Environmental risk factors for environmental problems with physical, chemical and biological factors that cause or may cause health disorders as well as environmental degradation. One possible factor is noise. The World Health Organization (WHO) estimates that a target of 40% of the EU population is exposed to traffic noise of more than 55 dB and that more than 30% is exposed to levels of more than 55 dB at night. The issue of protection of the health of the population against the adverse effects of noise and vibr...

Operational monitoring of orchards is the basis for decision-making in management and correction of agricultural practices during fruits production. Especially important is the monitoring of phenological development of trees, which predefines agrotechnological operations, and fertilizers application dozes, and dates. The monitoring results as well can be used for forecasting fruit yield and planning fruit production and fertilizer needs. At present, operational monitoring of large orchards is practically not condu...

Active development of unmanned aerial vehicles has led to their widespread use for various purposes, and magnetic prospecting is no exception. UAVs in various modifications are used in aeromagnetic surveys intended for magnetic mapping of the subsurface. This allows to solve the problems of not only aeromagnetic prospecting (identification of ore deposits, petroleum prospecting, etc.), but also of geological engineering and archeology. The advantage of using UAV lies in the cheapness and safety of the survey. Magn...

This paper aims to explore the degree of intensification and extensification of agricultural practices followed by farms of different economic sizes and the type of farming in Latvia. While intensification is considered as an effective way of achieving agricultural independence at supra-national and national levels, more voices are raised against an increasing demand for energy and unsustainable agricultural activities causing irreparable damage to natural habitats and reducing biological diversity. Although farmi...

Large-scale changes can be observed in the Russian society in the XXI century. They laid the foundation to the Russian Federation integration into the global political, economic and cultural space, to the demarcation of a great number of borders as well as identified the indispensable necessity to uphold national interests of the state on a permanent basis. The processes of globalization, the development of international economic relations between the countries of the world community increased the need for competi...

Waste disposal and management is one of the urgent issues faced by mankind at the current stage of development. Waste car tires pose a significant threat to the environment, which makes their efficient processing particularly important, as the volume of this type of waste generated each year worldwide is estimated at more than 10 million tons, of which 1 million tons are produced in Russia. A review of the car tire, wood, textile, and plastic pyrolysis products is presented. The products of pyrolysis include pyrol...

The heat transfer from the source of initiation to the adjacent surfaces is a physical phenomenon worth considering in the process of analyzing the fire. This complex phenomenon describes how the transport, exchange, and redistribution of the thermal energy are carried out and is based on the theoretical knowledge that describes the initiation and fire evolution in time. Flames transfer heat from nearby surfaces through two physical processes, convection, and radiation. A third mode of heat transfer is conduction,...

In the national policy and development documents of Latvia, forest, along with other natural resources, is defined as an important strategic resource for the sustainable overall development of the country and the development of a diverse and export-intensive economy. At the same time, the need to exploit forests sustainably, reducing the risks to the quality of the natural environment posed by human activities, is emphasized by the documents. The research question is as follows: Are forests in Latvia overexploited...

There are many problems related to image processing and analysis that could be solved using convolutional neural networks (CNN). It's easy to implement CNN using one of thousand high-level programming languages. Such CNN will not be fast and energy efficient enough to be used in real-time systems. The good way to solve this problem is to use special hardware accelerators (neuroprocessors). The paper shows that it is possible to reduce the calculation time of the network using neuroprocessors. The implementation of...

Theoretical studies of how resource-based economies develop change along with changes in approaches to studying sustainable development. There are opposite points of view on resource-based economies. On the one hand, abundant natural resources help countries grow rapidly and efficiently. On the other hand, the 1970s saw the emergence of the resource curse concept in which natural resources are seen as an obstacle to successful economic development. This paradox is explained in various ways, including macroeconomic...

Spring-mass systems are known to experience vortex-induced vibrations (VIV) when exposed to viscous flows. These vibrations can be efficiently used for energy generation in ocean currents and rivers because significant power density can be extracted even from moderate flow velocities. The VIV generators typically include a large system of vertical or horizontal cylinders aligned perpendicular to the flow. The cylinders are connected elastically to a fixed frame and can oscillate independently. A recent comparative...

The construction of interfaces that satisfy the requirements of users is an important task since the interface is the ?face? and ?control panel? of the entire system for the user. The study aims to reduce the semantic gap between the user and the developer at different stages of the development life cycle of the user interface by using a understandable sign form, with which the meaning of the object will be formed at various stages of its design. From this point of view, the article presents the results of an anal...

Reservoirs are important hydraulic infrastructure for water use and flood control. Their impact on the hydrological regime of rivers downstream is significant. Accurate and reliable forecasting of flows in the rivers below the reservoirs is very important in cases of extreme meteorological events (heavy rains) for flood mitigation. The evolution of physically based hydrological models in recent years significantly improved the ability to describe and represent the hydrological processes at a basin scale. This pape...

The article describes the underground mining of compact ore bodies by inclined layer panels. (each sequentially developed bottom-up by means of inclined blind drifts). Compact ore bodies are opened by an inclined shaft equipped with a special hydraulic pipelines for delivery of fine-grained rock mass to the surface. In this case, the inclined shaft path, depending on the shape of the ore body, can pass from below the ore body, above it, or diagonally near its lateral surface. Directly from the side wall of the tru...

The article examines the relationship between the tasks facing geologists and the General state of the economy of the USSR and modern Russia. Since the end of the 19th century, geology has moved away from purely historical research of the Earth and is increasingly focused on the search and exploration of minerals and on merging with the mining industry. Given that the territory of the USSR and modern Russia has almost all types of minerals, it is most profitable to use the resources located on its own territory. H...

Carbonatites are a unique group of magmatic rocks that contain extremely high concentrations and the world's largest reserves of rare earth elements, niobium, and a number of other industrial metals. The Late Mesozoic Central Asian carbonatite province includes three main regions: Western Transbaikalia, Central Tuva in Russia, and the South Khangai region in Mongolia. The carbonatites form deposits and occurrences of the complex Fe-P-F-(Ba)-(Sr)-REE ores. We studied and correlated the present data about mineral an...
