Abstract
Exploration of microorganisms such as bacteria and fungi this decade increases significantly to studied and developed because it is potentiality. However, fungi have more potential than bacteria because fungi produce ligninolytic extracellular enzymes such as lignin peroxidase, manganese peroxidase and laccase which play an important role in the degradation process of organic compounds such as dyestuff waste. This study will examine the potential of Pleurotuscystidiosus fungi in degrading textile dyes direct congo red (DCR) using different growing media. The stages include the ratio of fungi to growing media and the concentration of dyes that can be degraded at variations in dye concentrations of 150 mg−1 ppm, 200 mg L−1, 250 mg L−1, and 300 mg L−1. The results showed a ratio of 3% (b/b) in rice husk media with a degraded DCR concentration of 269 mg L−1 and 9% (b/b) in sawdust media with a degraded DCR concentration of 298 mg L−1. The result shows that sawdust media is better in degrading DCR with degradation efficiency of 94%.

Lead collection after automatic components removal from printed circuit boards as a “novel” process for noble metals recovery from WEEE
Authors: Bonelli Maria Grazia , Ferrini Mauro , Manni Andrea 
Published: June 2019

Abstract
In recent years, the recovery of noble metals from WEEE (Waste Electrical and Electronics Equipment) has received great attention in the academic and industrial community since it highly contributes to decrease the cost of the recycling and/or disposing of the short life cycle of electronic devices. Noble metals are mainly present in Printed Circuit Boards (PCBs) which are normally sold in bulk to specialized companies or sent to “recycling sites” where they may be open burned creating a great environmental concern. An alternate route is to further subject the PCB to a manual or automatic dismantling of the integrated circuits and chips. After a study conducted on more than 20.000 kg of WEEE, it has been shown that easily removable parts will account for 13,01% of the PCB w/w (0,75% of the whole sample) but will contain 89,50% of gold (2109 ppm). Since the removed parts are low in weight but highly enriched, lead collection could become a viable process for noble metal recovery. The main components of the above parts are the Silicon wafers. Since no bibliographic information is available on this kind of “gold matrix” the aim of the present study has been to assess the best quantity of the flux primary components (litharge, sodium bicarbonate, anhydrous borax) to enhance gold recovery. Results greater than 90% have been assessed.

Published: June 2019

Abstract
Residual soils are produced from weathering of rocks and commonly found in tropical humid areas. The geotechnical properties of residual soils are a function of the parent rock, the degree of weathering, and climate which vary from region to region. A thorough quantification of the geotechnical characteristics of residual soils is required for a safe and economic structure design. This study attempts to summarize a series of important geotechnical properties of a Malaysian granitic residual soil grade V which determine the suitability and ability of the soil for construction including particles size distribution, specific gravity, plastic index, soil water characteristic curve, and shear strength. The findings were compared with geotechnical properties of other residual soils which were reported previously. The results showed weathering grade and the percentage of fine particles are the two important factors in controlling the geotechnical properties of residual soils.

The results have been found that the strain energy density dissipation mechanism meaningfully effects on concrete foundation stress mechanism production and it leads to produce seismic differential settlement mechanism for concrete footing.
Mathematical model of fuel heat ignition considering space - time nonlocality
Authors: Eremin A V , Kudinov V A , Kudinov I V , Zhukov V V , Trubitsyn K V 
Published: June 2019

Abstract
Using the formula of the Fourier law, which takes into account the relaxation of the heat flux and the temperature gradient, a mathematical model of thermal ignition for systems with an exothermic internal source of heat was developed, taking into account the space-time nonlocality of the heat exchange process. Studies of boundary conditions of the first and third kind showed that taking into account the local nonequilibrium leads to an increase in the delay time of thermal ignition, irrespective of the conditions of heat exchange with the environment. It is shown that if the relaxation properties of materials are taken into account, the boundary conditions (of the first, second, or third kind) cannot be taken instantly, but only in a certain range of initial time. Consequently, the amount of heat supplied to the system has a certain limit, depending on its relaxation properties. Therefore, it is possible to conclude that there is also a limit on the value of heat transfer coefficients, which cannot be exceeded under any conditions of heat exchange with the environment.

Published: June 2019

Abstract
The aim of the work is to assess the energy-saving effect after the installation of automated individual heat points that carry out weather regulation of the heating load. The analysis was carried out for 18 educational institutions of the Belgorod region, in which energy service contracts were implemented in 2016. The data of the actual monthly consumption of heat energy during the basic heating season before the implementation of energy-saving measures and data of daily accounting of heat consumption during the two heating seasons after the installation of automated individual heat points were used. The average unit savings for all institutions was 14 per cent. It is established that the greatest value of economy, 20-30%, provides decrease in temperature in buildings to optimum level. Elimination of “overflows” in the autumn-spring period allows to save 5-10% of thermal energy. The decrease in temperature on non-working days is characterized by a small amount of savings, not more than 3%, or its absence.

Authors: Derevyanov M Yu , Pleshivtseva Yu E , Kordyukova L S , Rapoport A V 
Published: June 2019

Abstract
The paper discusses the approach for multi-criteria estimation of the efficiency of energy saving projects by the Data Envelopment Analysis (DEA) method. The measurement of efficiency of considered projects and the identification of sources of their inefficiency is a very important condition to put the projects into practice in industrial competitive environment. The term “energy saving project” refers to a project resulting in certain output improvements with respect to energy consumption of the technological process by spending certain inputs. Thus, the energy saving project can be treated as a production unit or Decision Making Unit (DMU). The estimation of the efficiency of energy-saving projects by DEA is illustrated here via example of an industrial enterprise for the production of cellular autoclaved aerated concrete. The nine typical inputs/outputs are used and the twelve DEA models are developed that characterize the technological, environmental, economic and comprehensive estimators of the efficiency of energy saving projects. The developed approach for multi-criteria estimation of the efficiency of energy saving projects by the DEA method has the potential of widespread use in practice for making effective management decisions on the formation of investment programs for industrial enterprises.

Authors: Romanov D O , Yavorovsky Y V , Smirnov V V 
Published: June 2019

Abstract
Electricity consumption represents high share of operational costs in district heating (DH) systems. Recent attempts of decreasing these costs have led to appearing the idea of systems with distributed variable speed pumps (DVSP). One of the parts of such systems is thermohydraulic dispatcher (THD). This article is concerned with application of THD for DH systems. Existing DH systems with low available hydraulic head are suitable for installing THD instead of booster pumps. Electricity consumption and cost of equipment for several schemes of heat substation are estimated. Application for low temperature district heating (LTDH) systems is considered. Further ideas of development DVSP systems are proposed. Schemes of cascade systems based on THD and hydraulic profiles are presented. In result, cascade systems can reach highest possible electricity saving effect due to eliminating of throttle valves at heat source, heat substations and heat consumers.
