Transformations are taking place within the distribution systems to cope with the congestions and reliability concerns. This paper presents a new technique to efficiently minimize power losses within the distribution system by optimally sizing and placing distributed generators (DGs) while considering network reconfiguration. The proposed technique is a hybridization of two metaheuristic-based algorithms: Grey Wolf Optimizer (GWO) and Particle Swarm Optimizer (PSO), which solve the network reconfiguration problem by optimally installing different DG types (conventional and renewable-based). Case studies carried out showed the proposed hybrid technique outperformed each algorithm operating individually regarding both voltage profile and reduction in system losses. Case studies are carried to measure and compare the performance of the proposed technique on three different works: IEEE 33-bus, IEEE 69-bus radial distribution system, and an actual 78-bus distribution system located at Cairo, Egypt. The integration of renewable energy with the distribution network, such as photovoltaic (PV) arrays, is recommended since Cairo enjoys an excellent actual record of irradiance according to the PV map of Egypt.

Nowadays Hazard Analysis of Critical Control Points (HACCP) has become a prerequisite for transactions involving food products. Whereas the implementation of the Hazard Analysis Critical Control Point (HACCP) system to chicken products is of great importance in order to produce microbiologically safe foods. Chicken sausage is one of the popular foodstuffs among products of chicken meat. Therefore a thorough HACCP analysis of this product has become an important issue for public health. This paper presenting guidelines for the application of HACCP and focuses on the flow diagrams based on the production line of manufacture chicken sausage in a small producing unite in Agriculture Research Center, and presents an analysis of the hazards and of the critical control points (CCP) and monitoring them then verification to confirm that the HACCP system is working effectively.

The aim of this investigation is to evaluate the consumed energy under surface and subsurface drip irrigation techniques in hyper arid condition of Siwa Oasis with using low quality water. Experimental treatments were done at Siwa Oasis-Matruh Governorate. The experimental results showed that energy applied efficiency (
