(It would also be possible to add clauses to the formula to ensure that the three color classes are disjoint, but this makes no difference to the result.) Thus, by Courcelle's theorem, 3-colorability of graphs of bounded treewidth may be tested in linear time. For this variation of graph logic, Courcelle's theorem can ...

In one variation of the Gewald reaction a 3-acetyl-2-aminothiophene is synthesized starting from a dithiane (an adduct of sulfur and acetone if R = CH3 or acetaldehyde if R = H) and the sodium salt of cyanoacetone which in itself is very unstable: == References ==

In one variation the mechanism is thought to be as follows: The dichromate oxidizes the mercury, forming a layer of mercury oxide. In the process the dichromate is reduced to the chromium(III) ion. The oxidized layer on the mercury reduces the surface tension of the blob and the blob flattens out coming in contact with...

c_nxvlz48m93sy
Once there is no oxide coating left on the mercury blob, the surface tension increases and the blob rounds up and loses contact with the nail, ready to start the process over again. The net reaction is that the dichromate oxidizes the iron. This favorable reaction drives the mercury oxidations/reductions and the oscill...

In one variation, the game starts with no blocks on the field. Blocks fall down to the playing field, and must be removed before they reach the top.

In one-dimensional field theory or quantum mechanics one defines as "instanton" a field configuration which is a solution of the classical (Newton-like) equation of motion with Euclidean time and finite Euclidean action.

In one-host ticks the tick remains on the host through the larval, nymphal, and adult stages, only to leave the host to lay eggs.

Once a female is both fed and ready to lay eggs, only then does she leave the host in search of a suitable area to deposit her eggs. Ticks that follow this life cycle are called one-host ticks.

Females signal that they are ready to mate by shuddering the head, lowering the tail, and presenting their anogenital regions. Such solicitations do not always lead to copulation.

When langurs mate, they are sometimes disrupted by other group members. Females have even been recorded mounting other females.The gestation period of gray langur lasts around 200 days, at least at Jodhpur, India. In some areas, reproduction is year-around.

Year-round reproduction appears to occur in populations that capitalize on human-made foods. Other populations have seasonal reproduction.Infanticide is common among gray langurs. Most infanticidal langurs are males that have recently immigrated to a group and driven out the prior male.

These males only kill infants that are not their own. Infanticide is more commonly reported in one-male groups, perhaps because one male monopolizing matings drives the evolution of this trait. In multiple-male groups, the costs for infanticidal males are likely to be high as the other males may protect the infants and...

Nevertheless, infanticide does occur in these groups, and is suggested that such practices serve to return a female to estrous and gain the opportunity to mate.Females usually give birth to a single infant, although twins do occur. Most births occur during the night.
