Mathematical Analysis of Peristaltic Pumps for Fene-P model subject to Hall and Joule impact
Authors: Hasen Saba S. , Kareem Rabiha S. , Ali Hayat A. 
Published: October 2022

A mathematical model is developed to discuss the impact of the Hall current and the Joule heating on the peristaltic flux of finitely extensible nonlinear elastic Peterlin (FENE-P) fluid in a tapered tube with mild stenosis. The fluid movement along the wall surface resulted from the sinusoidal wave flowing with constant speed. Conditions of velocity and thermal slip are applied. Lubrication approximation is adopted to modify the governing flow problem. To discover the solution to a system of equations, the regular perturbation approach is used. The effects of the different physical parameters are debated and graphically shown in a set of figures. It is discovered that as the Hall current parameter is increased and the Hartman number is decreased, the fluid velocity increases. It is also worth noting that the Dufour number causes the fluid temperature to rise, whilst the Hall current parameter causes the temperature to fall. In the meantime, both the Hall current parameter and the Soret number have the opposite effect on concentration. The trapping phenomenon is thoroughly investigated.

Published: October 2022

The creation and characterization of laser-generated plasma are affected by laser irradiance, representing significant phenomena in many applications. The present work studied the spectroscopy diagnostic of laser irradiance effect on Zn plasma features created in the air by a Q-switched Nd: YAG laser at the fundamental wavelength (1064nm). The major plasma parameters (electron temperature and electron density) have been measured using the Boltzmann plot and the Stark broadening methods. The value of electrons temperature ranged from 6138–6067 K, and the electron density in the range of 1.4×1018 to 2×1018 cm-3, for laser irradiance range from 2.1 to 4.8×108 (W/cm2). The McWhirter criterion for preserving a local thermodynamic equilibrium (LTE) condition is confirmed in this study. Furthermore, other fundamental plasma parameters, such as Debye length (λD), number of particles in Debye sphere (ND), and plasma frequency (ωp), were measured. We found that all plasma parameters are affected by laser intensity.

Objectives:
Non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM) strongly coexist as they share common pathophysiological conditions. Several non-invasive, patient-friendly, and cost-effective liver fat indices have been introduced recently to diagnose NAFLD at an early stage. This study aimed to establish the correlation between ultrasonography and liver fat indices (fatty liver index [FLI] and hepatic steatosis index [HSI]) to determine NAFLD among known T2DM patients.

Material and Methods:
A cross-sectional study was conducted using one hundred newly diagnosed type 2 diabetic patients attending the diabetic and endocrinology clinic at the Colombo South Teaching Hospital, Kalubowila, Sri Lanka. An interviewer-administered questionnaire was used to collect socio-demographic data and anthropometric measurements. Ultrasound scans were performed to diagnose and stage fatty liver. Biochemical investigations included aspartate amino transferase, alanine aminotransferase, gamma-glutamyl transferase triglyceride analysis. Scores for the liver fat indices were calculated using collected data and correlations between the variables were statistically analysed using the statistical software, SPSS version 23.0. Descriptive statistics, chi-square tests, Independent t-tests and Pearson correlation were used in the data analysis.

Results:
The incidence of NAFLD among T2DM was 82%. There was a statistically significant correlation (P < 0.05) between NAFLD diagnosed by ultrasonography and HSI. There was also a statistically significant correlation (P < 0.001) between NAFLD diagnosed by ultrasonography and FLI, and there was a statistically significant difference between FLI among participants with no fatty liver compared to participants with ≥ grade 2 fatty liver (P < 0.001.

Conclusion:
The current study showed that both FLI and HSI can be used as markers for the early diagnosis of NAFLD in T2DM patients.

Цель исследования — разработать адаптивную технологию возделывания смешанных бобово-злаковых травостоев на основе фестулолиума для производства сбалансированных по сахаропротеиновому отношению кормов. Полевые опыты проводили в Ивановской области на стационаре отдела кормопроизводства Ивановского НИИСХ. Закладка полевого опыта была проведена в 2015 году. В результате сравнительного изучения традиционных и новых кормовых культур в одновидовых и смешанных посевах на дерново-подзолистых почвах установлено, что фестулолиум в одновидовых посевах за два укоса обеспечивал в контроле сбор зелёной массы 24,8 т/га, на фоне минерального питания — 33,6 т/га, что в 1,2‒1,3 раза больше, чем тимофеевка, в смешанных посевах с клевером — 68,1 т/га зелёной массы, 9,54 т/га сухой массы, 8630 корм. ед. и 898 кг/га переваримого протеина, с люцерной — соответственно 60,3, 10,3, 8770 и 1050, что на 14‒17% больше, чем в посевах с тимофеевкой. На фоне минерального питания продуктивность клеверо-фестулолиумных смесей составила 71,6 т/га зелёной массы, 10,9 т/га сухого вещества, 9960 корм. ед. и 1009 кг/га переваримого протеина, люцерно-фестулолиумных — 60,3, 10,3, 8770 и 1050 соответственно. В травосмесях с фестулолиумом полученная зелёная масса отличалась высокой питательностью и сбалансированностью по белку и углеводам, содержание переваримого протеина и сахара находилось в пределах физиологической нормы или превосходила её, что нельзя сказать о традиционных травах.
The investigation aimed at development of region-specific cultivation technology for legume-gramineous mixtures with festulolium in order to obtain feeds, balanced in sugar-to-protein ratio. Field trials took place in the Ivanovo region in 2015. Competitive testing of conventional and new crops as monocultures and grass mixtures on sod-podzolic soil showed that festulolium monoculture gave 24.8 t ha-1 of green mass for two cuts in the control and 33.6 t ha-1 — after mineral fertilization, exceeding common timothy by 1.2‒1.3 times. Festulolium-clover mixture produced 68.1 t ha-1 of green mass, 9.54 t ha-1 of dry mass, 8630 feed units and 898 kg ha-1 of digestible protein, while festulolium-alfalfa mixture — 60.3, 10.3, 8770 and 1050, respectively, exceeding timothy mixtures by 14‒17%. Clover-festulolium mixture on the background of mineral nutrition provided 71.6 t ha-1 of green mass, 10.9 t ha-1 of dry mass, 9960 feed units and 1009 kg ha-1 of digestible protein, while alfalfa-festulolium combination — 60.3, 10.3, 8770 and 1050, respectively. Green mass of festulolium mixtures had high nutritional value and good balance in protein and carbohydrates. Contents of digestible protein and sugar met physiological standard or exceeded the latter. Conventional grasses showed worse results.

Обновление парка мелиоративных машин и расширение площадей земель в ходе коренного улучшения неиспользуемой деградированной залежи являются двумя взаимосвязанными направлениями. Они могут быть реализованы в ходе внедрения научно обоснованной современной «Системы машин для комплексной механизации мелиоративных работ», наиболее полно отвечающей задаче проведения мониторинга рынка и обновления парка землеройных, ирригационных, каналоочистительных машин и специальных мелиоративных средств. В статье представлен обзор реализации «Системы машин» в период с 1955 года до настоящего времени, создания современного комплекса машин для технологий восстановления деградированных пахотных и кормовых угодий. Установлено, что восстановление эффективного функционирования мелиоративной сети и гидротехнических сооружений с одновременным повышением плодородия малопродуктивных угодий позволяет сократить прирост деградированных земель и подтверждает актуальность разработки новых способов комплексной мелиорации с применением энергонасыщенных комбинированных агрегатов и многофункциональных специальных мелиоративных машин. Показаны варианты технических средств с адресной обработкой кормовых угодий. В результате исследований определены основные прогнозные показатели комбинированных агрегатов и обоснована область их использования в ресурсосберегающих технологиях с обработкой горизонтов без выноса продуктов химических реакций в водоёмы и реки.
Fundamental improvement of degraded unused lands combines the development of new machines for land reclamation and increase of cultivated land area. This can be achieved through the introduction of modern “Machinery system for complex mechanization of melioration process”. This system has to be tested experimentally and enable effective market monitoring and renovation of earthmoving, irrigation and ditch cleaning machines as well as specific ameliorative equipment. This report gives overviews of “Machinery system” in the period from 1955 up to now and development of modern machinery complex, aiming at reclamation of degraded fields and forage lands. Effective functioning of ameliorative system and hydrotechnical structure in combination with improvement of soil fertility reduces formation of degraded lands. It proves the relevance of new method development for complex melioration, using energy-efficient combined cultivating and multi-functional ameliorative machines. The paper shows some equipment for targeted tillage of forage area. Investigations estimated main parameters of combined machines and described the area of their application as a part of resource-saving technology. This technology stands for the cultivation of soil horizon, keeping products of chemical reaction away from water reservoirs and rivers.
Numerical simulation of natural vibrations of a cylindrical shell partially filled with fluid and embedded in an elastic foundation
Authors: Бочкарёв Сергей Аркадьевич 
Published: October 2022

Представлены результаты исследований собственных колебаний круговых цилиндрических оболочек, полностью или частично заполненных неподвижной жидкостью и лежащих на упругом двухпараметрическом основании Пастернака. Поведение упругой конструкции и сжимаемой жидкости описывается в рамках классической теории оболочек и уравнений Эйлера. Уравнения движения оболочки, как и акустическое волновое уравнение, сводятся к системам обыкновенных дифференциальных уравнений. Решение сформулированной краевой задачи осуществляется методом ортогональной прогонки Годунова. Проанализированы зависимости минимальных частот колебаний от характеристик упругой среды с разными вариантами неоднородности по длине тела при различных уровнях заполнения оболочки жидкостью. Продемонстрировано, что с повышением уровня заполнения оболочек жидкостью влияние упругого основания на частотный спектр конструкции снижается.
The paper presents the results of studies on natural vibrations of circular vertical cylindrical shells completely or partially filled with a stationary compressible fluid and embedded in a Pasternak two-parameter elastic foundation. In the meridional direction, the elastic medium is both homogeneous and inhomogeneous, and is an alternation of areas, in which this medium is present or absent. The behavior of the elastic structure and compressible fluid is described within the framework of classical shell theory based on the Kirchhoff - Love hypotheses and the Euler equations. The equations of motion of the shell combined with the corresponding geometric and physical relations are reduced to a system of ordinary differential equations for new unknowns. The acoustic wave equation is also reduced to a system of ordinary differential equations using the straight line method. The formulated boundary value problem is solved by the Godunov orthogonal sweep method involving the numerical integration of differential equations by the fourth order Runge - Kutta method. The natural frequencies of vibrations are calculated using a combination of stepwise procedure and subsequent refinement by the half-division method. The validity of the obtained results is confirmed by comparing them with the known numerical-analytical solutions. The dependences of minimum vibration frequencies versus the level of fluid are analyzed for simply supported, clamped and cantilevered cylindrical shells of various types of inhomogeneity along the length of the body and with different stiffness. It is demonstrated that with increase in the level of filling of shells with fluid, the influence of the elastic foundation on the frequency spectrum of the structure decreases.

Предложены различные способы повышения производительности мобильных терминалов за счет высоких скоростей, низких стоимости и энергопотребления. Действительно, более высокие скорости подразумевают более проблемные каналы передачи, что делает работу приемников более обременительной. Нас интересует решение классической задачи обнаружения линейной смеси гауссовых шумов для телекоммуникационных систем LTE по зашумленному наблюдению входного сигнала, смешанного с известной матрицей, представляющей поведение канала. Требуется найти вектор, который минимизирует евклидово расстояние между зашумленным выходом и бесшумным. Частотное разнообразие систем LTE очень велико. В этом контексте рассмотрена производительность традиционных эквалайзеров (ML, ZF, MMSE), предложен PSO (Particular Swarm Optimization) - метод обнаружения с почти оптимальной производительностью с точки зрения частоты ошибок по битам BER 10 для SNR 16 дБ.
This study suggests various ways to improve the performance of mobile terminals at fast speeds, cheap cost, and low power consumption. Indeed, higher rates imply more problematic transmission channels, making receivers’ jobs more onerous. We’re interested in solving the classic problem of detecting a linear mixture of Gaussian noise for LTE telecommunication systems from a noisy observation of an input signal mixed with a known matrix representing the channel’s behavior; we’re looking for the vector that minimizes the Euclidean distance between the noisy output and the noiseless one. The frequency diversity of LTE systems is very high. In this context, we look at the performance of traditional equalizers (ML, ZF, MMSE) in the first part. In the second section, we offer PSO (Particular Swarm Optimization), a detection method with near- optimal performance in terms of bit error rate BER 10 for SNR of 16 dB, which is extremely close to ML.

Published: October 2022

Background To address the rising non-communicable diseases (NCDs) in Malaysia, the Better Health Programme Malaysia (BHP MYS) engaged and trained community health volunteers (CHVs) to undertake health promotion activities with poor urban communities in Kuala Lumpur to reduce their NCD risk. This study evaluates the extent that the capacity-building programme achieved the objectives of increasing knowledge and confidence in NCD prevention and adopting personal lifestyle changes. Methods A capacity-building programme was designed to emphasise active learning approaches and blended learning (in-person and digital) and was delivered between January to December 2021 (during the Malaysian Government “Movement Control Orders” in response to the COVID-19 pandemic). Thirty CHVs participated in the capacity-building programme. A mixed methods evaluation approach was used, including quantitative surveys and routine data, focus group discussions, and semi-structured interviews. Findings Community Health Volunteers increased their NCD knowledge (85.2% provided correct answers in post-programme assessment compared to 43.3% at pre-programme assessment), made changes to their dietary and physical activity practices (100%), and adopted new engagement techniques, particularly a digital social influencer role for NCD behaviour change. The most important factors for sustaining participation were individual motivation and a supportive environment. CHVs were satisfied with the blended in-person-digital approach and perceived that the usefulness and applicability of the health information received was the primary benefit across all delivery modes. Cohort-based, active learning approaches and actionable messages can encourage learning retention and facilitate application. Dedicated technical support and ‘job aid’ tools are required for CHVs to perform and sustain NCD prevention roles effectively. Conclusions The capacity-building programme effectively increased CHV capacities to address NCDs in their own lives and communities and was acceptable to CHVs. The findings suggest the value of cohort-based, active learning approaches in building capacity. Expanding on capacity-building and sustaining involvement are important considerations for this cohort and, in general, for health volunteer capacity-building in Malaysia and elsewhere.
