Larva of a species in the family Sphingidae. The large eyespots on the back have no function concerning vision at all; when threatened, the caterpillar retracts its head, leaving the spots resembling either a threat, or as a more tempting target than the vulnerable head. The stemmata are visible as an arc of about four tiny spots slightly lateral to, and above the mouthparts. They are inconspicuous and do have a visual function.

La Senadora Martha Lucía Mícher Camarena durante la aprobación de las históricas reformas en materia de paridad (2019); estás reformas son producto de la lucha histórica de colectivos feministas y activistas de los derechos de las mujeres. La reforma que fue aprobada con una contundente mayoría de 120 votos, asegura el derecho de las mujeres a participar en todos los espacios políticos en condiciones de igualdad con los hombres.

"And when did you last see your father?" by William Frederick Yeames.The oil-on-canvas picture, painted in 1878, depicts a scene in an imaginary Royalist household during the English Civil War. The Parliamentarians have taken over the house and question the son about his Royalist father (the man lounging on a chair in the centre of the scene is identifiable as a Roundhead officer by his military attire and his orange sash[106]).

Heat flow vs. time for the thermal decomposition of 80 mass% CHP (cumene hydroperoxide) at a series of temperatures. CHP is an industrial chemical intermediate and polymerization initiator which is a documented fire and explosion hazard. According to the authors, neither differential scanning calorimetry or adiabatic calorimetry was sensitive enough to capture these data (from Chen et al. 2008 with publisher permission).
Fig. 4
Cumene hydroperoxide is common chemical intermediate compound which has been responsible for a number fires and explosions. IMC measurements at a series of temperatures provide data for creating a model of autocatalytic decomposition for use in establishing safe handling methods.
The most distinguishing features of the native pure bred horse are its lyre-shaped ears, which curve inward and often meet at the tips. Besides providing a sharp hearing, they can turn 180 degrees. Effectively blocking the ingress of the desert sand and dusty plains which are prevalent in this area. The coat is silky and often has the metallic shine of the Turkmeni horses. It comes in all colours, including piebald and skewbald

The Hubble eXtreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed. Except for the few stars in the foreground (which are bright and easily recognizable because only they have diffraction spikes), every speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 2 trillion galaxies.[1]
English: This image, called the Hubble eXtreme Deep Field (XDF), combines Hubble observations taken over the past decade of a small patch of sky in the constellation of Fornax. With a total of over two million seconds of exposure time, it is the deepest image of the Universe ever made, combining data from previous images including the Hubble Ultra Deep Field (taken in 2002 and 2003) and Hubble Ultra Deep Field Infrared (2009). The image covers an area less than a tenth of the width of the full Moon, making it just a 30 millionth of the whole sky. Yet even in this tiny fraction of the sky, the long exposure reveals about 5500 galaxies, some of them so distant that we see them when the Universe was less than 5% of its current age. The Hubble eXtreme Deep Field image contains several of the most distant objects ever identified.

Map of a proposed 2 ft (610 mm) gauge railroad that would have linked the WW&F with the Sandy River Railroad. The Franklin, Somerset and Kennebec Railway was chartered in 1897; construction began in 1901 on the northern portion of the line from Farmington to New Sharon.  The line was never completed because the Maine Central Railroad objected to a connection between the two narrow gauge lines on their property in Farmington.[1]

Terra de diatomeas vista con microscopía de campo brillante. A terra de diatomeas é un material sedimentario mol, silíceo feito das paredes celulares das diatomeas que se desfai formando un fino po. Estre exemplo consiste nunha mestura de diatomeas céntricas (simétricas radialmente) e pennadas (simétricas bilateralmente). Esta imaxe de partíclas de terra de diatomeas en auga abrangue un espazo de aproximadamente 1,13 × 0,69 mm.
English: Diatomaceous earth, also known as diatomite or kieselgur, as viewed under bright field illumination on a light microscope. Diatomaceous earth is a soft, siliceous, sedementary rock made up of the cell walls/shells of single cell diatoms and readily crumbles to a fine powder. Diatom cell walls are bivalve, i.e. made up of two halves, and are made up of biogenic silica; silica synthesised in the diatom cell by the polymerisation of silicic acid. This sample consists of a mixture of centric (radially symmetric) and pennate (bilaterally symmetric) diatoms. The primary uses of diatomaceous earth are for cleaning (scouring), filtration, heat-resistive insulation and as an inert absorbent substrate. One of the most famous uses was by Alfred Nobel who developed dynamite; a mixture of diatomaceous earth and nitroglycerin. This image of diatomaceous earth particles in water is at a scale of 6.236 pixels/μm, the entire image covers a region of approximately 1.13 by 0.69 mm.
