Research ArticleOpen accessIn the abstractExperimental Study of Composite Beams Made of Steel Tubes Filled with Concrete under the Confinement Effect of U-Links and Stud-PlateMoayyad Al-Nasra, Madiha Ammari, Taher Abu-Lebdeh, Abdelqader NajmiConcrete strength improved substantially when lateral confinement stresses are provided. This effect has been exploited in this study in composite beams at the concrete compression zone. New type of confinement is used in this research. The confinement of concrete in the compression zone is accomplished by providing U-links and stud-plate systems. The U-links are steel bars in the shape of … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 7,265 accessesView PDFCite
EditorialOpen accessIn the abstractBig Data and Parkinson’s Disease - from Understanding of Disease to Personalised MedicineYen F. Tai, Nicola PaveseThe advancement of information technology in recent years has generated a huge amount of datasets in all areas of scientific research. This has led to new opportunities to harness the 'Big Data' to improve our understanding of diseases - from investigating disease mechanisms to monitoring treatment responses. The Big Data approach is a data-driven and often hypothesis-free, way of studying … …Neuroscience International, Vol. 7, Issue 1 · 27 Jul 2016 · 7,761 accessesView PDFCite
Research ArticleOpen accessIn the abstractModelling and Analysis of Voltage Mode Controlled Luo ConverterDivya Navamani Jayachandran, Vijayakumar Krishnaswamy, Lavanya Anbazhagan, Karthikeyan DhandapaniThis paper presents the analysis of open loop power stage dynamics relevant to voltage mode control for elementary Luo DC-DC converter for certain specific applications like Hybrid Electric Vehicles, fuel cell vehicles. A comparative analysis is carried out on positive output super lift series of converters to evaluate voltage gain, output voltage ripple, stresses on the switches and efficiency. The … …American Journal of Applied Sciences, Vol. 12, Issue 10 · 7 Nov 2015 · 7,102 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpread Foundations on Rigid Inclusions Subjected to Complex Loading: Comparison of 3D Numerical and Simplified Analytical ModellingDaniel Dias, Bruno SimonThis paper relates results of a large number of 3D numerical models of a single spread footing over a soil reinforced by four rigid inclusions and submitted to a large set of complex loading. This numerical study using the FLAC 3D software was done under funding of the ASIRI research project in an aim to support appropriate guidelines for design … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 12 Sep 2015 · 6,850 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Fungal Communities in Limed and Unlimed Lands Contaminated with Metals: Phospholipid Fatty Acid (PLFA) Analysis and Soil RespirationKassandre Goupil, Kabwe K. Nkongolo, Sabah NasserullaNorthern Ontario (Canada) especially the Greater Sudbury region is highly known for its nickel, copper and other metal deposits. The mining, roasting and smelting of these elements have caused disastrous effects on the vegetation and overall environment. Dolomitic lime which contains calcium and magnesium carbonate was applied to soils from 1980 to 1995 at different locations across Northern Ontario. The … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 2 · 26 May 2015 · 8,100 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimplified Analysis of the Lining Behavior During Earthquakes in Deep Rock TunnelsPierpaolo OresteThe sizing of the lining of a tunnel requires to consider not only the static loads transmitted from the surrounding rock, but also the effects of earthquakes on the stresses and strains of the lining. The detailed evaluation of the interaction earthquake-lining using numerical methods typically requires very long calculation time and can be limited to the verification of the … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 4 May 2015 · 6,905 accessesView PDFCite
Research ArticleOpen accessIn the abstractField Evaluation of Sugarcane Orange Rust for First Clonal Stage of the CP Cultivar Development ProgramDuli Zhao, R. Wayne Davidson, Miguel Baltazar, Jack C. ComstockConsistent development of high-yielding sugarcane (a complex hybrid of Saccharum spp.) cultivars with resistance or tolerance to biotic and abiotic stresses is critical to commercial sugarcane production. Currently, orange rust (caused by Puccinia kuehnii E.J. Butler) is a big challenge for the sugarcane production in Florida, USA. A better understanding of sugarcane genotypic variability in response to orange rust disease … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 1 · 27 Jan 2015 · 7,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethodology to Asses Internet Protocol Connection Availability: A Prerequisite For Feasible Video Stream Through Content Delivery NetworksVitor Chaves de Oliveira, Gunnar Bedicks Junior, Cristiano AkamineRecent events have shown that content delivery networks as well as Broadband Providers are failing to provide a continuous service, especially on live video stream transmissions for numerous customers. This study aims to present a Methodology to uninterruptedly measure uplink-downlink of a given IP connection. Based on an open-source assemblage of development and data storage platforms it was programmed a … …Journal of Computer Science, Vol. 11, Issue 2 · 2 Oct 2014 · 6,760 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE ADVERSE EFFECT OF STEEL PARTICLE CONTAMINANTS ON FATIGUE LIFE OF GREASE LUBRICATED BALL BEARINGSA. Stathis, Th. Costopoulos, D. Koulocheris, K. RaptisThe rating life of ball bearings is reduced when hard particle contaminants are present in the lubricant. Usually, this life reduction is taken into account in the calculation of modified rating life by using the contamination factor through a general characterization of the lubrication conditions. However, the impact of contaminant’s variables such as size, hardness and concentration level has to … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 14 Jul 2014 · 6,995 accessesView PDFCite
