abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...

In order for the promise of terahertz (THz) wireless communications to become a reality, many new devices need to be developed, such as those for routing THz waves. We demonstrate a power splitting router based on a parallel-plate waveguide (PPWG) T-junction excited by the TE1 waveguide mode. By integrating a small triangular septum into the waveguide plate, we are able to direct the THz light ...

An unsteady, two-dimensional, hydromagnetic, laminar mixed convective boundary-layer flow of an incompressible, Newtonian, electrically-conducting and radiating fluid along a semi-infinite vertical permeable moving plate with heat and mass transfer is analyzed, by taking into account the effect of viscous dissipation. The plate moves with a constant velocity in the direction of fluid flow while...

Classical discharge theory (Townsend and streamer theory) has limitations in explaining nanosecond pulsed gas discharge. In recent years, the research on based high-energy runaway electrons attracted extensive attention. But so far, there have been few studies of generation mechanism atmospheric-pressure-air plate-to-plate discharge, which seriously hinders application development pulse plasma....

We study the approximation of the Reissner-Mindlin plate using the p/hp version of the finite element method (FEM). Our goal is to identify a method that: (i) is free of shear locking, (ii) approximates the boundary layer independently of the thickness of the plate and (iii) converges exponentially with respect to the number of degrees of freedom. We will consider both standard and reduced cons...

The objectives of the present study are investigate the unsteady two-dimensional laminar flow of a viscous dissipative micropolar fluid past a semi-infinite, vertical porous plate moving steadily and subjected to a thermal radiation and mass transfer. The plate moves with constant velocity in the longitudinal direction and free stream velocity follows an exponentially small perturbation law. Th...

in this research, the accelerated ripening of the kabkab dates from khalal to tamr using nacl and acetic acid solutions was studied. fruits at khalal stage were harvested and washed with distilled water before being treated with ripening inducers: 1. nacl solutions, 2. acetic acid solutions and 3. aqueous solution of nacl (1%) and acetic acid. moisture, ph, colour, brix and textural firmness of...

Two models, a simple cooling model and the plate model, have been advanced to account for the variation in depth and heat flow with increasing age of the ocean floor. The simple cooling model predicts a linear relation between depth and t •, and heat flow and l/t«, where t is the •ge of the ocean floor. We show that the same t • dependence is implicit in the solutions for the plate model for su...

A homogeneous, isotropic plate occupies the region 0 x1 ∞, |x2| a, |x3| h, where the semi-thickness h = h(x2). The ratio h(x2)/a is supposed to be everywhere sufficiently small so that the classical theory of bending of thin plates (of non-uniform thickness) applies. The short end of the plate at x1 = 0 is clamped while the long sides are free. This cantilever plate is now loaded at x1 = +∞ by ...
