Research ArticleOpen accessIn the abstractSorption Extraction of Noble and Non-Ferrous Metals from Process Leaching SolutionsBagdaulet Kenzhalyevich Kenzhaliyev, Renata Ramilevna Iskhakova, Zamzagul Duisenovna DosymbayevaIn view of the annual increase in ore processing output for low grade or refractory gold-bearing ores, as well as recoverable raw materials, stricter requirements for completeness of gold extraction and environmental safety, the interest is rising in possible alternatives to substitute the cyanide process used in gold mining practice. One of such alternatives is to convert metals into solutions … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 18 Nov 2015 · 7,053 accessesView PDFCite
Research ArticleOpen accessIn the abstractβ1,3-GLUCAN ANTICANCER EFFICACIES AND SYNERGIES: A REVIEWStory Jenny, Vetvicka Vaclav, Angove Michaelβ1,3-glucans from fungi, cereals, seaweeds and bacteria have been shown to possess favourable biological and anti-carcinogenic activities including upregulation of phagocytosis, cytokine production enhancement, superoxide and nitrite production; antibody secretion and stimulation of signalling pathways associated with proto-oncogene expression. However, human dietary supplements containing β1,3-glucans vary in efficacy due to glucan source, the lifecycle stage of the source at extraction, … …American Journal of Immunology, Vol. 10, Issue 3 · 3 Sep 2014 · 8,765 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptical Properties of Crosslinked Chitosan Thin Film with Glutaraldehyde Using Surface Plasmon Resonance TechniqueYap Wing Fen, W. Mahmood Mat Yunus, Mohd Maarof Moksin et al.Problem statement: The aim of this research is to study the optical properties of crosslinked chitosan thin film with glutaraldehyde using Surface Plasmon Resonance (SPR) technique. Approach: The crosslinked chitosan is synthesized by homogeneous reaction of medium molecular weight chitosan in aqueous acetic acid solution with glutaraldehyde as crosslinking agent. Four different amount of chitosan, i.e., 0.40, 0.50, 0.60 and … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 28 Jan 2011 · 9,633 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe 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 · 9,545 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling and Interpretation of PbPc Gas Sensor ArrayNidal F. Shilbayeh, Mahmoud Z. IskandaraniThe voltage/current characteristics and the effect of NO2 gas on the electrical conductivity of a PbPc gas sensor array is investigated. The gas sensor is manufactured using vacuum deposition of gold electrodes on sapphire substrate with the lead-phathalocyanine vacuum sublimed on the top of the gold electrodes. Two versions of the PbPc gas sensor array are investigated. The tested types … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Jun 2006 · 6,791 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Analysis of Various Diagnostic Methods for Trichomonas Vaginalis Infection in Trinidad and TobagoAruna Kumari Divakaruni, Bisram Mahabir, FA Orrett et al.Trichomonas vaginalis infection is a common sexually transmitted infection in the reproductive age group, which may lead to complications. Wet mount examination is the most common test for diagnosis, but it has low sensitivity. Fluorescent antibody staining can be used for diagnosis, but it is expensive and requires special microscopic facility. Culture is considered as the gold standard, but it … …American Journal of Infectious Diseases, Vol. 14, Issue 2 · 6 Oct 2018 · 8,064 accessesView PDFCite
Review ArticleOpen accessIn the abstractNew Researches Examines the Wing Shapes to Reduce Vortex and WakeNicolae Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuIt is common to see clouds in the form of the sky, known as contrails, which are behind the engines of a reaction plan. What is not always visible is a wind whirl that comes out of the top of each wing - like two small horizontal tornadoes - leaving behind a turbulent awakening behind the vehicle. Awakening is a … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 19 Jun 2018 · 7,422 accessesView PDFCite
Research ArticleOpen accessIn the abstractNamed Entity Recognition for Kannada using Gazetteers list with Conditional Random FieldsK. P. Pallavi, L. Sobha, M. M. RamyaNamed Entities (NEs) that exist in the sentences are essential to build Natural Language Processing (NLP) applications for Information Extraction (IE) from large corpora. However, generating a large corpus is challenging for resource poor languages, such as Kannada. Further, there is no annotated corpus available online. The challenges faced in annotating NEs with pre-defined classes are: It is morphologically joined … …Journal of Computer Science, Vol. 14, Issue 5 · 24 Feb 2018 · 8,278 accessesView PDFCite
