Robert Brill
Dr Robert Brill is in the field of archaeological science, best known for his work on the chemical analysis of ancient glass. Born in the United States of America in 1929, Brill attended West Side High School in Newark, New Jersey, before going on to study for his B.S. degree at Upsala College (Brill 1993a, Brill 2006, Getty Conservation Institute 2009). Having completed his Ph.D. in physical chemistry at Rutgers University in 1954, Brill returned to Upsala College to teach chemistry. In 1960, he joined the staff of the Corning Museum of Glass as their second research scientist (Corning Museum of Glass, 2009) Throughout his career at Corning, where a four-year directorship punctuated his time as a research scientist, Brill was a forerunner in the scientific investigation of glass, glazes and colorants, developing and challenging the usefulness of emerging techniques. His pioneering work with the application of lead and oxygen isotope analysis in archaeology led him occasionally to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass
Glass is a non-Crystallinity, crystalline, often transparency and translucency, transparent, amorphous solid that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the Melting, molten form; some glasses such as volcanic glass are naturally occurring. The most familiar, and historically the oldest, types of manufactured glass are "silicate glasses" based on the chemical compound silicon dioxide, silica (silicon dioxide, or quartz), the primary constituent of sand. Soda–lime glass, containing around 70% silica, accounts for around 90% of manufactured glass. The term ''glass'', in popular usage, is often used to refer only to this type of material, although silica-free glasses often have desirable properties for applications in modern communications technology. Some objects, such as drinking glasses and glasses, eyeglasses, are so commonly made of silicate- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Al-Jalama, Haifa
Al-Jalama ( ar, الجلمة) was a Palestinian village about 14 kilometres south-east of Haifa. It was depopulated in 1948. History The village was situated just above Khirbat Asafna. Excavations between 1964 and 1971 showed that the site had been occupied intermittently from the first to the fourth century CE. In the British Mandate period in Palestine, the village was classified as a hamlet in the ''Palestine Index Gazetteer.''Khalidi, 1992, p. 167 In the 1931 census of Palestine, Al-Jalama was counted under Isfiya. In 1948 al-Jalama was depopulated and the area was subsequently incorporated into the State of Israel Israel (; he, יִשְׂרָאֵל, ; ar, إِسْرَائِيل, ), officially the State of Israel ( he, מְדִינַת יִשְׂרָאֵל, label=none, translit=Medīnat Yīsrāʾēl; ), is a country in Western Asia. It is situated ... after the war. The Kishon prison, also known as the Al Jalame detention centre, was later established on the ...

Atomic Absorption Spectroscopy
Atomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) is a spectroanalytical procedure for the quantitative determination of chemical elemlight) by free atoms in the gaseous state. Atomic absorption spectroscopy is based on absorption of light by free metallic ions. In analytical chemistry the technique is used for determining the concentration of a particular element (the analyte) in a sample to be analyzed. AAS can be used to determine over 70 different elements in solution, or directly in solid samples via electrothermal vaporization, and is used in pharmacology, biophysics, archaeology and toxicology research. Atomic emission spectroscopy was first used as an analytical technique, and the underlying principles were established in the second half of the 19th century by Robert Wilhelm Bunsen and Gustav Robert Kirchhoff, both professors at the University of Heidelberg, Germany. The modern form of AAS was largely developed during the 1950s by a team of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Byzantine
The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in Europe. The terms "Byzantine Empire" and "Eastern Roman Empire" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire, and to themselves as Romans—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued and its traditions were maintained, modern historians prefer to differentiate the Byzantine Empire from Ancient R ...

Ulu Burun
The Uluburun Shipwreck is a Late Bronze Age shipwreck dated to the late 14th century BC, discovered close to the east shore of Uluburun (Grand Cape), Turkey, in the Mediterranean Sea. The shipwreck was discovered in the summer of 1982 by Mehmed Çakir, a local sponge diver from Yalıkavak, a village near Bodrum. Eleven consecutive campaigns of three to four months' duration took place from 1984 to 1994 totaling 22,413 dives, revealing one of the most spectacular Late Bronze Age assemblages to have emerged from the Mediterranean Sea. Discovery The shipwreck site was discovered in the summer of 1982 due to Mehmet Çakir's sketching of “the metal biscuits with ears” recognized as oxhide ingots. Turkish sponge divers were often consulted by the Institute of Nautical Archaeology's (INA) survey team on how to identify ancient wrecks while diving for sponges. Çakir's findings urged Oğuz Alpözen, Director of the Bodrum Museum of Underwater Archaeology, to send out an inspection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beth She’Arim
Beit She'arim ( he, בֵּית שְׁעָרִים, "House of Gates") is the currently used name for the ancient Jewish town of Bet She'arayim (, "House of Two Gates") or ''Kfar She'arayim'' (, "Village of Two Gates"),Sharon (2004), p.XXXVII/ref> made popular by its necropolis, now known as Beit She'arim National Park. The site, located on a hill, was known initially by its Arabic name Sheikh Ibreik or Sheikh Abreik, purchased by the Jewish National Fund, and which historical geographer Samuel Klein in 1936 identified as Talmudic Beit She'arim. The partially excavated archaeological site consists mainly of an extensive necropolis of rock-cut tombs and some remains of the town itself. The site is managed by the National Parks Authority.

Manganese
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems. It is a critical component in dozens of proteins and enzymes. It is found mostly in the bones, but also the liver, kidneys, and brain. In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. Manganese was first isolated in 1774. It is familiar in the laboratory in the form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromophore
A chromophore is the part of a molecule responsible for its color. The color that is seen by our eyes is the one not absorbed by the reflecting object within a certain wavelength spectrum of visible light. The chromophore is a region in the molecule where the energy difference between two separate molecular orbitals falls within the range of the visible spectrum. Visible light that hits the chromophore can thus be absorbed by exciting an electron from its ground state into an excited state. In biological molecules that serve to capture or detect light energy, the chromophore is the moiety that causes a conformational change in the molecule when hit by light. Conjugated pi-bond system chromophores Just like how two adjacent p-orbitals in a molecule will form a pi-bond, three or more adjacent p-orbitals in a molecule can form a conjugated pi-system. In a conjugated pi-system, electrons are able to capture certain photons as the electrons resonate along a certain distanc ...

Redox
Redox (reduction–oxidation, , ) is a type of chemical reaction in which the oxidation states of substrate (chemistry), substrate change. Oxidation is the loss of Electron, electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. There are two classes of redox reactions: * ''Electron-transfer'' – Only one (usually) electron flows from the reducing agent to the oxidant. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * ''Atom transfer'' – An atom transfers from one substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously the oxidation state of oxygen decreases as it accepts electrons released by the iron. Although oxidation reactions are commonly associated with the formation of oxides, other chemical species can serve the same function. In hydrogen ...
