Research ArticleOpen accessIn the keywordsReliability Equivalence Factors of a System with m Non-Identical Mixed of LifetimesAbdelfattah Mustafa, Adel A. El-FaheemProblem statement: The aim of this study is to generalize reliability equivalence technique to apply it to a system consists of m independent and non-identical lifetimes distributions, with mixed failure lifetimes f1(t),f2(t),…,fm(t). Approach: We shall improve the system by using some reliability techniques: (i) reducing the failure for some lifetimes; (ii) add hot duplication component; (iii) add cold duplication component; … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,302 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethodological Approach to Developing a Model of Interference-Free Processing of Multichannel Records of the Electrical Cardiological Impulse to Determine Episodes of Cardiac Muscle IschemiaSergey Alexandrovich Sheptunov, Alexander Nikolaevich Muranov, Abas Khasanovich Lampezhev, Tagirbek Gaidarbekovich AslanovThis study considered a set of topical issues aimed at improving the methodology of the early recognition of episodes of myocardial ischemia. It aims to solve a set of problems in the substantiation and development of a methodological approach for building a model of interference-free processing of multichannel electrocardio signal recordings. Based on theoretical and experimental studies, this will create … …Journal of Computer Science, Vol. 21, Issue 5 · 14 Apr 2025 · 4,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractTheoretical Construction of Job Satisfaction of Workers of Creative Industries in Mexico CityMaría del Carmen López-GarcíaJob satisfaction is a concept studied since 1935 by both qualitative and quantitative studies. It is defined as a man's attitude towards his work. The objective of this study was to analyze the theoretical construction of job satisfaction that has been developed by the workers of the creative industries who live in Mexico City. The qualitative method of the informed … …Journal of Social Sciences, Vol. 17, Issue 1 · 6 Feb 2021 · 7,649 accessesView PDFCite
Research ArticleOpen accessIn the abstractTheoretical Investigation of Two Antiemetic Drugs at DFT LevelKhalil Errahmane Kanouni, Yacine BenguerbaThe geometries and the bonding properties have been predicted for two antiemetic drugs using Density Functional Theory method (DFT). Mulliken population and frontier molecular orbital analysis with the determination of the physicochemical properties was performed using the Amsterdam Density Functional package (ADF). To calculate the exchange-correlation energy, the Generalized Gradient Approximation of Becke-Perdew (GGA-BP) was used. The most important finding … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 14 May 2020 · 11,496 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe End of the Middle as we know it a Cross-Sectional Comparison of Political Polarization among College Students in 2005 and 2020Sara Holland Levin, Kristine Nowak, Christian RauhThe growing political polarization in America is demonstrated in many ways, including through increased salience and extremity of political identity. According to social identity theory, people are more likely to view ingroup members positively, and outgroup members negatively, especially when that group identification is particularly salient. This paper examines the evolution of political identity by reporting on surveys of college … …Journal of Social Sciences, Vol. 22, Issue 1 · 25 Jun 2026 · 1,536 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphological Diversity of Isolated Mycobacterial Cultures in the Republic of Kazakhstan: Implications for Diagnostics and TreatmentAssiya Borsynbayeva, Kairat Turgenbayev, Gulzhauhar Sarsenova et al.The study of mycobacterial morphology in the Republic of Kazakhstan is relevant due to the increasing burden of tuberculosis and other mycobacterial diseases. The aim of this study was to comprehensively describe the morphological characteristics of different mycobacterial species identified in Kazakhstan, which will help to improve diagnostic methods and develop new approaches to treatment. Comparative and cross-cultural analyses were … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 1 Dec 2025 · 2,203 accessesView PDFCite

Research ArticleOpen accessIn the abstractCrack Bridging and Deflection Toughening Mechanisms of Staggered Hydroxyapatite Lamellar Microstructure in BoneYuxi Liu, Xiaohui He, Shuge Li, Zhangdong SunThe observation experiment results of the microstructure of tibial cortical bone show that the cortical bone is a layered bio-ceramic composite material composed of Hydroxyapatite (HAP) and collagen arranged alternately. HAP is a reinforcing phase and accounts for a large proportion in cortical bone. These hydroxyapatites have long and thin sheet-like structures parallel to the outer surface of the bone, … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 31 Jul 2026 · 890 accessesView PDFCite
