Comparative analysis of correlation and causality inference in water quality problems with emphasis on TDS Karkheh River in Iran.

Water quality management is a critical aspect of environmental sustainability, particularly in arid and semi-arid regions such as Iran where water scarcity is compounded by quality degradation. This study delves into the causal relationships influencing water quality, focusing on Total Dissolved Solids (TDS) as a primary indicator in the Karkheh River, southwest Iran. Utilizing a comprehensive dataset spanning 50 years (1968-2018), this research integrates Machine Learning (ML) techniques to examine correlations and infer causality among multiple parameters, including flow rate (Q), Sodium (Na), Magnesium (Mg), Calcium (Ca), Chloride (Cl), Sulfate (SO), Bicarbonates (HCO), and pH.

Factors associated with hospital length of stay in patients with thoracic hydatid cyst disease undergoing surgical intervention: a retrospective study.

Background: Hydatid cyst (HC) frequently affects the lungs, making it the second most common site after the liver. This study evaluated the clinical characteristics, surgical procedures, complications, laboratory findings, and factors influencing hospital length of stay (LOS) in patients undergoing surgery for pulmonary hydatid cysts.

Methods: This retrospective observational study included adult patients who underwent surgery for lung HC between 2017 and 2021.

Mussel-inspired modified regenerated cellulose as tissue adhesive and antibacterial gauze: A promising approach for rapid hemostasis in non-compressible hemorrhage.

Uncontrollable hemorrhage leads to high mortality rates; thus, engineering effective hemostatic materials is crucial for rapid hemostasis. Developing hemostatic materials for rapid coagulation, antibacterial activity, and easy removal without compromising clot integrity remains a challenge. Herein, a multifunctional hemostatic gauze was engineered by modifying regenerated cellulose textile through multiple sequential chemical reactions, including carboxymethylation, crosslinking with CaCl/ZnCl solution, oxidation, and polymerization with dopamine.

Spatial and temporal variation of façade-level particle number concentrations using portable monitors in Copenhagen, Denmark.

Ultrafine particles (UFP), commonly expressed as particle number concentrations (PNC), have been associated with harm to human health yet are currently not regulated or routinely monitored in many places. This has limited the potential for studies of health effects of long-term exposure to UFP. The present study aims to understand the spatial and temporal variation in façade-level UFP exposures in Copenhagen, Denmark.
