Research ArticleOpen accessIn the keywordsBroodstock Formation and Sterlet (Acipenser ruthenus) Reproduction in the West-Kazakhstan RegionGuldana Maratkyzy Maratova, Kuanysh Isbekov, Shokhan Alpeisov et al.A dramatic decline of sturgeons’ stocks including the sterlet (Acipenser ruthenus) in the Caspian Sea including creates the need to establish aquaculture broodstock. Broodstock management can allow conserving the gene pool of the sterlet and the creation of captive broodstock further serve as a source of sterlet fry aimed at restoring natural populations of the sterlet in the Caspian Sea. … …OnLine Journal of Biological Sciences, Vol. 23, Issue 3 · 11 Jul 2023 · 5,321 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Compost Production from Fruit and Vegetable Market Waste: A Case Study in Bagua, Amazonas (Peru)Juan Eduardo Suarez Rivadeneira, Freddy A. Manayay, Wilfredo Ruiz Camacho, Juan Francisco Robles RuizInadequate management of organic solid waste in municipal markets represents a critical environmental challenge in tropical developing regions, where high humidity (>80%) and elevated temperatures (>25°C) accelerate decomposition, generating leachate and greenhouse gas emissions. In Peru, over 50% of municipal waste is organic, yet less than 20% is valorised through composting, highlighting a substantial technological gap. This study evaluated an … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 11 Aug 2026 · 1,262 accessesView PDFCite
Research ArticleOpen accessIn the abstractCircular Economy Modeling for Waste and Energy Management in A Developing Country: The Case of Greater Beirut AreaAbbas El Toufaili, Dario Pozzetto, Elio Padoano et al.Lebanon's energy system depends largely on imported fuels. Lebanon presented its commitment to increase by 30% its share of Renewable Energies (RE) by 2030. GBA lacks an integrated Municipal Solid Waste Management (MSWM) system. The waste composition in the Greater Beirut Area (GBA) is made of 52.2% organic waste which can be exploited for the production of green Hydrogen (H2) … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 22 Nov 2024 · 5,210 accessesView PDFCite

Research ArticleOpen accessIn the abstractSynergistic Effects of Wheat Bran and Inoculants on Fermentation and Nutritional Quality of Soybean Straw SilageLie Yang, Rundong Qin, Jiahuan Liu et al.The efficient valorisation of lignocellulosic biomass from soybean straw into high-quality silage remains a pressing challenge for sustainable livestock production. This study employed a 3×3 factorial design to systematically investigate the interactive effects between wheat bran additions (0%, 10%, 20% of fresh weight) and microbial inoculant regimes (control, Effective Microorganisms, EM+Trichoderma longibrachiatum) on soybean straw silage quality. Two-way ANOVA revealed … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 1 Jul 2026 · 1,109 accessesView PDFCite
Review ArticleOpen accessIn the abstractRRDTool: A Round Robin Database for Network MonitoringManmohan Singh, Sweta Dargada, Hemant Mewada et al.RRDtool is a circular database that stores time series data. RRD tool assumes time-variable data inintervals of a certain length. An interval is named as a step, and specifiedupon creation of an RRD file which cannot be changed afterward. Because datamay not always come at just the right time, RRD tool will automaticallyinterpolate any submitted data. This is done to … …Journal of Computer Science, Vol. 18, Issue 8 · 27 Aug 2022 · 8,350 accessesView PDFCite
