New Zealand Forest Research Institute
Scion, officially registered as New Zealand Forest Research Institute Limited, is a New Zealand Crown Research Institute with its primary areas of research, science and technology development being in the areas of forestry, wood products, wood-derived materials and other biomaterials sectors. History The organisation was established in April 1947 as part of the New Zealand Forest Service, originally named the Forest Experiment Station. Its early research included work on timber drying, preservation and fibre production that remains relevant in the 21st century. In the 1960s the organisation undertook intensive forest pathology research following the spread of red band needle blight among New Zealand pine trees. It undertook research in the 1970s into growing trees as crops, including improving techniques for mass production of seedlings and trials of growing trees on fertile farmland. In 1987 the organisation became part of the new Ministry of Forestry. It became a Crown Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotorua, New Zealand
Rotorua () is a city in the Bay of Plenty region of New Zealand's North Island. The city lies on the southern shores of Lake Rotorua, from which it takes its name. It is the seat of the Rotorua Lakes District, a territorial authority encompassing Rotorua and several other nearby towns. Rotorua has an estimated resident population of , making it the country's 12th largest urban area, and the Bay of Plenty's second largest urban area behind Tauranga.

Forest Inventory
Forest inventory is the systematic collection of data and forest information for assessment or analysis. An estimate of the value and possible uses of timber is an important part of the broader information required to sustain ecosystems. When taking forest inventory the following are important things to measure and note: species, diameter at breast height (DBH), height, site quality, age, and defects. From the data collected one can calculate the number of trees per acre, the basal area, the volume of trees in an area, and the value of the timber. Inventories can be done for other reasons than just calculating the value. A forest can be cruised to visually assess timber and determine potential fire hazards and the risk of fire. The results of this type of inventory can be used in preventive actions and also awareness. Wildlife surveys can be undertaken in conjunction with timber inventory to determine the number and type of wildlife within a forest. The aim of the statistical fore ...

Forest Research Institutes
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Crown Research Institutes Of New Zealand
A crown is a traditional form of head adornment, or hat, worn by monarchs as a symbol of their power and dignity. A crown is often, by extension, a symbol of the monarch's government or items endorsed by it. The word itself is used, particularly in Commonwealth countries, as an abstract name for the monarchy itself, as distinct from the individual who inhabits it (that is, ''The Crown''). A specific type of crown (or coronet for lower ranks of peerage) is employed in heraldry under strict rules. Indeed, some monarchies never had a physical crown, just a heraldic representation, as in the constitutional kingdom of Belgium, where no coronation ever took place; the royal installation is done by a solemn oath in parliament, wearing a military uniform: the King is not acknowledged as by divine right, but assumes the only hereditary public office in the service of the law; so he in turn will swear in all members of "his" federal government''.

Wellington
Wellington ( mi, Te Whanganui-a-Tara or ) is the capital city of New Zealand. It is located at the south-western tip of the North Island, between Cook Strait and the Remutaka Range. Wellington is the second-largest city in New Zealand by metro area, and is the administrative centre of the Wellington Region. It is the world's southernmost capital of a sovereign state. Wellington features a temperate maritime climate, and is the world's windiest city by average wind speed. Legends recount that Kupe discovered and explored the region in about the 10th century, with initial settlement by Māori iwi such as Rangitāne and Muaūpoko. The disruptions of the Musket Wars led to them being overwhelmed by northern iwi such as Te Āti Awa by the early 19th century. Wellington's current form was originally designed by Captain William Mein Smith, the first Surveyor General for Edward Wakefield's New Zealand Company, in 1840. The Wellington urban area, which only includes urbanised ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christchurch
Christchurch ( ; mi, Ōtautahi) is the largest city in the South Island of New Zealand and the seat of the Canterbury Region. Christchurch lies on the South Island's east coast, just north of Banks Peninsula on Pegasus Bay. The Avon River / Ōtākaro flows through the centre of the city, with an urban park along its banks.

Tangata Whenua
In New Zealand, tangata whenua () is a Māori term that literally means "people of the land". It can refer to either a specific group of people with historical claims to a district, or more broadly the Māori people as a whole. Etymology According to Williams' definitive ''Dictionary of the Māori Language'', ''tangata'' means "man" or "human being", whilst ''tāngata'' (with the macronated "ā") is the plural, and means "people". ''Tangata''—without the macron—can also mean "people" in reference to a group with a singular identity. ''Whenua'' means both "land" and "placenta" (again referencing Williams, who lists five definitions). It is an ancient Austronesian word with cognates across the Malayo-Polynesian world, from Malay ''benua'' (now meaning "continent"), Visayan *''banwa'' and to Rapa Nui ''henua''; ultimately from Proto-Austronesian *''banua''. Unlike European thought, wherein people own land, in the Māori worldview the land is regarded as a mother to the people. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carbon Nanofibre
Carbon nanofibers (CNFs), vapor grown carbon fibers (VGCFs), or vapor grown carbon nanofibers (VGCNFs) are cylindrical nanostructures with graphene layers arranged as stacked cone (geometry), cones, cups or plates. Carbon nanofibers with graphene layers wrapped into perfect cylinders are called carbon nanotubes. Introduction Carbon has a high level of chemical bonding flexibility, which lends itself to the formation of a number of stable Organic and Inorganic Molecules. Elemental carbon has a number of allotropes(variants) including diamond, graphite, and fullerenes.Morgan, P. (2005) ''Carbon Fibers and Their Composites'', Taylor & Francis Group, CRC Press, Boca Raton, FL. Though they all consist of elemental carbon, their properties vary widely. This underscores the versatility of CNFs, which are notable for their thermal, electrical, electromagnetic shielding, and mechanical property enhancements. As carbon is readily available at low cost, CNFs are popular additives to co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unmanned Aerial Vehicles
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Tra ...
