Effect Of Corrugation Properties On The Flexural Behavior Of Small-Scale Mono-Symmetric Steel Girders With Corrugated Webs, Ahmed Elgendy, Ahmed M. El Hadidy, Dr. Mahmoud Hassan Elboghdadi

Journal of Engineering Research

Steel girders with corrugated webs have been extensively researched and used in a variety of applications during the last few decades, including bridges and industrial buildings. Many studies explored the behavior of double symmetric girders with corrugated webs, but only a few articles used unequal flanges. Furthermore, the majority of research focuses on large-scale girders such as bridge girders, with just a few publications considering small-scale girders that may be employed in traditional construction applications. Additionally, performed investigations that consider the flexural behavior focused their studies on the effect of varying the dimensions of flanges without considering the effect of …

A New Method To Start Loaded Induction Motors, Omar El-Sayed Mohammed Youssef

Journal of Engineering Research

Three-phase induction motors have a widespread use in industry, and starting of loaded induction motors is an important matter. However, there are few studies on motor starting using variable-frequency drives (VFDs). The existing control schemes, described by these studies, have disadvantages such as dependence on derived characteristics, adjustment of settings, design of controllers, or burden of calculations on the control processor. In this paper, a simple and effective control scheme of VFDs to start loaded motors is proposed. In this scheme, there is no dependence on any characteristic, adjustment of settings, controllers, and rotor speed sensor. By this scheme, the …

Journal of Engineering Research

This study presents the combustion and emission results obtained from a laboratory furnace equipped with a 35 kW industrial burner that utilizes co-combustion of pulverized biomass and diesel fuel. The experiment compared the co-combustion of pulverized biomass and diesel fuel with diesel fuel alone. Three different loading ratios of pulverized biomass from residual beet samples were used. Temperatures were measured at various positions inside the furnace to analyze combustion performance. It was observed that increasing the biomass loading ratios led to higher flame temperatures and improved combustion compared to diesel fuel alone. The concentrations of pollutants such as Co, HC, …

Finite Element Investigation For The Flexural Behavior Of Small-Scale Mono-Symmetric Steel Girders With Corrugated Webs, Ahmed H. Elgendy, Ahmed M. El Hadidy, Dr. Mahmoud Hassan Elboghdadi

Journal of Engineering Research

In the last decades, steel girders with corrugated webs have been widely investigated and implemented in many applications such as bridges and industrial facilities. Many researchers investigated the flexural behavior of traditional doubly symmetric girders with corrugated webs, but a very limited number of investigations considered the usage of unequal flanges. In addition, for most cases the performed investigations focus on the behavior of large-scale girders similar to bridge girders, while few papers considered small-scale girders that could be used in traditional structures. Thus, the objective of this paper is to investigate the lateral torsional buckling behavior of small-scale unsymmetric …

Parametric Design As A Tool To Reduce Solar Penetration By Outdoor Shades In Hot Arid Climate, Rana O. Aboulfaraj, Iman O. Gawad, Mostafa Khalifa

Architecture and Planning Journal (APJ)

Conventional design methods and current tools infrequently link performance with the geometry of the design. These methods rarely enable backtracking through the design process and can't achieve full performance criteria. In this context, using both procedural geometry and information from numerical assessments and performance simulations should be discussed to support the search for effective solutions. Architects have gained control over the process of design by utilizing parametric methods to generate a sustainable design that interacts with sustainable, climatic, and environmental restrictions, particularly in hot arid zones where outdoor life is overlooked. This paper will discuss the performance-oriented design and a …

Faculty Publications

Achieving an optimal therapeutic level is crucial in effectively eradicating cancer cells during treatment. However, conventional chemotherapy-associated systemic administration of anticancer agents leads to many side effects. To achieve the desired control over the target site, active targeting of HER2-positive breast cancer cells can be achieved by conjugating liposomal vesicles with Human Epidermal growth factor Receptor 2 (HER2) and inducing release of the encapsulated drug using ultrasound. To further enhance the delivery efficiency, nanoemulsion droplets exhibiting responsiveness to low-frequency ultrasound are encapsulated within these lipid vesicles. In this study, we prepared four different liposomal formulations, namely pegylated liposomes …

Municipal Waste Management Based On Geomechanical Assessments Of The Landfill Site Slope – A Case Study In Southern Poland, Tomasz Janoszek, Phu Minh Vuong Nguyen, Jacek Grabowski

Journal of Sustainable Mining

Over time, municipal waste landfills tend to go higher and become larger. The stability of the municipal landfill slope is one of the basic geotechnical tasks. This task ensures continuous waste deposition on the landfill surface and safety in its surroundings. With the increasing height and volume of the landfill, it is difficult to estimate the available area of the municipal landfill, where more waste can be safely deposited due to a number of variable factors, such as the geotechnical conditions of the municipal landfill, the morphological composition, age, and degree of compaction and decomposition of the deposited waste.
