Natural gas - Essay Example ther a step ahead they transported the crude gas through bamboo shoots to near sea shore, where it was used to distilled sea water to make it suitable for drinking. In early 1626, a French explorer first times discovered and identified natives igniting gases in America that were seeping into and around Lake Erie. In 1821 in Fredonia, United States, a massive escape of gas was observed in form of bubbles rising to the surface from a creek and an American industrialist and financier William Hart, considered as America’s â€Å"father of natural gas,† dug there the first natural gas well in North America. In Europe, natural gas was first come to known around 1659 when it was discovered in Great Britain. The last century technological development probed that major natural gas reservoirs are laying often in conjunction with crude oil, hence in recent times, major natural gas reservoirs were discovered as a result of searching for crude oil (Speight, 9). Since the discovery of natural gas as a heat source by the Chinese about two thousand years ago, the use of natural gas as an energy source has increased tremendously and presently, natural gas is about one quarter of the energy resources of the world (Speight, 21) as shown in fig. 1. The main use of natural gas is combustion. The heat generated due to burning of gas is either directly or indirectly used for various energy purposes. In direct heating, natural gas is utilized both in residential  and  commercial  heating and cooking purposes. Indirectly the heat generated due to natural gas combustion is used to generate electricity by using gas fired generators, steam turbines, gas turbines and combined cycle power generation units. Another important indirect use of heat generated due to combustion of natural gas is its use as transportation fuel by compressing  natural  gas  (CNG) to less than 1% of its volume at standard atmospheric  pressure (Natural gas report, 3). Except these natural gas is used in many

Study Design and Data Collection Strategies Research Paper

Study Design and Data Collection Strategies - Research Paper Example The software and hardware will be used to amalgamate the data that will be drawn from land cover maps, and topographic contour maps. It is assumed that, the database will be effective for integrating data generated internally, and which includes plans for habitat restoration and locations of the habitats. DATA REQUIREMENTS Description Enough of the required data is needed for the development of accurate and comprehensive database of a conservatory. The software to be used will be appropriate for reading topographic contour maps. They will be developed in a way that will make distinguishing of the contour lines easier. This will facilitate connection and determination of points with equal elevation within the required region in the conservatory. By so doing, the management of the conservatory will manage to follow the movement of the endangered species along the contours and, therefore, come up with strategies of protecting them. The software will be remarkably effective in developing the database to be used in recording and handling of the wildlife capacity like for example, bird flocks. The wardens will find it easy to follow and locate the habitats making the management of the threatened species unproblematic. Source: Ronca, (2011) Land cover maps will also be developed after the establishment of the database. Land cover maps are used in an array of spatial resolutions and data formats which suit the users appropriately. They allow for the use of detailed data which can be provided as vector products of at least 0.5 Hectare Map units. Source: Land cover map, 2012 The database with the help of software and hardware will provide data from an approximated distance of one kilometer radius within the conservatory. For geo referencing, LCM 2007, LCM 2000 AND LCM 1990 are used in digital land cover maps. Sources of data The data required for running the database will be received digitally from the satellites located in different areas within the conservatory. The si gnals will be received in the station, and then the information will be converted into data that can be used in the database. The satellites will scan the conservatory and then relay images and pictures to the station to facilitate in the management. This will be achieved through the use of NASA Tera satellites which provide refined global pictures to give a clear view of the land patterns and distribution of ecosystems. They help in providing the best quality land cover maps which enables the policy makers and scientists in charge of natural resources do researches well and monitor objects effectively (Przyborski, 2011). NASA Tera satellites provide more detailed and clear pictures of a place based on digital database of images. They also use MODIS sensor’s vintage, which facilitates collection, of high quality data and also merging of multiple looks into a single image. The MODIS land cover maps have different cover types which includes natural vegetations like wetlands, sa vannas, evergreen forests and deciduous. The cost of NASA Tera satellites is estimated to be $ 424,000. It will be extremely effective in monitoring the movement of the endangered within the conservatory. The satellites provide refined pictures and, therefore, the personnel in charge of the ecosystem will monitor the wildlife successfully (Przyborski, 2011). Data acquisition Ensuring that the required peripheral or hardware is available will
