Research ArticleOpen accessIn the abstractExperimental Investigation Of Polymeric Compound Cross Section SpringsMayas Al-Mahasne, Tareq A. Abu ShreehahThis paper presents an experimental investigation of the characteristic of the compound cross section springs on models made from polymeric materials (organic glass). Two constructive variants of the compound spring sections were specified with the help of criteria of similarity. The criterion of similarity of natural and model springs was determined by the simulation method at particular spring deflection. The … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 6,758 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIdentification, Characterization and Quantification of Elastomeric/Plastomeric Waste for Sustainable Waste MinimizationKajal Yadav, Sangita, A. ChandraThe present study focuses on the importance of characterization of waste/post consumer polymers. In recent years sophisticated instrumental techniques played an important role in identification and characterization of polymers. Advances in computer techniques have been combined with analytical instruments to give analytical speed, resolution and minimal sample requirements unimagined a few years ago. The present study deals with the development … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,058 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPhysical and Geometrical Effects on the Vibratory Pattern of a Pipe Carrying Fluid FlowDahmane Mouloud, Samir Zahaf, Mawhoub Soubih et al.In this research, the first natural frequencies and critical velocities of a fluid flow-conveying pipe are obtained with finite element method. By discretizing the structure wall and fluid flow, starting from beam type with two degrees of freedom per node. We determine the equation of motion from the fluid-structure coupling using Lagrange energy principle. Parameters frequencies and critical velocity of … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 22 Oct 2020 · 11,399 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordIsolation and Physical Characterization of Hydrophobin-Like Proteins (HLP) from Aerial Conidia of Metarhizium Anisopliae Var. AnisopliaeD. S.B. Kiong, Choon Fah J. Bong, P. J.H. KingThe aim of this study was to isolate and physically characterized Hyrophobin-Like Proteins (HLP) from the aerial conidia of two local isolates of Metarhizium anisopliae var. anisopliae, namely, TA and LR2. The protein samples were isolated based on their insolubility in hot Sodium Dodecyl Sulfate (SDS). The SDS-insoluble proteins were then purified in cold 98% formic acid and performic acid. … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 2 · 29 Jan 2015 · 7,778 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSIMULTANEOUS OPTIMISATION OF DRYING PARAMETERS OF CERAMIC BODIESSalah Mahmoudi, Ezzeddine Srasra, Fouad ZargouniThis study deals with the mineralogical, physico-chemical and geotechnical analyses of representative Aptian clays in the north-east of Tunisia. X-ray diffraction reveals a predominance of illite (50-60 wt.%) associated to kaolinite and interstratified illite/smectite. The accessory minerals detected in raw materials are quartz, calcite and Na-feldspar. The average amounts of silica, alumina and alkalis are 52, 20 and 3.5 wt.%, … …Current Research in Geoscience, Vol. 4, Issue 1 · 1 Jul 2014 · 6,996 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordApplying the Holistic Approach to the Physical Sciences and Engineering SystemsJoseph Z. Ben-AsherThe holistic approach is applied to several examples from the field of physics, engineering and systems engineering and its benefits are demonstrated. In all examples a holistic picture is used and studied while ignoring the various details of the discussed problems. Optimal control and optimal estimation approachs are used in the engineering examples. The results show that the holistic approach … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 28 Aug 2013 · 6,915 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPhysical Composition, Nutrients and Contaminants of Typical Waste Dumping SitesH. Meuser, K. S. Grewal, R. Anlauf et al.Problem statement: The composition of wastes is quite variable depending upon the generating source and mode of collection. Most of the material from the domestic activities will be organic in nature and contains essential plant nutrients, whereas the dumping material of commercial and industrial wastes usually contains appreciable amounts of heavy and potentially toxic metals and organic pollutants. Approach: Objective … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,761 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDynamical Properties Analysis of Frictional Winding Mechanism with Bobbin Elastic SupportMohammed A. Alnawafleh, Faisal M. Al-GhathianA mathematical model of the Frictional Winding Mechanism (FWM) with bobbin elastic supports for a search of optimal structural and physical parameters for developing new and updating existing FWMs has been carried out. The model was derived from bobbin equipped with pendulum suspension for forming cylinder shaped packages. In the derivation method it was considered that the model corresponds the … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,886 accessesView PDF Cite
