From fertilizer to insecticide: urban leaf litter chemistry alters the survival landscape of Aedes aegypti

open access: yesPest Management Science, EarlyView.
Chemical profiling and bioassays reveal that leaf‐litter leachates from urban trees flip between nourishing and killing Aedes aegypti larvae: dilute Tipuana tipu boosts growth, whereas concentrated, aged extracts are >90% lethal. Species‐specific chemistry thus turns street trees into potential self‐renewing tools for integrated vector control ...

Pesticide exposure of operators during mixing and loading a drone: towards a stratified exposure assessment

open access: yesPest Management Science, EarlyView.
Operators are exposed to concentrated formulation during mixing of pesticide into the nurse tank and to an in‐use dilution during loading the drone; stratification of exposure for mixing and loading would inform the exposure assessment approach by applying the appropriate dermal absorption considerations.

Bridging Psychological Stress and Skin Cellular Aging: Flavonoids as a Dual‐Action Therapeutic Strategy

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Psychological stress (or simply “stress”) is a major contributor to chronic disease worldwide, affecting 35% of the global population, including younger generations. Furthermore, it plays a significant role in human premature aging; hence, its detrimental effects on people's health compel us to comprehend and control the ways in which ...

Turbulent snow transport and accumulation: New reduced‐order models and diagnostics

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Our new reduced‐order models of snow particle transport provide high‐fidelity calculations of snow accumulation in turbulent flows at significantly reduced computational costs. Additional accumulation diagnostics from the reduced‐order model predict complex patterns of particle concentration in turbulent boundary layers via coherent flow structures in ...

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 247-262., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

MODELING RUNOFF AND SEDIMENT YIELD OF KESEM DAM WATERSHED, AWASH BASIN, ETHIOPIA

open access: yes, 2015
Soil erosion, transport and deposition are a cause for reservoir sedimentation. Modelling runoff and sediment yield of watershed are the most important steps to alleviate reservoir sedimentation. This study mainly focused on modeling runoff and sediment yield of Kesem dam watershed using SWAT model.
