Environmental controls on the distribution of neoselachian sharks and rays within the British Bathonian (Middle Jurassic). [PDF]

open access: yes, 2003
Extensive sampling from a range of facies within the Bathonian (Middle Jurassic) of southern England has allowed the palaeoenvironmental distribution of a number of taxa of neoselachian sharks and rays to be assessed.

METHODS AND TECHNIQUES USED FOR ESTABLISHING THE AGE AND GENESIS OF PELITIC ROCKS. APPLICATIONS IN GEOGRAPHY [PDF]

open access: yesAnalele Universității din Craiova. Seria Geografie, 2009
In the sedimentary domain, clays represent about half of the detritic rocks in terms of frequency. Clasts with the diameters smaller than 2 or 4μm, according to the used scale, clays, also called pelitic rocks, have to contain as deposits more than 60 ...

Geophysical assessment of subsurface conditions at proposed building sites: implications for foundation failure and building collapse [PDF]

open access: yes, 2018
Building collapse has been a recurrent environmental hazard in Nigeria in the last two decades. This is a corollary of inadequate foundation investigation prior to construction, poor government policies, and general lack of awareness on the importance of
