Cultural Property Imaging
Cultural property imaging is a necessary part of long term preservation of cultural heritage. While the physical conditions of objects will change over time, imaging serves as a way to document and represent heritage in a moment in time of the life of the item. Different methods of imaging produce results that are applicable in various circumstances. Not every method is appropriate for every object, and not every object needs to be imaged by multiple methods. In addition to preservation and conservation-related concerns, imaging can also serve to enhance research and study of cultural heritage. Purpose One reason for imaging objects is to make the items available for study and scholarship without incurring unnecessary harm to the object. In addition to providing images to scholars, images can also be added to online catalogs and databases to increase the size of the audience interacting with the objects and allow them to view the item with no added risk. Another reason is for doc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultural Heritage
Cultural heritage is the heritage of tangible and intangible heritage assets of a group or society that is inherited from past generations. Not all heritages of past generations are "heritage"; rather, heritage is a product of selection by society. Cultural heritage includes cultural property, tangible culture (such as buildings, monuments, landscapes, archive materials, books, works of art, and artifacts), intangible heritage, intangible culture (such as folklore, traditions, language, and knowledge), and natural heritage (including culturally significant landscapes, and biodiversity).Ann Marie Sullivan, Cultural Heritage & New Media: A Future for the Past, 15 J. MARSHALL REV. INTELL. PROP. L. 604 (2016) https://repository.jmls.edu/cgi/viewcontent.cgi?article=1392&context=ripl The term is often used in connection with issues relating to the protection of Indigenous intellectual property.

Reflectance Transformation Imaging
Polynomial texture mapping (PTM), also known as Reflectance Transformation Imaging (RTI), is a technique of imaging and interactively displaying objects under varying lighting conditions to reveal surface phenomena. The data acquisition method is Single Camera Multi Light (SCML). Origins The method was originally developed by Tom Malzbender of HP Labs in order to generate enhanced 3D computer graphics and it has since been adopted for cultural heritage applications. Methodology A series of images is captured in a darkened environment with the camera in a fixed position and the object lit from different angles (Single Camera Multi Light). Interactive software processes and combines the set of images to enable the user inspecting the object to control a virtual light source. The virtual light source may be manipulated to simulate light from different angles and of different intensity or wavelengths to illuminate the surface of artefacts and reveal details. Open-source tools for pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collections Care
Disaster preparedness in museums, galleries, libraries, archives and private collections, involves any actions taken to plan for, prevent, respond or recover from natural disasters and other events that can cause damage or loss to cultural property. 'Disasters' in this context may include large-scale natural events such as earthquakes, flooding or bushfire, as well as human-caused events such as theft and vandalism. Increasingly, anthropogenic climate change is a factor in cultural heritage disaster planning, due to rising sea levels, changes in rainfall patterns, warming average temperatures, and more frequent extreme weather events. The primary goal of disaster preparedness is to identify actions that can be taken to reduce either the chance of a disaster occurring or to lessen its effects. For example, clearing building gutters reduces the chance of overflow and leaks during heavy rainfall; storing collection objects inside closed cabinets reduces the chance of water damage sh ...

Conservation And Restoration Of Cultural Heritage
conservation and restoration of cultural property focuses on protection and care of cultural property (tangible cultural heritage), including artworks, architecture, archaeology, and museum collections. Conservation activities include preventive conservation, examination, documentation, research, treatment, and education. This field is closely allied with conservation science, curators and registrars. Definition Conservation of cultural property involves protection and restoration using "any methods that prove effective in keeping that property in as close to its original condition as possible for as long as possible." Conservation of cultural heritage is often associated with art collections and museums and involves collection care and management through tracking, examination, documentation, exhibition, storage, preventive conservation, and restoration. The scope has widened from art conservation, involving protection and care of artwork and architecture, to conservat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
En-Gedi Scroll
The En-Gedi Scroll, also called the En-Gedi Leviticus Scroll (EGLev) is an ancient Hebrew parchment found in 1970 at Ein Gedi, Israel. Radiocarbon testing dates the scroll to the third or fourth century CE (88.9% certainty for 210–390 CE), although there is disagreement over whether the evidence from the writing itself supports that date. The scroll was discovered to contain a portion of the biblical Book of Leviticus, making it the earliest copy of a Pentateuchal book ever found in a Torah ark. The deciphered text fragment is identical to what was to become, during the Middle Ages, the standard text of the Hebrew Bible, known as the Masoretic Text, which it precedes by several centuries. Damaged by a fire in approximately 600 CE, the scroll is badly charred and fragmented and required noninvasive scientific and computational techniques to virtually unwrap and read, which was completed in 2015 by a team led by Brent Seales of the University of Kentucky. Dating Radiocarbon dat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archimedes Palimpsest
The Archimedes Palimpsest is a parchment codex palimpsest, originally a Byzantine Greek copy of a compilation of Archimedes and other authors. It contains two works of Archimedes that were thought to have been lost (the '' Ostomachion'' and the '' Method of Mechanical Theorems'') and the only surviving original Greek edition of his work '' On Floating Bodies''. The first version of the compilation is believed to have been produced by Isidore of Miletus, the architect of the geometrically complex Hagia Sophia cathedral in Constantinople, sometime around AD 530. The copy found in the palimpsest was created from this original, also in Constantinople, during the Macedonian Renaissance (c. AD 950), a time when mathematics in the capital was being revived by the former Greek Orthodox bishop of Thessaloniki Leo the Geometer, a cousin of the Patriarch. Following the sack of Constantinople by Western crusaders in 1204, the manuscript was taken to an isolated Greek monastery in Palest ...

Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (PET) scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy. MRI is widely used in hospitals and clinics for medical diagnosis, staging and follow-up of disease. Compared to CT, MRI provides better contrast in images of soft tissues, e.g. in the brain or abdomen. However, it may be perceived as less comfortable by patients, due to the usually longer and louder measurements with the subject in a long, confining tube, although ...

Natural History Museum, London
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum (London), Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in Taxonomy (biology), taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the ...

CT Scan
A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists. CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry (medical), gantry to measure X-ray Attenuation#Radiography, attenuations by different tissues inside the body. The multiple X-ray measurements taken from different angles are then processed on a computer using tomographic reconstruction algorithms to produce Tomography, tomographic (cross-sectional) images (virtual "slices") of a body. CT scans can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is Contraindication, contraindicated. Since its development in the 1970s, CT scanning has proven to be a versatile imaging technique. While CT is most prominently used in medical diagnosis, i ...

Ghent Altarpiece
The ''Ghent Altarpiece'', also called the ''Adoration of the Mystic Lamb'' (), is a very large and complex 15th-century polyptych altarpiece in St Bavo's Cathedral, Ghent, Belgium. It was begun around the mid-1420s and completed by 1432, and it is attributed to the Early Netherlandish painting, Early Netherlandish painters and brothers Hubert van Eyck, Hubert and Jan van Eyck. The altarpiece is a prominent example of the transition from Middle Age to Renaissance art and is considered a masterpiece of European art, identified by some as "the first major oil painting." The panels are organised in two vertical Register (art), registers, each with double sets of foldable wings containing inner and outer panel paintings. The upper register of the inner panels represents the heavenly redemption, and includes the central classical ''Deësis'' arrangement of God (identified either as Jesus, Christ the King or God the Father), flanked by the Blessed Virgin Mary, Virgin Mary and John the ...

Herculaneum Papyri
The Herculaneum papyri are more than 1,800 papyrus scrolls discovered in the 18th century in the Villa of the Papyri in Herculaneum. They had been Carbonization, carbonized when the villa was engulfed by the eruption of Mount Vesuvius in 79 AD. The papyri, containing a number of Greek Philosophy, Greek philosophical texts, come from the only surviving library from antiquity that exists in its entirety.Interview with Daniel Delattre: the Herculaneum scrolls given to Consul Bonaparte (2010), Napoleon.org However, reading the scrolls is extremely difficult, and can risk destroying them. The evolution of techniques to do this continues. The majority of classical texts referred to by other classical authors are lo ...

Radiography
Radiography is an imaging technology, imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical ("diagnostic" radiography and "therapeutic radiography") and industrial radiography. Similar techniques are used in airport security, (where "body scanners" generally use backscatter X-ray). To create an image in conventional radiography, a beam of X-rays is produced by an X-ray generator and it is projected towards the object. A certain amount of the X-rays or other radiation are absorbed by the object, dependent on the object's density and structural composition. The X-rays that pass through the object are captured behind the object by a X-ray detector, detector (either photographic film or a digital detector). The generation of flat two-dimensional images by this technique is called Projection radiography, projectional radiography. In computed tomography (C ...
