Virus inactivation and skin safety studies using far‐UVC LEDs

open access: yesPhotochemistry and Photobiology, EarlyView.
This study uses an LED exposure system with a peak output at 233 nm to examine efficacy for inactivation of human coronavirus as well as potential health hazards for human exposure. Abstract Reducing airborne disease transmission is a public health goal.

Germicidal potential and skin compatibility of an innovative UVC phototherapy device emitting at 234 nm

open access: yesPhotochemistry and Photobiology, EarlyView.
A phototherapy device emitting principally at 234 nm was assessed for antimicrobial efficacy against Methicillin‐resistant Staphylococcus aureus and evaluated for skin health hazards. Abstract Chronic wounds are a major healthcare issue affecting more than 10 million Americans each year, with a 5‐year survival similar to cancer and costing the ...

Recurrent hot droughts cause persistent legacy effects in a temperate Scots Pine forest

open access: yesPlant Biology, EarlyView.
A series of hot drought events caused persistent legacy effects in a Scots Pine forest, with severe negative impacts on ecosystem carbon fluxes. Abstract Recent hot‐dry events have caused significant impacts and legacy effects in temperate ecosystems. Here, we investigate legacy effects of the 2018 hot drought on a Pinus sylvestris L.

Modeling energy flow and nutrient cycling in natural semiarid grassland ecosystems with the aid of thematic mapper data [PDF]

open access: yes
Energy flow and nutrient cycling were modeled as affected by herbivory on selected intensive sites along gradients of precipitation and soils, validating the model output by monitoring selected parameters with data derived from the Thematic Mapper (TM ...

No legacy effects of severe drought on carbon and water fluxes in a Mediterranean oak forest

open access: yesPlant Biology, EarlyView.
A Mediterranean Quercus ilex forest was severely affected by a drought in 2017 but fully recovered in the following year, supported by favourable weather and growing conditions both before and after the event. Abstract Severe droughts affect vegetation through several processes, such as hydraulic failure, early leaf senescence, depletion of carbon ...
