The Middle East, a pivotal player in global energy markets, faces a confluence of challenges and opportunities as it navigates a transition towards sustainable energy systems. This region is home to five of the top ten oil producers in the world, and three of the top twenty gas producers. Shifting dynamics in energy demand, combined with pressing concerns for mankind to address global climate chan

The use of virtual learning environments is increasing, and it raises the question of how the environments are designed to benefit learning outcomes. The Cognitive Load Theory is a well-established framework for instructional design of learning environments, and introduces different design principles, based on a working memory model. This paper describes how these principles can be used in the des

This chapter summarizes current knowledge and diagnostic criteria for T-cell prolymphocytic leukemia (T-PLL). T-PLL is an aggressive disease characterized by a proliferation of small to medium-sized lymphocytes with a postthymic phenotype usually involving the blood, bone marrow, lymph nodes, spleen, and skin. The leukemic cells are usually positive for CD2, CD3 CD5, CD7, CD43, CD52, and CD26, but

Proposals that gesture played a pivotal role in the evolution of language have been highly influential. However, there are many differences between gestural origin theories, including different definitions of 'gesture' itself. We use a cognitive semiotic approach in order to categorize and review these theories. A semiotic system is a combination of signs or signals of particular type, defined by

Background: Dyspnea is a common and diagnostically challenging symptom in the emergency department (ED), particularly among older adults with multimorbidity. Traditional risk stratification tools often perform poorly in this population. Galectin-3 (Gal-3), a biomarker of inflammation and fibrosis, may reflect biological aging and resilience, potentially improving early mortality risk assessment.Ob

The elastic properties of amorphous TiNiSn, a promising half-Heusler system for flexible and wearable devices, were investigated using experimental and theoretical methods. Nanoindentation measurements performed on amorphous TiNiSn thin film grown by magnetron sputtering yielded an elastic (Young’s) modulus value of 132 GPa. To corroborate this result, density functional theory (DFT) calculations The elastic properties of amorphous TiNiSn, a promising half-Heusler system for flexible and wearable devices, were investigated using experimental and theoretical methods.

BACKGROUND: Peptic gastroduodenal stenosis is a rare but disabling condition causing gastric outlet obstruction. This study aimed to evaluate endoscopic balloon dilation in terms of treatment effectiveness, durability, and identify potential early predictors of unsatisfactory outcomes.METHODS: We conducted a retrospective cohort study of patients who underwent endoscopic balloon dilation for sympt
