EMILY HOWARD (b. 1979)Wild Clematis in Winter (2008)

This chapter focuses on Emily Howard’s Wild Clematis in Winter (2008). In this piece, perfect control and precision of intonation are required of the singer. Even from the start, the mezzo is left exposed on long-held pitches, often in the potentially vulnerable register-break area. The piano sets the atmosphere with delicate, oscillating semitones, merged by the pedal, grounded by a constantly repeating G natural in the bass. This pattern is to continue through much of the song. Meanwhile, the singer’s exquisitely poised, hypnotic lines gradually gather intensity over a wide spectrum of dynamics. Phrases become more passionate, with single repeated notes conveying a wealth of meaning in their carefully graded dynamics. Throughout, the accompaniment stays within a restricted pitch area, and there are plenty of cues to keep the singer anchored.

Development and Application of Dose Assessment Methodology During IS-LOCA in BWR Plant

A dose assessment methodology was developed for IS-LOCA (Interface System – Loss of Coolant Accident) event, which is one of the design basis accidents in BWR plants, and a dose assessment at site boundary was implemented for the accident scenario by applying the evaluation method. The main objective of the assessment is to review a conventional conservative dose assessment model in the accident scenario. The conventional conservative model is a method due to considering all fission products (FP) in liquid migrate to airborne (i.e. 100%) when reactor water is discharged from piping break area, while the developed new methodology is a method to evaluate transition behavior of fission products precisely by using flash fraction (FF) from liquid to airborne and consider it. As the result of dose assessment, it was confirmed that the calculated dose during IS-LOCA event was about one-fifteith reduced by adopting the new model from the conventional model. The content of this paper includes: • Background and purpose that led to the dose assessment methodology development during IS-LOCA. • An evaluation method by using discharged amount of reactor water at piping break area and flash fraction (FF) from liquid to airborne based on Regulatory guide 1.183 published by U.S. NRC. • Another evaluation method that takes into account the fluctuation due to depressurization of reactor pressure per time step from the start of accident until completion of isolation at piping break area in addition to the above method. • Comparison between dose results at site boundary based on these methods and conventional conservative model. This results will give a precise information for public and it will be useful for making emergency evacuation plan.

ROGER SESSIONS (1896–1985)On the Beach at Fontana (1929)

This chapter discusses a brief but intricate song by Roger Sessions. Sessions is recognized as one of the most cosmopolitan and influential of senior American composers, and this is the sole example of his writing for voice and piano. The piece seems especially suited to a tenor, since there is some concentration around the register break area near the top of the stave. It is certainly not the easiest of songs to sing, but its originality and powerful atmosphere are memorable, and are sure to repay the effort necessary to make it flow smoothly. Furthermore, subtlety of rhythm is the work’s hallmark. Interplay between simple and compound note groupings within a basic 6/8 metre creates a nervous energy and a febrile ebb and flow that fits the text perfectly.

REVITALIZING AREA STUDIES: BUILDING THEMATIC RESONANCE THROUGH RECONCILIATION

Area Studies has garnered a lot of criticisms over the past several decades. This, of course, is to be expected as the initial foundation of the study itself is polemical, and very much colonial. Many have seen area studies as antiquated, unable to rise to the challenges of globalization. Indeed, as a project that relies upon “areas” conventionally demarcated, globalization poses as the threat/potential double-bind that can make or break area studies. Stepping up to the challenge, area studies have been in dialogue with other disciplines such as diaspora studies, postcolonial studies and cultural studies that have become prominent critics of area studies. These flirtations have been fruitful for more alternatives and possibilities come to fore. In the same vein, the nature of this writing is to build a dialogue between area-based knowledge and the travelling ideas spurred by globalization, and in doing so, hoping that such dialogue will produce thematic issue that connects localities, history, and knowledge production. This paper proposes the discourse of reconciliation as a thematic issue to reconnect and re-integrate different “areas” in the larger project of Area Studies.

CFD Modelling of Loss of Vacuum Accident (LOVA) for CFETR

Chinese Fusion Engineering Testing Reactor (CFETR) is a tokamak-type machine and next device in the roadmap for the realization of fusion energy in China, which aims to bridge the gaps between the International Thermonuclear Experimental Reactor (ITER) and the demonstration reactor (DEMO) [1]. The accident sequence starting from loss of vacuum accident (LOVA) is an important issue concerning the performance of CFETR. During LOVA, air will leak into the vacuum vessel (VV) causing fast pressurization of VV. At the same time, the high speed airflow jet will result in migration and re-suspension of the large quantity of tungsten dust produced and deposited in the lower part of plasma chamber, causing possibilities of radioactive dust leakage into the workshop and environment. In order to conduct a comprehensive analysis of the accident sequence, firstly, the airflow characteristics of LOVA should be studied. In this article, a postulated rupture of different section area is assumed due to a failed component at the equatorial port level. The computational fluid dynamic (CFD) modelling of LOVA was conducted by ANSYS CFX. The results show that the break area has significant influences on the characteristics of the airflow. Two swirling airflows are formed in the upper and lower part of the torus. The airflow characteristics are quite different when the LOVA happens during maintenance or during normal operation. A reverse flow occurs when the LOVA happens during normal operation. Yet can not be observed when LOVA occurs during maintenance. The results are the basis to the further safety study of CFETR such as the re-suspension, migration and explosion of dust.

Preliminary Analysis of Influence of Uncertainty Parameters for CAP1400 LBLOCA Accident

The best-estimated methodology is applied for CAP1400 LBLOCA. Based on the sampling and calculation results, the influence of uncertainty parameters including plant initial conditions parameters, core power distribution parameters, global system thermal-hydraulic parameters and local hot rod parameters are evaluated. The major uncertainty parameters are figured out. Moreover, all uncertainty parameters considered in CAP1400 LBLOCA are ranked by their influences. The analysis results show that the break area, relative power of middle third of core, the accumulator initial pressure give the most contribution to PCT of CAP1400 LBLOCA. The uncertainty parameters could be optimized according this paper in the future.

STRATIGRAFI SEISMIK LAUT DANGKAL PERAIRAN CELUKANBWANG, BALI UTARA

Suvai seismik laut sepanjang pantai dan lepas pantai Celukanbawang Bali Utara dimaksudkan untuk mendapatkan data rekaman seismik guna menerangkan kondisi geologi daerah telitian. Berdasarkan pendekatan stratigrafi seismik, rekaman data seismik menunjukkan bahwa di daerah telitian terdapat 2 (dua) runtunan seismik, yaitu runtunan A dan B. Runtunan A diduga merupakan batuan volkanik sedangkan runtunan B diduga merupakan batuan sedimen yang diendapkan dalam lingkungan energi cukup kuat. Pada daerah slope break banyak dijumpai diapir, dan struktur geologi yang berkembang di daerah telitian adalah sesar normal. The marine seismic survey along the coast and offshore of Celukanbawang, North Bali, was directed to obtained seismic records to explain the geological condition of the study area. On the basis of seismic stratigraphy approach, the seismic records indicate that in the study area presence 2 (two) seismic sequences, those are sequence A and B. Sequence A is suggested as a volcanic rocks while sequence B is suggested as sedimentary rocks deposited within strong energy environment. At the slope break area the diapers were found, and the geological structures develope in the study area are normal faults.

Sizing of the Vacuum Vessel Pressure Suppression System of a Fusion Reactor Based on a Water-Cooled Blanket, for the Purpose of the Preconceptual Design

A methodology to preliminarily evaluate the size of the suppression tank and the relief pipes for a Vacuum Vessel Pressure Suppression System, to be adopted in a fusion reactor based on a water cooled blanket, is presented. The volume of the ST depends on the total energy of the water cooling system and it can be sized based on a required final pressure at equilibrium, by a simple energy balance. The pressure peak in the VV depends mainly on break area and the flow area of the relief pipes and some suggestions about the method for a preliminarily evaluation of their size are discussed. The computer code CONSEN has been used to perform a parametric study and to verify the methodology.
