Energy Coupling Mechanism of Electrodeless Plasma Thruster with Rotating Electric Field
Authors: Zhang Junjun , Sun Bin , Lu Chang , Xia Guangqing , Chen Chong 
Published: April 2023

The energy coupling process indicated by particle density, speed, current density, and power absorption in a thruster using a rotating electric field was simulated using a one dimension, three velocities electrostatic particle-in-cell (PIC) code under different external magnetic field strengths varying from 0 to 80 G. The longer interaction between electrons and the sheath layer due to the increased magnetic field results in a significant decrease in electron speed from [Formula: see text] at 0 G to [Formula: see text] at 80 G; a reduction in electron power absorption from [Formula: see text] at 0 G to [Formula: see text] at 80 G; and an increase in electron density, current density, and total current density about 69.48, 21.11, and 5.4%, respectively. While ions cannot respond to the changes in time because of their large mass. Three types of currents, namely, electron, ion, and displacement, are primarily present throughout the discharge process. Ion current is significantly less than the other two. The characteristics of plasma described exhibit a nonlinear change, dropping at first and then rising when the magnetic field is strengthened. The results have implications for both choosing the magnetic field for the thruster and thoroughly investigating the energy coupling inside the plasma.
Dynamics of a Wavy Axisymmetric Swimmer
Authors: Zhu Qiang 
Published: April 2023

A novel underwater locomotion method is proposed. In this method, the propulsion system is designed as an empty tube with two open ends. The sidewall of this tube is deformable so that the diameter of the tube varies both spatially and temporally, following a wavy pattern that travels from head to tail. By using a fluid dynamics model based on the axisymmetric Navier–Stokes equations, we numerically demonstrate that this design is able to generate thrust for self-propelled swimming. The sources of the thrust have been identified. Specifically, the physical mechanisms that assist with the swimming performance are 1) the momentum flux through the front and back openings; and 2) the normal stress at the front and back openings, most notably the suction force at the front opening due to negative pressure there. Moreover, a parametric study has been conducted to investigate the effect of geometric and kinematic parameters upon the performance of the system.

Authors: I. Hamodi Mohammad , K. Younis Mohammed 
Published: April 2023

In this work, Myrrh gum was used with sodium alginate (SA) to create novel Myrrh-Alginate beads composite. These beads were produced utilizing the ionotropic gelation technique. Methylene blue (MB) was employed as a drug model to evaluate the kinetics of drug release and the capacity of the synthesized beads to function as a drug delivery system. The molecular interaction between sodium alginate and myrrh was confirmed by FTIR spectroscopy. The physical characteristics of the Myrrh-Alginate beads, including drug content, particle size, thermal properties, equilibrium water content (EWC), swelling behavior, and equilibrium swelling ratio (ESR), were studied to establish the hydrogel's response type, as well as the releasing kinetics at 37°C and in Phosphate buffer solution (PBS) at pH = 6.8 and 10. All beads (loaded and unloaded) were analyzed by Differential scanning calorimetry, Scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD). The drug content percentages of the Myrrh-Alginate beads increased with a moderate fraction (5% ) of Myrrh but dropped with a higher Myrrh percentage. The Myrrh-Alginate beads absorbed more water and swelled more than the pure calcium alginate beads (S2) in pH 6.8 and 10 of (PBS). In a pH 6.8 of (PBS), the Myrrh-Alginate beads demonstrated a controlled and regulated style of releasing and demonstrated a high match with the Korsmeyer-Peppas model as they had the maximum values of the correlation factor (R2) in this model.

Purpose: The purpose of this study is to investigate the rewards that motivate employees in organisations in universities, and to identify the most effective types of rewards that can improve employee motivation and organisational success.
Methodology: This study utilizes a mixed-method approach, incorporating both qualitative and quantitative data collection methods. The target population for the study consisted of senior members, senior staff and junior staff of the University with a sample size of 196. A stratified random sampling method was used in selecting staff from the three categories. The qualitative data will be collected through in-depth interviews with employees from various positions in universities, while the quantitative data will be collected through a survey. The data was analysed descriptively using mean scores to identify the factors that influence the effectiveness of rewards in motivating employees.
Research Limitation: This study is limited by its sample size, which may not fully capture the diverse range of employees in universities. Additionally, the study's findings may be limited by the specific context in which the study is conducted.
Findings: An association between reward and productivity in the workplace was found in the study. Yet, the data also revealed that Cape Coast Technical University does not have a well-defined strategy for reward systems. As a result, workers felt that the institution did not treat them fairly.
Practical Implications: The study's findings are expected to have significant practical implications for universities, as they can use the insights gained from this study to develop more effective reward systems that can motivate their employees.
Social Implications: The social implications of this research are essential, as motivated employees are more likely to engage with students and provide better educational experiences, which can benefit society as a whole. By improving employee motivation and job satisfaction, universities can provide a better learning environment for their students and contribute to social welfare.
Originality/Value/ Novelty: The novelty of this study lies in its focus on rewards that motivate employees in organisations in the higher education sector. While previous studies have explored employee motivation in various sectors, this study's specific focus on universities adds to the existing body of knowledge.

Published: April 2023

Este trabalho avaliou retrospectivamente correções de imagens planares de pacientes já submetidos a tratamentos de neuroeixo, a fim de quantificar a magnitude dos erros de posicionamento e aplicá-los em diferentes técnicas de radioterapia em arco modulada volumetricamente (VMAT) para definir a que possui o menor impacto dosimétrico considerando estes erros, para implementação na prática clínica, que é objetivo deste estudo. Ao todo 219 imagens planares de 15 pacientes foram selecionadas para avaliação estatística de erros de posicionamento. Para os planejamentos, quatro pacientes pediátricos já tratados com técnica 3D conformacional foram selecionados. Para cada um, cinco planos de tratamento VMAT foram otimizados em duas técnicas: sobreposição com 3 cm, 6 cm e 9 cm de junção e gradiente com 6 cm e 9 cm e foram avaliados pelos índices: V100%, V95%, D98%, D2%, número de conformidade (CN) e índice de heterogeneidade (HI). Em cada plano, foram inseridos erros de posicionamento com a magnitude encontrada na análise retrospectiva das imagens, bem como avaliar a diferença na distribuição de dose quando considerado a mesa de tratamento. As imagens demonstraram deslocamentos médios entre 1 e 5 mm e em alguns casos chegando à 15 mm. Em relação à qualidade dos planejamentos, todos obtiveram resultados coerentes baseados nas métricas avaliadas sem diferenças significativas. Porém, a técnica de gradiente (9 cm de junção) reduziu o impacto dosimétrico em comparação às outras técnicas quando submetida aos erros de posicionamento. Por fim, ao considerar a mesa de tratamento nos planejamentos, foi encontrada uma redução de 10% no V100%. Os resultados mostraram que para implementação da técnica VMAT para neuroeixo recomenda-se realizar imagem de posicionamento diária para minimizar erros de posicionamento com magnitudes maiores que a média encontrada de 3 mm no sentido longitudinal, pois estes têm impacto significativo na distribuição de dose nos planejamentos modulados.
