This study, conducted in Shosha, Minia, Egypt, aimed to evaluate the effects of magnetically treated saline groundwater on both soil characteristics and the performance of tomato crops grown in arid sandy soils. The influence of magnetic fields on water quality was first assessed to determine its suitability for irrigation. Subsequently, the combined effects of MWT with different irrigation methods—namely, surface drip irrigat...

The reliability of the criteria adopted by the seismic codes in the United States (ASCE/SEI-7-16), in Europe (EC-8) and Egypt (ECP201-2012), that are used in distinguish torsionally irregular from torsionally regular Normal-Strength Concrete (NSC) and High-Strength Concrete (HSC) multistory 3-D buildings have been studied. The Static Equivalent Lateral Force (SELF) methods used by these codes for predicting the torsional momen...

Optimizing feeding rates in recirculating aquaculture systems (RAS) is crucial for ensuring fish growth, health, and system efficiency. This research introduces a novel approach to RAS feeding control using a Deep Deterministic Policy Gradient (DDPG) reinforcement learning algorithm. The developed system integrates feeding rate optimization with comprehensive water quality management to improve overall performance and stabilit...

The aim of this study is to identify the hidden etiologies of the black chromo-shifting transient phenomenon affecting Nile tilapia, Oreochromis niloticus , farmed in RAS-controlled ponds together with the assessment of the immunological reaction against the chronic irritating effects of the invasive agent. A total of 100 Nile Tilapia were collected from a private farm at Kafrelsheikh Province, located on the northern side of...
