Theoretical Model of Transient Regression of Thermoplastic Materials During Flame Spread: Vaporization; Permanent Mass Loss; Surface Shape

Fire and Materials, EarlyView.
ABSTRACT This article examines a transient, one‐dimensional model of surface regression during opposed flow flame spread over finite thickness, non‐charring thermoplastics. Gas to solid conductive transfer from the flame drives sample heating. The solid degrades into volatile fuel molecules in two stages: (1) the pre‐vaporization heat‐up stage and (2 ...

Lifetime of the Gas Evolution Electrode of the Zn–H2 Storage System

Fuel Cells, EarlyView.
ABSTRACT A novel electrically chargeable galvanic system is presented that efficiently stores energy in the form of zinc and releases hydrogen and electricity upon discharge. In this concept, oxygen is released at the gas electrode during charging, and zinc oxide is reduced to metallic zinc at the counter electrode.

Future Range Shifts and Diversity Patterns of Antarctic Lecideoid Lichens Under Climate Change Scenarios

Global Change Biology Communications, EarlyView.
Modeling of current and future spatial distribution of Antarctic lecideoid lichens shows that warming will strongly increase the potential habitat. Under three climate‐change scenarios, most fungal and algal partners are projected to expand inland. Overall, climate change drives widespread range shifts and promotes colonization of interior Antarctica ...

Algal Blooms in Lakes Increase After Wildfire Smoke Events in the Contiguous United States

Global Change Biology Communications, EarlyView.
Temporary pulses of surface chlorophyll‐a are identified following wildfire smoke events in lakes and reservoirs across the United States. ABSTRACT Area burned by wildfire has increased in the contiguous United States and in many places globally in recent years, impacting communities and ecosystems nearby and even far downwind of fires. We examined the

Efficacy of energy‐based devices on episiotomy pain and healing: A systematic review and meta‐analysis

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Episiotomy is a common obstetric procedure often associated with significant postpartum pain and delayed wound healing. Conventional treatments provide limited relief and might not be suitable for all women. Energy‐based therapies, including infrared irradiation and low‐level laser therapy (LLLT), a non‐thermal photo biomodulation ...

Adult Advisor Efficacy to Support LGBTQ+ Youth as a Predictor of LGBTQ+ Youth's Experiences in Gender‐Sexuality Alliances (GSAs) and at School

Journal of Adolescence, EarlyView.
ABSTRACT Introduction Many LGBTQ+ youth seek support from adults at school, which can include advisors of Gender‐Sexuality Alliances (GSAs; clubs affirming LGBTQ+ youth). Little research has considered how efficacious advisors feel to support LGBTQ+ GSA members, or how advisors' efficacy contributes to LGBTQ+ youth's school experiences.
