Accurate Molar Mass Estimation of Polyolefin Blends Using High Temperature-size Exclusion Chromatography With Triple Detection: Insight Into Molecular Level Mixing of Polypropylene With Various Application Grades of Polyethylene.

In this study, a commercially available polypropylene homopolymer (H-PP) was blended with blow molding polyethylene (PE) grade via melt mixing using a compounding machine. The resulting blends were subjected to high-temperature size exclusion chromatography (SEC) analysis, coupled with infrared-5 (IR-5), viscometer (VISCO), and multi-angle laser light scattering (MALS) detectors. The molecular weight (MW) and MW distributions were investigated using SEC, and the exact blend compositions were evaluated using C nuclear magnetic resonance.

State of Lung Cancer in Egypt: Moving Towards Improved Guidelines for Prevention, Screening, Treatment, and Clinical Care Programs.

Lung cancer remains a leading cause of cancer-related mortality globally and presents significant challenges in Egypt. In 2023, the first annual meeting of the Thoracic Oncology Multidisciplinary Faculty, organized by the Egyptian Cancer Research Network and the Egyptian Society of Respiratory Neoplasms, was held in Cairo, Egypt. The meeting aimed to address gaps in lung cancer management across Egypt and the broader Middle East and North Africa region.

Impact of urgent care centers on emergency department visits in Al Madina Al Munawara: A pre-post study.

Objectives: To evaluate the impact of UCCs on reducing non-urgent Emergency Department (ED) visits and improving patient flow, focusing on metrics such as door-to-doctor time, doctor-to-decision time, and overall patient disposition.

Methods: This observational cohort pre-post study analyzed data from 198,050 ED visits to King Fahad Hospital, Al Madina Al Munawara between June 2021 and May 2023 and compared visit patterns before and after UCC implementation.

Results: Post-UCC implementation, the average door-to-doctor time decreased but was not statistically significant.

Age-specific vulnerability and high prevalence of delirium in pediatric intensive care based on a prospective cohort study.

Delirium, a neuropsychiatric syndrome characterized by acute disruptions in attention and awareness, significantly impacts children in Pediatric Intensive Care Units (PICUs), leading to prolonged hospitalization, increased infection risk, and dependence on mechanical ventilation. Despite growing recognition, its true burden and risk factors in children remain poorly understood. This prospective cohort study investigated the prevalence, characteristics, and potential therapeutic targets for delirium in 890 children admitted to a tertiary PICU between January and December 2022.

Novel versions of Hölder's-Like and related inequalities with newly defined space, and their applications over fuzzy domain.

It is widely recognized that fuzzy number theory relies on the characteristic function. However, within the fuzzy realm, the characteristic function transforms into a membership function contingent upon the interval [0,1]. This implies that real numbers and intervals represent exceptional cases of fuzzy numbers.
