Abstract
Nowadays in many large industrial enterprises, one of the motivational incentives for hiring employees, as well as for encouraging them, is the provision of temporary or permanent use of residential real estate. This raises the question of choosing the best option of the property from a variety of proposals on the market. This article addresses the issue of estimating the value of residential property in the city of Krasnoyarsk. The descriptive signs of the apartment were not only its internal parameters, such as the area or number of rooms, but also the external characteristics that describe the environment of the apartment house. The data on the apartments were taken from the website of the apartment sales announcements and from various open data sources. The number of organizations of each type considered within a radius of 1000 m serves as a quantitative measure of the house environment. The model built using a random forest showed good results and solved the problem. The relative error of the forecast was 8%. In addition, it was shown the positive impact of the apartment external characteristics on the quality of the constructed model. As a result, an easily scalable model was built that can be applied to other cities.

Abstract
The implementation by small innovative enterprises of the LBR technology for household wastewater treatment, which is a complete cycle of urban wastewater treatment (WWTP), is one of the most perspective direction of strategic development of the regional economy, improving the parameters of its investment, environmental and social components. Each technological stage of technology is carried out on separate devices located indoors - a technological process of a closed hardware type. Such a process lends itself to automation, since each of the devices is technologically autonomous and can be replaced by another due to a malfunction or according to technological indications. In this way, high process stability and flexibility are achieved. All devices are of serial factory manufacturing, which ensures high quality, aesthetics and reasonable price parameters, as well as, if necessary, the ability to upgrade each unit individually. The hardware type of the technological process, being high-tech, energy-efficient and environmentally friendly, creates the prerequisites for a significant reduction in sanitary protection zones (2–6 times) and areas allocated directly to sewage treatment plants (7– 8 times). In addition, it becomes possible to flexibly change the capacity of WWTP (increase or decrease if necessary), as well as introduce purification stages necessary for specific conditions or remove unnecessary ones, without compromising the integrity of the technology and the efficiency of wastewater treatment. Implementation LBR technology by small innovative enterprises maximum environmental, social and economic efficiency and at prevent the waste of investment resources.
Impact of drought on dust storms: case study over Southwest Iran
Authors: Javadian Mostafa , Behrangi Ali , Sorooshian Armin 
Published: November 2019

Abstract
Dust storms are common meteorological events in arid and semi-arid regions, particularly in Southwest Iran (SWI). Here we study the relation between drought events in Iraq and dust storms in SWI between 2003 and 2018. The HYSPLIT model showed that central and southern Iraq are the main dust sources for SWI. Mean annual aerosol optical depth (AOD) analysis demonstrated that 2008 and 2009 were the dustiest years since 2003 and there is an increased frequency of summertime extreme dust events in the years 2008 and 2009. The Standardized Precipitation Evapotranspiration Index revealed that drought in Iraq significantly affects dust storms in Iran. Similarly, dramatic desiccation of Iraq wetlands has contributed to increasing fall dust events in SWI. AOD in SWI is highly correlated (−0.76) with previous-month vapor pressure deficit (VPD) over Iraq, demonstrating the potential of VPD for dust event forecasting.

Determining the optimal wells density grid for low-permeable reservoirs
Authors: Donskikh D A 
Published: November 2019

Abstract
The share of oil contained in low-permeable reservoirs increases, the average size and oil reserves of the discovered fields decrease, the main geological and physical parameters of productive strains deteriorate. Accordingly, for low-permeable fields, the choice of the development system and the optimal density of the grid of wells is one of the main issues. In addition, the problem of optimizing the density of the grid of wells is related to the implementation of enhanced oil recovery methods. In the field, where the well grid density is not optimized, the application of high-tech methods of enhanced oil recovery will not be effective. Thus, the purpose of this work is to substantiate the effective density of the grid of wells for low-permeability reservoir conditions.

Published: November 2019

Abstract
The optimization of peat production makes it a priority to re-equip the peat industry with new and modernized equipment based on energy efficiency and energy conservation. One could construct more and more new stations and increase energy production by exhausting resources, but one could come up with fundamentally new technologies and energy systems through the accumulation of energy in advanced energy-dense materials and related systems. In other words, it is more reasonable to replace today’s end user with much more budget-friendly and safer energy systems. The systems, as such, should be reliable and easily repairable.

Published: November 2019

Abstract
The reservoirs of tank farms and oil storages are structures of increased fire danger, the accidents in which lead to severe economic, environmental and social consequences.
The article details the cause of tank fires during the repair work. One of the ignition causes is bitumen mastic, used for waterproofing foundations and walls of the tank. Increasing the autoignition temperature makes it possible to increase the fire safety of vertical steel tanks. For this purpose, work was done to add various binders to the bitumen mastic.
The results of calculating the self-ignition temperature of bitumen and limestone mixture, the results of calculating the autoignition temperature of bitumen and pumice mixture, and the results of calculating the autoignition temperature bitumen and sodium salt mixture are presented. As a result of the estimation of the self-ignition temperature of bitumen with additives, the addition of limestone is the optimal way to reduce the fire hazard of waterproofing on the bitumen base of the foundation of vertical steel tanks for oil storage.
To verify the reliability of the autoignition temperature values obtained by calculation, laboratory studies were carried out for a mixture of bitumen and limestone.

Abstract
The possibilities of increasing the efficiency of separating coal from the massif by improving the pick alignment schemes of shearer cutting drums are considered. Given the existing structural limitations of the radial extension of the picks and the thickness of the cuts, an increase in efficiency is achieved by using combined series-group schemes for arranging picks, including energy-efficient cutting, paired and group with a larger cross-sectional area of the cuts and, therefore, with a larger particle size of the separated coal fragments, reduced dust yield and specific energy consumption.

Published: November 2019

Abstract
The article deals with the problem of reduction of the level of pipeline vibrations caused by resonance with disturbing frequencies of pumping units. Each pipeline vibration has to be analyzed since there are no universal methods for reducing pipeline vibrations. For vibration isolation, it is proposed to use vibration isolators on the basis of negative rigidity. The pipeline acts as a stabilizer for a vibration isolator becomes flat which reduces its rigidity and natural frequencies. Analytical calculations were performed to confirm the effectiveness of the solution. A passive vibration absorber based on the elastic element moving along the guides perpendicular to their axis creates power characteristics which are required to protect against vibrations.
