Research ArticleOpen accessIn the abstractSimulation of Production of Anhydrous Bioethanol using Glycerol and 1-Butyl-3-Methylimidazolyl-Tetrafluoroborate in the Aspen Plus SimulatorJosé Izaquiel Santos da Silva, Lílian da Silva Félix, Mariana Martins Vieira et al.Biofuels are present in the global scenario as an energy source derived from organic biomass, representing an economic and environmental alternative. They are a renewable source of energy with low rates of pollutants emissions and, consequently, less carbon dioxide is released into the atmosphere. The obtaining of bioethanol is originated from a fermentation process, in which a multi-component mix is … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 16 Jun 2021 · 7,114 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial-Dynamics of Trace Metals Accumulation and Physicochemical Characteristics in Ikpukulu-Ama Creeks, Rivers State, NigeriaDavies Ibienebo Chris, Khang Wen Goh, Davies Imachrist Ibienebo et al.The study examines the spatial-dynamics variability of water parameters and trace metal concentrations between January and June 2023 at the Ikpukulu-Ama sites of the Bonny River, Nigeria. Key parameters analyzed include temperature, salinity, pH, transparency, dissolved oxygen, and trace metals (Ni, Pb, Cd, Cu, Zn) across three sites. The highest temperature, 32.56°C, was recorded at Site 2, indicating potential thermal … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 29 Jul 2026 · 499 accessesView PDFCite
EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,527 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Water-Soluble Polymers for Extraction Separation of Amino Acids of Various StructuresNadezhda Yakovlevna Mokshina, Dmitry Vladimirovich Bykovskiy, Gennadiy Valentinovich Shatalov, Oksana Anatolievna PakhomovaThis article actualizes the task of developing new methods for extraction separation of amino acids for the analysis and purification of target components in the production of food supplements, pharmaceuticals, agricultural products and cosmetics; it also presents the extraction separation results for binary mixtures of histidine, proline and methionine using water-soluble homo- and co-polimers with various molecular weight values. We … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 10 Dec 2015 · 6,646 accessesView PDFCite
Research ArticleOpen accessIn the abstractMANGANESE SPECIATION IN SELECTED AGRICULTURAL SOILS OF PENINSULAR MALAYSIAJ. Habibah, J. Khairiah, B.S. Ismail, M.D. KadderiManganese speciation in selected agricultural soils of Peninsular Malaysia is discussed in this study. Manganese concentration in the Easily Leacheable and Ion Exchangeable (ELFE), Acid Reducible (AR), Organic Oxidizable (OO) and Resistant (RR) fractions of soils developed on weathered rocks, soils of mixed nature, alluvium and peat deposits are described. The total manganese concentration in soils developed on weathered rocks … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 7 Apr 2014 · 7,497 accessesView PDFCite
Research ArticleOpen accessIn the abstractNATURAL ANTIOXIDANT INGREDIENT FROM BY-PRODUCTS OF FRUITSG. S. El-Baroty, M. F. Khalil, S. H.A. MostafaThe contents of total phenolics compounds and their phenolic constituents were quantified in organic and aqueous of four varieties (Zebdia, Sukkari, taimor and Hindi) of mango (Mangifera indica L.), seeds pulp and kernel, one varieties of pomegranate (Punica ranatum L., peel) and peanut (Arachis hypogaea L., Giza 6, shell) by-products. The antioxidant activities of all by products extracts were assessed … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 22 Mar 2014 · 8,173 accessesView PDFCite
Research ArticleOpen accessIn the abstractBONE MEAL AS ALTERNATIVE TREATMENT FOR ACIDIC AND METAL CONTAMINATED ACID MINE DRAINAGE WATER EFFLUENT: LAB SCALECarolyn Payus, Olga David, Moh Pak YanThe typical methods of treatment for acidic and metal contaminated water effluent such as the Acid Mine Drainage (AMD) will always focus on either civil engineering methods, such as disposal, excavation, drainage and encapsulation or process based technologies such as effluent washing and treatment. These techniques are not environmental friendly, costly and unsustainable, thus environmental damaging. Nowadays, there is a … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 3 Mar 2014 · 7,981 accessesView PDFCite
