The Cost and Value of Heritage in Singapore The Belitung Shipwreck and Bukit Brown. The forum panel included Dr Michael Flecker, Managing Director of Maritime Explorations, Dr Hui Yew Foong, Fellow at the Institute of Southeast Asian Studies ISEAS, Mr Kwa Chong Guan, Member of the National Heritage Board and the Chairman of the National Archives Board, and Assistant Professor Jack Tsen Ta Lee, faculty member at the School of Law, Singapore Management University. The panel was chaired by Dr Kevin Tan, Immediate Past President of the Singapore Heritage Society. The forum was organised by the Singapore Heritage Society and the School of Law, Singapore Management University, and was held in the Mochtar Riady Auditorium in SMUs Administration Building along Victoria Street. One purpose of the forum was to raise public awareness of recent heritage issues concerning Singapore, and another was to try to deepen understanding of such issues beyond conventional perceptions. Articles in journals or periodical publications Mona Abaza, Intellectuals, Power and Islam in Malaysia S. N. alAttas or the Beacon on the Crest of a Hill, in. The forum was opened by Dr Chua Ai Lin, Vice President of the Singapore Heritage Society. She shared some thoughts on the theme of the forum, and encouraged more conversations about aspects of our past that are important to us at all levels, from the family dinner table to national level discussions. These private and public conversations form the starting point from which we can all play a role in determining the direction Singapore wants to adopt in identifying and conserving its heritage. The forum was then divided into two portions 1 presentations by the panelists to introduce their area of expertise to the audience as well as to deliberate on the theme of the forum, and 2 a dialogue between the panel and the audience. Michael Flecker spoke first, sharing his experiences and insights gleaned from more than two decades of archaeological excavations of ancient shipwrecks, in particular the Belitung Shipwreck. The shipwreck is a ninth century Arabian dhow found near Belitung, an island off the east coast of Sumatra.

It was carrying a near intact cargo of Tang Dynasty artefacts, all of which was bought by the Singapore government in 2. Commenting on the controversy which engulfed the Smithsonian Institution last year, Flecker thought it was a pity the artefacts from the Belitung Shipwreck were not exhibited as they held significant educational value. He also noted that the Belitung artefacts are a valuable heritage resource for Singapore, as they shed light into an earlier part of Singapores history not fully researched just yet. Hui Yew Foong followed with a presentation on a more local and perhaps a slightly hotter issue, that is the debate over the present and future situation of the Bukit Brown area. As the primary researcher in the on going documentation of graves affected by the proposed eight lane expressway through the historic cemeteries and a veteran too of other grave documentation exercises, Hui introduced, with quiet authority, the audience to the Bukit Brown area and the cemeteries situated within, and the intrinsic heritage value they hold for Singapore. While acknowledging the merits of the on going documentation process, he cautioned that documentation is only a mere representation of the heritage value, and cannot act as a substitute for what stands to be lost. Jack Tsen Ta Lee was next and his presentation on the legalities posed by the Belitung Shipwreck and Bukit Brown were thought provoking. Regarding the former, Lee noted as Flecker did before that the excavation and recovery of the Tang era artefacts were in fact legal, i. Indonesian Government. The debate and controversy were over ethical issues, i. Regarding Bukit Brown, Lee deliberated over the possibility of bringing a judicial review to the Government, in other words to sue the Government to prevent the construction of the eight lane expressway. Although Lee concluded mostly in the negative as it would be difficult in this case to prove the Government has acted unreasonably, his presentation provided much insight into workings of the law and the responsibilities of the High Court and Government. It is not the role of the High Court to ensure Government makes the right decision, but rather it is there to ensure Government has acted lawfully. Kwa Chong Guan wrapped up the first part of the forum with a more scholarly but no less significant and insightful take on both the Belitung Shipwreck and Bukit Brown issues. An experienced operator within the fields of heritage and historical scholarship for over three decades, Kwa suggested that there was little doubt over the value of both issues to understanding and broadening Singapores heritage landscape. The question perhaps is how the value would be interpreted and whether it would be accepted by most if not all.

International Journal of Engineering Research and Applications IJERA is an open access online peer reviewed international journal that publishes research. The Belitung Shipwreck for instance was an Arabian dhow in Indonesian waters. Still, its cargo provides a window into a world before Singapore was a colony or a nation state, allowing for a different yet relevant interpretation of Singapores past. Similarly, the current debates over the status of the Bukit Brown area and the cemeteries within arguably bring to light the value of cultural and natural heritage to Singaporeans, and perhaps also how they wish for Singapore to be remembered now and in the future. The public Q A discussion which followed was efficiently moderated by Kevin Tan, allowing for a broad range of views and questions to be aired. Given its recentness, it was no surprise that Bukit Brown dominated the comments and opinions posed by the audience. Some of the more interesting comments included possible issues that could form the basis of a judicial review of the Governments decision to build expressway a query which also brought Tan, a leading constitutional lawyer and scholar, into the mix and a comment about how Singaporeans seemed to be stung into action only when historic places such as Bukit Brown or the former KTM railway land were being threatened, which led to some discussion as to how Singaporeans can be more proactive about identifying, protecting and promoting their heritage. All in all, it was an educational and enjoyable afternoon. The insightful presentations, the ensuing panel discussion and the incisive and passionate comments and questions from the audience left no one in doubt that heritage issues in Singapore will be well tended to in the near and distant future.

Rasaratna Samuccaya 8. Main isotopes of zinc. Wikidata. Zinc is a chemical element with symbol Zn and atomic number 3. It is the first element in group 1. In some respects zinc is chemically similar to magnesium both elements exhibit only one normal oxidation state 2, and the Zn. Mg. 2ions are of similar size. Zinc is the 2. 4th most abundant element in Earths crust and has five stable isotopes. The most common zinc ore is sphalerite zinc blende, a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity electrowinning. Brass, an alloy of copper and zinc in various proportions, was used as early as the third millennium BC in the Aegean, Iraq, the United Arab Emirates, Kalmykia, Turkmenistan and Georgia, and the second millennium BC in West India, Uzbekistan, Iran, Syria, Iraq, and Israel3 Judea4. Zinc metal was not produced on a large scale until the 1. India, though it was known to the ancient Romans and Greeks. The mines of Rajasthan have given definite evidence of zinc production going back to the 6th century BC. To date, the oldest evidence of pure zinc comes from Zawar, in Rajasthan, as early as the 9th century AD when a distillation process was employed to make pure zinc. Alchemists burned zinc in air to form what they called philosophers wool or white snow. The element was probably named by the alchemist Paracelsus after the German word Zinke prong, tooth. German chemist Andreas Sigismund Marggraf is credited with discovering pure metallic zinc in 1. Work by Luigi Galvani and Alessandro Volta uncovered the electrochemical properties of zinc by 1. Corrosion resistant zinc plating of iron hot dip galvanizing is the major application for zinc. Other applications are in electrical batteries, small non structural castings, and alloys such as brass. A variety of zinc compounds are commonly used, such as zinc carbonate and zinc gluconate as dietary supplements, zinc chloride in deodorants, zinc pyrithione anti dandruff shampoos, zinc sulfide in luminescent paints, and zinc methyl or zinc diethyl in the organic laboratory. Zinc is an essential mineral, including to prenatal and postnatal development. Zinc deficiency affects about two billion people in the developing world and is associated with many diseases. In children, deficiency causes growth retardation, delayed sexual maturation, infection susceptibility, and diarrhea. Enzymes with a zinc atom in the reactive center are widespread in biochemistry, such as alcohol dehydrogenase in humans. Consumption of excess zinc can cause ataxia, lethargy and copper deficiency. CharacteristicseditPhysical propertieseditZinc is a bluish white, lustrous, diamagnetic metal,1. It is somewhat less dense than iron and has a hexagonal crystal structure, with a distorted form of hexagonal close packing, in which each atom has six nearest neighbors at 2. The metal is hard and brittle at most temperatures but becomes malleable between 1. C. 1. 21. 3 Above 2. C, the metal becomes brittle again and can be pulverized by beating. Zinc is a fair conductor of electricity. For a metal, zinc has relatively low melting 4. C and boiling points 9. C. 1. 6 The melting point is the lowest of all the d block metals aside from mercury and cadmium for this, among other reasons, zinc, cadmium, and mercury are often not considered to be transition metals like the rest of the d block metals are. Many alloys contain zinc, including brass. Other metals long known to form binary alloys with zinc are aluminium, antimony, bismuth, gold, iron, lead, mercury, silver, tin, magnesium, cobalt, nickel, tellurium, and sodium. Although neither zinc nor zirconium are ferromagnetic, their alloy Zr. Zn. 2 exhibits ferromagnetism below 3. K. 1. 2A bar of zinc generates a characteristic sound when bent, similar to tin cry. OccurrenceeditZinc makes up about 7. Earths crust, making it the 2. Soil contains zinc in 57. Seawater has only 3. The element is normally found in association with other base metals such as copper and lead in ores. Zinc is a chalcophile, meaning the element has a low affinity for oxides and prefers to bond with sulfides. Chalcophiles formed as the crust solidified under the reducing conditions of the early Earths atmosphere. Sphalerite, which is a form of zinc sulfide, is the most heavily mined zinc containing ore because its concentrate contains 6. Other source minerals for zinc include smithsonite zinc carbonate, hemimorphite zinc silicate, wurtzite another zinc sulfide, and sometimes hydrozincite basic zinc carbonate. With the exception of wurtzite, all these other minerals were formed by weathering of the primordial zinc sulfides. Identified world zinc resources total about 1. Large deposits are in Australia, Canada and the United States, with the largest reserves in Iran. The most recent estimate of reserve base for zinc meets specified minimum physical criteria related to current mining and production practices was made in 2. Mt. 2. 6 Zinc reserves, on the other hand, are geologically identified ore bodies whose suitability for recovery is economically based location, grade, quality, and quantity at the time of determination. Since exploration and mine development is an ongoing process, the amount of zinc reserves is not a fixed number and sustainability of zinc ore supplies cannot be judged by simply extrapolating the combined mine life of todays zinc mines. This concept is well supported by data from the United States Geological Survey USGS, which illustrates that although refined zinc production increased 8. About 3. 46 million tonnes have been extracted throughout history to 2. IsotopeseditFive isotopes of zinc occur in nature. Zn is the most abundant isotope 4. That isotope has such a long half life, at 7. Similarly, 7. 0Zn 0. The other isotopes found in nature are 6. Zn 2. 8, 6. 7Zn 4 and 6. Zn 1. 9. Several dozen radioisotopes have been characterized.
