Research ArticleOpen accessIn the abstractEnhanced Antibacterial Activity of Blended Essential Oils against Staphylococcus Aureus and Methicillin-Resistant Staphylococcus AureusMin-Gi Kwon, Ji-Hyuk Kang, Jae Kyung KimWe aimed to evaluate the antibacterial effects of four blended and four single essential oils on the gram-positive bacterium Staphylococcus aureus (S. aureus) and methicillin-resistant S. aureus (MRSA). Minimum inhibitory concentration (MIC) testing was performed using disk diffusion and broth microdilution methods according to the Clinical and Laboratory Standards Institute criteria. The blended essential oils exhibited more powerful antibacterial activity … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 16 Apr 2026 · 1,597 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiomolecular Identification of Bacteria Endophytic From Betel Leaf in Jambi City Forest Park Area as Antibiotic-Producing PotentialArzita, Miranti Sari Fitriani, Nyimas Myrna Elsa Fathia et al.Background and Objective: Muhammad Sabki City Forest Park in Jambi City has three types of betel plants that contain endophytic bacteria. In 2021, six isolates of endophytic bacteria with the potential for producing antibiotics (halo zone above 10 mm) have been isolated, which can kill Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) test bacteria. that are 5 (five) isolates derived … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 15 Feb 2026 · 1,238 accessesView PDFCite
Research ArticleOpen accessIn the abstractTomato Leaf Disease Detection by Hybrid Ai and Ml TechnologyP. Loganathan, M. John Britto, Vinston RajaDiseases that affect plants contribute to productivity decline, but they can be managed with ongoing monitoring. It is time-consuming and prone to error to track plant diseases manually. Early disease detection using Artificial Intelligence (AI) and machine vision can lessen negative impacts while also overcoming some of the limitations of continuous human monitoring. Therefore, this study uses both Deep Learning … …Journal of Computer Science, Vol. 21, Issue 12 · 12 Feb 2026 · 1,889 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotentiometric Biosensor for Highly Toxic Pb (lead) and Cd (cadmium) Detection in Milk Using Layer-by-Layer ImmobilizationZhainagul Kakimova, Klara Zharykbasova, Aitbek Kakimov et al.Milk contamination with heavy metals such as lead (Pb) and Cadmium (Cd) poses a serious threat to public health, particularly in industrial regions. To address the need for rapid and on-site detection of these contaminants, a potentiometric biosensor was developed for the quantification of Pb²⁺ and Cd²⁺ ions in milk and dairy products. The biosensor functions by measuring the change … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 8 Feb 2026 · 1,484 accessesView PDFCite
EditorialOpen accessIn the abstractCommentary-How do we Improve Training for Receptor Research?Marilee Ann BenoreThis issue of the American Journal of Biochemistry and Biotechnology features articles about receptor-ligand interactions that are critical to the wellbeing of all living organisms. The importance of the field of receptor research is supported by the large number of articles published in journals, the numerous specialty journals, the international conferences and the percentage of legal drugs on the market … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 4 · 8 Dec 2015 · 8,058 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncorporation of Bentazone with Exserohilum rostratum for Controlling Cyperus iriaFranklin Ragai Kundat, Loo Hong Shen, Osumanu Haruna AhmedProblem statement: Various methods are used to counter the population of Cyperus iria in rice fields and among the most common method are chemical approaches. Chemical control methods are preferred by rice farmers due to their efficacy, speed, ease of storage and affordable cost. The concern of chemical herbicides is on its effects on the environment. Less attention had been … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 5 Sep 2011 · 9,529 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Criteria for Slab Compaction of Laboratory Roller Compactor (Turamesin)R. Muniandy, F.M. Jakarni, S. Hassim, A.R. MahmudLaboratory experiments should simulate to a high degree the conditions in the field, especially in term of compaction procedures. Presently available laboratory compaction methods do not seem to be able to produce specimens that can truly represent the mixtures as it exists in the field, especially for Stone Mastic Asphalt (SMA) mixtures. SMA is highly dependent on the method of … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,121 accessesView PDFCite
Research ArticleOpen accessIn the abstractWelded Connections of Wind Turbine Towers under Fatigue Loading: Finite Element Analysis and Comparative StudyNafsika Stavridou, Evangelos Efthymiou, Charalampos C. BaniotopoulosIncreased contemporary energy needs have led to multiple investments on wind power plants and structural improvements are considered necessary for the construction of taller, more robust and more economical structures. Tubular steel wind turbine towers that are the prevailing structural configuration, demand welding of circular subparts to construct the tower structure. These circumferential welds between tower subparts and between the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 18 Aug 2015 · 8,899 accessesView PDFCite
Research ArticleOpen accessIn the abstractVariability of Hydraulic Conductivity Due to Multiple FactorsSanjit K. Deb, Manoj K. ShuklaSoil properties are greatly influenced by intrinsic factors of soil formation as well as extrinsic factors associated with land use and management and vary both in time and space. Intrinsic variability is caused by the pedogenesis and usually takes place at large time scales. The variability caused by extrinsic factors could take effect relatively quickly and could not be treated … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 13 Aug 2012 · 10,228 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomated vs. Manual Counting of Bacterial Colonies Using Hough Circle Transform: A Comparative Study for E. coli, S.aureus, and P.aeruginosaAreesha Rehman, Zikria Saleem, Jarrar Amjad et al.Bacterial colony enumeration is an essential stage in microbiological research, allowing susceptibility to antibiotics assessment, monitoring of the environment, and clinical diagnostics. This research compares automated bacterial colony counting using the Hough Circle Transform to traditional manual counting methods. Objectives include evaluating counting accuracy and efficiency. This study adopted the image processing approach to colonies of E. coli, S. aureus, … …Journal of Computer Science, Vol. 21, Issue 10 · 7 Dec 2025 · 2,397 accessesView PDFCite
