Grawimorfizm

Gravimorphism - the influence of gravity on plant morphogenesis. It is one of the processes involved in growth correlation.

The term was introduced by Wareing and Nasra in 1958. This phenomenon is responsible for polarity and dorsal-abdomen observed mainly in young plants. As a result of receiving information about the direction of gravity, it is possible to produce roots only on the lower side of shoots. The same stimulus induces the formation of reaction wood in trees. In branches whose position is changed, the apex dominance disappears and further development takes place mainly in the upper part. The growth of branches lying horizontally is not stimulated even if the buds and shoots on the upper side are removed. Gravimorphism is also a process that affects the bloom.

Changes in morphogenesis occur as a result of hormonal regulation and modifications in the distribution of nutrients.

Pupo Román

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). He was the Minister of Armed Forces, a close associate of Trujillo, which did not prevent him from accepting Trujillo's murder in 1961 from the American consul in the Dominican Republic, Henry Dearborn. He led to the murder of Rafael Trujillo on May 30, 1961, but he could not use this to overthrow his followers. He failed to arrest them along with Trujillo's sons such as Ramfis. 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 ...
