Nonlinear regimes of electric convection of poorly conducting fluids in weightlessness at low frequencies of an electric field
Authors: Il’in V. A.
Published: October 2024

Electrothermal convection in a poorly conducting fluid in an alternating electric field of a horizontal capacitor is studied. The nonlinear regimes of electric convection in weightlessness are studies at low frequencies of the electric field on the basis of the pentamodal model within the framework of the electroconductive charge formation mechanism. Hysteresis transitions between two different synchronous and subharmonic regimes are found to exist. Transitions to chaos occur by means of either interemittance or a subharmonic cascade.
Self-similar solution of the first Stokes problem for non-Newtonian fluids with power-law viscosity
Authors: Kolodezhnov V. N.
Published: October 2024

The first Stokes problem is considered for flows of non-Newtonian fluids with effective viscosity varying in accordance with the power law. Self-similar solutions are constructed for the fluids, whose mechanical behavior is described by the Ostwald – de Waele and Herschel–Bulkley rheological models with the corresponding restrictions on the nonlinearity degree exponent n. It is shown that for the Ostwald – de Waele fluid self-similar solutions exist only for 0 n 1, which corresponds to the pseudoplastic behavior. At the same time, self-similar solutions for the Herschel–Bulkley fluid can be obtained only at n 1, when this fluid exhibits the properties of dilatancy.

Published: October 2024

Rapid development of the anomalous enhancement of separated turbulent Re = 6000 air flow and heat transfer in an in-line single-row package of 31 inclined grooves, 0.2 in dimensionless depth, in a singled-out longitudinal region of the wall of a narrow channel is studied. It is due to the interference of vortex wakes behind the grooves and the acceleration in the channel flow core with the formation of a zone of ultrahigh longitudinal velocity. The wave-shaped parameter characteristics are stabilized in the region of approximately 15th groove, whereupon the oscillation amplitudes are moderately reduced. The return flows in the grooves are enhanced with distance from the entry section, the minimum negative friction diminishing from −2 to −4. The total relative heat removal from the structured region increases atq= const by a factor of approximately 2.75 and by the factor of two atT= const with increase in the relative hydraulic losses by the factor of 1.7, as compared with the case of a plane–parallel channel. The relative heat removal from the surface bounded by the contour of the 20th inclined groove amounts to 3.7 (q= const) with increase in the hydraulic losses by the factor of 2.2. An increase in the local maximum of the longitudinal velocity up to a factor of 1.5, as compared with the mean-mass velocity, can be observable.

Published: October 2024

A new method of determining the dimensions and shapes of polymer molecules in solutions is proposed and verified in experiments. The method is based on the measurements of the relaxation of the transverse magnetization intensity of nuclei. It is established that the decaying signal of the spin echo from elongated molecules contains two terms exponentially decaying with time, which correspond to two diffusion coefficients differing by a factor of about two. The signal from molecules with a near-spherical shape contain only one exponent.

Published: October 2024

Hydrodynamic flows induced by translational oscillations of cylindrical bodies of various cross-sectional shapes are studied. The motion of fluid around oscillating bodies is described using the system of Navier–Stokes equations written in a generalized curvilinear coordinate system. Transition to a given body shape is implemented using a conformal mapping. The problem is solved using the method of successive asymptotic expansions under the assumption that the oscillation amplitudes are small. In each asymptotic approximation, the subproblems are solved numerically using the finite-difference method. Based on the results of the work, estimates of the hydrodynamic effect are obtained, the applicability of the high-frequency asymptotic approximation is estimated, and secondary stationary flows near cylinders are studied, in particular, the occurrence of directed stationary flows near an oscillating asymmetric body is considered with reference to the Joukowski airfoil.

Published: October 2024

Historically, males have dominated the policy domain, and women have held more direct practice roles; therefore, male analysts do not use a gender lens in formulating a policy or strategy paper. Similarly, the Bangladesh government, with a working group predominantly composed of men, created the National Menstrual Hygiene Management Strategy 2021 for the first time to ensure that "no girl or woman is left behind" in exercising their fundamental rights. This study's goal, from a feminist perspective, was to evaluate the extent to which the government has overcome patriarchal restraints in the development of eight strategies for menstruation. Following the qualitative approach, we used the desk research method to review the strategy. This analysis shows that the strategy refollows patriarchal norms resulting in menstruation being considered a social phenomenon rather than a biological phenomenon.

Authors: Barge Sonal , Gerardine Mary
Published: October 2024

The motive of designing a low-power system is to have a long battery life. One can carefully apply low-power design techniques to achieve low power consumption with proper system functioning to increase battery life. One such system where many devices are generally battery-operated and connected to the internet is the Internet of Things (IoT). IoT devices are used widely to gather data to propel actions and transmit the data for data analysis, connectivity, and automation. So much research is focused on IoT communication and computation in IoT devices, which increases power consumption. This survey explores low-power design strategies used at the architectural level. Additionally, it highlights the IoT features that give opportunities to apply low-power design methodologies to achieve less power consumption in IoT. Low-power design techniques are critical for the efficient functioning of Internet of Things (IoT) applications, where devices often operate in resource-constrained environments with limited power sources like batteries. Many applications of IoT are noticed including the domains such as industry, environment, and society, which are highly power-consuming because of the features such as computation, communication, security, and fault tolerance. Researchers have already reported the usefulness of many such techniques including architecture-level low-power design techniques. Still, it is observed that the work carried out is inadequate regarding power consumption, and communication bandwidth bottlenecks. In the present work, a rigorous literature survey is carried out based on low-power design techniques to support sustainable growth of IoT applications across various domains and power optimization.

Authors: Long Siyu , Ang Mei Foong , Mohd Noris Norowi
Published: October 2024

As a traditional Chinese folk instrument with a history of 2,000 years, the pipa has been valued by the Chinese government and favored by the Chinese people for its unique sound and rich expressive power. However, the development lineage and current status of pipa education in China have rarely been clarified, especially the current status of pipa education. This study used narrative review techniques to organize and analyze the history and current status of pipa education. This paper reviews the history of pipa education in China, focusing on the current development of pipa education, including teaching institutions, representative figures, target students, and teaching models. The study revealed that contemporary Chinese pipa education has achieved remarkable accomplishments. China’s eleven conservatories serve as the primary institutions for imparting contemporary pipa education. Representative figures such as Lin Shicheng, Wang Fangdi, and Liu Dehai have made substantial contributions to the advancement of contemporary pipa education. However, pipa instruction is primarily targeted toward children and university students, with limited emphasis on elderly people and special children. Individual and group lessons in traditional pipa instruction possess their respective merits and drawbacks. Nonetheless, further exploration is warranted regarding integrated teaching models and the application of contemporary information technology in innovative teaching models to facilitate the advancement of modern pipa education.

Authors: Chakraborty Anurag , Dhok Archana , Anjankar Ashish , Vagga Anjali , Jha Roshan Kumar
Published: October 2024

Since preeclampsia first emerged a few centuries ago, a substantial portion of humanity has been tormented by this disease, which has jeopardized and disrupted mankind. Numerous biological markers, including ENDOGLIN, PIGF (placental growth factor), SFLT 1(soluble fms like-tyrosine kinase 1), and PAPP-A (pregnancy associated plasma protein-A), suggest preeclampsia. It was beneficial for detecting preeclampsia, even if there was frequent mortality and morbidity among mothers because of the anticipated latency. Then another marker, fibronectin, was added to the picture. A better preeclampsia prognosis leads substantially to an overall decrease in maternal morbidity and mortality. The primary organ that manufactures circulating fibronectin, occasionally referred to as serum fibronectin, is the liver.  To enable the extracellular and intracellular matrix to communicate and regulate cell behavior, fibronectin, an extracellular matrix element, primarily interacts with integrin receptors. Fibronectin is a diagnostic marker for a variety of ailments, such as muscular dystrophy, ovarian and stomach cancers, and gestational diabetes. Inflammatory changes result in the release of fibronectin into the bloodstream, and the main triggering factor of preeclampsia is the infiltration of various trophoblasts that injures endothelial tissues and induces inflammation. Therefore, the primary goal of our study was to establish that fibronectin is a biomarker of preeclampsia. To elucidate our perspective and evaluate whether fibronectin is relevant in preeclampsia prediction, we will conduct a qualitative evaluation of prior research and juxtapose it with the findings of the present study. Thus, early detection of preeclampsia could decrease the rate of maternal mortality and morbidity.

Authors: Kumari Shalini , Shukla Balvinder , Mishra Paritosh
Published: October 2024

The workplace environment experienced tremendous transformation after the worldwide pandemic, with the hybrid model emerging as the most significant paradigm. For a considerable duration, organizations have faced challenges in creating an optimal work environment that fosters heightened productivity, well-being, employee performance, and overall job satisfaction. The present study aims to explore the transformation journey from crisis-induced hybrid work to the construction of a sustainable post-pandemic work environment, as well as the significant impact of the hybrid workplace on employee performance and job happiness. The researchers employed a quantitative method to collect data from 260 employees working in a hybrid work setting. Partial least squares structural equation modeling was applied to assess the data and examine the hypotheses. The findings indicate that hybrid work has a significant and positive effect on employee performance and job happiness. It also appears that hybrid work has a positive effect on work engagement and that work engagement considerably mediates the relationship between hybrid work and employee performance. However, the findings do not support the direct effect of hybrid work on job happiness, but rather the mediating role of work engagement in the proposed relationship between hybrid work and job happiness. The research introduces fresh insights by linking the hybrid workplace model to employee performance, job satisfaction and work engagement. Additionally, it extends the JD-R model into the hybrid workplace context. The practical implications of this study suggest that practitioners can leverage these findings to inform the development of policies and procedures aimed at enhancing employee performance and job satisfaction, particularly within the framework of the hybrid workplace model.

Published: October 2024

Pedicle screw placement is a vital scoliosis therapy operation that aims to address spinal abnormalities while avoiding consequences including neurological damage caused by misplaced screws. Accurate imaging is required for precise screw insertion, with intraoperative CT (O-arm) and fluoroscopy (C-arm) being the principal modalities used. This review assesses various modalities based on their radiation dosages and accuracy. It comprises research published between 2012 and 2020 that evaluates both effective dose and accuracy for pediatric and adult patients. According to the review, the O-arm outperforms the C-arm in terms of accuracy, resulting in shorter procedure times for both pediatric and adult patients. The O-arm's sophisticated 3-D imaging capacity enhances screw insertion accuracy, reducing the likelihood of problems and the need for additional procedures. Furthermore, using pediatric low-dose protocols and techniques like the Detachable Pedicle Marker and Probe (DPMPs) with pulsed fluoroscopy can reduce radiation exposure while still ensuring precise screw placement. The review suggests that the O-arm has considerable advantages over the C-arm, such as improved image quality and lower radiation risk. This leads to enhanced patient safety and procedural outcomes. Overall, the O-arm's capacity to produce high-quality 3-D pictures makes it an invaluable tool in pedicle screw insertion, resulting in more accurate surgical outcomes and reducing the risk of problems associated with spinal deformity repairs.

Interventional radiology (IR) has become a widespread medical imaging technique, offering minimally invasive treatment options. However, IR procedures can expose patients and staff to substantial radiation risks, necessitating enhanced radiation protection practices. This study aimed to survey the knowledge and practices of interventional radiology staff regarding radiation protection. A cross-sectional study with a descriptive aim, based on a questionnaire was done. The study subjects were all healthcare personnel of all specialties having practiced in interventional radiology between 2019 and 2022 at the University Hospital Center of Rabat. The statistical processing was carried out using Microsoft Excel 2013® and the IBM SPSS Statistical program version 20 (IBM Inc. NY, USA).  The results indicated that 59.4% of participants had not received any specific training in radiation protection, and 45% were unaware of the radiation-induced risks associated with interventional radiology procedures. Regarding safety practices, 75% of participants maintained a distance of at least 1 meter from the x-ray source, while only 6% used the lowest possible exposure settings. Concerning the use of radiation protection devices, 87.5% of participants wore a lead apron, 75% used a thyroid shield, 6.3% wore lead glasses, and 37.5% utilized suspended mobile screens, whereas 12.5% did not use any radiation protection devices. Additionally, 84% of participants wore their personal dosimeter, though not consistently. The knowledge and practices of most interventional radiology personnel are inadequate for effective radiation protection. Regular, ongoing training in radiation safety is essential to improve adherence to protection standards and enhance overall safety in clinical practice.

Pain is one of the main reasons why a patient is required to appear at the emergency department. According to the literature, one of the main factors leading to inadequate nursing care of pain has been inadequate assessment of the pain threshold, delay in interventions, and poor knowledge of the nursing staff. This study aimed to explore and describe emergency nurses’ experiences during pain management and identify the barriers they encounter when providing this care. A qualitative study, with a focus group composed of 10 nurses, through open questions, was conducted in April 2023 at the emergency nurses of the Regional Hospital "Xhaferr Kongoli" Elbasan. The questions were designed based on the literature and included the evaluation of the method of pain management in the emergency room, the interventions of nurses, the obstacles that nursing staff face during patient care, and the way to address these obstacles. The duration of the interviews ranged from 25 to 35 minutes. Demographic data were analyzed using descriptive statistics, and interview data were analyzed by qualitative thematic analysis. Ten nurses were interviewed, with a mean age of 40.1 years and 7.3 years of work experience in the emergency department. The thematic analysis of the data identified three main themes and subthemes, including Management of situations, Planning, and Challenges. Our study identified nurses' experiences in planning interventions for patients with pain. Early protocol-based pain management can improve patient outcomes and reduce inappropriate interventions. More research is needed to identify these interventions and examine how they interact with ineffective pain management. More studies are needed to highlight the role of nurses in pain assessment and pain management in emergency departments.

In contemporary times, plastic waste recycling has emerged as a crucial trend, presenting significant potential for plastic reformulation and recyclability. Waste plastic, owing to its high calorific value and abundance, serves as a promising energy source. Through the pyrolysis process, plastic waste can be converted into pyrolysis oil, which exhibits properties akin to conventional diesel fuel and can be seamlessly integrated into engines. This study investigates the synthesis of waste plastic oil (WPO) via pyrolysis using a diverse feedstock comprising various types and grades of plastic. The resulting oil, resembling diesel in characteristics, is evaluated for its performance in a compression ignition (CI) engine equipped with a variable compression ratio.Experimental tests are conducted using blends of WPO and diesel ranging from 0% to 100%, across different engine loads spanning from partial to full load conditions (2 kg to 12 kg). The combustion characteristics, engine performance metrics, and emission profiles are meticulously analyzed and compared against those of conventional diesel fuel. The findings indicate that the engine exhibits comparable performance with WPO at higher loads, akin to that with diesel. However, at lower loads, an extended delay period is observed, contributing to engine stabilization.These results underscore the potential of renewable plastic oil as a viable alternative fuel for diesel engine applications, particularly under specific operating conditions. The study provides valuable insights into the feasibility and performance implications of integrating waste plastic oil into compression ignition engines, contributing to the ongoing discourse on sustainable energy solutions and waste management practices.
