Mycelium cords home

Mycelium cord '- a bundle of parallel hyphae of fungus, clearly different in its structure and complexity from the remaining hyphae. The hyphae forming the outer layer of the mycelium rope are thin and thick-walled. They have a diameter of 2-4 μm, very low cellular light, and in their cell wall there is usually calcium oxalate. Internal hyphae, so-called the vascular hyphae are wide, thick-walled, and empty inside (without cytoplasm).

Mycelium cords have the ability to conduct carbohydrates and nitrate ions. Probably the factor that initiates the formation of mycelial cords is the availability of nitrogen. It was observed that they arise when nitrate ions are present in the substrate, but they do not appear in the substrate containing ammonium ions.

Ryzomorphs are a more complex structure than mycelial cords. Sometimes they are identified with mycelial cords.

Myrmex Indikos

Myrmex Indikos, pol. Indian ant - an alleged species of gigantic ants (according to Herodot's description, larger than foxes, but smaller than dogs). 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 ...
