Conservation And Restoration Of Wooden Artifacts
The conservation and restoration of wooden artifacts refers to the preservation of art and artifacts made of wood. Conservation and restoration in regards to cultural heritage is completed by a conservator-restorer. See also Conservation and restoration of wooden furniture Nature of the material Wood is a vascular material that comes from the trunk, roots, or stems of over 3,000 varieties of plants.. It is a cellular tissue and therefore can be understood by looking into the biological structure. Cell structure Wood is porous and its growth is directional. This is due to the cellular structure of the material. Cellular structure determines factors such as grain, texture, and color. Identification of wood types is undertaken by a conservation scientist. Grain Wood grain is created by the variations in number and arrangement of cells. It specifically refers to the longitudinal alignment of cells, or the direction in which the fibers are going. The six types of grain are: straight, ... [...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, 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.

Alkalies
In chemistry, an alkali (; from ar, القلوي, al-qaly, lit=ashes of the saltwort) is a basic, ionic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases. Etymology The word "alkali" is derived from Arabic ''al qalīy'' (or ''alkali''), meaning ''the calcined ashes'' (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly of potassium carbonate, was mildly basic. After heating this substance with calcium hydroxide (''slaked lim ...

Temperature
Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer. Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called ''centigrade''), the Fahrenheit scale (°F), and the Kelvin scale (K), the latter being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI). Absolute zero, i.e., zero kelvin or −273.15 °C, is the lowest point in the thermodynamic temperature scale. Experimentally, it can be approached very closely but not actually reached, as recognized in the third law of thermodynamics. It would be impossible to extract energy as heat from a body at that temperature. Temperature is important in all fields of natur ...

Art Handler
An art handler, also sometimes called an art preparator, is a trained individual who works directly with objects in museums, art galleries and various other venues including private collectors, corporate art collections, public art collections and various other institutions. Art handlers work in coordination with registrars, collection managers, conservator-restorers, exhibition designers, and curators, among others, to ensure that objects are safely handled and cared for. Often they are responsible for packing and unpacking art, installing and deinstalling art in exhibitions, and moving art around the museum and storage spaces. They are an integral part of a museum and collections care.Schlatter, N. E. (2008). Jobs Focused on Objects and/or Exhibitions. Museum careers: a practical guide for novices and students (pp. 70-71).

Registrar (museum)
A museum/library/archival registrar is responsible for implementing policies and procedures that relate to caring for collections of cultural institutions like archives, libraries, and museums. These policies are found in the museum's collections policy, the guiding tenet of the museum explaining why the institution is in operation, dictating the museum's professional standards regarding the objects left in its care. Registrars focus on sections that include acquisitions, loans, exhibitions, deaccessions, storage, packing and shipping, security of objects in transit, insurance policies, and risk management. As a collections care professional, they work with collection managers, conservators, and curators to balance public access to objects with the conditions needed to maintain preservation. Focusing on documentation, registrars are responsible for developing and maintaining records management systems, with individual files for each object in the collection. Smaller and mid-si ...

Collection Manager
A collection manager ensures the proper care and preservation of objects within cultural institutions such as museums, libraries, and archives. Collection managers, along with registrars, curators, and conservators, play an important role in collections care. Collection Managers and Registrars are two distinct collection roles that are often combined into one within small to mid-size cultural institutions. Collection Managers can be found in large museums and those with a history and natural history focus whose diverse collections require experienced assessment to properly sort, catalog, and store artifacts. A collection manager may oversee the registrar, archivist, curator, photographer, or other collection professionals, and may assume the responsibilities of these roles in their absence within an organization. Differences between collection managers and registrars Collection managers are responsible for the long-term preservation of collections. They oversee the physical care ...

Rodents
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose incisors ...

Marine Life
Marine life, sea life, or ocean life is the plants, animals and other organisms that live in the salt water of seas or oceans, or the brackish water of coastal estuaries. At a fundamental level, marine life affects the nature of the planet. Marine organisms, mostly microorganisms, produce oxygen and sequester carbon. Marine life in part shape and protect shorelines, and some marine organisms even help create new land (e.g. coral building reefs). Most life forms evolved initially in marine habitats. By volume, oceans provide about 90% of the living space on the planet. The earliest vertebrates appeared in the form of fish, which live exclusively in water. Some of these evolved into amphibians, which spend portions of their lives in water and portions on land. One group of amphibians evolved into reptiles and mammals and a few subsets of each returned to the ocean as sea snakes, sea turtles, seals, manatees, and whales. Plant forms such as kelp and other algae grow in the wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodpeckers
Woodpeckers are part of the bird family Picidae, which also includes the piculets, wrynecks, and sapsuckers. Members of this family are found worldwide, except for Australia, New Guinea, New Zealand, Madagascar, and the extreme polar regions. Most species live in forests or woodland habitats, although a few species are known that live in treeless areas, such as rocky hillsides and deserts, and the Gila woodpecker specialises in exploiting cacti. Members of this family are chiefly known for their characteristic behaviour. They mostly forage for insect prey on the trunks and branches of trees, and often communicate by drumming with their beaks, producing a reverberatory sound that can be heard at some distance. Some species vary their diet with fruits, birds' eggs, small animals, tree sap, human scraps, and carrion. They usually nest and roost in holes that they excavate in tree trunks, and their abandoned holes are of importance to other cavity-nesting birds. They sometimes come ...

Birds
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
