Australian Aboriginal Artefacts
Australian Aboriginal artefacts include a variety of cultural artefacts used by Aboriginal Australians. Most Aboriginal artefacts were multi-purpose and could be used for a variety of different occupations. Spears, Waddy, clubs, boomerangs and Hielaman, shields were used generally as weapons for hunting and in warfare. Watercraft technology artefacts in the form of Dugout canoe, dugout and bark canoes were used for transport and for fishing. Stone artefacts include cutting tools and grinding stones to hunt and make food. Coolamon (vessel), Coolamons and carriers such as dillybags, allowed Aboriginal peoples to carry water, food and cradle babies. Message sticks were used for communication, and ornamental artefacts for decorative and ceremonial purposes. Aboriginal children’s toys were used to both entertain and educate. Weapons Aboriginal peoples used several different types of weapons including shields (also known as hielaman), spears, spear-throwers, boomerangs and clubs. ...

Spear
A spear is a polearm consisting of a shaft, usually of wood, with a pointed head. The head may be simply the sharpened end of the shaft itself, as is the case with Fire hardening, fire hardened spears, or it may be made of a more durable material fastened to the shaft, such as bone, flint, obsidian, copper, bronze, iron, or steel. The most common design for hunting and/or warfare, since modern times has incorporated a metal spearhead shaped like a triangle, lozenge (shape), diamond, or Glossary of leaf morphology, leaf. The heads of fishing spears usually feature multiple sharp Tine (structural), points, with or without barbs. Spears can be divided into two broad categories: those designed for thrusting as a melee weapon (including weapons such as lances and Pike (weapon), pikes) and those designed for throwing as a ranged weapon (usually referred to as javelins). The spear has been used throughout human history as a weapon for hunting and/or fishing and for warfare. Along with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia Oswaldii
''Acacia oswaldii'', commonly known as boree, umbrella wattle, umbrella bush, whyacka, middia, miljee, nelia and curly yarran, is a shrub or tree of the genus ''Acacia'' and the subgenus ''Plurinerves''. Description The shrub or tree typically grows to a height of and can be found to . It has terete and glabrousness (botany), glabrous branchlets with many red, resinous micro-hairs. Phyllodes are spreading to erect with leaves that are linear, narrowly elliptic or narrowly oblong-elliptic shape that is straight to recurved, terete to flat, in length and wide. Leaves are hairy when young, becoming hairless, edges smooth, with a straight often sharp point. It blooms from October to December and produces yellow flowers. The simple inflorescences forms singly or in pairs in the axil of the phyllodes supported on hairy peduncles that are long. The flowers are heads globose holding 5 to 16-flowers that are in diameter. Seed pods form later that are curved or coiled and mostly flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia Estrophiolata
''Acacia estrophiolata'', commonly known as ironwood, southern ironwood, desert ironwood or utjanypa, is a tree native to Central Australia. Description It is a graceful, pendulous shade tree, which grows from about tall and has a trunk with a diameter of up to about 0.45 m. It has a spreading crown that becomes weeping as the tree matures. Young plants have rigid branches and short straight phyllodes that appear in clusters. As trees mature the branches become pendulous and the light green, spiky phyllodes increase in length but are no longer clustered. It has a heavy bloom of spherical pale yellow flowers after winter rains. The tree has a slow growth rate and is both drought and frost tolerant. Taxonomy The species was first formally described by botanist Ferdinand von Mueller in 1882 as part of the work ''Definitions of some new Australian plants'' as published in ''Southern Science Record''. It was reclassified as ''Racosperma estrophiolatum'' by Leslie Pedley in 1987 then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia
''Acacia'', commonly known as wattles or acacias, is a genus of about of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa, South America, and Australasia, but is now reserved for species mainly from Australia, with others from New Guinea, Southeast Asia, and the Indian Ocean. The genus name is Neo-Latin, borrowed from Koine Greek (), a term used in antiquity to describe a preparation extracted from '' Vachellia nilotica'', the original type species. Several species of ''Acacia'' have been introduced to various parts of the world, and two million hectares of commercial plantations have been established. Description Plants in the genus ''Acacia'' are shrubs or trees with bipinnate leaves, the mature leaves sometimes reduced to phyllodes or rarely absent. There are 2 small stipules at the base of the leaf, but sometimes fall off as the leaf matures. The flowers are borne in spik ...

Waddy
A waddy, nulla-nulla, leangle or boondi is an Aboriginal Australian hardwood club or hunting stick for use as a weapon or as a throwing stick for hunting animals. ''Waddy'' comes from the Darug people of Port Jackson, Sydney.Peters, Pam, ''The Cambridge Australian English Style Guide'', Cambridge University Press, 1995, ''Boondi'' is the Wiradjuri word for this implement. Leangle is a Djadjawurrung word for a club with a hooked striking head. Description and use A waddy is a heavy pointed club constructed of carved hardwood timber; it was a traditional weapon developed by Aboriginal people in Australia. Waddies were used in hand-to-hand combat and were capable of splitting a shield. They could also kill or stun a prey. They could be used as projectiles or to make fire and make ochre Ochre ( ; , ), iron ochre, or ocher in American English, is a natural clay earth pigment, a mixture of ferric oxide and varying amounts of clay and sand. It ranges in colour from yellow t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinew
A tendon or sinew is a tough band of dense fibrous connective tissue that connects muscle to bone. It sends the mechanical forces of muscle contraction to the skeletal system, while withstanding tension. Tendons, like ligaments, are made of collagen. The difference is that ligaments connect bone to bone, while tendons connect muscle to bone. There are about 4,000 tendons in the adult human body. Structure A tendon is made of dense regular connective tissue, whose main cellular components are special fibroblasts called tendon cells (tenocytes). Tendon cells synthesize the tendon's extracellular matrix, which abounds with densely-packed collagen fibers. The collagen fibers run parallel to each other and are grouped into fascicles. Each fascicle is bound by an endotendineum, which is a delicate loose connective tissue containing thin collagen fibrils and elastic fibers. A set of fascicles is bound by an epitenon, which is a sheath of dense irregular connective tissue. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Fibre
Fiber crops are field crops grown for their fibers, which are traditionally used to make paper, cloth, or rope. Fiber crops are characterized by having a large concentration of cellulose, which is what gives them their strength. The fibers may be chemically modified, like in viscose (used to make rayon and cellophane). In recent years, materials scientists have begun exploring further use of these fibers in composite materials. Due to cellulose being the main factor of a plant fiber's strength, this is what scientists are looking to manipulate to create different types of fibers. Fiber crops are generally harvestable after a single growing season, as distinct from trees, which are typically grown for many years before being harvested for such materials as wood pulp fiber or lacebark. In specific circumstances, fiber crops can be superior to wood pulp fiber in terms of technical performance, environmental impact or cost. There are a number of issues regarding the use of fiber ...

Mastic (plant Resin)
Mastic () is a resin obtained from the mastic tree (''Pistacia lentiscus''). It is also known as tears of Chios, being traditionally produced on the island of Chios, and, like other natural resins, is produced in "tears" or droplets. Mastic is excreted by the resin glands of the evergreen shrub ''Pistacia lentiscus'' and dries into pieces of brittle, translucent resin. When chewed, the resin softens and becomes a bright white and opaque gum. The flavor is bitter at first, but after some chewing, it releases a refreshing flavor similar to pine and Cedrus, cedar. History Chios mastic gum has been used as a traditional medicine over the last 2,500 years. The word ''mastic'' is derived indirectly from , which may be related to . * Remarks not in the book: OED does not claim came from , it only refers ("cf.") to the latter word for comparison. The first mention of actual mastic 'tears' was by Hippocrates. Hippocrates used mastic for the prevention of digestive problems, colds and a ...

Lithic Flake
In archaeology, a lithic flake is a "portion of rock (geology), rock removed from an objective piece by percussion or pressure,"Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press and may also be referred to as simply a ''flake'', or collectively as debitage. The objective piece, or the rock being reduced by the removal of flakes, is known as a lithic core, core.Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press Once the proper tool stone has been selected, a percussor or pressure flaker (e.g., an antler Tine (structural), tine) is used to direct a sharp blow, or apply sufficient force, respectively, to the surface of the stone, often on the edge of the piece. The energy of this blow propagates through the material, often (termination type, but not always) producing a Hertzian cone of force which causes the rock to fracture in a controllable fashion.

Softwood
Scots pine, a typical and well-known softwood Softwood is wood from gymnosperm trees such as conifers. The term is opposed to hardwood, which is the wood from angiosperm trees. The main differences between hardwoods and softwoods is that the softwoods completely lack vessels (pores). The main softwood species (pines, spruces, larches, false tsugas) also have resin canals (or ducts) in their structure. Characteristics Softwood is wood from gymnosperm trees such as pines and spruces. Softwoods are not necessarily softer than hardwoods. The hardest hardwoods are much harder than any softwood, but in both groups there is enormous variation with the range of wood hardness of the two groups overlapping. For example, balsa wood, which is a hardwood, is softer than most softwoods, whereas the longleaf pine, Douglas fir, and yew softwoods are much harder than several hardwoods. Several specific natural, macroscopic and microscopic features of wood are used in the identification p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
