EditorialOpen accessIn the abstractVolume 3: SGAMR is Always on Track!Chiara Bedon, Mario D’Aniello, Flavio StochinoThe year 2019 represents a new growing step for SGAMR, that starts to publish “continuously” all the accepted papers, once they are subjected to positive, blinded peer-review process. This is a further effort to improve the service for the contributors and for the readers, given that the efficiency of the journal to share knowledge can be maximized. Hänig et al. … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 28 Aug 2020 · 5,713 accessesView PDFCite
Case ReportOpen accessIn the abstractRetroperitoneal Hydatid Cyst Masquerading as a Retroperitoneal Cystic TumorK. Hemanth Kumar, Anish Choudhary, Amaresh Aruni, N.V.K.N. KarthikHydatid disease is an endemic disease, with canines the primary host and humans the intermediate host. Liver, spleen and lungs are most common involved organs, but it can involve any organ. Retroperitoneal hydatid cyst are categorised into two types, primary and secondary. Primary retroperitoneal hydatid cyst is rare disease, with most of the cases diagnosed intra-operatively, hence pre-operative high index … …American Journal of Infectious Diseases, Vol. 15, Issue 3 · 29 Aug 2019 · 7,269 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntimicrobial Activities of Unconventional Compounds against Some Bacteria Associated with Skin Infections in Humans, Sheep and GoatsIman Shabana, Amira El-AdlyBacterial skin infections are a common problem encountered in clinical practice and causing great economic losses for sheep and goats producers. Increasing multidrug resistance of pathogens paves the way for reconsidering alternative medicine. The present study was carried out to explore the antibacterial activities of different volumes; 5, 25, 50 and 100 µL of gold nanoparticles (NPS) and the aqueous … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 11 Jan 2016 · 8,029 accessesView PDFCite
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

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
