BOD test bottles at the laboratory of a wastewater treatment plant. Biochemical oxygen demand (also known as BOD or biological oxygen demand) is an analytical parameter representing the amount of dissolved oxygen (DO) consumed by aerobic bacteria growing on the organic material present in a water sample at a specific temperature over a specific time period.

A dowser, from an 18th-century French book about superstitions. Dowsing is a type of divination employed in attempts to locate ground water, buried metals or ores, gemstones, oil, claimed radiations (radiesthesia), [1] gravesites, [2] malign "earth vibrations" [3] and many other objects and materials without the use of a scientific apparatus.
The BOD 5 standard is also an indicator of the presence of settleable solids in water, but specifically for organic matter. BOD 5 represents the amount of oxygen required by microorganisms to stabilize organic material present in wastewater. A higher concentration of BOD 5 means a high load of organic matter to be stabilized by microorganisms.
Kiwa puravida is a species of deep-sea dwelling decapod, a member of the genus Kiwa, a genus of animals sometimes informally known as "yeti crabs". [1]The crabs live at deep-sea cold seeps where they feed on symbiotic Pseudomonadota, which they cultivate on hair-like projections on their claws.
The feedback gain at low frequencies and for large A OL is A FB ≈ 1 / β (look at the formula for the feedback gain at the beginning of this section for the case of large gain A OL), so an equivalent way to find f 0 dB is to look where the feedback gain intersects the open-loop gain. (Frequency f 0 dB is needed later to find the phase margin.)
This is a list of film directorial debuts in chronological order. The films and dates referred to are a director's first commercial cinematic release.Many filmmakers have directed works which were not commercially released, for example early works by Orson Welles such as his filming of his stage production of Twelfth Night in 1933 or his experimental short film The Hearts of Age in 1934.
Multiple organ dysfunction syndrome (MODS) is altered organ function in an acutely ill patient requiring immediate medical intervention. [ 1 ] There are different stages of organ dysfunction for certain different organs, both in acute and in chronic onset, whether or not there are one or more organs affected.
