Research ArticleOpen accessIn the abstractEffect 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 PDF Cite

Research ArticleOpen accessIn the abstractAssessment of Strength Development in Stabilized Soil with CBR Plus and Silica SandSeyedesmaeil Mousavi, Aliakbar KaramvandThis paper investigates the potential use of a nano polymer stabilizer, namely CBR PLUS for stabilization of soft clay and formulation of an optimal mix design of stabilized soil with CBR PLUS and silica sand. The highway settlements induced by the soft clay are problematic due to serious damages in the form of cracks and deformation. With respect to this, … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 12 Apr 2017 · 7,889 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAcid-Base Buffering Properties of Five Legumes and Selected Food in vitroMaher M. Al-Dabbas, Khalid Al-Ismail, Ruba Abu Taleb, Salam IbrahimProblem statement: in vitro acid-Buffering Capacity (BC) values of 5% (dry matter) aqueous homogenized suspension of five legumes (broad bean, lentils, chickpea, kidney bean and lupine) and of selected antacid home preparations (cow's milk, almond, peanut, licorice, carob and lettuce stem) were investigated within and among samples from their respective initial pH until pH was decreased to 1.5. BC was … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 21 Jun 2010 · 9,737 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordCharacterization of Fructan Content from Stem Juices of Different Varieties of Agave Atrovirens, Traditionally Used for the Production of Pulque. Production of a Sweetening Syrup by Chemical and Enzymatic ProcessingKaren Gott-Bravo, Arnulfo Pluma-Pluma, Victor Eric López-López et al.Agave atrovirens, the hardiest species of Agave in Mexico, thrives in tough, infertile soils and extreme temperatures across a wide range of altitudes, particularly in impoverished rural areas of Central and Northern Mexico. Its potential for agroindustrial use could offer a pathway to social and economic prosperity for many communities. Traditionally, A. atrovirens is tapped for its sap, known as … …American Journal of Agricultural and Biological Sciences, Vol. 19, Issue 1 · 4 Mar 2025 · 7,670 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordCurrent Growth Conditions of Populus Diversifolia Schrenk and Populus Pruinosa Schrenk in the Syr-Darya ValleyPolina Vesselova, Karina Makhmudova et al.In the context of urbanization of territories and the intensification of agriculture, the biological diversity of animals and plants in their habitats is degrading. The purpose of the study is to determine the edaphic factors affecting the growth of Populus diversifolia Schrenk and Populus pruinosa Schrenk, as well as anthropogenic factors affecting their conservation in the Syr-Darya valley (Kazakhstan).

Research ArticleOpen accessAll words, across the recordEffect of Low Temperature on the Fabrication of Microring Resonator by Wet EtchingHazura Haroon, Sahbudin Shaari, P. Susthitha Menon et al.Research related to semiconductor devices often relies on wafer fabrication. The fabrication of Silicon (Si) based devices by anisotropic wet etching can be affected by many etching parameters such as etching temperature, crystal orientation and percent of composition. Most of the anisotropic wet etchings by KOH solution done before were conducted at temperature over 70°C. We found that the temperatures … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 7 Nov 2012 · 7,126 accessesView PDF Cite
