Factors affecting early plant survival in restoration of Mediterranean‐type climate shrublands

open access: yesConservation Science and Practice, EarlyView.
We undertook post‐fire restoration in southern California's shrubland with some portion of plants receiving supplemental irrigation. After 2.5 years survival was higher in California sage scrub (CSS) versus chaparral species and only slightly higher in irrigated individuals.

Time-dependent Scour Depth Under Bridge-submerged Flow [PDF]

open access: yes, 2010
Failure of bridges due to local scour has motivated many investigators to explore the reasons of scouring and to give the prediction of the scour depth. But most scour prediction equations only address non-pressure-flow situations.

The Effect of Mechanical Instrumentation on Dental Hard Tissue In Vitro: A Systematic Review

open access: yesInternational Journal of Dental Hygiene, EarlyView.
ABSTRACT Objective The aim of this review was to analyse the effects of hand instruments, ultrasonic scalers and air polishing devices on dental hard tissues, focusing on material loss and surface roughness. Methods Electronic databases MEDLINE, EMBASE, and the Cochrane Library were screened for relevant studies.

The Survival and Success of Teeth With External Cervical Resorption: A Multi‐Centre, Retrospective Study

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Objectives To evaluate the survival and success outcomes of teeth affected by external cervical resorption (ECR) managed using three distinct treatment strategies, with periapical radiographs and small field of view cone beam computed tomography used for diagnosis and treatment planning.

Maximum scour around cylinders induced by wave and current action [PDF]

open access: yes, 1986
The maximum possible scour around cylindrical structures under the action of combined wave and current was investigated in this study. A review of the literature showed that there are no adequate theories or methods for predicting maximum possible scour ...

Prediction of scour depth at breakwaters due to non-breaking waves using machine learning approaches [PDF]

open access: yes, 2017
Coastal structures may cease to function properly due to seabed scouring. Hence, prediction of the maximum scour depth is of great importance for the protection of these structures. Since scour is the result of a complicated interaction between structure,

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

open access: yesJournal 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.

Effect of buried plates on scour profiles downstream of hydraulic jump in open channels with horizontal and reverse bed slopes

open access: yesWater Science and Engineering, 2016
Local scour downstream of sluice gates in erosive beds is one of the main concerns of hydraulic engineers because it can cause considerable damage to structures.

Search for impact ejecta at the Paleocene–Eocene boundary

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Almost 10 years have passed since microtektites and microkrystites were reported for the Paleocene–Eocene (P–E) boundary in drill cores and outcrop in New Jersey and in ODP Hole 1051B in the western North Atlantic. The glassy spherules were interpreted to reflect an impact trigger for the Paleocene–Eocene Thermal Maximum (PETM).

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

open access: yesRestoration 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 ...
