Evaluation of anion exchange resin for sorption of selenium (IV) from aqueous solutions.

In this work, selenium (IV) ions were adsorbed from aqueous solutions by the strongly basic anion exchange resin Amberlite IRA-400. The morphology of the resin before and after Se(IV) sorption was investigated using different techniques such as energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). To determine the ideal sorption conditions, a batch approach was used to examine the variables affecting Se(IV) sorption performance, including pH, shaking time, adsorbent dosage, initial metal ion concentration, and temperature.

Recent developments and future directions in point-of-care next-generation CRISPR-based rapid diagnosis.

The demand for sensitive, rapid, and affordable diagnostic techniques has surged, particularly following the COVID-19 pandemic, driving the development of CRISPR-based diagnostic tools that utilize Cas effector proteins (such as Cas9, Cas12, and Cas13) as viable alternatives to traditional nucleic acid-based detection methods. These CRISPR systems, often integrated with biosensing and amplification technologies, provide precise, rapid, and portable diagnostics, making on-site testing without the need for extensive infrastructure feasible, especially in underserved or rural areas. In contrast, traditional diagnostic methods, while still essential, are often limited by the need for costly equipment and skilled operators, restricting their accessibility.

Machine learning boosts wind turbine efficiency with smart failure detection and strategic placement.

The research study objective seeks to improve the efficiency of wind turbines using state-of-the-art techniques in the domain of ML, making wind energy the key player in fashioning a favorable future. Wind Turbine Health Monitoring (WTHM) is typically achieved through either vibration analysis or by using Supervisory Control and Data Acquisition (SCADA) data of wind turbines, wherein conventional fault pattern identification is a time-consuming, guesswork process. This work proposed an intelligent automated approach to early fault detection through the implementation of the HARO (Huber Adam Regression Optimizer) model, which combines Transformer networks with Lasso Regression and the Adam optimizer.

This study aimed to predict the toughness of date palm fruit (Barhi, Saqie, and Khodry varieties) at different ripening stages (Khalal, Rutab, and Tamar) using Hertz Theory by evaluating the physical and mechanical characteristics of the fruits. Physical measurements revealed that high moisture content in the Khalal stage led to larger dimensions and mass across all varieties, with Barhi dates showing a moisture content of 63.31%, which decreased to 32.

Clinical characteristics of anti-myelin oligodendrocyte glycoprotein antibody among aquaporin-4 negative neuromyelitis optica spectrum disorders in Egyptian patients.

Some patients with neuromyelitis optica spectrum disorder (NMOSD)-like symptoms test negative for anti-aquaporin-4 (anti-AQP4) antibodies. Among them, a subset has antibodies targeting myelin oligodendrocyte glycoprotein (MOG), a condition now termed MOG antibody-associated disease (MOGAD). MOGAD shares features with NMOSD, like optic neuritis and myelitis, but differs in pathophysiology, clinical presentation, imaging findings, and biomarkers.

CASR, CLDN 14, ALPL & SLC34A1 genes are associated with the risk of nephrolithiasis in Egyptian children.

Backgrounds: The pathophysiology of nephrolithiasis is complex, influenced by both environmental and genetic factors. Calcium is the most prevalent metabolite present in the stone matrix. Stimulating the basolateral calcium sensing receptor (CASR) in the renal tubules leads to an increase in claudin-14 expression, reducing paracellular calcium permeability and increasing urinary Ca excretion.
