Research ArticleOpen accessPhrase in the titleOn Some Stability Results for Fixed Point Iteration ProcedureM. O. Olatinwo, O. O. Owojori, C. O. ImoruIn this study, we establish that both the Mann and Ishikawa iteration processes are T-stable for the mappings T satisfying a more general contractive definition than that of Osilike[1] . The results obtained generalize some of the recent results of Osilike[1] which are themselves generalizations and extensions of some of the results of Harder and Hicks[2] and Rhoades[3,4]. …Journal of Mathematics and Statistics, Vol. 2, Issue 1 · 31 Mar 2006 · 7,042 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleSome Stability Results on Krasnolslseskij and Ishikawa Fixed Point Iteration ProceduresM. O. Olatinwo, O. O. Owojori, C. O. ImoruIn this study, we establish some stability results for the Krasnoselskij and the Ishikawa iteration procedures. We employ the same method as in Berinde[1], but using a more general contractive definition than those of Berinde[1], Rhoades[2], Harder and Hicks[3] and Osilike[4,5]. …Journal of Mathematics and Statistics, Vol. 2, Issue 1 · 31 Mar 2006 · 6,939 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Simple Algorithm to Assess the Speed Stability of Induction GeneratorsAlexandre de Assis Mota, Lia Toledo Moreira MotaProblem statement: The speed stability if Induction Generators (IG) can be defined as its ability to remain connected to the electric network, operating at a mechanical speed close to the speed associated to the actual system frequency, after being subjected to a perturbation. This IG behavior is normally studied using dynamical methods that are determined through time-consuming simulations and are … …Journal of Computer Science, Vol. 7, Issue 6 · 13 Jun 2011 · 6,554 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Metal Ions on The Functional Properties of Taro Protein IsolateYouru Huang, Yingtong Li, Zheng Zhang, Maoqiang ZhengThis study investigated the effects of metal ion species and concentrations on the functional properties of taro protein isolate (TPI), extracted from Colocasia esculenta corms. The results demonstrated that metal salt solutions could modulate the unfolding and aggregation of TPI, thereby altering its protein-protein and protein-water interactions and significantly affecting the functional properties. When monovalent cation concentration [M+] was less … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 6 Jan 2026 · 2,017 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation and Stability of Moisturizing Essence Liquid from Trollius Chinensis Bunge Stem ExtractXiyue Yu, Jiaqing Wu, Wenqiu Zhu et al.The stem, a byproduct of traditional Chinese herbal medicine Trollius chinensis Bunge, has not been effectively developed and utilized for a long time. In this study, the polysaccharides and flavonoids from Trollius chinensis Bunge was used as main ingredient in moisturizing essence liquid, and the preparation and stability of moisturizing essence liquid was studied. The approach was as follows: The … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 27 Mar 2025 · 5,262 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntroduction of the Pasture Plant Fescue (Festuca valesiaca) for the Improvement of Degraded Pastures in the Steppe Zone of KazakhstanMeldebekova Nurgul Alikhanovna, Seitbattalova Ainur Islamovna, Ainebekova Bakyt Alpysbaevna et al.This study presents the results of a comprehensive evaluation of Festuca valesiaca, a dominant perennial grass species widely used in steppe ecosystems for pasture improvement. Previous research has demonstrated the importance of native fescue species in enhancing productivity and resilience of degraded rangelands under arid conditions. However, breeding efforts for this species in Kazakhstan remain insufficiently developed. The research was … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 14 Sep 2026 · 667 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanism Analysis of Artemisinin and Artesunate as Lung Cancer Therapy Agents Through in Silico MethodDidik Harmoko, Vivitri Dewi Prasasty, Adi YulandiSeveral in vitro studies have focused on the ability of artemisinin and its derivatives to suppress lung cancer cells, but there are still many biological processes and mechanisms, such as the interactions between the active compounds (ligands) and receptors that are not well understood and require further research. Drug targeting for lung cancer will be more precise and the inhibition … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 15 Feb 2024 · 6,149 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Amylase Activity by Modulating Abiotic Factors and Enzyme Stability in the Thermophilic Bacterial IsolatesAnthoni Agustien, Denny Bendrianis, Feskaharny Alamsyah et al.Amylase is one of the enzymes that is widely used in bioprocess technology, amylase from different microbial sources also varies in form, so it is suitable for its specific application. The purpose of this study was to determine the optimum temperature, pH, agitation, and stability of the amylase enzyme from two thermophilic bacterial isolates, TUA-07 and TUA-09. This study used … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 7 Feb 2024 · 5,500 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Management and Fungicide Efficacy of Foliar Diseases in Spring Wheat in KazakhstanNadira Sultanova, Yerlan Dutbayev, Gulzada Abisheva et al.Spring wheat (Triticum aestivum L.) is a key economic crop in Kazakhstan. This study aimed to identify genetic sources conferring resistance to major foliar diseases and to quantify the contribution of fungicide application to yield stability. Field experiments conducted in 2024 assessed the resistance of 36 spring wheat genotypes, 17 common wheat and 19 durum wheat (T. durum Desf.), to … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 17 Jul 2026 · 967 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Multi Task Analysis Model Based on EEG Features in the Study of the Correlation between Depression and Sleep Disorders in College StudentsFeng MaWith the improvement of multi-modal technology, research on depression recognition combining multiple biological signal features has been increasing. Electroencephalogram signals reflect brain activity, and by analyzing their characteristics, the accuracy and stability of depression recognition can be effectively improved. Therefore, this study proposes a correlation analysis between depression and sleep disorders in college students based on electroencephalogram feature analysis, innovatively … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 2 Feb 2026 · 1,997 accessesView PDFCite
