Research ArticleOpen accessIn the keywordsCurrent State of a Rare, Narrowly Endemic Plant of the Flora of Kazakhstan, Rosa Potentilliflora Chrshan. et M. Pop. (Rosaceae) in Low-Mountain SyugatyChinargul Aldassugurova, Abibulla Ametov, Akmaral Nurmahanova, Aigul AkhmetovaThis study provides a comprehensive ecological assessment of Rosa potentilliflora, a rare and narrowly endemic species of the Kazakh flora, occurring exclusively in the Syugaty low-mountain range at the eastern edge of the Zailiyskiy Alatau. The species occupies southeast-facing rocky slopes within steppe vegetation belts. Three distinct cenopopulations were identified and studied using standard geobotanical and demographic methods. Within these … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 27 Nov 2025 · 2,023 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsNetwork Topological Property of English Dialects Similarity: A Robust Filter ApproachMaman Abdurachman Djauhari, Gan Siew LeeWe show that the common approach to use of Minimum Spanning Tree (MST) to filter the information contained in a complex system of English dialects similarity is not robust. Later on we propose a robust filter based on the forest of all possible MSTs. To illustrate the advantages of this filter, Morgan’s data on English dialects similarity is analyzed and … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 17 Jun 2013 · 6,588 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Components of Data Governance Framework for MOOC Providers in IndonesiaYakob Utama Chandra, Harjanto Prabowo et al.The COVID-19 pandemic had a universal and synchronous impact on all countries globally, leading to the implementation of the social distancing policy that mandated all activities take place within one's own house. One of the implementations is distance education. Since the pandemic, e-learning, which is the dominant use of information technology in the education sector, has gained widespread recognition and … …Journal of Computer Science, Vol. 20, Issue 12 · 31 Oct 2024 · 4,773 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Low Frequencies on Three Phase Induction Motor Performance Operating in Close Proximity to Rated SpeedQazem Jaber, Qais Naman, Mahdi ShamaseenVariable speed drives (VSD) are adhered to induction motors in most of the present industrial applications. And since the world has become more conscientious to energy saving, inverters established them selves in domestic buildings and industry. Square wave inverters generate dominant harmonics of the 5th, 7th, 11th and 13th order. Inverters based on PWM strategy produce much higher harmonic order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,516 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEFFICACY OF ESSENTIAL OILS FROM MEDICINAL PLANTS IN CONTROL OF THE HAIRY ROSE BEETLE, TROPINOTA SQUALIDA (SCOPOLI) AND THEIR COMPARATIVE TOXICITY TO THE HONEY BEE, APIS MELLIFERA L.Mohammad S. Al-AlawiThe insecticidal activity of essential plants oils against an important insect pest of fruit trees, the hairy rose beetle, was evaluated in topical and feeding applications in the laboratory. Essential oils that caused more than 50% mortality were further tested against the hairy rose beetle and the honey bee using different concentrations and their relative toxicities were evaluated. Results showed … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 18 Mar 2014 · 7,772 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Investigation of Compressed Natural Gas Engine for Nitrogen Oxides ReductionP. M. Diaz, B. Durga PrasadProblem statement: This study describes the use of Reformer Gas (RG) to alter NOx emission in a CNG-fueled HCCI engine. Comparison with diesel, natural gas has a very high octane number (≈120) and high auto-ignition temperature (≈600°C). Composed mostly of methane, natural gas is the only common fuel to manifest relatively pure, single-stage combustion. Other fuels have stronger low-temperature reaction … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 15 May 2012 · 7,298 accessesView PDF Cite
