Research ArticleOpen accessIn the abstractWater Quality Assessment of A Constructed Wetland Treating Landfill Leachate and Industrial Park RunoffC. Galbrand, I. G. Lemieux, A. E. Ghaly et al.A surface flow constructed wetland was used for the treatment of landfill leachate and industrial park runoff. The wetland consisted of seven cells and was designed as a kidney shape to facilitate high retention time. The water quality was assessed for iron, manganese, phosphorus (orthophosphate), pH, dissolved oxygen (DO), nitrogen (ammonia, nitrate, nitrite and TKN), chemical oxygen demand (COD), total … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 7,368 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBioaccumulation of Cr(III) ions by Blue-Green alga Spirulina sp. Part I. A Comparison with BiosorptionKatarzyna ChojnackaThe paper presents the results of studies on kinetics and equilibrium of bioaccumulation process of Cr(III) ions by blue-green alga Spirulina sp. Bioaccumulation was described as the process that consists of two stages, passive (identical with biosorption) and active (accumulation inside the cells). The passive stage (similarly as biosorption itself) was found to be quick process and the subsequent active … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,702 accessesView PDF Cite

Research ArticleOpen accessIn the abstractWettability and Interfacial Tension Alteration of Rare-Earth Doped Yttrium Iron Garnet under Influence of Electromagnetic WavesLau Zhen Yin, Lee Kean Chuan, Beh Hoe Guan et al.Yttrium Iron Garnet (YIG) doped with rare-earth elements have shown to alter the magnetic properties of garnet nanoparticles (NPs), which is believed to have direct influence on the wettability, interfacial tension and viscosity alteration of garnet nanofluids. In this study, Y2.8R0.2Fe5O12 (R = Lanthanum (La), Neodymium (Nd) and Samarium (Sm)) NPs were synthesized by using the sol gel auto-combustion method … …American Journal of Applied Sciences, Vol. 16, Issue 6 · 25 Jul 2019 · 7,684 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSolid Waste Disposal and its Impact on Surrounding Environment of Matuail landfill Site, Dhaka, BangladeshMd. Faruque Hossain, Esrat Jahan, Zakia Parveen et al.An investigation was conducted to assess the impact of solid waste disposal on surrounding environment of Matuail landfill site of Dhaka city. Three different locations such as current dumping, abandoned and its surrounded agricultural areas of Matuail landfill were selected for soil and plant samples, leachate from active dumping and fish samples from treated leachate pond. The Cu, Zn and … …American Journal of Environmental Sciences, Vol. 14, Issue 5 · 16 Nov 2018 · 12,695 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBacteria of the Clostridium Genus, Methane and Hydrogen Sulfide in Sulfide Mud of the Taman Peninsula ReservoirsYury Aleksandrovich Fedorov, Gar'kusha Dmitry Nikolayevich, Roman Gennad'yevich TrubnikThe features of the distribution of the concentrations of hydrogen sulfide, methane and the number of sulfite-reducing clostridia in the mud of the Bugazsky, Kiziltashsky and Vityazevsky limans and Chembursky lake were studied, and their physiological and chemical conditions and levels of anthropogenic loading were assessed. The tendency of reduction of the content of the studied reduced gases from the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 28 Aug 2018 · 7,087 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIsolation and Identification of Oral Cancer Stem Cells (CSC) within Commercially Available Cell LinesRobert Chauncey, Kai Hatch, Toni Jilka et al.Previous studies have demonstrated some tumors develop or maintain a small sub-population of cells with stem cell-like properties. This Cancer Stem Cells (CSC) may exhibit differential properties that allow their escape from traditional radiation or chemotherapy treatments and may therefore be responsible for cancer recurrence. Few studies have explored this phenomenon among oral cancer cell lines, therefore the objective of … …Current Research in Dentistry, Vol. 9, Issue 1 · 2 Jun 2018 · 12,719 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBurn Wound Healing Effect and Hair Growth Promoting Activity of Lawsonia inermis L. and Honey in Oryctolagus cuniculus RabbitsZouhir Djerrou, Imane Mokhbi, Khadidja Saci Hadef et al.This study aimed to assess Lawsonia inermis L. and honey mixture effects on burn wounds and hair growth in rabbits. Nine male Oryctolagus cuniculus local rabbits were allocated randomly in 3 groups. After antisepsis and local anesthesia, four circular burns were created on the animal’s backs. Immediately after burning, the wounds were covered with honey in three rabbits (HON group), … …OnLine Journal of Biological Sciences, Vol. 16, Issue 2 · 23 Apr 2016 · 7,812 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRemediation of Feedlot Nutrients Runoff by Electrocoagulation ProcessArjun Thapa, Shafiqur Rahman, Md. Saidul BorhanNutrient runoff from Concentrated Animal Feeding Operations (CAFOs) may cause ground and surface water pollution. Scientists and researchers are continually searching for appropriate technologies to mitigate feedlot nutrient runoff pollution. In this study, suitability of electrocoagulation treatment process was examined under laboratory conditions to mitigate nutrient pollutants from the feedlot runoff. Feedlot runoff was treated with three different type of … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 9 Nov 2015 · 7,080 accessesView PDF Cite

Research ArticleOpen accessIn the abstractANTIBACTERIAL ACTIVITY EVALUATION OF 15 EUCALYPTUS SPECIES ESSENTIAL OILS AGAINST CLINICALLY RELEVANT PATHOGENIC BACTERIADias C., V. Pereira, M.C.B.M. De Vasconcelos et al.This study aims to evaluate the potential of 15 Eucalyptus species essential oils as alternatives to clinical surface disinfectants with known association to antibiotic resistance. Four reference pathogenic bacteria were tested: Pseudomonas aeruginosa (ATCC10145), Escherichia coli (CECT434), Staphylococcus aureus (CECT976) and Listeria monocytogenes (ATCC15313). Gram-positive bacteria revealed higher sensitivity than Gram-negative.

Research ArticleOpen accessIn the abstractTHE IMPACT OF THE POLYMER COATING NUTRISPHERE™ IN INCREASING NITROGEN USE EFFICIENCY AND CORN YIELDTimothy A. Smith, Ronnie W. Heiniger, Pawel WiatrakCurrently, it is estimated that 50 to 60% of the N applied fertilizer is actually utilized by the crop with the remaining N lost through leaching or denitrification. A three year study was conducted at eight locations in North Carolina to examine the impact of Nutrisphere™ on corn yield, optimum N rate, maximum yield, tissue N concentration, plant biomass and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 21 Dec 2013 · 8,037 accessesView PDF Cite
