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. Data analysis was performed using a … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 2 Jul 2026 · 1,172 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of the Degree of Soil Salinity and the Bio preparation on Productivity of Maize in the Shaulder Irrigated MassifMaksat Nurbaiuly Poshanov, Shakhislam Uzakbaevich Laiskhanov, Zhassulan Maratovich Smanov et al.During the study on the Shaulder irrigated massif, the soil salinity maps with different degrees of salinity were compiled at the large-scale 1:10000 in the GIS environment. It was found that the area of saline soils increases with depth. In the upper 0-20 cm layer, 29% is salted and in the 50-100 cm layer, up to 44% is salted. The … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 11 Feb 2022 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractStimulating Properties of Biological Preparations on the Bulb Onion in KazakhstanR. Zh. Ukibaev, N. D. Slyamova, G. T. Kartbaeva et al.This article studies the stimulating properties of biological preparations Orgamica S and F used on bulb onions in Kazakhstan. As a result of our study, it has been proven that the best concentration of Orgamica S and F, which significantly increases the leaf area, is a 0.4% aqueous solution. Biological preparations at a concentration of 0.4% increase the ability of … …OnLine Journal of Biological Sciences, Vol. 21, Issue 4 · 17 Dec 2021 · 5,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Dynamics Simulation and Analysis of Crystallization System in PVC Tunnel Drain-Pipe at Different TemperaturesZhongwei Hou, Xuefu Zhang, Yuanjiang ZhouAiming at the problem that carbonate and calcium ions are easy to crystallize and precipitate in the drain-pipes of limestone tunnels and then adsorb on PVC pipes in Western China, a "solid-liquid interface model" for the interaction between PVC materials and ions in aqueous solution is established by using the molecular dynamics simulation software materials studio and the microscopic mechanism … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 9 Mar 2021 · 6,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractCurrent Growth Conditions of Populus Diversifolia Schrenk and Populus Pruinosa Schrenk in the Syr-Darya ValleyPolina Vesselova, Karina Makhmudova et al.In the context of urbanization of territories and the intensification of agriculture, the biological diversity of animals and plants in their habitats is degrading. The purpose of the study is to determine the edaphic factors affecting the growth of Populus diversifolia Schrenk and Populus pruinosa Schrenk, as well as anthropogenic factors affecting their conservation in the Syr-Darya valley (Kazakhstan). For … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 6 Oct 2022 · 5,542 accessesView PDFCite
Review ArticleOpen accessIn the abstractAntimicrobial Resistance Pattern of Pseudomonas aeruginosa from Different Clinical Specimens: Survey ArticleHosniyeh E. Ladadweh, Hiba H. Falana, Jannat M. Ma’ali et al.Pseudomonas aeruginosa (P.A.) is a gram-negative, aerobic rod bacterium that mainly grows in soil and watery environments, infrequently being a part of microflora in healthy individuals. Since P.A. favors the growth in moistened areas, it can colonize in any simple aqueous solution, which in turn raises the risk of contamination and infection in hospital settings. The emergence of drug resistant … …American Journal of Pharmacology and Toxicology, Vol. 16, Issue 1 · 11 Jan 2021 · 8,396 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating the Effects of Landfill in Azad-Shahr City on the Physicochemical Properties of GroundwaterSara Abdollahi, Safieh Javadinejad, Kaveh Ostad-Ali-Askari, Vijay P. SinghLocations near landfills have a lot of potential for contamination of groundwater, because there is a high potential for contamination with emulsion in these areas. In this study, the quality of physic chemical and carbon-organic materials (TOC) of water wells around landfill of Azad-Shahr city was investigated. To accomplish this purpose, sampling of water from seven deep wells around the … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 3 Jun 2019 · 7,925 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of ZnO Nano Rods for the Batch Adsorption of Cr(VI): A Study of Kinetics and IsothermsSushma Kamath, Venu Gopal Vishwakarma Ramanjaneyalu, Susmita KamilaThe present study reports the synthesis of nano Zinc Oxide (ZnO) and its adsorption behaviour. The ZnO obtained by precipitation method were found to be well-defined nano rods arranged like flower. The shape, size and structure of ZnO were characterized from X-Ray Diffraction (XRD), Energy Dispersive X-ray (EDX) and Scanning Electron Microscope (SEM) analysis. These nano rods were utilized for … …American Journal of Applied Sciences, Vol. 16, Issue 3 · 12 Apr 2019 · 8,072 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfiltration of Nanoparticles into Porous Binder Jet Printed PartsAmelia Elliott, Sarah AlSalihi, Abbey L. Merriman, Mufeed M. BastiThe densification of parts that are produced by binder jetting Additive Manufacturing (AM; a.k.a. “3D Printing”) is an essential step in making them mechanically useful. Increasing the packing factor of the powder bed by incorporating nanoparticles into the binder has potential to alleviate the amount of shrinkage needed for full densification of binder jet parts.
