Research ArticleOpen accessIn the keywordsParallel Two-Dimensional Quicksort Algorithm (PTSA)Hamed Al Rjoub, Ahmad Odat, Abdullah AudatIn this research, a Parallel Two-Dimensional Sorting Algorithm (PTSA) is presented that has better performance than the classical Quicksort, to sort a data vector of size n = r (rows) × c(columns). PTSA algorithm divides the input vector into n/r sub-vectors, which represents tow-dimensional vector of Slave Processor Elements (VPE ), the maximum number of VPE for parallel sorting is … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 6,862 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBasic and Reactive Dyes Sorption Enhancement of Rice Hull through Chemical ModificationSiew-Teng Ong, Pei-Sin Keng, Chnoong-Kheng LeeProblem statement: Many studies have been conducted on the removal of either anionic or cationic dyes. However, as a mixture of dyes does commonly exist together in wastewater, therefore it is of great interest to have a material that can remove both types of dyes. Approach: To prepare an inexpensive and efficient sorbent by chemically modifying rice hull for the … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,793 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMethods of Utilizing Tropical Peat Land for Housing SchemeYouventharan Duraisamy, Bujang B.K. Huat, Azlan A. AzizThis paper discusses some of the methods and recent technologies in utilizing cheap marginal land such as tropical peat for housing scheme. Buildings on peat are usually suspended on piles, but ground around it may still settle. Therefore a suitable method of construction should be tackle to overcome serious problem such as localized sinking and slip failure, massive primary and … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,674 accessesView PDFCite
Research ArticleOpen accessIn the abstractEquivalent Torsional-Warping Stiffness of Cores with Thin-Walled Open Cross-Section Using the Vlasov Torsion TheoryTriantafyllos Konstantinos MakariosIn order to calculate the equivalent torsional-warping stiffness of the Reinforced Concrete (RC) cores that have thin-walled open cross-section, a new analytical methodology, which combines the Vlasov torsion theory with the Bernoulli bending theory, is presented herein. As the basis of the calculations, we use the principal elastic reference system of the core from this we consider that is known. … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 2 · 23 May 2023 · 6,406 accessesView PDFCite
Research ArticleOpen accessIn the abstractGastroprotective Effects of β-sitosterol and β-sitosterol-3-O-β-D-glucopyranoside from Bridelia ferruginea Stem BarkEjike Marcellus Nnamani, Peter Achunike Akah, Charles Ogbonnaya Okoli et al.The methanol extract of Bridelia ferruginea Benth. (Euphorbiaceae) stem bark (BFME) was partitioned in chloroform-methanol-water (2:2:1) mixture to obtain the Chloroform (CF) and Aqueous Methanol (AMF) fractions. The BFME, CF and AMF were screened for antiulcer activity using indomethacin-induced ulcer as activity guide. The CF provided the highest gastroprotection and was subsequently fractionated in a silica gel (60-200 mesh) column … …American Journal of Pharmacology and Toxicology, Vol. 15, Issue 1 · 4 Jan 2021 · 7,788 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Ageratum conyzoides L. (Asteraceae) Phytochemical Composition as Quorum-sensing Inhibitors to Combat Antibiotic-resistant Bacterial InfectionsEli Compaoré, Lassané Ouedraogo, Ablassé Rouamba et al.The rise of antibiotic-resistant bacterial infections has intensified the search for plant-derived quorum-sensing (QS) inhibitors as alternative therapeutic strategies. Ageratum conyzoides L. has a long history of traditional use as an antimicrobial agent against multidrug-resistant pathogens, yet the phytochemical basis of its QS-inhibitory activity remains incompletely characterized. This study aimed to investigate the phytochemical composition of A. conyzoides and evaluate … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 3 Apr 2026 · 1,779 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Evaluation of RC Frames Strengthened with FRPs under Fire and Lateral LoadsReza Salehi, Abbas AkbarpourReinforced concrete is one of the most common structures in the world. These structures may be under extreme loading conditions such as earthquake or they may confront with other flooding, impact or even the fire load. In the term of fire load, RC structures are very sensitive and due to the brittle behavior, the fast collapsing happens. In this research, … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 27 Sep 2020 · 6,709 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeparation, Purification and Anti-aging Activity of Tobacco PolysaccharidesMengyue Huang, Jingwu Song, Shuaishuai Chang et al.To separate tobacco polysaccharides and investigate their antioxidant and anti-aging properties, crude tobacco polysaccharides were extracted from raw tobacco using hot water, followed by purification through DEAE-52 cellulose column chromatography. The molecular weight and monosaccharide composition of the isolated polysaccharides were analyzed using HPGPC and HPLC. The antioxidant activities of these tobacco polysaccharides were tested using DPPH, ABTS, hydroxyl radicals … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 15 Jan 2025 · 5,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Identification and Quantification of Marine Fish from Environmental DNA in Sulawesi Waters (Makassar Strait, Flores Sea and Bone Bay), IndonesiaNita Rukminasari, Andi Aliah Hidayani, Wilma Joanna Carolina Moka et al.The emergence of environmental DNA (eDNA) represents a recent methodological breakthrough for evaluating the presence of aquatic vertebrate species. This approach offers a relatively simple method with significant implications for conservation biology. Our study aim was to augment our understanding of marine fish biodiversity in Sulawesi waters. We employed eDNA metabarcoding to investigate fish biodiversity within Sulawesi waters, specifically focusing … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 5 Jul 2024 · 5,010 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption and Distribution of Selected High Molecular Weight Polycyclic Aromatic Hydrocarbons in a Typical Coastal Sand DepositUzoije Atulegwu Patrick, Ezenobi Chukwunoye ChristainContaminant migration study through soil medium is a veritable tool for a match towards sustainable groundwater protection. It is also essential to predict the fate and Transport of pollutants and to evaluate pollution risks. In this study, migration and distribution of High Molecular Weight (HMW) Polycyclic Aromatic Hydrocarbons (PAHs) through a coastal sand deposit of a wetland was investigated.
