Research ArticleOpen accessEvery word in the titleClinical Pregnancy After Assisted Hatching Rate in Young women undergoing Intra Cytoplasmic Sperm InjectionMohammed Al-SunaidiProblem statement: The ability of a blast cyst to hatch, or escape, from the Zona Pellucida (ZP) that surrounds and protects the embryo during its first few days of development is one of many critical events that must occur for successful reproduction. Implantation of the embryo in the uterine lining is impossible unless hatching occurs. Hard or thick ZP will … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 13 Mar 2012 · 7,049 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWhy College or University Students Hate Proofs in Mathematics?Mbaïtiga ZacharieProblem Statement: A proof is a notoriously difficult mathematical concept for students. Empirical studies have shown that students emerge from proof-oriented courses such as high-school geometry, introduction to proof, complex and abstract algebra unable to construct anything beyond very trivial proofs. Furthermore, most university students do not know what constitutes a proof and cannot determine whether a purported proof is … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 8,853 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThermodynamic Inference of the Antioxidant Process of Malic Acid and Its Structural AnalogsHan Wu, Wenhao Dong et al.Two structural analogs of Malic Acid (MA), 2-isopropylmalic Acid (2-IPMA), and 3-isopropylmalic Acid (3-IPMA) were recently identified and separated from wine. Although they have been shown to have antioxidant activity, the mechanism of their actions is still unclear. Antioxidant activities of 2-IPMA and MA were tested through DPPH, ABTS, and PTIO methods and the antioxidant-related thermodynamic properties were evaluated using … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 30 Oct 2024 · 4,827 accessesView PDFCite
