Research ArticleOpen accessPhrase in the titleAdsorption and Descaling of Cellucotton and Chitosan-Modified Bentonite for Produced WaterTao Yu, Ying Wang, Chengtun Qu et al.The compatibility of non-identical layers within the water present in the produced oil is poor and ion reactions in the oil mixed with water result in scale formation, thereby having a significant impact on oilfield safety production. In this study, methods for the descaling of produced water from different blocks were studied according to the quality characteristics of the produced … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 18 May 2020 · 6,664 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleBioremediation of Petroleum Hydrocarbon-Polluted Mangrove Swamps Using Nutrient Formula Produced From Water Hyacint (Eicchornia crassipes)Frank Anayo Orji, Abiye Anthony Ibiene, Phillip O. OkerentugbaLaboratory-scale studies were carried out using a nutrient formula produced from Eicchornia crassipes plant to achieve bioremediation of crude oil impacted mangrove soil. In a 70 day study, the culturable heterotrophic bacterial population of the Eichhornia crassipes recipe increased from 6.26×105 Cfu/g to 2.69×107 Cfu/g. The control set-up had its total culturable bacterial count increased from 5.76×105 Cfu/g to 1.24×106 … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,643 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsMechanical Strength and Durability Properties of High Performance Mortar Containing Densified Silica FumeCheah Chee Ban, Mahyuddin RamliProblem statement: Numerous data and information on pozzolanic reaction and microfiller properties of silica fume were derived from laboratory investigation on silica fume in undensified form. Currently, due to low bulk density of undensified silica fume which poses problem in transportation and handling of the material, silica fume are commercially supplied in densified form. Densification process used to increase bulk … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,956 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCharacterization of Pseudomonas aeruginosa Infecting Bacteriophages from Swiftlet House Pond Water and Sewage in South Kalimantan, IndonesiaSiti Gusti Ningrum, Dyah Widhowati, Titin Yulinery et al.Pseudomonas aeruginosa is an opportunistic bacterium that may occur in animal-production environments and contribute to microbial contamination of animal-derived products. However, information on P. aeruginosa-infecting bacteriophages in artificial swiftlet-house environments remains limited. This study aimed to isolate and evaluate P. aeruginosa-infecting bacteriophages from the swiftlet-house environment in South Kalimantan, Indonesia. A total of 75 samples involving pond waters (n = … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 26 Oct 2026 · 55 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMechanical Scarification and Sucrose Priming Overcome Physical Dormancy in Caesalpinia spinosa (Tara) Seeds from the Peruvian HighlandsWilfredo Ruiz-Camacho, Ítalo Maldonado Ramirez, Juan Eduardo Suarez Rivadeneira et al.Caesalpinia spinose (tara) is a leguminous tree native to the Peruvian Andes-Amazon region, valued for soil restoration and high tannin content. However, its large-scale propagation is constrained by physical seed dormancy caused by a hard and impermeable seed coat. This study evaluated six pre-germination treatments to break dormancy and enhance early seedling development under local agroclimatic conditions in Magdalena District, … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 12 Aug 2026 · 1,204 accessesView PDF Cite
