Machine learning prediction of tortuosity in digital rock

open access: yesJGEET: Journal of Geoscience, Engineering, Environment and Technology, 2023
Physical rock property measurement is an important stage in energy exploration, both for hydrocarbons and geothermal sources. The value of physical rock properties can provide information about reservoir quality, and one of these properties is tortuosity.

Relationship between coronary tortuosity and plateletcrit coronary tortuosity and plateletcrit [PDF]

open access: yesCardiovascular Journal of Africa, 2017
Coronary tortuosity (CorT) is a common angiographic finding and may be associated with myocardial ischaemia, even without coronary artery disease. Platelets play a crucial role in inflammatory and thrombotic processes and the physiopathology of cardiovascular disease.

Tortuosity of Tight Rocks [PDF]

open access: yes, 2022
Tortuosity is a rock property that controls transport processes in porous media. It is essential in advective, diffusive transport and flow of electric current, especially in tight rocks which are characterized by low porosity and low permeability such ...

A case of distal limb arterial tortuosity and dilation: observations and potential clinical significance

open access: yesFolia Morphologica, 2022
Arterial tortuosity describes variation via bending of the arterial wall and has been noted in several arteries throughout the body. Tortuous blood vessels can cause nerve compression, as well as present difficulties to surgeons and radiologists. Here we

Accuracy of vascular tortuosity measures using computational modelling

open access: yesScientific Reports, 2022
Severe coronary tortuosity has previously been linked to low shear stresses at the luminal surface, yet this relationship is not fully understood. Several previous studies considered different tortuosity metrics when exploring its impact of on the wall ...

Retinal arteriole tortuosity changes over time in a veteran population with diabetes

open access: yesDiabetes Epidemiology and Management, 2022
Purpose: Arteriole tortuosity is an important sign of retinal disease which is associated with diabetic retinopathy, but it is unclear how arteriole tortuosity changes over time in populations with diabetes. It has been suggested that retinal vasculature

Wave propagation in stereo-lithographical (STL) bone replicas at oblique incidence [PDF]

open access: yes, 2011
Comparisons between predictions of a Biot-Allard model allowing for angle-dependent elasticity and angle-and-porosity dependent tortuosity and transmission data obtained at normal incidence on water-saturated replica bones are extended to oblique ...
