Research ArticleOpen accessIn the keywordsSPATIAL AND MULTIVARIATE ANALYSIS OF TRACE ELEMENTS IN THE SURFACE WATER AND DEEP SEDIMENTS OF FRESH WATER AQUATIC ECOSYSTEMKantha Deivi Arunachalam, Sathesh Kumar Annamalai, Kamesh Viswanathan Baskaran et al.The aim of this study was to assess the levels of various trace metals present in water and sediment of fresh water aquatic ecosystem during the post monsoon season. The study was extended to identify the trace metal contamination in the water and sediment samples collected along the shores of Lambapur and Peddagattu the tribal villages in India using an … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 26 Mar 2014 · 7,597 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparability Assessment of Polycyclic Aromatic Hydrocarbons Tissue Load in Some Fish: Implication on Reciprocal Synergism and Risk AssessmentVictor Eshu Okpashi, Ogugua Victor Nwadiogbu, Joshua Parkar Elijah et al.Six years after oil spill occur in Qua Ibeo river, environmental monitoring was set out to investigate residual petroleum compounds (PHCs) that are bio-accumulated by fish. Bio-concentration of residual Polycyclic Aromatic Hydrocarbons (PAHs) in fish tissues was determined in six fresh fish species. Twelve water samples were collected from Qua Ibeo river 1 KM apart. The screening was conducted using … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Apr 2017 · 7,541 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTHE ADVERSE EFFECT OF STEEL PARTICLE CONTAMINANTS ON FATIGUE LIFE OF GREASE LUBRICATED BALL BEARINGSA. Stathis, Th. Costopoulos, D. Koulocheris, K. RaptisThe rating life of ball bearings is reduced when hard particle contaminants are present in the lubricant. Usually, this life reduction is taken into account in the calculation of modified rating life by using the contamination factor through a general characterization of the lubrication conditions. However, the impact of contaminant’s variables such as size, hardness and concentration level has to … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 14 Jul 2014 · 6,991 accessesView PDF Cite

Research ArticleOpen accessIn the abstractVariability of Hydraulic Conductivity Due to Multiple FactorsSanjit K. Deb, Manoj K. ShuklaSoil properties are greatly influenced by intrinsic factors of soil formation as well as extrinsic factors associated with land use and management and vary both in time and space. Intrinsic variability is caused by the pedogenesis and usually takes place at large time scales. The variability caused by extrinsic factors could take effect relatively quickly and could not be treated … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 13 Aug 2012 · 10,219 accessesView PDF Cite
