Land administration system in Slovakia is a large system. Many incomplete data and errors have been incorporated into its content since 1850. Most problems in the field of land administration system are solved by judicial proceedings, in which the expert testimony is required to reach the conclusion. The gathering of data about a particular land parcel consists of investigation of documents and maps. The investigation of map documents is very important for the whole process. The derivatives of these maps are store...

A weekly measurement of the parameters of the indoor environment was carried out in the building of the day rehabilitation centre in order to verify the state of the indoor environment, to determine the processes that create the indoor environment and to define the factors that affect the resulting state of the indoor microclimate. One of the important factors is...

Waste management is a current and future challenge due to the increasing volume of waste. The amount of waste generated directly correlates with production and consumption patterns. The current level of natural resource utilization exceeds the Earth's capacity for replenishment. Therefore, humanity must take action to mitigate the consequences of rampant natural resource consumption. One way to achieve this goal is to increase the level of waste recycling. However, the amount of waste actually recycled is signific...

Today about 10% of Latvia's territory is occupied by peatlands (645,100 ha), but the extraction of peat happens in only 4% (25,739 ha) of the total. In regulatory documents peat bogs are mentioned as having a very high probability of flammability (in the context of climate change and other natural elements: drought, heat, lightning and deliberate or unintentional human activity). This indicates the need to improve fire safety by conducting research and improving regulatory frameworks. The aim of the study was to a...

Even today, factories and production systems are primarily planned using established methods from lean production, developed in the 1990s, which only partially address sustainability. Industrial production significantly impacts climate change; in Germany, for instance, 70% (9.1 million TJ) of the primary energy requirement of 13 million TJ comes from industry, and around 28% of annual new land use is attributed to industrial expansion and new construction. This situation is no longer viable, given the European Com...

Nowadays, the use of supercomputing for solving almost any task ranging from industrial to the ecological ones has been increasing. It should be noted that this requires lots of energy, which negatively affects the environment and is costly. However, in a number of cases it is possible to achieve high performance calculations without the use of supercomputers but instead by relying on special processors, focused on a particular class of tasks. While optimizing the computational pipeline for a particular mathematic...

Forest ground vegetation biomass plays a significant role in carbon (C) storage and contributes to the overall carbon pool of forest ecosystems. Ground vegetation, including understory plants, shrubs, and grasses, not only affects carbon sequestration through photosynthesis but also contributes to the carbon cycle as it decomposes and release carbon into atmosphere and soil. This process adds to soil organic matter and affects it carbon dynamics. Understanding the above and below-ground biomass of forest ground ve...

During the mining, handling, and processing activities, the production of fines is inevitable due to breakage of large particles caused by compression, abrasion, attrition and impact of the ore particles with one another and the equipment during beneficiation and handling. The fines generated as a result, are generally high-grade feed stock materials and add value to processes. Many attempts to recycle these fines have shown some limitations because of the quality of binders used for agglomeration. Pyrometallurgic...

Dynamic climate changes require large human action. One of its essential elements is the reduction of anthropogenic GHG emissions. Within the European Union, they constitute one of the two fundamental goals of the European Green Deal strategy, which assumes that Europe (EU) will remain the first climate-neutral continent by 2050. Among the nine sectors of the economy the most widely covered by these activities is the energy sector. Taking into account the assumed rate of GHG emission reduction, it seems that trans...

Gypsum composites are promising building materials, but they have disadvantages such as low strength and water resistance. To improve these properties, a self-reinforcement method can be used, where the gypsum matrix is reinforced with crystals other than gypsum. One type of such crystals is ettringite. To obtain a self-reinforced gypsum composite, it is necessary to maintain a high pH environment and sufficient ions to form ettringite. In this work high-calcium fly ash, which is a waste product of coal combustion...

Most rivers in the temperate zone experience flooding due to snowmelt or heavy rainstorms. The lower Danube rivers has caused significant economic damages and in some cases even loss of human life. Understanding the relationship between the occurrence rate of Danube rivers flood events and climate change is crucial for flood risk management in Romania. Here we present a multiproxy and observational data set of floods from the lower Danube Basin Rivers over the last millennium. The results highlight that the lower ...

In this work, the ionic composition of formation water of three oil deposits (C2vr, C2b, C1pr) was studied. The study of these deposits holds both practical and scientific interest. Due to their complex geological structure, they are difficult to develop. Productive deposits are characterized by the presence of widespread unconsolidated zones with high vertical and horizontal fracturing, high layered heterogeneity, the absence of significant regional reservoir-seal rock, and difficulties in cross-well section corr...

Hydrological droughts are formed by different processes, but how strong and heterogeneous they are, leading to different manifestation and characteristics of the droughts. Droughts have no distinct starting date, but different methods gives a course of action that may help to identify dry signals and possible drought conditions for early warning. We choose hydrological drought indices that are applicable for Bulgarian conditions. Using statistical methods, minimum flow, deficits and spatial characteristics can be ...

On the background of regional climate changes, an increase in the frequency and intensity of extreme droughts has been observed in many regions of Europe in recent years, and this trend is expected to continue in the future. While common in southern Europe, including Bulgaria, drought can adversely affect human life and economic activities. Extreme droughts lead to water scarcity, restricting the availability of irrigation water for agricultural purposes. In the regions where irrigation is vital for sustaining cro...

In 2023, 18.3 GW of new wind energy conversion capacity was installed in Europe; most of them (79%) represent onshore capacities. Most of this energy production is achieved with horizontal axis wind turbines. For this type of turbine, the location of the transmission coupled with an electric generator or a hydraulic group, in the turbine platform, leads to a significant increase in the mass of the platform, and implicitly in the mass of the pillar that supports the turbine. In addition, turbine maintenance becomes...

The seismic hazard in Polish copper mines has remained continuously at a high level, generating a relatively large number of accidents and negatively affecting the continuity of the exploitation process. To minimize the threat, a number of preventive actions are taken to reduce the ability of the rock mass to accumulate stresses, which should ultimately result in a reduction in the number and energy of seismic phenomena. Unfortunately, as previous experience shows, the effectiveness of preventive measures is sever...
