All of this are necessary to ensure the sustainable (balanced) development of the state, which seeks a harmonious and responsible approach of the state and society to the landscape and spatial planning. Therefore, in this work, the author examines how landscape typological units are distinguished in different areas. Examining the works of different authors, it can be observed that often different and similar features of the landscape are chosen in order to distinguish taxonomic units. Also, even when distinguishing territorial units of a landscape with the same taxonomic level, the features identifying this unit do not always coincide. Therefore, it is necessary to harmonize landscape cognition practices in order to achieve a balanced landscape knowledge. The aim of this work is to contribute to the knowledge of the landscape. To achieve this goal, the following goals were set: 1. To perform literature analysis; 2. To determine the diversity of landscape features by distinguishing landscape typological units; 3. Identify the most commonly used landscape features; 4. To present the classification of landscape features according to the typological units of the landscape. The following methods were used in the work: literature analysis, cartographic analysis, database analysis. Therefore, in order to harmonize the practices of landscape typological cognition, at first it should be defined which landscape features are considered essential. In other words, it is necessary to clearly distinguish and identify those features that are the most popular and provide the most information about the landscape itself. Thus, the aim of this work is to present the diversity of these features and to present their possible classification depending on the taxonomic units of the landscape to which they are assigned\"","PeriodicalId":329177,"journal":{"name":"GEOLINKS Conference Proceedings","volume":"9 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122435274","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}

This work proposes one such model obtained by using modern Machine Learning algorithms, and the results are compared with standard models such as ARIMA obtained for the same data. Using Machine Learning can produce software models ready to run with hardware using much lower specifications than those used for model training which is not the case for standard statistical models. The merged dataset in the analysed period (2006-2016) from the tide gauges along the Romanian Black Sea Coast is consistent and satisfactorily used to develop and validate a Seasonal Regression Integrated Moving Average and Machine Learning model for sea-level forecasts.

The diameter at 1.30 m from the ground and the total height of P. halpensis individuals were measured on 6 plots along an altitudinal gradient. The height structure shows that trees in the height classes between 5 and 10m have a very high density, indicating low natural regeneration. The total structure indicates that smaller trees are more abundant than larger trees (17.5<d≤27.5cm).

The increasing complexity of the mineral composition of the ore leads to the fact that the existing beneficiation methods and regimes do not provide the necessary quality of the obtained concentrates. This study shows the peculiarities of nepheline recovery from apatite flotation tailings of apatite-nepheline ores with low nepheline fraction. Two reagent regimes were tested for nepheline reverse flotation: a mixture of pine and foliate tall oil, a mixture of tall oil and polyalkylbenzene sulfonic acid, which previously showed high selectivity of separation of nepheline and dark-coloured minerals. On the studied apatite-nepheline ore samples the necessary selection of flotation separation was not observed. Mineralogical analysis shows that losses of nepheline with froth products occur both at the expense of nepheline in intergrowths with associated minerals and at the expense of liberated minerals. Nepheline is quite actively floated, which is associated with a change in the surface properties of the mineral. The quality of flotation nepheline concentrates is reduced due to liberated grains of amphiboles, pyroxenes, and mica. The high content of feldspar in the ore, which during flotation predominantly remains in the chamber product, also affects the quality of the nepheline concentrate. It was possible to increase the Al2O3 content in the concentrate to the required values only after magnetic separation in a strong field.\"","PeriodicalId":329177,"journal":{"name":"GEOLINKS Conference Proceedings","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115164646","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 pollutant can appear as a result of leaks from the transport pipelines, the damage of the oil extraction and processing installations, and the distribution states of the petroleum products. In the vast majority of interventions to combat pollution, polymeric sorbents are used which are spread over the pollutant and then washed with warm water. This technology does not completely clean the pollutants, and the polymeric sorbents are difficult to remove. Oil-cake (sunflower) is a grated residue after oil extraction and contains the amino acid lysine and high content of fiber and methionine. At a quantity of 100 kg of sunflower seeds, a processor obtains a quantity of 35 kg of residual mass consisting of a sunflower meal. This product can be used as a sorbent for petroleum products, being then used to produce green energy. The physical properties of two sorbent substances (sunflower oil and peat) are presented. Also, their adsorption capacities for four pollutants specific to the oil industry (gasoline, diesel, paraffin oil and sulfur oil) are analyzed, as well as the adsorption kinetics.

Feldspar consumption has been gradually increasing in ceramics, glass industry for solar panels, housing, and building construction. Feldspar raw materials include intrusive, effusive rocks, weathering crust of crystalline rocks, sedimentary altered and altered rocks, as well as partially medium and basic aluminosilicate rocks. It was defined an industrial application for each species of feldspar. Potassium feldspars (orthoclase, microcline, sanidine) are used in electroceramic, electrode, abrasive, and ceramics industries. For these productions, the potash module is fixed in a ratio of 2: 1. For some industries, in particular the manufacture of high-voltage ceramics, the necessary feldspars are as close as possible to pure potassium (with a modulus of at least 4: 1, which corresponds to 80% of the orthoclase component). Potassium-sodium raw materials, from a potassium modulus of at least 0.9, are used for building construction. Sodium minerals with non-standardized potassium modulus are used for the glass industry, the production of enamels, and products such as vitreous porcelain. Calcium feldspars, represented by plagioclase of higher numbers, have limited practical application and their presence in feldspar concentrates is undesirable. According to mineral associations, all types of feldspar raw materials can be divided into five types: 1) feldspar (syenites, trachitis); 2) quartz-feldspar (pegmatites, granites, sands, etc.); 3) nepheline-feldspar (nepheline syenites, alkaline pegmatites); 4) quartz-sericite-feldspar (shales, secondary quartzites); 5) quartz-kaolinite-feldspar (sands, alkaline kaolins, secondary quartzites). It is shown on the example of Ukrainian deposits of feldspar minerals that complex deposits with by-products become the main source for production. Especially if these are new mining operation facilities. The authors have identified three main types of such complex multicomponent deposits: 1) deposits of intrusive rocks where weathering crust of crystalline rocks are mined as a byproduct; 2) complex deposits, where feldspar rocks are enclosing or overburden and can also be considered as byproducts; 3) deposits where feldspar concentrate can be produced as a product of ore components processing.\"","PeriodicalId":329177,"journal":{"name":"GEOLINKS Conference Proceedings","volume":" 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120828854","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}

Among the most devastating fungal diseases of peanuts are Cercospora arachidicola, Puccinia arachidis, Sclerotium rolfsii which cause substantial loss of production. Loss of yields due to the incidence of peanut disease may be up to 50%.

This synchronization is necessary in order for the measurement results to be linked to actual space and time coordinates as accurately as possible. The same measurements taken at different times may give different results due to changes in the orientation of the Earth relative to the Sun and Moon, as well as for other uncontrollable reasons.
