Research ArticleOpen accessIn the abstractYeast Immobilization on Peanut Hulls for Potential Application in Beer FermentationWaldir D. Estela-Escalante, Sergio Rosales-Mendoza, Mario Moscosa-SantillánThe potential of using peanut hulls as support material for immobilization of yeast cells during beer fermentation was evaluated. After treatment of peanut hulls with 0.5% (w/v) NaOH, FTIR analysis revealed an important change on its chemical composition. For instance, the proportion of lignin decreased and as a result the adsorption of yeast cells onto the support material during fermentation … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 22 Jul 2019 · 8,378 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Usage of Biologically Active Raw Materials in Confectionery Products TechnologyAlfiya Chernenkova, Svetlana Leonova, Tamara Nikiforova et al.Increased man-caused impact, imbalance in diets lead to diseases, premature aging and life shortening. To overcome this imbalance, there is an active search for raw materials containing the physiologically functional ingredients necessary for human health or the raw materials containing biologically active substances, vitamins, mineral substances. To enrich traditional recipes with these components and to give functional purpose to products … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 7 Mar 2019 · 8,756 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntileishmanial and Antibacterial Activity of Essential Oils of Medicinal Plant Achillea santolina L.Abdulkarim Dakah, Mohammed MaarroufAchillea santolina is medicinal plant widely used in folk medicine for gastrointestinal disorders, anti-inflammatory and anti-diuretic. The World Health Organization (WHO) reports that about 350 million people are considered to be at risk of contracting leishmaniasis especially among people living in the developing countries. This research will be the first time that evaluate antileishmanial activity of essential oils of A. … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 2 Mar 2019 · 9,202 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Forensic Profiling of Primer-Derived Inorganic Gunshot Residues Using SEM-EDX SpectroscopyAhmed M. Bendary Salem, Aldo Barbaro, Bolaji OladipoGunshot Residue (GSR) analysis presents a significant challenge in forensic science due to the need to detect and identify minute traces of powders and initiating compositions formed during the chemical decomposition and deflagration processes within cartridge cases. This research is a qualitative comparative profiling study, designed to create a reference database of the most characteristic elemental markers for commonly used … …American Journal of Applied Sciences, Vol. 22, Issue 1 · 6 Mar 2026 · 2,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractGilsonite Modified Asphalt for Use in Pavement ConstructionAliasghar Akbari Nasrekani, Mostafa Nakhaei, Koorosh Naderi et al.Properties such as durability and moisture resistance of asphalt concrete significantly improve pavement service life. When siliceous aggregate is used, then preventing moisture damage and stripping become distinctly required. Typically, stripping could be prevented by either using antistripping agents or by modifying the binders. The anti-stripping agent achieve its purpose by changing the aggregates' affinity for water through changing the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 3 Apr 2018 · 9,387 accessesView PDFCite
Research ArticleOpen accessIn the abstractPetrography and Geochemistry of Orin-Ekiti Basement Rocks, Southwestern Nigeria: Implications on BauxitizationAbel Ojo Talabi, Akin Ojo Oyinloye, Olusola Amos Olaolorun et al.The petrography and geochemistry of Orin-Ekiti Basement rocks were evaluated to determine their mineralogical and chemical composition, assessed their petrogenesis and susceptibility to the formation of bauxitic clay. Ten representative rock samples were selected for thin section petrography and bulk rock geochemical analysis using Petrographic microscope and XRF, Rh Tube, 3k Watt respectively. Field observations revealed charnockites as the dominant … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 1 Jan 2018 · 8,769 accessesView PDFCite
Research ArticleOpen accessIn the abstractOvicide and Larvicide Activities of the Essential Oils Extracted from Polyalthia longifolia and Clausena anisata on Sitotroga cerealellaGuy Alain Alitonou, Jean Pierre Noudogbessi, Philippe Sessou et al.This work has objectives to study the chemical composition of volatile extracts obtained from leaves of Polyalthia longifolia and Clausena anisata and to evaluate their ovicide and larvicide effects by fumigation against Sitotroga cerealella, as alternative to the pesticides of synthesis. The analyses of the extracts by GC-MS showed that the essential oil of P. longifolia contains 57 compounds representing … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 19 Jul 2017 · 7,779 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiocompatibility of Orthodontic Resins: In vitro Evaluation of Monomer Leaching and Cytotoxic EffectsRoberto Uomo, Gianrico Spagnuolo, Giuseppina Nocca et al.The aim of this study was to investigate the effect of orthodontic resins on cell survival and to evaluate monomer leaching both before and after resin polymerization. Materials and methods: 3T3 mouse fibroblasts were exposed to three cured and uncured orthodontic resins. Cellular viability was assessed by Alamar Blue assay after 24, 48 and 72 h.

Research ArticleOpen accessIn the abstractDeposition and Characterization of CdS Nano Thin Film with Complexing Agent TriethanolamineK. Manikandan, C. Surendra Dilip, P. Mani, J. Joseph PrinceThe equimolar concentration thin films of Cadmium Sulfide (CdxSx) with the complexing agent TEA were deposited on a glass substrate by the SILAR technique. The crystalline nature with face centered cubic crystal system of the CdS films is determined from X-ray diffraction analysis. The broadened diffraction peaks indicated nano sized particles of the film materials. The surface morphology of the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 1 Jun 2015 · 8,426 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating Bio-Char as Flow Modifier and Water Treatment Agent for Sustainable Pavement DesignRenaldo Walters, Shamim A. Begum, Elham H. Fini, Taher M. Abu-LebdehThe life expectancy of Asphalt Binder (AB) has been negatively impacted by the harsh bombardment of Ultraviolet (UV) rays. UV rays cause asphalt to oxidize faster, which results in the deterioration of asphalt's rheological characteristics that can lead to pavement distresses. This paper investigates merits of bio-char to improve asphalt aging susceptibility by blending one control binder (PG 64-22) and … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 22 Apr 2015 · 9,055 accessesView PDFCite
