesium ions under simulated physiological conditions and permits the construction of truth tables with OR logic when these molecules are viewed as ion input-photon output molecuIar devices.

Tailoring Plasmonic Metamaterials for Ultrasenstive Detection of Mercury Trace Contaminants via Molecular Logic Gates

Structural and functional information encoded in DNA combined with unique properties of nanomaterials could be of use for the construction of novel biocomputational circuits and intelligent biomedical nanodevices. However, at present their practical applications are still limited by either low reproducibility of fabrication, modest sensitivity, or complicated handling procedures. Here, we demonstrate the construction of label-free and switchable molecular logic gates (AND, INHIBIT, and OR) that use specific conformation modulation of a guanine- and thymine-rich DNA, while the optical readout is enabled by the tunable metamaterials which serve as a substrate for surface enhanced Raman spectroscopy (MetaSERS). Our MetaSERS-based DNA logic is simple to operate, highly reproducible, and can be stimulated by ultra-low concentration of the external inputs, enabling an extremely sensitive detection of mercury ions down to 2×10-4 ppb, which is four orders of magnitude lower than the exposure limit allowed by United States Environmental Protection Agency

Violence against women in the Irish War of Independence, 1919-1921

This chapter examines the nature and extent of violence experienced by women in Ireland during the Irish War of Independence (1919-1921) at the hands of both the Crown forces and the Irish Republican Army. It argues that targetted killings of women by either side was rare. The most common forms of such violence can be categorised as physical, gendered (cutting of hair) and psychological (intimidation and the killing of male relatives). It argues that there was a difference between gendered and sexual crime, the latter of which appears to have been very uncommon. A considerable part of the chapter uses theoretical literature on violence against women in conflict zones to explain why sexual violence was uncommon, arguing that neither side had much to gain from its employment, that the Crown forces were aware of the damage it could do to Britain's international reputation and that the terror tactics adopted by the Crown forces were sufficient to achieve their ends without resorting to rape. In regard to the IRA, the absence of any evidence of rape or sexual assault being perpetrated could be attributable to their Catholicism, reliance on support from the community, the efforts of the first Dáil to achieve foreign recognition of the Republic and the role of Cumann na mBan women in the guerrilla conflict. The historiography of women in the Irish revolution is also analysed.
