An Iona of the East : the early-medieval monastery at Portmahomack, Tarbat Ness

A new research programme located on the Tarbat peninsula in north-east Scotland offers the first large-scale exposure of a monastery in the land of the Picts. A case is argued that the settlement at Portmahomack was founded in the 6th century, possibly by Columba himself, and by the 8th century had developed into an important political and industrial centre comparable with Iona. Signs of the monastery's former prominence survive in workshops producing liturgical objects, possibly including books, and in the brilliant art of the Tarbat cross-slabs at Portmahomack, Nigg, Shandwick and Hilton of Cadboll. The monastic institution, which had contacts with Northumbria and beyond, seems to have been expunged by the 11th century, probably in the context of political struggles between Scandinavian, Pictish and Scottish interests

Gravitational Waves in G4v

Gravitational coupling of the propagation four-vectors of matter wave functions is formulated in flat space-time. Coupling at the momentum level rather than at the "force-law" level greatly simplifies many calculations. This locally Lorentz-invariant approach (G4v) treats electromagnetic and gravitational coupling on an equal footing. Classical mechanics emerges from the incoherent aggregation of matter wave functions. The theory reproduces, to first order beyond Newton, the standard GR results for Gravity-Probe B, deflection of light by massive bodies, precession of orbits, gravitational red shift, and total gravitational-wave energy radiated by a circular binary system. Its predictions of total radiated energy from highly eccentric Kepler systems are slightly larger than those of similar GR treatments. G4v predictions differ markedly from those of GR for the gravitational-wave radiation patterns from rotating massive systems, and for the LIGO antenna pattern. The predicted antenna patterns have been shown to be highly distinguishable in the case of continuous gravitational-wave sources, and should therefore be testable as data from Advanced LIGO becomes available over the next few years.Comment: 37 pages, 14 figure

Phenotypic Expression of Two Candidate Genes of Nonsyndromic Craniosynostosis in Danio rerio

Phenotypic Expression of Two Candidate Genes of Nonsyndromic Craniosynostosis in Danio rerio Annemarie Carver, Dept. of Biology with Dr. Rita Shiang, Dept. of Human and Molecular Genetics Craniosynostosis, the premature fusion of cranial sutures, can be either syndromic or nonsyndromic. The majority of cases are nonsyndromic, the causes of which are rarely known. Craniosynostosis is relatively common and occurs in about 1 in every 2,000 babies. Bambia is suspected to cause craniosynostosis as a predicted deleterious stabilizing variant has been identified in affected individuals within one family, though when normally or under expressed no phenotypic differences are observed. Slc30a9, a gene involved in zinc transport within cells,is also suspected to cause craniosynostosis as a predicted pathogenic variant was also identified in the same family, the variant is predicted to replace a leucine with proline. It is hypothesized that when the gene bambiais overexpressed or the null slc30a9 mutant gene is present in Danio rerio, phenotypic characteristics of craniosynostosis will be observed when compared to wildtype animals. The purpose of this study is to determine whether a phenotypic difference occurs in the development of the skull when the gene bambia is overexpressed or when slc30a9 is mutated in D. rerio, zebrafish. Wholemount in situ hybridization and observation of 8 weeks of skull development of zebrafish were performed to test this hypothesis. The results of this study could be used to identify causes for nonsyndromic craniosynostosis and help to learn more about the condition.https://scholarscompass.vcu.edu/uresposters/1302/thumbnail.jp

Collective electrodynamics I

Standard results of electromagnetic theory are derived from the direct interaction of macroscopic quantum systems; the only assumptions used are the Einstein-deBroglie relations, the discrete nature of charge, the Green's function for the vector potential, and the continuity of the wave function. No reference is needed to Maxwell's equations or to traditional quantum formalism. Correspondence limits based on classical mechanics are shown to be inappropriate

Trouble\u27s Clarion Call for Leaders: Jo Ann Robinson and the Montgomery Bus Boycott

Turbulent times are part of the human experience. They provide what Useem calls the leadership moment when one is given the opportunity to define who one is (1998). For Jo Ann Robinson, that leadership moment came personally in 1949, and publicly in 1955 when she transformed her trauma into a pro-social action of change (Williams and Allen, 2015). This article is a historical narrative inquiry into the life of Robinson who launched the Montgomery boycott and helped start the civil rights movement. The article tells the rest of the story beyond Parks and King, and explores the question: How did Robinson lead? With no authority, she empowered more than 50,000 African American to stand up and change their world

Working with graphic design students to promote `Land of Lost Content¿ at Leeds Met.

yesAs Leeds Metropolitan is a university of festivals and partnerships, the library was given the opportunity this year to host a festival to promote the library and all its services to the university. The library festival was a week of events and activities to promote the library and its space in new ways. It was a good way to remind staff and students of the value of libraries, not only as places to learn but also as places to enhance our leisure and working lives ... we chose to promote the database `Land of Lost Content¿. This was because graphic design and art students are based at our campus and we also thought this database would attract a wide range of students who might otherwise think that electronic databases contain little of interest for them. Our promotion has been so successful in many ways that we would like to share our experience with other librarians

A notation for designing restoring logic circuitry in CMOS

We introduce a programming notation in which every syntactically correct program specifies a restoring logic component, i.e., a component whose outputs are permanently connected, via "not too many" transistors, to the power supply. It is shown how the specified components can be translated into transistor diagrams for CMOS integrated circuits. As these components are designed as strict hierarchies, it is hoped that the translation of the transistor diagrams into layouts for integrated circuits can be accomplished mechanically

Using GIS to Explore the Technical and Social Aspects of Site Selection for Radioactive Waste Disposal Facilities

This working paper reviews the current situation regarding radioactive waste disposal in the UK and questions the pursuance of a purely engineering approach to gaining public support. Past histories concerning the siting of nuclear industry facilities; power stations and latterly, waste repositories, are briefly discussed and used to demonstrate that more attention needs to be paid to the geographical and social science if current proposlas for a rock laboratory, and ultimately and operational repository, at Longlands Farm near Sellafield are to succeed. The usefulness of Geographical Information Systems (GIS) and associated spatial information technologies are highlighted. Suggestions are made as to how these may be made available for public use via the Internet in adopting a more open approach to public information, consultation and participation
