Crack density tensor inversion for analysis of changes in rock frame architecture

This paper presents a development of the use of multi-axial ultrasonic data for the quantification of extrinsic, crack or grain-contact induced elastic anisotropy in core samples with application to a UKCS oil field. An approach for inversion of multi-axial velocity measurements is presented, which extends the previous work by Sayers (2002) for the determination of second- and fourth-order crack d

Ergative case in the Circassian languages

The Circassian languages (Northwest Caucasian) exhibit ergative patterns both in case marking and in the alignment of agreement markers in the verb. Ergative/absolutive case marking is restricted to certain types of nominals, which thus results in split-ergativity. The paper examines the marking of ergative/absolutive case in various types of nominals and relates the distribution to the Nominal Hi

The Unsustainable European Policy towards the South Caucasus

The article reviews the unsustainable appeasement policy of Europe towards South Caucasus, especially Armenia and Azerbaijan in regard to the unresolved conflict of Nagorno-Karabakh. Unless a policy shift is implemented by all involved parties, a possible re-eruption of the armed conflict, with disastrous consequences, is feared.
