Integration of Audio Resources into a Digital Library: The BEIC Case Study

International Journal of Digital Curation, 2015
The focus of this paper is on the integration of audio resources with other content types in digital libraries. As a case study, we will present the most recent initiative of the Biblioteca Europea di Informazione e Cultura (BEIC), an Italian institution that pursues educational and instructional goals through the realization and management of a ...

Generalized boundary conditions for general relativity for the asymptotically flat case in terms of Ashtekar's variables [PDF]

, 1995
There is a gap that has been left open since the formulation of general relativity in terms of Ashtekar's new variables namely the treatment of asymptotically flat field configurations that are general enough to be able to define the generators of the ...

Lasalocid awareness and sampling in Scotland [PDF]

, 2010
Lasalocid is an ionophore antibiotic extensively used as a coccidiostat in poultry production. Lasalocid should not be fed to egg-laying hens as it accumulates in the eggs, and residues have often been found in eggs. Other ionophores are toxic to humans,

The effectiveness of a Wikimedian in permanent residence: the BEIC case study

JLIS.it, 2018
Since 2015, Fondazione BEIC has continuously worked with a Wikimedian in residence sourced from Wikimedia Italia, showing how activity on Wikimedia projects is an integral part of an institution’s work on online presence. As an update to the Biblioteche oggi article of 2015, where the structure and main outputs of the partnership have been described ...

Remarks on the Reduced Phase Space of (2+1)-Dimensional Gravity on a Torus in the Ashtekar Formulation [PDF]

, 1997
We examine the reduced phase space of the Barbero-Varadarajan solutions of the Ashtekar formulation of (2+1)-dimensional general relativity on a torus.

Hamiltonian dynamics for Einstein's action in G$\rightarrow$0 limit

, 2011
The Hamiltonian analysis for the Einstein's action in $ G\to 0 $ limit is performed. Considering the original configuration space without involve the usual $ADM$ variables we show that the version $ Gto 0 $ for Einstein's action is devoid of physical ...

Ashtekar Formulation of 2+1 Gravity on a Torus

, 1992
Pure (2+1)-dimensional Einstein gravity is analysed in the Ashtekar formulation, when the spatial manifold is a torus. We have found a set of globally defined observables, forming a closed algebra. This allowed us to solve the quantum constraints, and to

Complex Ashtekar variables and reality conditions for Holst's action

, 2011
From the Holst action in terms of complex valued Ashtekar variables additional reality conditions mimicking the linear simplicity constraints of spin foam gravity are found.

Factors affecting ranging behaviour in commercial free-range hens [PDF]

, 2016
Many studies have assessed use of the outdoor ‘range’ area on free-range laying farms, and have revealed that percentage range use at any one time rarely exceeds 50% of the flock, and is sometimes below 10%.
