Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

open access: yesStructural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Taking Stock: Elite Studies and Social Change

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT This article provides a systematic synthesis of contemporary elite sociology through the analytical lens of change and stability. We distinguish between two types of change: change within elites, referring to transformations in elite composition, circulation, or internal characteristics; and change by elites, designating processes whereby ...

Multilinear Regression–Based Rock Physics Template Modeling for Sandstone Reservoir Characterization

open access: yesScientific Contributions Oil and Gas
Rock Physics Templates (RPT) are widely used to link petrophysical parameters with elastic properties for fluid identification in reservoir characterization. Previous studies have demonstrated the potential of RPT for fluid detection method; however, well-defined procedures for determining rock matrix parameters and P-wave velocity (Vp) as the basis ...
