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 before the shock. The closure reduced the employment and income of adult men asymmetrically across localities. Our findings show that the closure caused a reduction in marriage rates among young men

This study aimed to identify the interactions between the sub-systems of the supply chain system of milled grain products, in South Africa, namely: (1) farming (agricultural); (2) transport (transportation); (3) manufacturing (milling); and (4) trade (retail). Furthermore, this paper investigated how these sub-systems are affected by economic and natural external factors namely: (1) the exchange rate between ZAR and USD; (2) the price of international crude oil; and (3) climate change and/or droughts. For this purpose, system dynamics (SD) model was developed and used, which enabled to

Water contamination with paints causes a colour agent to the water that negatively affects the environment, organisms, and humans. Different physicochemical processes are applied for wastewater treatment; however, they have many drawbacks such as high cost, generating toxic waste, and non-effective at low concentrations. Adsorption is considered a promising technique for pollutant removal from polluted wastewater. Commercial activated carbon, nano-materials, and natural biological materials are used as adsorbents in adsorption. This chapter focuses on discussing the adsorption process, the

Diabetes is a common chronic metabolic disease with a wide range of clinical symptoms and consequences and one of the main causes of death. For the management of diabetes, painless and continuous interstitial fluid (ISF) glucose monitoring is ideal. Here, we demonstrate continuous diabetes monitoring using an integrated microneedle (MN) biosensor with an emergency alert system. MNs are a novel technique in the field of biomedical engineering because of their ability to analyze bioinformation with minimal invasion. In this work we developed a poly(methyl methacrylate) (PMMA) based MN glucose

Myosins are essential components of organelle trafficking in all the eukaryotic cells. Myosin driven movement plays a vital role in the development of pollen tubes, root hairs and root tips of flowering plants. The present research characterized the myosin genes in Arabidopsis thaliana and Helianthus annuus by using different computational tools. We discovered a total of 50 myosin genes and their splice variants in both pant species. Phylogenetic analysis indicated that myosin genes were divided into four subclasses. Chromosomal location revealed that myosin genes were located on all five

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 divided into three groups: group A, DED/RA (n=35); group B, non-DED/RA (n=36); and group C, non-DED/non-RA (n=35). All participants were assessed for ocular surface disease index, tear breakup time

Retinal prostheses are designed to aid individuals with retinal degenerative conditions such as Retinitis Pigmentosa (RP) and Age-related Macular Degeneration (AMD). These prostheses seek to restore vision and improve the perceived scene by stimulating degenerated retinal cells using retinal stimulating electrodes. While these electrodes allow more efficient interaction with the surroundings, they offer limited resolution.This paper presents an innovative approach to revolutionize the visual perception of retinal prosthesis users. The key idea behind the proposed approach is to fuse

Omnidirectional mobile robots are considered for many research applications due to their maneuverability in tight spaces and smoothness of motion. This paper presents a novel design of a T-model mecanum wheeled mobile robot (3-MWMR), the derivation of the inverse and forward kinematics model of the proposed robot, the physical body design of the proposed T-model shape, the simulation of the system dynamics and omnidirectional capabilities of the robot on CoppeliaSim V-rep and MATLAB. The experimental results obtained validates the proof of concept of the proposed model for reduced power losses

mobile robots play an enormous role in different fields of daily life applications including military, safety, and logistic multi-tasking capabilities. A new approach is introduced to the market which is the 3 Mecanum wheeled mobile robot (3-MWMR) is being tested and validated. The main goal of the proposed design is to achieve all the desired directions of motion and to improve the performance of the mobile robot in avoiding obstacles using the fuzzy logic controller. © 2022 IEEE.

In a search for new drug candidates for one of the neglected tropical diseases, leishmaniasis, twenty quinoline-isatin hybrids were synthesized and tested for their in vitro antileishmanial activity against Leishmania major strain. All the synthesized compounds showed promising in vitro activity against the promastigote form in a low micromolar range (IC50 = 0.5084–5.9486 μM) superior to the reference miltefosine (IC50 = 7.8976 μM). All the target compounds were then tested against the intracellular amastigote form and showed promising inhibition effects (IC50 = 0.60442–8.2948 μM versus 8.08
