Metal laboratory sieves An ami shakushi, a Japanese ladle or scoop that may be used to remove small drops of batter during the frying of tempura ancient sieve. A sieve, fine mesh strainer, or sift, is a tool used for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet ...
Sieve tube members are shorter and wider with greater area for nutrient transport while sieve cells tend to be longer and narrower with smaller area for nutrient transport. Although the function of both of these kinds of sieve elements is the same, sieve cells are found in gymnosperms, non-flowering vascular plants, while sieve tube members are ...
Sieve (hieroglyph), an ancient Egyptian hieroglyph; Sieve, or strainer, on rivers is a dangerous obstacle that water can pass through, but people cannot (see Obstacle in whitewater canoeing) Sieve, in sports such as hockey or lacrosse, is a common slang term used when referring to a goaltender who allows many or weak goals
A molecular sieve is a material with pores (voids or holes), having uniform size comparable to that of individual molecules, linking the interior of the solid to its exterior. These materials embody the molecular sieve effect , the preferential sieving of molecules larger than the pores.
In number theory, the larger sieve is a sieve invented by Patrick X. Gallagher.The name denotes a heightening of the large sieve.Combinatorial sieves like the Selberg sieve are strongest, when only a few residue classes are removed, while the term large sieve means that this sieve can take advantage of the removal of a large number of up to half of all residue classes.
These sieves are called covering sieves. The set of all covering sieves on an object c is a subset J(c) of Sieve(c). J(c) satisfies several properties in addition to those required by the definition: If S and S′ are sieves on c, S ⊆ S′, and S ∈ J(c), then S′ ∈ J(c). Finite intersections of elements of J(c) are in J(c).
Cribrarula cribraria, the 'sieve/tan and white cowry', is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries. [ 1 ] Description
The large sieve is a method (or family of methods and related ideas) in analytic number theory.It is a type of sieve where up to half of all residue classes of numbers are removed, as opposed to small sieves such as the Selberg sieve wherein only a few residue classes are removed.
