Comparative analysis of the DNA isolated from thyme leaves using different methods
Background. The base for a molecular analysis is DNA of high quality. For DNA isolation, different kits or classical methods are used. For mass analysis, isolation with kits is a very expensive process. So, the objective of our investigation was to find a cheap method for high-quality DNA isolation from leaves of various thyme cultivars.Materials and methods. Leaves cut from thyme accessions (Thymus mastichina L. cv. ‘Svetliachok’, T. striatus Vahl. cv. ‘Jubileiniy’, T. vulgaris L. cv. ‘Fantasia’, and T. vulgaris cv. ‘Jalos’.) maintained ex situ in the collection of the Nikita Botanical Gardens were used as the material for the analysis. Light microscopy was used to study leaf anatomy and localize essential oil on leaf cross sections. Essential oil was extracted on Ginsberg devices, and phenolic content was measured with The Folin–Ciocâlteu reagent (FCR). Commercial kits (DiamondDNATM, PureLink® Plant Total DNA Purification Kit) and classical methods (CTAB, CTAB with 2% polyvinylpyrrolidone) were used for DNA isolation. DNA quality was evaluated spectrophotometrically, with electrophoresis (horizontal, automated system Agilent 4200 TapeStation) and PCR.Results. The analysis showed that the leaf blade mesophyll of four thyme cultivars had inclusions with essential oil. The content of essential oil and phenolic compounds was measured biochemically. Since the plants were characterized by the presence of secondary metabolites, DNA was isolated by different methods. Spectrophotometry demonstrated that the classical CTAB method and CTAB with 2% PVP provided the best results. Using an automated electrophoresis system, the presence of high-molecularweight DNA (more than 52000 bp) in significant amounts was detected in the samples isolated with DiamondDNATM kit and CTAB + 2% PVP.Conclusion. Among the tested kits and methods, CTAB + 2% PVP provided thyme DNA suitable for PCR and, presumably, for genome library preparation. The low cost of reagents for this technique makes it applicable for future mass analysis of plant material
Адаптивная информационно-управляющая система динамического мониторинга фактической обводненности авиатоплива в технологических процессах авиатопливообеспечения
Modern domestic and international standards, regulators of the aviation fuel industry, considering the negative impact of the presence of mechanical impurities and water in aviation fuel on the performance and life cycle of aircraft engines, fuel metering equipment, fuel systems of aircraft (A/C), as a threat factor for flight safety, impose high requirements for the purity of aviation fuel while operating aeronautical equipment. At the same time, the causes and sources of water content in jet fuel are a source of economic losses, the most important criterion for the success of the Aerodrome Fueling Complex business. The article considers the task of developing reliable and automated methods as well as technologies for controlling these contaminants, for example for determining water content in aviation fuel when refueling aircraft, and the necessity to minimize an effect of a human factor. The automation of aviation fuel quality monitoring processes, the transition from discrete control methods to continuous ones, from static control methods to dynamic ones (in-line), from indirect methods to direct ones are becoming relevant. The possibilities of end-to-end accounting and analysis of aviation fuel purity parameters at all stages of the aviation fuel life cycle are shown. The article considers the methods and conducts the analysis of known techniques and devices used to determine, measure and indicate actual water content, presence of dissolved, free and total water in jet fuel. The technical solution of continuous automated control of the actual water content level of the jet fuel flow in the processes of aviation fuel supply and aircraft refueling in an information system that provides on-line monitoring and dynamic measurement of the quantitative content of dissolved and free water in the jet fuel flow, is presented. The technical solution for the continuous determination of the quantitative water content in the jet fuel stream is proposed. At the same time, the solution of the problem of monitoring water content in jet fuel is combined with the technological process to control the purification of jet fuel from water. The paper represents an adaptive information management system for continuous monitoring of the water content level of the jet fuel flow, which will allow specialist to substantially increase a level of automatization of aircraft aviation fuel supply technological processes, decrease a negative impact of a human factor, increase economic effectiveness of the aviation fuel supply complex. The system is designed to carry out continuous, automated control (monitoring) of water content in the jet fuel flow at all the stages of the jet fuel movement: receiving, storing and delivering jet fuel and refueling aircraft, in particular fuel and lubricants warehouses (fuel and lubricants), refueling complexes and pre-apron filling points. It can also be used in the fuel system of the aircraft, as a system to prevent water content in the jet fuel. The integration of automation tools will enable us to improve the quality of management of aviation fuel supply and aircraft refueling to ensure timely operational decision based on real data in real time mode, provided the proposed system integration into the airport system for operational data exchange.Современные отечественные и международные требования регуляторов отрасли авиатопливообеспечения, принимая во внимание негативное влияние присутствия механических примесей и воды в авиатопливе на работоспособность и ресурс авиадвигателей, топливорегулирующей аппаратуры, топливных систем воздушных судов (ВС) как фактора угрозы безопасности полетов ВС, предъявляют к чистоте применяемого при эксплуатации авиационной техники авиатоплива высокие требования.

DEVICE FOR CONTINUOUS MONITORING OF AVIATION FUEL PURITY IN THE TECHNOLOGICAL SCHEME OF AIRCRAFT FUEL SUPPLY
Currently, special attention is paid to the aircraft fuel quality as a component of safety to ensure trouble-free operation of the fuel system. The existing system of quality control involves periodic sampling of the fuel in the container and their subsequent control by the normalized quality indicators that do not identify possible reasons for the deterioration of these indicators to remove them for trouble-free operation and do not identify the factors of pollution sources. The monitoring system generally ensures the implementation of measures to preserve the quality of aviation fuel and flight safety of serviced civil aviation airlines at current level according to regulatory requirements. The article describes the mathematical model for calculation parameters of indicator filtering partitions based on cascade filtration theoretical studies of mechanical impurities. Pores of indicator filtering partitions calculated by means of mathematical model have been experimentally tested on simulator stand and showed a good convergence of calculated and experimental results. The use of cascade filtration of fuel with different indicator partitions parameters made it possible to develop a device for fuel purity monitoring, allowing continuous (inline) monitoring the level of liquid flow contamination at various points of technological equipment (for example, after the pump, at the inlet and outlet of tanks and units, the output of the filter, etc.) and to carry out functional diagnostics of units condition process equipment by monitoring changes of particle parameters and the wear occurrence
