Department Of Scientific And Industrial Research (New Zealand)
The Department of Scientific and Industrial Research (DSIR) is a now-defunct government science agency in New Zealand, founded in 1926 and broken into Crown Research Institutes in 1992. Foundation DSIR was founded in 1926 by Ernest Marsden after calls from Ernest Rutherford for government to support education and research and on the back of the Imperial Economic Conference in London in October and November 1923, when various colonies discussed setting up such departments. It initially received funding from sources such as the Empire Marketing Board. The initial plans also included a new agricultural college, to be jointly founded by Auckland and Victoria University Colleges, Palmerston North was chosen as the site for this and it grew to become Massey University. Structure DSIR initially had five divisions: * Grasslands in Palmerston North * Plant Diseases in Auckland * Entomology, attached to the Cawthron Institute in Nelson * Soil Survey (later Soil Bureau) in Taita * Ag ...

Bacterial
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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''.

Wallaceville
Wallaceville is a suburb of Upper Hutt (located in the lower (southern) North Island of New Zealand). It is named after John Howard Wallace, an early New Zealand settler, council politician, businessman and author of one of the first published histories of New Zealand. The suburb is home to the oldest surviving wooden blockhouse in New Zealand, and is served by Wallaceville Railway Station. History The name of Wallaceville was first given to a township of 56 lots of about an acre each in the ''Mungaroa Valley'' that J. H. Wallace sold on 15 January 1868. Access to the township, as well as the rest of the Mungaroa and Whitemans Valley was by a road, later known as Wallaceville Road, that has been built between 1864 and 1867 by the Mungaroa Road Board, of which Wallace was also the chairman. Railway station When the railway line reached Upper Hutt in 1876, Wallaceville railway station became a flag station where the line crossed the Wallaceville road (now Ward Street). Wh ...

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. The city's territorial authority population is people, and includes a number of smaller urban areas as well as rural areas. The population of the urban area is people. Christchurch is the second-largest city by urban area population in New Zealand, after Auckland. It is the major urban area of an emerging sub-region known informally as Greater Christchurch. Notable smaller urban areas within this sub-region include Rangiora and Kaiapoi in Waimakariri District, north of the Waimakariri River, and Rolleston and Lincoln in Selwyn District to the south. The first inhabitants migrated to the area sometime between 1000 and 1250 AD. They hunted moa, which led ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porirua
Porirua, ( mi, Pari-ā-Rua) a city in the Wellington Region of the North Island of New Zealand, is one of the four cities that constitute the Wellington metropolitan area. The name 'Porirua' is a corruption of 'Pari-rua', meaning "the tide sweeping up both reaches". It almost completely surrounds Porirua Harbour at the southern end of the Kapiti Coast. As of Porirua had a population of . Name The name "Porirua" has a Māori origin: it may represent a variant of ''pari-rua'' ("two tides"), a reference to the two arms of the Porirua Harbour. In the 19th century, the name designated a land-registration district that stretched from Kaiwharawhara (or Kaiwara) on the north-west shore of Wellington Harbour northwards to and around Porirua Harbour. The road climbing the hill from Kaiwharawhara towards Ngaio and Khandallah still bears the name "Old Porirua Road". History Tradition holds that, prior to habitation, Kupe was the first visitor to the area, and that he bestowed names of s ...

Biodegradable Waste
Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane or simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes. It mainly includes kitchen waste (spoiled food, trimmings, inedible parts), ash, soil, dung and other plant matter. In waste management, it also includes some inorganic materials which can be decomposed by bacteria. Such materials include gypsum and its products such as plasterboard and other simple sulfates which can be decomposed by sulfate reducing bacteria to yield hydrogen sulfide in anaerobic land-fill conditions. In domestic waste collection, the scope of biodegradable waste may be narrowed to include only those degradable wastes capable of being handled in the local waste handling facilities. Biodegradable waste when not handled properly can have an outsized impact on climate change, especially through meth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wastewater
Wastewater is water generated after the use of freshwater, raw water, drinking water or saline water in a variety of deliberate applications or processes. Another definition of wastewater is "Used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff / storm water, and any sewer inflow or sewer infiltration". In everyday usage, wastewater is commonly a synonym for sewage (also called sewerage, domestic wastewater, or municipal wastewater), which is wastewater that is produced by a community of people. As a generic term wastewater may also be used to describe water containing contaminants accumulated in other settings, such as: * Industrial wastewater: waterborne waste generated from a variety of industrial processes, such as manufacturing operations, mineral extraction, power generation, or water and wastewater treatment. ** Cooling water, released with potential thermal pollution after use to condense steam or reduce machi ...

Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, perma ...

Drinking Water
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure. For those who work in a hot climate, up to a day may be required. Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foodborne Disease
Foodborne illness (also foodborne disease and food poisoning) is any illness resulting from the spoilage of contaminated food by pathogenic bacteria, viruses, or parasites that contaminate food, as well as prions (the agents of mad cow disease), and toxins such as aflatoxins in peanuts, poisonous mushrooms, and various species of beans that have not been boiled for at least 10 minutes. Symptoms vary depending on the cause but often include vomiting, fever, and aches, and may include diarrhea. Bouts of vomiting can be repeated with an extended delay in between, because even if infected food was eliminated from the stomach in the first bout, microbes, like bacteria (if applicable), can pass through the stomach into the intestine and begin to multiply. Some types of microbes stay in the intestine. For contaminants requiring an incubation period, symptoms may not manifest for hours to days, depending on the cause and on quantity of consumption. Longer incubation periods tend to ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
