title: In situ synchrotron high-energy X-ray diffraction analysis on phase transformations in Ti–Al alloys processed by equal-channel angular pressing

authors: Liss, Klaus-Dieter

subjects: Ti

abstract: Mixtures of 47-Al and 53-Ti powders (atomic %) have been consolidated using back pressure equal-channel angular pressing starting with both raw and ball-milled powders. In situ synchrotron high-energy X-ray diffraction studies are presented with continuous Rietveld analysis obtained upon a heating ramp from 300  K to 1075  K performed after the consolidation process. Initial phase distributions contain all intermetallic compounds of this system except Al, with distribution maxima in the outer regions of the concentrations (α-Ti, TiAl3). Upon annealing, the phase evolution and lattice parameter changes owing to chemical segregation, which is in favour for the more equilibrated phases such as γ-TiAl, α2-Ti3Al and TiAl2, were followed unprecedentedly in detail. An initial δ-TiH2 content with a phase transition at about 625  K upon heating created an intermediate β-Ti phase which played an important role in the reaction chain and gradually transformed into the final products.

title: Rural tourism development in Lithuania (2003–2010) — A quantitative analysis

authors: Baležentis, Tomas

abstract: The objectives of the Rural Development Programme for Lithuania for the period 2007 to 2013 are to: (a) preserve natural and cultural heritage objects, (b) support complementary activity in the rural areas, and (c) generate rural tourism as an economic sector. The aim of this study is to identify current trends specific to the Lithuanian rural tourism sector and propose potential means of development. This study focuses on an inter-county assessment of rural tourism flows within Lithuania by the means of an index decomposition analysis. Consequently, an analysis was undertaken covering factors including the number of the rural tourism farmsteads, spatial distribution of those farmsteads, and capacity, an amended Defert Index, and duration of stay effects. The analysis suggests that the Lithuanian rural tourism sector was negatively affected by the 2008 recession. Indeed, the impacts exhibited relatively high elasticity of demand for rural tourism. Hence, there is a need for the further development of appropriate marketing and information dissemination strategies aimed at both middle and lower income consumers.

title: Portfolio of compositions

authors: Hoadley, Benjamin Russell

subjects: New Zealand composition

abstract: The music in this portfolio of original compositions is steeped in the Western tradition of tonal music. The pieces were written while also pursuing a professional career as a bassoonist touring internationally and performing a wide variety of western art music, from Renaissance to contemporary. I have responded to these influences consciously and unconsciously in my music. The overarching focus of this composition portfolio is to provide an answer to the question — to what extent do musical influences impact on the compositions of an international touring performer?

Underpinning the portfolio is the fact that the pieces were all written in New Zealand during periods of intense reflection and study. While I am constantly collecting ideas and inspiration for my music while travelling, I consolidate and realise these ideas only when I am home.

I identify with being a New Zealand composer, with cosmopolitan influences on my music reflecting the global influences on New Zealand’s culture and art. Working closely with composers performing their music has also informed my composition. I mention Gillian Whitehead in particular, whose music I have performed widely.

The two outer pieces in the portfolio, Huia and Manaia 4 are the most directly associated with New Zealand in their subject matter. Other pieces have foreign themes, from my nocturnal impressions of New York in Night Music to the Ancient Greece of Ostrakon to the West African poetry of Four Songs.

All of the pieces were written for professional musicians to perform, including the Auckland Philharmonia Orchestra and the Sydney Omega Ensemble. Having these outstanding performers in mind while writing, and interacting with these musicians during the composition process, has informed my writing.
