Актуальность исследования обусловлена широким применением бумаги в различных сферах и необходимостью эффективного удаления влаги для поддержания состояния бумажной продукции. В данной работе рассматриваются традиционные способы сушки и акусто-конвективный, исследуемый в ИТПМ СО РАН, который проводится без теплового воздействия. На подготовительном этапе определялась начальная влажность образцов термо-вакуумным методом при 120°C, после чего они увлажнялись капиллярным способом до максимальной влажности около 200%. Сушка осуществлялась следующими способами: тепловая сушка в сушильном шкафу при 120°C в течение 25 минут, термо-конвективная сушка при 140°C за 7 минут, и акусто-конвективная сушка при частоте 120 Гц и интенсивности 160 дБ, температура потока равен 15°C, в течение 20 минут. Результаты показали, что термо-конвективная сушка наиболее эффективно снижает влажность листов бумаги до начального уровня всего за 5 минут. Акусто-конвективная сушка достигала того же результата за 15 минут, в то время как тепловой метод занимал 25 минут. Применение акусто-конвективной установки демонстрирует перспективы для ускорения процессов сушки, что может быть полезно для обработки различных пористых материалов в промышленном производстве.

This paper presents the results of research into the development of compositions based on VK-95-1 ceramic powder for DLP 3D printing. The dynamic viscosity of different compositions was investigated as a function of mixing methods, content and type of ceramic powder. The polymerisation parameters of ceramic suspensions were studied for compositions with 60 and 70 wt.% ceramic powder. The introduction of additional amount of photoinitiator was proposed to increase the curing depth of the obtained suspensions. The samples were prepared by DLP 3D printing method using different UV irradiance. According to the results of the conducted research, it was found that the introduction of dispersing additive in the initial powder allows to reduce the viscosity of the obtained suspensions up to 2.5 times. The maximum curing depth of compositions without additional content of photoinitiator with 60 and 70 wt.% of ceramic powder is 120 and 140 microns, respectively, with the addition of 0.5 wt.% of photoinitiator (based on photopolymer binder) the curing depth increases up to 340 microns. The microstructure of the printed specimens is represented by uniformly distributed in the polymer binder.

Нанотермит Bi2O3/Al в смеси с газогенерирующей добавкой азодикарбонамида (АДКА), рассматривалась нами, как перспективная система для создания гибридных нанокомпозиционных материалов. В работе приведены результаты исследования скорости горения и силы взрыва нанотермитной композиции Bi2O3/Al/АДКА, где помимо изменения концентрации АДКА в системе, мы видоизменяли принципы рецептурной компоновки композиции. Показано, что введение азодикарбонамида в нанотермит Bi2O3/Al, оказывает благоприятное влияние на взрывчатые параметры композиции, так удаётся достичь повышения силы взрыва на 29 %, а скорость горения в слое 0,1 мм на 170 м/с относительно базовой нанотермитной пары Bi2O3/Al. В целом, зависимость взрывчатых параметров от концентрации АДКА в композиции имеет экстремальный характер, где пиковые значения скорости горения и силы взрыва достигаются при содержании добавки в системе - 10 и 15 % (в зависимости от рецептурно компоновки), после увеличение концентрации АДКА уже оказывает негативное влияние на исследуемые параметры – при содержании азодикарбонамида ~30 %, взрывчатые параметры композиции снижаются до уровня базовой нанотермитной системы Bi2O3/Al.
We considered Bi2O3/Al nanothermite mixed with gas-generating azodicarbonamide (ADCA) additive as a perspective system for developing hybrid nanocomposite materials. In this work, we present the results of the research on the burning velocity and explosion force of the Bi2O3/Al/ADCA nanothermite composition, where in addition to changing the concentration of ADCA in the system, we modified the prescription configuration principles of the composition. It is shown that the addition of azodicarbonamide to Bi2O3/Al nanothermite has a beneficial effect on the explosive parameters of the composition, so it is possible to achieve an increase in the explosive force by 29%, and the burning velocity in a layer of 0.1 mm by 170 m/s relative to the basic Bi2O3/Al nanothermite pair. In general, the dependence of combustion performance on the concentration of ADCA in the composition has an extreme character, where the peak values of burning velocity and explosion force are reached at the content of the additive in the system - 10 and 15% (depending on the configuration), after increasing the concentration of ADCA already has a negative effect on the studied parameters - at the content of azodicarbonamide ~30%, the explosive parameters of the composition are reduced to the level of the basic nanothermite system Bi2O3/Al.

В настоящее время среди различных видов пылеуловителей наибольшее распространение получили аппараты инерционного типа, они применяются практически на всех производствах, в том числе в металлургии, машиностроении и химической промышленности. Эффективность работы таких аппаратов зависит от многих факторов, в том числе от физико-химического состава частиц и параметров пылегазового потока. Поэтому при разработке принципиально новых конструкций пылеуловителей и модернизации существующих аппаратов необходимо оценивать влияние параметров пылегазовой среды на эффективность пылеулавливания. В данной работе с помощью современных программных средств, реализуемых метод конечных элементов, исследовано влияние запыленности газа на структуру потока в новом инерционно-центробежном пылеуловителе. Получены картины распределения скоростей потока в различных сечениях аппарата. Установлено влияние начальной запыленности газа на картину распределения скоростей. Подтверждена возможность эксплуатации инерционно-центробежного пылеуловителя в условиях высоких значений концентрации частиц дисперсной фазы в газовом потоке.
At present, among various types of dust collectors, the most widely used are inertial type devices; they are used in almost all industries, including metallurgy, mechanical engineering and the chemical industry. However, such devices have a number of disadvantages, including low efficiency under conditions of high initial dustiness of the gas flow. Therefore, when developing fundamentally new designs of dust collectors and upgrading existing devices, it is necessary to evaluate the influence of the parameters of the dust and gas environment on the efficiency of dust collection. In this paper, using modern software tools implemented by the finite element method, the influence of gas dustiness on the flow structure in a new inertial-centrifugal dust collector was investigated. Flow velocity distribution patterns in different sections of the device were obtained.The influence of the initial dustiness of the gas on the velocity distribution pattern has been established. The possibility of operating an inertial-centrifugal dust collector under conditions of high concentrations of dispersed phase particles in the gas flow has been confirmed.

Published: January 2025

Purpose: The research addresses the limitations of the traditional force-based approach in earthquake-resistant design, particularly its inability to account for inelastic behaviour fully. It explores the potential of nonlinear static assessment techniques within the performance-based seismic design (PBSD) framework to provide a more accurate measure of earthquake structural performance.
Design/Methodology/Approach: This research develops a set of damage indices to quantify structural damage in moment-resisting frames (MRFs) based on engineering demand parameters obtained through nonlinear analysis. The study examines reinforced concrete (R.C.) structures of various heights, evaluating their seismic load-bearing capacity and resilience using the PBSD approach.
Findings: The proposed damage indices offer a reasonable way to quantify structural damage and enhance the understanding of the plastic collapse process. Performance-based design mainly benefits R.C. structures, improving their seismic resilience and cost-effectiveness.
Research Limitation: Accurately quantifying building damage remains challenging even with nonlinear assessment tools. Further work is required to refine these tools for more precise damage quantification in various building types.
Practical Implication: The findings have practical implications in reducing repair costs and ensuring public safety by providing preliminary damage estimates for tall buildings. The PBSD approach also meets acceptance criteria for immediate occupancy and life safety across various seismic intensities.
Social Implication: By enhancing buildings' resilience to earthquakes, this research contributes to safer urban environments, reducing potential fatalities, economic losses, and downtime associated with earthquake-induced damage.
Originality/Value: This study provides valuable insights into performance-based seismic design and presents a practical method for quantifying structural damage in R.C. structures. The proposed damage indices and PBSD approach significantly advance the safety and cost-effectiveness of earthquake-resistant buildings.

ABSTRACT
Aerial applications of pesticides for adult mosquito control have emerged as effective tools in integrated mosquito management due to wider reach compared with ground-based methods. A key determinant for efficacy is the swath or line of spray deposition. This study aimed to assess the potential of aerial buffer sprays, which specifically target mosquito habitats, in comparison to traditional full-area aerial and ground-based applications. The efficacy and cost implications of these methods were evaluated in hot spot areas of St. Johns County, FL. Mosquito populations in 4 areas, 2 for buffer aerial (St. Johns County Golf Course and World Golf Village), 1 for full aerial (Flagler Estate), and 1 for ground-based (Elkton) treatments, were assessed using the Centers for Disease Control and Prevention light traps baited with octenol. Following treatments, mosquito population reductions and service request changes were evaluated. For aerial applications, the organophosphate naled was used, while ground applications used the pyrethroid Aqualuer® 20-20. Buffer aerial applications averaged 668.5 ha, significantly smaller than full aerial treatments (3750.2 ha). Cost and volume for buffer applications were notably lower ($1,998.47 and 34.1 liters) than full treatments ($10,558.40 and 180.6 liters). Mosquito populations posttreatment showed a 63.6% reduction for buffer applications, 59% for full aerial applications, and a 52% increase for ground-based treatments. Service request reductions were varied, with a slight increase (0.13%) after buffer aerial treatments and substantial reductions after full aerial (29.4%) and ground applications (87.5%). Buffer aerial applications demonstrated potential as an effective and cost-efficient method for mosquito control in targeted habitats. Although further evaluations are essential, such strategies could reshape mosquito management practices in regions similar to the Anastasia Mosquito Control District of St. Johns County.
