ABTOW

ABTOW (acronym for Automatic Water Toxicity Generator) - An automated biological water pollutant detector based on the nitrifying bacteria metabolic activity that is involved in the processing of nitrogen compounds. The device includes a serial connection of a measuring system consisting of a preparatory block, a measuring block and an analytical block through which the test water flows in turn.

The device tracks the metabolic activity of microorganisms by monitoring the oxygen content of the water flowing through the bioreactor. When water is clean, bacteria consume a lot of oxygen. When contamination occurs (eg lead, cadmium, zinc, phenol, potassium cyanide, aromatics or alcohols), oxygen consumption falls sharply, and electrochemical sensors react immediately and the results are automatically transferred to the appropriate service. The reaction time of the device to the presence of harmful substances in the water is about 90 seconds. A small amount of water (about 120 ml) is used in the test system, which is rapidly replaced (100 ml / min) and the stability of the system ensures free growth of the bacteria.

The device was created by the cooperation of an interdisciplinary research team of scientists from the University of Silesia. The University also owns industrial property rights for the invention (patent No. 206892). Uses and benefits

Thanks to the very quick analysis of water quality, the biodetektor allows for continuous monitoring. It can also be the first line of warning against emerging threats that may result in breakdowns or targeted actions in water intended for consumption. Another risk may be the presence of hazardous substances from natural sources (metal ions or radionuclides). The advantages of the device include remote control, auto-calibration and auto- control of the system.

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 ...
