The expository texts They offer the reader detailed information on a specific topic of reality, with the aim of transmitting knowledge, facts, data or concepts in an objective way, that is, without involving the author’s opinions. For example: an encyclopedic entry.
These types of texts are present in all scientific and academic fields, from the most formal sciences to the humanities. In them, denotative language and formal language are usually prioritized. For example: a school manual or an exam.

Everything that occupies space is called matter. A body is a portion of matter that has definite limits. It starts in one place and ends in another. In conclusion, all bodies, being made up of matter, occupy space, and that space cannot be occupied by other bodies at the same time.
Bodies can be in a liquid, solid or gaseous state. These presentations are called aggregation states. A table, for example, is a solid body made up of matter of different origins, and each one is called a material, for example: metals, plastics and wood.

the solar system
The solar system is the planetary system that gravitationally binds a set of astronomical objects that revolve directly or indirectly in an orbit around a single star known as the Sun.
The star concentrates 99.86% of the mass of the solar system, and most of the remaining mass is concentrated in eight planets whose orbits are practically circular and transit within an almost flat disk called the ecliptic plane. The four closest, considerably smaller planets, Mercury, Venus, Earth, and Mars, also known as the terrestrial planets, are composed primarily of rock and metal. While the four furthest away, called the gas giants or “Jovian planets,” more massive than the terrestrial ones, they are composed of ice and gases. The two largest, Jupiter and Saturn, are made mostly of helium and hydrogen. Uranus and Neptune, called ice giants, are made mostly of frozen water, ammonia, and methane.

Historically, traditional ecology has dealt with the study of natural processes in a vertical sense, that is, analyzing ecological processes without reference to the spatial relationships of the system under study. Furthermore, ecologists have made efforts to locate their sampling sites in homogeneous areas, to obviate the noise produced by spatial variation. However, since a couple of decades, it has been generally accepted that this noise is an integral part of the natural ecosystem, and that the processes vary spatially and temporally (Matteucci and Colma, 1998). Since the inclusion of spatial and temporal factors, then, landscape ecology has emerged, a transdisciplinary science by definition that considers spatial heterogeneity as a core causal factor in ecological systems.

To talk about vision and emotions and neuroesthetics, which is, after all, where we encompass all this perception and the emotions it evokes, and the mechanisms we have in the nervous system to seek pleasure through manifestations artistic and pleasurable experiences in general, it is good to go back to the origins of vision. Why has vision played such a predominant role in humans (and hominids in general)? It seems that it has a lot to do with the upright position. When hominids reach the bipedal position, when they climb trees, of all their senses, the one that has the best chance of offering them advantages for their survival, for their adaptation to nature, is sight.

- Report
Water stress, essentially measured as water use based on available supply, affects many parts of the world. More than two billion people live in countries suffering from water stress (United Nations Organization, 2018). However, physical water stress is often a seasonal rather than an annual phenomenon, as exemplified by seasonal variability in water availability. An estimated four billion people live in areas where they experience severe physical water scarcity for at least one month each year (Mekonnen and Hoekstra, 2016).
It is also worth noting that around 1.6 billion people face “economic” water scarcity, which means that even when water is physically available, they lack the necessary infrastructure to access it.

VV.AA., Not just with weapons
The collective work Not only with weapons / Non solum armis. Culture and power in New Spain* Born from the symposium “Culture and Power in New Spain” framed in the XVIII International Congress of Ibero-American Anthropology, organized by the Autonomous University of San Luis de Potosí and the University of Salamanca in March 2012.
As usually happens with this type of work, the articles it incorporates address very heterogeneous topics and, apparently, without much relation to each other. However, all have as a common denominator the study of some of the instruments —military, cultural or religious— used by the Spanish or by the New Spanish society to exercise power over their members. Each chapter, independently, studies a feature or characteristic element of the time such as the language, burial mounds, rosaries, civil architecture or religious festivals, among others.
*Published by the Iberoamerican editorial Vervuert, April 2014.
