When dry, the fruit are brown and resemble large brown peppercorns.

When serving a tour as drill sergeant this is indicated by the traditional campaign hat, commonly referred to as the " brown round " or " smokey bear ".

When pure and fine, travertine is white, but often it is brown to yellow due to impurities.

When first laid, the eggs are white or cream-colored and oval-shaped, but right before hatching they become kidney-shaped and brown.

When the mirror above the lens is moved too high or too low, it moves out of the best focal distance for an evenly white image, resulting in a projected image with either blue or brown color fringing around the outside edge of the screen.

When fired, the slip glaze varied from a chocolate to dark brown.

When bruised or cut, it either does not change colour, or turns a very light brown.

When cooked, it is nearly white, or a light golden brown.

When he showed this model as his `` solution '' as to how the Howe sewing machine operated, he was told he was `` wrong '', and discovered to his amazement that the Howe Machine, which was unknown to him in detail, used two threads while the one that he had perfected used only one.

When Governor Al Smith offered New York National Guard planes to fly the mail in and out of the state, it seemed a likely temporary solution, easing Burlington's bottleneck and that at Montpelier too.

When the solution finally came to him, one night while he was in bed, he was so shaken by its simplicity that he could only wonder why it had not occurred to him before.

When this happens, the carbon atoms are said to be in solution, or mixed with the iron, forming a single, homogeneous, crystalline phase called austenite.

When this happens the carbon atoms will no longer be soluble with the iron, and will be forced to precipitate out of solution, nucleating into the spaces between the crystals.

When rapidly cooled, a diffusionless ( martensite ) transformation occurs, in which the carbon atoms become trapped in solution.

When heated to form a solution and then cooled quickly, these alloys become much softer than normal, during the diffusionless transformation, and then harden as they age.

When the effects of compressibility on the solution are small, the aerodynamicist may choose to assume that density is constant.

When the pH of this solution rises, as a result of dilution by fresh water, these ions precipitate, forming " Yellow Boy " pollution.

When in solution, the calcium ion to the human taste varies remarkably, being reported as mildly salty, sour, " mineral like " or even " soothing.

When the partial pressure of is reduced, for example when a can of soda is opened, the equilibrium for each of the forms of carbonate ( carbonate, bicarbonate, carbon dioxide, and carbonic acid ) shifts until the concentration of in the solution is equal to the solubility of CO < sub > 2 </ sub > at that temperature and pressure.

When the condition number is exactly one, then the algorithm may find an approximation of the solution with an arbitrary precision.

When metal ions are reduced from ionic solution, they form a pure metal surface on the cathode.

When Newton's method is used to find the solution for the maximum likelihood estimate, the middle 24 % order statistics can be used as an initial solution for x < sub > 0 </ sub >.

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.

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
