3D plastic is a modern three-dimensional printing material that is very popular among home and professional 3D printers using layer-by-layer fusing technology (FDM). Today, in professional three-dimensional modeling, two main types of plastic thread are used - synthetic ABS and biodegradable PLA, which are converted into finished products in industrial FDM printers. Products from 3D printer are usually single-action models, which must be disposed of after use. However, synthetic polymers are not able to decompose ...

The paper presents the technology of controlling a beam made of the Polytech material. The innovative Polytech technology was used to construct buildings made from prefabricated units. The Polytech system requires analyses and verification of the detailed data related to the strength and deformability of the elements used for building construction.

It is known that the main reserves of diamonds in Russia are concentrated in the territory of the Republic of Sakha (Yakutia) and for many decades determine the volume of their production. Many years of experience in the development of open-pit diamond deposits have led to an excessive increase in the depth of the quarries, which creates the danger of working in the lower horizons, as well as an increase in the cost of production due to an excessive increase in overburden. The paper proposes the introduction of a ...

The agri-environmental policy of the CAP is not new to the EU. It has been developing for over twenty-five years, as agriculture is the sector directly dependent on abiotic and biotic environmental factors. On the eve of the new programming period (2021-2027), challenges in relation to the environment, climate and sustainable agriculture are increasing. In the context of deepening environmental changes, the risks to agriculture are limited to: changes in agricultural land; reduction of agricultural productivity; r...

Agriculture is the main source of ammonia emissions. It generates around 75% of global emissions of ammonia to the atmosphere and soil manure accounts for half of agricultural emissions. Ammonia emissions have a negative impact on ecosystems and human health, as it is able to accumulate both as solid particles and as an integral part of acid cases. Measures to reduce ammonia emissions can be divided into three large groups: the first group is ammonia-reducing measures in animal housing, the second group is ammonia...

The paper?s aim is to describe the chemical and physical characteristics of soils of the mixed forests. The...

This paper deals with the calculation of rock volume located in the hard-to-reach terrain of a water dam. During the reconstruction of the safety slip of the water dam, it was necessary to remove this rock and to determine the volume extracted at a particular stage of the construction. In addition, calculations of the total amount of rock above the given coordinates of the reconstruction project were solved. The reason was the need to know the amount of rock that still needs to be excavated to get the builders to ...

Besides the effective traffic management on sections of the road network, important for large cities and metropolises, the problem of eliminating the negative consequences from the delay points is topical. The delay point is the part of the road network on which the vehicle has to stop or slow down due to obstacles. The greatest difficulty is the fight against unforeseen delay points that occur on multi-lane roads at an arbitrary time in an arbitrary location. Examples of such delay points include traffic accident...

Operations conducted by petroleum industry generate a whole range of drilling waste materials. In oil & gas industry, the most common wastes consist of used oil or water-based drilling fluids, bore dusts, and cuttings. The chemical composition of drilling waste and its toxicity depend primarily on the geological and technological conditions of drilling, the type of drilled rock deposits, type and composition of the spent drilling mud and also on solids control equipment. Sustainable waste management became one of ...

The information system interface consists of various elements. Attention of the user decreases when working with a large amount of information. The authors suggest that it is possible to implement recommendatory (adaptive) modules for users, using changes in the graphical part of the interface. Such changes are called interface personalization. Personalization allows you to focus the user's attention on the most relevant elements of the user. To reduce the resource consumption of recommendation modules, it makes s...

The aim of this article is the possible impact of climate change on the components of water balance. Climate change has a non-negligible impact on the hydrological cycle and water resources. In this paper, simulated changes in the water balance in the selected river basins due to climate change were estimated using the WetSpa model. Distributed rainfall-runoff model simulations are often used to evaluate the impact of changes on the generation of runoff and water balance. The parameters of the model were estimated...

Tin is widely used in the electro-technical industry, mainly for the production of the solders and tin-sheets. Resources for the production of primary tin are currently limited. Therefore, the importance of secondary methods - the recovery of tin from waste - is growing. However, the recycling of tin is associated with many technological, economic and environmental problems. It is usually energy-intensive. One of the compromising methods is "dilution" - secondary tin is mixed with high purity primary tin. However,...

The deteriorated state of the environment with various degrees of devastation in individual regions is negatively implicated in the health status of the population and the quality of the ecosystem. Inorganic contaminants, especially potentially hazardous elements, are a serious problem in all environmental compartments. Heavy metals also belong to the priority inorganic contaminants. Many of them act toxic in the terrestrial ecosystem, even at low concentrations. Their toxicity consists of replacing essential meta...

The water supply of the majority of Estonian settlements and enterprises is covered by groundwater, only two cities, Tallinn and Narva, are using surface water as a source of domestic water. Approximately 89% of the residents of Estonia use water from the public water supply systems. The water abstraction in Estonia diminished constantly in the 1990s, reaching the level of 130 million m?/y. During the last ten years, water abstraction has been fairly stable - groundwater in the range of 45-50 million m?/y and surf...
