Research ArticleOpen accessIn the keywordsMonstrous Hazards Produced by High Radioactivity Levels Around Assiut Thermal Power PlantHany El-Gamal, Mohamed El-Azab Farid, Abdulla Ibrahim Abdel Mageed et al.The natural radioactivity level of heavy oil, ash and soil samples around Assiut Thermal Power Plant (ATPP) in Egypt was determined using gamma ray spectrometry. The average concentrations of 226Ra, 232Th and 40K in fly ash were found to be 2307±143, 1281±80 and 1218±129 Bq kg-1, respectively, while the corresponding values in soil samples were 2670±107, 1401±78 and 1495±100 Bq … …American Journal of Environmental Sciences, Vol. 9, Issue 5 · 17 Sep 2013 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDelftia Acidovorans Bacteremia in an Intravenous Drug AbuserRocco J. Perla, Eric L. KnutsonDelftia acidovorans (Comamonas acidovorans) is an aerobic, non-fastidious, non-fermentative gram-negative bacillus classified in the Pseudomonas rRNA homology group III that is generally regarded as an environmental organism found in soil and water and as a non-pathogen. We report the first case of systemic D. acidovorans infection in a patient without a long-term immunosuppressive condition where D. acidovorans has been recovered … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 7,307 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractWastewater Treatment Using Organic By-Products from Agroindustry: A Case Study in the District of Valera, Amazonas Region, Northern PeruEli Morales-Rojas, Sayda Karina García Caro et al.This research evaluates the use of two types of coagulants based on organic by-products (orange and passion fruit) in wastewater (RA) treatment. The system was composed of glass tanks installed in parallel. The coagulants were elaborated and applied in aqueous solution and in powder form, and 7 physicochemical and microbiological parameters were also analyzed.
