Biofilm removal capacity and titanium surface integrity in non‐abrasive versus abrasive peri‐implantitis cleaning interventions

Journal of Periodontology, EarlyView.
Abstract Background Current peri‐implantitis treatment methods are modeled after dental cleaning modalities like abrasive surface cleaning. However, mechanical abrasive cleaning not only inadequately removes implant biofilms but also compromises implant surface integrity with adverse biological effects.

Hydraulic erosion patterns downstream of corrugated aprons: investigating free and submerged jet effects

Frontiers in Environmental Engineering
The experimental evaluation of the performance of a corrugated apron under free flow subcritical and submerged conditions was conducted, with a focus on scour patterns over the apron. Comparative analysis with a smooth rigid apron revealed an increase in

Experimental Investigation of the Effects of Flow Discharge on the Scour Rate around the Groups of Bridge Piers with a Rough Surface in the Presence of Aggregate Extraction Pits

علوم آب و خاک, 2021
The scour around the bridge piers is one of the main causes of bridge failure and the extraction of aggregates may aggravate this phenomenon. The present study comprehensively investigated the scour around the groups of bridge piers in the presence of ...

Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

Journal of Quaternary Science, EarlyView.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

The anatomy of exhumed river-channel belts: Bedform to belt‐scale river kinematics of the Ruby Ranch Member, Cretaceous Cedar Mountain Formation, Utah, USA [PDF]

, 2020
Many published interpretations of ancient fluvial systems have relied on observations of extensive outcrops of thick successions. This paper, in contrast, demonstrates that a regional understanding of palaeoriver kinematics, depositional setting and ...

Influence of junction angle on three-dimensional flow structure and bed morphology at confluent meander bends during different hydrological conditions [PDF]

, 2014
© 2014 John Wiley & Sons, Ltd. Recent field and modeling investigations have examined the fluvial dynamics of confluent meander bends where a straight tributary channel enters a meandering river at the apex of a bend with a 90° junction angle.

Wild pig habitat use impacted by prescribed fire in the William B. Bankhead National Forest, USA

The Journal of Wildlife Management, EarlyView.
Natural resource management activities like integrated wild pig control programs and 3–5‐year interval prescribed burning can reduce wild pig activity and habitat but can have an unintended side effect of allowing them to thrive in sensitive and protected areas, where access and tools are restricted.

Investigation of Scour Depth Downstream of Stilling Basin for the Case of B-Jump [PDF]

علوم و مهندسی آبیاری, 2016
Scour downstream of hydraulic jump stilling basins can damage the surrounding area and can cause failure of the structure itself. Because of the study of such phenomenon has attracted the attention of researchers in the past.
