Inguinal hernia repair is one of the most common procedures performed in general surgery. Approximately 20 million hernia surgeries are performed every year worldwide. Conventionally, hernial repair is carried out with the open Lichtenstein technique; however, laparoscopic and robotic inguinal hernia repairs have been developed as a minimally invasive alternative to the classic Lichtenstein repair. The prosthetic mesh can be placed by totally extraperitoneal and transabdominal pre-peritoneal approaches. Choosing the best technique for repairing an inguinal hernia is a challenge because the available data are contradictory. However, a growing number of studies have claimed that robotic-assisted hernia repair is not only feasible and safe, but it is associated with outcomes that are comparable to those obtained with laparoscopy and open surgery, including shorter hospital stay, and fewer complications. The aim of the review article is to provide an overview of the current practice of inguinal hernia repair, with a focus on the advances in robotic-assisted inguinal hernia repair, as well as the advantages and disadvantages of this surgical procedure compared to the laparoscopic technique in view of the current reports in the literature.
The main purpose of the paper is to determine the correlation of consumers' demographic factors on the impulse buying behavior with respect to a number of single impulsivity indicators and one collective indicator. The paper consists of theoretical and research aspects. The first part encompasses theoretical insights into the secondary research regarding impulse buying while the practical part presents the methodology and primary research results. With respect to the subject matter, research goals as well as previous findings and primary research results, corresponding hypotheses were set and mainly confirmed. Inter variable correlation and regression analysis has been performed to test the hypothesis. The results showed that demographic factors, such as the disposable income and age, are related to most impulse buying indicators and to the impulsivity collective indicator. However, educational qualification and gender produced marginal association with impulsive buying behavior. The paper also summarizes research limitations as well as the work contribution and future research guidelines.
This study was conducted to optimize the integration of solar-photovoltaic-distributed energy resources (SPVDERs) within the Nigerian power system networks using an AI-based Particle Swarm Optimization (PSO) Algorithm. By employing a mixed research method, primary and secondary data were gathered to calculate flow analysis, NR method's equations, PSO's position update model, particle swarm optimizer algorithm, and application modeling including Solar-PV DER modeling. The AI-based PSO algorithm design was developed for optimizing SPV-DER integration in Nigerian power system networks, and key parameters and variables that needed consideration were identified. The study also established how the performance of the AI-based PSO algorithm could be evaluated and compared with other optimization techniques for SPV-DER integration within Nigerian power system networks. The study's results showed that voltage limits were within acceptable ranges, and solar power contributions were estimated at 880.10MW with 46,718 panels needed. The study concluded and recommended that investing in AI-powered tools for efficient power distribution; monitoring and resource optimization for sustainable energy sources would optimize performance and unleash Nigeria's sustainable energy potential.
2-Pyrazolines are well known, and important nitrogen-containing five-membered heterocyclic compounds which belong to the family of azoles and have been found to possess considerable activities, like anticancer, antibacterial, antifungal, immunosuppressant and antiamoebic activity. In the present work, ten novel pyrazolines were prepared from chalcones, characterized and evaluated for their antibacterial activity against Staphylococcus aureus and Escherichia coli using Ciprofloxacin as standard and using DMSO as a solvent. Their activity was evaluated by measuring the zone of inhibition in mm. All the compounds exhibited antibacterial activity against Staphylococcus aureus and Escherichia coli. Among ten derivatives of compounds synthesized, the derivative with 2-chloro and 4-chloro substituted phenyl rings attached to pyrazolines exhibited the highest activity against both types of organisms. The derivatives with an unsubstituted phenyl group attached to pyrazolines exhibited comparatively less activity. Thus it can be concluded that pyrazolines containing substituted phenyl groups are effective broad spectrum antibacterial agents, and they can be developed as effective antibacterial agents.
India's hotel and hospitality industry occupancy decreased significantly in the first quarter of 2020, as the outbreak of COVID-19 affects different segments of the market. The outbreak of the novel coronavirus (COVID-19) has inflicted a blow on industries around the world, but maybe none as devastating as hospitality and travel. Depending on the length of the pandemic, companies across the industry adjusted growth forecasts for 2020, estimated profits to be conservatively 40-50 percent lower than expected before the outbreak. The effect on hospitality demand is greater than many other sectors, but even among hotels, air and cruise ships, and restaurants it is varied. Hotels and airlines operate at half capacity, with both business and leisure travelers canceling scheduled trips and not arranging any for the near future.The present article aims to study some novel practices for the survival of hospitality industries once the lockdown is over.
The Fourth Industrial Revolution (4IR), internet definition is considered as growing out of the third industrial revolution, but is considered a new era rather than a continuation because of the explosiveness of its development and the disruptiveness of its technologies. It is not a new phenomenon that many South African manufacturers are facing important talent challenges when organising their business. Diverse IT skill sets, improved skills blend and a rearrangement of skills are necessary. It is undisputed that 4IR requires a highly skilled workforce, and one which South Africa, regrettably, has been struggling to produce. It was the purpose of the study to gain an understanding of what Essential Employee Knowledge Management and Re-Skilling is needed in the South African Automotive Industry towards 2030 with regards to the Fourth Industrial Revolution (4IR). Methodology: Firstly, an environmental scanning was performed, examining pertinent literature, thereafter a case study approach was used was used to describe the true experiences of assembly workers and their immediate supervisors in a South African automotive plant. Results: The automotive industry is extremely robust and skilled employees are essential. From the study, the major solution to remedy low competence was continuous skills transfer through highly structured cross-functional skill development programmes. Conclusion: The study results cannot be generalised but do give an insight into what the current situation is in an automotive industry in South Africa.
Purpose Noise pollution is a common health hazard worldwide which is emitted along with chemical air pollutants, simultaneously from many sources. Some studies have been conducted to control these pollutants, simultaneously with promising results being achieved. Dielectric beads have been used in air pollution control technologies, successfully and probable effectiveness of them in noise reduction can be promising in dual use of them in the exhausts emitting noise and air pollution, simultaneously. Methods In order to investigate the effectiveness of dielectric beads in noise reduction, two types of them; namely glass and ceramic beads, were placed separately inside the connecting tube of a double-expansion chamber muffler. Then the transmission loss (TL) of muffler was examined using impedance tube. A factorial design was used to evaluate and optimize the effect of noise related parameters on TL of such a system. Results Results show that the presence of dielectric beads has significant effect on TL of muffler. The maximum TL was obtained as 74.76 dB for muffler with ceramic beads, under the optimal condition of 5250 Hz and 120 dB. Measurement of TL and sound absorption coefficient (SAC) of glass and ceramic beads showed that the noise reduction in muffler with ceramic and glass beads is probably due to SAC in ceramic beads and noise reflections in glass beads, respectively. Conclusion These results promise the dual use of dielectric beads in the exhausts emitting noise and air pollution simultaneously.

ABSTRACT Background: The coronavirus disease (COVID-19) infection rate and mortality among Nigerian health care workers appear to be on the increase. Aside from health workers, it has caused millions of infections and deaths worldwide. This study determined the level of knowledge, attitude, and practices of nursing and midwifery students towards COVID-19 in a North-Eastern Nigerian state. Methods: A total of 156 respondents were involved in this institutional-based cross-sectional study, conducted after the lockdown period. A total of 17 questions were used to assess the KAP with knowledge appraised with 12 questions, attitudes with 2 questions, and practices with 3 questions. Results: The majority of the students (53.80%) possessed a good level of knowledge regarding COVID-19, while 40.4% had fair knowledge regarding COVID-19 with only 5.80% having poor knowledge of COVID-19. The mean knowledge of COVID-19 in this study was 9.40±1.353 with an overall 78% correct answer rate. A vast majority of the respondent (82.7% and 98.1%) had strong confidence in Nigeria and believed that the pandemic will soon be over, respectively. Only a few avoided large gatherings of people (30.8%) with the vast majority reporting to have worn a mask when going out (84.6%) and washing their hands with running water and soap frequently as recommended (73.1%). In multiple logistic regression analyses, the COVID-19 knowledge score (OR: 0.39-0.40, 95%CI: 0.26 – 0.62, P<0.05) was significantly associated with a lower likelihood of negative preventive practices towards COVID-19. Conclusions: The participants in this study showed good knowledge, positive attitudes, and good practices toward COVID-19. There is still a need to strategize and implement periodic educational interventions and training on infection control practices among healthcare workers including students.

The significance of fermentation is gaining more relevance due to the need for better preparation of plants, the desire for better plant constituents, and the aim for the preservation of medicinal plants. Hence, this study sets out to determine and compare the pH, proximate composition, chemical constituents, antioxidant, and antimicrobial effects of 3-day and 7-day fermented seeds of Nigella sativa. The fermentation of the seed was done for 3 and 7 days using 2.5% sugar. The pH of the sample declined from 3.5 to 3.45 during the fermentation. The proximate composition (moisture, ash, lipid, protein, and carbohydrates) was higher for the 3-day fermented sample while fiber was higher for the 7-day sample. The phytochemical constituents (tannins, saponins, phenols, alkaloids, flavonoids, phytates, oxalates, terpenoids, steroids, and glycosides) were higher for the 3-day than the 7-day sample. The Gas Chromatography-Mass spectrometry technique showed peaks that were characterized as 17 and 20 constituents on days 3 and 7 of the sample, respectively. The antioxidant capacity (ranging from 35.50% to 82.69% for the 3-day and from 37.50% to 84.99% for the 7-day sample) varies by the increasing concentration (7.81 mg/mL to 1000 mg/mL) of the sample. The diameter of zones of inhibition tested at different concentrations (25 mg/mL, 50 mg/mL, and 100 mg/mL) showed varying degrees of activity against Proteus vulgaris and Staphylococcus aureus. The zones obtained were higher 8-10 mg/mL against Staphylococcus aureus and 10-12 mg/mL against Proteus vulgaris for the 7-day fermented sample while 8.0 to 9.0 mg/mL was obtained for the 3-day fermented against Staphylococcus aureus and 8.0 to 10.0 mg/mL against Proteus vulgaris. Overall, the results of this study indicated that fermentation contributed to enhancing the bioactive components and antioxidant capacity of the fermented seeds of N. sativa thereby supporting the use of fermentation in the production of value-added functional foods.

Background: Exhaust noise is known to be a major pollutant in the environment and workplaces due to the development of industry and transportation. Exhaust noise can be reduced to normal levels by mufflers or silencers. A reactive muffler efficiently dampens noise at low frequencies by reflecting sound waves. Therefore, muffler design is of great importance in exhaust noise reduction. Transmission loss (TL) is an essential characteristic of mufflers, demonstrating their acoustical properties. Any acoustical appliance is selected based on its damping performance and reliability. Predicting TL through experimentation is different from theoretical calculations. Methods: In the present study, a double-expansion chamber muffler was designed as a reflective muffler on a laboratory scale by equations. Next, TL was evaluated by an impedance tube applying a 4-microphone technique to determine the acoustical performance of the designed muffler. Results: Findings revealed that the TL of the muffler at 312 Hz frequency obtained 27.5 dB agreement with the required TL of the muffler of 25 dB. In addition, the TL of the muffler against frequency attenuates noise in broadband frequencies. Conclusions: These results indicated that the built muffler provides desired TL for exhaust chambers. Therefore, equations can be used as a precise method for muffler design. Furthermore, multi-expansion chamber mufflers are useful for reducing noise at a wide range of frequencies.
This study presents a comprehensive bibliometric analysis of household consumption research in Maharashtra from 2017 to 2023, highlighting shifts in academic focus before and after the COVID-19 pandemic. The analysis explores key research trends, including foundational theories like the Keynesian consumption function and Engel’s law, while examining how themes such as income-consumption relationships, inequality, and economic resilience have evolved. Through citation network analysis, publication trends, and thematic evolution, we identify the most influential works, authors, and institutions that have shaped this field. Pre-pandemic research centered on established economic concepts, exploring factors like income distribution, economic growth, and household debt as predictors of consumption. However, post-2020, there is a marked shift towards understanding financial resilience, the impact of income shocks, and the role of government interventions in stabilizing consumption patterns during crises. This transition reflects an adaptation of traditional consumption models to account for pandemic-induced economic disruptions, emphasizing financial literacy and digital transformation as critical areas of study. Our findings contribute to a deeper understanding of the drivers of household consumption research in Maharashtra, providing insights into the socio-economic factors that influence spending behaviors in both stable and volatile conditions
