In order to determine the impact on the working environment and the effects of pollutants on human operators, numerous measurements were made using an experimental stand in a forge, machine building, equipped with heating furnaces, treatment furnaces, mechanical presses, oxyacetylene flame cutting equipment and mechanical saws. The paper presents the equation of technological material balance with inputs and outputs corresponding to the process of hot forging of different semi-finished products and the main pollut...

The paper presents the need for the purification of polluted air from the highly polluting processing technology of an industrial shop. (paint shops, foundries, welding constructions, forging, etc.). The advantages of using ultrasounds in the pollutant air filtration and purification process and an ultrasonic filter designed are presented. The main computational and construction elements of the ultraacoustic system used in the design of the air filter are presented in the paper. Paper insists in the design of the ...

The solving of the project of the Ministry of Agriculture of the Czech Republic dedicated to sustainable agricultural management in the North Western Bohemia is under way from 2015 to 2018. The Brown Coal Research Institute is the main participant of the project. This article briefly summarises new results of the research of the Most Basin localities restoration problems. The main attention is devoted to the research of experimental areas founded in different dump localities with different dump rocks and different...

Maize (Zea mays L.) is the most important cereal after wheat and rice grown widely throughout the world, playing a major role in human diet or as livestock fodder. Water and nitrogen are the most limiting factors for maize grain yield and it is important to evaluate the response of maize crop to irrigation associated to N fertilization in order to obtain high yields and to prevent nitrate pollution. In this context, it was designed an experiment with the main purpose to analyze the variability of yield potential a...
