Review on Metal Bellows Used in Expansion Joints
Abstract: Metallic bellows are manufacturing expansion joints commonly used in aerospace, chemical plants, power system, heat exchangers, automotive vehicle parts, piping system, petrochemical plant, refineries, etc., which are subjected to high temperature, pressure and corrosive environment. Bellows are special structures that require high strength as well as good flexibility. Most industrial piping system often suffer excessive deformation, displacement, heat expansion, vibration, and other causes which are responsible for the failure. During …

Status of Surfactant-Polymer Flooding
Abstract: Abstract Surfactant-polymer (SP) flooding emerged from the principle that good sweep efficiency and displacement efficiency result in good oil recovery. Its research and development was shifted to alkaline-surfactant-polymer (ASP) because higher oil recovery can be achieved from the latter. Apparently, some research-development focus is coming back to SP, because ASP has problems in practical applications, e.g., scaling and emulsion. This paper provides the status of surfactant-polymer flooding technology. It covers …

Response Spectrum Analysis of RC Buildings Constructed on Plain and Sloping Ground with Different Configuration of Shear Walls
Abstract: Abstract Buildings constructed on slopes are different from those in plains. They may be irregular and unsymmetrical in horizontal and vertical planes, and torsionally coupled. Hence, they are susceptible to severe damage when affected by earthquake ground motion. We can’t avoid the future earthquakes but the preparedness and safe building construction practices for earthquakes can certainly reduces the extent of damage and loss of both property and life. Shear wall …

Design of Electrostatic RF Switch using COMSOL
Abstract: This paper presents the design, modeling, and measurements of radio frequency micro electromechanical systems (RF MEMS) switches. These models are rectangular, taper, and meandering beam structures. The characteristics of RF MEMS switches including displacement and natural frequency are studied. Rectangular, taper, and meandering structures are selected because these three structures display different geometrical shapes. Geometrical shapes are one of the important factors as far as the mechanical and electronic characteristics …

Thermal Stress Analysis of Cross-ply Laminated Plates using Refined Shear Deformation Theory
Abstract: A refined shear deformation theory is presented for laminated plates under thermal loading. The in-plane displacement field uses sinusoidal function in terms of thickness co-ordinate to include the shear deformation effect. Governing equations and boundary conditions of the theory are obtained using the principle of virtual work. Stresses and deflections of isotropic, orthotropic, symmetric and antisymmetric cross- ply laminated plates subjected to linear thermal loads are obtained. It is to …

Impact of invading fish on native species
Abstract: The term "alien species" refers to organisms that have been intentionally or unintentionally introduced outside of their natural range. These organisms have the ability to establish self-sustaining populations, spread beyond the initial point of introduction, and have a negative impact on the environment and the economy. Through crossbreeding with closely related native species, these fish with diverse genetic make-up cause the formation of a new group of organisms with different …
