Work of art in the space of network culture: Creativity as bricolage

The development of modern informational-communication technologies has led to the occurrence of the new unique sociocultural phenomenon – a network culture, with irony as the dominating rhetoric. In the space of network culture, under digital technologies, the forms, types, and functions of art, and creativity in general, change. The paper states that communication becomes the main function of art, while a work of art more and more becomes an object of communication. The authors propose to broaden the volume of creativity conception, going beyond the classical interpretation towards a broader understanding of this phenomenon, namely, creativity as bricolage. The methodological basis of the bricolage model of creativity, relevant for the new media art, is the concept of “bricolage” developed by Claude Lévi-Strauss. © 2020 The Author(s).

By the 2019 data, the film Matilda became the most unprofitable film supported by the Cinema Foundation of Russia: “Matilda’s losses became a sort of a record – 550 million rubles” (Zhitkova, 2018)

Dietary Quality and Comorbidities of Adults at Medical Risk for Diabetes

Background and aims: The current study evaluates following a special diet with diet quality and comorbidities (hypertension, hypercholesterolemia, and obesity) in four racial/ethnic groups diagnosed with prediabetes or “at risk for diabetes”. Methods and results: This is a cross-sectional analysis of data from the National Health and Nutrition Examination Surveys (NHANES), 2007- 2008 and 2009-2010. Sample weights were used to achieve a representative sample. Data were available for N = 2666 adults, aged ≥20 years (508 Mexican American, 294, Other Hispanic, 616 Black non-Hispanic, and 1248 White non-Hispanic) who were medically diagnosed with either prediabetes or “at risk for diabetes”. Those reporting following a special diet had greater odds of meeting saturated fat guidelines

Прогнозирование динамических характеристик термопар с тонкопроволочными чувствительными элементами

Thermocouples dynamic characteristicsʼ prediction is one of the relevant directions in the field of dynamic measurements of non-stationary temperatures of liquid and gaseous media. Thermocouples dynamic characteristicsʼ prediction makes it possible to provide effective continuous correction in automatic control systems for non-stationary temperatures. The purpose of this paper was to develop a theoretically justified relation linking the current or expected time constant of fine-wire thermocouples with the known time constant established at known parameters of liquid and gaseous media.A formula linking the time constant of fine-wire thermocouples with the conditions of heat exchange with the measured medium and the thermophysical characteristics of the thermocouple sensing elements has been deducted. An approximate formula is also given for calculating the internal resistance of wire sensing elements of thermocouples, which must be considered when calculating the time constant of a thermocouple. In consideration of the obtained formulas, a multi-parameter relation linking the current or expected time constant of fine-wire thermocouples with the known time constant set at the known parameters of the measured media has been formed.It is suggested to simplify the formed multi-parameter relation and make it dependent, for example, on the “expected velocity of the measured medium × expected density of the measured medium” complex (Vm2 ρm2 ). Simplified relations in the form of hyperbolic functions with constant parameters and argument in the form of Vm2 ρm2 complex were obtained for airflowat different temperatures, pressures, and velocities.On the example of airflow, it is shown that the complex multi-parametric relation linking the expectedand known time constants of thermocouples can be simplified to a hyperbolic dependence, where the argument can be the Vm2 ρm2 complex. Moreover, the degree of approximation of hyperbolic dependencies to the exact values of the multi-parametric relation can reach the R-square = 0.9592 criterion.A multi-parametric relation has been proposed. That relates the known time constant of a thermocouple to the expected or current time constant of the same thermocouple at other parameters of the measured medium from the point of view of the heat exchange and thermal conduction theory. The proposed relation can be used in automatic control systems of non-stationary temperature of various liquid or gaseous media to provide continuous correction of thermocouples dynamic characteristics. Depending on the number of measured medium parameters, the suggested multi-parameter relation can be replaced by simplified relations with other complexes containing, for example, density, velocity, flow rate and pressure of the measured medium.Прогнозирование динамических характеристик термопар является одним из актуальных направлений в области динамических измерений нестационарных температур жидких и газообразных сред. Прогнозирование динамических характеристик термопар позволяет обеспечить эффективную непрерывную коррекцию в системах автоматического управления нестационарной температурой. Целью данной работы являлась разработка теоретически обоснованного соотношения, связывающего текущую или ожидаемую постоянную времени тонкопроволочных термопар, с известной постоянной времени, установленной при известных параметрах жидких и газообразных сред.Выведено выражение, связывающее постоянную времени тонкопроволочных термопар с условиями теплообмена с измеряемой средой и теплофизическими характеристиками чувствительных элементов термопар. Получена также приближённая формула для расчёта внутреннего сопротивления проволочных чувствительных элементов термопар, которое необходимо учитывать при вычислении постоянной времени термопары. С учётом полученных выражений сформировано многопараметрическое соотношение, связывающее текущую или ожидаемую постоянную времени тонкопроволочных термопар, с известной постоянной времени, установленной при известных параметрах измеряемых сред.Сформированное многопараметрическое соотношение предложено упростить и сделать зависимым, например, от комплекса «ожидаемая скорость измеряемой среды × ожидаемая плотность измеряемой среды» (Vm2 ρm2 ). Для воздушного потока при различных температурах, давлении и скорости получены упрощённые соотношения в виде гиперболических функций с постоянными параметрами и аргументом в форме комплекса Vm2 ρm2.На примере воздушного потока показано, что сложное многопараметрическое соотношение,связывающее ожидаемую и известную постоянные времени термопар, можно упростить до гиперболической зависимости, где аргументом может выступить комплекс Vm2 ρm2. Причём степень приближения гиперболических зависимостей к точным значениям многопараметрического соотношения может достигать по критерию R-square = 0.9592.Предложено точное с точки зрения теории теплообмена и теплопроводности многопараметрическое соотношение, связывающее известную постоянную времени термопары с ожидаемой или текущей постоянной времени этой же термопары при иных параметрах измеряемой среды. Предложенное соотношение может быть использовано в системах автоматического управления нестационарной температурой различных жидких или газообразных сред для обеспечения непрерывной коррекции динамических характеристик термопар. В зависимости от числа измеряемых параметров среды предложенное многопараметрическое соотношение может быть заменено упрощёнными измеряемой соотношениями с другими комплексами, содержащими, например, плотность, скорость, расход и давление среды
