Factors influencing the formation of land cover of Jalilabad cadastral region are one of the reasons for the diversity of soil formation processes in the area. Intra-zonal soils are subject to the laws of vertical zoning due to changes in the height of the area due to its geographical distribution. Despite the fact that the Jalilabad cadastral region does not have a very large area, its separate parts are characterized by differences in bioclimatic and biogeochemical characteristics. The article shows the analysis and geographical coordinates of the main soil types formed in the Jalilabad cadastral region on the basis of a large-scale land map, depending on the soil-ecological conditions. In order to carry out comparative and ecological assessment of soils, we have made land plots in the study area. Currently, the cut samples are in the laboratory stage for physical and chemical analysis in accordance with the methodology.

Definition Of

More than 95 % of the total housing stock in the Netherlands is connected to central sewerage systems and in most cases the wastewater is treated biologically. As connection to central sewerage systems has reached its economic limits, interest in on-site treatment of the domestic wastewater of the remaining premises is increasing. A large scale research programme into on-site wastewater treatment up to population equivalents of 200 persons has therefore been initiated by the Dutch Ministry of Housing, Physical Planning and Environment. Intensive field-research work did establish that the technological features of most on-site biological treatment systems were satisfactory. A large scale implementation of these systems is however obstructed in different extents by problems of an organisational, financial and/or juridical nature and management difficulties. At present research is carried out to identify these bottlenecks and to analyse possible solutions. Some preliminary results are given which involve the following ‘bottlenecks':-legislation: absence of co-ordination and absence of a definition of ‘surface water';-absence of subsidies;-ownership: divisions in task-setting of Municipalities and Waterboards; divisions involved with cost-sharing;-inspection; operational control and maintenance; organisation of management;-discharge permits;-pollution levy;-sludge disposal. Final decisions and practical elaboration of policies towards on-site treatment will have to be formulated in a broad discussion with all the authorities and interest groups involved.

The article analyzes the results of statistical processing of morphometric and agrochemical indicators of zonal soils of the Republic of Tatarstan based on the accumulated information of large-scale soil studies. The boundaries of genetic horizons are examined, the content of humus and its reserves within the limits of heavy loamy and clay varieties of arable soil subtypes is estimated. Arithmetic averages allow us to generalize the humus content in soils. So, in the series of sod-podzolic soils – light gray forest-gray forest – dark gray forest-podzolic chernozems – leached chernozems-typical soils in a layer of 0-30 cm on average contains 2,20; 2,58; 3,76; 4,76; 6,8; 7,6; 7,2 % humus. The observed patterns of humus accumulation in soils are also preserved in the distribution of its reserves – 85; 97; 140; 162; 233; 257; 240 tons per he-1. It is proposed to characterize the general population along the boundaries of typical values that fit into the 50% confidence interval to assess the overall range of spatial variability of humus indicators. The upper limit of the typicity will correspond to the greatest accumulation of humus with a combination of local features of soil formation factors and can serve as a guide for predicting carbon sequestration in the soils of this region. Accordingly, the carbon-sequestering potential of sod-podzolic soil and typical chernozem is-20 tons per he-1, light gray forest soil-22 tons per he-1, gray forest soil and leached chernozem-27 tons per he-1, the highest values in dark gray forest soil are more than 30 tons per he-1

Diffuse pollution, caused by direct discharges from individual houses, small built-up nuclei, farms, camp-sites, etc., for which connection to central wastewater treatment systems is unfeasible, may be significantly reduced by on-site treatment. Based on a large scale research, including intensive field-research work on 14 systems of different types and sizes in a range equal to population equivalents (p.e) of 5 - 200 persons, 8 different types of system were compared. The comparison involved technological features, such as removal efficiency, reliability, operational and maintenance aspects, environmental impacts and land claims, together with economical features showing significant differences. Advantages and disadvantages of each system are highlighted to enable a selection of suitable systems to be made. When no limiting factors are present, it was found that - in general-infiltration systems (infiltration pits; infiltration trenches) have the best features for on-site treatment up to 100 p.e. For larger capacities, or when infiltration is not possible, the rotating biological contactor will be the best solution mainly because of the lower costs.

Abstract. Seismic active faults are closely related to earthquake disasters. Active faults determine the location and magnitude of destructive earthquakes. Therefore, strengthening active fault investigation and research is one of the main ways to reduce earthquake disasters. Airborne LiDAR, as a measurement method that can quickly obtain large-area and high-precision DEM results, can not only obtain structural distribution features of large-scale study areas on a macro scale, and determine the location and trend of active faults, but also be used to identify microstructural landforms and take researches on fine geomorphic structural features. In this paper, based on the detailed introduction, analysis and summary of the technical schemes, data processing and application of the airborne LiDAR technique in the northern margin of the Qinling Mountains and the Huashan Piedmont Fault Zone, it was demonstrated on the basic methods and technical advantages in seismic active faults and geomorphological research work of the airborne LiDAR technology, and a new and efficient method for seismic fault study was provided.

The use of energy contained in biogas is an interesting alternative to reconcile renewable electric power generation to environmental sanitation. Among the technologies used for recovering energy from biomass, the anaerobic digestion demonstrates ability to treat solid waste and effluents. This research work aims to analyze the influence of physical and chemical factors on the performance of anaerobic digestion reactors and to perform the characterization of biogas in order to assess their quality. The substrate evaluated is the mixture of liquid waste coming from different industrial processes and poultry manure. The characterization of CH4, CO2, H2S and O2 was performed daily in two reactors, R1 and R2, for a period of three months, and the physical and chemical parameters were analyzed biweekly. The parameters analyzed are carbon (C), nitrogen (N), biochemical oxygen demand (BOD), pH, total (TS), volatiles (VS) and fixed solids (FS). Among the results, stands out an average removal of 76% in relation to BOD and H2S concentration of 156.01 for R1, and of 91.64 ppm for R2, and the CH4:CO2 inverse relationship of 3.15 for R1 and 2.98 for R2, during the monitoring period.

Unmanned aerial vehicles (UAVs) are a relatively new technology. Their application can often involve complex and unseen problems. For instance, they can work in a cooperative-based environment under the supervision of a ground station to speed up critical decision-making processes. However, the amount of information exchanged among the aircraft and ground station is limited by high distances, low bandwidth size, restricted processing capability, and energy constraints. These drawbacks restrain large-scale operations such as large area inspections. New distributed state-of-the-art processing architectures, such as fog computing, can improve latency, scalability, and efficiency to meet time constraints via data acquisition, processing, and storage at different levels. Under these amendments, this research work proposes a mathematical model to analyze distribution-based UAVs topologies and a fog-cloud computing framework for large-scale mission and search operations. The tests have successfully predicted latency and other operational constraints, allowing the analysis of fog-computing advantages over traditional cloud-computing architectures.

Highlighting the sandy soil of Oltenia Plain calls for a better knowledge of their variability their correlation with major natural factors from each physical geography. Pedogenetic processes specific sandy soils are strongly influenced by nature parent material. This leads, on the one hand, climate aridity of the soil due to strong heating and accumulation of small water reserves, consequences emphasizing the moisture deficit in the development of the vegetation and favoring weak deflation, and on the other hand, an increase in mineralization organic matter. Relief under wind characteristic sandy land, soil formation and distribution has some particularly of flat land with the land formed on the loess. The dune ridges are less evolved soils, profile underdeveloped and poorly supplied with nutrients compared to those on the slopes of the dunes and the interdune, whose physical and chemical properties are more favorable to plant growth.Both Romanati Plain and the Blahnita (Mehedinti) Plain and Bailesti Plain, sand wind shaped covering a finer material, loamy sand and even loess (containing up to 26% clay), also rippled with negative effects in terms of overall drainage. Depending on the pedogenetic physical and geographical factors that have contributed to soil cover, in the researched were identified following classes of soils: protisols, cernisols, cambisols, luvisols, hidrisols and antrosols.Obtaining appropriate agricultural production requires some land improvement works (especially fitting for irrigation) and agropedoameliorative works. Particular attention should be paid to preventing and combating wind erosion.
