Research ArticleOpen accessEvery word in the titleEffect of Cinnamomum cassia Stem-Bark Extracts on the Synthesis and Secretion of Insulin in RIN-m5F CellsAnanias Hodi Kgopa, Sebolaishi Doris Makhubela, Motetelo Alfred Mogale, Leshweni Jerry ShaiCinnamomum cassia (C. cassia) crude stem-bark extracts possess some hypoglycemic properties through inhibiting the uptake of glucose by the intestines and/or enhancing insulin sensitivity. To further investigate the mechanism through which the hypoglycemic effect is exerted, this research explored the influence of the extracts of the crude stem-bark of C. cassia, with various polarities, on particular aspects of glucose consumption … …OnLine Journal of Biological Sciences, Vol. 22, Issue 2 · 5 Apr 2022 · 5,784 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effect of Bisphenol A Polyether Polyols on the Synthesis of Hydrophilic Epoxy ResinsJinhua Yi, Xin YuanThe article uses three types of Bisphenol A polyether polyols BEO, BPO-6 and BPO-10 as raw materials, reacts with epichlorohydrin under the action of a catalyst and synthesizes a hydrophilic epoxy resin. The molecular structure of the product is analyzed by infrared spectroscopy and the results show that the synthesis of the hydrophilic epoxy resin BEOGE conforms to the results … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 3 · 15 Jul 2021 · 7,659 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGeometric-Cinematic Synthesis of Planetary MechanismsNicolae Petrescu, Florian Ion Tiberiu PetrescuThe simple planetary mechanism is geometrically synthesized by determining the four tooth numbers of the component wheels. There are four main conditions that if not obeyed the mechanism will be blocked, will work with interruptions, or will not work at all. (a) The first condition in the geometric-kinematic synthesis of a simple planetary is the uniform loading of satellites (satellite … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 28 Aug 2018 · 7,458 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Synthesis of a Dual-Clutch Automatic GearboxesRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuRelatively recent have occurred dual-clutch automated boxes, which promise a lot in the field and can be used successfully in cars and trains as well as in the aerospace industry. This paper wants not only to present such a gearbox but also to realize its dynamic synthesis, based on the engineering optimization of the mechanical efficiency achieved in each used … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 8 May 2018 · 7,947 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Synthesis of a Classic, Manual GearboxRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuToday, various types of gearboxes have been introduced into the vehicles to change the way the classic manual gearboxes work, such as automatic gearboxes, semi-automatic, continuous variable, dual-clutch automatic gearboxes etc. However, most gear shifters for in-service vehicles are still classical manuals, which is why their optimal synthesis based on their dynamics and especially on optimal performance is now more … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 30 Apr 2018 · 8,634 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThermogravimetric Analysis (TGA) Profile at Different Calcination Conditions for Synthesis of PTES-SBA-15Norhasyimi Rahmat, Nurjihan Sadon, Muhammad Abeed YusofThe aim of this work is to study the effects of calcination condition on the properties of mesoporous silica, SBA-15 modified with phenyl group of organosilane. Functional group SBA-15 were synthesized and hydrothermally aged. The surfactant template was conventionally removed by calcination at varied temperature and duration. Thermogravimetric Analysis (TGA) was employed to characterize the pure and modified SBA-15. The … …American Journal of Applied Sciences, Vol. 14, Issue 10 · 7 Apr 2017 · 8,453 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Clean-Green Synthesis of Platinum Nanoparticles Utilizing a Pernicious Weed Lantana (Lantana Camara)Musthafa O. Mavukkandy, Sudip Chakraborty, Tasneem Abbasi, Shahid A. AbbasiA rapid, reproducible single step method is proposed for synthesizing platinum nanoparticles using an invasive weed lantana (Lantana camara, L). The method involves mixing of platinum (VI) solution, lantana leaf extract and ascorbic acid in appropriate concentrations and keeping the mixture at 95°C for 8 min. The collective action of ascorbic acid and leaf extract reduced the chloroplatinic acid to … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 23 Feb 2016 · 10,447 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLarge Scale Synthesis of ZnO Nanostructures of Different Morphologies through Solvent-free Mechanochemical Synthesis and their Application in Photocatalytic Dye DegradationRaúl Sánchez Zeferino, Jesús Alberto Ramos Ramón, Ma. Eunice de Anda Reyes et al.Well crystalline, near-stoichiometric zinc oxide nanostructures of different morphologies are fabricated in large scale, utilizing a simple, cost effective mechanochemical synthesis in absence of solvent. Effects of ionic and nonionic surfactants along with the concentration of hydrolyzing agent on the evolution of nanostructure morphology have been studied. It has been observed that while a cationic surfactant such as Cetyltrimethylammonium Bromide … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 16 Jan 2016 · 8,932 accessesView PDFCite
