Research ArticleOpen accessIn the abstractAdvanced Manufacturing for Novel Materials in Industrial Design ApplicationsFrancesco Tamburrino, Antonio Apicella, Raffaella Aversa, Florian Ion Tiberiu PetrescuThe research presented starts with a focus on Smart Materials, or rather materials with properties that react to external stimuli (temperature, electric or magnetic field, pH or mechanical stress, for example) related to the environmental changes, modifying one or some of their own properties (mechanical, electrical, appearance, etc.). Afterward, one category of Smart Materials, Shape Memory Alloys (SMAs), has been … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 30 May 2018 · 8,540 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Identification of Staphylococcus epidermidis S14 Screening Extracellular Antimicrobial MetabolitesJie Zhang, Han Jiang, Jiaxin Jiang, Guangrong HuangTotal 24 isolates with antimicrobial activity against Staphylococcus aureus, Escherichia coli, Bacillus cereus and Shigella castellani, out of 259 strains, were isolated from the internal of seven marine fishes. The extracellular metabolites of strain S14, isolated from the internal of shark, showed stronger inhibition against the four tested bacteria, including G- and G+ bacteria. Based on the 16S rDNA the … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 19 Mar 2016 · 7,573 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluences of Short Discrete Fibers in High Strength Concrete with Very Coarse SandMahyuddin Ramli, Kwan Wai HoeProblem statement: High Strength Concrete (HSC) normally content high cementitous amount and low water binder ratio. However, these would cause substantial volume changes to the concrete and therefore affected the strength development. In addition, the brittleness of HSC was increased when silica fume used as partial cement replacement to achieve high strength. Approach: This study discussed the effects of incorporated … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractRational Mix Design Approach for High Strength Concrete Using Sand with very High Fineness ModulusKwan Wai Hoe, Mahyuddin RamliProblem statement: Production of concrete is always deal with inconsistency. Sources of variation like materials from different geographical basis, mix design method, fineness of aggregates and so on will attribute to different level of achievement of the concrete. Even though researcher had verified that higher fineness modulus of sand would yield better performance for the concrete, but so far there … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 8,222 accessesView PDFCite
Research ArticleOpen accessIn the abstractPowerful Features of the Modern Syllogistic Method of Propositional LogicAli Muhammad Rushdi, Omar Mohammed Ba-RukabIn traditional propositional logic, many replacement and inference rules were involved to ascertain if the truth of several antecedents implied the truth of a particular consequent. This research described a powerful technique called the Modern Syllogistic Method (MSM), which ferreted out from a set of premises all that can be concluded from it and casted the resulting conclusions in the … …Journal of Mathematics and Statistics, Vol. 4, Issue 3 · 30 Sep 2008 · 7,111 accessesView PDFCite
Research ArticleOpen accessIn the abstractVariations in Four Genotypes of Lentil under NaCl-Salinity StressM. Sidari, C. Santonoceto, U. Anastasi et al.Four lentil cultivars, Eston (E), Rossa of Castelluccio (RC), Pantelleria (P) and Ustica (U) differing in salt sensitivity, were examined for osmolyte contents and activities of α-amylase, β-amylase and α-glucosidase enzymes involved in seed germination, in absence as well as in presence of 50, 100, 150 and 200 mM NaCl. The inhibitory effects of NaCl differed, depending on the genotypes … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,711 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of the Mandibular Glands of Ant Workers Atta sexdens rubropilosa (Forel, 1908) (Hymenoptera: Formicidae) Focusing the Ultrastructural CytochemistryLorena Favaro Pavon, Maria Izabel Camargo MathiasThe mandibular glands of hymenopterans in general are paired structures located on each side of the head. These glands possess an excretory duct located at the internal surface of the mandible articulation, through which these glands release the secretion they produce. The mandibular glands of the minima, media and soldier worker of the ant Atta sexdens rubropilosa were analyzed by … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 2 · 30 Jun 2006 · 7,648 accessesView PDFCite
