Tectonic interpretation of the connectivity of a multiscale fracture system in limestone [PDF]

open access: yes, 2016
This paper studies the statistics and tectonism of a multiscale natural fracture system in limestone. The fracture network exhibits a self‐similar characteristic with a correlation between its power law length exponent a and fractal dimension D, i.e., a ≈

Discriminating cool-water from warm-water carbonates and their diagenetic environments using element geochemistry: the Oligocene Tikorangi Formation (Taranaki Basin) and the dolomite effect [PDF]

open access: yes, 2004
Fields portrayed within bivariate element plots have been used to distinguish between carbonates formed in warm- (tropical) water and cool- (temperate) water depositional settings.

Effects of Fire and Explosion Event in a Rural Area Fuel Depot Tank Farm: A Case Study From Istanbul, Türkiye

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Chemical facilities storing large volumes of flammable liquids close to residential areas pose severe fire‐and‐explosion hazards that can escalate into disasters. In this study, a tank farm located within Istanbul's city limits is examined to evaluate possible catastrophic scenarios using consequence analysis methods. For this purpose, several

A Geomechanical Study of the Mississippian Boone Formation [PDF]

open access: yes, 2013
The Boone Formation in northwest Arkansas is a chert-limestone sequence analogous to the subsurface Mississippi Lime reservoir in parts of Oklahoma and Kansas. It has low permeability and produces via horizontal drilling and hydraulic fracturing.

Comparing cranial biomechanics between Barbourofelis fricki and Smilodon fatalis: Is there a universal killing‐bite among saber‐toothed predators?

open access: yesThe Anatomical Record, EarlyView.
Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐

Characterizing groundwater flow and heat transport in fractured rock using Fiber-Optic Distributed Temperature Sensing [PDF]

open access: yes, 2013
International audienceWe show how fully distributed space-time measurements with Fiber-Optic Distributed Temperature Sensing (FO-DTS) can be used to investigate groundwater flow and heat transport in fractured media.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.
