    A Systematic Review of Computational Fluid Dynamics Models in the Stomach and Small Intestine
    (MDPI (Basel, Switzerland), 2023-05-16) Palmada N; Hosseini S; Avci R; Cater JE; Suresh V; Cheng LK; Cappello F; Burgio S
    The use of in silico models to improve our understanding of the fluid dynamics within the gastrointestinal tract has increased over the last few decades. Computational fluid dynamics (CFD) is an in silico technique that can be used to characterize and model the fluid mechanics driving the digestion of food and absorption of nutrients. This systematic review outlines the current methodologies used to develop CFD models of the stomach and small intestine, and summarizes the flow and mixing patterns predicted from these models. A literature search was conducted on Scopus, and 15 stomach CFD studies and 15 small intestine CFD studies were included in this review after the literature selection and exclusion process. Two primary flow patterns; retropulsive flow and recirculation regions, were identified within the stomach CFD models. The flow patterns within the small intestine were depended on the type of motility pattern present. The shortcomings of the current models are discussed, and considerations for future gastric and intestinal flow modeling are provided.

    Breaking boundaries: Exploring gendered challenges and advancing equality for Iranian women careers in tourism
    (Elsevier Ltd, 2024-08-01) Carrasco-Santos MJ; Seyfi S; Hosseini S; Hall CM; Mohajer B; Almeida-García F; Cortes Macías R
    While there's growing interest in gender and employment issues in tourism studies, a gap exists when examining the obstacles women face in career pursuits, especially in theocratic societies. Drawing on Risman's gender structure theory, this qualitative study investigates how Iranian women perceive the impact of gender power dynamics on their careers and those of their peers. The findings reveal inhibitory factors affecting women's quest for equal career opportunities, including deeply ingrained societal influences on gender roles, institutionalized gender discrimination, and self-imposed constraints. The findings also demonstrate how gender stereotypes and theocratic structures manifest in the Iranian tourism industry, and how Iranian women working in the tourism sector actively negotiate, resist, and challenge these stereotypes to advance their careers. In a field where most gender-related studies originate from Western perspectives, this study holds particular significance in amplifying the voices of those in non-Western, theocratic societies.
