Diverse community energy futures in Saskatchewan, Canada

Abstract: This research explores peoples’ place attachment and context surrounding power production and energy futures. Facilitated, deliberative focus groups were conducted as comparative case studies in three fossil fuel-dependent cities in Saskatchewan Canada: Estevan (situated next to the provincial centers of coal, oil and gas production), Saskatoon (situated more northerly and furthest from coal, oil and gas production) and the capital city of Regina. (situated between the other two communities). This study supports the conclusions: (1) participants believed the focus groups improved their knowledge surrounding power production; (2) although there is strong support for wind and solar power production, there is a gap in implementation; and (3) place-based location impacts perceptions of power production sources. Participants were surveyed before and after focus group meetings to explore the perceptions and preferences of power productions sources. All three communities favored renewables in the order of solar and wind. Estevan, supported carbon capture and sequestration (CCS) to a greater degree and perceived much lower risk surrounding CCS than the other two communities. This may be explained by information gaps in this community. Participants were far less likely to believe a climate crisis is occurring, and while recognizing health concerns surrounding coal, they spent considerably more time discussing the loss of coal and its impact on their economy. Saskatoon, the community furthest from coal oil and gas production, spent considerable time discussing renewables, and when asked about coal, oil and gas identified the need to transition and retrain dependent workers. Although the uranium sector is present in Saskatchewan and in closer proximity to Saskatoon, there was little knowledge or support for new small modular nuclear reactors.

THE MODELING OF ECONOMIC EFFICIENCY OF PRODUCTS CARRIAGE-BUILDING PLANT IN CONDITIONS OF DYNAMIC PRICING

Purpose. The purpose of the work is modeling of economic efficiency of products manufactured by carriage-building plant in conditions of dynamic pricing for different levels to engineering industry controls. Methodology. Economic feasibility of engineering production estimate for economic performance indicators and efficiency is profitability. Profit is economic results, showing the absolute result of the activity of engineering production, excluding used resource. To determine the cost-effectiveness should be applied relative index – profitability, which characterizes the amount of profit received from each monetary unit invested in production. Findings. Indicator of the general level of profitability indicates the general production efficiency of the company and is determined by the ratio of the balance sheet profit to the amount of value of fixed assets and revolving funds. This figure shows how effectively the material resources of the enterprise, thus characterizing the efficiency of investing in the production of the monetary unit. In the context of dynamic pricing was simulated indicator of economic efficiency of products manufactured by carriage-building plant. In addition, this model allows doing the operational control of the economic efficiency of the engineering industry at a variety of price changes on the world market.

MATHEMATICAL MODELING OF THE FOREST FIRE IMPACT ON THE BRANCH OF A CONIFEROUS TREE

It is necessary to develop quantitative methods to assess the formation of thermal burns in the morphological parts of coniferous trees. The purpose of the study can be formulated as follows: mathematical modeling of heat transfer in the layered structure of a coniferous tree branch under the influence of a forest fire front. The heat propagation in the “branch-needles-flame zone” system is described by a system of non-stationary differential equations of heat conduction with the corresponding initial and boundary conditions. As an object of research, a digital model of a branch of a coniferous tree for various species, namely, pine, larch and fir, was used. Temperature distributions are obtained for different variants of the branch structure and conditions of the impact of the forest fire front. Conclusions are made about the need for further modernization of the mathematical model. The developed model is the basis for creating software tools for specialized geographic information systems.</jats:p

THE EFFECT OF DEPOSITED HERBICIDAL PREPARATIONS ON GRAIN CROPS

The aim of the study was to study the effectiveness of deposited herbicidal preparations metribuzin and tribenuron-methyl based on biodegradable poly-3-hydroxybutyrate in micro-field crops of grain crops (spring wheat variety "Novosibirskaya 15" (Triticum aestivum) and spring barley variety "Biom" (Hordeum vulgare). The research was carried out in the growing season of 2019 in a field station of the Krasnoyarsk State Agricultural University, located in the vicinity of Krasnoyarsk on meadow-chernozem thick heavy loamy soil. As a result of the study, it was shown that the introduction of deposited herbicidal preparations contributed to a better control of the number of weeds in comparison with their free forms, which contributed to a greater formation of productive stems and, as a consequence, an increase in crop yields. The maximum decrease in the number of weeds was recorded with the introduction of MET preparations, where the number of weeds on August 20 decreased by more than 70% (20 pcs / m2) in comparison with the negative control. Similar effects of herbicides in free and deposited form are shown in crops of spring barley varieties "Biom". The herbicidal effect of TRIB and MET deposited in a matrix of P (3GB) mixed with sawdust was more pronounced compared to spraying with free forms of pesticides. The results of the study showed that the use of experimental forms with TRIB increased the biological yield of grain crops by improving the indicators of the yield structure and effective control of weeds. The maximum number of productive stems was recorded on spring barley with the addition of deposited tribenuron-methyl (712 pcs / m2), where the highest yield was formed (6.12 t / ha).</jats:p
