Environmental Policy and the Macroeconomy in the Presence of Ecological Thresholds [PDF]

We study the environmental and economic effects of public abatement in the presence of multiple stable steady-state ecological equilibria. Under shallow-lake dynamics (SLD), the isocline for the stock of pollution features two stable branches, a good and

Palatal donor site wound healing following mucogingival surgery using amnion‐chorion membrane: A randomized controlled clinical trial

Journal of Periodontology, EarlyView.
Abstract Background Free soft tissue autografts (FSTA) harvested from a patient's palate are frequently associated with significant postoperative morbidity. Several wound dressings have been applied to the palatal donor site with the aim of reducing postoperative complications and improving wound healing.

Use of ultrasonography in assessing peri‐implant osseous defects: An in vitro study

Journal of Periodontology, EarlyView.
Abstract Background The purpose of this study is to investigate the feasibility and diagnostic accuracy of ultrasonography in peri‐implant defect identification and evaluation, and to compare ultrasonography (USG) with cone‐beam computed tomography (CBCT) in defect identification and evaluation in an in vitro model.

Shallow sub-lakes are essential for sustaining the successful wintering of waterbirds in Poyang Lake, China

Avian Research
For migratory waterbirds, the quality of wintering habitat is related to spring migration and successful breeding in the next year. The availability of food resources in the habitat is critical and varies within water levels.

From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone

Journal of Quaternary Science, EarlyView.
ABSTRACT The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain.
