Mathematical Model to Monitor the Transport of Bordetella Influenced by Heterogeneous Porosity in Homogeneous Gravel Depositions
Abstract: The study monitors the transport process of Bordetella in grave depositions. The study expresses the rates of depositions under fluctuation of micronutrients in the litho structures where predominant grave formation was observed. Such conditions explain the simulation values as they predominantly fluctuate with heterogeneous concentrations in deltaic formation. The study has explained the heterogeneity of deposited porosity and observed that it could not pressurize the behaviour of Bordetella transport in …

A Review on Stabilization of Expansive Soil Using Different Methods
Abstract: Expansive soils are difficult soils for construction purposes because of their cyclic swell/shrink behavior. These soils undergo significant expansion when subjected to an increase in water content or shrink under evaporation condition (when water out). Bulging soils can be improved in several ways. Either by adding materials such as cement, lime, sand and adding river mixture soil. or these soils treated with chemical additives. When added to expansive soils in …

Bearing Capacity of Double Box Shaped Skirted Footings on Sand
Abstract: The double-box-shaped footing with and without skirt and sand-resting pressure settlement behavior was discussed in this paper. Different parameters are normalised skirt depth (0.25 to 1.5), relative sand density (30 to 60 percent) and sand footing interface state (partially rough and rough). Results of this study showed that a general and local shear failure was observed at a relative density of 50 percent and 60 percent, and 30 percent and …

Small-Scale Model Study on the Load-Deflection Characteristics of Single Piles under Static Lateral Load
Abstract: The capacity of a certain mathematical model to mimic a behavior occurring on a larger scale often concerns engineers. To evaluate a particular structure's safety factor, model uncertainty is an important consideration. Piles have been widely used to support axial and lateral loads for a wide range of structures, including high-rise buildings, transmission towers, power plants, offshore structures, highway and railway structures. Many transmission towers, high-rise buildings, highway and railway …
