Trapped in the web of water: Groundwater‐fed springs are island‐like ecosystems for the meiofauna

We investigated whether the equilibrium theory of island biogeography (ETIB) can be applied to the meiofauna of groundwater-fed springs. We tested whether copepod species richness was related with spring area, discharge, and elevation. Additionally, five hypotheses are tested based on species distribution patterns, dispersal ability, and life-history characteristics of several guilds (stygobiot...

Evaluation of the Valuable Oxygenated Components in Iranian Rose Water

Rose water is one of the most important products obtained from Rosa genus (Rosaceae). Although Iran is one of the main producers of rose water, limited research has been done on it. A simple distillation and a Clevenger-type apparatus were used to obtain rose water and rose oil. All the volatile concentrates were investigated for their chemical composition by gas chromatography (GC) and gas chr...

Holy springs and holy water: underestimated sources of illness?

Use of holy springs and holy water is inherent in religious activities. Holy spring water is also used extensively for personal drinking water, although not assessed according to drinking water standards. Holy water in churches and chapels may cause infections via wetting of lips and sprinkling on persons. Our aim was to assess the microbiological and chemical water quality of holy springs and ...

Koopmans' springs to life.

The meaning of orbital energies (OOEs) in Kohn-Sham (KS) density functional theory (DFT) is subject to a longstanding controversy. In local, semilocal, and hybrid density functionals (DFs) a Koopmans' approach, where OOEs approximate negative ionization potentials (IPs), is unreliable. We discuss a methodology based on the Baer-Neuhauser-Livshits range-separated hybrid DFs for which Koopmans' a...
