Numerical Simulation of Rotational Speed Sinusoidal Pulsation for Enhancing Polymer Processing Based on Smoothed Particle Hydrodynamics

Vibration-assisted methods are playing a more and more important role in processing polymers for twin screw extruders (TSEs) in order to satisfy the increasing requirements for polymetric products in various applications, but existing vibrating technologies are usually restricted in school laboratories and industrial research rooms because of their drawbacks. The purpose of this study is to design a novel vibration method for TSEs. Numerical simulation was performed based on a meshless method, namely smoothed particle hydrodynamics (SPH). The velocity distribution, particle distribution, and pressure of particles in a co-rotating twin screw component in the conveying zone of a TSE are investigated in detail to recover the influence of the rotational speed excitation on the flow properties of both fully filled and partially filled states. The results show that cases under superimposed excitation can produce a more variable physical effect, thus enhancing and weakening the velocity field and the pressure field alternately. And on the whole, that effect could improve the particle distribution in according cases. These findings can lay a solid foundation for further study on the development and application of superimposed excitation technology in the polymer processing of TSEs.

A Simple Portable Handheld Van de Graaff Generator for Demonstrating Static Electricity

One device that is commonly used to demonstrate electrostatic phenomena is the Van de Graaff generator. However, this device is found to be expensive, relatively large, hard to move, and not available in many school laboratories. This paper aims to describe the experiment of creating a simple portable handheld Van de Graaff generator produced by employing second and easily available materials in the local market. This device collects charges from two materials that rub against each other. The combination of chosen materials listed in the triboelectric series determines the type of charge on the generator. This research used the experimental method by continuously testing the prototype to find the best result using the following steps: start, theory, design, material selection and assembly, testing, completion, and finish. A charge conduction experiment and a charge type test through a simple Coulomb experiment or an electrostatic polarity detector successfully tested the final product. The results showed that the device could effectively demonstrate basic electrostatic phenomena, making it a practical and affordable alternative for classroom demonstration.

Contribution of Infrastructural Availability for School Growth and Sustainable Improvement in Academic Performance in Selected Secondary Schools in Tororo District

ABSTRACTThe study sought to establish the contribution of infrastructural availability to school growth and sustainable improvement of academic performance in selected secondary schools in Tororo District. The study employed a qualitative approach, and data were collected from school administrators, the management team and teachers using open‐ended questions based on interviews. Results were analysed thematically and presented verbatively. Findings showed that teaching aids, such as lesson plans, blackboard rulers, chalkboards, and textbooks are available and help improve academic performance, but overcrowded classrooms, poor ventilation and small space compared with the number of learners for a particular class are linked to lower levels of student engagement and learning. Noise levels have a significant impact on both teacher and student performance, and proper levels of natural illumination increase test results and teacher and student moods. Lack of commitment leads to skipping school and failing to complete assessment tasks. It was concluded that the Ugandan government supports the building of classrooms, libraries and laboratories in schools; teaching aids, such as textbooks lesson plans, blackboard rulers and chalkboards, raise teachers' morale to hold classes consistently, which helps schools expand and sustain improvements in academic performance. However, classrooms have poor ventilation and are overcrowded because of large enrolments. It is recommended that the government should improve the school infrastructure by renovating the classrooms, providing desks for children, making supplementary funding available to low‐performing schools and providing teachers with accommodations at schools to check the late coming, early departure and regular absenteeism of teachers on duty.

Mentoring for the Diverse Range of Family Physicians' Engagement in Research.

Primary care researchers are increasingly at the forefront of developing innovations and new research methods to address complex issues in health care, including multi-morbidity, social determinants of health, health equity, managing population health in clinical practice, patient satisfaction, and provider burnout. Research demonstrates that "primary care is the only health care component where an increased supply is associated with better population health and more equitable outcomes."1 As a primary care specialty, family medicine has evolved beyond its initial focus on clinical practice and education to realizing the imperative for the discipline to robustly engage in research and embrace the responsibility to generate the evidence that drives changes in primary care practice and policy.2 The primary care clinic is increasingly seen as a complement to medical school laboratories as a powerful site for developing new evidenced-based medicine, and essential for translating new clinical knowledge into practice. Practice-Based Research Networks (PBRNs) comprising primary care clinicians working in the "real world" of clinics promise to bridge "the gaps between communities, funders and policy makers"3 and the National Institutes of Health has shown increased interest in strengthening Clinical Translational Science Awardees' collaborations with PBRNs.4 Despite primary care's proven ability to deliver improved outcomes at a lower cost, not enough family physicians are currently engaging in research to improve practice and inform policy. This commentary attempts to describe the wide range of family physicians' intensity of involvement in primary care research and the prospects of mentoring for these needs.

The Impact of the Lack of Chemistry and Physics Laboratories in Schools

The deficiency of chemistry and physics laboratories in schools has profound implications for scientific education, as illuminated by a study conducted in Covasna County. Deprived of laboratory access, students lack the opportunity to experiment with chemical and physical phenomena, limiting the application of theoretical knowledge. This shortfall may foster a superficial understanding of the subjects and potentially dampen enthusiasm for science. Moreover, the absence of exposure to laboratory equipment and techniques stunts the cultivation of practical and critical skills crucial for scientific or technical careers, hindering students’ preparation for future pursuits in these fields. Practical skills and a deep comprehension of scientific principles are indispensable for success in such careers. The absence of laboratory experience may place students at a disadvantage in university admissions or job competitions. It is imperative to implement viable solutions - investments in laboratory infrastructure, additional training for educators, and the development of interactive learning programs compensating for the dearth of practical experience. Integrating modern technology into the educational framework offers alternative avenues for experimentation and practical learning, mitigating the absence of physical laboratories. The study, conducted via an online questionnaire involving 61 school respondents, underscores the adverse impact of lacking chemistry and physics laboratories on students’ learning and development. However, by implementing solutions, the situation can improve, ensuring students receive comprehensive and equitable science education. Addressing this deficit is pivotal in nurturing the next generation of scientists and innovators, equipping them with the skills needed to tackle real-world challenges and contribute to scientific progress.

Holographic Technology in Stem Education and Training

Holograms provide unique opportunities to enhance students' understanding of intractable concepts and processes using engaging visualization methods. Portable 3D holographic fans allow for the improved visualization of molecules, structures, pathways, and other STEM - related content that have the potential to elevate information acquisition in novel ways that extend beyond 2 - D presentations and textbook figures. While the potentiality of this innovative technology is exciting, adopting 3D holographic materials in the STEM pedagogical and research environment requires producing literary evidence to justify usage in specific contexts and sufficient guidance on safety protocols. A review of 3D hologram technology revealed an inadequate amount of efficacy research. Quantitative and qualitative research studies involving STEM majors, faculty, and researchers constitute the engine that will drive the utilization of 3D hologram visualizations in STEM undergraduate, graduate, and professional school classrooms and laboratories. The current article reviews relevant research findings and discusses the potential impacts of 3D hologram technology in teaching, research, distance learning, and medical contexts.

Problem of Surface Waves on Water in Higher School Laboratory Workshop

Traditionally, in lecture courses on General Physics, the example of waves propagating on the water surface is used for the qualitative description of wave phenomena. At the same time, in corresponding laboratory courses, there are almost no quantitative tasks on the same topic, the purpose of which would be to measure the surface wave characteristics. The reason for this difference must be associated with the complexity of the physical mechanism of generation and propagation of waves on the water surface. In this work, a laboratory problem has been developed to measure the group velocity of circular waves traveling on the water surface. It uses a standard laboratory water tank equipped with a surface wave generator. The proposed experiment offers an opportunity for quantitative measurement of surface wave characteristics, a dispute of only qualitative observations of wave phenomena commonly found in current curricula, due to the introduction of two improvements. First, to produce the water waves’ rich in-contrast representations on a screen, the optimal generator amplitude is specially set for each experiment; and second, to measure the group wavelength, the device magnification is preliminary calculated based on the laws of geometric optics. The tests carried out have shown that the relative accuracy of these measurements is quite acceptable: within a few percent. The introduction of the problem of surface waves on water into the General Physics laboratory workshop for engineering specialties of technical universities will contribute to improving the quality of mastering the subject by students.
