Surfactin is a cyclic lipopeptide, commonly used as an antibiotic for its capacity as a surfactant. [2] It is an amphiphile capable of withstanding hydrophilic and hydrophobic environments. The Gram-positive bacterial species Bacillus subtilis produces surfactin for its antibiotic effects against competitors. [ 3 ]
21st-century hunting compound crossbow. A crossbow is a ranged weapon using an elastic launching device consisting of a bow-like assembly called a prod, mounted horizontally on a main frame called a tiller, which is hand-held in a similar fashion to the stock of a long gun. Crossbows shoot arrow-like projectiles called bolts or quarrels.
A small multiple (sometimes called trellis chart, lattice chart, grid chart, or panel chart) is a series of similar graphs or charts using the same scale and axes, allowing them to be easily compared. It uses multiple views to show different partitions of a dataset.
Surfactants with a low critical micelle concentration (CMC) are favored; the polymerization rate shows a dramatic increase when the surfactant level is above the CMC, and minimization of the surfactant is preferred for economic reasons and the (usually) adverse effect of surfactant on the physical properties of the resulting polymer. Mixtures ...
Inside of an arrowslit, where an archer would stand, at Corfe Castle. Exterior view of arrowslits in the Bargate gatehouse in Southampton. An arrowslit (often also referred to as an arrow loop, loophole or loop hole, and sometimes a balistraria [1]) is a narrow vertical aperture in a fortification through which an archer can launch arrows or a crossbowman can launch bolts.

[ 1 ] The word quarrel is from the Old French quarrel (> French carreau ) "square thing", [ 2 ] specialized use as quarrel d'arcbaleste (> carreau d'arbalète ...
Match crossbow is a target shooting sport using crossbows. Unlike field crossbow, match crossbow is quite similar to the Olympic rifle. The International Crossbow Shooting Union (Internationale Armbrustschutzen Union-IAU) is the world governing body of crossbow target shooting. Founded 24.
Triton X-100 (C 14 H 22 O(C 2 H 4 O) n) is a nonionic surfactant that has a hydrophilic polyethylene oxide chain (on average it has 9.5 ethylene oxide units) and an aromatic hydrocarbon lipophilic or hydrophobic group. The hydrocarbon group is a 4-(1,1,3,3-tetramethylbutyl)-phenyl group.
