Research ArticleOpen accessIn the abstractEvaluating the Effect of Soil Particle Characterization on Internal Friction AngleArezou Rasti, Hamid Ranjkesh Adarmanabadi, Maria Pineda, Jesse ReinikainenOne of the critical design parameters used in evaluating soil structure is the friction angle, derived from Mohr's Circle failure criterion. The soil friction angle is an engineering parameter estimated in the laboratory to quantify the soil shear strength in geotechnical applications. This paper indicates an experimental study investigating the impact of particle size on different sandy soils shear strength … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 21 Feb 2021 · 8,890 accessesView PDFCite
InvestigationOpen accessIn the abstractChanges in the Composition and Properties of Meadow Solonchaks of the Ili Alatau Foothill Plain in the Republic of Kazakhstan during a Long Postmeliorative PeriodZhainagul Yertayeva, Saginbay Kaldybaev, Aigul Kaiyrbekovna BeketovaThe optimal depth of the groundwater table and the water-salt regime is of importance in the postmeliorative period. The scope of these studies is to provide scientifically grounded assessment of previously reclaimed soils (water irrigation with a total norm of 5000 m3/ha under conditions of deep horizontal drainage, 1986-1989) in the postmeliorative period of 2015-2016 and to develop parameters for … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 14 Oct 2017 · 7,265 accessesView PDFCite
Research ArticleOpen accessIn the abstractCavern Design Philosophy under High Stress Rock Condition a Case Study in Sri LankaBahram SalehiFor stabilizing of rock cavern stress condition and orientation, rock properties and cavern geometry have determinant effects. Numerical and analytical study and knowledge about self-support arching can assist to designer in appropriate understanding of cavern and ground interaction. The comparative studies by E. Hoek, showed that the mushroom shaped cavern was not an acceptable design because of high value stress … …American Journal of Applied Sciences, Vol. 14, Issue 3 · 21 Mar 2017 · 7,978 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetection of tet Gene in Multidrug-Resistant Salmonella spp. Isolates from Layers and Broiler BreedersAgustin Indrawati, Leila Nur Azizah, I Wayan Teguh Wibawan et al.The present study was conducted with the following aims: (i) To detect the multidrug-resistant Salmonella spp. isolates recovered from faeces, litter and drinking water in layers and broiler breeders’ farms and (ii) to carried out the detection of the tet gene. A total of 21 Salmonella isolates were subjected to Polymerase Chain Reaction (PCR) assay to determine the presence of … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 2 · 17 Jun 2020 · 7,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmploying Electromagnetic Induction Technique for the Assessment of Soil CompactionKhalid A. Al-GaadiAn experiment on a sandy soil field was conducted to investigate the potential of determining soil compaction from apparent soil Electrical Conductivity (ECa) measured by Electromagnetic Induction (EMI) technique. A soil conductivity meter (EM38) was used to measure ECa under four soil Moisture Contents (MC) (4.965.336.94 and 8.0%) and a range of Soil Compaction (SC) levels (on the average, from … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 7 Nov 2012 · 8,253 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of a Heavy Duty Chisel Plow at Various Tillage Depth and Forward SpeedsS. A. Al-Suhaibani, A.E. GhalyProblem statement: Tillage is a process of creating a desirable soil condition for seed germination and growth. The tillage of soil is considered to be one of the biggest farm operations as the tillage operation requires the most energy on the farm. Manufacturers of tillage implements tend to overdesign their products due to a lack of the proper testing and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 8,313 accessesView PDFCite

Research ArticleOpen accessIn the abstractEffects of Novel Disk-type Furrow Opener Used in No-Tillage System on Micro Environment of SeedE. Seidi, S.H. Abdollahpour, A. Javadi, M. MoghaddamProblem Statement: Offset Double-Disk Opener (DDO) is a popular furrow opener in conservation tillage. It has some limitations such as negative suction to penetrate in the soil, hair pinning and mixing seed and fertilizer in the slot. Because of importance of separation of seed and fertilizer in the slot, by adding two horizontal mini disks to DDO a modified opener … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 9,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarthquake Resistant Design of Reinforced Soil Structures Using Pseudo Static MethodB. Munwar Basha, G.L. Sivakumar BabuProblem statement: This study presented a method to evaluate the internal stability of reinforced soil structures against tension and pullout modes of failure using pseudo-static method for earthquake conditions. Approach: Using limit equilibrium method and assuming the failure surface to be logarithmic spiral, analysis was conducted to maintain internal stability against both tensile and pullout failure of the reinforcements.
