Mining is one of the most devastating forms of meeting human needs. As it is clear from the aerial photographs, the landscape of the north-western part of the Czech Republic is highly affected by the activity of the mining industry, namely lignite quarries. During the activities at these quarries, the landscape is transformed into a form that resembles the surface of the moon. For this reason, the law imposes an obligation on mining companies to reclaim the landscape after their activity to guarantee the higher cu...

Laser systems are widely used for measuring the most important physical values with the highest accuracy. In particular, laser measuring systems are used to identify earthquake precursors in monitoring tidal rock fluctuations. In many cases, signals from laser measuring systems contain noises that need to be filtered out. The signal component in this case has the form of a harmonic oscillation, the frequency and phase of which change and these changes carry information about the measured quantity. This signal shou...

Maintaining health and physical condition of astronauts during long-duration space missions requires measures to prevent microgravity effects. At present, such measures consist in practicing certain physical exercises, in using elastic suites, as well as in special medication. However, the efficiency of these solutions is limited. An alternative approach, technologically more difficult, but considerably more efficient, consists in producing a state of artificial gravity in the module inhabited by the crew. Such a ...

In the implementation of the characterization, i.e. the determination of the relevant mechanical and physical characteristics of the municipal waste landfill, it is necessary to define the optimal scope of the investigative works. The criterion of an optimum is determined by the minimum volume of planned actions with maximizing their performance. Generally, exploratory drillings give the so-called dotted data, with a regularly questionable quality of undisturbed and even disturbed samples. At the same time, they a...

From a structural optimization point of view, the design of steel lattice towers begins with choosing from various alternatives to develop the geometry of the incorporated trusses. The biggest challenge is to find optimal geometry based on experience. In contrast to some structures that are generally intuitive to construct, (e.g. common buildings structures), the same design for the tower structures is frequently built for several times. Thus, cost savings and performance improvements obtained by structural optimi...

A specific feature of thermal power plants (TPP) is the multivariate nature of their intense technogenic impact on the environment, including pollution of air, environmental waters, soils, as well as disturbance of the geologic environment. Besides, TPPs cause thermal, radiation, noise and electromagnetic pollution; they also induce physical littering of the terrain and problems associated with storage of ash waste. Due to the reasons stated above, a comprehensive study of environmental damage zones caused by TPP ...

One of the reasons for spontaneous combustion of coal waste dumps is the air intake into the body of a dump. Despite the measures taken to isolate the bases and dump slopes, spontaneous combustion of dumps occur in many countries around the world. That breeds a hypothesis that spontaneous combustion process is facilitated by placement of a dump in the geodynamically active zone of the earth's crust. In geodynamically active zone, due to its high permeability, the interaction of the dumps with environment occurs. P...

Article presents issues relating to the chances and curtailment of the use of planning concepts to shape mountainous areas, where development is based on tourism.

Recent flood showed that having no well-chosen planning concepts for upper river sections effect on damage and danger to human life in these places. The ...

The patchwork of land is one of the major factors that have a negative impact on the organization and the level of agricultural production. Excessive fragmentation reduces the intensity of work and increases the costs of agricultural production, thus generating lower and lower incomes. In terms of the unfavorable geometry of the boundaries of plots, resulting from the considerable fragmentation of land, the land patchwork plot is also an obstacle to building a cadastral system in Poland. The geodesy tool for impro...
