Research ArticleOpen accessEvery word in the titleDose Response and Optical Properties of Dyed Poly Vinyl Alcohol-Trichloroacetic Acid Polymeric Blends Irradiated with Gamma-RaysSusilawati, Aris DoyanProblem statement: The effects of gamma irradiation on optical properties of cresol-red dyed Poly Vinyl Alcohol (PVA) blended with Trichloroacetic Acid (TCA) for possible use in dosimetry and measurement of radiation dose in gamma rays have been studied using both Raman spectroscopy and UV-Visible spectrophotometer method. Approach: The dosimeters are composed of Poly Vinyl Alcohol (PVA), Trichloroacetic Acid (TCA) at … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,088 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStudy of Porous Nanoflake ZnO for Dye-Sensitized Solar Cell ApplicationH. Abdullah, N. P. Ariyanto, S. Shaari et al.Problem statement: Nano-scale porous ZnO with high surface area have been studied to enhance physicochemical and electrochemical properties of certain optoelectronic devices applications. Approach: ZnO porous structure consists of flake-shape particles was synthesized through pyrolitic reaction of hydrozincite as Chemical Bath Deposition (CBD) product. Flake-like particle perpendicularly lied on substrate was obtained after 24 hours deposition. After calcinations, cavities on … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,377 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBehavioral, Physiological and Biochemical Hormetic Responses to the Autoxidizable Dye Methylene BlueAleksandra K. Bruchey, F. Gonzalez-LimaThe goals of this review were to identify methylene blue (MB) as a compound that follows hormetic behavior for a wide range of effects and to address the question of what is unique about MB that could account for its wide applicability and hormetic behavior as a drug. The MB hormetic doseresponse relationship is exemplified by an increase in various … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 15,044 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleChanges in Leaf Characteristics with Tree Age in Dryobalanops beccarii Dyer in a Restored Forest of Sarawak, MalaysiaEmilla Yastari LAPOK, ONG Kian Huat, John Keen CHUBO, Patricia KING Jie HungStudy on leaf properties of an endangered dipterocarp tree species, Dryobalanops beccarii, was conducted in a restored forest. The study focused on the morphology, nutrient concentration and gas exchange in well-developed leaves of D. beccarii at different ontogenetic phases. The hypothesis tested that leaf physiological and morphological changes are related to the nutrient concentration level of D. beccarii leaves in … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 25 Sep 2017 · 7,542 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDecolorization of Mordant Orange-1 by Marinobacter algicola MO-17R. S. Shertate, Prakash ThoratProblem statement: The textile industries use different types of dyes in their processing units which are liberated in natural marine water bodies. This release of dyes in turn affect the marine flora and fauna very adversely. Approach: The release of textile dyes into the environment is a matter of concern due to the toxicity, mutagenicity, carcinogenicity and xenobiotic nature. Hence, … …OnLine Journal of Biological Sciences, Vol. 12, Issue 1 · 25 Feb 2012 · 7,513 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStudy on Optical Constants and Refractive Index Dispersion of Neutral red Doped Polymer FilmHussain A. BadranProblem statement: The some optical constants polymer thin film with red dye 3-amino-7-dimethylamino-2-methyl phenazine (NR) as the guest material and Polyvinylpyrrolidone (PVP) as the host material were prepared by adulteration and spin-coating methods. Approach: The values of some important parameters (refractive index n, extinction coefficient K and dielectric constant ε∞) of polymer thin film are determined from these spectra. Results: … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 8,919 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInduction of Caspase-dependant Apoptosis by Enterovirus 70 in Human Lens Epithelial SRA01/04 CellsDequan Chen, Chris Duggan, Donald E. Texada et al.Enterovirus 70 (EV70), an etiological agent of acute hemorrhagic conjunctivitis (AHC), induces apoptosis in human Chang’s conjunctival (HCC) cells. EV70 is also able to infect and replicate in some other human cells such as human lens epithelial SRA01/04 cells and U937 cells. EV70 infection was found to induce apoptosis in SRA01/04 cells. During EV70-induced apoptosis of SRA01/04 cells, the expression … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 6,636 accessesView PDFCite
