Research ArticleOpen accessIn the abstractPreparation and Polishing Properties of Spherical Porous Silica AbrasiveHong Lei, Hu Li, Ping Liu, Ruling ChenProblem statement: Abrasive is one of key influencing factors on the polished surface quality in Chemical Mechanical Polishing (CMP). Solid abrasives in CMP slurries are easy to cause polishing scratches. It is well known that reducing the hardness of abrasives would improve the polished surface quality. Therefore, the change in structure or shape of the abrasives means a change in … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 9,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Investigation of Factors Influencing Design Team Attributes in Green BuildingsMohamed S. Elforgani, Ismail RahmatProblem statement: Buildings contribute significantly global environmental problems. Better design can minimize these impacts. Design Green Building (DGB) aims to reduce buildings' impact on the environment. However, the green design performance depends on design team attributes. In addition, the Governance System (GS) and Client Quality (CQ) as external factors have influence on Design Team Attributes (DTA) of green building. Approach: … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,962 accessesView PDFCite

Research ArticleOpen accessIn the abstractUncertainty Impact of the Effective Diffusion Coefficient on the Concrete Chemical DegradationA. BadaouiReinforced concrete is the construction material widely used in civil engineering. However, knowledge of its long-term performance and the uncertain impact of the environment on his behaviour make it difficult to accurate assessment of the durability of structures with time. When a structure is put into service, it is likely to damage, which origin can be physical, mechanical or chemical. … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 23 Jul 2015 · 7,758 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Influence of the Climatic Factors on the Decay of Marbles: an Experimental StudyPaola Marini, Rossana BellopedeStone decay is affected by the influence of climatic factors. In particular marble degradation, that could be expressed by decohesion and /or bowing, is mainly due to the action of temperature and water (rains and relative humidity). In this work non destructive and destructive tests have been performed to evaluate the decay of marble slabs subjected both to natural exposition … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,123 accessesView PDFCite

The angle of repose of paddy soil is 53.00° tested by the lateral wall collapse method. Eleven parameters are used to establish EDEM simulation model with … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 16 Dec 2020 · 6,377 accessesView PDFCite
Research ArticleOpen accessIn the abstractSTOCHASTIC REPAIR AND REPLACEMENT OF A STANDBY SYSTEMMohammed A. HajeehMechanical systems deteriorate over time and do not perform according to their intended functions and eventually fail due to the failure of one or more their components or units. Failed components are either repaired or replaced depending of several factors such as cost, criticality, or reliability. Repair is perfect, minimal, or imperfect. This study assesses the performance of a standby … …Journal of Mathematics and Statistics, Vol. 10, Issue 3 · 9 Oct 2014 · 6,570 accessesView PDFCite
Research ArticleOpen accessIn the abstractPORE-PRESSURE PREDICTION FROM SEIMIC DATA IN PARTS OF THE ONSHORE NIGER DELTA SEDIMENTARY BASINEmujakporue Omokenu GodwinPore pressure prediction in parts of the Onshore Niger Delta Sedimentary Basin using seismic reflection data has been carried out. The Bower’s technique of velocity-to-pore pressure transform was adopted. The seismic velocities were derived from the seismic data using layer cake velocity model and were later compared with the available sonic logs velocities obtained from the area. Parameters in the … …Physics International, Vol. 4, Issue 2 · 20 Mar 2014 · 7,437 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevention and Prophylaxis of Tick Bites and Tick-Borne Related DiseasesLara Garcia-Alvarez, Ana Maria Palomar, Jose Antonio OteoTicks are obligate haematophagous arthropods present all over the world able to produce human diseases. Several factors have increased the abundance, circulation and distribution of the pathogens transmitted by ticks, contributing to the change in the vector-borne diseases epidemiology in the last years. This review collects the most important measures for the prevention and prophylaxis of tick-borne diseases.
