Novel structures of fractional-order differentiation and integration stages are presented in this work, where passive resistors are not required for their implementation. This has been achieved by considering the inherent resistive behavior of fractional-order capacitors. The implementation of the presented stages is performed using a current feedback operational amplifier as active element and

Non-integer power-law all-pass transfer functions, are approximated by suitable integer-order transfer functions in this work. The derivation of the integer-order transfer functions is based on the analytic expansion of the (non-integer) power-law transfer functions through the utilization of the binomial theorem. The offered benefit is the derivation of stable integer-order transfer functions

Adulteration of vinegar to gain economic benefit has become a common practice in recent years. RP-HPLC strategies were proposed for the assurance of the concentration of acetic acid, rare organic acids (tartaric, malic, lactic and citric), and acetaldehyde in Egyptian vinegar samples. The flow rate was 0.5 mL/min using UV detection at 210 and 365 nm for organic acid and acetaldehyde, respectively

Agricultural land expansion is a solution to address global food security challenges in the context of climate change. However, the sustainability of expansion in arid countries is difficult because of scarce surface water resources, groundwater salinity, and the health of salt-affected soil. Developing expansion and sustainability plans for agriculture requires systems thinking, considering the

Aim The aim of this research was to study serum vitamin D and micro-ribonucleic acid-146a (miRNA-146a) expression in dry eye disease (DED) associated with rheumatoid arthritis (RA) and their clinical correlations to DED parameters. Setting and design This is an observational cross-sectional study that was conducted at Cairo University, Cairo, Egypt. Patients and methods The study participants were

This study examines how a large negative economic shock impacts marriage rates for young men in the West Bank. Utilizing data from before and after the sudden and abrupt closure of the Israeli labor market for Palestinian commuters from the West Bank in 2001, our empirical design employs a difference-in-difference strategy and uses the variations in localities’ exposure to the Israeli labor market

Medicines based on messenger RNA (mRNA) hold immense potential, as evidenced by their rapid deployment as COVID-19 vaccines. However, worldwide distribution of mRNA molecules has been limited by their thermostability, which is fundamentally limited by the intrinsic instability of RNA molecules to a chemical degradation reaction called in-line hydrolysis. Predicting the degradation of an RNA

Purpose: This paper aims to deepen our understanding of how serious games could be used for learning in organizations to empower brand performance and image sustaining competitive advantage from a Resource Based View (RBV) perspective and to examine the practical implications of the evolving technologies for employers. Design/methodology/approach: The research methodology is based on a qualitative

Internet of Vehicles is considered one of the most unprecedented outputs of the Internet of Things. No one has realized or even expected the rapidly-growing revolution regarding autonomous connected vehicles. Nowadays, Internet of Vehicles is massively progressing from Vehicular Ad-Hoc Networks as a huge futuristic research and development discipline. This paper proposes a novel reliable and

The accelerated rise of new technologies has reshaped the manufacturing industry of contemporary vehicles. Numerous technologies and applications have completely revolutionized the driving experience in terms of both safety and convenience. Although vehicles are now connected and equipped with a multitude of sensors and radars for collision avoidance, millions of people suffer serious accidents on
