Research ArticleOpen accessEvery word in the titleScanning Electron Microscopic Evaluation of Self-Compacting Concrete Spalling at Elevated TemperaturesMahmoud B. Alhasanat, Arabi N. Al Qadi, Omar A. Al Khashman, Ahmad DahamshehThis paper reports the effect of addition of Polypropylene (PP) fibers in the performance of Self-Compacting Concrete (SCC) under elevated temperatures. Various SCC mixtures were made with PP fiber at 0.0, 0.05, 0.10 and 0.15% by volume added. The specimens were exposed to elevated temperatures (200°C [392°F], 400°C [752°F] and 600°C [1112°F]). The microstructure of the matrix was investigated. This … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 7 Mar 2016 · 8,433 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleAutomatic Text Removal and Replacement in Scanned Meteorological Thematic MapsAhsan Abdullah, Sohyb Sami Abo Alshamat, Ahmad Bakhashwain, Ahtisham AslamGeo-referenced data is required in many Geographic Information System (GIS) applications and one source of such data being maps. Meteorological maps are color-coded with different regions corresponding to different values of a parameter, parsing the image to convert into data is not very difficult. However, text and different planimetric elements overlaid on the regions in the map makes accurate image … …Journal of Computer Science, Vol. 11, Issue 5 · 18 Aug 2015 · 7,045 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleTHE IMPACT OF ANTIOXIDANTS ON INFLAMMATION AND OXIDATIVE STRESS MARKERS IN OSTEOARTHRITIS RAT MODEL: SCANNING ELECTRON MICROSCOPE INSIGHTSEl Hassan Heidar, FareedF Al Faya, Waleed N. Hassan et al.Osteoarthritis (OA) is characterized by degradation of matrix and destruction of articular cartilage. Articular chondrocytes are solely responsible for the production and maintenance of the extracellular matrix. Therefore, chondrocyte disruption is implicated in cartilage degeneration. Numerous studies have shown that antioxidant treatments are promising therapeutics in cases of OA. This study was designedto examine whether vitamin E protects rat articular … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 2 · 19 May 2014 · 7,616 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe Optical Nonlinearity of Au and Ag Nanoparticle Prepared by the γ-Radiation MethodEsmaeil Shahriari, W. M.M. Yunus, Kazem Naghavi, Elias SaionProblem statement: The third order nonlinear optical properties of metal nanoparticles have been of interest in physical chemistry, medical diagnostics and optical devices. Gold colloidal nanoparticles are responsible for the brilliant reds seen in stained glass windows and silver particles are typically yellow. The purpose of the study was to determine the nonlinear refraction and absorption coefficient of the Au … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 9,541 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe Influence of pH on Nonlinear Refractive Index of Bromophenol BlueF.Z. Henari, K.G. CulliganProblem statement: Bromophenol blue is a pH indicator, a kind of chemical that changes colour when pH goes up or down over a narrow linear dynamic range of 3.0-4.6 pH units. Therefore a good approach must be taken to extend the linear response of the indicator in order to have simple calibration and precise measurements of PH sensors. The purpose … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 15,948 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsOptical Nonlinear Proreties and Optical Limiting Effect of Metanil YellowR. K. Rekha, A. RamalingamProblem statement: The third order nonlinear optical properties of organic polymers are used in high speed telecommunication, optical limiters and optical computers. The purpose of the study was to determine the third order nonlinear characteristics and optical limiting effect of the organic dye, metanil yellow in liquid and solid medium. Approach: The samples were prepared by dissolving the dye in … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 18 Jun 2009 · 7,719 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsMobility Management Technique for Real Time Traffic in 802.11 NetworksGurpal Singh, Ajay Pal Singh Atwal, B.S. SohisA practical mobility management technique aimed at reducing handoff latency to less than 10ms has been proposed and implemented in this paper. Handoff latency has been reduced by decoupling scanning from handoff execution process. This scheme has been implemented in the form of client side application with modifications to open source Madwifi new generation driver. Performance of this mobility management … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,779 accessesView PDF Cite

Case ReportOpen accessIn the keywordsBacterial Biofilm Persistence in Human Jawbone Following Tooth Extraction: Implications of Surgical Debridement and Resident Population-Shift for Oral ImplantsStephen Nelson, Honghua Hu et al.Intra-radicular infection theory assumes that when an infected tooth is extracted, the main source of infection is removed and any residual contaminating bacteria are killed by the immune response, then normal healing ensues. This study investigated whether bacteria and bacterial biofilms persisted in deep bone space following tooth extraction. The study was conducted on two adult male patients seeking dental … …Current Research in Dentistry, Vol. 14, Issue 1 · 31 May 2023 · 6,861 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsDental Color Matching: A Comparison between Visual and Digital Shade Selection Repeatability in the Anterior and Posterior Region: A Clinical StudyCarine Mounir Ziadeh, Pascale Habre, Lara Nasr, Helene HaddadThe clinical study aimed to evaluate the repeatability of the Intraoral Scanner (IOS) in terms of dental shade selection in comparison to the visual method and to find if the difference between these two methods is clinically acceptable. As well as to assess the impact of tooth position on the repeatability of the IOS in shade selection. Two experienced raters … …Current Research in Dentistry, Vol. 14, Issue 1 · 28 Apr 2023 · 7,048 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCharacteristics of Cut Head Hair: An Evidence in Criminal InvestigationsPol. Maj. Satina Polyiam, Pol. Lt. Sasithorn Boonmapa, Wuttichai Phae-Ngam, Pichet LimsuwanOne hot news occurred in Thailand one year ago was a 3-year-old girl was murdered and only a number of hair strands were found near her body and likely cut by a knife.
