La contrada della Scala nel 1855, prima della realizzazione dell'omonima piazza. I portici che si intravedono sulla destra appartengono al Teatro alla Scala. Per realizzare piazza della Scala vennero demoliti, nel 1858, diversi caseggiati, che si intravedono nella fotografia. In questo modo scomparve la via prospiciente al celebre teatro milanese, la contrada della Scala (in molte città lombarde, fino all'Unità d'Italia, le vie erano comunemente chiamate "contrade")

An Egyptian fellah woman, a peasant or farmer, distinguished from the effendi land-owning class, painted by Elisabeth Jerichau-Baumann in 1878. Jerichau-Baumann based this and similar works on her experiences travelling the Ottoman Empire in 1869–1870 and 1874–1875. Unlike many of her contemporaries, she had access to the region's harems and could base her paintings on personal observation. Many of her subjects insisted on being painted in the latest Paris fashions.
Virgen de Belén, escuela de Cuzco, ca. 1700-1720. Las imágenes de la Virgen en América tuvieron una gran importancia en la cristianización. La condición de la más famosa de ellas, Nuestra Señora de Guadalupe (México), es todavía objeto de debate: su milagrosa aparición en el ayate de Juan Diego Cuauhtlatoatzin (por lo que sería "de manos no humanas", como los antiguos iconos acheiropoietos) o su pintura por Marcos Cipac de Aquino, ambos indígenas de la época (1531).

Al iniciar el mes de enero de 1907, los obreros de Río Blanco, Veracruz, formaron una cooperativa sindical para defender sus derechos ante los patronos. El 7 de enero suspendieron su trabajo en protesta por las medidas de los dueños, y entonces comenzó la Huelga de Río Blanco, que fue reprimida rápida y violentamente por los miembros del Ejército Mexicano. Años más tarde, este incidente fue recordado contra Díaz en los primeros movimientos de la Revolución mexicana.

This image illustrates the three separate steps of hydrolysis involved in lipolysis. In the first step, triacylglycerol is hydrolyzed to make diacylglycerol and this is catalyzed by adipose triglyceride lipase (ATGL). In the second step, diacylglycerol is hydrolyzed to make monoacylglycerol and this is catalyzed by hormone-sensitive lipase (HSL). In the last step, monoacylglycerol is hydrolyzed to make glycerol and this is catalyzed by monoacylglycerol lipase (MGL).

Tijekom 13. i 14. stoljeća, slavonski su banovi kovali svoje novce, banski dinar ili banovac. Na licu dinara nalazila se kuna u trku između križa i zvijezde Danice. Kralj Vladislav II. Jagelović podijelio je grb Kraljevini Slavoniji, grbovnicom iz 1496. Hrvatski su staleži 1497. napravili pečat sa spomenutim grbom, koji je do kraja 18. stoljeća bio službeni pečat čitave Trojedne Kraljevine, kako to dokazuju zapisnici svih hrvatskih sabora od sredine 16. stoljeća.[1]

Schema di una "growth fault" (o faglia di crescita). Il lato ribassato della faglia è a destra. In corrispondenza del lato ribassato, il maggiore accumulo di sedimenti (e quindi il maggiore peso) determina una maggiore deformazione degli strati (uncinatura o, nella terminologia anglosassone, drag) che si accentua fino a formare una vera e propria piega anticlinale (anticlinale di rollover), che può costituire una trappola per gli idrocarburi (oil trap nella figura).

Efecto del factor anómalo de forma: El vector FH es la contribución al factor de estructura de un átomo pesado a una longitud de onda con dispersión anómala baja. El vector FHA es el factor de estructura para la misma reflexión cerca de un salto de absorción donde las magnitud del efecto anómalo es mayor. La componente imaginaria del factor anómalo causa un cambio de fase, y ambas componentes alteran la amplitud (igual al módulo del vector) del factor de estructura.

Separating the African (or Nubian-Somali plates) and Antarctic plates, the Southwest Indian Ridge (SWIR) stretches 7,700 km (4,800 mi) from the Atlantic Ocean to the Indian Ocean. With an average spreading rate of 14–15 millimetres per year (0.55–0.59 in/year), the SWIR is one of the slowest-spreading mid-ocean ridges on Earth.  Characterised by numerous large transform offsets, most of the SWIR is highly segmented and oblique relative to the spreading direction.[1]

Cartoon representando Columbia (personificação feminina dos EUA) diante de um muro separando dois grupos. À esquerda é Boss Tweed tentando alcançar dentro de um saco com três companheiros ao lado dele. Um arco atrás de Boss é rotulado de "escola de ladrões". À direita estão os republicanos liberais: Thomas W. Tipton, Carl Schurz, Lyman Trumbull, Horace Greeley, Reuben Fenton e um outro. Atrás dos liberais republicanos está um arco rotulado de "escola de escândalos".
English: Columbia (female personification of the USA) stands before a wall separating two groups. On the left is Boss Tweed reaching into a bag with three companions standing beside him: an arch behind is labeled "SCHOOL FOR THIEVES". On the right are the Liberal Republicans: Thomas W. Tipton, Carl Schurz, Lyman Trumbull, Horace Greeley, Reuben Fenton and one other: an arch behind is labeled "SCHOOL FOR SCANDAL". Both factions are identified with the McClellan-Vallandigham campaign of 1864: "1864 - Anything to beat A. Lincoln; 1872 - Anything to beat U.S. Grant".

Знаме ушито от учителката Мария Капитанчева през зимата на 1903 г. по указание на Апостол Петков. На 20 юли 1903 г. в село Корнишор, пред него се заклеват 250 четници от Енидже-Вардарскте чети на Апостол Петков, Иванчо Карасулията и Кръстьо Асенов. След въстанието знамето е спасено от отец Димитър Джутев от българската църква „Св. св. Кирил и Методий“ в града.

"Cuando Walt Disney dirigía la compañía, hubiera sido impensable que una ex estrella de Disney siguiera esta ruta. No me puedo imaginar a ningún padre, sabiendo qué tipo de persona es Miley en su etapa actual, dejando que sus hijos se apeguen demasiado al personaje de Hannah Montana. Por eso, Disney puede verse obligado a retirar al personaje del todo". Melissa Henson del Parents Televisión Council discute la conexión entre la serie y la carrera continuada de Cyrus.

Beam is a crossing-point of several lines of communication. Map of environs of Beam House. Henry Williamson made several references to Beam in his 1927 novel Tarka the Otter including the following descriptive passage: "A quarter of a mile below Rothern Bridge the river slows into the lower loop of a great S. It deepens until half-way, where the S is cut by the weir holding back the waters of the long Beam Pool. Canal Bridge crosses the river at the top of the S"[2]

Illustration du mécanisme de base de la fusion en fusors. (1) Le fusor contient deux cages métalliques concentriques. La cathode est à l'intérieur de l'anode. (2) les ions Positifs sont attirés à l'intérieur vers la cathode. Ils sont accélérés dans la chute de tension. Le champ électrique assure le chauffage des ions du plasma jusqu'aux conditions de fusion. (3) Les ions manquent la cage interne. (4) Les ions entrent en collision aux centre et peuvent fusionner[21].
English: This is an illustration of the fusion mechanisms in a fusor; also known as a Hirsch-farnsworth fusor or a Spherically Convergent Ion Focus (SCIF). This description is taken from the dissertation: "Ion Flow and fusion reactivity characterization of a spherically convergent ion focus" by Tim Thorson, Wisconsin-Madison, 1996. (1) The fusor contains two wire cages - also known as grids - one inside the other. The inner cage is the cathode, while the outer cage is the anode. Ions are introduced, injected or generated inside the two cages. (2) The ions accelerate down the voltage drop towards the inner cage. The electric field is doing physical work on the ions, heating them, to fusion conditions. (3) The ions must miss the inner cage. (4) If they collide, or are concentrated in the center grid, they can fuse. This is the basic mechanism for nuclear fusion in fusors.
