This article analyses the environmental impacts arising from the construction and operation of warehouse complexes and their effects on the landscape and the environment. Warehouse complexes are a key component of the logistics chain in modern industry, but their construction and operation can significantly negatively affect the surrounding environment. The article examines various aspects of these impacts, including land occupation, changes in landscape, emissions, and waste management. It discusses options for prevention, elimination, and compensation of negative effects, as well as current legislative and methodological approaches to assessing the environmental impact of warehouse complexes. The aim of the article is to provide a comprehensive view of the issue and identify potential measures to mitigate the environmental impacts of warehouse complexes

The dispersion and deposition of solid particles in turbulent flows within sewer networks were numerically analyzed. Given the high density ratio between solid particles and water (greater than 0.1), observed in the semi-arid regions of Algeria, the added mass forces and pressure gradient were integrated into the particle motion equation. A coupled Euler-Lagrange approach, based on the 𝑘-𝜔-𝑆𝑆𝑇 turbulence model and the Discrete Random Walk (DRW) model, was used to simulate fluid flow and particle transport, as well as their interaction with turbulence. The pressure gradients from the numerical simulations of turbulent flow were compared with experimental data from the Dyn- Fluid laboratory at ENSAM Paris, showing excellent agreement. The simulations revealed that pressure drop increases with particle size and higher flow velocities. They also showed that particle deposition rates correspond to known deposition zones in sewer networks, and that an increase in water velocity reduces particle deposition, in line with scientific literature.

The future of waste disposal, which represents a major ecological and environmental problem in Europe and its individual countries, is still not solved in any effective way. Landfilling is directly related to the waste management programs of individual countries of the European Union, which mainly strive to mitigate the impact of waste on the environment. Improper handling of waste poses a threat to all components of the environment, therefore proper handling and subsequent processing is essential.

In today's Europe, passporting is mainly carried out by private landscaping companies, which offer their customers a complete appreciation of their property on the market. From the private sector of individuals, this is not a frequent phenomenon in our country. In the Czech Republic, this trend is limited mainly by the financial situation of the majority of the population. These services are thus used in the state sector by the administration of parks and greenery, which must keep records of all costs of maintaining public greenery.The inventory of greenery is discussed abroad mainly in connection with forest management, which, in contrast to orchard evaluation, broadens its horizons to other attributes, including substance flows, soil erosion, the amount of biomass and the amount of excavated material. With the growing consumption of wood and the global problems related to this issue, the ecological value of greenery, which is often introduced into legislation, is being emphasized in EU countries, but also in the Western world.The thesis focuses on the passportization of vegetation greenery in the Šenov Chateau Park. It deals mainly with a new method of evaluation, which consists of calculations using a professional calculator prepared by the Agency for Nature and Landscape Protection. Furthermore, this thesis deals in detail with the changes that have taken place since the last inventory within the revitalization of the Castle Park, which was carried out by Ing. Petr Ondruška. At the end of the thesis, there is a map and a proposal for further care. Lists of taxa can be viewed in the appendices, which are a guide for the entire evaluation.

Photovoltaics are currently experiencing a huge boom in Europe. European policy is focusing on the deployment of renewables in the energy sector and the electrification of the European vehicle fleet. This article focuses on comparing the efficiency of different types of materials and technologies in the construction of PV panels and briefly summarises current technologies for recycling PV panels after the end of their productive life. One of the panels compared was part of a field measurement and its values are partly reported by the manufacturer, partly measured and partly calculated. The other values for the sample of materials used are obtained from scientific literature or annual reports of the manufacturers. The article shows that the original average values of 10% to 20% efficiency of PV panels are still shifting, and some materials and technologies now allow efficiencies of up to 38%. High hopes are especially placed on perovskite materials, GaAs cells, or combinations of these with other materials.Unfortunately, we have not made much progress in the recycling of photovoltaic panels and, with minor modifications, the methods already used for the first generation of photovoltaic panels are still used. These are mainly the mechanical method, the chemical method and combinations of these.

From tennis through volleyball to athletic sports, clay plays important role as subsoil. The bulk material, clay, is cheap, because it is recycled product made at low cost by crushing bricks and clay tiles. Due to its compressibility and friction properties, it is an ideal material to produce clay courts. Therefore, friction parameters, compressibility factors and flowability were investigated. These mechanical-physical properties are also important for the practical handling of these materials, such as storage and transport of the material. For this purpose, three basic types of clay powder were characterized and compared. Experimental work was performed using Schulze RST-01 rotary shear tester, Powder Rheometer FT4, laser particle analyzer Cilas 1190 and particle analyzer CAMSIZER. Shape analysis of the samples was also performed. The subject of the research was how the volume changes depending on the applied normal stress, and the dependence of the internal friction angle. Initial results showed that variations in the shape and size of the clay particles can cause differences in the behavior of the tested powders.

Extreme flood events are commonly described by several dependent characteristics, such as duration, volume and peak flow. In Algeria and North Africa, flood frequency analysis is conducted as a univariate approach focusing separately on each single of flood characteristics. The analysis of flood in oued Mazafran catchment by the flood frequency analysis is crucial for understanding and managing flood risk, designing infrastructure and planning for floodplain management. To perform flood frequency analysis, the series of the annual maximum flow discharge of Fer a Cheval station is fitted to a probability distribution. Well, several probability distributions can be used to fit this series such as Gumbel, Log Normal, Log Pearson type III, and more. The Choosing a single distribution probability has become an important question in hydrology frequency analysis. Therefore, the use of the decision support system that is based on the heavy tails of distribution probability analysis conducts to the use of sub-exponential distributions and information Criterion to the Gumbel distribution for this analysis.

In this study, load bearing capacities of screw bolts as a new friction bolt type was investigated carrying out a series of laboratory studies. New screw-type friction bolts with sharp threads were inserted into holes drilled in various soft rocks by applying rotation. Screw bolts and split sets inserted in different soft rock types were investigated to comparatively evaluate their load bearing capacity values. According to the results obtained from this study, new screw bolts were found to supply better load bearing capacity values than those of the split sets. Although the split sets are quite popular friction bolts used in rock engineering, they have significant disadvantages resulting from their poor anchorage performances in soft rocks. By making grooves on drill hole contact surfaces, increased coefficient of friction and load bearing capacity values can be supplied by new screw bolts which were found to be advantageous for using in soft rocks.

Dendrological research investigating the influence of anthropogenic and natural factors on the dendroflora was carried out at six post-mining sites: the “Halda Ema”mine dump, part of the Terezie tailings, the slopes of the Petr Bezruč mine dump, the Mokroš wastepond, the DarkovSeaarea and surroundings of Loucké ponds (Ostrava and Karviná regions). The reference area was a mixed deciduous forest in the Landek NNMin Ostrava. Our research findings confirm that anthropogenic and natural factors have a significant influence on the distribution and composition of woody flora in post-industrial sites. We noted significant differences in biodiversity between reclaimed areas and naturally regenerating areas, which points to the need for targeted management and conservation strategies to support the sustainable restoration of these landscapes. The highest levels of biodiversity were found at the "Halda Ema" mine dump, suggesting that site-specific characteristics are key to supporting species diversity. The results underline the importance of long-term monitoring and analysis of the influences that shape the woody flora in these areas, and emphasize the need to integrate ecological, social and economic aspects into the regeneration process. Variability in thebiodiversity of woody plants between individual locations was revealed, with the greatest diversity at the "Halda Ema” dumpand part of the Terezie tailings. Our study also reveals a higher prevalence of native plant species over invasive species in most of the monitored sites, which may reflect favorable ecological conditions or effective management strategies that prevent the spread of invasive species. These patterns, which agree with previous studies, suggest that ecological factors including habitat preference and human influence play a critical role in plant community dynamics. These findings expand our understanding of the process of landfill succession and the factors influencing biodiversity, reinforcing the importance of an integrated approach in ecological and environmental research to inform conservation and management practices.

Algerian phosphates are the most exploited mineral resource and are considered an important source of foreign currency and a vital element in the mining sector. However, phosphate waste must be valorized for the product to be marketable. Phosphate waste, treated through washing and calcination, meets industrial requirements and international standards, with a P2O5 content of 31 %. Various tests of calcination and washing of phosphate waste are carried out to thermally dissociate the carbonates of the exogenous and endogenous gangue from the ore within a temperature range typically between 700 and 1000 °C. To reduce the proportions of CaO and MgO compared to P2O5, the second important step involves hydrating the oxides of Ca and Mg to subsequently remove them.

To reduce the proportions of CaO and MgO compared to P2O5, the second important step involves hydrating the oxides of Ca and Mg to subsequently remove them. According to this study, it can be concluded that the calcination and washing method can be applied to phosphate waste, as it has increased P2O5 content. This technique is simple and cost-effective and does not require heavy investments in industrial equipment.
