Research ArticleOpen accessAll words, across the recordIn Vitro Biological Profiles and Chemical Contents of Ethanolic Nest Entrance Extracts of Thai Stingless Bees Tetrigona apicalisTouchkanin Jongjitvimol, Sathirapong Kraikongjit, Pussadee Paensuwan, Jirapas JongjitwimolTetrigona apicalis is a species of stingless bees found in Lower Northern Thailand. They normally construct their nest entrances as an external structure for protecting themselves from enemies. Their biological properties have not well characterized yet. The objectives of this study were to evaluate the antibacterial, antifungal and anti-proliferative activities of their nest entrances. Samples were collected from four provinces … …OnLine Journal of Biological Sciences, Vol. 20, Issue 3 · 2 Nov 2020 · 6,781 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect 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 accessAll words, across the recordFormation Mechanism and Characterization of PANI Nanoparticles by Hybrid Chemical and Gamma Irradiation TechniqueShawkat Salameh GasaymehHere we present additional data regarding specific doping process in nanoparticle samples of PANI. In such technique, the ionizing γ-irradiation and (dodecylbenzenesulfonic acid), DBSA were being used as dopants and as accelerators to the oxidizing agent to polymerize aniline monomer into conductive PANI Emeraldine Salt (ES), in which PANI was produced from its monomer by this noble methodology by a … …American Journal of Applied Sciences, Vol. 15, Issue 12 · 13 Feb 2019 · 8,381 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExocellular (1→6)-β-D-Glucan (Lasiodiplodan): Carboxymethylation, Thermal Behavior, Antioxidant and Antimicrobial ActivityThais Vanessa Theis, Gabrielle Cristina Calegari, Vidiany Aparecida Queiroz Santos et al.β-Glucans are biomacromolecules of industrial interest for its biological and technological properties, including ability to modify the rheology of food systems and different biological functionalities. In this study, lasiodiplodan an exocellular polysaccharide of the (1→6)-β-D-glucan type produced by the fungus Lasiodiplodia theobromae MMPI was obtained in a bench-scale bioreactor operated in discontinuous mode. Lasiodiplodan produced was derivatized by carboxymethylation and … …American Journal of Immunology, Vol. 13, Issue 1 · 29 Mar 2017 · 8,326 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordUtilization of Sewage Sludge in Agricultural Soil as Fertilizer in the Republic of Benin (West Africa): What are the Risks of Heavy Metals Contamination and Spreading?Fidèle Suanon, Lyde A.S. Tomètin, Biaou Dimon et al.Biosolids are the treated organic residuals, also known as sewage sludge, which are generated from domestic wastewater treatment plants. It is an organic matter and nutrients [phosphorous (P) and nitrogen (N)]-rich material. Due to these properties, it is has been reported to be a suitable fertilizer or soil amendment which can valuably replace synthesized NPK. Unfortunately, this matter is heavily … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 6 Jan 2016 · 14,496 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordRegeneration of Lyes for Cleaning-In-Place (CIP) Processes in Dairies: Comparison of Recycled Potash and Soda Solutions Cleaning PropertiesMarie Furic, Anne Elain, Walid Blel, Olivier SireThe regeneration of lyes for their integration in the dairy CIP was investigated applying an original process combining adsorption/coagulation and flocculation operations. Solutions of potassium hydroxide (KOH) and caustic soda (NaOH) soiled with 1% (v/v) of whole milk were submitted up to twenty successive regeneration cycles. The multiple recycling of the regenerated solutions was found to modify their physicochemical characteristics … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 6 Jul 2015 · 6,624 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSIMULTANEOUS OPTIMISATION OF DRYING PARAMETERS OF CERAMIC BODIESSalah Mahmoudi, Ezzeddine Srasra, Fouad ZargouniThis study deals with the mineralogical, physico-chemical and geotechnical analyses of representative Aptian clays in the north-east of Tunisia. X-ray diffraction reveals a predominance of illite (50-60 wt.%) associated to kaolinite and interstratified illite/smectite. The accessory minerals detected in raw materials are quartz, calcite and Na-feldspar. The average amounts of silica, alumina and alkalis are 52, 20 and 3.5 wt.%, … …Current Research in Geoscience, Vol. 4, Issue 1 · 1 Jul 2014 · 6,991 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGROWTH OF YB3+ DOPED LiNBO3 CRYSTALS USING LASER HEATED PEDESTAL GROWTH METHODBariza Boudour, Youcef Boumaiza, Amar BoudourThe growth of LN single crystals free from defects greatly doped with rare earth elements (RE3+) and having a high optical quality is still an unresolved problem. Always, crystals of the niobate lithium contain a deficiency in lithium causing the appearance of intrinsic defects and thus a doping is required for the homogeneity. Our work was aimed to study the … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 17 Feb 2014 · 6,912 accessesView PDFCite
