Adequate curing of concrete is a fundamental step in concrete manufacturing to meet performance and durability requirements. Internal curing is a technique that can provide water to concrete for extended durations towards thorough hydration of the cement and reduced cracking. This work addresses potential use of two substitutes of ordinary aggregates for internal curing. Perlite as well as

Trajectory tracking of unmanned aerial vehicles (UAVs) has been studied nowadays because it is necessary to design new controllers under different conditions. Severe atmospheric conditions are one of the major problems to overcome according to the path of the UAV. Conditions such as wind speed that can vary according to the weather conditions can affect the flight performance and of course in

As the main pillar of the Smart City, Smart Highway manifests the centralized connectivity concept between the self-driving vehicles. Internet of Vehicle or IoV is the solution for improved connectivity between driverless vehicles. One of the major challenges in IoV research is the lack of datasets available. That is why the Internet of vehicles is one of the hot topics in research nowadays. IoV

In this contribution, a mathematical model is presented for the flow of molten salt in a circular pipe. The fluid density, thermal conductivity, and viscosity are all assumed to be temperature dependent. We show how to derive a new closed-form approximate solution to this problem, valid for low Reynolds numbers and high axial temperature gradients. This regime is chosen to challenge the ability of

Functional materials incorporate dielectrics, piezoelectrics, ferroelectrics, semiconductors, and superconductors. They have exceptional properties depending on their structure, shape, and arrangement. Their properties can be modified and adjusted for several applications such as energy storage, microsystems, and microelectromechanical systems. Functional materials could perform a specific

Entrepreneurship is a key catalyst of any economic growth, and Egyptian entrepreneurs tried to prevail. Their number grew rapidly during the past decade. But the statistics still alarming as many of them fail and seize to continue. This study tries to identify key constraints that deter young people from starting and running their own businesses and tries also to identify incentives and stimuli

Visibility graphs (VGs), horizontal visibility graphs (HVGs) and the sandbox algorithm (SB) are applied for multifractal characterization of complex network systems that are converted from time series measurements, are used to characterize the fluctuations in pseudorapidity densities of singly charged particles produced in 16O-AgBr interactions at 60AGeV. The work presents the analysis of ring

The primary by-product of the sugarcane industry is sugarcane bagasse, which is considered a raw material for molded tableware production process. Studies proved that this industry is energy and water intensive. Attempts have been conducted to produce biodegradable bagasse plates utilizing a novel drying technique for the bagasse pulp using mechanical rollers for dehydration and cold drying

The exploitation of fractional calculus in engineering applications requires the utilization of fractional-order elements. As there is no immediate access to such type of elements, emulators that proportionally imitate their behavior are developed. The realization of emulators of fractional-order elements is based on the approximation of their impedance function. Subsequently, an advantageous

This study uses visual, quantitative content analysis to examine whether there is a significant difference in the representation of veiled versus nonveiled women in branded Instagram posts. We also tested the representation of women in Western and Egyptian branded Instagram posts. We used a sample of 200 branded Instagram posts created to promote products and services. The study tested five
