Prediction of free bowel perforation in patients with intestinal Behçet's disease using clinical and colonoscopic findings.

open access: yes, 2010
BACKGROUND: Gastrointestinal tract involvement in Behçet's disease (BD) often requires surgical intervention due to serious complications such as intestinal perforation, fistula formation, or massive bleeding.

Integral Experiments and Magnetic Resonance Imaging of Lab‐Scale Liquid Distributors

open access: yesChemie Ingenieur Technik, EarlyView.
Four lab‐scale liquid distributors were evaluated based on the homogeneity of the resulting liquid distribution. The best‐performing design reduced maldistribution and wall flow compared to a single‐point liquid distribution and remained stable under varying operating conditions, including different gas and liquid loads.

INTESTINAL PERFORATION DUE TO PHYTOBEZOAR OBSTRUCTION

open access: yes, 1993
Phytobezoars are rare causes of acute abdomen cases. Here we are reporting two cases which were presented with acute abdomen symptoms and latere were found to be small intestinal perforation due to ...

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Front Propagation Through a Perforated Wall

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We consider a bistable reaction– diffusion equation ut=Δu+f(u)$u_t=\Delta u +f(u)$ on RN${\mathbb {R}}^N$ in the presence of an obstacle K$K$, which is a wall of infinite span with many holes. More precisely, K$K$ is a closed subset of RN${\mathbb {R}}^N$ with smooth boundary such that its projection onto the x1$x_1$‐axis is bounded and that ...

Geological carbon dioxide storage in the German North Sea: Static‐to‐dynamic capacity refinement for a 10 Mt/y injection scenario

open access: yesDeep Underground Science and Engineering, EarlyView.
This study assesses whether a saline aquifer in the German North Sea can sustain industrial‐scale CO2 injection at 10 Mt/year over 30 years. A 3D reservoir model is used to compare static capacity with dynamically achievable storage. The work links site‐scale injection strategy design with basin‐scale pressure response, providing a framework for ...

Recent Advances in Pickering Emulsion Templated Phase Change Material Microcapsules: Design, Fabrication, and Multifunctional Applications

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fabrication process of phase change microcapsules using a Pickering emulsion template method and their subsequent applications. The increasing demand for efficient thermal energy storage systems has driven the development of phase change material microcapsules (PCMMs), which provide high energy‐storage density, reversible phase change, and reduced ...

Perforation of the terminal ileum caused by brucellosis: A case report

open access: yesClinical Case Reports
Key Clinical Message Brucellosis, caused by gram‐negative coccobacilli of the genus Brucella, is a zoonotic disease with bone and joint complications being common. However, acute abdomen with intestinal perforation is rare. We present a case of a 69‐year‐

Sacrificing Energy for Mass Transfer to Boost Solar Steam Generation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Vapor accumulation often limits the performance of passive interfacial solar evaporation. Inspired by the Dyson sphere concept, Xu, Yang, and co‐workers designed a perforated‐shell evaporator with an internal non‐evaporating core that diverts incident sunlight to drive self‐generated internal convection for vapor removal.

Artificial Intelligence in Ophthalmology: From Methodological Advances to Clinical Translation and Future Directions

open access: yesEye &ENT Research, EarlyView.
ABSTRACT Artificial intelligence (AI) is reshaping ophthalmology from task‐specific image analysis toward multimodal, longitudinal, and clinically integrated decision support. This narrative review summarizes the methodological evolution of ophthalmic AI, including traditional machine learning, task‐specific deep learning, self‐supervised learning ...
