Authors: Sandeep V. Raut Aditya R. Wankhade, Nilesh A. Jadhav, Chetan E. Kolambe,
Published: August 2023

The phrase “Levitation” refers to a class of technologies that uses magnetic levitation to force wind turbines with magnets, which otherwise propel   with axles and bearings. Maglev (derived from magnetic levitation) uses magnetic levitation to propel wind turbine for the generation of electricity. The present scenario indicates that the demand for electricity is increasing day by day and to meet it many research are going on. Electricity generation through renewable energy sources has gained attention in the last few decades due to depleting conventional energy sources and may help to reduce reliance on fossil fuels. One of the rapid growing renewable energy sources in the world is wind energy source. With the use of magnetic levitation the efficiency of the wind turbine can be increased and losses minimized. It also increases the life span of the generator. Magnetic Suspension Wind Power Generators, represent a very promising future for wind power generation.

Authors: Rojano-Alvarado Yolmis , Contreras-Cuentas Margarita , Cardona-Arbelaez Diego
Published: August 2023

International migration continues to be one of the opportunities that millions of people in the world consider to improve their living conditions and, as a social phenomenon it continues to grow. This article explores the experience of Venezuelan migrants who carry out the activity of “auto glass cleaners” as a livelihood at stoplights and road junctions of the Special, Tourist and Cultural District of Riohacha in La Guajira, Colombia. We base the research on the ethnographic observations and the application of qualitative interviews to 12 young Venezuelan migrants; then, through an ethnographic analysis and sustained in the participant observation and photographic records, we studied empirically this socioeconomic phenomenon. The findings focus the activity on three characteristic levels: difficulties, survival and revival, defined from external and typical factors of the window cleaners who, in the dynamics of work, represent an informal economic system sustained in their day-to-day needs.

Published: August 2023

The trend towards a society differentiated by an economic and social structure whose wealth generation system is based on knowledge marks the break with the so-called industrial society. Organizations operate in an environment of change and uncertainty and are forced to discover new ways of doing administrative management. Therefore, this article analyzes the role of knowledge in organizations and its management as a strategy for achieving competitive advantage. This work has a reflective nature and was built from the literature review available in academia. The results show that efficient administration of knowledge involves the combination of four factors: human capital, communication, technology, and innovation, and generates high levels of organizational growth, continuous improvement, competitive advantage, and survival in the market.

An application of ontology driven machine learning model challenges for the classification of social media data: a systematic literature review
Authors: Kero Admas A. , Demissie Dawit H. , Tune Kula K.
Published: August 2023

This systematic literature review aimed to explore the challenges and limitations of applying ontology driven machine learning models to the classification of social media data. Social media platforms generate a vast amount of data that requires automated and reliable classification to facilitate analysis and decision-making. Ontology driven machine learning models offer a promising approach to address this need by harnessing the power of both ontologies and machine learning algorithms to improve accuracy and efficiency. However, the application of such models to social media data classification poses unique challenges due to the complex and dynamic nature of social media data. To address this research gap, a systematic literature search was conducted, and 20 studies were included in the review. The findings of this review suggest that ontology driven machine learning models offer a promising approach to address the challenges of social media data classification. However, the existing literature highlights several challenges that need to be addressed, such as ontology development, feature selection, and model validation. Overall, the review provides insights into the current state of research on ontology driven machine learning models for social media data classification, identifies research gaps, and suggests directions for future investigation.
Sirturo- a diarylquinoline (bedaquiline): a novel approach for the treatment of MDR-TB and pre-XDR TB
Authors: Uradi Saraswathi
Published: August 2023

Sirturo (bedaquiline fumarate) is a new antitubercular class of medicine, lately, FDA, approved and indicated for use as a part of an appropriate applicable combination regimen along with other antitubercular medicines (i. e.; 2nd line anti-TB agents) for pulmonary multidrug-resistant tuberculosis (MDR TB) in grown up with age 12 years to less than 18 years of age and weighing at least 30 kg when an alternative treatment regimen cannot be considered for the reasons of resistance or tolerability. Bedaquiline, an enantiomer chemically belongs to the diarylquinoline (DAR) compound, which is nearly related to fluoroquinolones and chloroquine with differences in their side-chain moiety. Amongst all anti-TB medicines that have been approved, bedaquiline has a unique mechanism, which targets energy metabolism i. e.; adenosine triphosphate of mycobacteria, and eventually leads to bacterial cell lysis. ATP is an essential energy-producing molecule required for metabolic actions and survival of Mycobacteria and also for many other cells. Mycobacteria generally invade into well-encapsulated lung cavities and endosomes of macrophages, which can survive even under low oxygen levels leading to resistance against standard TB drugs. Bedaquiline has a spectrum of activity against drug-susceptible TB and MDR TB. Many clinical trials and studies demonstrated that bedaquiline is a crucial component of a combination regimen for multidrug-resistant TB.
Measuring cochlear duct length in North Indian population: a detailed study
Authors: Sumit Maheshwari  , Sainy Neeraj , Gupta Neha , Mehrotra Rohit , Mehrotra Monika , Mehrotra Ujjwal
Published: August 2023

Background: The cochlea is a shell-like structure of the inner ear which is comprised of two canals (the Scala vestibule and the Scala tympani) and the Organ of Corti. Cochlear duct length is defined as the length of the scala media as measured from the middle of the round window to the helicotrema. Preoperative measurement of CDL is significantly important if the desired intracochlear electrode array placement is required.
Methods: This retrospective study was done in Mehrotra ENT Hospital, Kanpur, India, which is a tertiary care hospital and referral centre for cochlear implants. We included 800 patients (400 males and 400 females) in the study with bilateral hearing loss who were evaluated for cochlear implantation. HRCT temporal bone of these patients were analyzed and a variable A was measured.
Results: Our study included 800 patients, Mean of distance A value for male children is 7.94mm (range 7.0-9.2mm). Mean of distance A value for female children is 7.72mm (range 6.95-8.8mm). So the overall average is 7.83mm. We calculated cochlear duct length using the formula, CDL=4.16A-3.98. The mean cochlear duct length was 28.6mm with a range from 24.9-34.3mm.
Conclusions: Our study is one of the most detailed large (800 cases) study of cochlear duct length in the North Indian population. Our results suggest that an average smaller cochlear duct length in our geographical area is a significant finding in the understanding of cochlear anatomy and physiology. It will have great importance on the insertion depth in cochlear implantation.

Published: August 2023

Nasal lobular capillary hemangiomas are rare and benign tumors of the paranasal sinuses. The aim is to study a case of nasal lobular capillary hemangioma. Here, a case of a 29-year-old male patient who presented to ear, nose and throat outpatient department (ENT OPD) with complaints of multiple episodes of epistaxis and left nasal obstruction for the past year. After proper radiological, cytological and hematological assessment, an excision biopsy from the mass of the left nasal cavity was performed which was suggestive of lobular capillary hemangioma. The patient has been operated on via lateral rhinotomy approach and nasal mass was found to be originated from the anterior ethmoidal artery, removed piecemeal and complete excision was done. Nasal lobular capillary hemangioma is quite a rare lesion of unknown etiology especially when it occurs in the nasal cavity. It should always be considered in the differential diagnosis of vascular lesions within the nasal cavity. Complete excision of the mass with a lateral rhinotomy approach gives an excellent outcome.

The monograph deals with the issue of youth volunteering in a public high school. In the literature, although much has been written about volunteering, there is little research on school volunteering, especially its educational significance. It seems legitimate to study the attitudes of teachers and young people already on the threshold of adulthood toward volunteering. In Poland, participation in volunteering is at a low level. Therefore, it seems important to activate young people and strengthen pro-social attitudes in them. One of the benefits of such activity is the formation of social, civic and educational competencies of youth in action. The present study is an attempt at both theoretical considerations on the issue of volunteering, as well as a study of volunteering in general high schools in Szczecin. This monograph wanted to show that volunteering can support education, through learning in its various aspects, enhancing individual, social and professional development. Volunteering is a form of non-formal and lifelong education. Thus, an attempt was made to study volunteering in high schools. This issue seems extremely relevant, important, timely and worthy of in-depth analysis and reflection.

Correlation between the Symptoms of Major Depression during Pregnancy, Fetal Indicators and Delivery Complications
Authors: Agani Shpresa , Agani Nysret
Published: August 2023

Introduction: Studies have shown a high prevalence rate of the symptoms of major depression in the general population of women on Kosovo (43.18%), therefore research on the impact of depression during pregnancy on the intrauterine fetal development and complications during and after delivery in the population of women on Kosovo at reproductive age has scientific and professional rationale.
Objective: The purpose of the study is to research correlation of major depression symptoms during pregnancy with the indicators of intrauterine fetal development and complications during delivery.
Method: The research is prospective randomized and after fulfilling the selective criteria included three hundred pregnant women in the second trimester and at the beginning of the third trimester of pregnancy in the general population of women on Kosovo. Scale of the major depression symptoms was determined with the Hopkins Symptom Check List (HSCL-25). Statistical package for results analysis included software SPSS 12, ANOVA analyses, frequencies, Chi square test, and linear regression analysis.
Results: Significant correlation was proven between the symptoms of major depression during early and mid-pregnancy with: uterine contractions at the beginning of labor, perineal lacerations during delivery, tachycardia in the newborn baby, duration of newborn’s stay in the neonatal intensive care unit, the woman's duration of hospital stay in the department before and after delivery, and the delayed start of breastfeeding. Findings proved that there is no significant correlation between the emotional state of pregnant women and the slowing down of the intrauterine fetal development.
Discussion: Based on the study results and the data from the literature, these clinical correlations are a result of interaction between the major depression during pregnancy with neuroendocrine trajectories of pregnancy, fetus and placental functions.
Conclusion: Major depression during early and mid-term pregnancy may have impact on specific clinical parameters of the childbirth and newborn baby. The obtained results suggest the need for systematic mental health support of the woman during pregnancy.
Effective Succession Planning Practices Pose Challenges within African Establishments
Authors: Omambia Matagi Salim
Published: August 2023

There has been a growing demand for equilibrium in the worldwide high dependency ratio. The overall increase in lifespan with a corresponding decrease in fertility rates has resulted in a populace that is predominantly composed of senior citizens. At times, institutions tend to prioritize their own organizational requirements above the needs and interests of their individual employees. Such an approach often results in the exclusion of employees and their willingness to transfer, assume new positions, or participate in developmental activities being overlooked. This can lead to demotivation among employees and ultimately impact the overall performance of the institution. Succession planning must have the full cooperation of all involved parties to succeed. If organizations want to be successful, particularly in realizing their vision-mission, it is important to find the right people who will be part of their journey toward greatness. Achieving success today requires both hard work and smart work, not just one or the other. In our interconnected world, organizations are no longer isolated entities. To ensure continuity, succession planning is a deliberate process that prepares employees for promotion within the organization. This tool helps management identify critical roles and individuals possessing the necessary skills. Typically, employees are hired based on their knowledge, rather than their ability to perform tasks. Passing on organizational knowledge to potential successors can significantly reduce the amount of time needed to adapt to a new position.

Authors: Faisal Faisal , Rochmah Nur , Faizi Muhammad , Novina Novina , Nuraeni Erni
Published: August 2023

BACKGROUND: Type 1 diabetes (T1D) mostly occurs due to the destruction of pancreatic beta cells due to autoimmune processes. Diagnosis of T1D can be established by examining the c-peptide levels and the markers of pancreatic autoantibodies, including glutamic acid decarboxylase 65 autoantibodies (GAD-65). However, the association between c-peptide and anti-GAD-65 toward patients’ clinical manifestations needs to be further explored. Hence, the aim of current study was to identify the association of anti-GAD65 with c-peptide and clinical characteristics in children with T1D.METHODS: Case-control study involving 47 T1D children (T1D group) and 41 healthy children (control group) younger than 18 years old was conducted. Secondary data regarding subjects’ demographic characteristics and medical history were collected from subjects, and serum blood was drawn from each subject for the anti-GAD65 and c-peptide measurement. Anti-GAD65 and c-peptide levels were measured using an Enzyme-Linked Immunosorbent Assay (ELISA) methods.RESULTS: Anti-GAD65 antibody was detected in 78.7% T1D group, while only 2.43% were detected in control group subject (p=0.0000). The c-peptide level of T1D group was 0.07±0.19 nmol/L and control group was 1.5±0.77 nmol/L (p=0.0000). The total daily dose of insulin in subjects with positive anti-GAD65 was greater than in the negative anti-GAD65 (p=0.012). The sensitivity and specificity of the anti-GAD65 were 85.4% was 66.7%, respectively.CONCLUSION: The results of this study show that anti-GAD65 was associated with total daily dose of insulin requirement in children with T1D.KEYWORDS: diabetes mellitus, type 1 diabetes, anti-GAD65, c-peptide

BACKGROUND: Neurodegenerative diseases are characterized by the loss of neuronal function in the nervous system. In recent years, more than 45 million people worldwide have suffered from progressive loss of memory and cognitive functions caused by Alzheimer’s disease. Ocimum sanctum is one of the medicinal plants known to have neuroprotective abilities. This study was conducted to elucidate the anti-apoptotic effects of ethanolic extract of O. sanctum (EEOS) on PC12 and SH-SY5Y cells as well as interaction between main compounds of EEOS and β-amyloid (Aβ) peptide through in silico molecular docking.METHODS: The viability of TMT-induced PC12 and SH-SY5Y cells was assessed with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and acridine orange/propidium iodide staining. Cell proliferation rate was measured with cell counting kit-8 (CCK-8) assay. Nuclear fragmentation was observed with Hoechst 33342 staining. Caspase -3 and -9 expressions were measured using enzyme-linked immunosorbent assay. Interactions between main compounds of EEOS and Aβ were visualized with in silico molecular docking.RESULTS: EEOS had the potential effect of maintaining cell viability, preventing the cell’s morphological changes, and inhibiting apoptosis via the caspase pathway in PC12 and SH-SY5Y cells. Meanwhile, flavonoid K, phenol, eugenol could interact with the active site of Aβ through hydrogen-bonding and hydrophobic interactions.CONCLUSION: EEOS could prevent neuronal cell apoptosis via downregulation of caspase-3 and -9. Main compounds of EEOS could interact with the active site of Aβ, and thereby might inhibit Aβ oligomerization. Thus, EEOS and its main compounds could be potential as neuroprotective agents for preventing neurodegenerative diseases.KEYWORDS: Ocimum sanctum, anti-apoptotic, β-amyloid, caspase, neurodegeneration

Fossil fuels, climate change, and the vital role of CO2 to people and plants on planet Earth
Authors: SHANMUGAM Ganapathy
Published: August 2023

A rigorous examination of empirical data confirms the fact that there is no threat from CO2 to People. Fossil Fuels (i.e., Oil, Natural Gas, and Coal) are the underpinning of modern living in the 21stcentury and that CO2 is essential for the thriving of both People and Plants. The geologic record shows that the Earth’s climate has always been changing naturally during the past 600 million years in terms CO2 and temperature, without CO2 emissions from Fossil Fuels by humans. Aplot of CO2vs. Temperature for the last 600 million years shows basically no correlation for most of this time (Berner, 2004; Scotese et al., 2021). If the Net-Zero CO2 policy were to be implemented in 2050, large numbers of people would die and the modern human civilization would come to a sudden halt, and humans left alive would have to revert back to the lifestyles of the Neanderthals. A climate-change model for 200 years (1900─2100) is proposed based on four basic parameters, namely, CO2, Temperature, Population, and GDP (gross domestic product) per capita. In this model, calculations based on the Max Planck’s Curve by Van Wijngaarden and Happer (2020), an increase in Temperature by 2100 would be trivial even if CO2 is nearly doubled in value to 800 ppm. The CO2 in the atmosphere helps not only to modulate the Earth’s Temperature suitable for human survival, but also to enhance Global Greening.
Niemieccy myśliciele w Polsce. O działalności naukowej i translatorskiej Elżbiety Paczkowskiej-Łagowskiej wspomnienie pośmiertne

Published: August 2023

In this analysis my aim is to highlight the achievements of Elżbieta Paczkowska-Łagowska in the study of German ideas. A secondary aim of the consideration is to demonstrate that it is to Elżbieta Paczkowska-Łagowska that we in Poland owe the knowledge of some German names which, although important for the doctrinal map of the world, would not be known in Poland if it were not for her work. Out of the enormous number of publications by the industrious researcher and translator of the works German thinkers, two figures have been selected to show the broad spectrum of Elżbieta Paczkowska-Łagowska’s scientific research and to highlight her exceptional contribution to the introduction of German philosophers, thinkers or essayists into the scope of interest of Polish science. These include Helmuth Plessner, the founder of political anthropology, and Golo Mann, a historian and political scientist. Both thinkers would not be known in Poland if it were not for the translating and scientific efforts of Paczkowska-Łagowska. The choice of these two German scholars was dictated by the symbolic illustration of the main research of the author of The Logos of Life, the essence of which is the study of man and history.
Prediction of nanoplastics aggregation in wastewaters
Authors: Peiponen Kai-Erik , Roussey Matthieu
Published: August 2023

Discarded plastic wastes are slowly degrading into smaller parts, namely microplastics, that can be easily transported to oceans by water streams. In vast, salty, and sunny environments, they degrade even faster and are subject to come back in the water network used for drinking or industrial water in the form of nearly indetectable objects: nanoplastics. Once in busy buffers such as wastewaters, nanoplastics will tend to aggregate to form tertiary microplastics formed of single or multiple types of plastics and potentially host other materials ranging from organics and metals to bacteria and viruses. Their nature, random shape, and various size are at the origin of nuclei merging together or with other objects. Two particles at a close distance from each other can either attract or repulse themselves depending on their nature and constitution. At very short distances, Van der Waals forces are predominant and a measure of them is given by the so-called Hamaker constant. We propose to predict this aggregation by estimating the Hamaker’s constant.

A proposal for the regulation of the spectrum usage fee in 5G private network using fuzzy AHP
Authors: Hikmaturokhman Alfin , Ariansyah Kasmad
Published: August 2023

This study evaluates the types of regulation models for The Indonesia Spectrum Usage Fee—the so-called Biaya Hak Pengguna (BHP) Frequency in 5G private  network technology that are most suitable for implementation in Indonesia by implementing the Fuzzy Analytical Hierarchy Process (F-AHP) method. This method accommodates the opinions of telecommunications experts from mobile network operators (MNOs), regulators, vertical industries, and telecommunications consultants through a series of scientific steps to produce weights for each type of alternative solution offered. The results obtained show that the proposed model most suitable for implementation in Indonesia, taking into account the given criteria, is the one that uses unlicensed 5G frequencies. This model involves vertical industries not using licensed frequencies established by the government but rather choosing to use unlicensed frequencies to develop 5G technology for their own use. The implementation of this model is expected to encourage the optimization of regulation for Spectrum Usage Fee in 5G private network technology owned by the government, providing opportunities for vertical industries to develop 5G technology on private networks independently without relying on existing MNOs. This can stimulate innovation and technological progress in Indonesia to support Industry 4.0.
Noise reduction by greening
Authors: Attenborough Keith , Taherzadeh Shahram
Published: August 2023

Greening the environment can improve soundscapes by reducing unwanted sounds and introducing sounds that are generally considered more desirable. This review concentrates on the physics by which increasing the area of natural ground cover and vegetation can reduce sound levels. Most naturally occurring ground surfaces are porous. If a source of sound and a listener are close to a porous ground surface, the sound reflected from the surface combines with sound traveling directly to the listener such that the phase difference due to the path length difference adds to the phase change during reflection at the surface. At the listener, the two components will partly cancel each other; in other words, the direct and reflected waves interfere destructively, and there is a reduction in the total sound level over a range of frequencies. Also, viscous drag and heat exchange at leaf surfaces adds to sound attenuation. Measurements and predictions show that the viscous and thermal processes and ‘soft’ ground effect are the most important contributors to sound attenuation through crops and densely planted trees and contribute to the acoustical influences of roof top gardens and vegetated façades. Although widely used schemes for predicting outdoor noise allow for a porous ground effect and for attenuation through foliage, they are not sufficiently accurate either to explore the potential of ‘greening’ for noise reduction or to be useful in devising plans to exploit it. Improved prediction schemes are key to realizing the potential of greening for noise reduction.
Information Transfer Based on Brains Entanglement
Authors: mousavi seyed kazem
Published: August 2023

A human brain can communicate with another one’s brain using quantum entanglement. Similar particles can entangle without interaction. Sensory communication between two individuals from far distances is still not known. Former studies primarily have been performed regarding brain neurons' quantum behavior. The test was performed on two individuals far from each other. These individuals were put under the same music on the basis of brain neuroplasticity property. By activating the brain reward system, aligned thinking was time scheduled in these individuals’ brains. On the basis of entanglement, compressed information was sent and received between these two individuals.
A Comprehensive Study to Select a Cost-Effective Beam Design for Maximizing Power Density in a Cantilever Beam-Based Energy Harvester

Cantilever beams are the most widely used form of strain-driven energy harvesting, which uses piezoelectric materials. Although researchers are constantly seeking improved power output from cantilever-beam-driven piezoelectric energy harvesters, a systematic and fundamental analysis of the effect of beam geometry on the power capacity of energy harvesters warrants further investigation. Most of the previous research accounts for beams that are fully coated with piezoelectric material. While a larger coating area increases energy output, it also escalates costs as piezoelectric materials are very expensive. Considering the high cost of piezoelectric materials when dealing with limited piezoelectric material, enhancing power output can be achieved by employing a larger base beam and coating a portion of it at the fixed end. As such, the aim of this work is to investigate a wide variety of cantilever beam shapes (e.g., trapezoidal, triangular, V-cut, concave, and convex) with partial piezoelectric material coating on the base beam to maximize the power output capacity of the harvester. To ascertain a comparable argument, the surface area, volume, and mass of all the considered beam shapes are kept consistent, as these parameters influence the power output of the harvester. The geometry of each shape is systematically varied to understand the effect of geometric configuration on the output power density. Finally, the power capacities of all types of beams are compared, and a design is proposed to obtain the maximum power output. It was found that when the surface area of both the beam and piezoelectric material is kept constant and piezoelectric material is located at the fixed end, a trapezoidal beam with a smaller base width and larger free end width is the most efficient in generating power as long as the structural integrity is maintained. The finding is completely opposite as was suggested by previous studies, which proposed that a trapezoidal beam with a smaller free end yields higher output. Instead, this study demonstrates that an inverted trapezoidal beam produced higher output, considering partial coating compared to the full beam coating used in previous studies. Additionally, a correlation is presented on how the beam resonance frequency shifts with variation in beam parameters.

Introduction. This article’s subject is a dual function energy system that improves the quality of the electric energy with help of an active power filter and uses a new technique of command named ZDPC (Zero Direct Power Command) on one hand, and on the other hand it injects the photovoltaic (PV) renewable energy to the electrical networks in the presence of non-linear charges. The novelty of the work consists in the subtraction of disturbances resulting from the non-linear charges is provided by an active power filter based on a new ZDPC method. Methods. This strategy combines a classic PI controller for DC bus voltage regulation with a smart method to maximum power point tracking (MPPT) of power based on fuzzy logic. Purpose. The elimination of the undesirable harmonics from the source currents makes the current almost sinusoidal with a harmonic distortion rate close to 1 %. The injection of PV energy into the electrical grid is provided by a PV panel in series with a chopper through a two-state inverter. Results. This system is simulated using MATLAB/Simulink software. The results prove the robustness and feasibility of the ZDPC control which simultaneously guarantees the compensation of harmonic currents, the correction of the power factor and the injection of the solar power into the electrical grid.
