The optimal shapes of piles in integral abutment bridges [PDF]
, 2017 Integral abutment bridges (IABs) can be used to avoid the durability issues associated with bearings and expansion joints. For this type of bridge, the design of the optimal pile foundation, especially with respect to the horizontal stiffness, is a ...

The Anatomical Record, EarlyView.Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Cyclic soil-structure interaction of integral railway bridges
Frontiers in Built EnvironmentIntegral bridges with larger spans experience increased cyclic interaction with their backfill, particularly due to seasonal temperature changes. This can result in a continuous increase of earth pressure (during the summer positions) as well as an ...

Effects of wall movements on performance of integral abutment bridges
, 2020 Abutment walls in integral abutment bridges (IABs) move in a cyclic pattern in response to temperature-induced expansion and/or contraction of the bridge superstructure.

7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia
Archaeology in Oceania, EarlyView.ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

Restoration of incisor area using one-piece implants: Evaluation of crestal bone resorption
Dental Research Journal, 2012 Background : One-piece implants (OPIs) incorporate the trans-mucosal abutment facing the soft tissues as an integral part of the implant. Since OPIs become more and more popular and no report specifically focuses on OPIs inserted in incisors′ area, a ...

Clinical Advances in Periodontics, EarlyView.Abstract Background Delayed wound healing following implant placement surgery is an uncommon complication, usually attributed to systemic (smoking and alcohol), local (severely inflamed tissues), or technical (poor suturing) factors. However, delayed wound healing after implant placement caused by severe hypovitaminosis C has not been previously ...

Seismic embankment-abutment-structure interaction of integral abutment bridges
, 2011 This research thesis is product of a joint study between the Ministry of Transportation and Infrastructure (BCMoT) and the University of British Columbia (UBC) to evaluate the effect of Embankment-Abutment-Structure Interaction (EASI) in the estimation of seismic demands of Integral Abutment Bridges (IABs).
