Abstract
In current society, smart clothing technology has become a critical way to improve the life quality of the elderly. This work conducted a category product evaluation and user demand system through the bibliometrics method, product evaluation analysis, focus group interviews and questionnaires. Based on the system, we designed smart clothing from the aspects of the clothing structure, hardware, software program and intelligent terminal platform to meet the needs of disabled elderly people and their caregivers in multiple scenarios. According to the test results of the smart clothing, the average error of temperature and humidity monitoring is 0.20°C and 2.88%RH. The time of putting on-taking off clothing in 6 representative daily scenarios was reduced by 51.67%. The daily body checking times, uncomfortable behaviours, and the anxiety of caregivers was decreased by 42.31%, 28.52% and 74.37%. Compared with ordinary clothing, six of the eight comfort performances are basically the same, and two are slightly worse.

В работе представлены результаты исследования применения сольватотермического способа нанесения n-CuO на поверхность компонентов пиротехнических составов в качестве модификатора скорости горения. Разработан способ нанесения n-CuO на поверхность неорганических солей. Данный способ позволил расширить номенклатуру веществ (применяемых в пиротехнике) для поверхностной модификации. Проведены эксперименты по нанесению n-CuO на поверхность наиболее распространенных в пиротехнике неорганических окислителей, таких как нитрат и перхлорат калия. Поверхность модифицированных образцов была исследована методом SEM, результаты которого подтверждают образование наноразмерного оксида меди (II). Модифицирование поверхностей неорганических солей приводит к изменению их характеристик тепловой стабильности, исследование которых производились методами TGA/DSC. Произведенная модификация приводит к изменению скорости горения пиротехнических составов. Применяемый в работе способ модификации показал, как катализирующий, так и ингибирующий скорость горения эффект, который зависит от природы модифицируемого вещества.
The paper presents the results of a study of the application of the solvothermal method of applying n-CuO to the surface of the components of pyrotechnic compositions as a combustion rate modifier. A method has been developed for applying n-CuO to the surface of inorganic salts. This method made it possible to expand the range of substances (used in pyrotechnics) for surface modification. Experiments were carried out on the deposition of n-CuO on the surface of the most common inorganic oxidizers in pyrotechnics, such as potassium nitrate and perchlorate. The surface of the modified samples was studied by SEM, the results of which confirm the formation of nanosized copper oxide (II). Modification of the surfaces of inorganic salts leads to a change in their thermal stability characteristics, the study of which was carried out by TGA/DSC methods. The modification made leads to a change in the burning rate of pyrotechnic compositions. The modification method used in the work showed both a catalytic and an inhibiting burning rate effect, which depends on the nature of the modified substance.

В работе рассматривается влияние числа Рейнольдса на площадь вихревой зоны, возникающей при течении полимерного расплава на входе в щелевой канал. Для нахождения полей скорости, напряжений и давления плоского течения полимерного расплава в сходящемся канале используется модифицированная реологическая модель Виноградова-Покровского, основанная на микроструктурном подходе к описанию динамики полимерной жидкости. Сама реологическая модель получена при применении методов статистической механики к суспензии невзаимодействующих упругих гантелей, при этом коэффициент трения носит тензорный характер и определяется размерами и формой макромолекулярного клубка. Расчеты течения полимерного расплава проводились методом конечных элементов с разделением по физическим процессам. Результаты расчетов показали, что при переходе из резервуара в щелевой канал происходит увеличение скорости, вместе с тем зависимость скорости проходит через максимум, который наблюдается в непосредственной близости от входа в щелевой канал, при этом сравнения с экспериментами дает удовлетворительный результат. В численном эксперименте показано, что зависимость размеров вихря от числа Рейнольдса носит монотонный характер с уменьшением размера вихревой зоны.
he paper considers the effect of Reynolds number on the area of the vortex zone arising from the flow of polymer melt at the entrance of the slot channel. The modified Vinogradov-Pokrovsky rheological model, based on the microstructural approach to describing the dynamics of polymer fluid, is used to find the fields of velocity, stresses and pressure of the plane flow of polymer melt in a converging channel. The rheological model itself is obtained by applying the methods of statistical mechanics to a suspension of non-interacting elastic dumbbells, with the friction coefficient being tensorial in nature and determined by the size and shape of the macromolecular ball. Calculations have shown that there is an increase in velocity at the transition from the reservoir to the slot channel, at the same time, the velocity dependence passes through a maximum, which is observed in the vicinity of the slot channel entrance, while comparison with the experiments gives satisfactory results. The calculations of the polymer melt flow were performed by the finite element method with separation by physical processes. The numerical experiment shows that the dependence of vortex size on Reynolds number has a monotonic character with increasing size of the vortex zone.

Rutting Prediction of Hot Mix Asphalt Mixtures Modified by Nano silica and Subjected to Aging Process
Authors: Taher Zainab Kadhim , Ismael Mohammed Q. 
Published: December 2022

High-volume traffic with ultra-heavy axle loads combined with extremely hot weather conditions increases the propagation of rutting in flexible pavement road networks. Several studies suggested using nanomaterials in asphalt modification to delay the deterioration of asphalt pavement. The current work aims to improve the resistance of hot mix asphalt (HMA) to rutting by incorporating Nano Silica (NS) in specific concentrations. NS was blended into asphalt mixtures in concentrations of 2, 4, and 6% by weight of the binder. The behavior of asphalt mixtures subjected to aging was investigated at different stages (short-term and long-term aging). The performance characteristics of the asphalt mixtures were evaluated using the Marshall stability, flow, and wheel tracking tests. Field Emission Scanning Electron Microscopy (FESEM) was utilized to understand the microstructure changes of modified asphalt and estimate the dispersion of NS within the asphalt. The results revealed that using NS–asphalt mixtures as a surface layer in paving construction improved pavement performance by increasing stability, volumetric characteristics, and rutting resistance before and after aging. The FESEM images showed adequate dispersion of NS particles in the mixture. Results indicated that adding 4% of NS to asphalt mixtures effectively enhanced the pavement’s performance and rutting resistance. Doi: 10.28991/CEJ-SP2023-09-01 Full Text: PDF

Published: December 2022

Background The frequent disruption to the delivery of education and the switch to online learning amidst the COVID-19 pandemic affected students’ mental health. The objectives of the study were to explore the levels of anxiety, depression, somatic symptoms, and stress among students during the COVID-19 pandemic and their associations with sociodemographic status, clinical teaching, and concerns about COVID-19. Methods A cross-sectional study was conducted using convenience sampling via an online self-administered questionnaire-based survey with 285 participants. The survey included questionnaires on sociodemographics, anxiety, depression, somatic symptoms, and stress levels using a validated questionnaire. Data was analyzed using Spearman’s correlation test and ordinal logistic regression to identify correlations between psychological well-being and the effectiveness of e-learning. Results More than half of the students reported anxiety (57.2%), depression (58.6%), somatic symptoms (54.4%) and moderate to high stress (79.7%) during the pandemic. Students who stated that online role players were not helpful had increased anxiety levels (rho=-0.18, P=0.005). However, somatic symptoms were reduced among students who found campus role players helpful (rho=0.16, P=0.012). More than half the participants (55.8%) felt that they were supported by the university during the COVID-19 pandemic, although most students (91.6%) sought clear information and prompt updates from the university. We found that students with psychological distress experiencing anxiety (OR=2.47, 95% confidence interval, CI=1.49-4.08), depression (OR=3.22, 95% CI=1.94-5.34), somatic symptoms (OR=2.94, 95% CI=1.76-4.91, P<0.001), and stress (OR=3.08, 95% CI=1.76-5.41) would value more mental health support from the university. Conclusions The university should consider increasing campus role-play sessions and providing prompt updates and mental health resources to help students cope better psychologically during the pandemic.
