Research ArticleOpen accessIn the abstractEnergy Flow in Agriculture: BangladeshM. S. Alam, M. R. Alam, K. K. IslamIn this paper, a qualitative energy flow analysis in Bangladesh agriculture has been made for a period from 1980-81 to 2000-01 to evaluate the impact of energy input to produce output. Human and animal muscle power and machinery energy for tillage operation, electricity and diesel energy for irrigation, fertilizer and pesticides energy for growth and protection are taken into account. … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 11,592 accessesView PDFCite
Research ArticleOpen accessIn the abstractWind Speed Simulation Using WaveletsA. H. Siddiqi, S. Khan, S. RehmanMost of the renewable energy sources have direct or indirect link with the sun. Wind is also a form of solar energy. It is initiated by uneven heating of the atmospheric air by the sun, affected from the topography and surface roughness of the earth's surface and rotation of the earth. The earth's terrain, water surfaces and vegetation cover modifies … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomated Fall Armyworm (Spodoptera frugiperda, J.E. Smith) Pheromone Trap Based on Machine LearningSimon H. Chiwamba, Jackson Phiri, Philip O.Y. Nkunika et al.Maize is the main food crop that meets the nutritional needs of both humans and livestock in the sub-Saharan African region. Maize crop has in the recent past been threatened by the fall armyworm (Spodoptera frugiperda, J.E Smith) which has caused considerable maize yield losses in the region. Controlling this pest requires knowledge on the time, location and extent of … …Journal of Computer Science, Vol. 15, Issue 12 · 19 Dec 2019 · 8,369 accessesView PDFCite
EditorialOpen accessIn the abstractProblems of Ultra-High Energy Cosmic RaysAnna V. UrysonCosmic rays are energetic particles coming to the Earth from space. They bombard the atmosphere producing cascades of particles that spread over a large area when they reach the ground. Cosmic ray energies vary in the wide band from about 108 eV up to few 1020 eV. It is established that most particles with energies of ~ (108-109) eV come … …Space Science International, Vol. 2, Issue 1 · 6 Dec 2014 · 13,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Near Real-time Early Warning System on Erosion HazardsFaisal H. Ali, Tew K. HuiWith many incidences of landslides, mudslides and erosion occurrences lately, especially in the highlands in Malaysia, properties were damaged and lives were lost. Seeing the need of resolving and minimizing such untoward incidences, a study has been embarked on developing a near real-time early warning system on erosion hazards so as to provide an early warning to the public, whenever … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 6,710 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCuInSe2 (CIS) as A light Absorption Layer of Photovoltaic Solar-CellsOmar Abdulsada AliArrested precipitation methode used to synthesize CuInSe2 (CIS) nanocrystals were added to a hot solvent with organic capping ligands to control nanocrystal formation and growth. CIS thin films deposited onto Soda-Lima Glass (SLG) substrate by spray-coat, then selenized in Ar-atmosphere to form CIS thin films. PVs were made with power conversion efficiencies of 0.631% as-deposited and 0.846% after selenization, for … …Current Research in Nanotechnology, Vol. 7, Issue 1 · 29 Feb 2016 · 14,791 accessesView PDFCite
