Viola glabella prefers moist, well-drained soil and can grow in part shade. Acidic and neutral soils are suitable for Viola glabella, which prefers a pH between 6 and 6.5, and becomes chlorotic if the pH is too high. [1] Young leaves and flower buds are edible, raw or cooked, but the yellow flowers can cause diarrhoea. [2]
There is a rapid cold hardening capacity found within certain insects that suggests not all insects can survive a long period of overwintering. Non-diapausing insects can sustain brief temperature shocks but often have a limit to what they can handle before the body can no longer produce enough cryoprotective components. The common fruit fly
H1a, higher than 15 °C (59 °F), applies to tropical plants permanently under glass in heat; while H7, below −20 °C (−4 °F), applies to very cold-tolerant plants such as heathers. Most outdoor plants in the UK fall within the range H4, −10 to −5 °C (14 to 23 °F) (hardy in the average winter) to H5, −15 to −10 °C (5 to 14 °F ...
In laboratory experiments, bioretention cells removed 94%, 88%, 95%, and >95% of zinc, copper, lead, and cadmium, respectively from water with metal concentrations typical of stormwater runoff. While this is a great benefit for water quality improvement, bioretention systems have a finite capacity for heavy metal removal.
Raw water is generally unsafe for human consumption due to the presence of contaminants. A major health problem in some developing countries is use of raw water for drinking and cooking. [1] Without treatment, raw water can be used for irrigation, construction, or cleaning purposes. [2]
Viola praemorsa is a species of violet known by the common names canary violet, [3] Astoria violet, [4] yellow montane violet, and upland yellow violet. [5] Description
An example of a water distribution system: a pumping station, a water tower, water mains, fire hydrants, and service lines [1] [2]. A water distribution system is a part of water supply network with components that carry potable water from a centralized treatment plant or wells to consumers to satisfy residential, commercial, industrial and fire fighting requirements.
Viola labradorica, commonly known as alpine violet, [2] American dog violet, [3] dog violet [4] or Labrador violet, [3] [5] [6] is a perennial herbaceous flowering plant. It is native to Greenland, eastern Canada, and the eastern United States. [7] The plant sold as Viola labradorica by nurseries is Viola riviniana. [8]
