The paper analyzes physicochemical properties of liquid products of waste tyre pyrolysis, and attempts to assess their usefulness as fuel for diesel engines. Every year, the number of produced vehicle tires increases at a very fast pace. Used tyres turn into waste that is difficult to manage simply because, according to relevant EU regulations, vehicle tires should be subject to recycling. To a large extent, the problem of waste tyres management may be resolved by their utilization through pyrolysis. The processin...

Terrestrial Laser Scanning (TLS) in LiDAR technology is a commonly used method in obtaining geometric information about objects. Individual scan stations can be combined into one project using the cloud-to-cloud method or based on targets (chessboards or spheres). Target-based registration with spheres is very convenient because in planar view always circle is visible, no matter of the angle of view. On the other hand, it is inconvenient to use the same size of spheres throughout the project. Large spheres are eas...

Of all geographically related health problems, pollen allergy is one of the most common allergic diseases of the respiratory tract. To support pollen allergy sufferers (including allergic rhinitis, conjunctivitis and asthma), a range of mobile applications are available for tracking pollen forecasting and recording symptoms. The geographic location of such records provides new opportunities for WebGIS pollen allergy monitoring. However, adding raw VGI data to a web map may produce more misinformation than benefits...

With the growing number of cars in Russia over the last years, the number of gas stations has several times increased, and the range of oil products has greatly changed. At present gasoline should provide reliable and efficient engine?s work; it mustn?t change its composition and characteristics during long-term storage; mustn?t damage reservoirs, fuel related components, industrial rubber articles; should have effective volatility and hydrocarbon composition; should provide non-detonating stable fuel combustion p...

In the present time an approach is widely developed when the rock mass is considered as an energy-active hierarchical-block medium. The blocks of this medium are constantly interacting with each other and exchanging energy under the influence of various factors. In the intact rock mass the energy dynamic equilibrium of the medium is maintained due to constant energy feeding and, at the same time, due to continuous processes of structural discontinuities destruction on different levels. The seismic energy frequentl...

The paper presents deformation of the housing and shaft reinforcement surveyed within the telemetry deformation monitoring system. Research was taken in the Salt Mine Wieliczka Museum, one of the most popular monuments in Poland, placed in 1978 on the original UNESCO list of the World Heritage Sites. Water leaking into Ko?ciuszko shaft posed a serious threat to museum and forced authorities to seal the housing with Jet-grouting method. Due to boreholes which were designed very close to the shaft, the material inje...

Different species of plant aphids can be found in greenhouses worldwide, depending on the crop and climatic condition. Aphids may occur in large colonies on new growth, the base of buds, or the undersides of mature leaves. The aphids damage the plants directly by sucking plant sap from the plant tissues and indirectly as a vector of different plant viruses. The aim of this paper was to identify the most abundant aphid species causing damages to pepper cultivated in greenhouses. The two year experiment (2015 and 20...

The lower horizon mainly consists of clays grading in the mineralogical composition from polymineralic, with fragments of slightly...

The primary aim of earthquake resistant design is to prevent building collapse during the seismic event, but severe earthquakes have a low probability of occurrence during the life time of the structure, therefore in contrast to traditional structural design in earthquake design, structures are permitted to work in post-elastic domain under seismic load. It would require a large lateral stiffness of the structure and an expensive resisting system to design the building to have an elastic response. Because of these...

The Cukar 2 east ore body represents the latest explored ore body within the Mucim Mine with possibilities to enter exploitation stage in near fututre. Calculated ore-bearing coefficient in the Cukar 2 east ore body was 0.40%, meaning that within the ore body boundaries 60% of mass is not mineralized somehow, which is compatible with remaining three ore bodies within the Buchim porphyry copper mine. The calculated value of variation coefficient (V) has shown value of 71.39% that is in the range of 43-100%, which d...

In the past decades, cities have become the engines of national economic growth. Globalization has a significant effect on urban areas, forcing them to compete for international business with other cities around the world and their countries. It is estimated that by 2050, more than 80% of the world?s population will live in urban areas. In order to meet the environmental challenges posed by this changes, cities will need to reduce pollution levels and use resources more efficiently. It will need reliable tools to ...

Historical buildings are a major part of European and national cultural heritage which people all around the world decided should be preserved for the future. In order to conserve both the construction elements and the thermal comfort, it is crucial to find the optimal configuration of the energy related equipment.

Research conducted on sterile dumps resulting from surface mining of lignite, have shown that in the waste dump restoration process, the main issues are raised by the non-uniformity of texture, extreme textures, lack of structure, low content of organic matter, the deficiency in macro (NPK) and micro (Cu, Zn, Fe, Mn) nutrients and low biological activity. Most experiments with fertilizers revealed that the maximum yield was achieved in variants fertilized with high doses of organic fertilizers, in addition with mi...

The drilling and investigation of the Kola superdeep borehole SG-3 for the first time provided direct data on the structure and composition of the ancient continental crust at previously inaccessible depths. Rock density and their anisotropy in elastic properties were used as the main parameters for the formalized description of the borehole SG-3 section and the reference profile on the day surface. The first parameter reflects the rocks' lithology, the second accounts for the intensity of synmetamorphic tectonic ...
