Authors: Strzalkowski Pawel 
Published: November 2019

Abstract
The publication presents a statistical analysis of workplace accidents in Polish mining in 2009-2017. Collecting and studying information on accidents at work is essential element necessary to improve the organization of work and to introduce preventive activities that will reduce the probability of the workplace accident. The analysis was based on the data of the Statistics Poland and the State Mining Authority. Based on the collected data, it has been shown that the number of workplace accidents and persons injured in these accidents in the studied years decreased and amount to 30% (according to the Statistics Poland) less in 2017 than in 2009. Whereas, the incidence rate of accidents at work (defined as the number of injured people per 1000 persons employed) in Polish mining ranges from 13.97 (in 2013) to 17.82 (in 2010) and is twice higher than the incidence rate of workplace accidents for all industries in Poland. The accidents at workplace in the mining industry in the analysed period occured on average every 137.88-223.43 thousand Mg of mined minerals. Additionally, the causes of workplace accidents and the number of persons injured were analysed depending on the age of the persons injured, length of work seniority, specific physical activities performed by the persons injured at the moment of workplace accident and the type of injuries. The highest number of accidents at workplace is related to inappropriate behaviour of a person at work and workplace accidents were most often suffered by persons injured aged 20-49 years (89.47%), who performed different activities at the moment of an accident at workplace: movement (31.46% persons injured), handling of objects (20.22% persons injured), carrying by hand (19.91% persons injured) and working with hand-held tools (13.26% persons injured). The most frequent types of injuries suffered by persons injured at the moment of accident are wounds and wounds and superficial injuries (34.05%), fractures of bones (30.12%) and dislocations, sprains and strains (20.91%).

Abstract
Agricultural territory planning is the omitted item of land management in Bulgarian legislation. This causes unofficial, chaotic and non-holistic use of the Agricultural Territory with future negative consequences for farm, regional and state economy development. The objective of this study is to present a concept for strategic and on-farm planning of the Agricultural Territory and to suggest changes in legislation. Documentary analysis of normative, strategic, historical and other documents in respect of spatial and land-use planning has been conducted, including the National Strategy for Regional Development 2012-2022 and the National Concept for Spatial Development 2013-2025, Ordinances of the Council of Ministers, acts of Municipal Services of Agriculture, Analytical Reports on sustainable agriculture management on municipal level, land use plans and maps. Quantitative and qualitative methods for collecting and processing economic, geographic and statistical information were used. The paper presents an outline of a modern Agricultural Territory Development Concept (ATDC). Approaches for long-term strategic land planning on municipal level and short-term land planning on farm level are proposed. ATDC offers completion of Spatial Development Plan on municipal level with details of Agricultural Territory; includes recommendatory development zones that are based on the natural recourses distribution, quality of land and zoning of agricultural production in the country; outlines regimes and optionality of the territorial elements and development zones. The Concept gives general characteristics of a Land Use Plan (instead of Specialized Detailed Development Plan) and its territorial elements on farm level. As a result of the study, amendments to the regulatory framework are proposed too.

Abstract
The behavior of the disordered systems in the conditions of the strong compression attracts particular interest in materials science. Natural impact glasses, being with a metastable state, can keep features of the structure for millions of years, form essential volumes compare to experimentally possible high-pressure products. The complex analysis of geological, mineralogical-petrographic, petrochemical features and degree of crystallinity of tagamites, vein glasses and vitro-clastic formations of the origin type of melt impactites of the Kara astrobleme including their phase state composition have been studied. The melt Kara impactites have dependence on the initial character of the melted sedimentary target and cooling velocity of an impact melt. The lowest order has been described for ultrahigh pressure vein-type glasses which contain silica drops with single crystalline coesite and firstly found melt-crystallized high pressure variety of smectite. The vein melt impactites consist of solidified impact melt presented by totally amorphous alumina silicate glass with augite microcrystallites and ultrahigh pressure silica glass with coesite microcrystals and “drops” of firstly found melt-crystallized high pressure variety of smectite. The boundary between alumina silicate and silica glass is characterized with liquated amorphous Fe-rich drops. The special feature of the studies melt impactites is low alteration in spite of 70 Ma age and high content of water. The large volumes of an impact melt created massive tagamite bodies have longer cooling underwent with the almost complete crystallization. The obtained data indicate the specific nature of melt glasses of vein type and prospects of their further research for fundamental study of amorphous state under ultrahigh pressure and propose new materials.

Abstract
The article presents the possibilities of using time-domain reflectometry (TDR) to determine the water content and electrical conductivity of mineral soil with biochar addition. The TDR method consists in measuring the time of electromagnetic pulse transmission and reflection from the obstacle back to the source point. The impulse is a step signal of voltage. The reflected signal contains information on the dielectric properties of the material being tested. Therefore, qualitative, and quantitative properties of the material can be detected. The tests were carried out using a mobile reflectometric device as an electronic humidity and conductive meter. Based on the obtained results, the usefulness of reflectometric methods in the study of the water content and electrical conductivity of mineral soil was determined.

Abstract
According to the standards ISO 6184/4 and EN 14373, the efficacy of explosion suppression systems is estimated by maximum reduced (suppressed) shock wave overpressure, recorded in a suppressed explosion event. In addition to this, a significant interest is the capability of explosion protection systems to reduce the dynamic loads on the human body. This task is not considered in standards. The G. Tsulukidze Mining Institute has been studied mitigation of dynamic loads on human by water barrier, generated using the protective system. The system composed of a blast detector, a wireless device for activation and an absorber. During an accidental explosion, the proposed system immediately forms a protective water barrier in the zone to be protected to reduce the overpressure generated by a shock wave. A prototype model has been manufactured, installed and tested under real explosion conditions in the underground experimental base of the G. Tsulukidze Mining Institute. An anthropomorphic test device Hybrid III 50th was used during testing. To register dynamic load generated during an explosion, 7 sensors were installed in different zones of the dummy. Tests were conducted both with the use of the protective system and without it, in conditions when the charge weight was 2 kg, and the distance from the charge to the dummy was 8,5 m. Comparative analysis showed that the protective system, which contains one absorber (may contain several absorbers), reduces the dynamic loads generated in different zones of a human body by 30-50%.
Adsorption of Lead on Agricultural Land at Žitný Ostrov (Slovakia)
Authors: Kovacova Viera 
Published: November 2019

Abstract
Heavy metals are important environmental pollutants threatening the health of human populations and natural ecosystems. Like other inorganic and organic contaminants, the fate of heavy metals in the environment is largely controlled by sorption reaction with soil colloids. The ecological effects of heavy metals in soils are closely related to the content and speciation of the elements in the solid and liquid phases of soils. In connection with the possible binding mechanisms of heavy metals in soils, the concept of specific and non–specific adsorption was discussed. Recent results have indicated that the adsorption of heavy metals on the soil particles is not only restricted to the formation of surface complexes but can also take place in the interior of minerals. Heavy metal sorption by the organic residues at all concentrations was very high. A positive relationship between the rate of adsorption and dosage was obtained indicating that the adsorption process was influenced by increasing the dosage of the residue as well as the shaking period. The sorption data obtained were fitted Freundlich and Langmuir isotherms out of which the Freundlich adsorption model was found to have the best fit for Pb. Movement and attenuation of heavy metals in soils are among other processes controlled by sorption onto the surfaces of soil particles. Processes like precipitation/coprecipitation, complexation and competitive effects of other cations may also influence the attenuation, but in all cases, sorption will be involved, and at natural and slightly polluted concentration levels sorption may be the predominating attenuation process. The Pb sorption on ten investigated soils from the Žitný ostrov area (Slovakia) has been studied in laboratory conditions. The aims were the estimation of adsorbed amount of lead S, determination of adsorption parameters for several soil types (L1, L2, L3, L4 loam soils, SL1, SL2, SL3, SL4 sandy-loam soils, CL5 clay-loam soil, C6 clay soil) and comparison of the obtained results with the results introduced in publishing works. Batch adsorption experiments were performed with a very wide range of lead concentrations (0,01-500 mg/l Pb2+) at a constant soil/solution ratio. The parameters KF, n of Freundlich isotherm and parameters Qmax, KL of Langmuir isotherm were determined experimentally.

Authors: Malinowska Miroslawa 
Published: November 2019

Abstract
The characteristics of extreme precipitation, including dominant trends, were analyzed for eight stations located on the Polish coast of the Baltic Sea for the period 1951-2010. Maximum 1-day and 5-day precipitation totals, events exceeding the 90th and 95th percentile calculated for the period 1961-1990 applied as indices enabling the assessment of the frequency of wet conditions. Annual trends were calculated using the standard linear regression method, while the fit of the model was assessed with the t-test at the 95% confidence level. Annual precipitation reaches values from 775 mm on the east coast to 683 mm on the central coast and shows positive trends on six out of eight analyzed stations, from 0.8 mm·year-1 in Swibno to 2.5 mm·year−1 in Dziwnow. The maximum 1-day precipitation totals range between 58.7 mm on the western coast to 105.0 mm on the central coast and show statistically significant trends (0.1 - 0.2 mm·year−1) in this area. There are, on average, six to seven 5-day rainfall periods recorded annually in the investigated area. The annual number of 5-day precipitation periods shows positive statistically significant trends in the central and eastern part of the South Baltic coast (0.2-0.3 per 10 years). The median of the maximum 5-day precipitation totals ranges from 21.6 mm in Swinoujscie to 78.6 mm in Ustka. Trends in changes in maximum 5-day rainfall totals reach the level of 0.1-0.2 mm·year−1 and are statistically significant in stations from Swinoujscie to Ustka and in Gdynia. The values of the 90th percentile of 1-day precipitation total are equal to 8-10 mm. Annually, there are about 16-18 days with such precipitation recorded in the area under investigation. The trends are positive (0.1-1.0 day per 10 years) on the central coast. The values of the 95th percentile of 1-day precipitation totals reach 11.5-14.0 mm. Annually, there are about 8-9 days with such precipitation recorded in the area under investigation. The trends are positive (0.3-0.4 days·10 years−1) on the western and central coast.
Next Generation Sequencing Data and its Compression
Authors: Carpentieri Bruno 
Published: November 2019

Abstract
Over the past few years the amount of digital memory and network traffic used by sequenced biological data has increased dramatically. Genomic projects such as HapMap, 1000 Genomes, etc., have come to the collection and description of genomes of 2,504 individuals from 26 populations, and they contributed to exponential growth of databases of this type and to the development of increasingly efficient technologies. Thanks to the large-scale sequencing of samples of DNA, the interest and the new research in these areas by the scientific community are suddenly grown. In a very short time researchers have developed hardware tools, analysis software, algorithms, private databases and infrastructures to support genomics. In this paper we analyse different approaches for compressing digital files generated by Next-Generation Sequencing tools containing nucleotide sequences and we discuss and evaluate the compression performance of generic compression tools such as gzip and bzip2 by confronting them with a specific system that was designed specifically for genomic file compression: quip.
The traces of Mining in Lubsko (western Poland) - proposal of the geotouristic path
Authors: Kaczan Wojciech 
Published: November 2019

Abstract
Lubsko is a city in the Lubuskie province (western Poland) with a population around 15 000. The use of raw clay minerals in this region has its beginning in the Middle Ages. Through the years the production has changed to the centralised mining industry. The end of this branch has begun in the late 1980s due to the political changes in Poland. Nowadays, the signs of this significant history of the city are ruined or in bad conditions. The reason for organising geotouristic path is to protect the geoheritage of this region, mainly old open-pits and the infrastructure. Proposed stops will teach about the mining heritage in Lubsko, the geology of the glacial region, the processing of raw clay minerals and various usages of this material. Moreover, connecting both didactic and recreational use may give the chance to integrate touristic sites in the city. The development of such a path may attract tourists from Poland and Germany, which may result in an improvement of the financial situation of Lubsko. Considering the possible benefits and obstacles the SWOT analysis is presented in the article.
About the Microstructure of the Graptolite Periderm - Examples from the Holy Cross Mountains (Poland)
Authors: Morga Rafal 
Published: November 2019

Abstract
Graptolite reflectance is one of the main parameters for assessing thermal maturity of pre-Devonian rocks in which vitrinite does not occur. However, microstructure of the graptolite periderm has been known only recently, and still little is known about low-reflectance graptolites. The purpose of the work was to determine microstructural features of the graptolite periderm in the oil window shales and compare them to those known from the previous studies, in which more matured organic matter was investigated. Four samples were collected in the Holy Cross Mountains (Central Poland), in two localities (Bardo Stawy and Prągowiec ravine). Reflectance (Rr) measurements as well as micro-Raman analysis were carried out on the sections parallel to the bedding. Micro-Raman analysis was performed on unpolished surfaces to exclude influence of polishing on microstructure. The obtained spectra were curve-fitted using four Lorentzian (G, D1, D2 and D4 band) and one (D3 band) Gaussian lines. Graptolites (Rr=0.70-0.77%; Vitrinite Reflectance Equivalent VRE=0.67-0.72%) occur in the Silurian dark grey clay shales of the Llandovery (Bardo Stawy) and Wenlock - Lower Ludlow (the Prągowiec ravine) age. Graptolite periderm represents poorly organized carbonaceous material, which is inferred from the occurrence of the D3 and D4 bands, and overlapping D2 and G bands. Microstructure does not vary significantly between the samples from the two considered localities (the exception being the D1 band FWHM), which corresponds to the narrow range of graptolite reflectance. Compared to the Raman spectra obtained from graptolites with higher reflectance, the G peak is significantly moved to the lower and the D1 peak to the higher wavenumbers. The FWHM of the G band is higher, while the ID1/IG ratio usually smaller. Taking into account the results from the previous study, it can be concluded that in the reflectance range of 0.7-1.8% the G band position first moves to the higher, and at Rr>1.2% to the lower wavenumbers, while the D1 peak gradually shifts to the lower wavenumbers. The G band FWHM decreases with increasing graptolite reflectance, which reflects improvement in structural ordering, while the ID1/IG ratio starts to increase at Rr≈1.5%, indicating the growth of the coherent domains within the graptolite periderm.

Abstract
Knowledge of soil erosion and runoff processes leads to changes in attitudes towards a rational use of soil. Agricultural practices have a wide range of negative environmental impacts, including accelerated soil erosion, degradation, and increases in the volume of surface runoff. It is, therefore, necessary to investigate these negative influences on arable land. The study area is the municipality of the village of Vrbovce. It is situated in the north-western part of Slovakia in the White Carpathian Mountains. Due to its specific geological (heterogeneous rock masses of flysch) and geomorphological conditions (hilly country, uplands), that part of Slovakia is prone to accelerated soil erosion and mud flood formations. Nevertheless, a significant part of the municipality of Vrbovce is classified as agricultural land. The aim of this study is the soil erosion and runoff volume modelling that is focused on changes in the land cover/land use. We calculated soil loss with the Universal Soil Loss Equation (USLE) for agricultural parcels in the cadastral area of the village of Vrbovce. We are offering a set of suitable measures and agricultural procedures for this area as a result of our research. We estimated the direct runoff for the Teplica River basin up to the Teplica water gauge and five ungauged subcatchments in the cadastral area of the village of Vrbovce (Haluznikov creek, Lulovský creek, Zahutník creek, Zápasečník, and an unnamed creek). The Teplica river is poorly gauged with only a 10-year observation period. That length of hydrological measurements is not enough for the required period for calibrating a hydrological model. We used 3 modifications of the curve number (CN) method for estimating the volume of the direct runoff with various return periods, i.e., the standard CN method with values for the current land use, the worst land use an alternative, and the DesQ program method. We also applied the Pearson Type III distribution for the estimation of the peak flow with a higher frequency of occurrence for the Teplica gauging station. The results of the specific runoff were compared with the values of the specific runoff calculated for the Sobotište water gauge, which is situated downstream of the Teplica river. The results show that the most suitable modification of the CN method is the standard CN method with the use of the values for the current land use. The predictions of the long-term average annual rate of erosion on each parcel from the land parcel identification system (LPIS) were calculated by the Universal Soil Loss Equation (USLE).
