The world is moving towards technological advancements and every industry is rapidly changing its approach. Thus, industry looks for more technically knowledgeable and analytically persons to adapt to the fast-changing world.(6) This revolutionized the higher education system across the world. The education system changes its traditional method of teaching to more practical based blended learning. Whereas, the maritime industry which used to take people at the age of 12 and train them at the ship for various works is also selecting their candidates with basic subject knowledge and analytical skills. Because at present the maritime education is more of traditional based theoretical learning. The maritime education course contents are designed in such a way that it should meet the minimum requirement of Standards of Training, Certification and Watch keeping for Seafarers (STCW) convention adopted by the International Maritime Organization (IMO) which were not been revised after 2010. The shipping companies are looking beyond this minimum requirement as the ship is automated and has more advanced machineries onboard the ship. The seafarers with more analytical and basic theoretical knowledge find it difficult to adapt them to the technologically advanced marine environment. The present students studying the maritime courses lack interest in studying the theoretical based traditional learning. Since the STCW conventions are under review, this paper discusses about the blended learning techniques which can be adopted to the course contents. The data has been collected using structured questionnaire from different set of people. The collected data was analyzed and validated using AMOS and SPSS software. The results shows that the blended learning techniques like Augmented reality and Virtual reality techniques considerably solves the problem. This technique also gives the student hands on training which will be more helpful when they are onboard.

Purpose: The present study examines the liquidity of the firm and its impact on financial distress, which may or may not increase the chances of bankruptcy. The study also analyzes the profitability, cash position, and solvency of the firm.Design/methodology/approach: We use the data of a listed Government manufacturing company and measure the financial distress and probabilities of bankruptcy to test the chances of financial distress during the period between 2015 and 2019. The financial models used for evaluation in the study are the Altman z-score model, Logit Probability model, and Falmur model.Findings: The study found that there was a chance of bankruptcy in the initial years, but later, it survived the bankruptcy. The study also established that the liquidity and solvency of the firm were not up to the standard.Practical implications: The result of the study extends our theoretical understanding and also provides valuable guidelines to reduce the chance of insolvency, bankruptcy, and financial distress of firms and to maintain the proper financial health of the firm.Originality/value: While many empirical studies investigate the relationship between liquidity position and its impact on financially distressed firms in the industry as a whole, but most do not consider the impact of financial distress in an individual firm or company. Most of the published studies use statistical tools for the evaluation of financial distress. This study uses Multiple Discriminant financial model analysis. Multiple Discriminant financial model Analyses are very useful in deciding remedial actions for financial distress problems.

The current study investigates the effects of friction stir processing (FSP) parameters on the mechanical and microstructural characteristics of the alloy AA6061-T6. The FSP's big-area stir zone is where the fine-equiaxed grains are created, and it was found that the size of the grain of every pass is homogenous there. The design of experiment (DOE) method has been used to identify the key variables affecting the final tensile strength. FSP was accomplished using threaded cylindrical pin profiles with three varying rotational speeds (930, 1100, and 1460 rpm) and various transverse speeds (23, 50, and 79), and the tilt angle of the tool was also set at 2°. The optimum FSP parameters were two passes at 1460 rpm and 79 mm/min with these values. It was found that the stir zone's center has a greater microhardness value of 235 kg/mm2 at three passes and that this value decreased toward the thermomechanically affected zone (TMAZ), HAZ, and base metal (107 kg/mm2). The result showed that the FSPed sample has a higher tensile strength at two passes than at one or three passes. Also, it was obtained from the ANOVA analysis results that travel speed is the most effective factor, giving 51.46% of the contribution feature pursued by No. of Pass (22.56%), followed by rotational speed (19.49%).

Transformers in general turned on by changing the state of the circuit breakers at several times. Usually, the circuit breakers are closed at various times to turn on the transformers. This process results in high inrush currents due to the asymmetric flux produced in the coil. In light of these facts, the purpose of this study is to provide a method for controlling the switching instant that take place during the inrush of a power transformer.The general idea is to calculate the pre-existing magnetic fluxes remaining on the base legs in terms of the three phase voltages. Then, using these data and equations, the optimal operating time is calculated to ensure that the inrush currents are reduced, and adjustment parameters are determined within the controller to obtain the least time difference between the control signals. The system was completely simulated within the MATLAB environment, and the fluxes and currents were shown without and with the controller, the results showed that the method used reduced the effect of the inrush currents with time differences of the order of milliseconds.

Sexual harassment experienced in childhood has a devastating impact on the physical and mental health of the survivors. In India, 53 percent of children below 18 years face sexual abuse. In most cases, the survivors remain silent sufferers. This research paper examines the case of X, who belongs to a lower socio-economic family in southern India and has suffered 11 years of sexual abuse. Her case demonstrates how children are abused in their closest circle and how their family fails to protect them from the abuse. This research also addresses the danger of easy access to abortion drugs without proper medical supervision, which can lead to mortality. It also emphasizes the need for comprehensive support systems for CSA survivors that include medical, psychological, and social interventions.

Now a day, the sports team coaches, trainers and other support staffs have a hectic job to deal with the preparation of their team players with consistent, precise and greater effort to meet the demands of the competition in shortest duration. Various training modalities were adopted depending upon the necessity that improves sports performance. Handball team coaches apparently felt that fitness and skill go hand in hand, where sports specific training caters to achieve this goal. Thus, the present study focussed on assessing the adaptations of maximal oxygen uptake and cardiovascular variables to handball game specific endurance circuit training. To accomplish the purpose twenty-four (24) trained university male handball players with a playing experience of more than eight years gave consent to participate. The selected twenty-four players were classified into two groups as Handball Game Specific Endurance Circuit Training Group (HGSECTG = 12) and Control Group (CG = 12). To test the effectiveness of handball game specific endurance circuit training (HGSECT) players performed specifically constructed handball circuit 3 days in a week for 12 weeks at 90-95% of maximal heart rate for two minutes duration and active recovery by walking. HGSECTG showed significant improvement on maximal oxygen uptake (t = 8.516, p < 0.05) and distance covered in Yo-Yo test also increased (t = 8.4, p < 0.05). Similarly, cardiovascular modifications are noted in maximum heart rate (HRPEAK, t = 2.372, p < 0.05) and resting heart rate (HRREST, t = 3.975, p < 0.05) and percentage of heart rate reserve (%HRRESERVE, t = 3.004, p < 0.05). We conclude that handball game specific endurance training programs could be sufficiently suitable to develop maximal oxygen uptake and positive adaptation of cardiovascular variables in twelve weeks of training among handball players. The intensity, duration, frequency and recovery of the intervention displayed improvement in VO2PEAK with reduced condition on cardiovascular stress.

Intelligent sports development in the recently emerged Internet-of-things era is especially dependent on the gathering and analysis of athletic big data based on widely dispersed sensor networks. Conventional sensors have drawbacks such a short lifespan and high maintenance costs, and they typically require a separate power source. Recently, independent sensing devices and mechanical energy harvesting have been made possible with the ability to transcend these limitations through the use of triboelectric nanogenerators, or TENGs. Most notably, TENGs can be made from the materials most commonly used in sports—wood, paper, textiles, and polymers. An overview of recent developments in TENG development for intelligent sports is provided. First, an explanation of TENG’s operation and how it relates to sports big data is provided. The creation of wearable technology and smart sports facilities, as well as TENG- based sports sensing systems, is then emphasized. Finally, the remaining difficulties and untapped potential are also covered.

This research focuses on addressing the problem of utilizing high-value sustainable materials in the creation of self-sensing concrete pavement. The study specifically explores the incorporation of reclaimed asphalt pavement (RAP), fly ash, and silica fume in a single mix design to achieve sustainability objectives. In the previous work by the authors, laboratory experiments were conducted to determine the optimal proportions of RAP, fly ash, and silica fume, with a focus on achieving desired mechanical properties. Mechanical tests, encompassing compressive strength, flexural strength, and indirect tensile strength, were conducted within this framework to assess the performance of the concrete mixture. The selected concrete mix in this study incorporated 40% RAP as a replacement for virgin aggregate, a fly ash-to-cement ratio of 0.8, and the addition of silica fume at 8% relative to the weight of cementitious materials. Structural health and durability were monitored in real time by embedding two electrodes within the concrete matrix. The results highlighted the significant impact of adding RAP, fly ash, and silica fume on the mechanical properties of the hardened concrete. The optimized combination design indicated improved strength and self-sensing behavior, which was related to the beneficial impacts of silica fume and fly ash on mechanical and self-sensing capabilities. This research contributes to the advancement of sustainable and intelligent infrastructure by demonstrating the feasibility of integrating recycled materials and self-sensing technology into concrete pavement construction. Additionally, the study extended its investigation to evaluate the performance of sustainable concrete under dynamic loads using ANSYS analysis. The investigation, which was performed on a structure with dimensions of 21 meters in length and 3 meters in width, observed that the use of sustainable materials improved the mechanical behavior of the structure under moving loads.
