New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Restoration of incisor area using one-piece implants: Evaluation of crestal bone resorption

open access: yesDental 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 ...

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

open access: yesThe Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Cyclic soil-structure interaction of integral railway bridges

open access: yesFrontiers in Built Environment
Integral 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 ...

Variable length strut with longitudinal compliance and locking capability [PDF]

open access: yes, 1985
A variable length strut device is illustrated for connecting two associated structures which includes an outer load bearing shell, a drive assembly, a length varying compliance assembly positioned by drive assembly, and a strut rod locking assembly.

Cubical and cosimplicial descent [PDF]

open access: yes, 2017
We prove that algebraic K-theory, topological Hochschild homology and topological cyclic homology satisfy cubical and cosimplicial descent at connective structured ring spectra along 1-connected maps of such ring ...

Girder’s Response under Integral Abutment Bridge

open access: yesIOP Conference Series: Earth and Environmental Science
Abstract From the past evaluation and trend in bridge engineering Integral abutment bridges are gaining more popularity than conventional bridges. Kalkaji Flyover Delhi is one of the recent examples of five span continuous deck IAB. Girders are directly joined with abutment/piers without any bearings.

Composite Bridges with Integral Abutments Minimizing Lifetime Cost

open access: yesIABSE Symposium, Melbourne 2002: Towards a Better Built Environment - Innovation, Sustainability, Information Technology, 2002
The cost of maintenance is an ever- growing problem for road administrations around the world, and bridges are no exception to the rule.

Cranial anatomy of a Late Cretaceous aspidorhynchid fish (Neopterygii: Aspidorhynchiformes) from Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.

Effectiveness of one-piece implants inserted in cuspid sites

open access: yesDental Research Journal, 2012
Background: One-piece implants (OPIs) incorporate the trans-mucosal abutment facing the soft tissues as an integral part of the implant. OPIs are usually welded together and loaded immediately.
