Interfacial improvement of carbon fiber/polyoxymethylene composites by depositing functionalized carbon nanotubes on the fibers

CF/POM/CNT ternary composites have been prepared by melt blending method with carbon nanotubes (CNT) asmodifier, maleic anhydride (MAH) as interfacial compatibilizer and polyoxymethylene (POM) as matrix. The mechanicalproperties of CNT on CF/POM have been studied by temperature-controlled tensile, and scanning electron microscopyanalysis. The results show that the interface properties of CF/ POM/CNT ternary composites can be improved by addingMAH, thus improving the mechanical properties of the composites. The tensile strength, bending strength and impactstrength of the ternary composite at room temperature have increased, and the tensile strength of CF/POM/CNT ternarycomposites has improved by 12.1%

Morphology, rheology and physical properties investigations of multi-scale nano-zinc oxide modified asphalt binder

The study investigates the impact of incorporating multi-scale nano-zinc oxide (nano-ZnO) particles into a PG 64–22 asphalt binder, exploring changes in morphology, rheology, and physical properties. Utilizing nano-ZnO particles of varying sizes (10–30 nm, 50–70 nm, 100–200 nm) and concentrations (1–5%), the research employs Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM) for morphological analysis and Dynamic Shear Rheometer (DSR) testing for rheological properties. The findings reveal substantial improvements in binder elasticity and rutting resistance, with notable enhancements in physical attributes such as lower penetration grades, higher ductility, and increased softening points. Additionally, nano-ZnO modified binders demonstrate superior aging resistance, maintaining their enhanced properties after both short-term and long-term aging tests. This comprehensive study underscores the potential of nano-ZnO as an effective modifier in asphalt binders, promising increased durability and resilience against common roadway distresses

Relation between triglycerides and the severity of acute pancreatitis combined with nonalcoholic fatty liver disease: a retrospective study

Abstract Background Nonalcoholic fatty liver disease (NAFLD) can exacerbate the severity of acute pancreatitis (AP), and this severity is worsened with increased severity of NAFLD. This study aimed to investigate the relation between serum triglyceride (TG) and the severity of AP with NAFLD by collecting clinical data from AP patients with NAFLD. Methods AP patients with NAFLD were divided into 2 groups according to TG levels: hypertriglyceridemia (HTG) group and non-hypertriglyceridemia (NHTG) group. Results In total, 598 AP patients with NAFLD were enrolled in this study, including 433 in the HTG group and 165 in the NHTG group. Compared with the NHTG group, AP patients in the HTG group were more serious (P < 0.05). The incidence of persistent organ failure (POF), especially persistent respiratory failure, and the ratio of acute peripancreatic fluid collection (APFC) were higher in the HTG group (P < 0.05). Higher TG levels were associated with a higher incidence of APFC (P < 0.05). Logistic regression analysis showed that the risk of APFC was significantly higher in moderate and severe NAFLD than in mild NAFLD. Conclusion HTG may aggravate the severity and local complications of AP combined with NAFLD

Discharge protocol in acute pancreatitis: an international survey and cohort analysis.

There are several overlapping clinical practice guidelines in acute pancreatitis (AP), however, none of them contains suggestions on patient discharge. The Hungarian Pancreatic Study Group (HPSG) has recently developed a laboratory data and symptom-based discharge protocol which needs to be validated. (1) A survey was conducted involving all members of the International Association of Pancreatology (IAP) to understand the characteristics of international discharge protocols. (2) We investigated the safety and effectiveness of the HPSG-discharge protocol. According to our international survey, 87.5% (49/56) of the centres had no discharge protocol. Patients discharged based on protocols have a significantly shorter median length of hospitalization (LOH) (7 (5;10) days vs. 8 (5;12) days) p < 0.001), and a lower rate of readmission due to recurrent AP episodes (p = 0.005). There was no difference in median discharge CRP level among the international cohorts (p = 0.586). HPSG-protocol resulted in the shortest LOH (6 (5;9) days) and highest median CRP (35.40 (13.78; 68.40) mg/l). Safety was confirmed by the low rate of readmittance (n = 35; 5%). Discharge protocol is necessary in AP. The discharge protocol used in this study is the first clinically proven protocol. Developing and testifying further protocols are needed to better standardize patients' care
