Research ArticleOpen accessEvery word in the titleThe Evaluation of the Groundwater Influence on the Stress and Strain Behavior around a Tunnel by Analytical MethodsPierpaolo OresteThe presence of an aquifer in the soil causes a change in a relevant way of the stability conditions of a tunnel. The flow of water in the pores, in fact, modifies the stress and strain state of the soil and causes an increase in the thickness of the plastic zone. As a result the loads transmitted on the lining … …American Journal of Applied Sciences, Vol. 12, Issue 10 · 30 Oct 2015 · 6,459 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn Wing Tip Flow Around a Low Aspect Ratio Wing at Low Flight Speeds Using OpenFOAM® and Parallel ProcessingNikolaos Konstantinos Lampropoulos, Ioannis Eleftherios SarrisIn the present study, the effect of the wing tip geometry on the aerodynamic performance of a swept-back wing at moderate Reynolds numbers is investigated through numerical simulation and parallel processing. The aim is the identification of streamlines around the wing and subsequently the formation of the wing tip vortex. Due to the purely three-dimensional character of the flow, the … …Journal of Aircraft and Spacecraft Technology, Vol. 9, Issue 1 · 31 Jan 2025 · 9,538 accessesView PDFCite
Research ArticleOpen accessEvery word in the title2D Kinematic Quantification of Soil Particles around Growing Plant Root based on Optical MechanicsWenbin Wu, Jian ZhaoThe quantitative kinematic description of the surrounding soil particles during root growth is a technical challenge and biologically important. In this study, a two-dimensional camera-based imaging system was used to observe micro scale interactions between plant roots and soil particles. Maize root tip was imaged during ingress into the soils. This produced a series of two-dimensional images that represent temporal … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 21 Oct 2020 · 6,411 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSulfur Dioxide (SO2) and Heavy Metals Accumulation in Soils around Oil Refineries: Case Study from Three Southern Oil Refineries in the State of KuwaitLaila S. Gharib, Mohammad Al SarawiGeochemical and statistical analysis of Sulfur dioxide, Total Organic Carbon (TOC) and heavy metal pollutants (Pb, Cd, Zn, Cu, Ni, Fe, Mn, Cr and V) was conducted to soil samples around major oil refineries (Mina Ahmadi, Mina Abdullah and Shuaiba), industries and scanty residential areas in Al-Ahmadi governorate at the southern region of the State of Kuwait. High level of … …American Journal of Environmental Sciences, Vol. 14, Issue 1 · 8 Mar 2018 · 8,880 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDiscrete Vortex Prediction of Flow around Two Cylinders in Side by Side using Simple Grid SystemWisnu WardhanaModelling of flows around two cylinders in side by side arrangement using a simple overlapping grid system is carried out. The use of such grid system is intended to give a considerable reduction in terms of the CPU time, especially during the calculation of the vortex velocity. It has been shown that this method is not only time efficient, but … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 17 Jun 2017 · 8,133 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMonstrous Hazards Produced by High Radioactivity Levels Around Assiut Thermal Power PlantHany El-Gamal, Mohamed El-Azab Farid, Abdulla Ibrahim Abdel Mageed et al.The natural radioactivity level of heavy oil, ash and soil samples around Assiut Thermal Power Plant (ATPP) in Egypt was determined using gamma ray spectrometry. The average concentrations of 226Ra, 232Th and 40K in fly ash were found to be 2307±143, 1281±80 and 1218±129 Bq kg-1, respectively, while the corresponding values in soil samples were 2670±107, 1401±78 and 1495±100 Bq … …American Journal of Environmental Sciences, Vol. 9, Issue 5 · 17 Sep 2013 · 6,967 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleNumerical Study of Airflow around Vehicle A-pillar Region and Windnoise Generation PredictionM. H. Shojaefard, K. Goudarzi, H. FotouhiFlow separation and reattachment around the vehicle A-pillar region dictates strong pressure fluctuations on the side window surfaces and can also lead to generate aerodynamic noise. The objective of this work is to investigate qualitative flow visualization of airflow behaviour around vehicle A-pillar and its potential to generate windnoise in this region. By means of Computational Fluid Dynamic (CFD) under … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,335 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBoundary Shear Stress around Bridge PiersMirali MohammadiThis research presents the measurement of boundary shear stress around the base of some elliptical shaped bridge piers using Preston tube technique.
