OPTIMIZATION OF GROUND WATER CUTOFF WITH A SIPHON INTAKE FROM THE DRAIN WELLS (AS IN THE CASE OF KAMYANKA-DNIPROVSKA GROUND WATER CUT-OFF)

open access: yesМеліорація і водне господарство, 2019
Relevance of research.To increase the efficiency and reliability of the territory protection against flooding with the infiltration water of the Kakhovsky Reservoir, it is proposed to replace the low-performance ground water cutoff with an airlift water ...

Rotenone Induces Morphological Damage and Reduction in Catecholamine Levels in the Central Nervous System of the Ascidian Styela plicata

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Ascidians are invertebrates that occupy a key phylogenetic position as a sister group of the vertebrates. The organization of their central nervous system (CNS), with cortex and medulla, indicates a plesiomorphic character of the gray and white matter of vertebrates, making this group of animals useful for studies of neurodegenerative events ...

Flow Field Simulation Analysis of Train Siphon Toilet with Variable Pipe Diameter Based on the Investigation of Siphon Performance

open access: yes, 2020
The performance of siphon toilets in trains with varied pipe profiles were investigated. The profiles of the siphon pipe are varied based on the diameter of the pipe along the pipe length. The flushing process was simulated by using CFD method.

Wildfire Ash Alters Freshwater Crustacean Behavior: Disentangling the Contributions of Suspended Macroparticles and Ash‐Induced Alkalinization

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...

How weather got its words: a history of meteorological English – Part 2: the scientific age and beyond

open access: yesWeather, EarlyView.
The English language is a gargantuan, gluttonous beast. It has become extraordinary in its powers of assimilation – such that we rarely consider the origins of the words we use. In this paper, we will shed light on these origins, including the Pontic–Caspian steppe, the British Empire and, of course, a TV show.

Life history attributes influencing metabolic variation in an estuarine fish

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Considering that energy availability and oxygen transport potential are limited in supplying metabolic requirements, all animals face trade‐offs between competing metabolic demands.

Demo 13-10 Siphon

open access: yes, 2001
A siphon uses a tube to transfer a liquid from one container into a lower one, as shown in Figure 1. Atmospheric air pressure keeps the liquid in the transfer hose, making the water column "unbreakable." The weight of the liquid on the vertically ...

Transcriptional breakpoints as predictors of thermal thresholds in a climate‐impacted stenothermal fish

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The biogeography of ectotherms is greatly influenced by their thermal tolerance, which is expected to be tightly coupled to aerobic performance. However, preferred temperatures of ectotherms often deviate substantially from aerobic performance optima. This suggests that

Time lapse photography with two different camera systems for in situ observation of the bivalve Diplodon chilensis (Gray, 1828) in a southern Chilean lake

open access: yesGayana, 2019
During the last 40 years time lapse photography has become a strong tool for in situ observations of marine and freshwater wildlife. We compared the validity of two low cost camera systems to analyze the filtration activity of Diplodon chilensis (Gray ...
