A solid state acoustic variable time delay line Patent

Development and characteristics of solid state acoustic variable time delay line using direct current voltage and radio frequency pulse

Solid state variable time delay

Variable time delay line does not require use of a magnetic field to control a time delay, and can both amplify and delay a signal. Device is inexpensive and space saving, it does not require mecanically moving components, eliminating detrimental vibrations in a sensitive environment

Do social networking groups support online petitions?

This article is the post-print version of the final paper that has been accepted for publication and is forthcoming in Transforming Government: People, Process and Policy. Copyright @ Emerald Group Publishing LimitedEPetitioning has been emerging as arguably the most important eParticipation institutional activity. This paper aims to provide some insights into how ePetitions are perceived and supported by social networking sites. The connection between the UK government’s ePetitioning system and social networking groups linking to governmental petitions was investigated. Online data from Facebook were collected and analysed with respect to numbers of supporters compared to official signatures. The results indicate that although the process of signing an official petition is not more complex than joining a Facebook group, the membership of respective Facebook groups can be much higher. In particular, certain topics experienced very high support on Facebook which did not convert to signatures. The paper raises interesting questions about the potential uptake of citizen-government interactions in policy making mechanisms.The online research tool used for data collection in this paper was developed by Steven Sams who acknowledges support by the World Class University (WCU) program through the National Research Foundation of Korea.

Pathways for Nutrient Loss to Water; Slurry and Fertilizer Spreading

End of project reportThere are almost 150,000 farms in Ireland and these contribute substantial quantities of N and P to inland and coastal waters. Some of these nutrients are carried from wet soils by overland flow and by leaching from dry soils. Farm practice can reduce the loss from farms by judicious management of nutrients. Improvements are required to diminish export of nutrients without impairing operations on the farm. Literature regarding nutrient loss from agriculture was reviewed in this project and maps were prepared to predict best slurry spreading times around Ireland. Two further maps were prepared to show slurry storage requirement on farms
