The term symbol is used to refer to a reverential image. Normally it is painted on a level wooden board, although in Ethiopia, as in different conventions, materials, for example, metal or stone could also be used to create this type of image. The best known Ethiopian symbols have been dated in the fifteenth century and are mostly painted with rubber -based paint in wooden boards prepared by ESSO. The ethiopo symbols of this period normally represent the Virgin and the Child, the Apostles and St. Jorge.
The piece appeared here, which can probably dated the second 50% of the fifteenth century, correctly includes a mixture of subjects. On the left board, the child contacts his mother's jaw, an offer of delicacy that appears more often in works from this period onwards. The focal couple is flanked by two sacred messengers with swords without pinch that pass as their illustrious vigilant.
The right board is designed with images of the apostles who change their appearance in worship towards the Virgin and the Child. In the corner of the base, the right corner is a representation of Saint George riding a horse. The names of some of the figures on the correct board have composed in the lines that divide the scene into records. After all, the engravings that recognize the upper column of the apostles and the Virgin and the child were initially present at the upper edge of the two tables.
A site that has demonstrated especially support in the painting separated the effect of calculation and the different components is the Eel River Bowl river in northern California. There, scientists have planned approximately 200 slow avalanches and are currently reviewing 10 or so using instr. All these slides live in practically indistinguishable environments and environments; Only their sizes and shapes contrast.
In Eel River, researchers have discovered that few of each strange avalanche have a rainfall activation reaction: it can rain for a long time or months before there is development. The group has discovered that the creation of fine grain of these avalanches, unlike mathematics or the environment, has most of them to decide their behavior. "In general, fine grain soils with mud material have a slower reaction, and grain soils or beaters with huge breaks or cracks have a faster reaction," says Alexander Handworker, a geoscientist in the laboratory NASA Jet Propulsion in Pasadena, California.
However, organizing this data to make expectations will be a test. For a long time, geologists have been collecting information to more easily measure connections between the avalanche movement and the length and strength of precipitation. In any case, topographic materials and hydrological conditions are greatly factors, says Schulz, and the degree of accuracy that is expected to conjecture the slides continue to be the scope of the researchers. In addition, in numerous nations, the avalanche movement is strongly influenced by another wonder whose impact has not been completely examined: earthquakes.
