Naval Stores Industry
The naval stores industry collects, processes, and markets forest products refined from the oleoresin of the slash pine and longleaf pine trees (genus ''Pinus''). The industry was associated with the maintenance of the wooden ships and sailing tackle of pre-20th century navies, which were caulked and waterproofed using the pitch (a product made with tar) of the pine tree. History With the demise of wooden ships, those uses of pine resin ended, but the industry remained vigorous as new products created new markets. First extensively described by Frederick Law Olmsted in his book ''A Journey in the Seaboard Slave States'' (1856), the naval stores industry was one of the economic mainstays of the southeastern United States until the late 20th century. Despite a rapid decline of the gum naval stores industry in the last quarter of the 20th century, a few places in the southeastern United States still rely on it as a major part of their livelihood. Gum naval stores cultivation ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transshipment
Transshipment, trans-shipment or transhipment is the shipment of goods or containers to an intermediate destination, then to another destination. One possible reason for transshipment is to change the means of transport during the journey (e.g., from ship transport to road transport), known as transloading. Another reason is to combine small shipments into a large shipment (consolidation), or the opposite: dividing a large shipment into smaller shipments (deconsolidation). Transshipment usually takes place in transport hubs. Much international transshipment also takes place in designated customs areas, thus avoiding the need for customs checks or duties, otherwise a major hindrance for efficient transport. An item handled (from the shipper's point of view) as a single movement is not generally considered transshipped, even if it changes from one mode of transport to another at several points. Previously, it was often not distinguished from transloading, since each leg of such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forestry
Forestry is the science and craft of creating, managing, planting, using, conserving and repairing forests, woodlands, and associated resources for human and environmental benefits. Forestry is practiced in plantations and natural stands. The science of forestry has elements that belong to the biological, physical, social, political and managerial sciences. Forest management play essential role of creation and modification of habitats and affect ecosystem services provisioning. Modern forestry generally embraces a broad range of concerns, in what is known as multiple-use management, including: the provision of timber, fuel wood, wildlife habitat, natural water quality management, recreation, landscape and community protection, employment, aesthetically appealing landscapes, biodiversity management, watershed management, erosion control, and preserving forests as " sinks" for atmospheric carbon dioxide. Forest ecosystems have come to be seen as the most important componen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maritime History
Maritime history is the study of human interaction with and activity at sea. It covers a broad thematic element of history that often uses a global approach, although national and regional histories remain predominant. As an academic subject, it often crosses the boundaries of standard Academic discipline, disciplines, focusing on understanding humankind's various relationships to the oceans, list of seas, seas, and major waterways of the globe. Nautical history records and interprets past events involving ships, shipping, navigation, and seafarers. Maritime history is the broad overarching subject that includes fishing, whaling, international maritime law, naval history, the history of ships, ship design, shipbuilding, the history of navigation, the history of the various maritime-related sciences (oceanography, cartography, hydrography, etc.), sea exploration, maritime economics and trade, shipping, yachting, seaside resorts, the history of lighthouses and aids to navigation, ma ...

Shipbuilding
Shipbuilding is the construction of ships and other floating vessels. It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history. Shipbuilding and ship repairs, both commercial and military, are referred to as "naval engineering". The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking. History Pre-history The earliest known depictions (including paintings and models) of shallow-water sailing boats is from the 6th to 5th millennium BC of the Ubaid period of Mesopotamia. They were made from bundled reeds coated in bitumen and had bipod masts. They sailed in shallow coastal waters of the Persian Gulf. 4th millennium BC Ancient Egypt Evidence from Ancient Egypt shows that the early Egyptians knew how to assemble planks of wood into a ship hull as early as 3100 BC.

Non-timber Forest Product
Non-timber forest products (NTFPs) are useful foods, substances, materials and/or commodities obtained from forests other than timber. Harvest ranges from wild collection to farming. They typically include game animals, fur-bearers, nuts, seeds, berries, mushrooms, oils, sap, foliage, pollarding, medicinal plants, peat, mast, fuelwood, fish, insects, spices, and forage. Overlapping concepts include non-wood forest products (NWFPs), wild forest products, minor forest produce, special, minor, alternative and secondary forest products – for further distinctions see the definition section below Research on NTFPs has focused on their ability to be produced as commodities for rural incomes and markets, as an expression of traditional knowledge or as a livelihood option for rural household needs, as a key component of sustainable forest management and conservation strategies, and for their important role in improving dietary diversity and providing nutritious food, particularly f ...

McCranie's Turpentine Still
McCranie's Turpentine Still is a historic site in Willacoochee, Georgia.''McCranie's Turpentine Still'', by Kenneth H. Thomas Jr., The University of Georgia Institute of Community & Area Development and Georgia Department of Natural Resources, 1975. It was added to the National Register of Historic Places on June 28, 1976. It is located west of Willacoochee on U.S. 82. History The McCranie family worked in the turpentine industry prior to 1900 and continued for generations. This turpentine still was built in 1936, based on designs and methods from earlier eras. It was operated by three McCranie brothers. It ceased operation in 1942 when the two elder McCranie brothers went to war. The replacement of the fire distillation process by steam distillation and the labor shortage caused by World War II contributed to its closure. The still remains largely intact.

Byproduct
A by-product or byproduct is a secondary product derived from a production process, manufacturing process or chemical reaction; it is not the primary product or service being produced. A by-product can be useful and marketable or it can be considered waste: for example, bran, which is a byproduct of the milling of wheat into refined flour, is sometimes composted or burned for disposal, but in other cases, it can be used as a nutritious ingredient in human food or animal feed. Gasoline was once a byproduct of oil refining that later became a desirable commodity as motor fuel. The plastic used in plastic shopping bags also started as a by-product of oil refining. In economics In the context of production, a by-product is the "output from a joint production process that is minor in quantity and/or net realizable value (NRV) when compared with the main products". Because they are deemed to have no influence on reported financial results, by-products do not receive allocations of j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Filtered Rosin Products
Filtration is a physical separation process that separates solid matter and fluid from a mixture using a ''filter medium'' that has a complex structure through which only the fluid can pass. Solid particles that cannot pass through the filter medium are described as ''oversize'' and the fluid that passes through is called the ''filtrate''. Oversize particles may form a filter cake on top of the filter and may also block the filter lattice, preventing the fluid phase from crossing the filter, known as ''blinding''. The size of the largest particles that can successfully pass through a filter is called the effective ''pore size'' of that filter. The separation of solid and fluid is imperfect; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size, filter thickness and biological activity). Filtration occurs both in nature and in engineered systems; there are biological, geological, and industrial forms. Filtration is also ...

Varnish
Varnish is a clear transparent hard protective coating or film. It is not a stain. It usually has a yellowish shade from the manufacturing process and materials used, but it may also be pigmented as desired, and is sold commercially in various shades. Varnish is primarily used as a wood finish where, stained or not, the distinctive tones and grains in the wood are intended to be visible. Varnish finishes are naturally glossy, but satin/semi-gloss and flat sheens are available. History The word "varnish" comes from Mediaeval Latin ''vernix'', meaning odorous resin, itself derived from Middle Greek ''berōnikón'' or ''beroníkē'', meaning amber or amber-colored glass. A false etymology traces the word to the Greek ''Berenice'', the ancient name of modern Benghazi in Libya, where the first varnishes in the Mediterranean area were supposedly used and where resins from the trees of now-vanished forests were sold. Early varnishes were developed by mixing resin—pine sap, for ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
