Energy diagram of a superconducting tunnel junction. The vertical axis is energy, and the horizontal axis shows the density of states. Cooper pairs exist at the Fermi energy, indicated by the dashed lines. A bias voltage V is applied across the junction, shifting the Fermi energies of the two superconductors relative to each other by an energy eV, where e is the electron charge. Quasiparticle states exist for energies greater than Δ from the Fermi energy, where Δ is the superconducting energy gap. Green and blue indicate empty and filled quasiparticle states, respectively, at zero temperature.
26 janvier, Sydney Cove : la fondation de l'Australie, toile d'Algernon Talmage, 1937. À l’arrivée du gouverneur Phillip, les aborigènes d'Australie sont de 300 000 à 400 000. Ils seront dix fois moins nombreux un siècle plus tard, refoulés vers les territoires du Nord et de l’Ouest. Les premiers contacts entre les colons et les aborigènes se passent mal. Les massacres commencent tôt, certaines coutumes indigènes (frapper les femmes au sang, broyer les cranes des soldats pris en embuscade) donnant bonne conscience aux Européens qui jugent « qu’il ne s’agit pas d’êtres humains mais de singes ».

The picture shown is of the Old High School in downtown Bisbee. It is the only four-story building in the country with a ground level entry on each floor. The entry shown is on the 2nd floor and was the main entry to the school. The first floor is under this and held the shop classes and the bus garage. The 2nd floor held the offices and general class rooms. The 3rd floor also was general classrooms while the 4th floor was the gym/auditorium. In the picture shown, there was a ground level entry halfway up for the 3rd floor, and at the top of the building was the ground level entry for the gym.
English: BISBEE HIGH SCHOOL. The TOWN IS SO HILLY THAT EACH FLOOR OF THE SCHOOL HAS A GROUND LEVEL ENTRANCE. Possibly in the Bisbee Historic District
1. Depois que uma célula T virgem (N) se encontra com o antígeno converte-se em célula T activada e começa a proliferar por mitose formando clones de células filhas.
2. Alguns dos clones de células T diferenciam-se em células T efectoras (E) que realizarão a função da célula (por exemplo, produzem citocinas no caso das células T colaboradoras ou uma actividade citotóxica no caso das células T citotóxicas).
3. Algumas destas células formam células T de cor (M) que sobrevivem em estado inactivo durante um comprido período de tempo até que se encontrem com o mesmo antíxeno de novo e se reactivem.
English: 1. After the naive T cell (N) encounters an antigen it becomes activated and begins to proliferate (divide) into many clones or daughter cells. 2. Some of the T cell clones will differentiate into effector T cells (E) that will perform the function of that cell (e.g. produce cytokines in the case of helper T cells or invoke cell killing in the case of cytotoxic T cells). 3. Some of the cells will form memory T cells (M) that will survive in an inactive state in the host for a long period of time until they re-encounter the same antigen and reactivate.
Hangar No. 2 (Building 29) at the former Marine Corps Air Station in Tustin, California measures 1,072 feet (327 m) long by 292 feet (89 m) wide by 192 feet (59 m) tall. It and its "sister" structure (partially visible to the right) are listed on the National Register of Historic Places and designated National Historic Civil Engineering Landmarks. The two hangars, built in 1942 of Oregon Douglas fir, are among the largest freestanding wooden structures in the world. 
While its sister structure (the North Hangar) is slated to be included in a new park, the future of this hangar is uncertain.[1]

English: Motion of gas molecules. The randomized thermal vibrations of fundamental particles such as atoms and molecules—gives a substance its “kinetic temperature.” Here, the size of helium atoms relative to their spacing is shown to scale under 1950 atmospheres of pressure. These room-temperature atoms have a certain, average speed (slowed down here two trillion fold). At any given instant however, a particular helium atom may be moving much faster than average while another may be nearly motionless. The rebound kinetics of elastic collisions are accurately modeled here. If the velocities over time are plotted on a histogram, a Maxwell-Boltzmann distribution curve will be generated. Five atoms are colored red to facilitate following their motions. Note that whereas the relative size, spacing, and scaled velocity of the atoms shown here accurately represent room-temperature helium atoms at a pressure of 1950 atmospheres, this is a two-dimensional scientific model; the atoms of gases in the real world aren’t constrained to moving in two dimensions in windows precisely one atom thick. If reality worked like this animation, there would be zero pressure on the two faces of the box bounding the Z-axis. The value of 1950 atmospheres is that which would be achieved if room-temperature helium atoms had the same inter-atomic separation in 3-D as they have in this 2-D animation.

Stochastic dynamical systems can be classified according to whether TS is spontaneously broken or not (ordered/symmetric) and whether the flow vector field is integrable or non-integrable (sometimes chaotic). Symmetric phase can be identified as thermal equilibrium (T). Ordered non-integrable phase can be called chaos (C) because it hosts conventional deterministic chaos. Ordered integrable phase can be called noise-induced chaos (N) because TS breaking involves anti-instantons that disappear in the deterministic limit. The N-phase is also known in the literature as self-organized criticality.

Exempel: Antag att skattenivån i utgångsläget är t' därefter höjer staten skatten till t*, vilket innebär ett förflyttning till höger längs kurvan från punkt B till punkt A. Vi har fått en högre skattenivå och staten ökade skatteintäkter. Antag vidare att staten höjer skatten igen till t''. Skattehöjningen innebär fortsatt förflyttning till höger längs kurvan från punkt A till punkt C. Vi har fått en högre skattenivå men staten får lägre skatteintäkter.

Il violista e compositore francese Marin Marais (1656-1728), ritratto da André Bouys nel 1704. Il travagliato rapporto di Marais con il suo maestro M. de Sainte Colombe (e con la figlia di questi) fu l'oggetto del romanzo Tutte le mattine del mondo di Pascal Quignard, da cui fu tratto l'omonimo film di Alain Corneau (1991). L'enorme successo del film, la cui colonna sonora includeva brani di Marais, di Sainte Colombe e di altri autori nell'esecuzione del violista e direttore catalano Jordi Savall, segnò in Francia un grande aumento dell'interesse per la musica antica presso il grande pubblico.

L'ambaixador francès César d'Estrées pugnà amb la Princesa dels Ursins per controlar al jove Felip V. Finalment acabà expulsat del Despacho i fou destituït com a ambaixador, essent rellevat pel seu nebot l'abat Jean d'Estrées; aquest pogué revenjar-se de la Ursins i veié com el 1704 era expulsada de la cort de Felip V per ordres del seu avi. Tot i així la Ursins féu valdre les seves influències amb el mariscal comte de Tessé i les dones dels monarques borbònics, Maria Lluïsa de Savoia i Madame de Maintenon respectivament, per a recuperar la seva posició i retornar a la cort de Felip V el 1705.
500. godine p. n. e. Rim je bio mali grad-država na apeninskom poluostrvu. Do 200. godine p. n. e. Rim je osvojio cijelu današnju Italiju, a tokom naredna dva vijeka osvojio je: Drevnu Grčku i Hispaniju (Španija, Portugal), sjevernoafričku obalu, veći dio Bliskog istoka, Galiju (Francuska i Belgija), i Britaniju (Engleska i Vels). Četrdeset godina rimskog osvajanje Britanije ostavilo je 250.000 mrtvih Britanaca, a car Antonin Pio sagradio je Antoninov zid preko Centralnog pojasa u Škotskoj kako bi odbranio provinciju od Kaledonaca. Ovaj bedem označavao je najsjeverniju granicu Rimskog carstva.

Oljemålningen Vidsträckt flodlandskap med vandrare vid en stenbro är ett av Carl Johan Fahlcrantz' tidigaste kända verk utfört i olja. "Enligt D. Widman, Carl Johan Fahlcrantz´ måleri, 1953, sidan 58 övergick Fahlcrantz från akvarell till olja kring sekelskiftet 1800. Detta år ställde han på Akademien ut sina två första kända oljemålningar. Stilistiskt kan målningen betraktas som en länk mellan det svenska landskapsmåleriet under 1700-talets sista del företrätt av bland andra Elias Martin, och 1800-talets landskapsmåleri präglat av en romantisk landskapssyn och intresse för naturens detaljer."

Shown are shape templates of amygdala, hippocampus, and ventricle generated from 754 ADNI samples` Top panel denotes the localized surface area group differences between normal aging and Alzheimer disease (positive represents atrophy in Alzheimer whereas negative suggests expansion). Bottom panel denotes the group differences in the annualized rates of change in the localized surface areas (positive represents faster atrophy rates (or slower expansion rates) in Alzheimer whereas negative suggests faster expansion rates (or slower atrophy rates) in Alzheimer); taken from Tang et al.[11][12][13]
English: Shown are subcortical structures in top row with ventricles shown bottom row. Superimposed in colors are the statistically significant changes.
Fig 1: These graphs depict the spectral distributions of an oversampled function and the same function sampled at 1/3 the original rate.  The bandwidth, B, in this example is just small enough that the slower sampling does not cause overlap (aliasing).  Sometimes, a sampled function is resampled at a lower rate by keeping only every Mth sample and discarding the others, commonly called "decimation".  Potential aliasing is prevented by lowpass-filtering the samples before decimation.  The maximum filter bandwidth is tabulated in the bandwidth units used by the common filter design applications.
