Authors: AlSaba Eslam
Published: August 2024

Aim: this paper discusses a VLC system with a simple and cheap model design for transmitting audio and digital signals using LiFi technology to illustrate Li-Fi technology, which has become the future of wireless communications.

Methods: Visible light communication (VLC) is wireless communication using visible light as a means of transmitting information. Light is an electromagnetic wave with a wavelength ranging from 375 Nm to 780 Nm or a frequency spectrum ranging from 400 Hz to 800 Hz. Thus, it has become an important pillar and requirement in the development of wireless communications, and therefore, it has become one of the foundations of 5G communications. In the VLC system, the light-emitting diode (LED) is used as a transceiver to send and receive data, not to mention as lighting. The LED has a longer lifespan, low power consumption, a high tolerance to moisture, and a smaller size. So, it is more environmentally friendly and does not cause any harm to living organisms. And as the LED is used for lighting, it can also be used for communication. Thus, they are growing rapidly due to low energy consumption and high efficiency.

Results: The prototype was successful in achieving the aim of this study. As the VLC audio transceiver using an optical transceiver has been designed to demonstrate the functioning of the VLC system. The analysis of the designed system and output is presented. The designed system by using a microcontroller overcomes the critical problem with occurrence due to the intensity of the background light.

Conclusion: The field of data transmission needs rapid and effective development due to the large amount of data required to be transferred quickly to meet technological developments, especially in communications and data transmission applications. This will not be achieved using current technologies, but they must be developed, such as using the light field. Therefore, Li-Fi has become a pillar of harmless development and rapid and effective progress. Light also has a wide spectrum, which allows different uses in the transmission, reception, and monitoring of various types of data, as well as in the generation, production, and transmission of energy. Light is also capable of transmitting data at an incredible speed compared to other media used for this purpose, such as metals and electromagnetic fields. Thus, it became the recommended light field.

Authors: Okina Maurice
Published: August 2024

Aim: This paper reviews the prevalence of generative artificial intelligence (GAI), analyses the ethics of GAI in academic writing, and evaluates ethical implications on academic integrity and quality lastly, we identify and propose solutions to the challenges identified.
Method: A descriptive review which is a fact-finding mission that exposes or determines the interpretable pattern shaping a given research topic was used. The existing documents on the subject matter were searched, screened, classified, and reviewed through a literature review. Study questions were defined; relevant studies were identified and selected. The data about the studies were charted; collated and summarized lastly the results were reported.
Results: The pervasiveness of AI has been identified in the areas of grammar and formatting, plagiarism detection, content generation, and research assistance. In the purview of ethical concerns, plagiarism is more conspicuous and incidentally affects the severity of the other ethical concerns in one way or another. Authorship has been acknowledged to connote responsibility and thus arguments about authorship and co-authorship need consent to secure accountability. The paper also explored transparency and bias in using AI in academic writing. The acquisition of data used in training and how training is done; the black box concepts that hold the transparency element and how to remedy its effects. Further, moral, legal, and fair uses were reviewed, converging at a legal understanding. Equality in the academic journey exposed equity concerns including access and affordance, legal constraints, and bans in some parts of the world.
Conclusion: AI can assist in grammar and formatting, plagiarism detection, content generation and research assistance. However, ethical, legal as well as moral framework guiding application of GAI is necessary to enable proper use that is acceptable and beneficial to the society in general. Disclosure encourages ethical principles. Openness, honesty transparency, etc. can be cultivated when sources used in academic writing are declared. The value of research is realized when it is published and it can be reproducible. This can happen if it is credible and authentic. The synthesis required for foundational literature to anchor the research should be judged by a human author and not a machine to aid originality.

The Potential of Artificial Intelligence for Personalized Surgical Planning: A Letter to the Editor
Authors: Eissa Mostafa
Published: August 2024

This letter explores the potential of artificial intelligence (AI) in personalized surgical planning. AI offers a powerful toolkit to create patient-specific roadmaps, enhancing preoperative analysis, decision-making, and surgical simulation. Traditional surgical planning relies on subjective interpretations of medical images and can be impacted by surgeon fatigue or anatomical variations. AI-powered analysis with deep learning algorithms can dissect complex images, identifying subtle anatomical variations and enabling more precise surgical targeting. Predictive analytics, leveraging vast surgical datasets, anticipate potential intraoperative risks, allowing surgeons to proactively prepare. Additionally, AI facilitates personalized surgical simulations using 3D virtual models, optimizing surgical strategies and minimizing tissue damage. Integration of AI into surgical planning promises significant improvements in patient outcomes, including increased precision, improved efficiency with shorter operating times, and enhanced patient safety through risk identification. However, challenges remain, including data quality and mitigating bias in AI algorithms, ethical considerations regarding patient privacy and surgeon autonomy, and the need for robust regulatory frameworks. The future of AI in surgery hinges on continued research and collaboration. Standardized data collection, development of explainable AI models, and rigorous clinical trials are crucial for unlocking AI's full potential. This surgeon-AI partnership has the potential to revolutionize surgical care, offering a personalized approach that optimizes outcomes for each patient.

Authors: Jadhav Sahil Mahadev , Sanjay Mahandule Kaustubh , Garje Vaibhav Laxman , Modak Prof . Dr.G.S
Published: August 2024

The oil skimmer serves to remove the floating oil from the fluid. The oil sits on the water since it has less density than water. Water molecules are more attracted to each other than that of oil since they don’t mix with each other. In this case, the skimming medium is a belt and a metal disc. The skimming medium passes over the surface of the water, bringing out oil with a small bit of water. The main purpose of this fabricated skimmer is to purify the water from various dirt oils. In comparison to more expensive treatments such as membrane filters and chemical treatments, the skimmer is more cost effective efficient as well and straightforward in construction. The oil is removed from the metal disc and belt through wiping blades. Over the last 40 years, there have been hundreds of big oil spills all over the world, most of them were caused by ship collisions. There are numerous strategies for dealing with an oil leak accident, the most successful of which is to use a mechanical oil skimmer with a disc plate. The efficacy of the oil skimmer in dealing with oil spills is determined by a number of elements, including the depth of the disk submerged or the disk surface area dipped into the oil spill, the area of the wiper sweep, the thickness of the oil on the disk surface, and the disk rotation speed. The findings of a small size experiment with a mechanical oil skimmer are presented in this article. Diesel engine oil was utilized in the oil samples.

Authors: Kumar Manoj , Kumar Singh Dr. Ashutosh , Kumar Dr. Chandan , Chauhan Sanjay
Published: August 2024

Underwater wireless optical communication (UWOC) has attracted increasing interest in various underwater activities because of its order-of-magnitude higher bandwidth compared to acoustic and radio- frequency technologies. Practical pre-aligned UWOC links were constructed for physical layer evaluation, which verified that UWOC systems can operate at tens of gigabits per second or close to a hundred meters of distance. This holds promise for realizing a globally connected Internet of Underwater Things (IoUT). However, due to the fundamental complexity of the ocean water environment, there are considerable practical challenges in establishing reliable UWOC links. Thus, in addition to providing an exhaustive overview of recent advances in UWOC, this paper addresses various underwater challenges and offers insights into the solutions. In particular, oceanic turbulence, which induces scintillation and misalignment in underwater links, is one of the key factors in degrading UWOC performance. Novel solutions are proposed to ease the requirements on pointing, acquisition, and tracking (PAT) for establishing robustness in UWOC links. The solutions include light-scattering-based non-line-of-sight (NLOS) communication modality as well as PAT-relieving scintillating-fiber-based photoreceiver and large- photovoltaic cells as the optical signal detectors. Naturally, the dual-function photovoltaic–photodetector device readily offers a means of energy harvesting for powering up the future IoUT sensors. Key Words Underwater Wireless Optical Communications (UWOCs), Link Configuration, feasibility analysis, link budget and communication range.

Student Perceptions of Undergraduate Chemistry Laboratory Shaped by the COVID-19 Pandemic
Authors: Lyubartseva Ganna
Published: August 2024

Laboratory activities are essential and important components of learning chemistry at the undergraduate level. The COVID-19 pandemic led to disruption of traditional modes of teaching and learning over the whole education spectrum including laboratory courses in chemistry. Although unfortunate, the COVID-19 lockdown period and following years challenged well accepted norms leading to new opportunities for higher education. The purpose of this work is to synthesize useful lessons from student experiences during COVID-19 pandemic and post-pandemic era aiming for improved future chemistry laboratories at the college and university level. Previously published studies addressed advantages and disadvantages of face-to-face vs. remote and online teaching of chemistry laboratory courses. However, there are only a few student-centered studies which analyze students’ perceptions of undergraduate chemistry laboratories in the post-pandemic era. Although the study was conducted at the university in the United States, we believe the lessons learned could be used globally. The present study contributes to the existing body of knowledge in this field of research. It is unique because surveyed students experienced different modalities of the laboratory and were given an opportunity to compare both modalities side by side. Therefore, student experiences provide stronger foundations of their preferences and perceptions described in this work. Based on our findings, it appears that post-pandemic undergraduate students taking a non-major course prefer hands-on experiments and a hybrid modality of chemistry laboratory.

Authors: ROSENBERGER Philipp , GRITSCH Christoph
Published: August 2024

Project management models and guidelines focus on standardizing and describing which kind of tasks project managers need to perform and how to perform these tasks. While these frameworks detail such activities, they do not cover how much project managers should perform different tasks depending on their particular project phase and other factors like project size and experience of the team. This article is based on the concept of multivariate regression and optimization being used to improve Project Process Relevance Factors as described in the Ph.D. thesis "Optimized Tailoring of Agile Project Management Frameworks - From Combining Scrum and PMI towards Multivariate Optimization" by Philipp Rosenberger (Rosenberger, 2022). The doctoral dissertation provided the data and scientific approach that was utilized as well in this article. The purpose of the research is to examine how project experience affects the project management activities that must be completed throughout the execution phase in order to optimize the health and success of a project. The data analysis indicated significant similarities in the distribution of emphasize between novice and skilled project management practitioners. After optimizing the distributions of relevance, the results indicate that experienced project managers need to concentrate more on supporting the project process as such. This involves conducting risk responses and overseeing stakeholder participation. In contrast, novice project managers should to focus on managing specific outcome-related project tasks.
Synchronized entropy of totally synchronizing generated systems
Authors: Shahamat Manouchehr
Published: August 2024

We introduce the notion of a minimal generator \(G\) for a coded system \(X\); that is a generator \(G\) for \(X\) such that whenever \(u \in G\), then \(u \not \in W \big(\overline{} \big)\). An \(X\) possessing such a \(G\) is called a minimally generated system. We introduce a class of minimally generated totally coded shift spaces generated by certain synchronizing blocks. For such shift spaces \(X\) we are able to show that if \(x \in X\), then there is unique \(\{\ldots , v_{-1}, v_0, v_1, v_2, \ldots \} \subset G\) such that \(x = v_{-1}v_0v_1v_2\). A carefully constructed example also shows that the converse of this statement is not necessarily true.
The derived shift space \((\partial (X))\) of \(X\) plays an important role in the dynamics of the system. We characterize the derived shift space and use it to give a new shorter proof for computing synchronized entropy \(h_{syn}(X)\).

In this paper we investigate the uniqueness problem of entire function \(f\) and its linear differential polynomial\begin{equation*}a_{k}\left( z\right) f^{\left( k\right) }+a_{k-1}\left( z\right) f^{\left(k-1\right) }+\cdots+a_{1}\left( z\right) f'\end{equation*}sharing an entire function \(a\equiv a\left( z\right)\) counting multiplicities(CM) with\begin{equation*}\sigma \left( a\right) <\sigma \left( f\right)\end{equation*}under some restrictions imposed on the coefficients \(a_{j}\left( z\right) \left( {j=1,2,\dots,k}\right)\). Our result improves and generalizes some earlier results.

Osteoarthritis of the hip is a prevalent degenerative joint disease characterized by various genetic and environmental influences. This review emphasizes the contributions of key genetic mechanisms, particularly the COL2A1 and GDF5 genes, to cartilage damage and the pathogenesis of osteoarthritis. Genetic mutations, polymorphisms, and variations in these genes are linked to heightened risks and more severe clinical presentations of osteoarthritis, especially in patients following COVID-19. Furthermore, additional genes involved in inflammatory responses and cartilage metabolism also play a crucial role in disease development. The insights gained from genetic research may lead to innovative approaches to early diagnosis, personalized treatment plans, and improved management strategies for osteoarthritis. Future studies utilizing larger patient cohorts and advanced genetic analysis methods are essential to confirm these findings and enhance understanding of osteoarthritis, ultimately improving preventive and therapeutic interventions.

Background: Injury is one of the most common reasons for hospitalization of young people, with millions worldwide sustaining a traumatic injury requiring hospitalisation each year. Aim of the study: To study the pattern and quantum of traumatic brain injury managed in our institution. Patients and Methods: This is a retrospective review of all children aged 0 to 12 years treated for TBI at the UCTH between January, 2016 and December, 2020. Clinico-demographic details of the patients were obtained and analysed. Results: The mean age of the patients was 58.61±29.36 with male to female ratio of 1.4 to 1.The mean Glasgow Coma Score was 8.63 ±3. Falls, mostly from domestic accident and pedestrian traffic injuries were the most frequent aetiologies (39.77% and 34.09% respectively). Extra-axial bleed was found in 29.55% (26/88) of the patients while cerebral contusion was found in 31.82% (28/88) of the patients. Scalp injury occurred in 27.27% (24/88) patients while 17.05% (15/88) had skull fracture. Operative treatment was carried out in 20.45% of the patients. More than eighteen percent {18.18% (16/88)} had blood transfusion in the course of treatment. Conclusion: The toddlers and pre-school age children had the highest frequency of traumatic brain injury in this study accounting for 56.82% (50/88) of the total number of patients. Severe traumatic brain injury was the most common type of head injury in this study with a frequency of 44.32%. The recovery rate was high with 98.86% of the patients recovering with a GCS of 14/15 to 15/15 at the time of discharge from the hospital. Fall mostly from domestic accident was the most common aetiology and responsible for 39.77% of the patients studied.

Background and objective: To investigate the acute toxicity of Produced Formation Water on the oxidative stress and biochemical parameters of Tilapia guineensis under semi-static conditions at a concentration of 100 to 700ml for 96 hours. Materials and Methods: The juvenile of Tilapia guineensis were exposed to different concentration of Produced Water, and their LC50 value of 223.10ml was calculated after 96-hour exposure period. The antioxidant enzyme profile investigated include: glutathione reductase, superoxide dismutase, glutathione peroxidase and catalase. Stress biomarkers such as protein, alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST) were also determined at 24-hour, 48-hour, 72-hour and 96-hour exposure periods. Results: Lipid peroxidation (MDA) showed significant (p<0.05) decreases in higher concentration and exposure period of 72-hour and 96-hour. Significant concentration-dependent increases (p<0.05) were observed in the liver function enzymes, Superoxide dismutase, Catalase and glutathione reductase when compared to the control. Glutathione peroxidase when compared to the control decreased significantly (p<0.05) in higher concentrations and 48 - 96hour. Conclusion: The changes in the hepatic antioxidant enzyme activities and serum metabolites were evident of oxidative damage induced by Produced Formation Water. This showed that the treated Produced water is toxic to the fish and regulatory agency in oil and gas industry should improve their effort to ensure they are treated efficiently before discharged into the aquatic ecosystems to prevent potential toxicity associated with it.

Effect of Instrumental Music Therapy on Preoperative Anxiety Levels in Patients at Imanuel Hospital Bandar Lampung
Authors: Novian Andreas Andri , Anita Fitri , Yuliana Dewi
Published: August 2024

Anxiety is an uncomfortable feeling of powerlessness caused by unpleasant new experiences, resulting in tension, agtation, and loss of control due to subjective judgment. Anxiety often occurs in patients undergoing surgical procedures. The prevalence of anxiety in Indonesia in preoperative patients ranges from 45% to 75%. This piroves that the majority of paitents undergoing surgery expierience anxiety. One way to alleviate anxiety is through relaxation distraction techniques, such as instrumental usic therapy. The effects of instrumental music therapy include reducing stress and anxiety, as well as improving concentration. The statistical test results obtained a significance value oif 0.00 < p 0.05, indicating a significiant difference in the level of preoperative patient anxiety before and after being given instrumental music therapy intervention. Thus, it can be concluded that instrumental music therapy affects the level of preoperative patient anxiety at Imanuel Hospital Bandar Lampung. Suggestions for Imanuel Hospital are to implement instrumental music therapy as one of the nursing interventions to reduce anxiety in preoperative patients. With the provision of instrumental music therapy, it is hoped that patients undergoing surgery will feel calmer, allowing the surgical procedure to proceed simoothly and effectively.
