IV ECONOMY Cincinnati, from its earliest beginnings, has functioned as a major port on the Ohio River. Distribution of raw materials as well as manufactured goods is one of the city’schief economic activities. Although Cincinnati remains one of the world’s leading centers for the distribution of bituminous (soft) coal, this trade is gradually declining. Coal from Kentucky and W...

Leaf - biology.
The mesophyll, sandwiched between the upper and lower epidermis, consists of many thin-walled cells that are usually arranged in two layers. The palisade layer is next to the upper epidermis. It consists of cylindrical cells that are packed closely together. Next to the palisade layer and making up most of the thickness of the leaf bladeis the spongy layer. The spongy layer consists of roundish cells that are packed loosely together and have numerous air spaces between them. In most plants t...

Light
I
INTRODUCTION
Light, form of energy visible to the human eye that is radiated by moving charged particles.
simulates the action of a moving charge upon the electric field. It creates a wave that travels along the rope in a direction that is perpendicular to the initial up anddown movement. Because electromagnetic waves are transverse—that is, the vibration that creates them is perpendicular to the direction in which they travel, they are similar to waveson a rope or waves traveling on the surface of water. Unlike these waves, however, which require a rope or water, light does not need a medium, or su...

oxydoréduction - chimie.
Si l’on est à 25 °C, soit 298 K, la formule de Nernst devient : E0 est le potentiel normal, ou standard, du « couple rédox » ; il caractérise le pouvoir oxydant de la forme oxydée, ou le pouvoir réducteur de la forme réduite, et ne dépend que de la température. Ainsi, on ordonne les couples rédox selon la valeur de leur potentiel normal d’oxydoréduction : plus ce potentiel est élevé, plus le pouvoir oxydant de la forme oxydée est important. 6 PRÉVISION DES RÉACTIONS En solution, lorsque l’on a...

Estas cadenas están presentes en todos los vertebrados, en los que representan una parteespecial del siste...

Maris Breaks Home Run Record.
Bothered by an injured hip, Mantle was removed from the lineup in mid-September with 54 long balls, leaving Maris alone in the home-run derby.

Rembrandt.
myth that the painting was rejected by those who commissioned it, and led to a decline in Rembrandt's reputation and fortune, it was actually well received. Many of Rembrandt's landscapes in this middle period are romantic and based on his imagination rather than recording specific places. The inclusion of ancient ruins androlling hills, not a part of the flat Dutch countryside, as in River Valley with Ruins (Staatliche Gemäldegalerie, Kassel), suggests a classical influence derived from Italy...

Gemstones.
In the late 1960s a method was developed for “growing” diamonds by heating a diamond particle to a high temperature and subjecting it to methane gas. The gasdecomposes into carbon atoms, which adhere to the diamond crystal. The crystal structure of the enlarged diamond is identical to that of a natural diamond. Diamondsof about 1 carat (200 mg or 0.007 oz) have been produced by this method, but their cost is still considerably higher than that of naturally occurring diamonds. Sapphires are made...

Coral Reef.
sensitive to particles of mud or sediment settling on them, which means that corals rarely grow close to rivers or other sources of sediment. In the sea, light is filteredout by depth, so reef-building corals can only grow in relatively shallow water. Even in the clearest oceans few reef-building corals grow below a depth of 80 to 100 m(260 to 328 ft). Although corals need nutrients, they cannot thrive in areas where there are large amounts of nutrients. Typically, microscopic organisms in the p...

The formula H 2 describes a hydrogen molecule, a discrete unit. When a molecule contains just two atoms, such as the hydrogen molecule does, it is called a diatomic molecule. Some atoms can form covalent bonds with more than one other atom and thus create a larger molecule. Atoms form molecules with covalent bo...

Indian Treaties in Canada - Canadian History.
