Research ArticleOpen accessIn the abstractProcessability of Bulk Metallic GlassesRaffaella Aversa, Daniela Parcesepe, Relly Victoria V. Petrescu et al.Microfluidic Shear Flow Instabilities in Injection Molded Glassy Metal are investigated. The formation of microfluidic shear flows instabilities involving the presence of different viscosities fluids has been observed in injection molded Bulk Metallic Glasses. The complex rheology of injection molded metastable glassy metal, which has been hypothesized to induce selective clustering of atoms of different steric hindrance, is discussed. Smaller … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 15 Feb 2017 · 7,493 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Biodiesel Production from Spent Palm Cooking Oil Using Fractional Factorial Design Combined with the Response Surface MethodologyS.M. Zakir Hossain, Nahid Sultana, Muhammad Faisal Irfan et al.Fractional Factorial Design (FFD) of the experiments combined with the response surface methodology was used to determine the optimum conditions for the production of biodiesel from Used Cooking Oil (UCO) in a batch reactor. Spent palm olein cooking oil was used as a raw material for biodiesel production as it is commonly used in most of the restaurants in Bahrain. … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 22 Nov 2016 · 8,446 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact Behavior of High Strength Concrete Slabs with Pozzolana as Coarse AggregateMahmoud B.A. Alhasanat, Arabi N. Al QadiThis research goal is the adding of pozzolana as rough aggregate in concrete. Pozzolans of Jabl Onyzh have been described as the major supply from Jordan. It is often used in the place of a conservative aggregate in frivolous concrete. A practical examination was carried out on the resistance of Pozzolana Lightweight Concrete (PLWC) with diverse ratios (35 and 50%) … …American Journal of Applied Sciences, Vol. 13, Issue 6 · 14 Jun 2016 · 7,126 accessesView PDFCite
Research ArticleOpen accessIn the abstractOil and Fatty Acids in Seed of Eggplant (Solanum melongena L.) and Some Related and Unrelated Solanum SpeciesRobert Jarret, Irvin Levy, Thomas Potter, Steven CermakThe seed oil content of 305 genebank accessions of eggplant (Solanum melongena), five related species (S. aethiopicum L., S. incanum L., S. anguivi Lam., S. linnaeanum Hepper and P.M.L. Jaeger and S. macrocarpon L.) and 27 additional Solanums pecies, was determined by NMR. Eggplant (S. melongena) seed oil content varied from 17.2% (PI 63911317471) to 28.0% (GRIF 13962) with a … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 4 May 2016 · 8,499 accessesView PDFCite
Research ArticleOpen accessIn the abstractFactors Affecting Chemo-physical and Rheological Behaviour of Zr44-Ti11-Cu10-Ni10-Be25 Metal Glassy Alloy Supercooled LiquidsApicella Antonio, Aversa RaffaellaSegregation by selective cold crystallizations and glass transition changes in Zr44-Ti11-Cu10-Ni10-Be25 metal supercooled metastable liquid annealed at different temperatures have been theoretically correlated to melt viscosity modifications. Crystallization behavior has been found to be principally related to the high mobility and smaller Be, Cu and Ni atoms. Multiple exothermal peaks in isothermal DSC annealing’s have been observed in these bulk … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 25 Feb 2016 · 8,148 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of the Fatty Acid Profile in Some Macroalgae in Relation to the Environmental Conditions for Biodiesel ProductionNayrah Abdel Naby Shaltout, Nihal Galal Shams El-DinIn this study, fatty acids profile was determined in four algal species; namely Ulva fasciata (Chlorophyta), Corallina mediterranea, Corallina officinalis and Pterocladiella capillacea (Rhodophyta) which were collected from two sites (Abu-Qir Bay and Eastern Harbor) located on the Egyptian Mediterranean Sea during the four seasons in the period (2011-2012). In addition, nutrient content in the algal species (total nitrogen and … …American Journal of Environmental Sciences, Vol. 11, Issue 6 · 14 Dec 2015 · 7,338 accessesView PDFCite
Research NotesOpen accessIn the abstractPolymerisation and Oxidation of Docosahexaenoic AcidBrian Mundell Ross, Shelly Lynn Browning, Adrian McKeeOils rich in polyunsaturated fatty acids, such as linseed oil, can oxidise to form polymers. These can be used as protective coatings and act as an alternative to those derived from petrochemicals. Such renewable source oils usually require the addition of metal ions as catalysts of the polymerisation process and/or the partial pre-oxidation of the oil before use. We hypothesised … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 11 Dec 2015 · 7,621 accessesView PDFCite

Research ArticleOpen accessIn the abstractDynamic Mechanical Properties of Fused Deposition Modelling Processed Polyphenylsulfone MaterialBolin Huang, S.H. Masood, Mostafa Nikzad et al.Fused Deposition Modelling (FDM) has attained its reputation due to the capability of rapidly fabricating prototypes from concept design to real parts in shorter time and lower cost than traditional manufacturing processes. This study sheds light on the dynamic mechanical properties of Polyphenylsulfone (PPSF) material fabricated by FDM additive manufacturing process considering the effect of its various process parameters.

Research ArticleOpen accessIn the abstractInvestigating Effects of Application of Silica Fume to Reduce Asphalt Oxidative AgingNader Abutalib, Elham H. Fini, Sassan Aflaki, Taher M. Abu-LebdehThis paper investigates the feasibility of using silica fume to enhance the rheological properties of asphalt binder. It has been widely reported that asphalt binder oxidation is one of the phenomena that reduces the service life of asphalt pavement by negatively impacting its rheological properties. This in turn can lead to a more brittle pavement which is more prone to … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 22 Apr 2015 · 8,492 accessesView PDFCite
