Research ArticleOpen accessEvery word in the titleOptimal Production Planning of Electricity from Coal-Fired Power Plant Networks under Environmental ConsiderationsHabib H. Al-Ali, Yousef Saif, Ali Elkamel, Ali LohiIn this study, electricity production from a network of coal power plants and under environmental constraints is considered. Several pollutants are incorporated into the decision planning process including nitrogen oxides (NOx), sulfur oxides (SOx) and mercury (Hg). A Nonconvex Mixed Integer Nonlinear Programming (MINLP) model was first developed to assist in the evaluation process. An exact linearization of the nonconvex … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Mar 2008 · 7,070 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTHE BLENDING EFFECT OF COALITE, COCONUT SHELL CHARCOAL AND GELAM WOOD CHARCOAL ON CALORIFIC VALUENukman, Riman Sipahutar, Irsyadi Yani, Taufik AriefThe aim of this research is to scrutinize the effect of blend solid fuels consisting of coalite, coconut shell charcoal and gelam wood charcoal on calorific value. Coalite is the solid fuels made from coal that is mined from the earth, while coconuts shell charcoal and gelam wood charcoal are processed from natural plants. Coalite, coconut shell charcoal and gelam … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 3 Mar 2014 · 7,564 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRationalizing Resource Utilization in Cloud Computing Using Coalition Formation StrategyHend Fakhri Noureldin, Mai FadelEven though the contribution of cloud computing towards the Sustainable Development (SD) of communities is still under research investigation, cloud computing has become an integral part of many ICT solutions that shape our daily lives. Thus, some researchers recommend taking considerable actions to point cloud computing development towards supporting SD. In this research, an approach to designing energy efficient cloud … …Journal of Computer Science, Vol. 17, Issue 6 · 15 Jun 2021 · 6,978 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePollution Characteristics and Sources Analysis of Soil Heavy Metal in Taoyuan Coal Mine of Suzhou CityHaimin SuSoil is one of the most important resources and an important part of ecosystem in the development of human survival. The purposes of this study are to investigate concentration characteristics and sources analysis of heavy metals in Taoyuan coal mine of Suzhou City. 30 soil samples were collected and characterized for metal concentration (Cd, Cr, Cu, Pb, Zn and As), … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 29 Jan 2022 · 5,914 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnvironmental Risk Assessment of Coal-Ash-Amended Soil Based on Continuous Planting of PakchoiWenxuan Sun, Liyong Bai, Huihui Ji et al.The agricultural application of coal ash which contains a variety of chemical nutrients may also cause heavy metal pollution of crops and soil. In this study, pakchoi was cultivated for four consecutive seasons in pots of brown soil amended with fly ash or bottom ash. With subsequent plantings, the total concentrations in the four fractions of Pb, Cr and Cu … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 11 May 2021 · 6,862 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Application of Standard Operating Procedure and Work Motivation to Occupational Accident on Coal Mine EmployeesAprizal Satria Hanafi, Qomariyatus SholihahMining industry is one of the most high risk jobs, thus requiring the application of standard operating procedure in every phase of the work. Based on the preliminary study at PT. Darma Henwa, Site Asam-Asam Coal Project there were 126 cases of occupational accidents in 2012 and 22 cases of occupational accidents in 2013. Several studies have shown, do not … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 25 Jan 2017 · 8,169 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReducing Ammonia Loss from Urea by Mixing with Humic and Fulvic Acids Isolated from CoalAmeera Abdul Reeza, Osumanu Haruna Ahmed, Nik Muhamad Nik Ab. Majid, Mohamadu Boyie JallohProblem statement: Ammonia volatilization is a major pathway for nitrogen loss from surface applied urea. While all top-dressed ammonia and ammonium based N fertilizers can volatilize, the potential loss is greatest with urea and fluids containing urea. As much as 20-50% of N applied to soils is lost through volatilization alone. Thus, the objective of this laboratory study was to … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 10,897 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHard Coal Fly Ash and Silica-Effect of Fine Particulate Matter Deposits on Brassica chinensisChristian Ulrichs, Uwe Schmidt, Tanja Mucha-Pelzer et al.Problem statement: One focus in recent atmospheric pollution research is on fine Particle Matter (PM), especially as result of increasing traffic and anthropogenic activity in urban areas. Here, the impact on animal and human health has been in the center of many studies. Despite the fact that PM depositions can affect plants on the long term, there are only few … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,648 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIntegrating Renewable and Nonrenewable Energies in Power Plant PlanningHabib H. Al-Ali, Yousef Saif, Ali Elkamel, Ali LohiProblem statement: Electricity can be generated from different type of technologies such as fossil and non-fossil power plants. Among these technologies, coal-fired power plants have been a major route for electricity generation. Recently, environmental constraints were imposed over the coal power plant operations in order to reduce their emissions. Besides, renewable energy power plants such as hydroelectric, wind, solar and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractFormation of Vegetation Cover and Soil Quality Indicators at the Mine Sites of a Gold-Bearing Deposit (the Case of Kara-Agash, Kazakhstan)Vadim Chashkov, Aliya Bugubaeva et al.At present, the processes of natural recovery, vegetation coverage, and degraded lands of several coal, iron ore, uranium, and polymetallic mines and gold-bearing deposits are well-studied. The present study aims to identify opportunities to shape the soil layer and vegetation cover on reclaimed dumps/tailings of industrial waste and degraded land via artificial restoration. For this purpose, in July 2023, studies … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 16 Sep 2024 · 4,765 accessesView PDFCite
