Knowledge of flow pattern and flow pattern transitions is essential to the development of reliable predictive tools for pressure drop and heat transfer in two-phase micro-channel heat sinks. In the present study, experiments were conducted with adiabatic nitrogenwater two-phase flow in a rectangular micro-channel having a 0.40632.032 mm crosssection. Superficial velocities of nitrogen and water...

Finite Difference Time Domain (FDTD) is applied to study the characteristics of electromagnetic interference for power plane-battery management system (PP-BMS) enclosure, for modeling the coupling of an incident electromagnetic pulse (EMP) with a conducting wire through a BMS enclosure and aperture on it. Simulation and analysis are done by radius of the wires, incidence angles of EMP in the co...

Porokeratoses are uncommon hereditary or acquired keratinization disorders due to abnormal clones of keratinocytes in the epidermis. Porokeratoses have several clinical features which may occur simultaneously. A rare type is verrucous porokeratosis (VPK). Herein, we present a 47-year-old man with a 4-year history of perianal verrucous lesions and one year history of annular pruritic lesions on ...

In the present article, buckling analysis of functionally graded annular thin and moderately thick plates under mechanical and thermal loads is investigated. The equilibrium and stability equations of the plate are obtained based on both classical and first order shear deformation plate theories. By using an analytical method, the coupled stability equations are converted to independent equatio...

Hollow sections have been widely used for steel structures. Applications of High Strength Steel (HSS) on cold-formed hollow sections lead to thinner and lighter structures. This paper presents numerical investigations on the lateral-torsional buckling resistance of the cold-formed high strength steel rectangular hollow beam. Results from finite element analysis using Abaqus software are compare...

Objective: To investigate the cytomorphological and physico-chemical characteristics of Sida rhombifolia. Methods: Fresh leaves, stems and roots were studied for microscopical characters and dried powder of leaves, stems and roots were subjected to physico-chemical analysis using standard methods. Results: The detail microscopy of leaf revealed the presence of paracytic stomata, unicellular cov...

The ability to precisely trap, transport and manipulate micrometre-sized objects, including biological cells, DNA-coated microspheres and microorganisms, is very important in life science studies and biomedical applications. In this study, the acoustic radiation force in an ultrasonic standing wave field is used for micro-objects manipulation, a technique termed as acoustophoresis. Free surface...

The group generated by the kinematic dynamo operator in the space of continuous divergence-free sections of the tangent bundle of a smooth manifold is studied. As shown in previous work, if the underlying Eulerian flow is aperiodic, then the spectrum of this group is obtained from the spectrum of its generator by exponentiation, but this result does not hold for flows with an open set of period...

The paper reports a new method for three-dimensional observation of the location of focused particle streams along both the depth and width of the channel cross-section in spiral inertial microfluidic systems. The results confirm that particles are focused near the top and bottom walls of the microchannel cross-section, revealing clear insights on the focusing and separation mechanism. Based on...
