Research ArticleOpen accessIn the abstractMechanical and Microstructural Characterization of Plasma Welded Joints of 18 Ni-300 Maraging Steels Subjected to RepairsPaulo Roberto Sakai, Deivid Ferreira da Silva, Milton Sérgio Fernandes de Lima et al.Among the ultra-high strength structural steels, 18Ni-300 Maraging steel is one of the most important for the naval and aerospace industries. For example, in the manufacture of motor envelopes Plasma Arc Welding-PAW processes are used with the keyhole technique. The joints are regions of high responsibility and undergo a non-destructive inspection according to the standardized technical criteria. If there is … …Journal of Aircraft and Spacecraft Technology, Vol. 5, Issue 1 · 19 Apr 2021 · 7,599 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Al based Composites Reinforced with FeAl Intermetallic Particles by Mechanical AlloyingSergio Rubèn Gonzaga Segura, Arturo Molina Ocampo, Renè Guardián Tapia, Alejandro Sedano AguilarIn this research project, Al matrix composite materials reinforced with 5 and 10 (wt. %) of FeAl intermetallic particles were synthesized by Mechanical Alloying (MA) at a speed of 250 RPM for 2, 5, 10 and 15 h of milling time. The results showed that composite materials can be obtained at low energy conditions with improved dispersion of the reinforcement … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 24 Mar 2021 · 6,886 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Niobium Oxide Incorporation on Optical Properties of Sodium Bismuth Borate GlassesHossam M. Gomaa, Saeid M. Elkatlawy, Ahmed H. El-DosokeyGlasses with the chemical compositions 60% B2O3-20% Na2O-(20-x) % Bi2O3-x% Nb2O5 (where, x = 0, 5, 10 and 15 mol. %), were prepared by fast quenching of their melts. Characteristics of the obtained solids were checked by XRD, FTIR and optical absorption spectroscopy. XRD data confirmed the amorphous nature of the glass samples. FTIR results revealed no changes in the … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 6 Jul 2019 · 7,228 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dayak Onion (Eleutherine bulbosa (Mill.) Urb) on Uterine wall and Lipid Profiles of Ovariectomized RatAmalia Purnamasari, Anton BahtiarMenopause is a physiologic condition, in which women no longer experience menstruation. Decreased estrogen during and after menopause causes structural, physiological and biochemical changes that alter the health of women in general, both in organs and non-reproductive organs. Dayak onion contains eleuterinol, an naphtoqunone derivative that can be as SERM. Therefore, we evaluated the effects of dayak onions on lipid … …OnLine Journal of Biological Sciences, Vol. 18, Issue 1 · 23 Dec 2017 · 9,996 accessesView PDFCite
Research ArticleOpen accessIn the abstractWeissella cibaria Fungistatic Activity against Fusarium spp. affecting Yellow PitahayaLeidy Johana Valencia-Hernández, Karina López-López, Liliana Serna-CockFungistatic activity of a Lactic-Acid Bacteria (LAB) was assessed in vitro while isolated from its rumen fluid, against Fusarium oxysporum and Fusarium fujikoroi, basal-rot related species in yellow pitahaya. Fed batch was used to reproduce said LAB. Fungistatic activity kinetic tests were performed on the ferment (S1) and on two of the fractions obtained through centrifugation, supernatant (S2) and biomass … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 10 Dec 2016 · 7,978 accessesView PDFCite
Literature ReviewOpen accessIn the abstractThe Effects of Glucocorticoids on Trabecular Meshwork and its Role in GlaucomaAlina GenisPrimary Open-Angle Glaucoma (POAG), an optic neuropathy that is a leading cause of irreversible blindness, has been studied extensively in hopes of better understanding its underlying mechanism. Glucocorticoids (GC) are commonly used to treat inflammatory ocular conditions but are also known to increase the risk of glaucoma by raising Intraocular Pressure (IOP) in susceptible individuals, leading to steroid-induced glaucoma. Based … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 4 · 14 Oct 2015 · 8,219 accessesView PDFCite
