Remote sensing data play an important role in environmental planning and monitoring. The current study aimed to investigate the land surface temperature (LST) and the effect of environmental factors on the LST, to identify the temporal-spatial patterns and determine the hot spots in the period of 2013 to 2019, using Landsat 8 images. The effect of spectral indices: Normalized Difference Build-u...
Abstract Land use change has detrimental impacts on the planet. It is not only a major cause of biodiversity loss, through habitat destruction and fragmentation, but also an important driver for climate change, deforestation peat oxidation. mainly driven by food production, which meat production comprises share. Ecomodernists therefore feel reduction impact paramount sustainable future. To achi...
proceeds, some species may be driven to extinction only Loss of habitat due to human activities is a major threat to reestablish in the community following more extensive to biological diversity (Ehrlich and Ehrlich 1981; Wilson habitat destruction that drives more competitive species 1988). Recent models of competition among sessile orto extinction. Thus, the models of Tilman et al. (1994, gan...
On several occasions, winter freezes have wrought severe destruction on Florida agriculture. A series of devastating freezes around the turn of the twentieth century, and again during the 1980s, were related to anomalies in the large-scale flow of the ocean–atmosphere system. During the twentieth century, substantial areas of wetlands in south Florida were drained and converted to agricultural ...
a group of palestinians became refugees in neighboring arab countries after their homeland was occupied by israel. other part of the population continued to reside in the occupied country at karate gerbil and ghazi, but they have lost the peace, and the political stability and establishment. consequently, this disordered situation affected palestinian poetry.refugee status, exile, massacre, pil...
Due to physiography and weak structure, the pasture soils in Boroojen are potentially degradable. Converting pastures to agricultural land accelerates the degradation processes. A study was conducted in 1999 to show the effects of almost 20 years of farming on originally pasture land on soil physical properties, fertility, and tilth index of pastures in Boroojen region in Chahar Mahal and Bakht...
Irregular and unstable urban development has increased marginalization, destruction of urban green areas and increased demand for urban land, which in itself has led to the disappearance of urban green spaces and land use change of such lands and is possible. Cause certain global environmental problems such as the formation of urban heat islands, because urban green space is one of the importan...
New Zealand has a legal 3D cadastre, and has done since the inception of its cadastral survey and tenure systems around 150 years ago. However, the digital representation of the cadastre is 2D with 3D situations handled via static plan, section and elevation images and supporting textual information. Work is currently underway to develop a 3D digital cadastre that will enable the 3D spatial ext...
The detection of materials or devices for nuclear or radiological weapons of mass destruction is fundamentally important to national safety and security, and detection technologies are necessary both to nd and to verify the location of those materials or devices. To ful ll this task, this paper presents a statistical approach to the detection and location of radioactive target via wireless sen...
One of the principal concerns in graduate admissions is how future performance in graduate studies may be predicted from a candidate’s undergraduate achievements. In this study, we examined the statistical relationship between B.Sc. and M.Sc. achievements using a dataset that is not subject to an admission-induced selection bias. Our analysis yielded three insights. First, we were able to expla...
