Transversal pitch

-

Gradual transversal on the map from 1852.

Transversal pitch (sometimes erroneously complex pitch) - much more complicated than linear pitch, although its construction is based on it. At present it is not drawn on maps, and cartographers rarely redraw it, because in their work they use ready-made, engraved on the brass plaque size 250 × 40 mm. Most often have 4 finished scales of 1: 500, 1: 1000, 1: 2000, 1: 5000. It is best to start with a linear scale and set a base pitch of 10, 100 or 1000 m. Once you have constructed such a scale from its individual points, you should extend the perpendicular lines.

José René "Pupo" Román Fernández (died 1961) - Dominican general. Curriculum vitae In the Dominican history, when the dictatorial president Rafael Leónidas Trujillo was in power, Roman was his niece's husband and "third person in the state" (Trujillo and SIM Arturo Espaillata).

Ultimately, the conspiracy ended with the conspirators' defeat when Zacarias - chauffeur Trujillo - survived the presidential bombardment and handed over the drafts of the bombers and Arturo Espaillat informed Roman about the death of the commander - at the sight of Arturo Espaillata Roman revealed ...

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 ...
