Experimental Investigation on the Flexural Capacity of Reinforced Concrete Beams with Treated Wastewater and Recycled Concrete Aggregates by Abushanab, Abdelrahman

“…Therefore, the present study explores the feasibility of employing treated wastewater (TWW), recycled concrete aggregates (RCA), and fly ash (FA) in concrete mixes. A total of 4 reinforced concrete (RC) beams were investigated under 4-point bending setup with three parameters investigated; namely, mixing water (fresh water and TWW), coarse aggregates (gabbro and RCA), and cementitious binders (cement and FA). …”

Timetabling hub-and-spoke parcel distribution inter-facility network by Ben-Ayed, Omar

“…This problem, which comes after generating the network design and before implementing it, is concerned with parcel timetabling. A non-linear model, composed of the shipping-time objective function and the time-precedence constraints, is developed in order to optimise the daily movements of parcels from their origins to their destinations. …”

Kappa-Distributed Electrons in Solar Outflows: Beam-Plasma Instabilities and Radio Emissions by Lazar, M.

“…The frequency downshift, also revealed by the observations, clearly tends to increase in the presence of a Kappa-distributed beam. Particle-in-cell (PIC) simulations confirm the inhibiting effects of (initially) Kappa-distributed electrons, but these minor effects in the linear and quasi-linear phases unexpectedly lead to significant decreases in the wave energy levels of the (primary) ES fluctuations near the plasma frequency and higher harmonics. …”
