The Natural Fracture of Flint [PDF]

open access: yesNature, 1912
SIR E. RAY LANKESTER, K.C.B., in his learned and comprehensive article in NATURE of November 21, has suggested the various lines of research which it will be necessary to follow if a thorough-going knowledge of the mode of origin, structure, and fracture of flint is to be obtained.

Temporary brittle bone disease:association with intracranial bleeding [PDF]

open access: yes, 2013
We report 20 infants aged between 1 month and 6 months found to have subdural bleeding and also multiple unexplained fractures in a pattern similar to that described earlier as temporary brittle bone disease. Child abuse seemed unlikely as a cause of the

Numerical study failure characteristics of natural fracture under induced stress

open access: yesEnergy Reports, 2023
Hydraulic fracturing is an effective method for developing oil and gas in unconventional reservoirs. The openings of natural fractures directly affect the complexity of the fracture body.

Role of natural fractures in damage evolution around tunnel excavation in fractured rocks [PDF]

open access: yes, 2017
This paper studies the role of pre-existing fractures in the damage evolution around tunnel excavation in fractured rocks. The length distribution of natural fractures can be described by a power law model, whose exponent a defines the relative ...

Water Intrusion Characterization in Naturally Fractured Gas Reservoir Based on Spatial DFN Connectivity Analysis

open access: yesEnergies, 2020
In this study, the non-intrusive embedded discrete fracture model (EDFM) in combination with the Oda method are employed to characterize natural fracture networks fast and accurately, by identifying the dominant water flow paths through spatial ...

Proximal humeral fractures with a severe varus deformity treated by fixation with a locking plate

open access: yes, 2010
We treated 47 patients with a mean age of 57 years (22 to 88) who had a proximal humeral fracture in which there was a severe varus deformity, using a standard operative protocol of anatomical reduction, fixation with a locking plate and supplementation ...

Quantitative Prediction of Natural Fractures in Shale Oil Reservoirs

open access: yes, 2021
Natural fractures are the key factors controlling the enrichment of shale oil. It is of great significance to clarify the distribution of natural fractures to guide the selection of sweet spots for shale oil.

Development characteristics of natural fractures in tight sandstone reservoirs and their controlling factors: upper Triassic Xujiahe Formation, western Sichuan Basin

open access: yesFrontiers in Earth Science
Natural fractures are widely developed and distributed in tight sandstone reservoirs in the western Sichuan Basin, China, influenced by complex tectonic movements and diagenetic processes.
