Research ArticleOpen accessIn the abstractSuitability of Using Phragmites australis and Tamarix aphylla as Vegetation Filters in Industrial AreasWafa’a A. Al-TaisanProblem Statement: Many soils of different areas of the world are subjected to heavy metal pollution due to human activities especially the industry. These metals are hazardous to human health and could affect ecosystems. Toxic metal pollution in water and soil is a major environmental problem and most conventional remediation approaches do not provide acceptable solution, hence the studies of … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 8,450 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessment of Pulverised Fly Ash (PFA) as an Ameliorant of Lead Contaminated SoilsEdmond Gatima, Mwinyikione Mwinyihija, Ken KillhamFly Ash (FA) is obtained by electrostatic or mechanical precipitation of dust-like particles from the flue gases of furnace fired with coal or lignite at 1100 to 1400°C. About 95-99% of Fly Ash consists of oxides of Si, Al, Fe and Ca, about 0.5 to 3.5% consists of Na, P, K and S and the remainder is composed of trace … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,017 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Inverse Kinematics of the Plane System 2-3 in a Mechatronic MP2R System, by a Trigonometric MethodRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.Robots have penetrated today in almost all industrial fields, being much more precise than humans in the execution of operations, but also faster, more dynamic, more stable and more resilient, working 24 h of the 24 h possible, in any season, breaks, holidays, vacations and especially without getting sick. The most important fact is that they can also perform special … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 20 Dec 2017 · 7,813 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Some Heavy Metals in Some Morpho-Physiological Parameters in Maize SeedlingsSali Aliu, Bekim Gashi, Imer Rusinovci et al.Nowadays the heavy-metal pollution of the soil is causing ever greater problems, exacerbated by the fact that the heavy metals accumulated in plants may, either directly or indirectly, find their way into animals and human beings. Maize is one of the world’s most important crops, ranking third after wheat and rice, so the changes induced by one of the most … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 8,432 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAluminium Chloride Exposure Had No Effects on the Epididymis of Wistar RatsSamuel Adeniyi Ojo, Joseph Olajide Hambolu, Sunday Samuel Adebisi, Adebayo Adekunle BuraimohAluminium is a ubiquitous element and one of the trace elements with moderate toxic effect on living organism. It is generally a recognized neurotoxin that is believed to be at the root cause of Alzheimer’s disease and third most abundant element in the earth’s crust after oxygen and silicon. Traditionally, aluminium has been considered as nontoxic to humans. However, in … …Current Research in Medicine, Vol. 3, Issue 2 · 25 Aug 2012 · 7,455 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNew Role of Sulfuric Acid In Production of Multicomponent Fertilizers From Renewable SourcesHelena Górecka, Henryk Górecki, Katarzyna Chojnacka et al.The paper discusses the possibility of using renewable sources: slaughter wastes and wood ashes in the production of NPK fertilizers. The content of macronutrients, micronutrients and toxic elements in these materials was reported. In the present work, poultry feathers were used as fertilizer source of nitrogen, animal bones as the source of phosphorus and wood ash as the source of … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 8,378 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDynamic Elements at MP3RRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.Mechatronic robotic systems are today widely used worldwide to ease human work, but especially where work is dangerous, in toxic, radioactive, chemical, explosive atmospheres, without air such as underwater or in the cosmos, or in places hard to reach the man. Robots can take the tedious repetitive work under any circumstances and they can perform a difficult operation for a … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 23 Nov 2017 · 7,573 accessesView PDF Cite
