Research ArticleOpen accessIn the abstractBiochemical and Genetic Responses of Fungi to the Toxic Effect of Synthetic and Natural FungicidesMarÍa-Elena Báez-Flores, Rosalba Troncoso-Rojas, Martin-Ernesto Tiznado-HernándezThe objective of the present review is to analyze the molecular basis of fungicide resistance mechanism to both synthetic fungicides and the natural fungicides isothiocyanates. The review is focused mainly on Alternaria sp., but whenever available, similar studies in other fungi have been included. Fungal resistant strains to dicarboximide and phenylpyrrole fungicides have been found to contain mutations in one … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,122 accessesView PDFCite
Research ArticleOpen accessIn the abstractMapping QTLs Linked to Physio-Morphological and Plant Production Traits under Drought Stress in Rice (Oryza sativa L.) in the Target EnvironmentS. Michael Gomez, S. Satheesh Kumar, P. Jeyaprakash et al.Drought stress is a major constraint for rice (Oryza sativa L.) production and yield stability in rainfed ecosystems. Identifying genomic regions (QTLs) contributing in drought resistance will help to develop rice cultivars suitable for water-limiting environments through marker-assisted breeding. QTLs linked to physio-morphological and plant production traits under drought stress in the field were mapped by evaluating 177 F6 recombinant … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 14,482 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncreasing the Strength of Standard Involute Gear Teeth with Novel Circular Root Fillet DesignV. Spitas, Th. Costopoulos, C. SpitasIn this study the idea of spur gear teeth with circular instead of the standard trochoidal root fillet is introduced and investigated numerically using BEM. The strength of these new teeth is studied in comparison with the standard design by discretizing the tooth boundary using isoparametric Boundary Elements. In order to facilitate the analysis the teeth are treated as non-dimensional … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,592 accessesView PDFCite
Research ArticleOpen accessIn the abstractMetabolite Profiles of Arsenic Tolerant Plants Regenerated from Stem Calli of Andrographis paniculata (Burm.f.) Nees using HPLC and 1D 1H NMRJ. Vijayakumar, P. Ponmanickam, P. Samuel et al.In vitro culture provide a suitable condition for regeneration of arsenic tolerant plants from stem calli of Andrographis paniculata (Burm.f.) Nees. The regenerated plants could be valuable material applicable to soil remediation. In vitro culture of stem explants on MS basal salts, 3.0% sucrose, 0.8% agar medium fortified with various concentrations of As2O3 (0.0-9.0 µM) along with NAA (3.5 mg … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 27 Oct 2017 · 7,867 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Different Environments on Reinforcement Concrete CorrosionMohammed Thalji Awwad, Omar Asad AhmadThis research focuses on various forms of steel bar corrosion located in different environments and the factors affecting the corrosion process, both the external (surrounding environment around concrete elements) and the internal environment (concrete itself), as well as on the investigations and tests for this type of damage, in order to develop measurements and recommendations that will reduce harmful investment … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 15 Sep 2017 · 7,811 accessesView PDFCite
Research ArticleOpen accessIn the abstractFracture Initiation at the Zirconia/Veneer Interface-A Finite Element SimulationMirsayar M. M., A. T. SamaeiZirconia/veneer bilayered components are extensively used in dental restoration technology to improve resistance of tooth's surface from decay. The direction of the fracture propagation at the interface of zirconia and veneer is investigated in this study. Finite element analysis is performed on a bi-material four point bend specimen in different geometries and the fracture initiation angle is obtained using Maximum … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 8 Jun 2015 · 7,573 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating Effects of Application of Silica Fume to Reduce Asphalt Oxidative AgingNader Abutalib, Elham H. Fini, Sassan Aflaki, Taher M. Abu-LebdehThis paper investigates the feasibility of using silica fume to enhance the rheological properties of asphalt binder. It has been widely reported that asphalt binder oxidation is one of the phenomena that reduces the service life of asphalt pavement by negatively impacting its rheological properties. This in turn can lead to a more brittle pavement which is more prone to … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 22 Apr 2015 · 8,492 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdhesion of Probiotic Bacteria to Resistant Rice StarchGhalia Salem, Zaiton Hassan, Maryam AbubakrResistant starch as prebiotics can be combined with probiotics to increase their survival during processing of food products. In present study Lactic Acid Bacteria (LAB) which, isolated from (yoghurt, banana and human breast milk) were screened for their probiotic properties and evaluated for the adhesion properties to Rice Resistance Starch (RRS). 26% of the isolates (10/39) overcame the stress to … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 5 Apr 2013 · 6,751 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Behavior of Tyre Tread BlockK. Sridharan, R. SivaramakrishnanThe Tyre tread pattern is the arrangement of blocks, grooves and voids, sipes and channels designed into the tread to enhance its grip on the road. Tread is the uppermost part of any tyre which contact into the road and it has its own performance towards mileage, traction, low noise and heat built up properties. It would be meaningful to … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 28 Jul 2012 · 9,798 accessesView PDFCite
