the effect of different juice extraction treatments on the qualitative properties of lime juice was investigated. samples were selected from jahromi lime variety and lime juice extracted by means of a screw type juice extraction device. the mechanical parameters of the helical juice extractor [screw velocity (270, 360 and 450 rpm), outlet pressure (minimum, medium vs. maximum)] and lime pretrea...

The present study examined the memory and speed of processing abilities associated with general giftedness (G) and excellence in mathematics (E). The research involved four groups of 16-18 years old participants varying in levels of G and E. 160 participants were tested on a battery of three memory tests and five speed of processing tests. Working-memory was found to be related to both G and E ...

in this work we solve the set of hydrodynamical equations for accretion disks in the spherical coordinates (r,θ,ϕ) to obtain the explicit structure along θ direction. we study a two-dimensional advective accretion disc in the presence of thermal conduction. we find self-similar solutions for an axisymmetric, rotating, steady, viscous-resistive disk. we show that the global structure of an advec...

A metric of non-negative sectional curvature on the direct product S2 × S2 of two two-spheres may be introduced as follows: take spheres (S2 i , gi), i = 1, 2 with rotationally symmetric metrics of non-negative curvature and consider the factor space of (S2, g1) × (S2, g2) × S1 by the action of the family of isometries Ĩτ (φ1, φ2) acting as the composition of a rotation of the first factor by a...

A retrospective study was carried out on 79 patients with a history of mold exposure, fatigue, and chronic rhinosinusitis (CRS) to determine whether there is a causal relationship between fungal exposure and chronic sinusitis, fatigue, and anterior hypopituitarism, especially growth hormone deficiency (GHD). Of the patients, 94% had a history of CRS, endoscopically and/or computed tomography (C...

Fluid flow in the mold region of the continuous slab caster at Panzhihua Steel is investigated with 0.6-scale water model experiments, industrial measurements, and numerical simulations. In the water model, multiphase fluid flow in the submerged entry nozzle (SEN) and the mold with gas injection is investigated. Top surface level fluctuations, pressure at the jet impingement point, and the flow...

In this work, a fast radix-4 redundant CORDIC algorithm with variable scale factor is proposed. The algorithm includes an on-line scale factor decomposition algorithm that transforms the complicated variable scale factor into a sequence of simple shift-and-add operations and does the variable scale factor compensation in the same fashion. On the other hand, the on-line decomposition algorithm i...

The objectives in this work were to develop, calibrate, and apply a model to predict ideal taper profiles down the narrow faces of the SIDERAR slab casting mold for several different casting speeds, steel grades, flux powder compositions, and widths. A significant amount of original research was undertaken for this challenging problem. A finite difference model of transient 1-D heat conduction ...
