The beginnings of geography teaching and research in the University of Glasgow: the impact of J.W. Gregory [PDF]

, 2009
J.W. Gregory arrived in Glasgow from Melbourne in 1904 to take up the post of foundation Professor of Geology in the University of Glasgow. Soon after his arrival in Glasgow he began to push for the setting up of teaching in Geography in Glasgow, which ...

Synergistic Physicochemical Inhibition of Reactive Shale Formations Using Hydrothermally Synthesized Hydroxyapatite Nickel Tungstate Nanocomposites in Water‐Based Drilling Fluids

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wellbore instability driven by the volumetric expansion of reactive shale formations remains a primary operational challenge in modern drilling engineering, causing severe mechanical failures and substantial economic deficits. The objective of this study is to formulate and evaluate a novel dual‐action chemical additive capable of ...

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Normal faulting in the Pathé geothermal area, Central Mexico [PDF]

Geofísica Internacional, 1998
The Pathé geothermal area is located in Late Miocene to Pliocene volcanic rocks in a region of active normal faulting. These faults cluster in sets striking near E-W and close to N-S.

Structural heterogeneity and permeability in faulted eolian sandstone: Implications for subsurface modeling of faults [PDF]

, 2002
We determined the structure and permeability variations of a 4 km-long normal fault by integrating surface mapping with data from five boreholes drilled through the fault (borehole to tens of meters scale).

Present-day stress orientations and tectonic provinces of the NW Borneo collisional margin [PDF]

, 2010
Extent: 15p.Borehole failure observed on image and dipmeter logs from 55 petroleum wells across the NW Borneo collisional margin were used to determine maximum horizontal stress (σH) orientations; combined with seismic and outcrop data, they define seven

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Identification of Natural and Forcing Frequencies through Noisy Measurements Acquired in Operational Conditions on a Hospital Building

Advances in Civil Engineering
Operational modal analysis is a robust and practical approach to structural health monitoring which assumes white noise as input. Therefore, the accuracy of this method can be compromised when dealing with colored unknown excitations, in which, for ...

Thick-Skinned and Thin-Skinned Tectonics: A Global Perspective

Geosciences, 2017
This paper gives an overview of the large-scale tectonic styles encountered in orogens worldwide. Thin-skinned and thick-skinned tectonics represent two end member styles recognized in mountain ranges.
