Research ArticleOpen accessEvery word in the titleAugmented Reality Application for Teaching Basic Operations with Fractions of the Same DenominatorHernández Pérez Andrea Ivonne, Mendoza Pérez Marco Alberto, Cruz Flores René GuadalupeIn this study, an Augmented Reality (AR) application for the teaching of basic operations with fractions of the same denominator was made. Prototype Methodology was used for its develop. In the application striking figures designs are visualized in three-Dimensional (3D), to the students’ perspective, those help to represent the explanation in the best way with the process of the basic … …Journal of Computer Science, Vol. 16, Issue 7 · 13 Jan 2021 · 7,441 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effect of Heat or Heat-Xylose Processing on Nitrogen Fractions and in Situ/In Vitro Ruminal and Post-Ruminal Protein Disappearance of Guar MealHossein Jahani-Azizabadi, Mohsen Danesh Mesgaran, Ali Reza Vakili et al.Problem statement: Guar meal is a by-product consisting of hull and germ and is mostly used as a protein source in poultry and ruminant rations. The aim was to determine the effect of heat or heat-xylose processing on nitrogen fractions, in situ ruminal degradation parameters and in situ/in vitro ruminal and post-ruminal disappearance of guar meal. Approach: Samples were intact … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 27 Dec 2010 · 8,153 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Sturgeon Protein Fractions on Active Peptide Generation via Enzymatic HydrolysisMengjie Lu, Yingmei Hou, Yejing Sun et al.To identify the sturgeon protein component responsible for generating bioactive peptides, including antioxidant peptides and alcohol dehydrogenase (ADH) promoting peptides, sturgeon protein and its isolated protein components (sarcoplasmic, myofibrillar, and stromal proteins) were studied. Among the four isolated protein components, stromal protein demonstrated the highest susceptibility to enzymatic hydrolysis (P<0.05). Besides, pepsin and alkaline protease are the most effective enzymes … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 8 Apr 2026 · 1,419 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDevelopment of a Methodology for Determining the Nutritional Value of Pasture Feed Considering the Fractions of Easily Digestible Carbohydrates in the Desert Zone of Southern KazakhstanAmanbay Karynbayev, Beybit Nasiyev, Kuzembayuly Zharylkasyn et al.Due to the absence of easily digestible carbohydrates (sugar and starch, which are of great importance in animal nutrition) in the existing methods of assessing the nutritional value of feed, the need to include them in the methods for improving the overall nutritional value is a particularly urgent matter in feed manufacture for desert livestock industries. The study was carried … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 4 Sep 2023 · 4,882 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMutagenic Screening of Crude Oil Fractions Using Modified Ames Test and Allium cepa (Linn) AssayOlufunsho Awodele, Alade Akintonwa, Sunday O. Olayemi et al.Problem statement: Crude oil which may be broadly characterized as paraffinic or naphthenic is a complex mixture of alkanes, cycloalkanes and aromatic hydrocarbons. About 500,000 workers are employed in crude oil exploration and production worldwide. There have been reports of occupational exposure during drilling, pumping and transportation of crude oil, including maintenance of equipment used for these processes. Thus, skin … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 1 · 31 Jan 2010 · 8,629 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of the Prostatic Fluid from the First and Third Fractions of the Ejaculates on the Cryosurvival of Poodle Dog SpermHideaki Yamashiro, Kaori Narita, Satoshi Sugimura et al.Problem statement: Two experiments were conducted to determine the effect of the prostatic fluid from the first and third fractions of the ejaculates on the freezability of poodle dog sperm. Approach: The ejaculates from 2 trained poodle dogs were collected. Effect of prostatic fluid from the first and third fractions of ejaculates on cryosurvival of dog sperm was examined. SDS-PAGE … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 7,831 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAntispasmodic Activity of Persea cordata Vell. Mez. (Lauraceae) Fractions on Guinea Pig Ileum Induced by 5-Hydroxytryptamine and BradykininJúlio A. Zampirolo, Hellen K. Stulzer, Monika Piazzon Tagliari et al.Problem statement: Persea cordata previously demonstrated antispasmodic action against two neurotransmitters. It is important confirm such action against other neurotransmitters. Approach: Present study described the antispasmodic activity of polar (EtOAc; n-BuOH) and non polar (n-hexane; dichloromethane) fractions from the bark of Persea cordata, against guinea pig ileum contracted by 5-hydroxytryptamine (5-HT) and bradykinin (BK). Results: The results indicated that hexane … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 4 · 31 Dec 2008 · 7,400 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of the Use of Rice Bran Compost for Eco-friendly Weed Control in Organic Farming SystemsM.A.I. Khan, K. Ueno, S. Horimoto et al.Rice bran compost (RC) was evaluated under greenhouse and field conditions for eco-friendly weed control of vegetable crops in organic farming systems. RC was applied 7 days before spinach seed sowing, at the rate of 0% (control), 10%, 20% and 30% of soil (v/v) in the greenhouse and 2 kg m-2 under field conditions. RC significantly controlled the number and … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,927 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynthesis and Characterization of Cobalt, Iron and Ruthenium Catalysts for the Production of Synthetic DieselDayna M. Ortiz Rodríguez, María del C. Cotto-Maldonado, José Duconge Hernández et al.Fossil fuels are currently the world's leading source of energy. Environmental legislations, the high price of fossil fuels, the concern about the supply of these fuels and technological development, makes it necessary to search for alternative sources of energy. The production of clean liquid fuels, such as synthetic diesel from synthesis gas, by Fischer-Tropsch (FT) method, is considered a very … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 29 Apr 2020 · 7,248 accessesView PDFCite
