Early Endoscopic Repair of Traumatic Skull Base Dural Injuries: Challenging the Dogma of Conservative Management

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Traditional management of traumatic skull base dural injury has often favored observation and conservative therapy, despite the risk of delayed intracranial complications. This paradigm originated when operative intervention required craniotomy and carried significant morbidity.

Study on pre-splitting blasting technology of hard roof face

open access: yesIOP Conference Series: Earth and Environmental Science, 2019
Abstract In order to solve the problems of hard roof caving and overhanging area in 220116 working face of Xinji No.2 Coal Mine, deep-hole pre-splitting blasting overburden technology is adopted to destroy the integrity of roof in advance so as to make it collapse as soon as possible, reduce the apparent strength of rock pressure of ...

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Mechanism of grouped collapse of thick and hard roof for gob-side entry retaining combined backfill in fully-mechanized caving face

open access: yesMeitan xuebao
A large range of caving roof of gob-side entry retaining is easy to cause impact damage of the roadside backfill body. In order to ensure the stability of gob-side entry retaining, different from the traditional large-angle inclined roof cutting method ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,
