Unmanned aerial vehicles (UAVs) are aerial systems controlled remotely or autonomously by astronauts. Massive advancements in electronics and information technology have prompted the popularity and growth of UAVs. As a result of the huge advances made in electronics and information technology, civilian tasks can now be accomplished with UAV in a more effective, efficient, and secure way. Known as a drone, UAVs are developed and operated using a variety of technologies such as machine learning, computer vision, artificial intelligence, and collision avoidance. Having become more affordable and accessible, drone technology has become more popular among civilians. Therefore, this technology is constantly evolving and can be used across a variety of fields. The application of drones makes a huge difference in the most demanding and complex industrial environments such as those in the mining industry, maritime, oil, gas, and seaports. The usage of drones is increasing among industrialists to improve and optimize processes, as well as to enhance operational efficiency in industrial process. This chapter discusses UAVs on a wide range of topics, including evolution and historical perspectives of UAV, taxonomy of UAV, significance of UAV to society and industry, and industrial and academic perspectives on UAV.
In this paper, we attempted to review the soil erosion studies conducted throughout the globe using Revised Universal Soil Loss Equation (RUSLE). We searched the SCI, Scopus, Web of Science, Google Scholar database and various theses for this study. Though RUSLE is the most widely used model for estimation of soil erosion, the factors, namely rainfall erosivity, soil erodibility, slope length and steepness, cover management and conservation practice; vary greatly over different climatic zones, soil properties, slope, land cover and crop phase, respectively. Depending upon those variations, researchers have developed various sets of equations for different factors of RUSLE. These equations can be useful to map soil loss for many places on this planet.
The aim of the present study was to explore the nature of visual representations in biology textbooks across five educational boards across Asia through quantitative and qualitative content analysis. Descriptive statistics was used during the quantitative analysis. Qualitative content analysis involved a deductive approach where visuals in these textbooks were examined and categorized into different categories based on a newly developed typology and taxonomy of visual representation (coding scheme). Under this newly developed typology and taxonomy (coding scheme), visuals in biology textbooks can be categorized into 19 different categories. The findings of the study summarized the characteristics of visual representation usage in these textbooks in terms of their prevalence, distributional differences and trends. Through this study, a new perspective on the taxonomy and classification of visual representations, especially for biology textbooks, has been proposed. Biology teachers and textbook authors can gain insights through the findings of the study. Subjects: General Science; Biology; Secondary Education
Introduction: Saliva is a crucial diagnostic tool to evaluate oral health. Chewing sugar-free gum is an effective method to increase salivary flow and can also be employed a medium for the administration of medicinal ingredients. Aim: To evaluate and compare the effect of chewing xylitol, herbal and probiotic chewing gums on salivary acidogenicity levels. Materials and Methods: A single centre, randomised, doubleblind, multiple arm parallel clinical trial was conducted on 60 children aged between 6-11 years. Baseline salivary pH was recorded with the pH meter and then the participants were asked to consume chocolate and salivary pH was recorded at an interval of 5, 30, and 60 minutes. Then children were randomly allocated to Group A-Xylitol chewing gum (control group, n=20), Group B-Herbal chewing gum (n=20), and Group C-Probiotic chewing gum (n=20) and instructed to chew gum according to their assigned group and salivary pH was again recorded at an interval of 5, 30, and 60 minutes. The change in salivary pH was evaluated using one-way Analysis of Variance (ANOVA) and Post-hoc Bonferroni’s test. Results: The mean age of the study population was 9.23±1.38 years. Statistically significant (p<0.001) increase in pH was recorded post consumption of probiotic, xylitol and herbal chewing gums and the mean salivary pH values recorded at 60 minutes were 7.20±0.21, 7.01±0.23 and 6.43±0.22, respectively. Conclusion: The observations of the study showed that xylitol, herbal and probiotic chewing gums reversed the fall in salivary pH, after an acidogenic challenge with probiotic being better among the three groups.

The blunted nose cone with and without a sharp aerospike and an aerodisk of various diameters and lengths are investigated numerically in detail in the current study at a hypersonic Mach number of 10. The aerodisk diameter is described as d/D ratios such as 0.2, 0.4 and 0.6, and the length of the aerospike is represented as the L/D ratio of 1, 1.5 and 2. The main objective of the research is to examine the aerodynamic properties of blunt noses with and without aerodisks and aerospikes, as well as the influence of shock production over the model. The design of blunted nose cones with aerodisk was made up using CATIA and numerical investigation was performed on the ANSYS Fluent. The turbulence model of SST k-omega was considered for study. The current study revealed that shock patterns drastically varied nearer to the nose cone model at L/D ratio 2 and variation of drag reduction occurred due to the increase in d/D ratio and aerospike and also flow pattern over the model was clearly investigated.

Dermatophytes and Candida albicans are widespread with increasing prevalence and pose a grave threat to public health globally. Ocimum gratissimum and Mitracarpus scaber have been used in Southeastern Nigeria for several purposes, including antimicrobial effects, and have exhibited inhibition of growth to fungi. This study aimed to evaluate and ascertain the antifungal potential of these extracts against dermatophytes and Candida albicans. A total of 50 samples of dermatophytes and Candida albicans previously isolated from clinical samples at two different Hospitals, in the Southeast of Nigeria were used. The clinical samples were vaginal discharge, sputum, swab samples from the endocervix, urine, groin, mouth thrush, and palm. These organisms were all identified using standard mycological identification and characterization techniques. The sensitivity of selected fungi to the extracts (ethanolic extract of M. scaber and O. gratissimum oil) and ketoconazole was evaluated using a modified cup-agar diffusion plate method. The minimum inhibitory concentration (MIC) of the extracts was determined by the agar dilution method. Their minimum fungicidal concentration (MFC) and killing rates against the isolates were also determined. The organisms remain an important etiological agent in this species, implicated in several kinds of infections. The result showed that the activity of the O. gratissimum oil was comparable with that of the conventional drugs, indicating the potential in this extract. The MIC values for Candida isolates were consistently lower against O. gratisimum compared to ketoconazole. The MFC results indicated that O. gratissimum oil had a greater biocidal effect against most of the test organisms in contrast to ketoconazole. The killing rate study also indicated that the oil has very good activity against the isolates. O. gratissimum oil holds great potential for use in treating a wider spectrum of fungal pathogens.

The quality of software systems may be seriously impacted by specific types of source code anomalies. For example, poor programming practices result in Code Smells (CSs), which are a specific type of source code anomalies. They lead to architectural problems that consequently impact some significant software quality attributes, such as maintainability, portability, and reuse. To reduce the risk of introducing CSs and alleviate their consequences, the knowledge and skills of developers and architects is essential. On the other hand, ontologies, which are an artificial intelligence technique, have been used as a solution to deal with different software engineering challenges. Hence, the aim of this paper is to describe an ontological approach to representing and analyzing code smells. Since ontologies are a formal language based on description logics, this approach may contribute to formally analyzing the information about code smells, for example, to detect inconsistencies or infer new knowledge with the support of a reasoner. In addition, this proposal may support the training of software developers by providing the most relevant information on code smells. This ontology can also be a means of representing the knowledge on CSs from different sources (documents in natural language, relational databases, HTML documents, etc.). Therefore, it could be a valuable knowledge base to support the struggle of software developers and architects either to avoid CSs or to detect and remove them. The ontology was developed following a sound methodology. The well-known tool Protégé was used to manage the ontology and it was validated by using different techniques. An experiment was conducted to demonstrate the applicability of the ontology and evaluate its impact on speeding up the analysis of CSs.
Tuberculosis (TB) is an infectious disease caused by bacteria called Mycobacterium tuberculosis. The disease mainly affects lungs and causes pulmonary tuberculosis. It can also affect intestine, meninges, skin, bones and other tissues of the body. Although the drugs alone can cure TB, it still remains a major public health problem worldwide. The aim of the study was to assess the quality of life and medication adherence in TB patients. The Quality of life was assessed using SF-36 in patients receiving DOTS treatment in initial or continuous phase while the medication adherence was analyzed using Morisky Green Levine Scale. Subjects were also counselled about their disease during their first visit and a follow up was done after a month. A total of 152 subjects were enrolled in the study of which majority of the subjects had Pulmonary TB (55.26%). Diabetes was found to be the most common comorbidity followed by HTN. The average Physical Component Summary (PCS) and Mental component summary (MCS) were found to be 44.34 and 39.60 respectively. Females had a better quality of life scores compared to males. High adherence was seen in 32.24% of patients while 28.29% had low adherence. Follow up was done for 135 subjects. 15 subjects defaulted and 2 of them died. There was a significant increase in the QoL scores and medication adherence after one month. A significant association was found between the Physical functioning (p=0.001) and emotional wellbeing (p=0.01) with Duration of treatment indicating that subjects who had completed more than one month of their treatment had marked improvement in Physical functioning and emotional well-being scores
The planned opening of foreign universities will foster cultural exchange, expose Indian students to diverse perspectives and promote international understanding, according to Gedam Kamalakar. Foreign university campuses have the potential to attract foreign investment, create job opportunities and stimulate the local economy through increased spending on infrastructure, accommodation and services. Partnerships with foreign universities on joint research projects will enhance knowledge exchange and technological advancements. Nevertheless, the influx of foreign universities can pose a threat to domestic educational institutions by alienating talented students and faculty and exacerbating inequalities in access to quality education. There is hence a danger of cultural imperialism. Indigenous knowledge and traditions may be marginalised due to the dominance of Western educational systems and values. Increasing opportunities to study abroad may also increase brain drain.
Introduction: Loco-regional anesthesia role is increasingly important in surgery, especially in postoperative pain control. Using ultrasound-guided techniques has made the loco-regional approach increasingly safe and manageable, guaranteeing excellent analgesic results and patient compliance. This bibliometric research aimed to identify the most influential papers on the adductor canal blocks and outline their characteristics. Methods: All articles published from 1980 to 2022 were included in the Web of Science, PubMed, and Scopus databases and found using the keywords “Adductor canal block” or “Saphenous nerve block” or “Peripheral nerve block” or “Hunter canal block” or “Subsartorial canal block” or “ACB” or “Knee” or “TKR” or “TKA” or “Analgesia” or “Arthroplasty” or “Replacement” in the title section had bibliometric analysis performed. The first 25 papers were selected and analyzed by the number of citations. The correlation between numerical variables was evaluated using the Pearson Correlation coefficient. Results: Literature screening found 252 publications. One hundred ten were only about the adductor canal block. Of these, 25 articles were selected for our bibliometric study, published in 8 different journals and with a total number of citations equal to 1.457. “Regional Anesthesia and pain medicine” journal – with 9 articles – was the one that produced the most. There was a significant strong correlation between the n. of citations and the citation rate (R = 0.84, p < 0.001). Conclusion: The purpose of this study is to be a guide on regional anesthesia and, particularly, on adductor canal block, making the most effective as well as the most cited articles available to anesthesiologists or other researchers interested in this topic.
Datura arborea Linn is a sacred plant known for over 3000 years to have been used for magical and curative purposes. It was shown to have a central nervous system depressant effect. The active substances identified were tropane alkaloids: atropine, scopolamine, and hyosine. Therefore, we aimed to find out whether the ethanol extract of Datura arborea Linn has sedative and hypnotic activity. The extract was subjected to a thiopental sodium-induced sleep test and diazepam was used as a standard drug. The plant possesses sedative-hypnotic qualities, the findings indicate that doses of 35 mg/kg (2.70.24 min), 70 mg/kg (3.80.19 min), and 140 mg/kg (4.30.20 min) decreased the control's (9.2 min) latency to fall asleep. In comparison to the control, the length of sleep was increased by 23.46 minutes for 35 mg/kg (99.002.99 min), 70 mg/kg (132.605.53 min), and 140 mg/kg (118.606.04 min), respectively. The present study established the acute toxicity of Datura arborea Linn to be less than 600 mg/kg in mice. This study indicated that the ethanol extract of Datura arborea Linn has a sedative-hypnotic activity in the diazepam-induced sleep test. It is safe to suggest that the extract acts via either β-receptor by causing hyperpolarization or a decrease in spike activity in the cell, leading to relaxation, but these effects were not blocked by β-antagonist or α2-receptor to decrease acetylcholine release, leading to relaxation of the smooth muscle.

The purpose of the study was explored to find out the land and aquatic plyometric training on vital capacity among college men athletes. For the purpose of the study, forty five (n=45) men college athletes from Pudukkottai, Tamilnadu, India during the year 2019-2020 were selected as subjects. Their ages were from 18 to 21 years. The selected participants were divided at random into three groups of fifteen each (n=15). Group-I underwent land plyometric training, group-II aquatic plyometric training, and group-II acted as control group. The duration of the training period was restricted to eight weeks and the number of sessions per week was confined to five. The selected variable vital capacity was assessed by wet spirometer. The data were collected prior to and immediately after the training period of twelve weeks. The data obtained from the experimental groups before and after the experimental period were statistically analyzed with analysis of covariance (ANCOVA). Whenever the ‘f’ ratio for adjusted post test means was found to be significant, the scheffe’s post hoc test was applied to determine the paired mean differences. The level of confidence was fixed at 0.05 level for all the cases. The results of the study showed that aquatic plyometric training group is better than land plyometric training group and control group on improving vital capacity.

Background: Salmonella typhi (S. typhi) antibodies may be considered as biomarkers of typhoid fever, a severe febrile systemic illness caused by an invasive Gram-negative Bacterium S. typhi. Worldwide, about 21-26.9 million cases of typhoid fever and 200 000-215 000 deaths, occur annually. Between 2003 and 2005, statistics have shown a rising trend in the incidence of typhoid fever in Abia and Enugu States. The aim of the study was to determine the sero-prevalence of S. typhi antibodies in some rural communities of Abia and Enugu States as proxy indicators of prevalence typhoid fever (TF) in the two states. Methods: This was a cross-sectional study of the sero-prevalence of S. typhi antibodies in ten rural communities of Umunneochi Local Government Area (LGA) of Abia State and Ezeagu LGA of Enugu State using 421 (200 in Abia and 221 in Enugu) blood samples for the Widal test to determine the titres of these antibodies. Results: In the Abia communities the mean sero-prevalence of S. typhi antibodies was 68.2%, while in Enugu it was 87.1%. Between the two states, difference in the sero-prevalence of S. typhi antibodies was significant (p=0.03). Conclusions: The sero-prevalence of S. typhi antibodies was higher (87.1%) in the Enugu communities, compared to the Abia communities (68.2%). To reduce the incidence and prevalence of TF in the communities, access to safe domestic water, improved sanitation and good food hygiene needs to be improved. Health-seeking behaviour also needs improvement.
