The aim of the study was to assess the level of contamination of soil with strontium, rubidium and scandium in the solid waste deposits. The study was performed on soil samples collected from Moldova Noua, southwest of Romania, an area with historical anthropogenic history. The soil analysis was performed using X-ray fluorescence (XRF). The samples were collected from five collection points using a random pattern from around the illegal waste deposit and all analyses were performed in triplicate. To assess the influence of wastes on the soils concentration levels of strontium (Sr), rubidium (Rb) and scandium (Sc), were calculated contamination factors (CF), and pollution index (PIL) by reporting the concentration of the investigated elements of the upper earth crust concentrations and geo-accumulation index (Igeo) calculated by reporting the elements concentration values to a control sample, used as reference. The reference sample was collected from an area close to the waste deposit but located in a protected green area. The results show that from the investigated elements, scandium is the element of concern, the soil presenting a moderate contamination level with this element.

"The structure of various stands, defined as the diversity of trees in the stands, can be an indication of overall biodiversity and habitat suitability, be useful in predicting stand growth and provide stand details for forest inventories. In an effort to find sustainable resource management strategies, a study was conducted on the structural and ecological characteristics of stands in Chettaba forest (Algeria). In this study, six diversity indices were used to characterize the horizontal and spatial distribution of individuals in multi-species stands, using four plots, located in the Chettaba forest (East-North Algeria). The results obtained allowed us to note that P2 and P3 present similar average densities (600 feet/ha), the plots P1 and P4 present low average densities (250 feet/ha and 350 feet/ha). The average DBH values vary from 25.65 cm for the P2 stand to 30.61 cm for the P1 stand. The average basal area varied between 33.73 m²/ha (P3) and 18.92 m²/ha (P1). The Shannon and Weaver index reached its maximum in plot 4 with 8 species. The study allowed us to evaluate the floristic diversity of the forest. Moreover, it indicated the need for its integral protection for its dynamics towards a dense forest vegetation."
“各种林分的结构，被定义为林分中树木的多样性，可以作为总体生物多样性和栖息地适宜性的指标，有助于预测林分生长，并为森林清单提供林分细节。为了寻找可持续的资源管理战略，对Chettaba森林林分的结构和生态特征进行了研究(阿尔及利亚)。本研究以阿尔及利亚东北部Chettaba森林4个样地为研究对象，利用6个多样性指数对多物种林分中个体的水平分布和空间分布进行了研究。获得的结果使我们注意到P2和P3具有相似的平均密度(600英尺/公顷)，P1和P4地块的平均密度较低(250英尺/公顷和350英尺/公顷)。P2林分的平均胸径为25.65 cm, P1林分的平均胸径为30.61 cm。平均基底面积在33.73 m²/ha (P3)和18.92 m²/ha (P1)之间变化。Shannon和Weaver指数在样地4(8种)达到最大值。这项研究使我们能够评估森林植物的多样性。此外，它表明需要对其动态进行整体保护，以形成茂密的森林植被。”

"Intensive human economic activity has led to decrese in the natural resource potential of territories and qualitative changes in the natural environment surrounding a person: a violation of the spatial and functional structure of natural systems, a decrease in the biological diversity of flora and fauna, a deterioration in the quality of water and land resources, a decrease in the ecological and economic sustainability of technical and natural systems and the quality of human life. Ensuring the sustainable functioning and development of territories is possible due to the complex arrangement of the territory (scientific organisation of the territory). It is the optimisation of the land using structure that will restore disturbed ecosystems to standard values, increase biological diversity, environmental sustainability and economic efficiency of landscapes. One of the limiting factors in the implementation of this measure is the lack of an effective mechanism for assessing the effectiveness of investments in land development. All this indicates the need to develop proposals for the development of methodological approaches to assessing the environmental and economic efficiency of investments in land development, taking into account the shortcomings that we identified when analyzing existing approaches to assessing the effectiveness of investment projects of social significance. At the same time, it should be noted that ensuring sustainable development of territories is impossible with the existing nature-intensive concept of economic development. A new approach to solving this problem is needed, which should: • be based on a deep study of socio-economic and environmental problems, a retrospective analysis of the state of landscapes and a long-term forecast of the expected consequences of the impact of human activity on the state of individual components of the considered territory and the landscape as a whole; • it aims to ensure the socio-economic and environmental safety of Russia.

Aleppo pine plantations were studied in the region of El Hamimet, the diameter at 1.30m from the ground, the total height of P. halepensis individuals were measured on 4 plots according to an altitudinal gradient. The establishment and interpretation of diameter and height structures are essential for forest management decisions. Knowledge of these parameters is an essential step in their sustainable management. The diameter and height structures were established according to diameter or height classes. The stand on plot 4 is characterized by the lowest diameter and height values. The analysis of the diameter and height structures reveals an increase in the frequency of young individuals. These results contribute to the improvement of the knowledge on the indicators of the current state of the natural Pinus halepensis stands that can be used as a basis for the management of the El Hamimet forest.

This article has as a starting point the definition of the concept of ecological principles. Then, after classification of the principles of ecology (domestic principles and international principles), we present and critically analyze and compare the main principles in the field of ecology. Among the ecological principles on the domestic chain, we present and analyze 11 principles, namely: pollution must be combated at the source; the interests of environmental protection must be taken into account in all design or execution decisions; any exploitation or use of natural resources must be avoided if it is accompanied by damage; it is necessary to raise the level of scientific and technological knowledge, inter alia by supporting scientific research; the costs of preventing and combating pollution to be borne by the polluter; the activity of one state not to harm the environment of another state; during the elaboration of the community policy in the field of environmental protection to take into account the interests of the developing states; community environmental protection policy must be developed in the long term and protection must be comprehensive and international, which is achieved, inter alia, through cooperation within international bodies; the cause of environmental protection is everyone's responsibility and for this reason education is irreplaceable; depending on the source of pollution, the most appropriate level of action must be established taking into account the nature of the pollution, the necessary measures, the characteristics of the protected territory. This principle is defined as a "subsidiary principle"; it is necessary to harmonize and coordinate national policy in the field of environmental protection in accordance with the long-term commonly accepted directives. We also present and analyze the principle according to which environmental protection must be an essential element of the economic and social policy of the state.

The article, based on the current informational material, provides an overview of the mineral resource complex of Australia and the ways of its development in modern conditions. Modern requirements for the development of the fuel and economic complex of countries are caused by new challenges in connection with the need to follow the Paris Convention on Climate Change and the installation on decarbonization – a significant reduction and then a complete rejection of CO2 emissions from the combustion of hydrocarbons. The work shows that the process of "greening" Australia provides for the creation and implementation of a completely new paradigm for the development of the fuel and energy complex. This is a complete rejection of the extraction and use of coal, an increase in gas production in compliance with environmental requirements, the development and implementation of new technologies, the expansion of gas storage facilities and a network of pipelines, as well as the parallel development and introduction of renewable energy sources.

In Eastern Slovakia, due to extensive chemical production in the past, especially production of explosives, and continuing combustion of coal, toxic chemicals, PCBs, fly ash and other substances are stored in a tailing pond. The current state of the tailing pond and the surrounding area, as well as its impact on the environment is analysed. Based on the results of the analysis remediation of the tailing pond is suggested. The closure of the tailing pond, including stabilisation of the pond material and the treatment of the pond surface, is designed. The result of the study proposes two possibilities of the use of pond after remediation – for growing crops as biomass and for building of a recreation and regeneration centre. In both the proposals, their advantages and disadvantages were evaluated. Reclamation will take place through a combination of technical and biotechnical stages. These proposals would be a great plus and benefit not only for the tailing pond but also for the environment and the surroundings of the pond.

This article is aimed at comparing the effectiveness of testing the dimensional parameters of a tank wagon with an internal ribbing with a nominal volume of 85 m3 in a production plant. One of the used methods is the traditional volumetric method, ie measuring the volume of water with a pair of flowmeters when filling the vessel. The second method is a method of computer processing of data obtained by 3d scanning of the interior of the tank from several positions and the subsequent composition of the tank model and calculation of its volume using the PolyWorks program. Evaluation of both measurement methods revealed that despite the non-trivial internal division of the measured object, both methods are sufficiently accurate, and even in this case the scanning method provides the measurement result several times faster compared to the volumetric method. In the reported example, measurement time spent to achieve results for the scanning method was approximately one third comparing with that of the water filling.

"Nowadays we are witnessing an increased interest in phytotherapy and implicitly for herbal products that have lower side effects. One medicinal plant whose popularity has decreased significantly in recent years is Lythrum salicaria L., loosestrife, known in Romanian traditional medicine for its beneficial effects against gastrointestinal diseases. The aim of this study is to evaluate the biological activity of three different extracts (aqueous, alcoholic, acetonic) from the flower tips of Lythrum salicaria L. using the BSLA (Brine Shrimp Lethality Assay) test and the antimicrobial activity of the extracts on two reference bacterial strains which are important for the medical field (Staphylococcus aureus and Escherichia coli) through the diffusimetric method. We demonstrated the fact that the Lythri herba plant product extracts (aqueous, alcoholic, and acetonic) lack acute toxicity, as well as the moderate antibacterial effect on the Gram-positive reference strain, Staphylococcus aureus, thus highlighting the possibility of using the plant in biomedical applications."

The ecological consolidation of vegetation according to three classes of the UN soil cover (grass + shrub + trees) is considered. The ecological coefficient is calculated by dividing the share of vegetation by the share of changed land. For the rating, the forest-agricultural coefficient is convenient as the ratio of forest area to arable land. The ecological principle of the consolidation of 13 types of land is proposed, which makes it possible to carry out the ecological consolidation of the vegetation cover and altered human land. According to these proposed criteria, the ranking of the subjects of the Ural Federal District was carried out.
