Research ArticleOpen accessPhrase in the titleModel Checking the Biological Model of Membrane Computing with Probabilistic Symbolic Model Checker by Using Two Biological SystemsRavie Chandren Muniyandi, Abdullah Mohd. Zin, Zarina ShukorProblem statement: Membrane computing formalism has provided better modeling capabilities for biological systems in comparison to conventional mathematical models. Model checking could be used to reason about the biological system in detail and with precision by verifying formally whether membrane computing model meets the properties of the system. Approach: This study was carried to investigate the preservation of properties of … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 6,672 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Challenge of the Hospitals and Health Care Systems in Preparation for Biological and Chemical Terrorism AttackEldo Ermenegildo Frezza MDIn the present study a few aspects of planning for terrorism events that expose large numbers of people to contamination are discussed. Many issues were considered as an absolute requirement for implementation of NBC response: 1) policy, 2) plan and 3) emergency department response to surge capacity. Key elements of the healthcare facility response plan include prompt recognition of the … …Journal of Social Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,390 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePlants Responses to Nutrients Follow the Saturation Kinetic Typical of Enzyme Systems: Biological, Economical and Environmental ImplicationsR.P. LanaAgricultural efficiency has been associated with high plant productivity. However, it is dependent on fertilizers, which are nonrenewable resources. Crop production response to fertilizers is hyperbolic, following the Michaelis-Menten model and the law of diminishing return. Data of crop production (barley, bean, corn, cotton, soybean and wheat) as a function of nitrogen, phosphorus, and potassium fertilization were analyzed by Lineweaver-Burk … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 6,895 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Theory of the Mind as a Complex SystemCraig P. Speelman, Kim Kirsner, Stephan HalloyFive principles of skill acquisition are presented based on a review of research on human learning and expertise. Essentially these principles state that practice leads to faster and more efficient uses of knowledge. This enables faster performance and results in less demand on mental resources. In turn these outcomes enable higher level behaviours to be attempted. Ultimately skills are developed … …Current Research in Psychology, Vol. 3, Issue 1 · 9 Jul 2012 · 9,149 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSilicone Modeling of the Interior Spaces of Hollow Organs: Use in Dog and Manatee Respiratory Tract and in a Beef HeartCharles J. Grossman, Richard Hamilton, Lisa A. Close-Jacob et al.Problem statement: The mechanism, by which the Florida manatee (Trichechus manatus latirostris) vocalizes, remains unknown because the manatee larynx does not contain true vocal cords. Since sound can be generated when air passes through a narrow respiratory structure we needed to visualize the internal anatomy of manatee respiratory tract to locate any candidate regions for study. Approach: To visualize the … …OnLine Journal of Biological Sciences, Vol. 11, Issue 1 · 6 Jul 2011 · 7,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractPossibilities of Stabilizing Soil Biological Activity by Treating Seeds With a Biological Preparation Based on Phosphate Mobilizing Bacteria in the Conditions of the Aral Sea Region of KazakhstanZhanar Zhumadilova, Laura Tokhetova, Shorabayev Yerik et al.This study examined the effect of Phosphate-Mobilizing Bacteria (PMB) as a pre-sowing treatment for forage crop seeds. The objective was to assess the potential of these bacterial biopreparations to improve both crop productivity and soil fertility. Research methods included agrochemical, microbiological, and conventional field analyses. The findings revealed that pre-sowing seed treatment with PMB increased crop yields by 7.4% to … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 24 Sep 2026 · 642 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Monitoring of Endocrine-Disrupting Chemicals: Analytical Chemistry and Biological Assessment ApproachesChangjin Li, Jing Huo, Zijun Dou et al.Endocrine-Disrupting Chemicals (EDCs) in aquatic environments pose significant threats to ecosystems and human health. These compounds interfere with hormonal regulation at low concentrations and have non-monotonic dose-response relationships, posing challenges to conventional risk assessment. This review systematically compares current EDC monitoring methods, including instrumental chemical analysis and receptor-based biological detection systems, to evaluate sensitivity thresholds, sample throughput, and mechanistic selectivity … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 3 Jul 2026 · 1,081 accessesView PDFCite
Research ArticleOpen accessIn the abstractAlgorithmization of Electrostatic Model for Solving the Direct Problem of ElectrographyTagirbek Gaidarbekovich Aslanov, Naur Zamirovich Ivanov, Shamil Shamil`evich Anudinov, Tatiana Vladimirovna KarlovaAn analysis of the creation and implementation of algorithms to control cardiological processes occurring in the cardiovascular system using software and hardware diagnostic systems is a required activity. This study considers ways to improve the methods of medical data processing using electronic diagnostic systems, relying on existing methods of mathematical simulation of human body states. This study describes the development … …Journal of Computer Science, Vol. 21, Issue 4 · 7 Mar 2025 · 5,330 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntioxidant Activity of Trilobatin and Its Inhibitory Effects on Oxidative Damage of Biological MacromoleculesYuhan Zhai, Yuqing Zhang, Yaping Li et al.Excessive levels of free radicals in the body cause oxidative damage to macromolecules by injuring DNA, proteins, and lipids, which leads to structural and functional defects and ultimately results in a number of illnesses. The antioxidation of trilobatin and its inhibitory activity of trilobatin on oxidative damage of biological macromolecules have not been thoroughly investigated. In this research, the effects … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 4 · 28 Oct 2023 · 5,466 accessesView PDFCite
Research ArticleOpen accessIn the abstractCytotoxicity Evaluation of Curcumin-FITC Conjugates in Granulosa Cells Isolated from Ovarian Follicles of Kampung Chicken (Gallus gallus domesticus)Sukarman Hadi Jaya Putra, Mansur S, UmarudinLinking curcumin to fluorescein isothiocyanate (FITC) results in a hybrid fluorescent marker (curcumin-FITC) that exhibits improved stability and sensitivity in detection. This study sought to evaluate the biological safety and cytotoxic effects of curcumin-FITC on granulosa cells obtained from ovarian follicles (2-5 mm, F1-F4 stage) of Kampung chickens.
