Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Shaping Manager Well‐Being and Functioning in Declining Nonprofit Organizations: The Critical Role of Strategy Implementation

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT Under the roof of Christian churches in Central Europe, some nonprofit organizations (NPOs) grow, while others are in marked decline. Our study in this context extends a previous focus on financial indicators to NPO managers' experiences, their role clarity and job satisfaction, during phases of organizational growth and decline. Specifically,

Clinical periodontal diagnosis

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...

Development of Cost‐Effective and Highly Transparent Melamine Formaldehyde Resin Modified With Sodium Chloride for Enhancing Glossiness and Abrasion Resistance of Melamine Impregnated Paper

open access: yesPolymer Engineering &Science, EarlyView.
An eco‐friendly melamine‐formaldehyde was produced by the addition of sodium chloride as a modifier. Modified MF resin improved surface gloss and abrasion resistance of decorative paper and decreased the formaldehyde emission. Curing time of the MF resin decreased with the addition of sodium chloride.

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

open access: yesSustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.
