Iot based smart transport management and vehicle-to-vehicle communication system

Vehicle-to-vehicle (V2V) communication is an advance application and thrust area of research. In the current research, the authors highlighted the technologies which are used in V2V communication systems. Advantage of such technology is that it helps to detect live location and tolling. It plays an important role if there are huge amount of traffic. The current research work can obtain more information about Li-Fi, RFID, VANET, and LORAWAN technology. Li-Fi is known as VLC communication system that uses visible light for high data transmission and reception. RFID technology helps the emergency vehicle to reach destination quickly by avoiding any kind of traffic. LORAWAN is a large-scale network technology with a long range and VANET with low power that allows to obtain accurate traffic information on each route and this saves time. The comparison between the different technologies is reviewed in order to obtain the optimized technology as per the applications.

Knowledge, attitude, and usage of hyoscine n-butylbromide in the management of labor among medical practitioners in nigeria

Background: Hyoscine N-butylbromide (HBB; Buscopan) is commonly used in obstetric practice to accelerate labor and facilitate cervical dilation, yet variability in knowledge, attitude, and clinical usage persists among practitioners. This study assessed the knowledge, attitude, and usage patterns of HBB among medical practitioners at Abia State University Teaching Hospital (ABSUTH), Aba, Nigeria. Methods: A descriptive cross-sectional survey was conducted between August 2024 and April 2025 among 102 medical practitioners directly involved in labor care at ABSUTH. A structured, self-administered questionnaire, validated through expert review and pilot testing (Cronbach’s α = 0.78), was used to collect data on demographics, knowledge, attitude, and usage patterns. Descriptive and inferential statistics, including Chi-square tests and Pearson correlations, were performed using SPSS v. 25.0. Significance was set at p < 0.05. Results: Among 102 respondents, 93.1% had heard of HBB, and 70.6% correctly identified it as an antispasmodic. While 69.6% recognized its primary mechanism as cervical relaxation, 48% were aware of contraindications. The majority agreed that it is effective (mean = 4.12) and improves maternal outcomes (mean = 4.01). About 85.3% had administered it during labor, mostly in the active phase (64.7%), with the intravenous route being most preferred (56.9%). Statistically significant associations were observed between knowledge and attitude (χ² = 18.442, p = 0.001), specialty and frequency of use (χ² = 12.695, p = 0.048), and formal training with dosage knowledge (χ² = 15.210, p = 0.002). Knowledge, attitude, and usage scores were significantly correlated (p < 0.01). Conclusions: While the majority of practitioners at ABSUTH are familiar with and frequently use HBB in labor management, knowledge gaps and variations in practice remain. Strengthening formal training and incorporating standardized protocols could improve evidence-based usage and maternal outcomes.

Simulation-based time-domain short-circuit fault evaluation and protection system reliability analysis in 300mva substations with 132kv transmission lines

This study conducted a simulation-based time-domain short-circuits fault evaluation and protection system reliability analysis in 300 MVA substations with 132 kV transmission lines in Asaba (Ibusa/Asaba), Delta State, Nigeria. The analysis focused on two primary parameters: protection system dependability and selectivity, to determine the conditions necessary for ensuring rapid fault clearance and stable substation operation under line-to-ground, double-line, and three-phase faults. Fault currents, voltages, and relay trip signals were generated and analyzed using MATLAB time-domain simulations. Results indicated that system dependability exceeded 97% and security surpassed 95% when total fault-clearing times remained below 120 ms. Relay coordination intervals of 0.2–0.4s, backup misoperation below 3%, and circuit breaker MTBF above 20,000 h ensured selective fault isolation. Extended fault durations beyond 120ms or improperly coordinated relay settings increased the likelihood of misoperation and voltage instability. It was concluded that uninterrupted substation operation depends on integrating time-domain fault evaluation, coordinated relay settings, and reliable breaker performance into protection management protocols. Accordingly, it was recommended that substation operators maintain precise relay coordination, implement continuous time-domain monitoring, and uphold breaker maintenance schedules. These actions will further enhance the protection reliability, reduce fault propagation risks and support safer, more stable operation of the 132 kV transmission network.

Evaluation of self-medication with antibiotics in libyan community

Self-medication of antibiotics is an irrational use of drugs, contributing to microbial resistance, increasing health care cost and higher mortality and morbidity. This study was aimed to assess self-medication with antibiotics without a medical prescription in the community of Libya. This is a cross-sectional study conducted from June to December, 2022 and the total number of participants was 200. The design of the study and sample size were modified according to the proficiency of pharmacists and the medical and non-medical population of Libya. The questionnaire was developed in English and Arabic language and was distributed through social media platforms. The questions were used after a thorough literature search and assessing the validity and reliability. The significant signs regarding reasons for the treatment by self-medication drugs of antibiotics, because of its various drugs of antibiotic by pharmacist (n = 80, 40.0%) and family (n = 90, 45.0%) compare with experience and physicians by used prescription was 13 (06.50%) and significant sings regarding by nasal congestion self-medication of various antibiotics (n = 100, 50.0%). This sign must be practiced based on a previous physician’s prescription. The antibiotics are often self-administered as patient feel that they will save money and time but this can lead to substantial adverse drug reaction, antibiotic resistance, treatment failure and drug-related toxicity. This study respondent's medical and non-medical public of Libya who should be relatively informed and educated about the risk of treatment by self-medication of antibiotics with the development of resistance.

Improving machine learning classification models for anaemia type prediction by oversampling imbalanced complete blood count data with smote-based algorithms

Computer-assisted disease diagnosis is cost-effective and time-saving, increasing accuracy and reducing the need for an additional workforce in medical decision-making. In our prior research, we trained, tested, and compared the accuracies of nine optimizable classification models to diagnose and predict eight anaemia types from Complete Blood Count (CBC) data. This study aimed to improve these classification models by oversampling the original imbalanced dataset with four algorithms related to the Synthetic Minority Over-sampling Technique (SMOTE). The results showed that the validation accuracy increased from 99.22% (Ensemble model) to 99.57% (Tree model), and most importantly, the False Discovery Rate (FDR) for the anaemia type with the highest FDR decreased from 23.1% to 1.5%.

Live bird markets in nigeria: a potential reservoir for h9n2 avian influenza viruses

Since 2006, multiple outbreaks of avian influenza (AI) have been reported in Nigeria involving different subtypes. Surveillance and molecular epidemiology have revealed the vital role of live bird markets (LBMs) in the dissemination of AI virus to commercial poultry farms. To better understand the ecology and epidemiology of AI in Nigeria, we performed whole-genome sequencing of nineteen H9N2 viruses recovered, from apparently healthy poultry species, during active surveillance conducted in nine LBMs across Nigeria in 2019. Analyses of the HA gene segment of these viruses showed that the H9N2 strains belong to the G1 lineage, which has zoonotic potential, and are clustered with contemporary H9N2 identified in Africa between 2016 and 2020. We observed two distinct clusters of H9N2 viruses in Nigeria, suggesting different introductions into the country. In view of the zoonotic potential of H9N2 and the co-circulation of multiple subtypes of AI virus in Nigeria, continuous monitoring of the LBMs across the country and molecular characterization of AIVs identified is advocated to mitigate economic losses and public health threats.

Clinical profile of glaucoma patients: a cross-sectional study at a tertiary eye center in bangladesh

Background: Glaucoma is a group of disorders that can lead to irreversible vision loss if untreated. It affects individuals across all ages, genders, and ethnicities, with intraocular pressure (IOP) being the only modifiable risk factor. Regional studies highlight variations in the prevalence of glaucoma subtypes, underscoring the need for population-specific data to guide effective prevention and treatment efforts. This study aimed to explore the clinical characteristics and patterns of glaucoma patients in a tertiary care setting in Bangladesh. Methods: This was a hospital-based cross-sectional study, conducted from January to December 2023 at the Glaucoma Department of Deep Eye Care Foundation. A total of 2,172 individuals aged 20 years and above were conveniently selected as the study population. After explaining the study objectives, written informed consent was obtained from all participants. Ethical approval was obtained from the institutional review board of the Deep Eye Care Foundation. Data analysis was performed using the Statistical Package for Social Sciences (SPSS), with a P-value of less than 0.05 considered statistically significant. Results: The study population predominantly consisted of middle-aged and older adults, with a slightly higher proportion of females than males. Most participants were housewives, followed by farmers. A majority resided in rural areas rather than urban, and only a negligible number reported a family history of glaucoma. More than half of the patients presented with reduced visual acuity. The average IOP was nearly similar in both eyes. Most cases showed bilateral involvement of glaucoma. The predominant types of glaucoma were primary angle-closure suspects (PACS) and primary open-angle glaucoma (POAG). The main treatment approaches included beta-blockers and laser peripheral iridotomy, while a notable proportion of patients were kept under observation. Conclusions: Bilateral involvement and reduced visual acuity were common, with PACS and POAG being the predominant subtypes. This study offers unique insights into the demographic and clinical profile of glaucoma in rural communities, emphasizing the need for communitybased screening, gender-sensitive eye care, and early detection to reduce visual disability.

Efficient detection of escherichia coli o157:h7 using a reusable microfluidic chip embedded with antimicrobial peptide-labeled beads

The ability of antimicrobial peptides (AMPs) for effective binding to multiple target microbes has drawn lots of attention as an alternative to antibodies for detecting whole bacteria. We investigated pathogenic Escherichia coli (E. coli) detection by applying a microfluidic based biosensing device embedded with AMP-labeled beads. According to a new channel design, our device is reusable by the repeated operation of detection and regeneration modes, and the binding rate is more enhanced due to even distribution of the bacterial suspension inside the chamber by implementing influx side channels. We observed higher binding affinity of pathogenic E. coli O157:H7 for AMP-labeled beads than nonpathogenic E. coli DH5α, and the fluorescence intensity of pathogenic E. coli was about 3.4 times higher than the nonpathogenic one. The flow rate of bacterial suspension should be applied above a certain level for stronger binding and rapid detection by attaining a saturation level of detection within a short time of less than 20 min. A possible improvement in the limit of detection in the level of 10 cells per mL for E. coli O157:H7 implies that the AMP-labeled beads have high potential for the sensitive detection of pathogenic E. coli at an appropriate flow rate.

Effect of occupational exposure on hematological and biochemical parameters in workers at oil and gas companies

Petroleum refineries are largest chemical industries that are responsible for emission of several pollutants into the atmosphere. Benzene and its metabolites are regarded as the most hazardous compounds that are emitted by petroleum refineries. These contribute to toxic oxidants, which cause many serious health risks to petroleum refineries workers. This study was aimed to analyze the effects of chemical exposure on hematological and biochemical parameters among workers at Zawia oil refinery and Mellituh oil and gas refinery companies. A total of 200 workers participated in this study which consisting of two equal groups (each group: n = 100). The first group consists of petroleum refineries workers and the second group consists of non-oil work civil servants serving were recruited as exposed and control subjects, respectively. The results of blood picture, liver enzymes and kidney functions were compared between the groups. Mean white blood cells counts, platelet counts, and hematocrit count were significantly higher, while the mean red blood cells count was insignificantly changed in petroleum refineries workers. While the mean hemoglobin and corpuscular hemoglobin concentration levels were significantly lower, whereas the mean corpuscular volume and mean corpuscular hemoglobin levels were insignificantly changed in petrol refineries workers. Liver enzymes and renal functions were significantly higher in petrol refineries workers. The present findings indicate that occupational exposure to benzene causes significant alterations in hematological and biochemical parameters and workers are at high risk of developing blood, hepatic or renal related disorders. Protection and frequent medical attention should be given to petroleum refineries workers.

An exhaustive review on state-of-the-art techniques for anomaly detection on attributed networks

Social Network sites are one of the most prominent websites used in almost every facet of life. A social network reflects relationships among social entities, including acquaintances, co-workers, or co-authors. With the extreme success of Social networks, the misuse has also been escalated and unlocked the way for various illegal behavior and security threats. Social Network anomaly detection has become a critical topic to be explored by researchers. The nature of the input data is a significant aspect of an anomaly detection technique. In the field of anomaly detection in the social network, input networks can be classified as static or dynamic, Attributed or unattributed. The number of nodes and the connections between the nodes in static networks would not change with time. Attribute networks are pervasive in various domains and constitute a vital element of modern technological architecture, where node attributes support the topological structure in data exploration. While social networks build up over time, evaluating them as if they had been static is very beneficial. Numerous studies have been done for Anomaly detection, but to the best of our knowledge, research in static attributed anomaly detection has been very limited. This review tries to portray earlier research on detecting anomalies for social static attributed networks and thoroughly discusses state-of-the-art embedding approaches

Effects of management competence, firm-level institutions and hrm bundles on the performance of private universities in ghana

The market for tertiary educational institutions, most especially for private universities, is highly competitive. The competitive nature of the market requires that Private Universities (PUs) step up their performance so as to remain competitive despite the major structural and market differences between them and public universities in the provision of tertiary education. The need for private universities to remain competitive in this turbulent market, calls for some careful examination of the factors that would enable private universities to enhance their performance. In this respect, this study sought to examine the effects of management competence, firm-level institutions, and human resource management (HRM) bundles on the performance of private universities in Ghana. Underpinned by the RBV and AMO theories, the study tested four hypotheses that sought to explain the relationships between the key variables of the study. The study was implemented using a quantitative research design. Out of the sixteen private universities sampled, thirteen private universities responded. The main research instrument was a structured questionnaire. Out of 230 questionnaires administered, 127 completed questionnaires were received and used for analysis. Collected data was analyzed using descriptive and inferential statistics (regression analysis) with the aid of SPSS software version 20 and AMOS version 23. Research findings from the tests of hypotheses established that management competence positively and significantly affected performance of private universities in Ghana. Though the study found that the composite variables of firm-level institutions and HRM bundles did not moderate the relationship between management competence and PU performance, the skills bundles (which is a component of the HRM bundles) significantly moderated the management competence – PU performance relationship in such a way that at high levels of skills bundle, management competence influences PU performance more than at low levels of skills bundle. Based on the findings of the study, it is recommended that PUs in Ghana institute competence acquisition and utilization policies, maintain appropriate firm-level institutions and HRM bundles and match these to their competence development strategies.

A study of foreign direct investment in indian electronics industry

The present study focused on analysing the FDI inflow in Electronics industry form year 2007 to 2018 in country and role of FDI in development of the electronic industry in India. As well identify the current status of Electronics industry in world and the share of India in the same. The present research work also attempted to take overview of various policies introduced by Government of India to promote the FDI in Electronics industry. The FDI inflows statistics reveals that the separate category of Electronics sector is created in year 2007 by DIPP for recording FDI inflow. And sector specific data published in DIPP factsheet revels that this industry has attracted 0.55 % of total cumulative FDI inflow in country till December 2018 which is very negligible share of overall FDI in country. The overview of policies revels that NPE–2012 to New NPE-2018 had attempted to provide multiple incentives for Foreign Investors to establish their electronic manufacturing facilities in country but very negligible response has been seen in response of the same. Further results of study reveals that due to various FTA’s & being signatory of WTO’s ITA-1 in year 1996 leads toward reducing competitiveness of electronic manufacturing in India and country become net importer of approximately 50% of overall domestic need of electronics products.

Aqueous extract of hybanthus enneaspermus exhibited aphrodisiac potentials in fluoxetine-induced sexually-impaired female rats

Hybanthus enneaspermus, traditionally used as an aphrodisiac was investigated for its potential to reverse antidepressant-induced sexual dysfunction in female rats. The aqueous extract was evaluated for secondary metabolite, amino acid and mineral constituents. Alkaloids, tannins, flavonoids, anthraquinones, steroids, terpenoids, phenolics, calcium, potassium, sodium, glutamine and leucine are some of its notable constituents. 60 healthy, sexually responsive female albino rats (144.7±5.9 gm) were divided into six groups (A-F) of 10 rats each; of which 50 were induced into sexual dysfunction. Rats in group A were administered distilled water throughout the experimental period and served as a control group, while rats induced into sexual dysfunction (Groups B-F) by fluoxetine were given water, the reference medication (Tadalafil) and oral doses of the extract (250, 500, and 1000 mg/kg body weight) once daily for seven days, respectively. When administered to sexually active rats, fluoxetine significantly decreased the frequency of darting, hopping, lordosis, genital grooming, and licking behavior by 57.4%, 42.5%, 43.9%, 64.0%, and 41.8%, respectively. However, the latency of darting, hopping and lordosis were significantly increased by 50.6%, 47.7%, and 54.9%, respectively. Hybanthus enneaspermus aqueous extract administered at doses of 250, 500, and 1000 mg/kg significantly reversed fluoxetine-mediated changes in all sexual behavior parameters. The extract's ability to reverse the characteristics of sexual behavior at 1000 mg/kg was comparable to those of tadalafil-treated rats. Additionally, all the extract dosages reversed the levels of blood luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin and estrogen after it has significantly been altered by fluoxetine. The results indicated that the aqueous extract of Hybanthus enneaspermus improved the proceptive, receptive and orientational behavior of rats. The extract also enhanced reproductive hormone concentration by restoring sexual competence in sexually-impaired female rats. The findings of this study provide further evidence in favor of Hybanthus enneaspermus widespread usage in the management of female sexual dysfunction.

Translanguaging and reading comprehension of filipino esl intermediate learners

This study investigated the connection between translanguaging and reading comprehension of Filipino ESL intermediate learners. The respondents were intermediate pupils enrolled in the selected central schools in Bicol, Philippines. The respondents' ages range from 8 to 12 years old, and 124 students (27.55%) were males while 326 students (72.44%) were females. The descriptive-correlational method was used in the study. The descriptive method was used to describe the reading performance of the ESL intermediate learners and their translanguaging factors, while Pearson Product Moment Correlation was used to determine the relationship between the two variables. The primary instruments used were validated teacher-made reading comprehension test and translanguage factors survey questionnaire. Data disclosed that the general reading comprehension of the ESL intermediate learners along with vocabulary, drawing inferences, and getting the main idea, are very satisfactory. Meanwhile, the different translanguaging factors, along with personal, teacher, and social, were surveyed and identified in the study. The statistical test revealed that the reading comprehension of the respondents was significantly correlated with the identified translanguaging factors. Thus, it is recommended that teachers should promote group discussions and allow open interactions in the classroom. Teachers should allow the use of both the home language and English; employ translanguaging pedagogy in teaching reading; foster an understanding and acceptance of linguistic differences; promote multilingualism, and allow indigenous languages to be used in education to facilitate meaningful learning.

Tonsillolith – a rare cause of halitosis and odynophagia in a 9-year-old girl

Tonsil stones, also known as tonsilloliths or tonsiliths, are usually tiny white or yellowish mineralized structures packed with organic debris and bacteria that develop in the enlarged palatine tonsillar crypt. Tiny tonsillitis is commonly detected in diagnostic imaging such as computed tomography (CT) and less so in panoramic radiography, with the prevalence increasing with age. Giant tonsilloliths are rare and most reported cases have been in adults, with only a few cases reported in the pediatric population. In this report, we described a 9-year-old girl who had suffered from halitosis for 6 months and odynophagia with oropharyngeal foreign body sensation for 2 weeks and was later diagnosed with a tonsil stone.

Bio-efficacy of insecticides and biorationals against the incidence of whitefly, bemisia tabaci (genn.) and yellow mosaic virus in mungbean

Whitefly, Bemisia tabaci (Genn.) and yellow mosaic virus disease incidence in mungbean, Vigna radiata (L.) Wilczek is a most serious problem in northern states of India. Bioefficacy of some insecticides and biorational were tested during kharif 2010 to 2011 and 2011 to 2012 at Pulses Research Farm, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar. The results revealed that 30 days after sowing minimum whitefly population was recorded in plots, when seeds were treated with dimethoate 5 ml/kg seeds. At three days after spray application lowest whitefly population (1.6 and 6.4 adults/ cage/ plant) was noted in NSKE 5 per cent sprayed plots. At seven days after spray, NSKE 5 per cent and triazophos 0.04% was the most effective in keeping the whitefly incidence and yellow mosaic virus infection low. Triazophos and NSKE did not help in managing the whitefly population at low level up to 10 days after spray application. Spraying of triazophos 0.04% resulted in higher grain yield as well as net profit. Lower dosage of triazophos 40EC at 0.02% enhanced the whitefly population in 2011 to 2012. However, the maximum incremental cost benefit ratio (1:13.41) was obtained in dimethoate 5 ml/kg seed treated plots followed by seed treatment with dimethoate plus spraying of triazophos 0.04% (1:11.93).
