Research ArticleOpen accessEvery word in the titleA Novel Characterization of the Incidence Term in Epidemic Models: Interpretation of the Resulting Basic Reproduction Number in Terms of Healthcare AccessibilityFrancis BenyahWe propose a novel characterization of the incidence term in mathematical epidemic models. This new characterization takes into consideration the fact that at any given time, only a proportion $\kappa \ (0 \, \le \, \kappa \, \le \, 1)$, of infectives have access to healthcare. Infectives without access remain untreated and therefore, become reservoirs for new transmissions.The proposed incidence … …Journal of Mathematics and Statistics, Vol. 22, Issue 1 · 1 Oct 2026 · 582 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSlime Mould Reproduction: A New Optimization Algorithm for Constrained Engineering ProblemsRajalakshmi Sakthivel, Kanmani SelvaduraiIn recent explorations of biologically inspired optimization strategies, the Slime Mould Reproduction (SMR) algorithm emerges as an innovative meta-heuristic optimization technique. This algorithm is deeply rooted in the reproductive dynamics observed in slime molds, particularly the intricate balance these organisms strike between local and global spore dispersal. By replicating this balance, the SMR algorithm deftly navigates between exploration and exploitation … …Journal of Computer Science, Vol. 20, Issue 1 · 21 Dec 2023 · 5,943 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBroodstock Formation and Sterlet (Acipenser ruthenus) Reproduction in the West-Kazakhstan RegionGuldana Maratkyzy Maratova, Kuanysh Isbekov, Shokhan Alpeisov et al.A dramatic decline of sturgeons’ stocks including the sterlet (Acipenser ruthenus) in the Caspian Sea including creates the need to establish aquaculture broodstock. Broodstock management can allow conserving the gene pool of the sterlet and the creation of captive broodstock further serve as a source of sterlet fry aimed at restoring natural populations of the sterlet in the Caspian Sea. … …OnLine Journal of Biological Sciences, Vol. 23, Issue 3 · 11 Jul 2023 · 5,321 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Increase of Madura Cows Reproduction Performance with Double-Dose Method of Artificial InseminationKuswati, Wike Andre Septian, Khairul Rasyad et al.One of the potencies of Madura cow genetics is its adaptation ability to the tropical climate. Yet in most cases, the reproduction efficiency of the Madura cows has not reached the optimum point. This research examines the use of double-dose artificial insemination compared to a single-dose on Madura cows. The study was conducted in Daramista, Lenteng District, Sumenep Regency, Madura, … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 3 · 2 Aug 2022 · 6,163 accessesView PDFCite
Literature ReviewOpen accessEvery word in the titleOzone Therapy: Overview of its Potential Utility in Male ReproductionZaher Merhi, Ali Bazzi, Rajean Moseley-LaRue et al.Ozone (O3), a highly water-soluble inorganic molecule, is a gas made of three atoms of oxygen (O) with a cyclic structure. Ozone can be produced by medical generators from pure oxygen after passing through a high voltage gradient. Ozone therapy (OT) can be given in medical practice via several routes that include transdermal, intramuscular, rectal, nasal, oral, vaginal, intravenous, intra-arterial, … …American Journal of Immunology, Vol. 14, Issue 1 · 4 Jan 2019 · 9,586 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProduction and Reproduction of Primiparous Guinea Pigs Concerning Lysine LevelsYasmeen Camila Vargas-Jauja, Karin Marleny Casilla-Huallpa, Liz Beatriz Chino-Velasquez et al.The development of breeding animals is essential to ensure the productivity of guinea pigs, so an adequate supply of nutrients is required. However, information on their nutritional requirements is limited, particularly with regard to amino acids such as lysine, wich affects their productive performance. We evaluated the effects of dietary lysine levels (0.84, 1.01, 1.18, and 1.34%) on prim parous … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 2 · 28 May 2025 · 5,467 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigation of Factors Influencing the Reproduction of Non-Gregarious Locust Pests in Northern Kazakhstan to Substantiate the Forecast of their Number and Planning of Protective MeasuresKurmet Baibussenov, Aigul Bekbaeva, Valery Azhbenov et al.The article presents the results of many years of research on the phytosanitary state of agricultural land for non-gregarious locust pests. As polyphagous pests, non-gregarious locusts are one of the key destabilizing factors in the production of economically important agricultural plants in the agricultural regions of Northern Kazakhstan. Research on the long-term population dynamics of non-gregarious locust pests to determine … …OnLine Journal of Biological Sciences, Vol. 21, Issue 1 · 17 Mar 2021 · 6,720 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAdjusted Transformation Methods for Reproduction Quality ControlEmmanouil-Nektarios Kalligeris, Alex Karagrigoriou, Kostantinos Ladopoulos, Christina Parpoulan this paper we introduce adjusted transformation methods for off-line quality control. The proposed methods result in proper performance measures for the determination of the controllable factors that affect the mean and variability of the response variable of interest. The details of the proposed adjusted transformations are provided and compared with the well-known Box and Coxtransformation and the safeguard method … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 22 Oct 2019 · 6,873 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAltered Reproduction in Clarias gariepinus Exposed to Industrial EffluentsAdeogun Aina Olubukola, Chukwuka Azubuike VictorProblem statement: Reproductive success is a key factor in determining species survival and the unregulated discharge of industrial effluents into rivers and streams in a developing country like Nigeria, can impair reproductive ability in non-target organisms like fish. Fish, generally accumulate contaminants from their environment in their tissues and these can be transmitted through the yolk lipids to the eggs. … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 21 Feb 2012 · 7,706 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImpacts of Social Origin on the Academic Career of University Students. The Case of the Faculty of Sciences of Ben M'SickElhassan Aamro, Jabran Daaif, Mohammed Talbi et al.Inequality of educational opportunities according to parental background is one of the most studied and debated topics in social sciences. Educational success remains strongly correlated with social background. The principle of equality among students, who are supposed to receive the same education regardless of their individual and family characteristics, is undermined by the exclusion mechanisms at work in Moroccan schools. … …Journal of Computer Science, Vol. 19, Issue 2 · 5 Feb 2023 · 5,820 accessesView PDFCite
