Submerged geomorphic record of Quaternary palaeoshorelines: terraces and clinothems along a shelf‐edge in the Žirje Archipelago, Adriatic Sea

open access: yesBoreas, EarlyView.
Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

Characteristics of the Wall Pressure in Impacting Zone at the End of Vertical Plug

open access: yes工程科学与技术, 2019
The vertical plug is a new way to dissipate water energy, in which the flow can be regarded as a submerged jet, and the construction leads to the high velocity and pressure on the wall.

Movement characteristics of coal powders at bottom of coalbed methane well under jet flow

open access: yesEnergy Science & Engineering
The removal and discharge of coal powders from coalbed methane wellbore is the key to maintaining continuous production. For this reason, based on the submerged jet theory, the force and migration starting conditions of coal powder particles deposited at

Assessing responses of reef island seabirds to environmental and anthropogenic drivers

open access: yesConservation Biology, EarlyView.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Using Long‐Term Monitoring Data to Assess Temporal Patterns in Fish Community Assemblages in Florida Lakes

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT In an effort to increase the relevancy of fish community data for management, we used fish community data to conduct a statewide assessment of Florida's freshwater fisheries resources and compare the relationships between environmental factors and freshwater fish communities over time.

Exploring the Impact of Ultrasonic Activation on the Antimicrobial Activity of Root Canal Sealers: A Year‐Long Ex Vivo Investigation Into Bacterial Survival

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim This study investigated the long‐term survival of bacteria in root canals obturated using two endodontic sealers—AH Plus Jet (AHP) and BioRoot RCS (BCS)—while also assessing the influence of ultrasonic agitation on their antimicrobial effectiveness.

Mechanical and Metallurgical Evaluation of Four Rotary Nickel‐Titanium File Systems: A Multimethod Study

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim To compare four rotary nickel‐titanium (NiTi) file systems (Endostar E3 Azure, Endostar E3, VDW.ROTATE, and Mtwo) using a multimethod approach to evaluate their mechanical and metallurgical properties. Materials and Methods Endostar E3 Azure, Endostar E3, VDW.ROTATE, and Mtwo (all size 25/0.06 with an S‐shaped cross‐section; 52 instruments

Soft Tissue Volume Augmentation at Single Implant Sites Applying Collagen Matrices or Connective Tissue Grafts: 10‐Year Follow‐Up of a Randomized Controlled Trial

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Aim To compare up to 10 years clinical, profilometric and patient‐reported outcomes of implant sites previously augmented using a volume‐stable collagen matrix (VCMX) or connective tissue graft (SCTG) in the aesthetic zone. Methods The original non‐inferiority randomized controlled trial (RCT) enrolled 20 patients who received soft tissue ...

The roads most traveled: genetic convergence in plant repeated evolution

open access: yesNew Phytologist, EarlyView.
Observation of a genotype–phenotype association in a focal lineage (magnifying lens) provides a starting point for predicting homolog reuse during repeated trait evolution. This review suggests that the likelihood that mutations in homologous genes contribute to similar phenotypes in other lineages depends on both mutational effect stability (MES) and ...

Long‐term periodontal and peri‐implant tissue stability under supportive therapy

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Supportive periodontal and peri‐implant maintenance therapy is strongly associated with improved long‐term retention and stability of natural teeth and dental implants. Lack of regular professional follow‐up after initial therapy is a major risk factor for disease recurrence and tooth or implant loss.
