Published: November 2019

Abstract
The existence of opportunities and prospects for scarce metals extraction from ash and slag waste of high-sulphur fuel oil burning was noted. The volatile ash produced during fuel combustion consisting mainly of metal oxides contains highly toxic substances. Their binding in a zone of burning of fuel is important not only for the purpose of extraction and further use in industry, but also to prevent their harmful environmental impact. It was shown that in the case of petroleum fuel oil an effective way to improve the performance of the fuel while maximizing the adverse environmental consequences of its combustion is to develop new generation effective fuel additives and improve filtration systems for flue gases. It has been established that the use of additives based on carbonate sludge makes it possible to achieve greater binding of metal oxides to non-volatile compounds in the burning zone of the fuel and their reduction in the composition of the emission gases. The mutual using of carbonate additives with the admixture of carbon nanotubes the effect may be even greater. Rational ash and slag waste utilization through the use of their beneficial properties will allow to free occupied areas and reduce environmental damage to the environment.

Abstract
Cultivation of duckweed Lemna minor in conditions of St. Petersburg was carried out. Two cultivation variants were studied: 1- in a natural reservoir of Petergof; 2 - in an artificial reservoir at the yard of Peter the Great St. Petersburg Polytechnic University (Russia) during a period from May to July 2017. The following cultivation conditions were determined: lighting, temperature. The population growth intensity was estimated by increase of plant cover area of the pond. The most favourable conditions appeared to be at natural pond in Petergof. Daylight features, lightning intensity of the Leningrad Region are less favourable than that for south Russian regions, so biomass production rate is drastically lower. However, the climatic characteristics (moderate climate, transient from continental to marine) allows increasing L. minor cultivation period: from May to November inclusive. We carried out atomic-physiological investigation of fronds in summer and autumn, as well as epidermis and chlorenchyma cell analysis, which allow one to characterize photosynthesys system of the plants.

Published: November 2019

Abstract
In the current work, thixoformedA356-5wt%TiB2in-situ composites were subjected to dry sliding wear. Further, the wear surface topography and wear debris was analyzed. The results show that wear rate is significantly influenced by redistribution of TiB2 particles in the matrix, refinement of fine globular α-Al grains and modification of eutectic Si. As expected, the thixoformed composites show better wear resistance than the alloy. Moreover TiB2 particles lower the coefficient of friction when reinforced in A356 alloy, in both gravity cast and thixoformed conditions. Also, it is interesting to note that there exist a linear relationship between wear rate and hardness of composites, irrespective of the processing history. The wear rate in the thixoformed composite is reduced by 48% as compared to gravity cast alloy. The improvement in wear resistance in the present thixoformed composite is not only due to the presence of fine TiB2 particles but also due to refinement of α-Al and eutectic Si caused due to the plastic deformation during thixoforming. In addition, high hardness and strength of thixoformed specimens compared with gravity cast parts has resulted in lower coefficient of friction in thixoformed A356-5TiB2 in-situ composite.

Abstract
The importance of renewable energy sources cannot be denied in the era of increase of greenhouse gas emission and depletion of fossil fuels. The wind energy and design of new yet effective windmills become a necessity nowadays. This paper introduces a new configuration of wind turbine with a horizontal axis and ANSYS-based dynamic analysis of its high-speed protection shield that protects the turbine from overspending at extreme wind conditions. In comparison to traditional horizontal wind turbine structure, HAWT blades have a flat shape, and they are exposed to wind stream in such a way that the wind forces are strictly perpendicular to the blade surfaces. This structure extracts more wind energy and minimizes the useless forces affecting shaft joints in traditional wind turbines. The ANSYS-based force analysis presented in this paper proves the advantage of using of protection shield in such windmill structure.
