This paper presents the results of calculations to reduce greenhouse gas emissions in agricultural sectors of the Republic of Uzbekistan within the framework of the project: “Sustainable Agriculture Development and Climate Change Mitigation”. The initial data were the characteristics of the implemented installations based on renewable energy sources for the period of 2014-2018. Most of these installations were biogas settings based on the principle of anaerobic fermentation, as well as solar water heating and photovoltaic stations. The calculations were performed according to the “AMS-III.D” and “AMS-I.J” methods by the “Global Environmental Fund” experts. The developed computer programs were applied to calculate the arrival of radiation and the duration of sunshine during the year on the territory of Uzbekistan. According to the calculations, the reduction of greenhouse gas emissions was 1338840.5 tons of CO2 for the indicated period during the operation of installations based on renewable energy sources. Within the framework of this project, the total potential of generating electric energy from biogas settings and solar photovoltaic stations at the amount of 10,424 MWh was estimated.
BPRS displacement and its characteristics showed that the possible causes of deviations are imperfections of the method, operating principle, manufacturing inaccuracy, the volatility voltage amplitude of the power source, its form, and frequency, as well as other adverse external conditions.
The most important characteristic of biparametric resonance sensors (BPRS) of displacement, like any measuring transducer, is its deviation [1].
In this work, the deviation of the BPRS movement was estimated by the method of parametric structural schemes (PSS) [3]. The advantage of this method is the ability to analyze deviation that is invariant from the physical nature of the phenomena occurring within the sensors. Besides, this method is visual and convenient when compiling deviation equations that take into account all their types.
The PSS of the developed BPRS displacement taking into account possible sources of deviations is shown in Figure 1.
In view of the systematic and random component of the deviation of each elementary transformation according to PSS, it is allowed to write the following system of equations for the right section of the BPRS:
This article provides definitions of the positive and negative effects of the use of chlorine and ozone in water disinfection and presents the methodology and results of experimental studies of the parameters of water treatment with ozone, the electrodispersion method, as well as the electrode system “potential plane with corona needles - grounded plane”. The parameters of water treatment modes were determined by the method of three variants of aerosol charge, negative, positive and bipolar. The parameters of water treatment with ozone determined on the basis of these studies were verified on the basis of experimental studies of the process of ozone effects on aerosol particles in the contact chamber. The methodology and analysis of the results of these studies are given. Based on these studies, the best ratios of the parameters of water flow, air velocity and electrical voltage were determined. The best disinfection result was determined by the charge polarities of the water aerosol.
This paper highlights the methods of resenting mode in the transudation with distributed parameters. The transient parameters of the power supply were analyzed. It was discovered that resonance is provided in a small range of movement of the moving component of the sensor in known turbofan engines, indicating that the known techniques of sustaining the resonance mode are flawed. Further study should focus on developing novel methods for preserving resonance mode over the entire range of change of the converted value, general principles of turbojet engine construction, and a complete examination of their resonant circuits, according to the findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
