Impacts of COVID-19 and the Russian–Ukrainian Conflict on Food Supply Chain: A Case Study from Bread Supply Chain in Egypt Noha A. Mostafa, Abdelwahab A. Hussein, Mohab Elsheeta, Giovanni Romagnoli Sustainability Switzerland, 2024 The COVID-19 pandemic and the Russian–Ukrainian war have significantly impacted global supply chains, including the food supply chain, in numerous countries. As one of the leading wheat importers, Egypt has been adversely affected by the simultaneous occurrence of these two events. Baladi bread is an integral part of the daily diet in Egypt, so any disruption affecting its availability can have a severe impact on the country’s food security. This study aims to simulate the causes and effects of potential disruptions that could occur, such as increased transportation time, unavailability of sourcing, and surge in demand due to lockdowns and panic buying. The East Cairo region was chosen as a case study to model the Baladi bread supply chain. A discrete-event simulation model was developed using anyLogistix software (version 2.15.1) for this study. Five key performance indicators were selected to evaluate, analyze, and compare the outcomes of each scenario in terms of the performance and operation of the food supply chain: service level by product, lead time, demand backlog, average daily available inventory in the mills, and on-hand inventory of wheat in the silos. The results indicate that the supply chain has been significantly impacted by the disruptions caused by these two events, leading to decreased availability of Baladi bread, unmet demand, extended lead times, and high backlogs. By utilizing the research findings, proactive strategies can be developed to minimize the impact of such disruptions in the future and maximize food security and supply chain resilience.
Guidelines for data collection on energy performance of higher-education buildings in Egypt: a case study Hesham Safwat, Ahmed A Abdel-Rehim, Iman El-Mahallawi, Abdelwahab A. Hussein, Ahmed M. Amer, Engy Elshazly, Ahmad I. Elshamy Hbrc Journal, 2024 Reliable energy analysis of buildings relies heavily on high-quality data leading to proper indicators. Previous studies have highlighted the importance of data quality in analyzing energy usage in residential and non-residential buildings in order to transform declarations to actions, optimise energy efficiency policies and monitor progress and failures in countries. Collected data must adhere to national and international standards for energy performance in buildings. This study aims to provide practical guidelines for effectively collecting and preparing data suitable for evaluating energy performance in Egyptian higher-education (HE) buildings. The guidelines are developed based on a comprehensive case study, considering data availability in typical educational facilities. Architectural and civil engineering drawings, construction specifications, and occupancy details are accessible. However, actual monthly electrical and natural gas consumption data for individual buildings are lacking. To address this, the study proposes the creation of detailed datasheets for each building, encompassing all energy sources and their electrical and power specifications, such as equipment, machinery, and HVAC systems. These datasheets were utilized to calculate energy consumption and energy usage indicators (EUI). The findings demonstrate that the datasheets enable adequate assessment of energy usage in various spaces within educational buildings, including staff rooms, lecture halls, and laboratories. This facilitates the identification of areas in need of targeted energy efficiency improvements. Notably, the study reveals that electricity consumption in the Faculty of Engineering building is significantly influenced by PCs, laboratories, lighting, and air conditioning.
Erosion wear assessment of sugarcane fibre reinforced polymer composites for applications of wind turbine blades N.S.M. El-Tayeb, Tamer A. Mohamed, Abdelwahab A. Hussein, Mahmoud Elthakaby Journal of Polymer Research, 2023 This research reports erosion wear characteristics of polyester matrix composite reinforced with short fibres of sugar cane. Erosion tests were conducted using silica sand particles of size (200–500 µm) using a locally designed air jet-type erosion test rig. The sugarcane fibre-reinforced polyester composites (5% wt.) with different fibre lengths (3, 12, 48 mm) were impacted by sand particles at a fixed velocity of 60 m/s, impact angles (30°, 60°, 90°) and erodent weight of (2500,7500) gm. ANOVA approach was used to determine the most significant parameter and their combinations that minimize the erosion rate. Scanning Electron Microscope (SEM) observations were conducted to investigate the erosion mechanisms. Results indicated that the erosion rate is greatly influenced by fibre length as well as the erodent weight. Moreover, at an erodent weight of 2500gm, the behaviour of the material turns from brittle into ductile. At an erodent weight of 7500gm, the erosion rate is inversely proportional to the fibre length.
Techno-economic Evaluation and Environmental Benefit of PV-based Electric Vehicle Charging Station on University Campus Ahmad I. ElShamy, Abdelwahab A. Hussein, Seif ElBadry, Engy Elshazly, Rania Rushdy Moussa, Iman S. El-Mahallawi 2023 2nd International Conference on Smart Cities 4 0 Smart Cities 4 0 2023, 2023 Smart utilities comprise an important aspect of modern smart cities. The aim of this work is to present a case study for implementing a solar- energy based electric vehicle charging station (for the first time on a campus in Egypt) at the British University in Egypt. The total amount of energy needed for charging each electric vehicle (EV) was estimated to be 13.3-16.2 kWh. The EV is operated by 12 batteries. The station was designed to provide energy sufficient for charging up to two vehicles daily during summer. Thus, the station sizing was based on provision of 16.2 KW and the system components were designed and selected accordingly. Measurements were made to evaluate the system output, efficiencies and solar radiation in both summer and winter. The results indicate that these parameters vary with day time. The economic study showed that the payback period is 10 years and 6 months. The environmental study showed that such system will save around 7,968.96 kg/kWh/year of CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> emissions yearly.
