Microwave welding is becoming more popular than conventional joining methods due to its advantages such as rapid and localised heating as well as applicable to components with complicated geometry. Previously reported susceptor, such as carbonaceous materials and conductive polymers, are toxic and the welding process involving these susceptors is time-consuming. Because of its exceptional microwave absorption and biocompatibility, silicon carbide nanowhiskers (SiCNWs) was employed as the microwave susceptor for microwave welding. Microwave welding in this study comprises of only three simple steps: SiCNWs suspension preparation, SiCNWs application and microwave heating. The weld strength of welded joint was then characterised using tensile test and energy dispersive x-ray spectroscopy equipped scanning electron microscopy (EDS-SEM) to study its mechanical properties and cross-section microstructure. The influence of microwave irradiation time was studied in this study, and it is found that the weld strength rose with the extension of microwave irradiation time, until a maximum weld strength of 1.61 MPa was achieved by 17 s welded joint. The development of SiCNWs reinforced PP nanocomposite welded joint layer is responsible for the enhanced weld strength. Prolonged heating duration may also result in flaws such as void formation at the welded joint, which subsequently lowered the weld strength to 0.60 MPa when the heating duration was extended to 20 s. In sum, a strengthen welded joint can be formed with rapid microwave heating under the proper control of heating duration.

Applications of nanotechnology are frequently used in the oil and gas sector. However, nanoparticles boost sand consolidation, lower interfacial tension between water and oil, and improve the mobility of trapped oil to increase crude oil recovery in enhanced petroleum recovery (EOR). Using aluminium PVP-coated low-porosity sand packing, the effects of nanoparticles on interfacial tension and water-oil surface contact were examined in this study. The horizontal column was filled with low-porosity sand, and the nanopowders were suspended in deionized water. The four distinct nanoparticle suspension pore volumes (PV) used in this experiment are 0.25, 0.5, 0.75, and 1.0 PV. At the column's output, the sample is then deposited, and the effluent is analysed and contrasted using IFT and viscosity with a solid viscometer. In this investigation, it was discovered that the water target zone had a very limited pore volume and only received 0.52 PV of injected nanoparticles. The better the oil can be extracted, the lower the viscosity and IFT value. The removal of the oil droplet and increased oil output for EOR could result from the transport of PVP nanoparticles coated with aluminium.

In this study, we prepared PSi using the laser-assisted electrochemical etching method and deposited Gallium nitride (GaN) on the PSi substrate using the pulsed laser technique at different pulsed laser wavelengths (1064, 532, and 355 nm). We investigated the optical, structural, topographical, and morphological properties of Gallium Nitride on the substrate PSi by various pulsed laser wavelengths. The X-Ray Diffraction (XRD) analysis revealed that gallium nitride on PSi was polycrystalline and hexagonal, cubic structural at 532 nm, with a high peak intensity and crystallite size at 2θ=36.96°and 57.80 related to (101) and (110) planes, respectively, while the c-GaN phase is observed at 2θ = 25.43 degrees and is reflected from the (200) plane. PL shows two emission peaks were observed for the GaN film (430,345,413 nm) and the PSi substrate (867,891,876 nm), and the energy gap increased as the wavelength decreased. The field emission scanning electron microscopy (FESEM) pictures revealed that the synthetic sample had an average size of 24.45, 23.91, and 21.30 nm, and the nanoparticles appeared spherical and similar to cauliflower. The atomic force microscopy (AFM) results showed that the average roughness was 7.62, 10.64, and 13.62 nm, respectively, and it was observed the root mean square increased as a result of the uniform distribution of high-quality crystals and the excellent quality of the crystal structure. The UV-Visible (UV) results showed that the transmission decreased with a decrease in wavelength, and the absorption was inversely proportional to the transmission.

Published: June 2024

This research paper explores the application of three laser systems, namely the Nd:YAG laser, fiber laser, and CO2 laser, for the micro/nano machining of silicon and quartz materials. The experimental results demonstrate the successful formation of stable silicon nanoparticles with reduced dimensions. Additionally, a quartz sheet was utilized to create a microlens array. The laser microprocessing technique was enhanced through the implementation of design of experiments (DOE) analysis. A Box-Behnken design (BBD) software was employed to conduct 17 tests, investigating the influence of laser parameters on the microprocessing outcomes. The COMSOL software was utilized for theoretical calculations to determine the distribution of surface temperatures and subsurface temperatures of silicon and quartz. The maximum temperatures achieved were approximately 5700 K for silicon and 2630 K for quartz. Numerical optimization using DOE software improved the production of silicon nanoparticles and quartz microlens, producing silicon nanoparticles wavelength peak and absorption peak values of 318.2 nm and 0.39, respectively. Additionally, quartz microlens numerical aperture and surface roughness improved to 0.494 and 4.64 nm, respectively. Due to the precise control offered by the laser micro/nano machining process, the findings of this study hold potential for diverse applications in optoelectronics and biological imaging that can leverage the unique characteristics of silicon nanoparticles and microlens arrays.

Published: June 2024

An effective strategy for ensuring the long-term availability of accessible resources involves the utilisation of green technology that integrates plentiful resources like cellulose. Cellulose has numerous qualitative advantages, such as being biodegradable, eco-friendly, biocompatible, and rich in hydroxyl (OH) groups. Consequently, cellulose supplies are plentiful and may be replenished in the environment. Thus, cellulose is commonly employed in the packaging, healthcare, and textile sectors. An investigation was conducted to examine the impact of the initial pH on the process of decolorizing methylene blue. The data reveals that a pH level of 44.4% exhibits worse performance compared to a higher pH level. Specifically, a pH level of 7 achieves a maximum decolouration of up to 98%. The study employed methylene blue (MB) as a model for the adsorption investigation. The results of this study suggest that cellulose nanofibrils (CNF) obtained from durian husk possess favourable characteristics as an adsorbent material or as a framework for the immobilisation of nanoparticles for use in nanoelectronics applications, which is a subject of interest.

Published: June 2024

This study reports on DEP-based simulation and experimental validation of polystyrene (PS) beads and fibroblast cells for primary skin cell migration for enhancing wound closure. MyDEP software was used to calculate the numerical simulation of the Clausius-Mossotti factor (CMF). In order to examine particle trajectories based on input frequencies, the finite element technique (FEM) is used. The trajectories of PS beads and fibroblast cells were experimentally assessed to verify the impact of frequency applied on the polarisation of PS beads and fibroblast cells. The outcome illustrated the potential of employing FDEP to move particles and cells to regions of high and low electric field. Fibroblast cells exhibit negative dielectrophoresis (NDEP) at a broad range of frequencies. Thus, FDEP can be utilised for frequency optimisation to enhance wound closure.

The operation of electronic devices can be disrupted by unwanted electromagnetic signals, affecting its operation. Deploying electromagnetic shielding is a viable solution to minimize the impact of electromagnetic interference (EMI). The conventional methods of electromagnetic shielding use metal gaskets to safeguard sensitive electronic components, which have drawbacks of cost and weight. Hence, electromagnetic shielding polymer can be an alternative to replace metal gaskets. This work investigates the effect of sodium ion (Na) addition to copper selenide/chitosan (CuSe/Ch) film for electromagnetic shielding applications. The shielding polymers were produced using solution casting methods, while the CuSe was synthesized using the chemical coprecipitation method. Impedance spectroscopy and two port waveguide methods were used to characterize the prepared polymer's electrical properties and shielding efficiency. The results indicate that Na incorporation in the CuSe/Ch film resulted in a 47 % decrease in bulk resistivity and increased DC conductivity from 6.07 × 10-6 S/cm to 3.69 × 10˗5 S/cm. The AC conductivity of films containing Na demonstrates a similar level of conductivity at lower frequencies, followed by a sharp increase at higher frequencies, indicating a more substantial influence of Na at higher frequencies. Higher absorption shielding efficiency (SEA) and lower reflection shielding efficiency (SER) were achieved by introducing Na into the CuSe chitosan film. The Na/CuSe/Ch film shows higher total shielding efficiency at an average of 20 dB, equivalent to 99 % of the EM power shield.

Published: June 2024

Poverty is now a multifaceted problem as it is related to the inability to access and participate in society economically, socially, culturally and politically. According to the Indonesian Waqf Agency (BWI), Indonesia, which has the world's largest Muslim population, has great potential for waqf money estimated at Rp. 1.4 trillion as of March 2022, this figure has increased when compared to the waqf money that has been collected in the 2018-2021 period of Rp. 855 billion. With a very large Muslim population and high potential for raising waqf funds, waqf in Indonesia has enormous potential as an instrument of development and poverty alleviation. Waqf can contribute to a country's economic development, It can reduce government spending, equalize income distribution, reduce poverty, and boost economic growth. Additionally, waqf has the potential to improve people's health. Essentially, the waqf should be productive as stated in the hadith. but the latest based on research results in the management process at PT Karya Mandiri Community (KMM) Parung has 2 main problems, namely human resource problems and institutional problems. The problem of human resources is divided into three aspects, namely, Nazhir's managerial ability is relatively low, Nazhir is less creative, and people's understanding is still traditional. While institutional problems, namely coordination between the PT KMM and the community is relatively low. This study focuses on problem solving analysis of productive waqf management issues carried out by PT KMM.

Cooxupé e o desafio da agregação de valor: oportunidades a partir da emergência climática
Authors: Pastre Rafael , Corrêa Bianca Muniz
Published: June 2024

A partir de modelos dinâmicos de evolução tecnológica, aplicados aos princípios fundamentais identificados pelos clássicos da Organização Industrial, foi possível identificar as vantagens competitivas e as estratégias adotadas pelas grandes corporações do agronegócio brasileiro em ascensão no exterior. No caso das empresas que conseguiram atender diretamente outros mercados, foi fundamental a estratégia de “nicho ambiental”, estabelecendo uma série de certificações e arranjos territoriais de uso e ocupação do solo no Brasil e validada por meio de parceria/aquisição de empresas no país alvo, contornando assim o protecionismo comercial aplicado aos produtos de origem agropecuária. Essas parcerias foram conquistadas a partir do poder de mercado das empresas brasileiras, tanto como compradoras (monopsônio regional de originação, oferta de crédito, orientação técnica, insumos e armazenagem), quanto como vendedoras (eficiência logística e ganhos de escala). Argumenta-se neste trabalho que a Cooxupé compartilha de todas essas vantagens, com um elemento adicional: Os mercados consumidores de café são muito mais exigentes e diversificados, o produto em si apresenta maior especificidade e variabilidade, além de que nossos concorrentes apresentam menor capacidade de enfrentar as novas demandas em um contexto de crescente preocupação com os efeitos do aquecimento global. Investiga-se sua oportunidade de verticalização e internacionalização comercial.

Qualitative research: Understanding its underlying philosophies
Authors: Asmawi Adelina , Alam Md. Saiful
Published: June 2024

In the realm of research, it is emphasized that research must be grounded in a clearly stated research philosophy and set out early in the research process. It is significant because research philosophy enables researchers to promote clarity and decisions about the research design and guide them in identifying a suitable design. Therefore, understanding the underlying philosophies of qualitative research is crucial for researchers, especially those who are just starting their journey in this field. This paper aims to provide beginning researchers with a basis for the development of key philosophical understandings related to qualitative research. A descriptive analysis of the philosophies of ontology and epistemology and the subsets of philosophies under these two umbrella terms is presented as an introduction to the philosophical foundation of qualitative research. The paper serves as a basis for novice researchers to distinctively identify the philosophical underpinnings of qualitative research and as a resource that enables and guides them towards designing and conducting qualitative studies.
Relativistic light clocks: Arbitrary orientation in uniform motion and hyperbolic motion analysis
Authors: Sfarti Adrian
Published: June 2024

In this paper, we address the general case of a light clock in uniform translational motion parallel to itself and perpendicular to its uniform velocity v, as well as the case of the light clock in relativistic hyperbolic motion. Neither case has been previously addressed in the specialized literature, which typically restricts itself to canonical orientations where the light clock moves parallel to either the vertical or horizontal axis with uniform velocity, without acceleration. Therefore, it becomes interesting to study the more general case where the clock has an arbitrary orientation and/or is accelerated. Our paper is divided into two main sections. The first section deals with the light clock moving with constant velocity, oriented at an arbitrary angle with respect to the x-axis. We prove that the moving clock exhibits a standard time dilation, identical to that of a light clock moving in a canonical orientation. The second section deals with the light clock moving with constant acceleration, i.e., in hyperbolic motion. For the light clock in hyperbolic motion, we derive the period as measured from the perspective of an inertial frame and draw parallels with the case of uniform motion, outlining a term that is similar (but not identical) to the γ factor of uniform motion. We also point out that this factor depends not only on acceleration but also on the height of the light clock. This dependency on the dimension of the light clock distinguishes the accelerated case from the case of uniform motion. The first three sections deal with the theoretical aspects of light (optical) clocks, while the fourth section addresses the experimental implementations of optical clocks.

Family-centered care is crucial for parent-infant bonding and collaborative healthcare in neonatal intensive care units. COVID-19 visitation restrictions have hindered this care’s effectiveness and posed challenges in Thai units. This study, conducted in a southern Thailand hospital, explored nurses’ and parents’ perspectives on implementing family-centered care during restricted visitation policies, providing globally applicable insights. An exploratory-descriptive qualitative approach was used, involving semi-structuredinterviews with ten nurses and ten parents to explore their nuanced perspectives from June to August 2023. The interviews were conducted face-to-face, individually, using a semi-structured interview guide, and the transcripts were analyzed using thematicanalysis to identify significant themes. Findings from this study comprised five themes: 1) Having a mindset to involve parents in care, 2) Parents receiving psychological support, 3) Challenges of communication, 4) Negative impact of restricted visiting times, and 5) Accommodating flexible visiting hours in exceptional circumstances. Providing the best possible care for infants requires an adaptable and flexible approach to meet each family’s unique needs. Additionally, healthcare providers need to explore how they can implementfamily-centered care effectively during visiting restrictions in the NICU in different contexts. Further research is necessary to investigate the practical implementation of this by nurses and how hospital administrators can support it in Thai neonatal intensive care units under policies restricting family visits.
Simulation and analysis of optimal energy-saving mode in microfield of underground rail transit
Authors: Wu Shuang , Chen Yunlan , Lin Xin
Published: June 2024

Underground rail transit has become one of the most popular transportation modes because of its advantages such as fast running speed, large passenger flow and punctuality. This mode of transportation can alleviate urban traffic congestion to a certain extent, so underground rail transit has been vigorously developed, and the number of rail lines has increased exponentially. However, with the continuous development of underground rail transit, the energy consumption of train operation is also increasing, resulting in a waste of energy. To solve this problem, this paper proposes to improve the energy-saving technology of train operation by using train autopilot control strategy. Firstly, a train operation optimization model considering train position and speed limit is established by using automatic train driving strategy, and the nonlinear problem of the optimization model is solved by genetic algorithm. The micro-field theory is introduced into the control strategy of automatic train driving, and the energy-saving model of underground rail transit is established. The energy consumption is optimized from three aspects: train energy-saving technology, line planning and overall operation planning of rail transit. The simulation results show that the average impact rate and energy consumption of trains under the proposed energy-saving model are significantly reduced compared with the other two groups of trains, and the average impact rate and energy consumption are significantly reduced compared with the other two groups of trains. The running time and energy consumption of the energy-saving model are lower than those of the experimental group. To sum up, the energy-saving model of underground rail transit proposed in this paper not only reduces the operating energy consumption, but also improves the passenger comfort, which can provide low-cost energy-saving technology for underground transportation field, and has positive significance for urban low-carbon development.
Assessment of traffic sign retroreflectivity for autonomous vehicles: a comparison between handheld retroreflectometer and LiDAR data
Authors: Aldoski Ziyad Nayef , Koren Csaba
Published: June 2024

This study investigates the critical role of retroreflectivity in traffic signs, particularly in the context of autonomous vehicles (AVs), where accurate detection is paramount for road safety. Retroreflectivity, influencing visibility and legibility, is essential for ensuring safe road conditions. The study aims to assess traffic sign retroreflectivity using handheld retroreflectometers and LiDAR data, offering a comprehensive comparison of results with a specific focus on the RA1 and RA2 traffic sign classes. In a real-world setting, an AV equipped with LiDAR sensors, GPS units, and a stereo camera collects data on traffic signs, including point cloud attributes such as intensity and density. Simultaneously, a handheld retroreflectometer measures retroreflectivity coefficients from identified traffic signs. While retroreflectometers provide precision, they face limitations regarding time-consuming measurements and handling large or elevated signs. In contrast, LiDAR systems efficiently evaluate retroreflective features for numerous signs without such constraints. Despite both methods consistently yielding accurate retroreflectivity, the study reveals a limited correlation between LiDAR point cloud data and handheld retroreflectivity coefficients. The implications of these findings are significant, particularly in the selection and maintenance of retroreflective materials in traffic signs, with direct repercussions on overall road safety. The results offer valuable insights into leveraging LiDAR technology to enhance AVs' detection capabilities. Recommendations for further research include exploring factors influencing LiDAR intensity, establishing a more accurate relationship between intensity and retroreflectivity, correcting the point cloud during intensity calibration, and testing empirical prediction models with a larger sample size. These endeavors aim to generate a robust regression graph and determine correlation coefficients, providing a more nuanced understanding of the intricate relationship between LiDAR data and handheld retroreflectivity coefficients in the context of traffic sign assessment.
Methodology of evaluating finished goods warehouse performance through lean methods
Authors: Michlowicz Edward
Published: June 2024

This paper considers the problem of evaluating the effectiveness of the finished goods warehouse of a manufacturing company, in which a modified TPM method - Total Productive Management (TPM2) - was applied to improve productivity. A multi-stage methodology was proposed, including a decision to modify the system, determination of the scope of changes, monitoring the results obtained and a multi-criteria evaluation of the changes made. The decision to make modifications to the existing system was motivated by the lower-than-expected quality of customer service (frequent delivery delays). With regard to the transport department, lean flow pillar activities were focused on analysing losses (muda) in warehouse processes (product loading and package unloading). The purpose of these activities was to minimise interruptions in warehouse processes (product loading and package unloading). "The steps for solving the problem" methodology based on Deming's PDCA cycle was used to solve the problem. The analysis covered, among other things, the information flow processes between production planning and the customer service department, the planning processes of the dispatcher, the efficiency of the loading processes, and the causes of interruptions in warehouse operations. The analyses employed the chronometry of selected works, the 5W + 1H method and the Pareto method. By using the 5S method and some characteristics of the SMED method, the organisation of loading work was decisively changed (shunting yard changes, appropriate buffers for transport equipment). The changes introduced in the system were monitored for several months. Appropriately defined OEE indicators were used to assess the behaviour of the system after the changes. The indicators consider the use of available warehouse time, the efficiency of the loading process and the quality of the tasks performed. The results that can be achieved are presented using the specific example of the finished goods warehouse of a manufacturing company in the FMCG sector.
