Repair Bond Strength of Self‐Cure Bulk‐Fill Composites: Influence of Substrate Composition, Surface Conditioning, and Repair Material Type

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study aimed to evaluate the effects of substrate composition, surface conditioning protocol, and repair material type on the repair shear bond strength (SBS) of an aged self‐cure bulk‐fill resin composite. Materials and Methods A total of 80 specimens were fabricated using two substrate compositions of a self‐cure bulk ...

Experimental investigation of the effect of the presence of obstacles at the end of the output keys of the C-type piano key weir on its downstream scour [PDF]

علوم آب و خاک
Piano key weirs are a type of non-linear weir that have a higher discharge coefficient than similar linear weirs. These hydraulic structures have a lightweight foundation and a simple structure is designed and installed on dams and drainage channels. Due

Prediction of scour profiles downstream of grade control structures via the shear stress and sediment bed curvature model

International Journal of Sediment Research
A new semianalytical model for the prediction of local scour profiles downstream from typical grade-control structures is proposed on the basis of the variation in bed shear stress and the sediment bed curvature concept.

Shark preferences: Only subtle effects of electromagnetic field exposure and substrate type on small‐spotted catshark (Scyliorhinus canicula) behaviour

Journal of Fish Biology, EarlyView.
Abstract Offshore wind energy plays a crucial role in the transition to low‐carbon power generation. The expansion of offshore wind farms (OWFs) introduces anthropogenic electromagnetic fields (EMFs) from subsea power cables. Elasmobranchs, including sharks and rays, are sensitive to natural electric and magnetic fields used for navigation and prey ...

Impact of the invasive diatom species Cymbella janischii on riverine microbial biofilm communities and a potential role of bacterially produced zeatin

Journal of Phycology, EarlyView.
Abstract The diatom Cymbella janischii is an invasive species in Japan, causing nuisance blooms by forming thick mats in rivers. To date, there are no documented studies on the microbiome associations in C. janischii mats or the processes that drive bloom formation.

Influence of propeller clearance on the jet scour process in restricted water

International Journal of Sediment Research
Rapid development of inland waterways and marine transportation has resulted in the construction of large ships and an increase in ship speed. Consequently, severe local scour erosion of restricted water beds occurs due to propellers, endangering the ...

Field‐based evaluation of glass cullet as a supplementary sediment source for coastal restoration

Restoration Ecology, EarlyView.
There is an ever‐increasing demand for sand to support projects like beach nourishment and dune restoration, but dredging and mining sand causes environmental damage. Demonstrating the environmental and ecological compatibility of crushed and ground glass known as cullet to support coastal restoration projects could simultaneously divert waste from ...

Disturbance legacies in arid environments shape recovery of former agricultural land

Restoration Ecology, EarlyView.
Abstract Introduction Increasingly, arid agricultural land is being permanently taken out of irrigated production due to more frequent drought, higher temperatures, and the overconsumption of groundwater, with important ramifications for ecological recovery.

Limited effects of structural restoration on ecosystem functioning in an urban tropical stream

Restoration Ecology, EarlyView.
Abstract Introduction Hydromorphological restoration through structural interventions is commonly used to mitigate urbanization impacts on lotic freshwater systems, but their effects on ecosystem functioning in urban tropical streams remain unexplored.

Spatial and temporal evolution of a coastal erg margin: the Middle Jurassic Page Sandstone, southern Utah, USA

Sedimentology, EarlyView.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...
