    The materials presented the possibilities development of intellectual property complex innovation projects modern highly effective science-based problems of improving the use of wastes of different industries on a complex enterprise that can provide all its energy needs alone. Some features of the possibilities of solving evidence-based problems of development of mechanisms for identifying syner-gistic processes, their scientific justification improving the use of wastes of different industries on a complex enterprise. The problem of wastes utilization and recycling is present as complex synergetic processes research and analysis of energy- and resource saving process-es for treatment of polymer wastes of various origin. The research focused on the study of issues such as the development of models of waste-modifying polymer. The investigation are focused in researching such problems as selection of scientific based methods of wastes to be utilized or recycled; the development of appropriated process flow sheets and choice of modifications additives and equipment for polymers waste recycling. The choice of appropriate plants with selected energy resources is very important for projects realization

    Resource Competition May Lead to Effective Treatment of Antibiotic Resistant Infections

    Drug resistance is a common problem in the fight against infectious diseases. Recent studies have shown conditions (which we call antiR) that select against resistant strains. However, no specific drug administration strategies based on this property exist yet. Here, we mathematically compare growth of resistant versus sensitive strains under different treatments (no drugs, antibiotic, and antiR), and show how a precisely timed combination of treatments may help defeat resistant strains. Our analysis is based on a previously developed model of infection and immunity in which a costly plasmid confers antibiotic resistance. As expected, antibiotic treatment increases the frequency of the resistant strain, while the plasmid cost causes a reduction of resistance in the absence of antibiotic selection. Our analysis suggests that this reduction occurs under competition for limited resources. Based on this model, we estimate treatment schedules that would lead to a complete elimination of both sensitive and resistant strains. In particular, we derive an analytical expression for the rate of resistance loss, and hence for the time necessary to turn a resistant infection into sensitive (tclear). This time depends on the experimentally measurable rates of pathogen division, growth and plasmid loss. Finally, we estimated tclear for a specific case, using available empirical data, and found that resistance may be lost up to 15 times faster under antiR treatment when compared to a no treatment regime. This strategy may be particularly suitable to treat chronic infection. Finally, our analysis suggests that accounting explicitly for a resistance-decaying rate may drastically change predicted outcomes in host-population models

    Розглянуті методи та засоби контролю фарфорових ізоляторів на наявність дефекту типу відкрита мікроскопічна пористість. Показано, що відкрита мікроскопічна пористість є найбільш небезпечним дефектом виробничого походження і є причиною більше 80% відмов фарфорових опорних стержневих ізоляторів. В результаті аналітичних досліджень виділено ультразвуковий метод неруйнівного контролю як найбільш придатний в умовах експлуатації фарфорових ізоляторів. Показані шляхи вдосконалення методики проведення ультразвукового контролю для підвищення його достовірності.Examined the methods and devices of control of porcelain insulators for presence of defects such as open microscopic porosity. It is shown that open microscopic porosity is the most dangerous defect production origin and is responsible for over 80% of failures of porcelain support insulators. Considered methods of control are divided into two groups: destructive and non-destructive. For each method are highlighted their advantages and disadvantages. The analysis showed that most of the existing methods are destructive and require considerable time to implement them. As a result of analytical studies highlighted ultrasonic NDT method as the most suitable in conditions of porcelain insulators. Ultrasonic method has a good correlation between the results of the measured values of the velocity of ultrasound in porcelain insulators with the presence of open microscopic porosity. However, found that the methods of ultrasonic testing of porcelain insulators is rather complicated, unproductive and can cause the appearance of a large subjective error. Therefore shown the ways to improve methods of ultrasonic testing of insulators to improve its reliability.Рассмотрены методы и средства контроля фарфоровых изоляторов на наличие дефекта типа открытая микроскопическая пористость. Показано, что открытая микроскопическая пористость является наиболее опасным дефектом производственного происхождения и является причиной более 80% отказов фарфоровых опорных стержневых изоляторов. Рассмотренные методы контроля разделены на две группы: разрушающие и неразрушающие. В результате аналитических исследований выделен ультразвуковой метод неразрушающего контроля как наиболее подходящий в условиях эксплуатации фарфоровых изоляторов. Показаны пути совершенствования методики проведения ультразвукового контроля изоляторов для повышения его достоверности
