This paper presents a new model for predicting the fluid flow through a Marsh funnel. Based on Herschel-Bulkley fluid model, the model considers both the friction force and the dynamic force. Pressure drop due to the yield stress in the conical section is accounted in the model. In addition, an improved testing system is proposed for the validation...

The effects of apparent wall slip on rheometric measurements of waxy gels are quantified for gels consisting of a macrocrystalline wax added in mineral oil in concentrations of 3.0 and 7.5 wt. %. The waxy gels are formed in situ in a stress-controlled rheometer, and rheological properties are then obtained. Seven different geometry configurations, ...

Colloidal aggregation is quantitatively characterized by a rheological analysis of the colloidal suspension at various particle concentrations. The rheological analysis is combined with fractal concept to estimate the compactness, size, and size variation with shear stress on colloidal aggregates. The rheological measurement is carried out for a co...

Even today, breast cancer remains a global public problem, with a high mortality rate among women. Nanoparticle (NP) based systems are developed to enhance drug delivery, reducing the toxic effect of medicine molecules. By using iron oxide nanoparticles for cancer treatment, several advantages were highlighted: the ability to target specific locati...

The 3D printing of concrete has now entered a new era and a transformation of the construction sector is expected to reshape fabrication with concrete. This work focuses on the selective paste intrusion method, which consists of bonding dry particles of aggregate with a cement paste. This innovative technique could lead to the production of very pr...
Medication lubricants are thick liquids or gels that are designed to aid swallowing of solid oral dosage forms. Tablets and capsules are placed within a spoonful of the product for swallowing. The aim of this study was to describe and compare commercially available medication lubricants in terms of textural suitability for patients with dysphagia. ...

Lithospheric yield stress is a key parameter in controlling tectonic processes. Using high resolution, 2D numerical modeling, we calculate the yield stress for a range of conditions appropriate to the early-to-mid Archean Earth, including hotter mantle potential temperatures and Moho temperatures. We then evaluate its effect on generating tonalite-...
Drobirski tokovi spadajo med izjemno hitre pobočne masne premike, ki se navadno prožijo v hribovitih in gorskih območjih. Veljajo za izredno kompleksen naravni pojav, katerega je težko napovedati. Za razliko od drugih vrst zemeljskih plazov, drobirski tokovi lahko prepotujejo velike razdalje. Zaradi velikih hitrostih gibanja evakuacija ob njihovi s...
