Often restoration programmes are based on simple plantation schemes, evenly planting trees that later on might contribute to economic activity. This, however, does not seem to be sufficient for supporting biodiversity. Recent research suggests that successful restorations should match original ecological patterns in any particular landscape, assuming that severe erosion and changing soil conditions have not taken place during disturbances. This means that understanding natural historic patterns is vital. However, achieving such understanding is often challenging, given the fact that historic satellite imagery is generally available only for relatively short time periods. It is therefore important, if possible, to model former landscape ecological patterns. Modelling might be based on different site-specific approaches and historical records. However, most powerful tools available today include deep learning and artificial intelligence. Construction and training of neural networks might allow simulation of historical forest patterns in cases when satellite imagery is not available for long time periods. Application of this technique is very likely to have important practical implications.","PeriodicalId":331146,"journal":{"name":"SGEM International Multidisciplinary Scientific GeoConference� EXPO Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122759879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The risk of dust explosions increases as more and more products take the form of dusts or require the use of dusts during manufacture. In spite of extensive research and development to prevent and mitigate dust explosions in the process industries, this phenomenon continues to represent a constant hazard to industries including manufacturing, using and handling of combustible dust material. \u0000The purpose of explosion preventing and protection measures is to prevent explosion occurrence, by eliminating or avoiding the conditions leading to explosions. The dust explosion and combustion characteristics are required to be known, in order to suitably choose and draw up the preventive and protection measures. Once known, the protection/prevention measures can be correlated with the safety characteristics. \u0000The aim of this paper is to analyze of explosion and combustion characteristics of wood dust clouds in dependence of the particle size distribution.

The circular economy is also based on the principle of 3R, Reduction, Reuse, Recycling and attempts are being made to implement this principle in all areas, in order to protect existing resources, which are limited. Unlike the economy of consumer goods where in time was used the principle of linear economy, where after manufacture and consumption the goods were disposed, in hydraulic drive principles were used and still used as reuse, repair, maintenance, factory. Due to the fact that hydraulic equipment is expensive to purchase new, and its maintenance is not cheap at all, market trends have always been to repair or reuse hydraulic components, to the detriment of their purchase by us. Practically, in this field of hydraulic drives, the beneficiaries turned themselves to these principles of the circular economy, without the need for them to be imposed by anyone, as has happened in other areas. The authors point out that in the field of hydraulic drives the importance of recycling and reuse has taken a significant place, so in this field it is much easier to successfully apply the principles of the circular economy, thus reducing raw material consumption and pressure on existing resources.","PeriodicalId":331146,"journal":{"name":"SGEM International Multidisciplinary Scientific GeoConference� EXPO Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122202038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has also been used as a baring capacity test for unpaved aircraft runways and other transport areas. Nowadays, CBR is used as a proof and control test in evaluating the bearing capacity of subgrade and structural layers of roads. A distinction is made between the laboratory test and the in-situ test, which is nowadays no longer widely used. This is due to several reasons. It is primarily about the physical demands of performing the test. Another limiting factor is that it can only be used in case of fine-grained materials. \u0000This paper deals with the development of an automatic lightweight dynamic cone penetrometer, verification of its functionality in the laboratory geotechnical field, describing the progress and results of comparative measurements with mechanical DCP.

The Blue growth strategy addresses this issue on a Pan-European level, fostering research and innovation with regards to marine environments. Building on the conceptual grounds of knowledge and innovation studies, we hypothesize that countries and regions within a common sea basin will achieve the highest efficiency in research collaboration and knowledge exchange. By using bibliometric data from the Scopus abstract and citation database, we track scholarly output, co-authorship, and citations in the framework of the Blue growth strategy affiliated to the institutions of the Baltic Sea basin. The visualization of the research landscape is done in VOSviewer software at the level of bibliographic coupling, cocitation, and co-authorship relations. Our study evaluates maritime research networks and knowledge flows between the coastal cities of the Baltic Sea basin countries.

For this reason, securing their supplies from import must be supported by a committed foreign policy as well as a sustainable raw materials policy in the field of their obtaining from domestic sources, both from mineral deposits, as well as secondary and waste sources. Raw material security must be based on the diversification of supply sources and minimizing supply risks. \u0000The results of analyses show that the European Union relies heavily on imported raw materials, especially in industries recognized as strategic (renewable Energy - wind & PV; grids, Li-ion batteries (LIB), electric vehicles (EVs), Robotics and defense). Moreover, most of the import sources are countries with high or very high risk of supply. Recently, these risks are higher due to unstable political situation in Eastern Europe. Taking into account above, the European Union should consider the possibility of further development of its own mining industry, based on its own resources. The raw material potential of European countries is significant, but recently problems related to the possibility of launching new mining projects have been increasing. Social, environmental and spatial conditions play a decisive role. In this context, particular attention should be paid to the properly implemented policy of mineral deposits safeguarding which provides access to primary sources of raw materials (deposits), thus reducing dependence from unstable import sources.","PeriodicalId":331146,"journal":{"name":"SGEM International Multidisciplinary Scientific GeoConference� EXPO Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128300326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monthly and seasonal values of precipitation amounts, number of days with different type of precipitation and mean air temperature from 6 meteorological stations in Vitosha and Stara planina have been used in this survey.

Increasing trend of the mean seasonal air temperature is also observed, however manifestly only for the highest regions where remarkable rising tendency could be determined in the beginning of the 1990-es.
