A new brittleness index for estimation of rock fracture toughness

Assessment of the correlation between rock brittleness and rock fracture toughness has been the subject of extensive research works in the recent years. Unfortunately, the brittleness measurement methods have not yet been standardized, and rock fracture toughness cannot be estimated satisfactorily by the proposed indices. In the present study, statistical analyses are performed on some data col...

A metamorphic lesion.

uestion: A 65-year-old Caucasian woman presented at he emergency room with acute hematemesis. She reerred a short episode of oral bleeding 2 weeks before and omplained of solids nonprogressive dysphagia over the ast month. She was hemodynamically stable under inoropic support therapy, and a first endoscopic evaluation as performed (Figure A), where it was possible to idenify the bleeding origin...

A new approach for application of rock mass classification on rock slope stability assessment

The objective of this paper is to present a new rock mass classification system which can be appropriate for rock slope stability assessment. In this paper an evaluation model based on combining the Analytic Hierarchy Process (AHP) and the Fuzzy Delphi method (FDM)was presented for assessing slope rockmass quality estimates. This research treats the slope rockmass classification as a group deci...
