Computerized axial tomography in which the pixel sizes of the cross-sections of the 3-D object examined by radiography are in the micrometer range.

A form of spectroscopy in which photoelectrons excited by a beam of monochromatic x-rays are measured in order to find the characteristic binding energies of electrons at particular levels of the sample, thus identifying elements present there.

Technique applying x-ray diffraction to crystalline or powder samples in order to ascertain their structure.

Having the form or plan of two intersecting bars or lines of equal length, in which the intersection does not necessarily form right angles, and where the bars run diagonally across the vertical plane, that is, the base of the form rests on two arms that are not at right angles with the horizontal base plane. Resembling the letter "X." Use "cruciform" for forms or plans having two intersecting lines or bars at right angles, whether or not the bars are of equal length, and where the base of the form is perpendicular to the horizontal plane.

A very humble hut or dwelling generally constructed from poles with a thatched roof.

Colores anaranjados variables que se asemejan al color de la xantina, una secreción de diversos órganos animales.

Indigenous Mexican effigy braziers that functioned as receptacles for copal incense that, when burned, produced a thick, musky smoke that rose through openings in the figure.

Un compuesto débilmente básico (C5H4N4O2) aliado a ácido úrico, que se encuentra en varios órganos y secreciones del cuerpo de animales y de plantas, que forma un compuesto de color amarillo limón con ácido nítrico. Se deriva de guanina e hipoxantina, y produce ácido úrico en la oxidación.

Refers to an subclass (or "superorder" or "magnorder") containing the orders Cingulata and Pilosa, currently including 29 species among five living families. It includes the living anteaters, tree sloths, and armadillos, as well as the extinct ground sloths, glyptodonts and pampatheres. Xenarthrans were formerly grouped with pangolins and collectively referred to as edentates (a former order, Edentata), which alludes to the absence of teeth in some members.

Establecimiento que proporciona atenciones y alojamiento a los peregrinos y extrajeros, especialmente en contextos desde la época clásica a la medieval.

A heavy inert noble gas with symbol Xe or X and atomic number of 54, used principally in lamps, lasers, and as a general anaesthetic.

Proceso de fotocopiado en seco, no químico, en el que queda una imagen electrostática después de la exposición y es revelada mediante el depósito de un tóner.

General term for various species of dry-loving, extremophile molds that can cause illness to living creatures and damage to food, materials, structures, and objects. In art conservation, they are highly problematic because, unlike most molds, xerophilic molds thrive in low-humidity environments (\(<60\%\) RH) that are typically considered safe for collections. The molds cause active degradation of organic materials such as canvas, wood, paper, and leather. For example, Aspergillus halophilicus causes irreversible damage through staining, enzymatic degradation, and structural weakening, while often remaining undetectable by traditional methods.

Radiografía que utiliza una placa especialmente recubierta que permite que se revele un cuadro sin utilizar productos químicos líquidos.
