Research ArticleOpen accessIn the abstractNeural Network Change Detection Model for Satellite Images Using Textural and Spectral CharacteristicsA. K. Helmy, Gh. S. El-TaweelProblem statement: Change detection is the process of identifying difference of the state of an object or phenomena by observing it at different time. Essentially, it involves the ability to quantify temporal effects using multi-temporal data sets. Information about change is necessary for evaluating land cover and the management of natural resources. Approach: A neural network model based on both … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 8,162 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrengthening Conservation in the Tropics: The Water Canon of Costa RicaFrancisco Benavides, John N. VeenstraProblem statement: The tropics contain primary forests with a significant value for society, as they provide services such as carbon sequestration, soil conservation, bio-prospecting, water storage and others. Competing land uses have not favored conservation during the last several decades and therefore the need for an effective public policy instrument to curtail forest loss is evident. Approach: This article analyzed … …American Journal of Environmental Sciences, Vol. 5, Issue 2 · 30 Apr 2009 · 6,914 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelational GIS and Remote Sensing Database System for Al-Salt Area, JordanEyad H.R. Fadda, Maher Kakish, Emad Jalal AkawwiDue to the importance of database systems, integration between two Geomatics sciences, GIS and Remote Sensing has been made in order to support and serve various sectors in Jordan. GIS has been used to create layers that can show decision makers in a simple, easy and flexible manner. Remote Sensing will be used in creating images of how Jordan is … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 6,957 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Development of a Photovoltaic Power System for Tropical Greenhouse CoolingFaisal Mohammed Seif Al-Shamiry, Desa Ahmad, Abdul Rashid Mohamed Sharif et al.Renewable energy sources like photovoltaic (PV) panels are used today in many applications. Natural ventilation in tropical greenhouse is common method for ventilation, which gives higher inside temperatures compared to the outside temperatures. In addition, this type of ventilation is not enough to reduce high temperature inside the structure in low land areas. Thus the requirement of cooling is increased. … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 8,216 accessesView PDFCite
Research ArticleOpen accessIn the abstractFloodplain Plant Diversity and Anthropogenic Impacts in the Irtysh River Valley, Northeastern KazakhstanShynar Zhanybekovna Arynova, Kanat Kombarovich Akhmetov, Galymbek Sovetovich Azhayev et al.This study investigates the composition, diversity, and ecological adaptation strategies of plant communities in the Irtysh River floodplain (Northeastern Kazakhstan) under natural and anthropogenic pressures. Field-based geobotanical surveys were conducted from May to August 2024 across 40 representative plots. Standard phytocoenotic description methods were employed, along with phenological and ecological assessments. A total of 549 vascular plant species from 74 … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 26 Nov 2025 · 1,934 accessesView PDFCite
Research ArticleOpen accessIn the abstractClimate Change Adaptation in Acid Sulfate LandscapesChuxia LinOxidation of sulfide minerals produces sulfuric acid and consequently creates Acid Sulfate Landscapes (ASLs), which represent one of the most degraded types of land-surface environments. Although acid sulfate-producing weathering is a naturally occurring process, it is markedly facilitated by human intervention. Mining is by far the dominant anthropogenic cause for the creation of inland acid sulfate footprints while land reclamation … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 7 Jul 2012 · 7,387 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Vegetation Dynamics using Long-Term Normalized Difference Vegetation Index Time-SeriesTamara Bellone, Piero Boccardo, Francesca PerezProblem statement: The Normalized Difference Vegetation Index (NDVI) is the most extensively used satellite-derived index of vegetation health and density. Since climate is one of the most important factors affecting vegetation condition, satellite-derived vegetation indexes have been often used to evaluate climatic and environmental changes at regional and global scale. The proposed study attempted to investigate the temporal vegetation dynamics … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,406 accessesView PDFCite
Research ArticleOpen accessIn the abstractSea Level Threat in TuvaluThan Aung, Awnesh Singh, Uma PrasadProblem statement: Recently the impacts of climate change, in particular, sea level rise, had been a major concern for many Pacific island countries. In early 2000, there were a series of media coverage over sea level rise issues using Tuvalu as an example. The daily life of Tuvalu revolves around the ocean and the immediate threat on the islands people, … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 13,956 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Review of Effects of Environmental Change on Human HealthUttam PaudelCurrent knowledge production on the effects of environmental exposures on human health reflects technological, social and economic development broadly; theoretical and methodological advancements in social science and medicine more specifically. Human health and the welfare mainly rely on refurbishing and protecting the integrity of the natural systems such as fresh air, safe water, biodiversity, toxic waste management and proper land … …American Journal of Environmental Sciences, Vol. 14, Issue 3 · 29 Apr 2018 · 8,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractINTEREST COVERAGE RATIOS (ICRs) AND FINANCIAL SUSTAINABILITY: APPLICATION TO FIRMS WITH BOVINE DAIRY LIVESTOCKGiuseppe Bonazzi, Mattia IottiAgricultural firms with bovine dairy livestock are characterized by high investments in capital equipment and this is determined by the biological cycle of production, which requires large investments in land, facilities and bovine herd. These large investments require funding from equity capital or debt capital, which generates financial costs. Therefore, it is necessary to assess not only the profitability of … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 4 · 15 Oct 2014 · 7,657 accessesView PDFCite
