Measurement of Henry's law constants of ethyl nitrate in deionized water, synthetic sea salt solutions, and n-octanol.

Ethyl nitrate (EN; CHONO) is an important component of atmospheric "odd nitrogen" (NO) whose main source is marine emissions. To correctly describe its air-water transfer and model its global distribution, accurate values for its temperature- and salinity-dependent Henry's law solubility constants are needed. Here, we report Henry's law (H) constants for EN in deionized (DI) water, synthetic sea salt solutions (SSS), and n-octanol at temperatures between 278.

High-resolution characterization of short-term temporal variability in the taxonomic and resistome composition of wastewater influent.

Wastewater-based epidemiology (WBE) for population-level surveillance of antimicrobial resistance (AMR) is gaining significant traction, but the impact of wastewater sampling methods on results is unclear. In this study, we characterized taxonomic and resistome differences between single-timepoint-grab and 24 h composites of wastewater influent from a large UK-based wastewater treatment work [WWTW (population equivalent: 223 435)]. We autosampled hourly influent grab samples (=72) over three consecutive weekdays, and prepared additional 24 h composites (=3) from respective grabs.

Disposable nappies for preventing napkin dermatitis in infants.

Background: Napkin dermatitis is a common condition that occurs in otherwise healthy infants. It causes discomfort to infants, anxiety to parents and caregivers and contributes to the load on the health care system. A large variety of napkins, both disposable and non-disposable, are available.

Tubular spinae are long-distance connectors between bacteria.

The marine pseudomonad D71 (NCMB 2018) ['Spinomonas maritima'] can be induced to produce long tubular surface appendages (spinae) in a growth medium of low osmolarity. In general, spina-carrying cells show these appendages with open distal ends. We examined cultured cells by scanning and transmission electron microscopy, using both critical-point drying and thin sectioning after embedding with agarose protection.
