Phosphoryl Transfer Reaction Catalyzed by ITP3K. Hydrogen bonds are represented as dotted lines. Select ITP3K amino acids are shown in blue. Red arrows represent electron pushing. A metal cofactor (Mn2+, magenta) and a highly conserved Asp416 are essential for positioning the ATP beta- and gamma-phosphates. Arg319 (among other amino acids that are not shown) is involved in orienting IP3. Lys264 is most likely involved in neutralizing the negative charge that develops on phosphate, and it may also serve as a general base (hydrogen acceptor) for the 3'OH of IP3.
English: The nucleophilic attack of the gamma-phosphate of ATP by the 3'OH of inositol 1,4,5-trisphosphate is depicted. The mechanism for this phosphoryl transfer reaction was elucidated when the X-ray crystal structure of ITP3K was determined (Gonzalez et al., 2004). Hydrogen bonds are represented as dotted lines. Select ITP3K amino acids are shown in blue. Red arrows represent electron pushing. A metal cofactor (Mn2+, magenta) and a highly conserved Asp416 are essential for positioning the ATP beta- and gamma-phosphates. Arg319 (among other amino acids that are not shown) is involved in orienting IP3.

Panel del còmic web Xkcd titulat "Wikipedian protestor" o "Protestant de la Viquipèdia". En aquest s'observa un polític fent un discurs mentre un dels oients aixeca un cartell amb la frase "Cal citació" que s'utilitza en el context de la wikipedia quan un article fa una afirmació sense proveir una font. El còmic està publicat amb el text "SEMI-PROTECT THE CONSTITUTION", broma similar que barreja un concepte polític (Conservar la constitució dels Estats Units), amb un concepte de la wikipedia (semiprotegir una pàgina perquè no la pugui editar qualsevol usuari.)

Geometry of a GISAS experiment. The incident beam strikes the sample under a small angle close to the critical angle of total external x-ray reflection. The intense reflected beam as well as the intense scattering in the incident plane are attenuated by a rod-shaped beam stop. The diffuse scattering from the sample (red arrow) is recorded with an area detector. As an example the scattering from a block copolymer film with perpendicular lamellae is shown in the detector plane. The two lobes of scattering correspond to the lateral lamellar period of about 80 nm.

Panton, Leslie & Company reorganized in 1804 as John Forbes & Company, then sought to collect on its claims of debt against the Seminoles and the Lower Creeks. The Indians agreed to settle their debt by ceding land in 1806 and 1811 to the Spanish government, which conveyed the deeds for more than 1.2 million acres of land to its creditors, John Forbes & Company; this became known as the "Forbes Purchase". These grants comprised a tract of land on the Gulf of Mexico between the Apalachicola and Wakulla Rivers in Florida, extending inland twenty to thirty miles.

Ilustração esquemática das características essenciais de um sistema básico de pulverização catódica de diodos. O gás argônio flui através de uma válvula de vazamento controlada para uma câmara de deposição evacuada; alguns átomos de Ar são ionizados por um potencial DC aplicado entre o alvo de cobre e um substrato eletricamente condutor em uma mesa de substrato de metal. Íons de argônio são acelerados em direção ao alvo para ejetar os átomos de cobre, que são depositados no substrato, bem como nas paredes da câmara, para formar um filme de Cu. Adaptada de [1].

Centaurus A (NGC 5128 in the table below; Centaurus A is the radio source) is a nearby galaxy that contains a supermassive black hole actively powering a jet. A prominent X-ray jet extending for 13,000 light years points to the upper left in the image, with a shorter "counterjet" aimed in the opposite direction. In this image, low-energy X-rays are colored red, intermediate-energy X-rays are green, and the highest-energy X-rays detected by Chandra are blue. The dark green and blue bands running almost perpendicular to the jet are dust lanes that absorb X-rays.

Im Bauplan von Klövermarken eingezeichnetes Gesundheitssystem. Das Lager war in zehn Blöcke eingeteilt. Der Aufbau begann mit den Blöcken 1 und 2 mit Baracken für 16 Betten. Es folgten dann Baracken für 60-80 Betten. Die späteren Baracken im Nördlichen Bereich waren dann wieder kleiner. Zwischen den Blöcken mit Versorgungswegen waren die Latrinen angeordnet. Mittig an der Verbindungsstraße von West nach Ost, waren die Verwaltungsbaracken und die zentrale Küche. Rechts unten mit Hospital gekennzeichnet war ein Lazarett für deutsche Soldaten (Langzeitpatienten).

Four .30 caliber (7.62 mm) hollow point bullets.  Each of the three round-nose bullets on the left have a small cavity at the jacket opening on the leading tip of the bullet.  Such bullets are sometimes called open-point bullets in comparison to soft-point bullets where the lead core extends forward of the jacket.  The jacket of the very-low-drag bullet on the right provides an aerodynamic windscreen enclosing a hollow void so the center of mass of the lead core remains within the full diameter portion of the bullet to minimize misalignment with the bore axis.

Stilografia per la Vittoria del Palio di Asti da Parte della Madonna di Barbantana, località del Borgo San Lazzaro, prima nel suo genere e utilizzata coma intestazione per i sonetti fino all'inizio del XIX secolo. Sonetto per la vittoria del 1775. L'incisione raffigura l'antico percorso "alla lunga". Si vedono l'antica chiesa di San Lazzaro e il "cippo del pilone" (sullo sfondo), punto di partenza della corsa, San Secondo il patrono a cui la corsa è dedicata ed in primo piano due paggi a cavallo che stanno per entrare in città attraverso la porta di San Pietro

Le verrouillage gravitationnel conduit la Lune à avoir un mouvement de rotation sur son axe en autant de temps que ce qu'elle met pour parcourir une orbite autour de la Terre. En dehors des effets de libration, cela mène la Lune à avoir toujours la même face orientée vers la Terre, comme montré sur l'animation de gauche (Lune montrée en vue polaire, dessin pas à l'échelle). 
 Si la Lune ne tournait pas du tout sur elle-même, elle montrerait périodiquement sa face « avant » et sa face « arrière » lors d'une révolution, comme illustré sur l'animation de droite.
English: Tidal locking results in the Moon rotating about its axis in about the same time it takes to orbit the Earth. Except for libration effects, this results in it keeping the same face turned towards the Earth, as seen in the figure on the left. (The Moon is shown in polar view, and is not drawn to scale.) If the Moon didn't spin at all, then it would alternately show its near and far sides to the Earth while moving around our planet in orbit, as shown in the figure on the right.
Rent konkret är de psykologiska faktorerna information som hjärnan tar emot från yttervärlden. Inne i hjärnan sker informationsförmedlingen från nervcell till nervcell med hjälp av signalsubstanser. Dessa aktiverar receptorer som påverkar nervcellens elektriska laddning genom jonkanaler för  Na+, K+, Ca++ eller Cl-. Ju högre spänningsskillnad desto lättare skickas en nervimpuls. Receptorerna kan också aktivera G-proteiner som påverkar vilka gener cellen använder. Generna kan exempelvis koda för jonkanaler, receptorer, eller styra syntesen av signalsubstanser.
