Aerial view of the La Plata crossing into New Mexico from Colorado, with La Plata, New Mexico, in left foreground.  Mesa Verde is in the right background. Further, at about 40 miles, just left of center, is Colorado's Ute Mountain.  Between the mesa and the sleeping Ute is Navajo Wash, extending to the left toward its confluence with the Mancos River.  Even further, at about 100 miles, the Abajo Mountains, in Utah, are visible on the horizon.

The combined WKAL studio and transmitter facility, South Jay Street, Rome, NY; Spring 1974. FM Stereo service had been recently initiated, simulcasting AM programming. The station's building markings were updated to advertise the change. To the left the station's VW Bus can be seen which was utilized during this period for promotional events. As of 2018[update], only the concrete pad remains to mark the location where the building once stood.

Sacerdote nacido en Valladolid hacia 1765, José María Morelos fue arriero y alumno de Hidalgo. Cura de Carácuaro al estallar la guerra, se unió a los insurgentes y fue convirtiéndose en el artífice militar de la causa. Su mayor triunfo fue el Sitio de Cuautla, donde venció a Calleja. En pleno declive, convocó al Congreso de Chilpancingo y promulgó la Constitución de Apatzingán. Capturado, fue enjuiciado y ejecutado el 22 de diciembre de 1815.

Georgi Parvanov is the third democratically elected president. While he personally does not hide his sympathies towards Russia and is regularly speaking for the need of development of Bulgarian and Russian energy projects, he also gave a serious support for the government of Simeon Saxe-Coburg-Gotha in its effort of joining in NATO and also made possible the three-coalition of Sergei Stanishev which accomplished the joining of Bulgaria to EU.

Una estructura de banda electrónica de un semiconductor (derecha) incluye la relación de dispersión de cada banda, es decir, la energía de un electrón E como una función del vector de onda del electrón k. La "banda sin relleno" es la banda de conducción del semiconductor; está curvada hacia arriba indicando masa efectivapositiva. La "banda llena" es la banda de valencia del semiconductor; se curva hacia abajo indicando masa efectiva negativa.

Het energieverbruik per afstand ligt bij de mens bij het rennen bijna tweemaal zo hoog als bij een paard. Elke gang van een paard kent een optimale snelheid waarbij het energieverbruik per afstand minimaal is. Het dikkere deel van de lijn is de voorkeurssnelheid bij die gang. Daaronder en daarboven neemt het energieverbruik toe. Een uitzondering is het rennen bij de mens, waarbij het energieverbruik per afstand afneemt bij toenemende snelheid

Tetradrachm of the Parthian king Vologases I, struck at Seleucia. On the reverse is a portrait of the king wearing a trouser-suit, diadem and beard. The observe depicts an investiture scene, where the king is receiving a scepter by the Greek goddess Tyche. In the Parthian era, Iranians used Hellenistic iconography to portray their divine figures,[1] thus the investiture scene can be associated with the Avestan khvarenah, i.e. kingly glory.[2]

Vue schématique de paires électron-positron virtuelles apparaissant au hasard près d'un électron (en bas à gauche). Les particules virtuelles, portant une charge électrique, masquent en partie la charge de l'électron pour les autres particules. Puisqu'il y a un nombre immense de particules virtuelles qui existent à tout moment, la charge électrique de l'électron nu — si une telle entité existe — est donc infinie selon l'équation de Dirac[67].
English: This is a graphical representation of virtual electron-positron pairs randomly popping into existence near a (non-virtual) electron (lower left). The coulomb force from the (non-virtual) electron briefly separates the pairs before they snap back together and vanish. This separation partially shields the (non-virtual) electron's charge from the outside.

Jelikož nikdo z posádky nepřežil, jsou hlášení a fotografie pořízené americkými letci jedinými zdroji k objasnění konce tohoto torpédoborce. Na fotografiích je Asašimo jasně identifikovatelný podle dvou dělových věží na zádi a jedné na přídi (ostatní torpédoborce předchozích tříd, účastnící se operace Ten-gó, měly dělovou věž č. 2 na zádi odstraněnou ve prospěch dalších 25mm kanónů).

Below left is a refinement of a cover (above) of a planar shape (dark) so that all points in the shape are contained in at most three sets. Below right is an attempt to refine the cover so that no point would be contained in more than two sets. This fails in the intersection of set borders. Thus, a planar shape isn't "webby" or cannot be covered with "chains", but is in a sense thicker; i.e., its topological dimension must be higher than one.
