Search for supermassive magnetic monopoles using mica crystals [PDF]

open access: yes
The survival of the Galactic magnetic field almost certainly sets an astrophysical upper bound of approx. 10 to the minus 15th power cm(-2) sr(-1) s(-1) on the flux of monopoles.

Surgical Management of a High‐Grade Gastrointestinal Stromal Tumor in a Morbidly Obese Patient: A Case Study

open access: yesMedicine Advances, EarlyView.
This case study details the successful resection of a GEJ GIST in a high body mass index patient using an innovative surgical approach. Given the increasing prevalence of obesity, understanding and improving surgical approaches in these patients becomes paramount in preventing surgical morbidity. ABSTRACT Gastrointestinal stromal tumors (GISTs) are the

Numerical Modelling of Frictional Sliding Induced Damage and Heating Effects on Rock With an Application to Sievers’ J‐Miniature Drilling on Granite

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The present study develops a finite element‐based numerical method for simulation of frictional rotational sliding induced damage and heating effects on rock. The method is applied to the Sievers’ J‐ miniature drill test, which is widely used for estimating the rock drillability and predicting the cutter life.

Structural and Material Properties of Chitin Nanofibers Produced Without Deacetylation Treatment

open access: yesNano Select, EarlyView.
In this study, we prepared chitin nanofibers with a width of several nanometers without the need for a deacetylation process. We examined their structural properties, such as their morphology, surface charge, colloidal stability, and material performance, including their emulsifying capabilities and film properties, by comparing them with those of ...

Atomic Force Microscopy of Emulsions and Their Interfacial Nanoparticles

open access: yesNatural Sciences, EarlyView.
Emulsion droplets and their interfacial nanoparticles were imaged under water by atomic force microscopy. Changes in the sample were triggered by increasing the applied mechanical force. Mechanical data was overlaid on the topography data for an improved understanding of the properties and behavior of the droplets and particles.
