Who was buried at Stonehenge?
No full textStonehenge continues to surprise us. In this new study of the twentieth-century excavations,
together with the precise radiocarbon dating that is now possible, the authors propose that the
site started life in the early third millennium cal BC as a cremation cemetery within a circle
of upright bluestones. Britain’s most famous monument may therefore have been founded as the
burial place of a leading family, possibly from Wales
Template assisted strain tuning and phase stabilization in epitaxial BiFeO3 thin films
No full textStrain engineering is a key to develop novel properties in functional materials. We report a strain mediated phase stabilization and epitaxial growth of bismuth ferrite(BiFeO3) thin films on LaAlO3 (LAO) substrates. The strain in the epitaxial layer is controlled by controlling the thickness of bottom electrode where the thickness of the BFO is kept constant. The thickness of La0.7Sr0.3MnO3(LSMO) template layer was optimized to grow completely strained tetragonal, tetragonal/rhombohedral mixed phase and fully relaxed rhombohedral phase of BFO layers. The results were confirmed with coupled-θ-2θ scan, and small area reciprocal space mapping. The piezoelectric d33 (˜ 45-48 pm/V) coefficient of the mixed phase was relatively larger than the strained tetragonal and relaxed rhombohedral phase for a given thickness
The imperatives for organizational governance in a large charity: a strategic choice perspective
No full textThis paper explains the factors that shaped governance practices in a large charity. The author uses strategic choice theory in an analysis of case study data to bring into calculation the internal and external factors that impacted the roles of board members and executives. The paper finds overall support for a powersharing model and contributes to our understanding of governance in nonprofit organizations.Phil Sa

Music, History, and the Fugue: The Individual and the Infinite in Leo Tolstoy’s War and Peace
No full textIn Leo Tolstoy’s work War and Peace, the author attempts to write a history while exploring what history is. As Italian writer Nicola Chiaromonte puts it, “The novel was to be not only historical, but about history.” One way through which the reader can see Tolstoy’s understanding of history in this novel is by following the role of art, and in particular, the role of music
Influence of author\u27s birthplace on setting of novels
No full textV diplomskem delu se bom posvetila vprašanju, ali rojstni kraj avtorja vpliva na to, kam avtor postavi dogajanje v svojem romanu. Pri izboru avtorjev sem si pomagala s knjigo 100 slovenskih pripovednikov in spletnim portalom Geopedija. Ker sem želela pisatelje iz različnih delov Slovenije, sem iz vsake regije izbrala tri naključne predstavnike. Avtorje sem razdelila po statističnih regijah Slovenije in prebrala vse njihove romane. Pri Zasavski in Posavski regiji sem našla le enega ali dva avtorja.
Omejila sem se le na romane, saj bi bili celotni opusi vseh avtorjev preobsežni za mojo raziskavo. Upoštevala sem oznake roman v Cobissu, vendar ob upoštevanju, da so oznake tam velikokrat napačne, zato sem za prvi kriterij, ali je delo res roma, upoštevala avtorjevo oznako v podnaslovu.I will get down to question in a dissertation, if birthplace of an author influences this, where an author puts activity in his novel. I helped myself with the book of 100 slovenskih pripovednikov and web portal Geopedija at selection of authors. Because I wanted writers from different parts of Slovenia, I chose three random representatives from every region·. I distributed authors round statistical regions of Slovenia and read through all their novels. I found only one or two author at the Zasavje and Posavje region.
I limited myself only to novels, as entire opera of all authors would be too extensive for my research. Complied with am mark the novel in Cobiss, however bearing in mind, that marks are wrong there several times, I am for first criterion therefore, is it work of really frame, complied with author\u27s mark in subtitle
Towards a fuller, more nuanced narrative of Chalcolithic and Early Bronze Age Britain 2500-1500 BC
No full textThis contribution considers some of the many recent advances in our understanding of Chalcolithic and Bronze Age Britain and uses these to highlight the weak points in our current state of knowledge. Focusing mainly on the period 2500–1500 BC, it concentrates on issues of chronology, human movement, the role of metal and monuments as 'drivers' of action, and the potential offered by current studies of artefact manufacture, use and depositio
A gazetteer and summary of French pottery imported into Scotland c. 1150 to c. 1650 a ceramic contribution to Scotland's economic history Ceramic Resource Disc 3
No full textThe proposal for a series of published inventories, by countries, of all the imported medieval and post medieval pottery recovered from excavations and field walking in Scotland, was advanced on the final day of the Medieval Pottery Research Group’s conference held in Edinburgh in May 2001. Taking on the roll of creating a gazetteer and catalogue of French pottery in Scotland, it was the authors aim to build on the pioneering work of John Hurst and other medieval ceramicists and in the process make a contribution to the ongoing research on identifiable medieval and post-medieval ceramics traded around the North and Irish Sea

No full textMature microRNAs (miRNAs) are processed from primary transcripts (pri-miRNAs), and their expression is controlled at transcriptional and post-transcriptional levels. However, how regulation at multiple levels achieves precise control remains elusive. Using published and new datasets, we profile a time course of mature and pri-miRNAs in Drosophila embryos and reveal the dynamics of miRNA production and degradation as well as dynamic changes in pri-miRNA isoform selection. We found that 5’ nucleotides influence stability of mature miRNAs. Furthermore, distinct half-lives of miRNAs from the mir-309 cluster shape their temporal expression patterns, and the importance of rapid degradation of the miRNAs in gene regulation is detected as distinct evolutionary signatures at the target sites in the transcriptome. Finally, we show that rapid degradation of miR-3/–309 may be important for regulation of the planar cell polarity pathway component Vang. Altogether, the results suggest that complex mechanisms regulate miRNA expression to support normal development.NRF (Natl Research Foundation, S’pore)MOE (Min. of Education, S’pore)Published versio
