Preventing Water Damage: Capillarity, Filtration, Condensation
Capillarity: Basic Techniques to Prevent Water Damage
Filtration
Phases:
- Wetting and saturation (the larger, the slower the rate of suction). Slow and fast.
- Sheet as texture and superficial “adsorption”.
Penetration Routes:
- Porous structure
- Construction seals (flat, angled)
- Expansion joints
- Joint practices
- Breaks (cracks, fissures)
Water Tightness:
- Exposure level
- Façade geometry (angles and corners)
- Physical properties of materials (suction and absorption)
Drainage:
Depends on:
- Tilt of horizontal planes.
- Flaps on
Natural Environment: Resources, Hazards, and Policies
The Natural Environment as a Resource
1. Relief as a Resource
The relief of the Spanish mainland provides resources and is related to human activities:
- Influences settlements
- Plays a role in farming
- Provides mineral and energy resources
- Impacts communications
- The peculiarities of the terrain can be a tourist attraction
The coastal relief is unfavorable for the installation of ports due to the predominance of rectilinear forms. Fishery resources are impacted by the narrow width of the continental shelf.
2.

Earthquakes: Causes and Effects
An earthquake (from the Greek σεισμός, tremor) is a shaking of the ground produced by the collision of tectonic plates and the release of energy in the course of a sudden reorganization of the crust material to overcome the state of mechanical equilibrium. The most important and frequent earthquakes occur when the stored elastic potential energy is released in the gradual deformation of rocks adjacent to an active fault plane. However, they can also occur from

Romanesque Art: An Introduction
Romanesque art flourished during the 11th and 12th centuries. It represents the first international artistic style in Europe. The Romanesque is the culmination of a series of trials involving pre-Romanesque styles, incorporating Byzantine and oriental influences. The Benedictine order, particularly the Monastery of Cluny, played a crucial role in the creation of this style. They intervened in organizing pilgrimages, which facilitated the creation and diffusion of Romanesque

**Central Nervous System**
The central nervous system is formed by the encephalon and the spinal cord. They are protected by the skull and the spinal column, respectively.
