    Nowadays, at all levels of created automated control systems for technological processes, programmable technical means are used that require specific software within framework of necessary functional tasks. This software should include a set of software tools that communicate with technical devices and organize «human-machine interface» (HMI) in the form of application software for AWPs with assigned communication tasks for persons, responsible for management decision-making: operators, dispatchers, managers. However, hardware architecture is unique for each particular case, so it is necessary to refine or create a new control system. This is a rather laborious process. To simplify creation of such systems SCADA-systems are used. Article is devoted to development of SCADA-component for trunk gas pipeline's compressor workshop. Developed component allows tracking the characteristics of gas transportation process selected by operator. Development is based on «Windows» operating system and integrated environment TRACE MODE (SCADA/HMI)

    The objective: To develop a method for predicting exacerbation of chronic illness in children with asthma and cystic fibrosis, patients with influenza, based on the study of the dynamics of cytokines. Materials and methods: Were examined 52 patients with bronchial asthma and 45 children with cystic fibrosis at the age from 1 year to 12 years, located in infectious pulmonary Department at the planned treatment of underlying pathology, in which influenza was in-hospital infection. Control group observations included 40 patients with the flu, without concomitant pulmonary disease. The etiology of viral infection was established by detection of viral RNA in nasopharyngeal swabs by PCR. Among the influenza viruses were identified influenza АH1N1, АH3N2, influenza B, and in 2009–2010 the predominant antigen was the pandemic influenza virus АH1N1pdm09. Determination of the concentration of serum interleukins IL-1β, IL-4, IL-8, IL-10, ТNF-α, IFN-γ was performed in the 1st and 3rd day of hospitalization cytokines by the solid-phase immune-enzyme assay. Analysis of the results performed using statistical package SPSS 17.0 EN for Windows. Results: The flu caused the aggravation associated bronchopulmonary pathology in 2/3 of children, as MV patients, and patients with BA (65,4%-66,7%, respectively). With an increase of the ratio of IL-4 / IFN-γ and IL-10/IFN-γ, at least 5-6 times, influenza can be considered a trigger of exacerbation of chronic bronchopulmonary pathologies that require amplification of the therapy of bronchial asthma and of сystic fibrosis. The growth of prognostic coefficients in 2-3 times allows using for treatment of influenza in these patients only antiviral agents. Conclusion: The study has shown a method for predicting exacerbation of bronchial asthma and cystic fibrosis in children at an early stage of influenza by calculating the ratio of IL-4/IFN-γ and IL-10/IFN-γ in children aged from 1 year to 12 years

Контрольную группу наблюдений составили 40 пациентов с гриппом, но без сопутствующих бронхолегочных заболеваний. Этиология вирусной инфекции устанавливалась определением вирус-специфической РНК в носоглоточных смывах методом ПЦР. Среди вирусов гриппа определялись АH1N1, АH3N2, В, а в 2009–2010 гг. преобладающим антигеном являлся вирус пандемического гриппа АH1N1pdm09. Определение содержания в сыворотке крови интерлейкинов IL-1β, IL-4, IL-8, IL-10, ТNF-α, IFN-γ проводилось в 1-й и 3-й день госпитализации «сэндвич»-методом твердофазного иммуноферментного анализа. Статистическая обработка результатов выполнена с применением программы SPSS 17.0 RU for Windows. Результаты: грипп вызывал обострение сопутствующей бронхолегочной патологии у большинства детей, больных как муковисцидозом, так и бронхиальной астмой (65,4% и 66,7% соответственно). При увеличении коэффициента соотношения IL-4/IFN-γ и IL-10/IFN-γ как минимум в 5–6 раз грипп может считаться триггером обострения сопутствующей хронической бронхолегочной патологии. Нарастание прогностических коэффициентов в 2–3 раза позволяет ограничить лечение гриппа у данной категории больных противовирусными средствами. Заключение: представлен способ прогнозирования обострения бронхиальной астмы и муковисцидоза у детей на ранней стадии гриппа с помощью расчета коэффициентов соотношения IL-4/IFN-γ и IL-10/IFN-γ у детей в возрасте от 1 года до 12 лет.

    The article presents an overview of the current state of work on the integrated use of hydrocarbon raw materials for energy supply to industrial and domestic consumers, as well as generation of process gas. A thermal scheme of an energy-chemical plant with a combined production of energy carriers (thermal and electric energy) and a process gas containing H2 and CO is proposed. The software product was registered in the form of a mathematical model of a partial oxidation reactor, which made it possible to estimate the parameters of gas synthesis at an air flow coefficient of α=0,7, a pressure increase of πk=5, and a specific steam flow rate of 6,5 kg/kg (N2=35,8 %, H2O=50,2%, CO2=5,9%, CO=2,6%, H2=5,5% and temperature 1570 °C), as well as geometrical dimensions of the apparatus D=1,3 m and L=10,8 m

    The integration of energy storage into energy systems is widely recognised as one of the key technologies for achieving a more sustainable energy system. The capability of storing energy can support grid stability, optimise the operating conditions of energy systems, unlock the exploitation of high shares of renewable energies, reduce the overall emissions and, consequently, limit the environmental impacts of energy production, transformation and consumption. Energy storage is a very wide and variegate topic in which several aspects \u2013 from material and process design, control and optimisation, economic and environmental aspects, specific application, etc. \u2013 play a fundamental role. The present paper offers a critical overview of the main energy storage to help readers navigate across the different technologies available to store energy, their current development status, common applications and future research trends and opportunities. Due to the complexity of the topic, the paper focuses the attention on thermal and electrochemical energy storage and their synergies with the development of renewable energy source technologies
