Active layer of permafrost

-

Active layer - the depth of seasonal defrosting of the subsurface layer in areas where we observe the presence of long-term permafrost. It was found that the variability of the thickness of the active layer of the permafrost is largely due to local factors such as vegetation cover, mobility and type of water, and surface exposure. Research directions

In the studies of seasonal defrosting (frost), three research directions are distinguished: Methodology of research

The main method used for conducting this type of research is periodic (seasonal or monthly), probing the thickness of permafrost active layer on selected sites. Each of the values ​​included in the analysis includes the following information: date, location of the probing (location, geomorphological situation), soil temperature, description of the soil to be defrosted and its condition.

The earliest mention of these creatures is dated to the fifth century BC, and its author is Herodotus. According to her, these ants inhabited the deserts of Persia and India and extracted gold from their sands. Several such creatures were kept in the residence of the King of Persia. Gold was to be obtained by caravans made up of several camels in the heat of the day, when the ants were protected underground. You had to do it quickly, because the ants sensed the smell of people and went on the pursuit, and they were deadly dangerous. This story is confirmed by the next accounts: Nearchos, one of the army officers of Alexander Macedoński, and Megastenes - a historian and traveler. The fragment of the Megasthenes (IV-III century BC) preserved in fragments can be seen in the underground mines at the foot of the mountains on the easte...

Names of streets and squares

The names of the streets and squares were originally of a topographical nature, that is, they informed about: Researchers propose two names for these toponyms - urban or plateonimy. S. Urbańczyk points out that the older names were spontaneously formed and sprouted in the daily lives of the inhabitants of the place. The information contained herein was related to the characteristics of the place (eg appearance), important road directions (geographic orientation) or values, functions and economic meanings called places / objects in the settlement for the inhabitants' lives. Former names are protected by law, but are often not respected by managers of the municipality, county or province. Currently the names of streets and squares are given by the commune authorities, county governors or voivodships. There is a tendency to use commemorative names, ie to commemorate deserving people and important events (eg Zygmunt August Street, 3. Maja Street). The names of the districts are ...
