When used in the extemporaneous preparation of topical medications, it is supplied in the form of Coal Tar Topical Solution USP, which consists of a 20 % w / v solution of coal tar in alcohol, with an additional 5 % w / v of polysorbate 80 ; this must then be diluted in an ointment base such as petrolatum.

Though attractive in many cases, a general-purpose DBMS is not always the optimal solution: When certain applications are pervasive with many operating instances, each with many users, a general-purpose DBMS may introduce unnecessary overhead and too large " footprint " ( too large amount of unnecessary, unutilized software code ).

When faced with a new circuit, the software first tries to find a steady state solution, that is, one where all nodes conform to Kirchhoff's Current Law and the voltages across and through each element of the circuit conform to the voltage / current equations governing that element.

When present together in solid solution, energy is transferred from the higher-energy tungsten to the lower-energy molybdenum, such that fairly low levels of molybdenum are sufficient to cause a yellow emission for scheelite, instead of blue.

When the brown solution of iodine in strong donor solvents were heated, a color transition from brown to violet is observed as the weakly-bonded charge-transfer complex dissociates into to free solvent and iodine molecules.

When Charles tried to find a compromise solution with the Augsburg Interim, Bucer and Bullinger urged Calvin to respond.

Ribbentrop quickly learned that Hitler always favoured the most radical solution to any problem, and accordingly tended his advice in that direction as a Ribbentrop aide recalled: When Hitler said ' Grey ', Ribbentrop said ' Black, black, black '.

When dissolving a lipophilic or amphiphilic substance in a polar environment, the polar molecules ( i. e., water in an aqueous solution ) become more ordered around the dissolved lipophilic substance, since the polar molecules cannot form hydrogen bonds to the lipophilic areas of the amphiphile.

When this is the case, and x < sub > 0 </ sub > is one solution of ( 1 ), then the set of all solutions is given by

When the solution comes into contact with air the chemical reaction that created it is reversed and particles of calcium carbonate are deposited.

When the husband drops the case and returns to his wife, both seem sorry they brought the matter up in the first place.

When you drive a car at night through falling rain, the rain drops illuminated by your car's headlights appear to fall from a position in the sky well in front of your car.

When the temperature drops below 50 ° F ( 10 ° C ), feeding, particularly with protein, is halted or the food can spoil in their stomachs, causing sickness.

When you see him, recognise him: a man of medium height, reddish hair, wearing two light yellow garments, looking as if drops were falling down from his head though it will not be wet.

When an SI prefix is affixed to a root word, the prefix carries the stress, while the root drops its stress but retains a full vowel in the syllable that is stressed when the root word stands alone.

When it exceeds the design temperature it opens the contacts, cooling until the temperature drops enough to restore magnetisation.

When a certain preset coin capacity is reached, a coin diverter automatically redirects, or " drops ," excess coins into a " drop bucket " or " drop box.

When a Frame Relay network detects an error in a frame, it simply drops that frame.

When Frame Relay detects an error, it simply drops the offending packet.

When the non-inverting input ( V +) drops below the inverting input ( V -), the output saturates at the most negative voltage it can output.

When power loss occurs, the rectifier simply drops out of the circuit and the batteries keep the power steady and unchanged.

When she accidentally bumps into him a second time and realizes she is smitten, she is fortunate to be on the scene to pick up his photo album when he drops it in the street.

When the water drops below a certain level, a pressure switch, level switch or float valve will activate a pump or open a public water line to refill the water tower.

When more common dielectrics are considered, the best-loss impedance drops down to a value between 52 – 64 Ω.

When the condemned drops to the end of the rope, the force is supposed to break the neck.

When surface temperature drops, eventually reaching the dew point, atmospheric water vapor condenses to form small droplets on the surface.

* Priority activation: When the number of available servers drops below a certain number, or load gets too high, standby servers can be brought online

When the pH drops, luciferase changes its shape, allowing luciferin, more specifically tetrapyrrole, to bind.

When Nelson almost drops out of school to spend more time on the company, Lisa is saddened and attempts to stop him from doing so, but eventually respects his decision after realising he won't change despite the money used to fund it.

When current flows, however, the voltage across the terminals of the source of emf is no longer the open-circuit value, due to voltage drops inside the device due to its internal resistance.

When this does not shut him up, the audience member drops an anvil on Poochini's head, squashing him down and giving him a deeper voice reminiscent of the Ink Spots ' spoken interludes, or of Eddie ' Rochester ' Anderson.
