The Temple

Borobudur temple has been famously known as one of the Indonesian heritage masterpiece. Various aspects of it had been studied thoroughly since the beginning of 20th century A.D. Those studies tended to be monumental centric, giving less attention to the cultural context of the temple and its surroundings. Settlement in the nearby places is one of the topics which not have been studied much yet; leaving a big question about how the settlement supported continuity of many activities in the temple, or even the other way around; how the temple affected the settlement. There is only a few data about old settlement found in situ in Borobudur site, only abundance of pottery sherds. The analysis applied on to the potteries find during the 2012 excavation had given some information about the old settlement in Borobodur site. The old settlement predicted as resided in the south west area, in the back side of the monument.

Gallium Alloy

Two metal foils, one pure plutonium and the other being a solid solution of 6.5 a/o gallium In plutonium, were examined, in-situ, by X-ray diffraction techniques while under pressure. The purpose was to determine the compression and compressibility of these materials as a function of pressure and to identify the products of any transformation that may occur due to the action of applied pressures.

Abstract Carillons are a diverse and global form of musical and civic heritage: musical instruments comprised of a series of 23 or more bells, typically hung in a tower-like structure, tuned chromatically and played from a touch-sensitive manual and pedal console using an elaborate mechanical action. Carillon bells have a distinct series of musical overtones which need to be accurately tuned to one another and with other bells they sound alongside. Although these overtones have been previously studied ex situ, this study assesses the acoustic characteristics of two early-20th century carillons in Toronto, Canada as a combination of structure, bells, and mechanical action. Thus, the instrument and its context are considered holistically, more accurately reflecting the musical sensitivity of a carillonist. Spectral and Fourier analysis of audio samples of each bell at different musical dynamic levels enabled the analysis of the acoustic qualities of the bells and the mechanical action of the instruments. The tuning of bells in the instruments varied; most importantly, there was a significant difference between the audial intensity of the bell tones produced by the instruments, demonstrating the importance of the mechanical action as part of the ‘carillon system’. This was represented with a resistive power-law model, that represents the sensitivity of intensity to carillonist musical dynamic level. A discussion of the implications for artistic and heritage practice follows. Understanding the in situ physical acoustics of the carillon as a holistic instrument in its context informs performers, arrangers, and composers of how they can best embrace the instrument’s unique qualities to improve artistic pursuits and support the appreciation of carillons as heritage instruments and function as civic voices.

New Findings

Abstract This paper presents new findings from our study in situ of a small Christian church, known as Göreme 31, which is situated above the Kılıçlar church in Göreme (Cappadocia, Turkey). It was discovered and briefly described at the beginning of the 20th century, but after that almost no additional information was published. We were able to study Göreme 31 in situ in 2014–2015. In this article, we present new findings and updated information on this church: data on three previously unpublished murals in the naos, corrections to the readings of the frescoes of St. Auxentius (previously identified as St. Vincent), St. Sisinius (previously identified as St. Irene), and St. George with St. Theodore, and discussion of the enigmatic tiny grave in the funeral chamber.

Clement Meadmore was a major 20th-century sculptor with many works in situ across North America, Australia, and Japan. They were often commissioned as design features within substantial architectural installations and urban design projects in the International Style. Their heroic and rhetorical positioning on the forecourts of large corporate towers, on university campuses, and other public institutions could almost be classified as a cliché of mid- to late-20th-century visual experience, except that his works captured attention on their own merits.

Physical oceanography has been practiced in Atlantic Canada since the beginnings of the science in the second half of the 19th century. Pursued largely as an applied science, its efforts have been directed toward providing information to mariners and other marine users. Early efforts focused on tidal observations to promote safe navigation. This was expanded in the early 20th century to regional studies in support of fisheries. In the second half of the 20th century, physical oceanography in Atlantic Canada grew to support the offshore development of oil and gas, provide more comprehensive environmental assessments of marine projects and processes, improve Search and Rescue responses and to better understand and predict climate change and variability.Oceanographers now have the capabilities to observe the ocean in near real-time using satellites as well as autonomous in situ instruments. The continued growth in computer power and other information technologies has permitted the development of operational ocean models that can provide real-time information and projections on oceanic conditions to a broad section of the marine community.L’océanographie physique est pratiquée au Canada atlantique depuis les débuts de cette science au cours de la deuxième moitié du XIXe siècle. Les travaux dans ce domaine, menés dans une grande mesure sous forme appliquée, sont axés principalement sur la fourniture de renseignements aux gens de mer et aux autres utilisateurs du milieu marin. Les premiers travaux ont porté sur les observations des marées afin d’assurer la sécurité en mer. Au début du XXe siècle, des études régionales ont été lancées pour appuyer les activités de pêche. Au cours de la deuxième moitié du XXe siècle, l’océanographie physique au Canada atlantique a continué de croître pour maintenant appuyer les projets de mise en valeur du pétrole et du gaz en milieu extracôtier, fournir des évaluations environnementales plus détaillées des projets en milieu marin et des processus liés à ce milieu, améliorer l’intervention dans le cadre d’opérations de recherche et de sauvetage, approfondir les connaissances sur le changement climatique et la variabilité et améliorer les prévisions relatives à ceux-ci. Les océanographes ont maintenant la capacité d’observer l’océan presque en temps réel grâce à des satellites et à des instruments autonomes in situ. L’améliorationcontinue de la puissance des ordinateurs et d’autres technologies de l’information a rendu possible l’élaboration de modèles océaniques opérationnels qui peuvent fournir des données et prévisions en temps réel sur les conditions océaniques à une part importante de la communauté maritime.
