Recycling of hospital laundry wastewater using membrane technology
(
Desalination Publications
, 2017 , Article)
The laundry wastewater from a Qatari hospital has been characterized and its membrane filtration behavior studied. 1,800-2,500 L or wastewater per cycle for washing a laundry load of 40-50 kg was determined, with the ...

Purpose - The purpose of this paper is to examine if the simultaneous openness to trade and capital account can promote financial sector development. Design/methodology/approach - Based on a sample of 12 Arab countries ...
Experimental measurements and modelling of viscosity and density of calcium and potassium chlorides ternary solutions
(
Nature Research
, 2020 , Article)
Measured viscosity and density data for ternary aqueous solutions of CaCl2 and KCl are presented at temperatures between 293 and 323�K with 5�K increment. A modified Jones?Dole was introduced by adding extra terms and ...
Validity of the effective potential method to study PT-symmetric field theories
(
Elsevier B.V.
, 2019 , Article)
We calculate the one loop effective potential for the class (-(iϕ)α) of PT-symmetric and non-Hermitian field theories in 0+1 space-time dimensions. To test the method, we showed that for the massless Hermitian ϕ4 theory, ...

(
Emerald Group Publishing Ltd.
, 2015 , Article)
Purpose - The purpose of this paper is to identify and develop a hierarchical model for the barriers affecting the growth of mobile commerce (M-commerce). Based on the model developed, the authors' objective is to identify ...
High-speed auxiliary fault location element for distance relays in double-circuit lines
(
Elsevier
, 2021 , Article)
In multi-zone distance relays, zone-2 has an intentional time delay which is considered for the coordination among the other distance relays. This delay is unnecessary for faults that occur at the end of the protected line ...
Near surface embedded-FRCM for flexural strengthening of reinforced concrete beams
(
Elsevier Ltd
, 2019 , Article)
Fibre reinforced cementitious matrix (FRCM) systems are mostly externally bonded (EB) for the strengthening of reinforced concrete (RC) and masonry structures. In this paper, the relatively new concept of near-surface ...
A fouling suppression system in submerged membrane bioreactors using dielectrophoretic forces
(
Elsevier
, 2015 , Article)
A novel method was developed to suppress membrane fouling in submerged membrane bioreactors. The method is based on the dielectrophoretic (DEP) motion of particles in an inhomogeneous electrical field. Using a real sample ...
T-tetrominoes tiling's Markov chain mixes fast
(
Elsevier B.V.
, 2018 , Article)
Korn and Pak (2007) [3] conjectured that there exists a fully polynomial randomized approximation scheme (fpras) for approximating the number of ways of tiling a 4n x 4m rectangular lattice with T-tetrominoes. Using a flow ...
