John Antill's Symphony on a City (1959) and its place within the Australian symphonic repertory of the 1950s

John Antill is often perceived as being a 'one work' composer owing to the prominence and success of Corroboree. The remainder of his large output is largely neglected. Symphony on a City, commissioned by and dedicated to the City of Newcastle in 1959, is described by James Murdoch (1972) as a major work that has been performed only once. Roger Covell (1967) wrote that the symphony 'should be heard again, because in it Antill does find, even if only momentarily, other ways of representing energy at high voltage'. Perhaps this is the work that could provide a counter-balance to the predominance of Corroboree in Antill's work. This paper describes the formal and stylistic aspects of the symphony, relates it to Corroboree and Antill's overall orchestral output and then places the work against the backdrop of Australian symphonies of the 1950s and the wider international context. The symphony emerges as one of the more important Australian symphonic works of its period and worthy of preservation and revival

Setback in Secularization: Church and State Relations under the Duterte Administration

As he moves closer to half of his term as president of the Philippines, Rodrigo Roa Duterte has continually been in friction with the Catholic Church, specifically with certain members of its hierarchy. Mainly identifiable as the dividing line between Duterte’s administration and the Church is the issue on human rights particularly the extrajudicial killings (EJK) of suspected users and pushers of illegal drugs. This paper argues that Duterte’s attitude and positioning towards the Catholic Church neither strengthen nor advance the Philippine state towards a greater degree of secularization. On the contrary, the Church has become more politically and publicly involved. Consequently, it has remained a key actor or interest group providing an alternative moral discourse to that of the government

The hall effect — an important diagnostic tool

AbstractThe quantitative measurement of carrier concentrations and mobilities is of vital importance in the assessment of semiconductor materials. One of the best-established methods of doing this relies on the Hall effect, which was discovered as long ago as 1880 by E.H. Hall in his investigations of metals. This article introduces the basic theory of the Hall effect at a fairly elementary level, with a minimum of mathematics, and discusses how it can be used to determine semiconductor parameters. It does not attempt to cover the more advanced developments of the subject, such as the quantum Hall effect

The effects of temperature and time of first feeding on egg and fry development in Atlantic salmon, salmo salar L.

The first part of this study investigated the effects of varying temperature regimes within the range of 8-22°C on the development and survival of Atlantic salmon (Salmo salar L.) eggs and alevins. The temperature tolerance of eggs was lower than that of alevins: egg mortality increased above 11°C and no eggs survived to eyeing or to hatching at 16 and 14°C, respectively; alevin mortality increased above 16°C and no alevins survived at 22°C. Optimal survivals of eggs and alevins occurred at 8-11°C and 10-14°C, respectively. Subsequent survival at later stages of development was largely determined by survival at earlier stages. Developmental abnormalities among eggs (pin-eyed eggs) and alevins (abnormal hatching and yolk-sac oedema) appeared to be temperature-dependent. Development time in days from fertilisation to eyeing, hatching and maximum alevin wet weight (MAWW) varied inversely with temperature. The sum of degree-days from fertilisation to eyeing and to MAWW was similar at all temperatures, but declined with increasing temperature from eyeing to hatching. The hatching period was similar for all temperatures except 8°C where it was significantly longer. Although alevin size at hatching was not temperature-dependent within the range of 8-12°C, alevin size at MAWW decreased progressively with increasing temperature (10-20°C) during the alevin stage. Fry size at first feeding did not affect their subsequent growth rate or survival. Advanced fry which were fed earliest grew at similar rates to those produced at lower temperatures and attained the greatest weight. Biomass gain was more dependent upon survival than upon mean fish weight. The second part of this study investigated the effects of timing of first feeding on fry growth and survival. Alevins fed prior to final yolk resorption were larger and had lower mortalities than those fed after MAWW. Although the "window" of first feeding opportunity lasted several weeks, delaying feeding beyond MAWW reduced absolute growth. A 5-week delay led to mortalities approaching 60%. However, first feeding can be delayed beyond MAWW for 1-2 weeks at 10°C without adversely affecting subsequent survival or growth rate

Applications of quartz crystal microbalance technology in petroleum engineering, demonstrated by studies of wax, asphaltenes, hydrates, ice, diesel additives and anti-deposition coatings

This thesis describes the development and uses of equipment and methods based upon the use of quartz crystal microbalance (QCM) technology for measurements involving major Flow Assurance issues, namely wax, asphaltene and hydrate in addition to ice formation in processing facilities, deposition of diesel performance additives in injectors and evaluation of anti-depositional paint coatings. For wax, the use of QCM for accurate measurements of the solubility of wax in synthetic binary and quaternary mixtures of n-alkanes is demonstrated and validated against literature data and model predictions. The use of the QCM for measurements of wax appearance temperature (WAT) and wax disappearance temperature (WDT) for stabilised and live reservoir fluids is presented. The development of QCM based equipment for investigating the effect of temperature gradient on wax deposition tendency at ambient and high pressure is described. The development and validation of the application of QCM technology for comparing and optimising dose rates for wax inhibitors at atmospheric and high pressure is presented. Wax case studies employing the developed equipment and methods are included. In the case of asphaltenes the potential use of QCM based equipment for measuring asphaltene onset in standard solvent titration measurements is shown. In addition by comparing step-wise and continuous injection results, potential errors in asphaltene stability measurements are highlighted. QCM tests with live fluids show that asphaltene onset can be readily detected in reservoir fluids at high pressure/high temperature conditions. In addition reversibility of asphaltene deposition can be demonstrated. Measurement of the effectiveness of asphaltene inhibitor treatments in terms of reducing solids deposition is demonstrated at operating conditions. Asphaltene case studies using the developed equipment and methods are presented. With hydrates, the development of QCM based equipment for measurement of hydrate dissociation points is presented. The use of QCM to identify solids forming in a dew pointing and mercaptan removal unit is described. The development of high pressure/high temperature equipment to detect deposition of diesel performance additives in injectors is presented. Finally the evaluation of anti-deposition coatings for scale and wax is described

Local Discourse, Identity and the Search for a Filipino Philosophy: A Re-exploration through the Lens of Reynaldo Ileto

Working within the framework of Reynaldo Ileto’s postcolonial discourse, this paper re-explores the Filipino philosophy question and its contem- porary relevance. Re-exploration in this context means re-reading and arguing for sustained discussions on Filipino philosophy. Divided into three parts, the paper presents the history and development of the Filipino philosophy debate and proceeds to an analysis and reflection on Ileto’s writing from Pasyon and Revolution to his more recent work. The third and final part proposes a rethinking of what has been identi- fied as Filipino philosophy in the light of Ileto’s ideas. At the core of this endeavor is the contention that a culture-grounded philosophy is indispensable in nationhood and state-formation. Thus, whether it shall be called “philosophies in the Philippines” or “Filipino philosophy,” or whatever possible nomenclature for such an endeavor, the most es- sential thing is that Filipinos consciously identify and shape their own discourse as a people. Finally, this paper argues for the relevance of continually discussing the question concerning Filipino philosophy

Electrical transport across Au/Nb:SrTiO3 Schottky interface with different Nb doping

We have investigated electron transport in Nb doped SrTiO$_3$ single crystals for two doping densities. We find that the resistivity and mobility are temperature dependent in both whereas the carrier concentration is almost temperature invariant. We rationalize this using the hydrogenic theory for shallow donors. Further, we probe electrical transport across Schottky interfaces of Au on TiO$_2$ terminated n-type SrTiO$_3$. Quantitative analysis of macroscopic I-V measurements reveal thermionic emission dominated transport for the low doped substrate whereas it deviates from such behavior for the high doped substrate. This work is relevant for designing devices to study electronic transport using oxide-semiconductors.Comment: 10 Pages, 3 Figure

High magnetoresistance at room temperature in p-i-n graphene nanoribbons due to band-to-band tunneling effects

A large magnetoresistance effect is obtained at room-temperature by using p-i-n armchair-graphene-nanoribbon (GNR) heterostructures. The key advantage is the virtual elimination of thermal currents due to the presence of band gaps in the contacts. The current at B=0T is greatly decreased while the current at B>0T is relatively large due to the band-to-band tunneling effects, resulting in a high magnetoresistance ratio, even at room-temperature. Moreover, we explore the effects of edge-roughness, length, and width of GNR channels on device performance. An increase in edge-roughness and channel length enhances the magnetoresistance ratio while increased channel width can reduce the operating bias.Comment: http://dx.doi.org/10.1063/1.362445
