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.

Analysis of Air Cathode Perfomance for Lithium-Air Batteries [PDF]

open access: yes, 2013
Lithium-air (Li-air) batteries have a theoretical specific energy comparable to gasolines. The air cathode plays a critical role in battery operation, where oxygen reacts with Li ions and electrons; and discharge products are stored in the pore structure.

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

Familial retinal arteriolar tortuosity and quantification of vascular tortuosity using swept-source optical coherence tomography angiography

open access: yesAmerican Journal of Ophthalmology Case Reports, 2019
Purpose: Familial retinal arteriolar tortuosity (FRAT) is a rare autosomal dominant disorder that is characterized by tortuosity of the second and higher order retinal arterioles.

Ultrasonic wave propagation through porous ceramics at different angles of propagation [PDF]

open access: yes, 2014
The anisotropic pore structure and elasticity of cancellous bone cause wave speeds and attenuation in cancellous bone to vary with angle. Comparisons between predictions of a Biot-Allard model allowing for angle-dependent elasticity and angle-and ...

A review of the state of art in applying Biot theory to acoustic propagation through the bone [PDF]

open access: yes, 2014
Understanding the propagation of acoustic waves through a liquid-perfused porous solid framework such as cancellous bone is an important pre-requisite to improve the diagnosis of osteoporosis by ultrasound.

Quantifying Inactive Lithium in Lithium Metal Batteries [PDF]

open access: yes, 2019
Inactive lithium (Li) formation is the immediate cause of capacity loss and catastrophic failure of Li metal batteries. However, the chemical component and the atomic level structure of inactive Li have rarely been studied due to the lack of effective ...

Tortuosity of the descending thoracic aorta: Normal values by age.

open access: yesPLoS ONE, 2019
BackgroundAging changes the aorta in length, tortuosity and diameter. This is relevant in thoracic endovascular aortic repair (TEVAR) and in the long term follow up.Methods and resultsTwo groups of hundred patients < 65 years and hundred patients ≥ 65 ...

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.

Oxidative Stress Mediates Vascular Tortuosity [PDF]

open access: yesAntioxidants, 2021
Vascular tortuosity is associated with various disorders and is being increasingly detected through advances in imaging techniques. The underlying mechanisms for vascular tortuosity, however, remain unclear. Here, we tested the hypothesis that oxidative stress mediates the generation of tortuous vessels. We used the bilateral common carotid artery (CCA)
