Escalating SOx and NOx emissions from industrial plants necessitates customized scrubbing solutions to improve removal efficiency and tackle cost limitations in existing wet FGD units. This work investigates the real-time intensified removal pathways via an innovative two-stage countercurrent spray tower configuration strategically integrating NaOH (M) and NaOH/NaClO (M/M) to remove SOx and NOx emissions simultaneously from the industrial stack through a comprehensive parametric study of absorbents concentration, reaction temperature, gas flow rate, liquid to gas ratio (F/F), and absorbent showering head. Flue gas stream comprising SO bearing 4500 ppm, SO bearing 300 ppm, 70 ppm NO, and 50 ppm NO brought into contact with two scrubbing solutions as M, and a complex absorbent of M/M at varying respective ratios.

Methods: Raw infrared PPG data is collected from the finger-tip of 173 appar- ently healthy subjects, aged 3-61 years, via a non-invasive low- cost MAX30102 PPG sensor. In addition, the following metadata is recorded for each subject: age, gender, height, weight, family history of cardiac disease, smoking history, vitals (heart rate and SpO2).

Background: The anti-inflammatory and antimicrobial benefits of prebiotics may present an affordable and cost-effective strategy for not only the prevention but also treatment of malnutrition. Therefore, the present trial has been designed with the aim to evaluate the role of prebiotics on the gut microbiome of severe acute malnourished (SAM) children.
Methods: The study is designed as a prospective, double-blinded, triple-armed, multi-centered randomized controlled trial, with 6-59 months old uncomplicated SAM children recruited to the experimental group receiving ready-to-use therapeutic food (RUTF) plus prebiotics and the active comparator group receiving RUTF plus starch for 2 months duration (8 weeks).
The synthesis of gold nanoparticles (AuNPs) green methods is advantageous due to their economic viability, reduced environmental pollution, and safety towards human health. According to our best knowledge, there is limited documented research on synthesizing AuNPs using gum Arabic (GA) and cinnamon (CNM) and studying their anticancer activities against colorectal cancer cells. This study presents a simple approach to synthesizing AuNPs using GA and CNM, characterized by advanced analytical techniques, including UV-Vis and FTIR spectroscopies, SEM, EDS, TEM, SAED, Zeta sizer, and Zeta potential.
